Answer:

H

Step-by-step explanation:

Sum of angles in a triangle is 180 degrees

That means

180= 25 + 45+ unknown angle

180= 70 + unknown angle

180 - 70 = unknown angle

110 = unknown angle

9514 1404 393

Answer:

  28 cm

Step-by-step explanation:

For the similar figures, a proportion can relate the side lengths.

  x/(7 cm) = 11.2/2.8

  x = (7cm)(11.2/2.8) = 28 cm

The value of x is 28 cm.

Answer:

Answer: -2

Step-by-step explanation:

Subtract 13 on both sides

-7x = 14

Divide by -7 on both sides

Answer:

Average rate of change = [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

We have to calculate the average rate of change of the graph at x = 2 to x = 5.

From the graph attached,

At x = 2,

f(2) = 3

At x = 5,

f(5) = 7

Since, average rate of change of the function between x = a and x = b is defined by,

Average rate of change = [tex]\frac{f(b) - f(a)}{b - a}[/tex]

Therefore, average rate of change of the function represented by the graph will be = [tex]\frac{7-3}{5-2}[/tex]

           = [tex]\frac{4}{3}[/tex]

Answer: there are 7 in the water

Step-by-step explanation:

The distance from the origin to the point (-27,36) is 45

We are going to make use of  Pythagorean Theorem to determine the length of the hypotenuse of the right triangle:

Hence;

  (0,0) to (-27,0)

  (-27,0) to (-27,36)

Using this formula

c2 = a^2 + b^2

Let plug in the formula

c2 = (-27)^2 + (36)^2

c2=-729+1296

c2 = √2025

 c = 45

Inconclusion The distance from the origin to the point (-27,36) is 45.

Step-by-step explanation:

Answer:

x ≈ 18.7

Step-by-step explanation:

This is a big equation, so let's break it down a bit.

[tex]\frac{3}{2} \sqrt[4]{(2(x-6) ^3 )} +4=16[/tex]

Let's start by isolating the radical which is x.

So subtract 4 from both sides :

[tex]\frac{3}{2} \sqrt[4]{(2(x-6) ^3)}[/tex][tex]=12[/tex]

Now multiply both sides by 2 to get rid of the fraction :

[tex]3\sqrt[4]{(2(x-6)^3)} = 24[/tex]

Now divide both sides by 3 to get rid of the number out of the poly root :

[tex]\sqrt[4]{2(x-6) ^3}[/tex][tex]=8[/tex]

Now take both sides of the equation to the power of 4 :

[tex]2x^3 - 36x^2+216x-432=4096[/tex]

And lastly, solve :

[tex]x = 18.69920[/tex] which is rounded up to [tex]x[/tex] ≈ [tex]18.7[/tex]

⇒ x > 8

Answer:

b=8

Step-by-step explanation:

15 +b=23

get b by itself by subtracting 15 on both sides

b=8

the answer is

 =  8

you need to Subtract  15  from both sides of the equation

+ 15 = 23 + 15 − 15 = 23 − 15

simplify

and then you get your answer

9000 divided by 1000=9

Answer: 9 liters in total = 9,000 milliliters

Step-by-step explanation: 25*8=200

225*40=9,000

9,000/1,000=9

9/5 = 1.8

Answer:

y=70x+20

Step-by-step explanation:

Okay so the slope is determined by having two points on the line in this case one of them is (0,20) and (2,160), you're going 140 up and 2 over so the slope would be [tex]\frac{140}{2}[/tex] which equals 70 so thats how you get m, to get b you simply put the y interecept which is at 20.

Plugs those numbers together you get y=70x+20 which is intercept form.
