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.

Tickets to the movies cost $9.50 for adults and $6.50 for kids. A large group bought 12 tickets and spent a total of $87. How many kid's tickets did the group purchase?
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

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%
Can someone please help me with this....im stuck.
Answer:
Step-by-step explanation:
One clue about where to start is this: the sentence describes the length by referring to the width. "The LENGTH is blah, blah, blah, the WIDTH. When that happens, choose a variable to represent the width (the quantity being referred to).
Width = w
Length IS three more than (added to) 4 times (multiplied by) the width
Length = 4w + 3
Area of a rectangle is the width multiplied by the length.
Equation: w(4w + 3) = 24
Solve.
Multiply out the left side.
4w^2 + 3w = 24
Subtract 24.
4w^2 + 3w -24 =0
This equation does not factor. Use the Quadratic Formula. One of the solutions is a negative number, so that should be rejected (width can't be a negative number).
[tex]w=\frac{-3+\sqrt{393}}{8}[/tex]
Substitute this into the expression 4w + 3 to find the length. A calculator can give you decimals for both dimensions.
PLEASE HELP!!!! While observing the fare meter in a taxi, a student records the following data:
Reading on Taxi Fare Meter
Time (minutes) Meter Reading
0 $7.75
10 $13.25
20 $18.75
30 $24.25
What is the equation that relates the cost, C(t), of the taxi ride and time, t, in minutes? What is the cost of a 42-minute taxi ride? (7 points)
C(t) = 0.55t + 7.75, $30.85
C(t) = 1.71t + 7.75, $79.57
C(t) = 0.775t + 5.50, $38.05
C(t) = 5.5t + 0.775, $231.78
Answer:
C(t) = 0.55t + 7.75, $30.85
Step-by-step explanation:
the fixed cost is $7.75. this is the cost incurred at zero minutes of the taxi ride
the variable cost or the cost per minutes driven =
(13.25 - 7.77) / (10 - 0) = 0.55
total cost = 7.75 + 0.55t
cost of 42 minutes = 7.75 + 0.55(42) = $30.85

3x + 5y = 20
What is the solution (x,y) of the system of equations?
Answer:
X=10
Y=-2
Step-by-step explanation: The value of X is given therefore you use it to find the value of Y in the equation:
3(10)+5y=20
5y=20-30
5y=-10
5y/5=-10/5
5 is cancelled out leaving y=-2

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)
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.

_______ 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.

Find the ordered pair that is a member of both -2x + 6y = 34 and
2x + 2y = 14 or indicate if it does not exist or there are infinite
possibilities.
Answer:
(1, 6) is the solution
Step-by-step explanation:
-2x + 6y = 34
2x + 2y = 14; divide by 2
x + y = 7; subtract x
y = 7 - x
let's substitute y with 7 - x in first equation
-2x + 6*(7 - x) = 34; expand multiplication
-2x + 6*7 - 6*x = 34; group
-8x + 42 = 34; subtract 42
-8x = 34 - 42 = -8; divide by -8
x = 1
y = 7 - 1 = 6
It is the only solution, as we've arrived at exact numbers.

Question is incomplete :
It costs $4 to go to the swimming pool
The cost of n visits =
Membership at the pool costs $21. Members pay $3 each time. WHAT is The cost for a member to swim including membership fee?
What is the difference between the cost of 15 visits with and without a membership?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Swimming cost = $4
Cost of swimming n Times = cost per swim * number of swims
= $4 * n
= $4n
Membership cost = $21
Cost per swim for members = $3
Swimming cost including membership fee :
21 + 3n ; n = number of visits
For 15 visits ; n = 15
Amount paid :
Members = 21 + 3(15) = 21 + 45 = $66
Non - Member = 4(15) = 60
Difference :
$66 - 60 = 6
Members incur $6 more than non - members
