Any Brainily People out there? Please help me I’m so confused!?! 8th grade sucks
Write a linear system for the two plans.

Answer:

64

Step-by-step explanation:

6 times 4 =24

10 time 4 =40

24+40=64

Answer:

64

Do 16 + 16 + 16 + 16 which is the same as 16 times 4

Or do 4³ to get the same result.

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

answer: angle B = 102 degrees

Step-by-step explanation:

[tex]5\sqrt{96}[/tex].
I converted it into decimal form with a calculator and got approximately 48.9898

And if you round that, you will get the 49, which fits the inequality of

45<  [tex]5\sqrt{96}[/tex] < 50 since it becomes 45 < 49 < 50 which is true

Answer:

angle A is congruent to angle R

angle Q is congruent to angle D

angle B is congruent to angle S

angle C is congruent to angle P

side RQ is congruent to side AD

side AB is congruent to side SR

side BC is congruent to side SP

side PQ is congruent to side DC

Step-by-step explanation:

If you took the second shape and turned it counter clockwise (to the left side of your screen) about 90 degrees, you should see that they are the same shape.

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!

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: YOU CAN USE A BAR GRAPH

Answer: 0.720

Step-by-step explanation:

0.720 = 18/25

0.51 = 51/100

0.144 = 18/125

0.023 = 23/1000

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.

5/9 + 4/9 = 1

So your answer is D

Answer:

Step-by-step explanation:

In the question we are given two fraction that are ,

And 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 :

[tex] \longmapsto \: \pink{ \boxed{1}}[/tex]

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:

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).

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.

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.

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.

Number of Months       Monthly Payments   Total Interest Paid

to Pay Off 21

                                                $150

21                                                                               $314.68

                                              $250

12                                                                               $184.41

                                              $500

6                                                                                $95.84

Thus, the correct conclusion from the table shows C. The more he chooses to pay off each month, the less total interest he will pay.

Answer:

  147 square meters

Step-by-step explanation:

You want the area of the given irregular figure.

The figure can be divided by a couple of lines into two rectangles and a triangle as shown in the attachment.

The 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

The 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

The 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.

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.

Good Luck!
