distance = time * speed
1 mile = time * 3.5 miles /56 minutes
so time = 56 minutes/3.5 = 16 minutes
6. The answer is A. 3 - 3x
7. The answer is C. -30
8. The answer is B. -11
9. Believe the answer is B. 7xy
10. The answer is A. 48
To solve this problem you you would use 3.14 and multiply it by your radius squared, then multiplied by 4. You would end up getting 452ft cubed.
The probability illustrated shows that the
percent of cookies would have between 13.8 and 24.2 chips is 95.44%.
<h3>How to calculate the probability?</h3>
It is important to note that the requirement to solve the probability between z-values is to know that the probability between the z-values is the difference between the probability of the greatest z-value and the lowest z-value.
This will be illustrated thus:
Z value for 13.8, z =(13.8-19)/2.6 =-2
Z value for 24.2, z =(24.2-19)/2.6 = 2
P( 13.8<x<24.2) =P(-2<z<2)
=P( z <2 –P(z < -2)
=0.9772 -0.0228
=0.9544
= 95.44%
The percent is 95.44%.

There is an error in the equation provided. Looking at other similar question such as this, I think the equation related to x and y should be 90x + 1600 = y
Answer:
a) 90
b) 1600
Step-by-step explanation:
The equation 90x + 1600 = y is an equation of a straight line in the form y = mc + c
Adjusting the equation to the general form we get
y = 90x + 1600
m = 90
c = 1600
a) the change in Mary's total pay for each copy she sells in this case is referring to the change of y to the change of x.
In other word, it is the slope of the function.
m = 90
b) if Mary didn't sell any copies, the value of x will be 0.
In graph of a straight line, the value when x= 0 is at the value of y-intercept,
c = 1600
