A circle has a diameter of 30 yd. What is it’s circumference?
Use 3.14 for PIE, and don’t your answer.
Circumference of the circle = 94.2 yd
Solution:
Given data:
Diameter of the circle = 30 yd
The value of π = 3.14
To find the circumference of the circle:
Circumference of the circle = πd
Substitute the diameter value in the formula, we get
Circumference of the circle = 3.14 × 30
= 94.2
Circumference of the circle = 94.2 yd
The length of a certain rectangle is 15cm more than three times its width. If the perimeter of the rectangle is 94cm, what is the area.
Answer:
Step-by-step explanation:
Let w be the width
Length = 3w +15
Perimeter = 94 cm
2*(length + width) = 94
2*(3w+15 + w) = 94
2*( 4w + 15) = 94
4w + 15 = 94/2
4w +15 = 47
4w = 47 -15
4w = 32
w = 32/4
w = 8 cm
Length = 3w +15 = 3*8 + 15 = 24 +15 = 39
Length = 39cm
Area = length * width = 39*8 = 312
Area = 312 cm²
The area of the rectangle is [tex]\( \boxe{312 \, \text{cm}^2} \).[/tex]
Step 1
Let's denote the width of the rectangle as w cm.
According to the problem, the length of the rectangle is [tex]\( 15 \)[/tex] cm more than three times its width. So, the length [tex]\( l \)[/tex] can be expressed as [tex]\( 3w + 15 \)[/tex]cm.
The perimeter P of a rectangle is given by:
[tex]\[ P = 2(l + w) \][/tex]
Given that the perimeter of the rectangle is [tex]\( 94 \)[/tex] cm, we can write the equation:
[tex]\[ 94 = 2((3w + 15) + w) \][/tex]
Step 2
Now, let's solve for [tex]\( w \)[/tex]:
[tex]\[ 94 = 2(4w + 15) \]\[ 94 = 8w + 30 \]\[ 8w = 94 - 30 \]\[ 8w = 64 \]\[ w = \frac{64}{8} \]\[ w = 8 \][/tex]
Step 3
Now that we have found the width of the rectangle to be [tex]\( 8 \)[/tex] cm, we can find its length:
[tex]\[ l = 3w + 15 \]\[ l = 3(8) + 15 \]\[ l = 24 + 15 \]\[ l = 39 \][/tex]
Step 4
Now that we have the width [tex]\( w = 8 \)[/tex] cm and the length [tex]\( l = 39 \)[/tex] cm, we can calculate the area A of the rectangle:
[tex]\[ A = l \times w \]\[ A = 39 \times 8 \]\[ A = 312 \][/tex]
So, the area of the rectangle is [tex]\( \boxe{312 \, \text{cm}^2} \).[/tex]
The probability
The number of three-digit numbers with distinct digits that can be formed using the digits 1, 2, 3,5,8, and 9 is _. The probability that both the first digit and the last digit of the three-digit number are even numbers is _.
Probability of distinct 3-digits is 1/6.
Probability of both the first digit and the last digit are even numbers is 1/5.
Step-by-step explanation:
Given set of numbers {1,2,3,5,8,9} = 6
Total number of 3-digits can be formed = 6[tex]\times[/tex]5[tex]\times[/tex]4 = 120.
Probability of the three-digit numbers with distinct digits :
The number of 3-digit numbers with distinct digits = (6[tex]\times[/tex]5[tex]\times[/tex]4) / (3[tex]\times[/tex]2[tex]\times[/tex]1) = 20.
P(distinct 3-digits) = no. of distinct 3-digits / Total no.of 3-digits
⇒ 20/120
⇒ 1/6
Probability that both the first digit and the last digit of the three-digit number are even numbers :
The even numbers in the set are 2 and 8 = 2 possibilities.
The number of 3-digits with 1st and 3rd digit are even = (2[tex]\times[/tex]6[tex]\times[/tex]2) = 24.
P(1st and 3rd digits even)= no. of 1st and 3rd digit even/Total no. of 3-digits.
⇒ 24/120

Look at the following graph of the given equation. Determine whether the equation is a function. Explain why or why not.
y= 2x+2
+ • 2.6)
+ (1.4)
(0.2)
The equation [tex]y=2x+2[/tex] is a function
Explanation:
Given that the graph contains the coordinates [tex](-1,0)[/tex], [tex](0,2)[/tex] , [tex](1,4)[/tex] and [tex](2,6)[/tex]
We need to determine whether the equation [tex]y=2x+2[/tex] is a function.
To determine the equation is a function, let us substitute the coordinates in the equation and check whether it satisfies the equation.
Let us substitute the coordinate [tex](-1,0)[/tex] in the equation [tex]y=2x+2[/tex]
Thus, we have,
[tex]0=2(-1)+2[/tex]
[tex]0=-2+2[/tex]
[tex]0=0[/tex]
Thus, the coordinate [tex](-1,0)[/tex] satisfies the equation [tex]y=2x+2[/tex]
Substituting the coordinate [tex](0,2)[/tex] in the equation, we have,
[tex]2=2(0)+2[/tex]
[tex]2=2[/tex]
Thus, the coordinate [tex](0,2)[/tex] satisfies the equation [tex]y=2x+2[/tex]
Substituting the coordinate [tex](1,4)[/tex] in the equation [tex]y=2x+2[/tex]
[tex]4=2(1)+2[/tex]
[tex]4=4[/tex]
Thus, the coordinate [tex](1,4)[/tex] satisfies the equation [tex]y=2x+2[/tex]
Substituting the coordinate [tex](2,6)[/tex] in the equation, we get,
[tex]6=2(2)+2[/tex]
[tex]6=6[/tex]
Thus, the coordinate [tex](2,6)[/tex] satisfies the equation [tex]y=2x+2[/tex]
Hence, the coordinates [tex](-1,0)[/tex], [tex](0,2)[/tex] , [tex](1,4)[/tex] and [tex](2,6)[/tex] satisfies the equation [tex]y=2x+2[/tex]
Thus, the equation [tex]y=2x+2[/tex] is a function.

which expression is equivalent to 5^3 select all that apply
a. 5^7 x 5^-4
b. 5^12/5^4
c. 5^1 + 5^2
d. 5^0 x 5^3
e. 5^3 - 5^0
Expressions a, b, and d are equivalent to 5^3. They all follow the laws of exponents, resulting in the same value of 5^3, or 125.
Explanation:The question is asking which expressions are equivalent to 5^3. Let's break down each option:
a. 5^7 x 5^-4: Utilizing the law of exponents, we add the exponents when multiplying the same base, hence we get 5^3. b. 5^12/5^9: According to the law of exponents, we subtract the exponent of the denominator from the exponent of the numerator, which gives us 5^3. c. 5^1 + 5^2: This equals 5 + 25, which is not equal to 5^3 (125). d. 5^0 x 5^3: Any number raised to the power 0 is 1, therefore this equals 5^3. e. 5^3 - 5^0: This equals 125 – 1, which is not equal to 5^3 (125).
So, options a, b, and d are equivalent to 5^3.

Answer:
87.92 in²
Step-by-step explanation:
pi × (R² - r²) = area
Where R is the radius of the outer circle and r of the inner circle.
Since C = 2pi×r
37.68 = 2×3.14×r
r = 6 in
R = 6 + 2 = 8 in
Therefore,
pi × (R² - r²) = area
Area = 3.14 (8² - 6²)
= 87.92 in²
Convert 746% to a mixed number
Answer: 373/50
Step-by-step explanation:
Step 1: convert to a fraction
746% = 746 ÷ 100 = 7.46
7.46 = 373/50
Step 2: Write the number as a fraction of one: 7.46 = 746/100
Step 3: use a common divisor of 2 to reduce the numbers, we have
(746÷2)= 373
(100÷2)=50
when reduced to the simplest form= 373/50
Therefore, 746/ 100 = 373/50 when expressed as a mixed number.
Answer: 373/50
Step-by-step explanation:
Step 1) Since 746% is a percent, it is written over the denominator of 100. So first convert it to a fraction, which would be 746/100.
Step 2) Find the GCF (greatest common factor). In order to find the GCF start by writing all the factors of
100:
1, 2, 4, 5, 10, 20, 25, 50, 100
Step 3) Now test every number there and see if any go into 746. Start at the highest number, which in this case is 100. (Example, ask yourself, “does 100 go into 746? No.” Then try with 50, and continue until you get to a number that goes into 746 evenly.)
Step 4) The GCF from the previous step is 2. So now divide 746 by 2 (answer is 373) and 100 by 2 (answer is 50).
Step 5) Now put 373/50 and that’s your answer! Congratulations you finished it!

3. In a carnival game, players are given three darts and throw them at a set of balloons on a wall.
Suppose there are eight balloons on the wall. Five of the eight balloons have slips of paper in
them that say 'Winner' while three of the eight balloons have slips of paper that are blank.
Suppose you pop a balloon with each of your three darts. If all three balloons have 'Winner'slips,
you win the grand prize. If all three balloons have blank slips, you win the consolation prize.
What is the probability that:
a) you win the grand prize?
b) you win the consolation prize?
The chances of winning the grand prize in this game are approximately 0.089, whereas the chances of winning the consolation prize are 0.01.
Explanation:The subject of this question is Probability, which is a branch of Mathematics. To calculate the probability, we'll need to determine the total number of outcomes and the count of the favorable outcomes.
a) To win the grand prize, all three balloons popped have to have 'Winner' slips. The probability of each dart hitting such a balloon will decrease as the total number of balloons decreases. First dart probability would be 5/8 (5 'Winner' balloons out of 8 total), the second one 4/7 (as one 'Winner' balloon is already popped), and 3/6 for the third. Multiply these probabilities together to get the overall probability: (5/8) * (4/7) * (3/6) = 0.089 (rounded to the third digit).
b) Similarly, for the consolation prize, we would have to hit all three balloons with blank slips. The process is equivalent, resulting in a probability of (3/8) * (2/7) * (1/6) = 0.01 (rounded to the third digit).

What size are the intervals on the histogram?
6 4 7 5
To construct a histogram, you must decide on your interval size by dividing the data range by your desired number of intervals. Then, sketch the graph with scaled axes and intervals consistently to accurately represent the data.
Explanation:To construct a histogram, you need to determine the interval size for your bins. The interval size depends on the range of your data and the number of intervals you want to use. For instance, if you have data ranging from 32.5 to 100.5 and you want to create five intervals, you subtract the smallest value from the largest and then divide by the number of intervals. So it would be (100.5 - 32.5) ÷ 5, which equals 13.6. This means each interval would be 13.6 units wide.
When constructing the actual histogram, the x-axis would cover from 32.5 to 100.5 and the y-axis would cover the frequency of the data within each interval. An interval's endpoints can be determined successively by adding the interval width to the previous endpoint, starting with 32.5. Moreover, for data with a small range like 1 to 6, you could create six intervals ranging from 0.5 to 6.5 to ensure all data points are included, with a 1 unit interval size for clarity.
Sketch the graph using a ruler and pencil, and carefully scale the axes to accurately reflect the range and intervals for the data you're representing. Consistency in interval size is key when placing data values into each bin.
Final answer:
A histogram is constructed by determining the number of intervals, with a common range being five to 15 intervals. Calculate the interval width by dividing the total range of data by the chosen number of bins. Use a ruler and pencil for a scaled and precise histogram representation.
Explanation:
To construct a histogram, you need to decide on the number of intervals, also known as classes or bins. In this case, the data provided suggests we need to create five to six intervals. The x-axis for our histogram might range from 32.5 to 100.5, representing the data values, and the y-axis records the frequency of the data points.
To calculate the width of each interval, take the range of the data (100.5 - 32.5 = 68) and divide it by the number of intervals (5). This gives us an interval width of 13.6. When scaling the axes, use a ruler and pencil for precision.
For example, if your data set ranges from a smallest value of 1 to a largest value of 6, you might set your bins to start at 0.5 and end at 6.5 to ensure that all values are included. With this range of 6 (6.5 - 0.5), and deciding on six bins, the bin size or interval size would be 1. This is explained in Solution 2.10.
Remember to consistently apply the same method when placing data values within intervals to enable comparability and clarity in your histogram.
