Plzzzzz give me Brainliest!!!!!
Answer:
A=b×h
Hence: 12 × 8= 96 square units
C=(y-6)h solve for y
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:y=c/h +6
what expression is equivalent to h + 5 + 3 - 2h
The equivalent expression of h + 5 + 3 - 2h is -h+8.
What are the equivalent expressions?Expressions that are equivalent to the same thing, even when they have distinct appearances. When we enter the same value(s) for the variable, two algebraic expressions that are equivalent have the same value (s).
We have the expression:
h + 5 + 3 - 2h
To find the equivalent expression:
We simplify the expression,
h + 5 + 3 - 2h
= h -2h +5+ 3
= -h +8
-h+8 is the equivalent expression of h + 5 + 3 - 2h.
Therefore, -h +8 is the equivalent expression.

The perimeter of a rectangle is 160 feet. If the length of the rectangle is 28 feet more than the width, what are the dimensions of the rectangle?
Answer:
width = 26 ft
length = 54 ft
Step-by-step explanation:
perimeter = 160 ft
width = x
length = x + 28
Perimeter = 2(width) + 2(length)
[tex]2x + 2(x + 28) = 160 \\ 2x + 2x + 56 = 16 0\\ 4x = 160 - 56 \\ x = \frac{104}{4} \\ x = 26[/tex]
width = x = 26
length = x + 28 = 26 + 28 = 54

Mariah is training for the marathon. Today she ran 12 miles for 1 hour and 30 minutes . If the relationship between her distance covered and the number of minutes is proportional, write an equation that Mariah can use to represent the proportional relationship between her distance ( d ) and her time ( t).
Answer:
d= 8 t
Step-by-step explanation:
In 1 hour 30 minutes it ran for 12 miles.
So, time t =1.5 hours(Because 1 hour 30 minutes)
distance d =12
We know distance d= rate 'r' * time 't'.
So, using given information , find the rate
12= r *1.5
Divide both sides by 1.5
8=r
So, equation would be d =8 t.
Where 't' is in hours.

a recipe needs 4/5 cup(s) of sugar for every 3 cups of flour. if you plan to use 7 1/2 cups of flour, how much sugar will you need?
Answer:
2 cups of sugar
Step-by-step explanation:
Set up a proportion where x is the amount of sugar for 7.5 flour cups
[tex]\frac{3}{0.8}[/tex] = [tex]\frac{7.5}{x}[/tex]
Cross multiply and solve for x:
3x = 6

Answer:
[tex]b_2 = \frac{2A}{h} -b_1[/tex]
Step-by-step explanation:
Given
[tex]A = \frac{1}{2}h(b_1 + b_2)[/tex]
Required
Select equivalent expressions
Multiply through by 2
[tex]2*A = 2*\frac{1}{2}h(b_1 + b_2)[/tex]
[tex]2*A = h(b_1 + b_2)[/tex]
[tex]2A = h(b_1 + b_2)[/tex]
Divide through by h
[tex]\frac{2A}{h} = \frac{h(b_1 + b_2)}{h}[/tex]
[tex]\frac{2A}{h} = b_1 + b_2[/tex]
Subtract b1 from both sides
[tex]\frac{2A}{h} -b_1= -b_1 + b_1 + b_2[/tex]
[tex]\frac{2A}{h} -b_1= b_2[/tex]
[tex]b_2 = \frac{2A}{h} -b_1[/tex]

Answer:
Let P(–2, 5) and Q(–5, 9).
The component form of Vector P Q is – 3, 4
The magnitude of Vector P Q is 5
To the nearest degree, the direction angle of Vector P Q is 127º
If Vector P Q is multiplied by the scalar –10, the new vector will be in the opposite direction but longer than the original vector.

Element X decays radioactively with a half life of 13 minutes. If there are 530 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 11 grams?
Answer:
72.7 minutes
Step-by-step explanation:
From the above question, we can deduce that we are to find the time(t) of decay.
The formula used for this calculation is given as:
N(t) = No(1/2)^t/t½
N(t) = quantity of the substance remaining = 11 grams
No = initial quantity of the substance = 530 grams
t = time elapsed
t½ = half life of the substance = 13 minutes
Making t , the subject of the formula
t = t½ × In(N(t)/No)/-In2
t = 13 × In(11/530)/-In2
t = 72.675420100572minutes
Approximately 72.7 minutes

Which fraction has a a value that’s equal to 3/4?
Which statement describes the mapping?
Group of answer choices
A. The mapping does not represent y as a function of x, because two of the x-values corresponds to the same y-value.
B. The mapping represents y as a function of x, because each y-value corresponds to exactly one x-value.
C. The mapping does not represent y as a function of x, because there are more x-values than different corresponding y-values.
D. The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value.
Answer:
b. The mapping represents y as a function of x, because each y-value corresponds to exactly one x-value.
Step-by-step explanation:
Solve the system by substitution.
y = 5x
y = 9x + 8
Answer:
(-2,-10)
Step-by-step explanation:
So if y=5x and if y=9x+8 then those should be able to equal each other (substitution):
5x=9x+8
Subtract 5x from both sides:
0=4x+8
Subtract 8 from both sides:
-8=4x
Divide both sides by 4:
x=-2
If x=-2, then we can just plug it back into the first equation:
y=5(-2)
Simplify:
y=-10
Answer:
x = -2
y = -10
Step-by-step explanation:
So if y = 5x
Then you can put that in place of the y
5x = 9x + 8
Get the x's all on one side by subtracting
-4x = 8
Divide both sides by -4
x = -2
Then insert x into the first equation, so
y = 5(-2)
y = -10

∠Q ≅ ∠U∠Q ≅ ∠U'∠S ≅ ∠VStep-by-step explanation:
The following angles are equivalent:
Q = U = 45°
R = T = W = 225°
S = V = 90°
X = 135°
Reflection, any rigid transformation, or any uniform dilation will not change the measures of the angles. That is, U = U', for example.
So, the true angle statements are ...

4) Get Fit Headquarters charges $40 per month and $3 per exercise class. Fit Planet
charges $20 per month and $8 per exercise class. After how many exercise classes
will the monthly cost be the same at each gym? What will that cost be?
Answer:
After 4 exercise classes, the monthly cost will be the same at each gym
The cost will be $52
Step-by-step explanation:
Assume that the number of the exercise classes is x
∵ Get Fit Headquarters charges $40 per month and $3 per exercise class
∵ The number of the exercise classes is x
→ Add $40 to the product of x and $3 to get the monthly cost
∴ The monthly cost of Get Fit = 3x + 40
∵ Fit Planet charges $20 per month and $8 per exercise class
∵ The number of the exercise classes is x
→ Add $20 to the product of x and $8 to get the monthly cost
∴ The monthly cost of Fit Planet = 8x + 20
∵ They have the same monthly cost
→ Equate their monthly cost to find x
∴ 8x + 20 = 3x + 40
→ Subtract 3x from both sides
∵ 8x - 3x + 20 = 3x - 3x + 40
∴ 5x + 20 = 40
→ Subtract 20 from both sides
∵ 5x + 20 - 20 = 40 - 20
∴ 5x = 20
→ Divide both sides by 5
∴ x = 4
∵ x is the number of the exercise classes
∴ After 4 exercise classes the monthly cost will be the same at each gym
→ Substitute the value of x in one of the monthly cost to get it
∵ The monthly cost of the Get Fit = 3(4) + 40
∴ The monthly cost of the Get Fit = 12 +40
∴ The monthly cost of the Get Fit = 52
∴ The cost will be $52
