How do you find the area of a triangle?
Example on picture

Answer:

(1200-650)/25=22

Step-by-step explanation:

1200-650=550

25x_=550 or 550/25=_

They need to sell 550 before he restocks

(1200-650)/25=22

I think lol

I tried hope that helps :)

Answer:

B. 4 ft

Step-by-step explanation:

First, find the width of the wall.

The length, width, and diagonal form a right triangle, where the diagonal is the hypotenuse and the length and width are the 2 legs.

Use the pythagorean theorem and solve for a, the width of the wall.

a² + b² = c²

a² + 16² = 20²

a² + 256 = 400

a² = 144

a = 12

So, the width of the wall is 12 feet.

Solve for the width of the mural. Again, the diagonal, length, and width form a right triangle.

Use the pythagorean theorem again and solve for a, the width of the mural:

a² + b² = c²

a² + 6² = 10²

a² + 36 = 100

a² = 64

a = 8

So, the width of the mural is 8 feet.

Now, find the difference between the widths of the wall and mural:

12 - 8

= 4

So, the difference between the two widths is B. 4 ft

Step-by-step explanation:

Answer:

A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled. Because of this, it is also called a direct variation. The equations of such relationships are always in the form y = mx , and when graphed produce a line that passes through the origin. In this equation, m is the slope of the line, and it is also called the unit rate, the rate of change, or the constant of proportionality of the function.

Answer:

mario paid 15,000$ for his car

Answer: $15,000

Step-by-step explanation:

This is basic proportions.

We are given that 9000=60%

Therfore 100%=X.

Using the formula of proportions, we can calculate (9000*100)/60

This gives up 15000

Therfore he paid $15,000 for his car, which is 100% of the price.

Answer:

The best measure for center is median and its value is 60 .

Step-by-step explanation:

MEDIAN MEASURES MIDDLE ; 60 is in the middle .

Answer:

D. 600 [tex]cm^{2}[/tex]

Step-by-step explanation:

Volume of a cube = [tex]s^{3}[/tex] = 1000, s = [tex]\sqrt[3]{1000} =10[/tex]

So, the side length is 10 cm

Surface area of a cube is 6[tex]s^{2}[/tex] where s is the side length

so [tex]s^{2}[/tex] = [tex]10cm^{2} = 100 cm^2[/tex]

6*100[tex]cm^{2}[/tex] = 600 [tex]cm^{2}[/tex]

So the answer is D. 600 cm (it should have a little superscript 2 next to it)

Answer:

A. X

Step-by-step explanation:

It's a right-angled triangle, so the hypotenuse is always longer than either of the other legs.

True,

2.2 is equal to 2.2 Imagine it like this.

22 < 225 correct right? Well look at this 22<22 is wrong it should be equal, so we added on a five to make it more greater!

Answer:

false

Step-by-step explanation:

≤ means greater than or equal to. 2.25 is greater than 2.2, there isn't a possibility that 2.2 is greater than 2.5 even if it was estimated 2.4 would be the greatest number, hence the use of ≤  is invalid.

Answer:

Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Number of lemons used is denoted by 'y'.

Number of glasses of lemonade is denoted by 'x'.

As we can observe that ,

[tex]\frac{6}{24} = \frac{8}{32} = \frac{7}{28} = \frac{2}{8} = \frac{4}{16} = \frac{1}{4} \\[/tex]

so we can write i as

[tex]\frac{x}{y} = \frac{1}{4}[/tex]

By cross multiplication

y=4x

So, if write it in the form y=kx,

It will be y=4x.

Answer:

Look at the image.

Step-by-step explanation:

y = - 3 - 2x

y = - 3 - 2( - 5)

y = - 3 + 10

y = 7

y = - 3 - 2( - 2)

y = - 3 + 4

y = 1

y = - 3 - 2( - 1)

y = - 3 + 2

y = - 1

y = - 3 - 2(2)

y = - 3 - 4

y = - 7

Answer:

There are 6 fiction books in the bin. The probability of randomly selecting a fiction book from the bin is 0.6 or 3/5.

Step-by-step explanation:

The third bullet point says that the probability of selecting a poetry book is 1/5, and the second point says that the probability of selecting a fiction book is three times as likely than the poetry books.  So that would mean we must multiply 1/5 by 3. So do that you could turn it into a decimal first. 1/5 as a decimal is 0.2. Next, we multiply it. So 0.2 times 3 equals 0.6. Therefore the answer is 0.6. And to convert that back to a fraction, it would be 3/5.

Answer:

the tree is 30 ft tall

Step-by-step explanation:

27/x = 4.5/5

cross multiply

(4.5)(x) = (27)(5)

4.5x = 135

divide the entire equation by 4.5 to isolate x

135/4.5 = 30

x = 30

Answer:

30ft

Step-by-step explanation:

Proportion/ratio question

Tree : Your friend

27ft  :   4.5ft

?      :   5ft

Formula given divided by the original or missing value equivalent

g/o = 5/4.5 = 1.11111 multiplier

Then use multiplier for the tree given value.

27 x 1.111111 = 29.999997

= 30ft
