Answer:
18 sq. units
Step-by-step explanation:
Height would be 6 and Length would be 3
6 x 3 = 18
For further help, use a coordinate grid and plot the points
Answer:
9 units
Step-by-step explanation:
We need to find the last point. This is a rectangle. We already have 3 corners. We need the opposite corner to (0,0). One corner has an x of 3 and a y of 0, another corner has a x of 0 and a y of 6.
We therefore know the fourth corner/point is (3, 6)
Now we can properly visualize the rectangle. If the rectangle has a corner at the origin, we can just use a formula and the other corner to find the area.
Area (rectangle) = 1/2 x length x width
The length will be the difference between the two x points (0 and 3) and the width will be the difference between the two y points (0 and 6).
Length = 3
Width = 6
Area = 1/2 x 3 x 6
Area = 9 units

Shelf A had 40 books and Shelf B had 16 books. After Katrina borrowed an equal number of books from Shelf A and Shelf B, there were 3 times as many books on Shelf A than Shelf B. How many books did Katrina borrow altogether?
Answer:
8 books; 4 from each shelf
Step-by-step explanation:
let x represent equal number of books from each shelf
from shelf A = 40 -x
from shelf B = 16 -x
shelf A has 3 times as many books than shelf B
3(16- x) = 40 -x
48 -3x = 40 -x
48 - 40 = -x + 3x
8 = 2x
x = 4
altogether she borrowed 4 + 4 = 8 books
Micha made a scale model of the Empire State Building. The building has an actual height of 381 meters. Micha’s model used a scale in which 1 cm represents 50 meters. What is the height in centimeters of michas model?
Micha's scale model of the Empire State Building is 7.62 centimeters tall
To determine the height in centimeters of Micha's scale model of the Empire State Building, we use the given scale where 1 cm represents 50 meters.
First, we find the scale factor for the actual height of the Empire State Building, which is 381 meters.
Using the scale, the calculation is as follows:
Actual height of Empire State Building = 381 m.
Scale ratio = 1 cm : 50 m.
Height of model in cm = Actual height (in meters) \/ Scale ratio (meters per cm).
Height of model in cm = 381 m / 50 m/cm.
Height of model in cm = 7.62 cm.
Therefore, the height of Micha's model is 7.62 centimeters.

Step-by-step explanation:
To find this average, add up the five data points given and divide your result by five (5):
(7 + 9 + 5 + 6 + 8) / 5 = 35 / 5 = 7
This group of students averaged 7 hours of sleep per night.
One pallet can store 15^5 water bottles. A stock room receives 15^13 water bottles.
Enter the number of pallets needed to store all the water bottles the stock room received.
___pallets
Answer:
3 pallets
Step-by-step explanation:
Divide to find the amount of pallets:
Subtract Exponents to divide
15^13 / 15^5 = 13 - 5 = 8 - 5 = 4 (subtracted 2 times)
You need three to store ALL the water
The stock room will need [tex]15^8[/tex] pallets to store the received [tex]15^13[/tex] water bottles since each pallet can store [tex]15^5[/tex] water bottles and we divide the total number by the pallet capacity.
To calculate the number of pallets needed to store all the water bottles the stock room received, we need to divide the total number of water bottles by the number of bottles a single pallet can hold.
The pallet can store 155 water bottles, and the stock room receives 1513 water bottles. By dividing the total number of bottles by the capacity of a pallet, the calculation is:
1513 ÷ 155 = 1513-5 = 158
Therefore, the stock room will need 158 pallets to store all the received water bottles.

mountain bike tire completes 20 revolutions and travels 136 feet. Rounded to the nearest inch, what is the diameter of the bike’s tire?
Answer: 26in
s=r*theta
r=s/theta
d=r*2
136ft=r*40pi
r=136/40pi=1.082ft
d=1.082*2=2.1645ft*(12in/1ft)=25.97in
Rounded to nearest in is 26in diameter
The diameter of the bike's tire is calculated by dividing the total distance traveled by the number of revolutions to find the circumference and then dividing the circumference by pi (π) to find the diameter, which is approximately 26 inches.
Explanation:To find the diameter of the bike’s tire, given that it completes 20 revolutions and travels 136 feet, we can use the relationship between the circumference of a circle (in this case, the tire) and its diameter.
First, we calculate the circumference of the tire by dividing the total distance traveled by the number of revolutions:
Circumference = Total Distance ÷ Number of Revolutions
Total Distance = 136 feet (1 foot = 12 inches, so convert feet to inches for precision)
Total Distance in inches = 136 feet × 12 inches/foot = 1632 inches
Circumference = 1632 inches ÷ 20 = 81.6 inches
Now, we use the circumference to find the diameter:
Circumference = π × Diameter
Diameter = Circumference ÷ π
Diameter ≈ 81.6 inches ÷ π ≈ 26 inches
Therefore, the diameter of the bike’s tire, rounded to the nearest inch, is approximately 26 inches.

Figure 1 is a square pyramid. Figure 2 is a right triangular prism.
Complete the following statement about Figures 1 and 2.
The surface area of Figure 1 is ___ square centimeters ___ than the surface area of Figure 2.
Answer:
the answer is
The surface area of Figure 1 is 10.2 square centimeters Less than the surface area of Figure 2.
Step-by-step explanation:
Figure 1
area of a square = s2
=9squared
=81 sq cm
area of triangle = 1/2 bh
=1/2 (9cm) (14cm)
=63 sq. cm
find surface area
SA = 81 sq. cm + 4(63 sq. cm)
SA = 81 sq. cm + 252 sq. cm
SA = 333 sq. cm
Figure 2 Calculation
area of rectangle = lw
a = (12cm) (8 cm)
a = 96 sq. cm
area of triangle = 1/2 bh
=1/2 (8 cm) (6.9 cm)
= 27.6 sq. cm
total surface are of figure 2
SA = 3 (96 sq.cm) + 2 (27.6 sq. cm)
SA = 288 sq. cm + 55.2 sq. cm
SA = 343.2 sq. cm
find the difference between figure 1 and figure 2
343.2 sq. cm - 333 sq. cm = 10.2 sq. cm
Final answer:
We cannot complete the statement definitively about the surface area comparison between the square pyramid and the triangular prism without specific measurements. However, if we knew the dimensions, we could use the principle that surface area scales with the square of the linear dimensions to compare the two.
Explanation:
To complete the statement about the surface areas of Figure 1 (a square pyramid) and Figure 2 (a right triangular prism), we need to consider how areas scale with the dimensions of the shapes. Salviati's example illustrates that surface areas scale with the square of the linear dimensions, which is an important concept in geometry. Applying this concept to two triangles where one is larger than the other with linear dimensions twice as long, the larger triangle will have an area four times greater (area scales with the square of the linear dimensions).
Correct solution #1: Since the larger triangle's sides are twice as long, its area is 22 = 4 times more than the smaller triangle. If we applied similar reasoning and knew the dimensions of Figure 1 and Figure 2, we could compare their surface areas. However, with the provided information, we cannot definitively complete the given statement about the surface area of the pyramid relative to the prism without the specific measurements of each figure.
By understanding that the surface area of shapes scales with the square of their dimensions and using examples like cutting the larger triangle into four smaller ones (correct solution #2), we can tackle the surface area comparison confidently, provided we have the necessary dimensions.
Priyanka and Ethan were asked to find an explicit formula for the sequence -3,-14,-25,-36,...
Answer:
[tex]a_{n}[/tex] = 8 - 11n
Step-by-step explanation:
These are the terms of an arithmetic sequence with n th term
[tex]a_{n}[/tex] = a + (n - 1)d
where a is the first term and d the common difference
here a = - 3 and
d = - 14 - (- 3) = - 14 + 3 = -11, thus
[tex]a_{n}[/tex] = - 3 - 11(n - 1)
= - 3 - 11n + 11
= 8 - 11n
The explicit formula for the sequence -3, -14, -25, -36, ... is An = -11n + 8.
The student asked for an explicit formula for the sequence -3, -14, -25, -36, and so forth. We notice that each term decreases by 11 from the previous term. To find an explicit formula, we can use the arithmetic sequence formula which is given by An = A1 + (n - 1)d, where An is the n-th term, A1 is the first term, n is the term number, and d is the common difference between the terms.
For the given sequence, the first term A1 is -3 and the common difference d is -11. Substituting these values into the formula, we get An = -3 + (n - 1)(-11). We can simplify this to An = -3 - 11n + 11, which simplifies further to An = -11n + 8. Hence, the explicit formula for the given sequence is An = -11n + 8.
i need to know how long the ramp is
Answer:
20.6
Step-by-step explanation:
Use the trig function Cosine to find the length of the ramp. The cosine function is defined as the ratio adjacent side over hypotenuse. The base 20 is the adjacent side to the angle 14 while the length of the ramp is the hypotenuse. Using the function we write, cos 14 = 20 / x. Solve for x.
Cos 14 = 20 / x
x*Cos 14 = 20
x = 20 / cos 14

Mrs. Jenkins just finished grading her math tests. The average score on her test was 93%. However, she forgot to grade Billy's paper. Billy scored 80% on the test. What is going to happen to the class average, once she includes Billy's score?
A.
The class average will stay the same.
B.
The class average will go up.
C.
The class average will go down.
D.
There is not enough information.
Including Billy's score of 80% will lower the class average from 93% because his score is below the initial average.
Explanation:When including Billy's test score of 80% into the class average that was previously 93%, the class average will definitely go down. This is because Billy's score is lower than the class average, so when it is factored into the overall calculation, it will decrease the average. Hence, the correct answer to the question is: C. The class average will go down.
The range of the set of data below is 9
7. 16, 8, 16, 14, 10, 9, 8, 11, 12, 13, 18
True
False
False, The claim that the range of the data set (16, 8, 16, 14, 10, 9, 8, 11, 12, 13, 18) is 97 is false. The actual range is the difference between the largest and smallest values, which is 10.
The task is to determine whether the statement that the range of the provided data set is 97 is true or false. First, let's define the range. It is the difference between the smallest and largest numbers in a data set. Looking at the data provided: 16, 8, 16, 14, 10, 9, 8, 11, 12, 13, 18, we find the smallest value to be 8 and the largest to be 18.
To calculate the range, we subtract the smallest number from the largest: 18 - 8 = 10. Consequently, the initial claim that the range is 97 is false. The correct range of this data set is, in fact, 10.
The given statement the range of the set of data below is 9 is false.
The correct answer is False.
To find the range of a set of data, we subtract the smallest value from the largest value.
Step 1: Identify the smallest and largest values in the data set.
Smallest value: 7
Largest value: 18
Step 2: Calculate the range.
Range = Largest value - Smallest value
Range = 18 - 7
Range = 11
Step 3: Compare the calculated range with the given range.
Given range = 9
Calculated range = 11
Since the calculated range (11) does not match the given range (9), the statement "The range of the set of data below is 9" is False.
The range of a data set measures the spread or dispersion of the data. It is calculated by finding the difference between the largest and smallest values in the data set. In this case, the smallest value is 7 and the largest value is 18. Therefore, the range is 18 - 7 = 11. This contradicts the given range of 9, making the statement false. In summary, the correct answer is False, and the range of the given data set is 11.

The following equation is being multiplied by the LCD. Complete the multiplication to eliminate the denominators
x+2/3x - 1/x-2 = x-3/3x
(3x)(x-2) [x+2/3x - 1/x-2] = (3x)(x-2) [x-3/3x]
The resulting equation is
x+2-1 = x-3
3x(x+2)-(x-2) = x-3
(x-2)(x+2)-1 = (x-3)(x-2)
(x-2)(x+2)-3x=(x-2)(x-3)
After multiplying by the LCD, the denominators are eliminated, resulting in the equation (x-2)(x+2) - 3x = (x-2)(x-3). Further simplifying this equation, we obtain x^2 - 3x - 4 = x^2 - 5x + 6 which can then be solved with algebraic methods.
Explanation:To solve the given equation by multiplying each term by the lowest common denominator (LCD), which is 3x(x-2), we need to eliminate the fractions first.
The given equation is:
(x+2)/(3x) - 1/(x-2) = (x-3)/(3x)
After multiplying each term in the equation by the LCD, we have:
3x(x-2) * ((x+2)/(3x)) = (x-2)(x+2)3x(x-2) * (-1/(x-2)) = -3x3x(x-2) * ((x-3)/(3x)) = (x-2)(x-3)Now, we can write the new equation without denominators:
(x-2)(x+2) - 3x = (x-2)(x-3)
Next, we simplify it:
x^2 + 2x - 2x - 4 - 3x = x^2 - 3x - 2x + 6
x^2 - 3x - 4 = x^2 - 5x + 6
This equation can now be simplified or solved using algebraic methods such as combining like terms or moving all terms to one side in preparation for factoring or applying the quadratic formula.

How many times greater is the value of 0.03 than the value of 0.003
Answer:
The answer .03 is 10 times greater than .003
Step-by-step explanation:
.003 x 10= .03
Final answer:
The value of 0.03 is ten times greater than the value of 0.003. This is evident by observing that 0.03 is expressed as 3 x 10^-2 while 0.003 is expressed as 3 x 10^-3, showing 0.03 is one decimal place to the left of 0.003.
Explanation:
The value of 0.03 is ten times greater than the value of 0.003. This conclusion is reached by observing the placement of the decimal point. For each power of ten we move to the right, the number becomes 1/10 the size of the previous number. Conversely, moving one place to the left (making the number ten times bigger), we increase the value of the number by a factor of 10.
Expressing these numbers with negative exponents, we have:
0.03 as 3.0 x 10-2 (three and zero tenths times ten to the negative second power)0.003 as 3.0 x 10-3 (three and zero tenths times ten to the negative third power)As illustrated above, since 10-3 is one factor of 10 smaller than 10-2, the value 0.03 is ten times greater than 0.003.

A target with a diameter of 14cm has 4 scoring zones by concentric circles. The diameter of the center circle is 2 cm. The width of each ring is 2 cm. A dart hits the target at a random point. Find the probability that it will hit a point in the outer (yellow) ring
Answer:
[tex]48.98\%[/tex]
Step-by-step explanation:
we know that
The probability that it will hit a point in the outer (yellow) ring is equal to divide the area of the yellow ring by the total area of the target
step 1
Find the area of the yellow ring
[tex]A=\pi [7^{2} -5^{2}][/tex]
[tex]A=24\pi\ cm^{2}[/tex]
step 2
Find the total area of the target
[tex]A=\pi [7^{2}][/tex]
[tex]A=49\pi\ cm^{2}[/tex]
step 3
Find the probability
[tex]24\pi/49\pi=0.4898[/tex]
Convert to percentage
[tex]0.4898*100=48.98\%[/tex]
Answer:
0.38468
Step-by-step explanation:
To know the probability we need to know the area of the yellow zone and the area of the rest. So, the yellow circle (that contains white, red and blue circle) has a radius of 1+2+2+2=7. Then the area is
Area yellow= [tex]\pi r^{2}= \pi *7^{2}=49\pi.[/tex]
But, the yellow zone is yellow circle - blue circle.
Area blue = [tex]\pi r^{2}= \pi *(1+2+2)^{2}=\pi *5^{2}=25\pi.[/tex]
Then, the yellow zone will be [tex]49\pi-25\pi=24\pi.[/tex]
Area target= 14*14 = 196.
So, the probability is the yellow zone divided by the target (total area):
P = [tex]\frac{24\pi}{196}= \frac{6\pi}{49}= 0.38468.[/tex]
