find the value of h that makes the equation true
Answer:
it should be 13! h+13
Step-by-step explanation:
this is because 20 is equal to 7+h, or 7+h=20.
if you solve this algebraically -
7+h=20
-7 -7
-----------
h = 13
so, h=13!

Latisha earns $5 an hour painting her neighbor's fence.
Part A: Create two variables and determine which is dependent and which is independent for this situation. (4 points)
Part B: List three ordered pairs to show the values of the two variables. (3 points)
Part C: Write an equation to represent the relationship between the two variables. (3 points)
Please I really need help!
Answer:
Part A: Variables : M = money, H = number of hours. So the number of hours(H) is independent and the money(M) is a dependent variable.
Part B: Ordered pairs : (0 Hours, 0$), ( 1 Hour, 5$), (2 Hours, 10$)
Part C: H*5 = M
Step-by-step explanation:
Part A: The money is dependent on the number of hours because per hour she paints the fence, she gets 5$. So the hour changes, and because of this, Latisha gets 5$ more.
Part B: The ordered pairs are in the form (number of hours, money).
Part C: H*5 = M. A few examples of this are 1x5=5, 2x5=10, 10x5=50.

Find the Surface Area of the prism pleese
Answer:
I'm unsure of the answer but here's how to solve it yourself :)
Step-by-step explanation:
area of a prism is obtained by taking the sum of (twice the base area) and (the lateral surface area of the prism). The surface area of a prism is given as S = (2 × Base Area) + (Base perimeter × height) where "S" is the surface area of the prism.

Answer:
1. D- All of the above
2. B- The material the acid is poured on
3. C- Mass of the ball
4. A- Temperature
Step-by-step explanation:
2. The control variable is what stays the same so the material the acid is poured on must be the same as different materials have different reactions to acids.
3. The independent variable is what's being changed and in this experiment the mass of the ball is changed each time
4. The independent variable is what's being changed and in this experiment the temperature is different in each cup.

Answer:
147 square meters
Step-by-step explanation:
You want the area of the given irregular figure.
CompositionThe figure can be divided by a couple of lines into two rectangles and a triangle as shown in the attachment.
Rectangle areaThe area of a rectangle is the product of its length and width. The upper rectangle is 9 m wide and 4 m high, so has an area ...
A = LW = (9 m)(4 m) = 36 m²
The lower rectangle is 3 m wide and 7 m high, so has an area ...
A = (7 m)(3 m) = 21 m²
Triangle areaThe triangle has a base of 18 m and a height of 10 m, so an area of ...
A = 1/2bh
A = 1/2(18 m)(10 m) = 90 m²
Total areaThe area of the entire figure is the sum of the areas of its parts. That is ...
total are = 36 m² +21 m² +90 m² = 147 m²
The area of the figure is 147 square meters.

Write the algebraic expression that matches each graph
Answer:
1. y= |x| -15
2. y = -|x| +3
Step-by-step explanation
.The V shape means absolute value (the | | ), since its upside down, the equation has to be negative. The tip of the V doesn't start at 0 like normal, it's up 3, so the equation has a +3 at the end. The x intercept at (3, 0) is just so you can check your work. If we plug in 3 for x, we do in fact get 0 for y.

Answer:
Option D. that is 1Step-by-step explanation:
In the question we are given two fraction that are ,
5/44/9And we have asked to add the fraction and reduce them to their lowest terms. So , Starting Solution :
[tex] \longmapsto \: \frac{5}{9} + \frac{4}{9} [/tex]
Step 1 : As we can see that denominator of both the fraction is same i.e. 9 . So simply adding the equation :
[tex] \longmapsto \: \frac{5 + 4}{9} [/tex]
[tex] \longmapsto \: \cancel{\frac{9}{9} }[/tex]
Step 2 : Now dividing 9 by 9 to get 1 :

The perimeter of a face of a cube is 16 mm. What is its volume?
64 mm 3
4096 mm 3
512 mm 3
128 mm 3
Answer:
The volume of a cube is s cubed (s being any edge of the cube.) You divide the perimeter by 4 to get the length of one edge. 16:4= 4. Then you cube 4.4•4•4= 64. So the answer is 64 mm cubed.

20 POINTS + BRAINLEIST
Answer:
Step-by-step explanation:
The (positive) slope of the line whose domain is (-infinity, -1) is
m = rise/run = 1/1, or m = 1. The (negative) slope of the other line segment is
m = rise/run = -1/1, or m = -1.
Let's now find the equation of the line with m = 1. Using the slope-intercept form, y = mx + b, where m = +1, we get 1 = +1(-1) + b, or b = 2. Then the equation is y = x + 2 on the domain (-infinity, -1).
Now find the equation of the line with negative slope:
y = -x + b; the y-intercept is immediately evident from the graph as b = 0.
Then the desired eequation is y = -x on the domain (-1, infinity).

A. The more he chooses to pay off each month, the higher total interest he will pay.
B. The quicker he pays off the credit card, the more interest he will pay.
C. The more he chooses to pay off each month, the less total interest he will pay.
D. The amount he chooses to pay each month will not affect the total interest he pays.
letter B is the answer
Step-by-step explanation:
she needs some credit
The correct conclusion from the table shows C. The more he chooses to pay off each month, the less total interest he will pay.
How is interest determined?The interest amount is calculated based on the outstanding balance.
When a cardholder makes more monthly payments, the interest amount reduces because of the reduction in the outstanding balance.

What is the measure of angle B?
Answer:
102°
Step-by-step explanation:
Triangle has 180 degrees
We know the degree values of two angles already.
50+28+x=180
x=180-50-28
x=102
The 3 inside angles need to equal 180 when added together
angle B = 180 - 50 -28 = 102
