Trent and Vivian go to the basketball court at the park for 45 minutes after school to practice shooting free throws. Each person shoots for an equal amount of time, while the other person rebounds the ball. How long does each person shoot free throws? Write your answer as a proper fraction or mixed number.
Answer:
22¹/₂ minutes
Step-by-step explanation:
If Trent and Vivian go to the basketball court at the park for 45 minutes after school to practice shooting free throws, the total time it takes for the both of them to shoot free throws is 45 minutes.
Let the amount of time Trent and Vivian shoot the free throws be t₁ and t₂ respectively.
Since they both throw at equal times, t₁ = t₂ = t.
Now t₁ + t₂ = 45 the total time it takes to shoot the free throws.
Since, t₁ = t₂ = t.
t₁ + t₂ = 45
substituting t into the equation, we have
t + t = 45
adding the t's, we have
2t = 45
dividing both sides by 2, we have
t = 45/2
t = 22¹/₂ minutes
So, it takes each person 22¹/₂ minutes to shoot free throws.
Answer:
22 1/2 minutes
Step-by-step explanation:
45 divided by two =22 1/2

help me please
Step-by-step explanation:
In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. so i think B and D
The given numbers 645+9√4 and 645×9√4 are rational numbers.
Option A and C are correct.
Rational number :A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero.
The given options are,
A. 645+9√4 = 645 + (9*2) = 645 + 18 = 663
Since above number can be expressed as the ratio of the integers.
So that, given number is rational number.
C. 645×9√4 = 645 * 9 * 2 = 11,610
Since above number can be expressed as the ratio of the integers.

Tavon has a gift card for 115 that loses 2.50 for each 30-day period it is not used. He has another gift card for 95 that loses 2 for each 30-day period it is not used. a. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal. b. What will the value of each card be when they have equal value?
If x is the number of 30-day periods, then the equation _____
nothing can be used to find the number of 30-day periods until the values of the gift cards will be equal
Answer:
a) Equation: 115 - 2.5x = 95 - 2x
ii) x = 40
b) The value of each gift card for which they'll be equal = 15
Step-by-step explanation:
a) Equation for the number of 30 days until the value of the gift cards are equal:
card 1: gift card for 115 that loses 2.50 for each 30-day period
115 - 2.5x - - - - (1)
card 2: gift card for 95 that loses 2 for each 30-day period
95 - 2x - - - - - - (2)
equation for the number of 30 day period (x) for which the amount on card 1 is eqaul to the amount on card 2 is given by:
115 - 2.5x = 95 - 2x
making x the subject of the formula:
115 - 95 = -2x + 2.5x
20 = 0.5x - - - - (i)
x = 20 ÷ 0.5
x = 40
b) the value on the gift card
From expression 1 above; 115 - 2.5x
where x = 40
115 - 2.5x = 115 - 2.5(40)
= 115 - 100 = 15
from expression (2); 95 - 2x
95 - 2(40) = 95 - 80 = 15
∴ The value of each gift card for which they'll be equal = 15

Anthony charges $15 an hour for tutoring and $10 an hour for babysitting. He can work no more than 14 hours a week. How many hours should Anthony spend on each job if he wants to earn at least $125 each week?
Select a system of inequalities to represent the situation. Let x represent hours of tutoring and y represent hours of babysitting.
A)
x+y≤14; 10x+15y≥125.
B)
x+y≤14; 15x+10y≥125.
C)
x+y≥14; 15x+10y≥125.
D)
x+y≤125; 15x+10y≥14.
Answer:
Step-by-step explanation:
C
The system of inequalities representing the given situation is x + y ≥ 14; 15x + 10y ≥ 125. which is the correct answer would be an option (C)
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
To determine the number of hours should he spend on each job if he wants to earn at least $125 each week.
Let the hours of tutoring would be x
And y the hours of babysitting would be y
Given that He can work no more than 14 hours a week.
So inequality as per the above situation is: x + y ≥ 14
Since he charges $15 an hour for tutoring and $10 an hour for babysitting.
If he wants to earn at least $125 each week.
So inequality as per the above situation is: 15x + 10y ≥ 125
Therefore, the correct answer would be option (C).

Which statement is true about parallel lines?
A. They intersect and are coplanar.
B. They intersect, but are not coplanar.
C. They do not intersect, but are coplanar.
D. They do not intersect and are not coplanar.
Answer:
C( They do not intersect, but are coplanar
Step-by-step explanation:
Parallel lines are coplanar (they lie in the same plane) and never intersect.
The statement that is true about parallel lines is that they do not intersect, but are coplanar: Option C is correct.
Lines are 2-dimensional figures that are used to connect two on more points in a xy-plane.
For two lines to be parallel, this means that the lines;
cannot meet each other i.e. they can not intersectThey can lie on the same plane i.e they can be coplanarHence we can conclude that the statement that is true about parallel lines is that they do not intersect, but are coplanar.

If the area of a square is 33 square inches, which is greater: the length of a side of the of a side of the square to the nearest tenth of an inch or the square root of 40?
Answer:
square root of 40 is greater than side of the square
Step-by-step explanation:
First we find square root of 40
[tex]\sqrt{40} = 6.325[/tex]
Now
given
area of a square is 33 square inches
we know area of square is side square
area of square = [tex]side^2[/tex]
[tex]side^2 = 33\\\sqrt{side^2} = \sqrt{33}\\side = 5.745[/tex]
Thus, we see length side of square is 5.7 inches
and square root of 40 is 6.325
since
6.325 > 5.7
hence square root of 40 is greater

40

Of(x) - 2x - 6
O f(x) = 2x + 9
Answer:
[tex]f(x)= -2x + 9[/tex]
Step-by-step explanation:
The table is not properly formatted:
We have:
x ------- y
0 ------- 9
1 ------- 7
2 ------- 5
3 ------- 3
4 ------- 1
Required
Determine the linear equation
Since, it is a linear equation.
We need to first determine the slope.
Take any to corresponding values of x and y
[tex](x_1,y_1) = (0,9)[/tex]
[tex](x_2,y_2) = (4,1)[/tex]
Slope is then calculated as thus:
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]
[tex]m = \frac{9 - 1}{0 - 4}[/tex]
[tex]m = \frac{8}{- 4}[/tex]
[tex]m = -2[/tex]
The linear equation is then calculated as thus:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 9 = -2(x - 0)[/tex]
[tex]y - 9 = -2x[/tex]
Add 9 to both sides
[tex]y - 9 + 9= -2x + 9[/tex]
[tex]y = -2x + 9[/tex]
[tex]f(x)= -2x + 9[/tex]
