Answer:
Ok so what it is asking on part A is if your driving 50% on the highway which is 30 miles a gallon and 50% on around the town which is 25 miles a gallon then how many miles a gallon are you getting and the answer for that you need to first find what kind of problem it is and in this case you are working with percents so what you first want to do is multiply 50% to both 30 and 25 which will be 15 and 12.5 then add those together to get you answer now do the same for part B but instead of 50% it will be 60% and 40%.

Is the area of a square with side length 2 inches greater than or less than the area of a circle with radius 1.2 inches?
Answer:
less
Step-by-step explanation:
We can answer the question about relative sizes of a square and a circle by finding the area of each.
__
The area of the square is ...
A = s²
A = (2 in)² = 4 in²
The area of the circle is ...
A = πr²
A = π(1.2 in)² = 1.44π in² ≈ 4.524 in²
The area of the square is less than the area of the circle.
_____
Additional comment
The area of a circle is π/4 times the area of the square in which it is inscribed. If the diameter of the circle is 1.2 times the side length of the square, its area ratio to the square will be (1.2²)(π/4) = 0.36π ≈ 1.13. That is, the circle is larger and the square is smaller.

There are 10 pink balls out of 20. (add all the numbers together)
So that means there is a 10/20 chance to get a pink ball.
Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
So, the probability is the number of favored outcomes/ number of possible outcomes.
In this case, the favored outcomes is pink, which is 10.
The number of possible outcomes is 2+1+10+2+5 = 20
This gives us 10/20, which is 1/2 when simplified
The graph shows how much insulin, in micrograms (mcg), is in a patient's body after receiving an injection. Write an equation giving the number of mcg of insulin, `m`, in the patient's body h hours after receiving the injection.
By using the first two points on the graph, we conclude that exponential equation is:
y = 200*(0.4)^t
What is the equation?We assume that the equation is an exponential decay of the form:
y = A*(r)^t
When t = 0 we have:
y = A
On the graph we can see that the initial value is 200, then A = 200, so we have:
y = 200*(r)^t
By looking at the graph we can see that:
80 = 200*(r)^1 (this is the second point graphed).
Solving for r we get:
80 = 200*(r)
80/200 = r = 0.4
Then the exponential equation is:
y = 200*(0.4)^t

The company also wants to offer a family size box of cereal. The family size box will be a dilation of the single serving 1. 2-ounce box. It must contain 18. 75 ounces of cereal. What scale factor does the company need to use for the family size box?.
Answer:
2.5
Step-by-step explanation:
The relative volumes of the two similar boxes will be related by the cube of the dilation factor. That means the dilation factor (d) satisfies ...

What is Y + 4 = -3 (x +1) in standard form?
Answer:
-3x - y = 7
first, distribute -3:
y + 4 = -3x - 3
then get x and y on the same side and the number on the other side for standard form.
add 3 to both sides:
y + 7 = -3x
subtract y from both sides:
7 = -3x - y

The graph shows the distance covered by a runner after a given number of hours.
The runner travels
✔ 8
miles in 2 hours.
The runner’s speed is
miles per hour
If the runner travels 8 miles in 2 hours then the speed of the runner is 4 miles per hour.
The runner traveled 8 miles in 2 hours.
To find the runner's speed, we can use the formula:
Speed (in miles per hour) = Distance / Time
In this case, the distance is 8 miles and the time is 2 hours:
Speed = 8 miles / 2 hours
= 4 miles per hour
So, the runner's speed is 4 miles per hour which means that the runner covers a distance of 4 miles for every hour they run.

( How far does the tip of the minute hand of a clock move in 20 minutes if the hand is 5 inches long
Answer:
3 1/3 pi inches
Step-by-step explanation:
since we know that when 20 minutes have passed, the minute hand will have moved 4 intervals (i.e. from 12 to 4), and each interval is 30 degrees by measurement. So 4 intervals have a degree measurement of 120 degrees, which is 1/3 of the whole circle (clock). since there isn't any notation on whether pi is taken as 3.14 or 22/7 or whatsoever, you can just say that it has moved (5x2)pi x 1/3 = 3 1/3 pi inches
