C) !!!
In ratios, 'things go with the same things', so recliners have to be both in the numerator or denominator. The 8 is misleading. That's the total, and the problem is all about recliners and couches only
Correct options are -10 and 10
-7 + (-10² - 19)³/⁴ = 20
-7 + (100 - 19)^3/4 = 20
-7 + (81)^3/4 = 20
-7 + 27 = 20
20 = 20
RHS = LHS
-7 + (10² - 19)^3/4 = 20
-7 + (100 - 19)^3/4 = 20
-7 + (81)^3/4 = 20
-7 + 27 = 20
20 = 20
RHS = LHS
Rest options are incorrect

Answer:
1. C) 3
2. D) -1
3. D) 7^2 - 8*2 - 16
4. B) 75
5. B) 6^2 + (2 - 8)*sqrt(81)
Step-by-step explanation:
1. (10 - (6-4)^2)/2
= (10 - 2^2)/2
= (10 - 4)/2
= 6/2
= 3
2. PEMDAS states that Multiplication is before Subtraction
8 - (5^2-7)/2
= 8 - (25-7)/2
= 8 - 18/2
= 8 - 9
= -1
3. D) 7^2 - (8*2) - 16
= 49 - 16 - 16
= 49 - 32
= 17
4. 3(2 + 3)^2
= 3(5)^2
= 3(25)
= 75
5. 6^2 + (2 - 8)*sqrt(81)
= 36 + (-6*9)
= 36 - 54
= -18
Answer:
115.625 cm³
Step-by-step explanation:
The ratio of the volumes is in proportion with the cube of the proportion of the lengths.
V1/925 = (10/20)³
V1/925 = (1/2)³
V1/925 = 1/8
V1 = 925 ÷ 8
V1 = 115.625 cm³
The value of m will be (mV₂ + Mv₂)/V₁ so Brenna's equation is absolutely correct.
<h3>What is the equation?</h3>
A formula known as an equation uses the same sign to denote the equality of two expressions.
An equation can be defined in numerous ways. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.
Given,
mv₁ = (m + M)v₂
By multiplication on the right-hand side
mv₁ = mv₂ + Mv₂
Divide v₁ on both side
mv₁/v₁ = ( mv₂ + Mv₂)/v₁
m = (mV₂ + Mv₂)/V₁
Hence Brenna's solution is correct for the equation.
