Which expression can be used to determine the slope of the linear function represented in the table? x 0 4 y 5 9
a 9-5 over 4-0
b 4-0 over 9-5
c 5-0 over 9-4
d 9-4 over 5-0
Answer:
a) 9-5 over 4-0 is the CORRECT OPTION.
Step-by-step explanation:
Here, according to the given information:
x 0 4
y 5 9
⇒ when x = 0, y = 5 or (0,5) is a given point on function.
and when x = 4, y = 9 or (4,9) is a given point on function.
Now, if two such points (a,b) and (c,d) are given, then the slope S is given as:
[tex]S = (\frac{d-b}{c-a} )[/tex]
So, here taking (a,b) and (c,d) as (0,5) and (4,9):
[tex]S = (\frac{9-5}{4-0} )[/tex]
Hence, 9-5 over 4-0 is the CORRECT OPTION.
Answer:
The answer is the first option 9-5/4-0

You need to fill a water jug with 5.85 L. You filled it with 2.45 L and then added 2.84 L more. How much more water do you need
The amount of water already in the jug is 5.29 L. To fill the jug up to 5.85 L, 0.56 L more water is needed.
Explanation:This is a simple arithmetic problem involving addition and subtraction. Given that you need to fill a jug with 5.85 L of water, you have already filled it with 2.45 L and then added 2.84 L more. The total amount of water in the jug now can be found by adding these two amounts together, giving 2.45 L + 2.84 L = 5.29 L. To find out how much more water you need, subtract this amount from the total capacity of the jug: 5.85 L - 5.29 L = 0.56 L. Therefore, you need 0.56 L more water to fill the jug.

Can someone please give me the correct answer.
Answer:
B
Step-by-step explanation:
The graph shows "days" in the x-axis and "cost" in the y-axis.
It says he left the car at airport for 5 days, so we need to find the cost he paid for 5 days.
We have to look at "5" in the x-axis. There is 4 and 6 given, so 5 would be between these two numbers. Now, from x = 5, we draw an imaginary straight line upwards towards the red line. That will approximately cross a little over $24 but a little lower than $30.
So, the cost would be between 24 and 30, but closer to 24.
From the answer choices, we can clearly see that this will be $26.00, answer choice B is right.
what is quotient of 6 1/4 divided by 5/8
Answer: The quotient = 10
Step-by-step explanation: A quotient is the result you get when a number is used to divide another number. e . g.
6¹/₄ ÷ ⁵/₈ ( where 5/8 is the divisor )
First convert 6¹/₄ to improper fraction
= 25/4 ÷ 5/8
= 25/4 × 5/8
= 10
The quotient = 10.
NOTE: The 5/8 changed to 8/5 because when dividing fractions, immediately you applied the multiplication symbol, the denominator of the divisor becomes the numerator and vice versa
Suppose that y varies directly with x and inversely with z, and y = 20 when x = 15 and z = 3. Write the equation that models the relationship. Then find y when x = 6 and z = 6.
Answer: y = 4x/z , y = 4.
Step-by-step explanation:
Recall ; from Variation,
y ∞ x ----------------------------- 1
y ∞ ¹/z ---------------------------2
Now , combine equation 1 & 2 together, it metamorphosed to
y = kx/z -------------------------- 3
Remember, k is a constant and the value must be find first
K = yz/x
= (20 x 3) /15
= 4
To get the equation that models the relationship, we substitute for k in equation 3
y = 4x/z.
To find the value of y , substitute for the values of k, x and z
y = ( 4 x 6 )/6

A baseball player throws a ball from second base to home plate. How far does the player throw the ball?
Round your number to the nearnest tenth.
Answer: _______ ft
Answer:
The player throws 127.3 ft from second base to home plate.
Step-by-step explanation:
Given:
Distance from home to first base = 90 ft
Distance from first base to second base = 90 ft
We need to find the distance from second base to home.
Solution:
Now we can assume the complete scenario to be formed as a right angled triangle with two sides given and to find the third side.
Now by using Pythagoras theorem which states that;
Square of the hypotenuse side is equal to sum of squares of other two sides.
framing in equation form we get;
distance from second base to home = [tex]\sqrt{90^2+90^2}= 127.27 \ ft[/tex]
Rounding to nearest tent we get;
distance from second base to home = 127.3 ft
Hence The player throws 127.3 ft from second base to home plate.
The distance from second base to home plate is calculated using the Pythagorean theorem because it's the diagonal of the square formed by the bases, which are 90 feet apart. The resulting diagonal (hypotenuse) is approximately 127.3 feet, rounding to the nearest tenth.
Explanation:The question seems to imply that the distance is known in the context of a standard baseball diamond, but unfortunately, it has not provided us with the exact distance from second base to home plate. However, if we refer to the standard dimensions of a baseball field, the distance from home plate to second base is not a straight line but the diagonal of a square formed by the bases. Each base in professional baseball is 90 feet apart, so to find the distance from second base to home plate, which is the hypotenuse of the square (assuming perfect square dimensions), we would use the Pythagorean theorem.
Using the theorem a² + b² = c², where 'a' and 'b' are the sides of the square (90 feet each) and 'c' is the hypotenuse (distance from second base to home plate), we can calculate:
a² = b² = 90²
Therefore,
c² = 90² + 90² = 8100 + 8100 = 16200
Then, solving for 'c' gives us:
c = √16200 ≈ 127.3 feet
So the baseball player throws the ball approximately 127.3 feet from second base to home plate, rounding to the nearest tenth.

a rectangular parking lot has an area of 7/10 square kilometer the width is 1/3 kilometer what is the length of the parking lot written as an improper fraction in kilometers
Answer:
[tex]2\frac{1}{10}[/tex] km
Step-by-step explanation:
We are given;
The are of a rectangle as 7/10 km²Width of the rectangle is 1/3 kmWe are required to find the length of the rectangle;
We need to know how to find the area of a rectangle first;
Area of rectangle = Length × Width
Rearranging the formula;
Length = Area of rectangle ÷ Width
= 7/10 km² ÷ 1/3 km
We get;
[tex]=\frac{7}{10} *\frac{3}{1}[/tex]
[tex]=\frac{21}{10}[/tex]
[tex]=2\frac{1}{10} km[/tex] (improper fraction)
Thus, the length of the rectangular park is [tex]2\frac{1}{10}[/tex] km
The length of the parking lot is 21/10 kilometers. This is found by rearranging the formula of the rectangular area to solve for length, substituting the given values and simplifying.
Explanation:The problem is about finding the length of a rectangle when we know the area and the width. The formula of the area for a rectangle is the product of its length times its width. In this case, the area of the parking lot is 7/10 square kilometers and the width is 1/3 kilometers. The formula becomes: Area = Length * Width .
From this we can solve for length by dividing the area by the width, thus: Length = Area / Width. Substituting the values, we get: Length = (7/10) / (1/3), which simplifies to Length = (7/10) * (3/1) = (21/10) km.
So the length of the parking lot is 21/10 kilometers, or 2.1 kilometers written in decimal form.

y = 4x - 10 is the equation of line with slope of 4 and passes through the point (5, 10)
Solution:
A line has a slope of 4 and passes through the point (5, 10)
The equation of line in slope intercept form is given as:
y = mx + c -------- eqn 1
Where, "m" is the slope of line and "c" is the y - intercept
Given that, Slope = m = 4
The line passes thorugh (5, 10)
Substitute m = 4 and (x, y) = (5, 10) in eqn 1
10 = 4(5) + c
10 = 20 + c
c = -10
Substitute c = -10 and m = 4 in eqn 1
y = 4x - 10
Thus the equation of line in slope intercept form is found

The radius of a circle is 13cm .a chord is a distance of 5cm from the centre.the length of the chord is ?
Answer:
24 cm
Step-by-step explanation:
The triangle formed by the chord, its bisector, and a radius is a right triangle with hypotenuse 13 and one side of length 5. These are two of the numbers in the 5-12-13 Pythagorean triple, so we know that half the chord has length 12.
The chord is 24 cm long.
_____
In case you haven't memorized some of the more commonly used Pythagorean triples, you can find the half-chord length (h) using the Pythagorean theorem:
13² = 5² + h²
169 -25 = h²
√144 = h = 12
The half-chord length is 12, so the full chord length is 24 centimeters.

there are are also purple marbles in the bag. which of the following can not be the probability of randomly selecting a purple marble from the bag ?
a. 1/10
b. 1/5
c. 2/5
d. 7/15
(please give an explanation)
Answer: d
Step-by-step explanation:
The probability of not being purple is the probability of the three other colors. Suppose the number of purple marbles is x. Then we have 20+30+40+x = 90 + x marbles. Then the probability of not being purple is 90/(90+x). If this fraction can have a lowest term for some value of x, then the numerator of this lowest term must be a factor of 90.
Checking through the options, only option D has a non-factor of 90 as its numerator.
The probability of randomly selecting a purple marble from the bag can be determined by dividing the number of purple marbles by the total number of marbles in the bag. Option a, 1/10, cannot be the correct probability value.
Explanation:In order to determine which probability value cannot be correct, we need to find the total number of marbles in the bag and subtract the number of white, black, and beige marbles from it. The remaining number will represent the number of purple marbles in the bag. Then, we can find the probability of randomly selecting a purple marble by dividing the number of purple marbles by the total number of marbles in the bag.
Total number of marbles = white + black + beige + purple = 20 + 30 + 40 + purple
Total number of marbles = 90 + purple
Now, we can check which of the given probability values cannot be correct:
Probability = 1/10 = purple/(90+purple) Probability = 1/5 = purple/(90+purple) Probability = 2/5 = purple/(90+purple) Probability = 7/15 = purple/(90+purple)
Let's solve each equation to find the value of purple:
purple = (1/10) * (90 + purple) purple = (1/5) * (90 + purple) purple = (2/5) * (90 + purple) purple = (7/15) * (90 + purple)
Solving these equations, we find that the probability values given in options b, c, and d are all possible probabilities. Therefore, the correct answer is option a, 1/10, which cannot be the probability of randomly selecting a purple marble from the bag.
