Coach De Leon purchases sports equipment. Basketballs cost $20.00 each, and soccer balls cost $18.00 each. He had a budget of $150.00. Part A: Use the drop downs to create an inequality that represent the situation. Let s represent the number of soccer balls and let b represent the number of basketballs. 18s+20b > 150 Part B: Given the coach's budget, which of the following is a viable option for the equipment he can purchase? 4 basketballs and 6 soccer balls 5 basketballs and 2 soccer balls 2 basketballs and 7 soccer balls 6 basketballs and 5 soccer balls
Answer:
5 basketballs and 2 soccer balls
Step-by-step explanation:
5 times 20= 100
2 times 18= 36
equals 136
4 basketballs and 6 soccer balls- wrong-185
2 basketballs and 7 soccer balls-wrong-166
6 basketballs and 5 soccer balls- wrong- over 200
Answer:
The Inequality Equation is
20b + 18s <_ 150
5 Basketballs and 2 Soccer Balls

Jack works after school. each day he earns a set amount, plus an hourly wage. the following table represents a linear function f jack can use to determine to his pay.
hours: 1, 2, 3 | Pay: 18, 28, 38
SLOPE is 10.
Using the slope, find the y-intercept and write the function.
Answer:
The y intercept is (0, 8). The equation of the function is f(x) = 10x + 8
Step-by-step explanation:
Given that after 1 hour of work, Jack will make 18 dollars and the slope is 10, subtract 10 dollars from 18 dollars to find his set amount, or y-intercept.
18 - 10 = 8 dollars.
Now that we have the m and b values, we can create our equation.
The equation in standard form is f(x) = mx +b, where m = the slope and b = the y-intercept. Plug our values in and the equation will be f(x) = 10x + 8. You can test if this is correct by plugging in x values from the table and seeing if your calculated value correctly corresponds to the given y value in the table.

Angelina paid $6.60 for a dozen cupcakes for a birthday party. What is the unit cost for each cupcake? *
Answer:$.55
Step-by-step explanation:
An important thing to know is that a dozen is equal to 12.
12x= 6.60
/12 /12
x=.55
Answer:
0.55$
Step-by-step explanation:
Divide $6.60 by the 12 cupcakes
6.6 divided by 12 is 0.55
So each cupcake costs $0.55

Ben wrestles in the 132 to 138-pound weight class. If he currently weighs 133 pounds, how much weight can he gain if he wishes to stay in the same class?
Answer:
X is less than or equal to 5
Step-by-step explanation:
I cant do the less than or equal to sign so I wrote it in words. Hope this helps :)
Answer:
5 pounds
Step-by-step explanation:
Let x represent Ben's weight gain.
[tex]138 \geq 133 + x\\[/tex]
Subtract 133 from both sides
[tex]5 \geq x[/tex]
Therefore, Ben can't gain more than 5 points if he wishes to stay in the same weight class.

Hurryyy !!! Lincoln Glass pays it workers overtime if they work on weekends or
holidays. Overtime is 1/2 times the usual hourly pay. If Tim was
earning $8.25 an hour, how much would he get for 1 hour of
overtime? For 8 hours of overtime?
Step-by-step explanation:
since overtime is 1/2 the usual pay which is 8.25 or 8 1/4 then its 8 1/4 (divided) by 1/2 which is equal to 4.125 or 4 1/8 so: in 1 hour the workers get paid 4 1/8 dollars and in 8 hours its 8 x 4 1/8 which is equal to 33
really hope this helps :) good luck
#Answer:
1 hour = $4.13 (rounded) . 1 hour = $4.125 (not rounded)
8 hours = $33.04 (rounded) 8 hours = $33 (not rounded)

Evaluate when x = 2, y = 7 and z = 6: 4(x + y) —z send help?
Answer:
30
Step-by-step explanation:
x = 2, y = 7 and z = 6

AB←→ intersects PQ←→ at point M;
Point C is on AB←→ ;
Point R is on PQ←→ ;
△CMR is a right triangle.
Which statement describes the relationship between AB←→ and PQ←→ ?
A.
AB←→ and PQ←→ are skew
B.
AB←→ and PQ←→ are collinear
C.
AB←→⊥PQ←→
D.
AB←→∥PQ←→
Answer:
(C). AB←→⊥PQ←→
Step-by-step explanation:
This is the only suitable answer to produce a triangle △CMR which is a right triangle.
When we will draw Line AB And PQ which they are intersecting And to produce a right triangle by taking two random points ( C on AB and P on PQ).
Then AB and PQ must be Perpendicular to each other, only then a triangle CMR will be right angled at M.
Consider the enlargement of a triangle that has a scale factor of 7.5. A small triangle has a base of 5 centimeters and height of 2 centimeters. A larger triangle has a base of b and height of a. Area Original = 1 2 (5)(2) = 5 cm2 What is the area of the enlarged triangle? cm2
Answer:
b=37.5cm
h=15cm
A=281.25
Step-by-step explanation:
The scale factor will represent how many times bigger the base and the height of the triangle are com that of the smaller triangle. So in order to find these transformations, we need to multiply the scale factor of 7.5 by both the base and the height.
b=7.5(5cm)=37.5cm
h=7.5(2cm)=15cm
so now we can find the area of the enlarged triangle by using the formula:
[tex]A_{triangle}=\frac{bh}{2}[/tex]
[tex]A=\frac{(37.5cm)(15cm)}{2}[/tex]
[tex]A=281.25 cm^{2}[/tex]
Answer:
281.25

what is the slope of the line below
Answer:
m=1/2
Step-by-step explanation:
When finding the slope of a line on a graph, I like to count the steps up/down and to the side between two of the line's points. For this line, we can see that it has points at (2,-1) and (4,0). To get from (2,-1) to (4,0), you need to count
"up 1, over 2"
1/2
Therefore, the slope is 1/2.

What is the determinant of A = [ -2 2 b 0 3 a 0 0 -5 ]
Answer:
30
Step-by-step explanation:
To find the determinant of a 3x3 matrix, you can use this method. (See picture.)
Start with the first number in the top row, and block off the row and column. A 2x2 matrix will be left. Find the determinant of this 2x2 matrix, and multiply it by the number in the top row.
Repeat for the other two numbers in the top row. Add the first result, subtract the second, and add the third.
det A = -2 [(3)(-5) − (a)(0)] − 2 [(0)(-5) − (a)(0)] + b [(0)(0) − (3)(0)]
det A = -2 (3)(-5) − 0 + 0
det A = 30
