(can i have brainliest?)

Answer:

Step-by-step explanation:

B) Small triangle:

height = 20 - 15 = 5

base = 1

height to base =  5 :1

Medium triangle :

height = 60 -30 = 30

base = 2

height to base =  30 :2  = 15 :1

Large triangle:

height = 120 - 60 = 60

base = 4

height to base =  60 : 4 = 15 : 1

c) The ratios are same. This is true because wage and working hours are in direct proportion.

E) Take any two points. (1 , 15) & (2 , 30). Find the slope.

Slope = Change in y ÷ change in x

 m = (30-15) ÷ (2 -1) = 15/1 = 15

y -y1 = m(x -x1)

y - 15 = 15(x - 1)

y - 15 = 15x - 15

y = 15x - 15 + 15

y = 15x

Answer:

x = 19

Step-by-step explanation:

x + (x + 4) + (3x - 9) = 90°

Combine like terms

5x - 5 = 90

Add 5 on both sides

5x = 95°

Divide 5 on both sides

x = 19

Answer:

V=1357.17 m^3

V=1963.50 in^3

Step-by-step explanation:

1.

first, let's go over the volume formula for a cylinder. it is V=π*r^2*h

the problem says the radius is 6, and the height is 12. we have everything to make the equation!

V=(3.14)(6)^2(12)

V=(3.14)(36)(12)

V=1357.17

2.

let's do the same thing as the first time. the radius is 5. and the height is 25.

V=πr^2h

V=(3.14)(5^2)(25)

V=(3.14)(25)(25)

V=1963.50

Answer:

Step-by-step explanation:

The quadratic equation for his flight path is y = a(x² - 32x + 156) where a is a constant if the Blue bird began at location (6,0) and hit the ground at (26,0).

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

We know the standard form of a quadratic function:

y = ax² + bx + c

Plug x = 6 and y = 0

0 = 36a + 6b + c ...(1)

Plug x = 26, and y = 0

0 = 676a + 26b + c ...(2)

From the equation (1) and equation (2) find the value of b and c

b = -32a

c = 156a

Plug this values in the standard form of a quadratic equation:

y = ax² + (-32a)x + 156a

y = a(x² - 32x + 156)

The above quadratic equation represents the flight path.

Let's take the value of a = -1

y = -1(x² - 32x + 156) (refer attached picture for the path of the graph)

Thus, the quadratic equation for his flight path is y = a(x² - 32x + 156) where a is a constant if the Blue bird began at location (6,0) and hit the ground at (26,0).

Answer:

blue increased is addition

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

It can't be A because you aren't using the distributive property. It's not B because using that logic 2+3=4+7 which is not true. It's not c because 3x+7 does not equal 3x+9. So the only logical answer is D.

Answer:

It's A.

Step-by-step explanation:

Its a because 3x+4 and 2+3x+2 are both equivalent. The 2+2 is distributive for 4 in 3x+4. For example, x=2.

3(2)+4 = 10.

2+3(2)+2=10

Answer:The cost for zachs lunch is 12$, and the cost for brins is 8$

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

I'm pretty sure it's B. Sorry if I'm wrong.

Answer:

wouldn't it be B

Step-by-step explanation:

because the formula is 2pi r  but with the 2 at the bottom the pi r  would be at the top.

Answer:

A. The label is heavier than the actual weight.

B. The actual weight is 0.0042 less than the labeled weight.

Step-by-step explanation:

I hope I'm correct but here's my explanation.

A. The label said it is 0.384 and the actual weight is 0.3798, which in terms of suggesting the label is just 0.3840 and the actual weight is 0.3798, then the labeled weight would be heavier since it has either rounded up or was guessed.

B. The actual weight is 0.3798 and the labeled weight (assuming after the last decimal number it is zero) would be 0.384. Subtract, and it would be 0.0042.

Though I'm not sure if I'm 100% correct, I do think this might be the most accurate way to solve this.

Hope this helped!

Answer:

5:2

Step-by-step explanation:

Triangle LMN's base length is 15 and triangle XYZ's base length is 6. Since they are both base lenghts, you can just use those numbers in a ratio and simply.

15:6

Divide both sides by 3 and you get 5:2!

Answer:

The distance between Points A and B is 1.

Step-by-step explanation:

Given that Point A is located at -0.75 and Point B is located at 1/4 on a number line, to determine which expression shows how to find the distance between points A and B the following calculation must be performed:

1/4 = 0.25

-0.75 + X = 0.25

X = 0.25 - (-0.75)

X = 0.25 + 0.75

X = 1

Therefore, the distance between Points A and B is 1.

tbh im sorry i dont know :(
