HOURS WORKED
Answers
Answer:
B is false.
Step-by-step explanation:
So based offf the graph, he earns about 7.50 per hour, so A is true, because 7.50(14)= 105.00 or 105, add the dollar. Meaning B has to be false.
If he works 14 hours then he will earn the amount of $105 which is true and if he works 16 hours then he will earn $120 which is true.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The given graph represents Cody's work and the amount of money he earns at his job.
According to the given graph,
We can see two points are (4, 30) and (8, 60)
The linear equation will be
⇒ y - 30 = (60-30)/(8-4)(x-4)
⇒ y - 30 = (30)/(4)(x-4)
⇒ y - 30 = 7.5(x-4)
⇒ y = 7.5x - 30 + 30
⇒ y = 7.5x
Cody's work = 14 hours then we verify the response by substituting x = 14 in the above equation,
⇒ y = 7.5(14)
⇒ y = 105
Thus, if he works 14 hours then he will earn $105
Cody's work = 16 hours then we verify the response by substituting x = 16 in the above equation,
⇒ y = 7.5(16)
⇒ y = 120
Thus, if he works 16 hours then he will earn $120.

Answers
Answer:
(8, - 5 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 4 → (1)
- x - 3y = 7 → (2)
Multiplying (2) by 3 and adding to (1) will eliminate the x- term.
- 3x - 9y = 21 → (3)
Add (1) and (3) term by term to eliminate x, that is
0 - 5y = 25
- 5y = 25 ( divide both sides by - 5 )
y = - 5
Substitute y = - 5 into either of the 2 equations and solve for x
Substituting into (1)
3x + 4(- 5) = 4
3x - 20 = 4 ( add 20 to both sides )
3x = 24 ( divide both sides by 3 )
x = 8
solution is (8, - 5 )

Liang bought a basket of apples to make pies for her friends. The basket of apples weighed ppp pounds. Before she had time to make the pies, she ate 3 pounds of apples. There are 17 pounds of apples left to make pies.
Write an equation to describe this situation.
What was the total weight of the basket of apples?
Answers
Answer:
Equation: p - 3 = 17
Weight of basket of apples = 20 pounds
Step-by-step explanation:
Given that:
Weight of basket of apples = p
Weight of apples eaten by Liang = 3 pounds
Weight of left apples = 17 pounds
According to given statement.
p - 3 = 17
Adding 3 on both sides
p - 3 + 3 = 17 + 3
p = 20 pounds
Hence,
Equation: p - 3 = 17
Weight of basket of apples = 20 pounds

Given that p varies jointly as q and r, and p = 7. when q = 2
and r= 1.5, find the following:
a. an equation relating p, q, and r
b. p when q = 4 and r= 6
c. p when p=1 and r=3
d. r when p= 5 and q = 8
Answers
Answer:
P = k*q*r
Step-by-step explanation:
P = kqr
7 = k*2*1.5
7 = 3k
k = 7/3
b. P = kqr
= 7/3*4*6
= (7*4*6)/3
= 168/3
= 56
P = 56
c. P = kqr
1 = 7/3*q*3
1 = (7*q*3)/3
1 = 21q/3
Cross product
1*3 = 21q
3 = 21q
q = 3/21
= 1/7
q = 1/7

The diameter of a baseball is approximately 3 inches. What is its volume?
Round your answer to the nearest whole number.
A. 9 in^3
B. 13 in^3
C. 113 in^3
D. 14 in^3
Answers
Answer:qe
Step-by-step explanation:
The volume of the baseball is 14 in³.
The volume of a sphere can be calculated using the formula:
V = (4/3)πr³
where V is the volume and r is the radius of the sphere.
We have,
Diameter = 3 inch
radius = diameter / 2 = 3 / 2 = 1.5 inches
Substituting the radius into the volume formula:
V = (4/3) π (1.5)³
V ≈ (4/3) x 3.14 x (1.5)³
V ≈ 14.13 in³
Thus, the volume of the baseball is 14 in³.

Multiply: (7y^3/5)(6x+5/21y)
Answers
Answer:
y²(6x+5)/15Step-by-step explanation:
We are to multiply the expression (7y^3/5)(6x+5/21y)
(7y^3/5)(6x+5/21y) = 7 * y * y * y/5 * 6x+5/21y
(7y^3/5)(6x+5/21y) = y²/5 * 6x+5/3
(7y^3/5)(6x+5/21y) = y²(6x+5)/5*3
(7y^3/5)(6x+5/21y) = y²(6x+5)/15
