Step-by-step explanation:
Think about how many steps per minute Paul can walk. Knowing that he can walk 15 steps in 5 minutes, we can say that Paul can walk 3 steps/minute.
We're asked to figure out how many minutes it would take him if he walks at a constant speed if he takes 75 steps. So we can just divide 75 steps into 3 steps/minute and then we should get 25 minutes!
Answer:
25 Minutes.

Its hard to explain.
Question 3
Juvenile ground squirrels respond to predators by making alarm calls that can alert others to danger. A biologist conducted a study to investigate how squirrels respond to these alarm calls: run
to burrow or freeze. The biologist played recordings of alarm calls for three samples of ground squirrels, grouped by age, and observed the squirrels' responses. The data for the three age levels
are shown in the table.
Run to Burrow
Freeze
Total
21
18
39
16
24

1 to 5 Days Old
6 to 15 Days Old
16 to Zs Days Old
Total

98
If ground squirrels at different ages respond to the alarm signals in the same proportions, what would be the expected count for 6-to 15-day-old squirrels that freeze?
Answer:
((19)(49)/98)
Step-by-step explanation:
Answer: C ((40)(49)/98)
Step-by-step explanation: The formula for expected count is (row total)(column total)/table total

Answer:
9
Step-by-step explanation:
15.25-8.50= 6.75, 6.75÷.75=9
Answer:
9 fountain drinks
Step-by-step explanation:
8.50+0.75x=15.25 is the equation you will use. 8so is your starting point and for every drink you get, it is 75 cents.
Solve by subtracting 8.50 from 15.25
0.75x=6.75
Divide 6.75/0.75 to isolate the x.
x=9

A bird is flying at an altitude of 400 feet and descending to its nest located in a tree 20 feet above the ground. The angle from the nest to the bird is 24 degrees. Approximately how far is the bird from the nest.
ANSWER:
The answer is 934 If you make a right triangle with 380 as the height because the bird has 380 ft to go until the nest then you make the angle 24 opposite to that side. After you use sin to find the missing side which is 380/x= sin24 the answer you get is rounded.
Answer:T he bird will land at a radios of 20 feet in th air.
Step-by-step explanation: The object is falling 380 feet out of the air out of 400.

Mike has attempted 84 free throws. Of those attempted,
63 have gone in the basket. Based on this rate, what is the
probability that Mike's next free throw attempt will go in
the basket?
Answer:
63 ÷ 84 = 0.75 // 75% // 3/4
Step-by-step explanation:
63 divided by 84 equals 0.75, 75%, or 3/4. meaning the probability of Mike making his next free throw 75%
1 Professor Peterson is buying a writing
desk. The width of the desk must be less
than 4 ft.
HELP
The inequality of the width of the desk must be less than 4 ft is w < 4.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
Inequalities are mathematical statements that compare two expressions using symbols like "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "!=" (not equal to).
In this case, the problem states that the width of the desk must be less than 4 ft.
We can use the symbol "<" to indicate that the width (w) is smaller than 4 feet. Therefore, we can write the inequality as w < 4, which means that any value of w that is less than 4 feet satisfies the given condition.
Thus,
The width of the desk must be less than 4 ft is w < 4.

Step-by-step explanation:
_______ is the amount of space________ a two-dimensional shape. It can be measured in units such as_______ or _________
Answer:
Area; inside; centimeters; meters.
Step-by-step explanation:
Area is the amount of space inside a two-dimensional shape. It can be measured in units such as centimeters or meters.
In Mathematics, it is typically used to measure the amount of space contained in two-dimensional shapes such as a square, rectangle, circle, sphere, etc.
Consider the area of the following shapes;
I. The area of a circle = πr²
Where, r is the radius of the circle.
II. Area of square = L²
Where, L is the length of its sides.
III. Area of rectangle = Length * width.
Answer:
Area; inside; centimeters; meters.
Step-by-step explanation:
Area is the amount of space inside a two-dimensional shape. It can be measured in units such as centimeters or meters.
Four runners are training for long races. Noah ran 5.123 miles, Andre ran 6.34 miles, Jada ran 7.1 miles, and Diego ran 8 miles.
a. What is the total running distance of the four runners?
b. Jada ran how much farther than Noah?
Answer:
26.56300 1.97700
Step-by-step explanation:
You add up all of them which was 26.5630 then you do 7.1-5.123+1.97700
Answer:
a. 26.563 milesb. 1.977 milesStep-by-step explanation:
Given,
Distance Noah ran = 5.123 miles
Distance Andre ran = 6.34 miles
Distance Jada ran = 7.1 miles
Distance Diego ran = 8 miles
Hence,
a. Total running distance of four runners
= (5.123 + 6.34 + 7.1 + 8) miles
= 26.563 miles (Ans)
b. Distance more ran by Jada than Noah
= (7.1 - 5.123) miles
= 1.977 miles (Ans)

D It represents the probability that a student in Mr. Lopez's classes does not have chores and does not receive an allowance.
Step-by-step explanation:
The significance level, also denoted as alpha or α, is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference

Physical and emotional healthA tank contained 80 liters of water. The function “w” represents the relationship between “t”, time in minutes, and the amount of water in the tank in liters. The equation w(t) = 80 - 2.8t defines this function. How would the graph of the inverse function of compare to the graph of “w”? PLEASE HELP!!
w(t) tells you the amount of water w at a given time t.
The inverse function tells you at which time t the tank contains an amount of water w.
To get the inverse function, solve the equation
w = 80 - 2.8t
for t :
w = 80 - 2.8t
2.8t = 80 - w
t = (80 - w) / 2.8
t ≈ 28.57 - 0.357 w
The graph of w(t) is a downward-sloping line. The graph of the inverse is also a downward-sloping line, but its intercept (28.57) and slope (-0.357) are both smaller than the intercept and slope of w(t).

A map says that 4 centimeters represents 10 kilometers. What is the real distance that 18 centimeters represents?
Answer:
The real distance that 18 centimeters represent is 45 kilometers.
Step-by-step explanation:
In this case, you can use a rule of three to find the real distance that 18 centimeters represent given that 4 centimeters represent 10 kilometers:
4 cm → 10 km
18 cm → x
x=(18*10)/4
x=45 km
According to this, the answer is that the real distance that 18 centimeters represent is 45 kilometers.

Please include an equation.
Answer:
12
Step-by-step explanation:
Answer:
9 kids tickets
Step-by-step explanation:
Let k = no. of kid's tickets
12 - k = no. of adult's tickets
9.50(12 - k) + 6.50k = 87
95(12 - k + 65k = 870
1140- 95k + 65k = 870
- 30k = -270
k = 9 kids
