Answer for question 1: 52
Answer for Question 2: 68
Answer for question 3: 40
Answer for Question 4: 25
Step-by-step explanation:
1: [tex](4 + 3)^2[/tex] = [tex]7^2[/tex] = 49 (12 ÷ 4) = 3
3 + 49 = 52
2: [tex](12 * 9- 7^2) + 9[/tex] = 12 * 9 = 108 - 49 = 59 + 9 = 68
3: 28 ÷ 7 = 4 + [tex]6^2[/tex] = 40
4: [tex](2 * 7 + 4^2) - 5[/tex] = 2 * 7 = 14 + 16 = 30 - 5 = 25

Sam’s discount shoes is have a 40 percent off sale. A — use the percent ruler at right to find how much Lorna will save on her purchase of 80 dollar professional basketball shoes. B What will she pay for the shoes?
Answers
Answer:
A, 32
B, 48
Step-by-step explanation:
Since the discount is 40% off, she will save 40% of the 80 dollar shoes, which is 40% of 80 dollars. 40 * 80 = 3200, and 3200/100 = 32 dollars worth of savings. She will pay a total of 80 dollars minus the 32 dollar discount to get a total of 48 dollar payment.
Answer:
40% off that means her shoes will be 60% of the value so 80* 0.6 or 60% = $48 she will pay and 32 she will save

how much water should be added to 5 gallons of 50% acid solution to get a 20% solution?
Answers
Answer:
7.5 gallons
Step-by-step explanation:
2.5/5+x=0.2
This question is based on the concept of solving an equation. Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.
Given:
5 gallons of 50% acid solution to get a 20% solution.
According to question,
Let it be x gallons of water should be added to 5 gallons of 50% acid solution to get a 20% solution.
Now, forming the equation, we get,
0.50 ( 5 ) = 0.20 ( x + 5 )
Simplifying the equation.
We get,
2.5 = 0.2x + 1
1.5 = 0.2 x
x = 7.5
Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.

What is the range of possible sizes for side x? _ < x < _
Answers
Answer:
0.5 < x < 16.5
Step-by-step explanation:
The third side of the triangle must be longer than the difference of the other two sides:
x > (8.5 -8.0)
x > 0.5
And it must be shorter than their sum:
x < (8.5 +8.0)
x < 16.5
The third side must be in the range ...
0.5 < x < 16.5
_____
These limits are a direct consequence of the triangle inequality, which requires the sum of the two shortest sides exceed the length of the longest side.

Relative to ground level, what is the elevation of the hole after placing the shrub in the hole? Enter your answer as a mixed number in simplest form by filling in the boxes.
Answers
Answer:
15/6
Step-by-step explanation:
(20/9) ft of the hole is elevated after the shrub was placed.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problemGiven is that Malik digs a hole at a rate of 2/3 feet every 15 minutes. After digging for 60 minutes, Malik places a shrub in the hole that fills exactly 5/6 feet of the hole.
In 15 minutes, the depth of hole digged is (2/3) feet.
In 1 minute, the depth of hole digged is {(2/3)/15} feet.
In 60 minutes, the depth of hole digged will be {(2/3)/15} x 60 = 8/3 ft.
The hole filled after placing the shrub will be -
(5/6) x (8/3)
5/6 x 8/3
5/3 x 4/3
20/9
Therefore, the (20/9) ft of the hole is elevated after the shrub was placed.

(2, -4) and (0,4);
x, y x, y
A. y = -4x +4; substitute the pairs
(2,-4)
-4 = -4(2) + 4 = -4; -4 = -4
(0,4)
4 = -4(0) + 4 = 4; 4 = 4
B. y = -4x - 4
(2, -4)
-4 = -4(2) - 4 = -12; -12 ≠ -4
(0,4)
4 = -4(0) - 4 = -4; -4 ≠ 4
C. y = 4x - 4
(2, -4)
-4 = 4(2) - 4 = 4; 4 ≠ -4
(0,4)
4 = 4(0) - 4 = -4; -4 ≠ 4
D. y = 4x + 4
(2, -4)
-4 = 4(2) + 4 = 12; 12 ≠ -4
(0,4)
4 = 4(0) + 4 = 4; 4 = 4
Answer A works out for both ordered pairs.
