Answer:

45

Step-by-step explanation:

what is the area of a triangle (At) ?

At = base line × height / 2 = 12×12/2 = 72 in²

what is the area of a rectangle (Ar) ?

Ar = length × width (or height - however you see or name the second dimension)

so, the area of that inner rectangle is 3×9 = 27 in²

now the main question is about the area of the triangle without the inner rectangle.

this is simply At - Ar = 72 - 27 = 45 in²

that's it. you only need to translate the English sentence into the corresponding mathematical expressions and use the mathematical operators just as the sentence states.

we did exactly and nothing else than what the original problem statement said.

Answer:

B. 45

Step-by-step explanation:

do 12×12 which is 144 then Davide it by 2 because it's a triangle then do 9×3 which is 27 then subtract that from 72 and you get 45.

6. Which of the following is true about the
Gnom [1K]
C.
Y=mx + b is the formula (M being slope, and B being the y intercept) always start by going up or down by what the y-intercept number is, if it’s -9 you go down the y axis 9 numbers from the origin (0,0) and slope (m) is always better put in a fraction-5x is better put in -5/1x
Think of the top number of the fraction as ‘up/down’ and the bottom number as ‘over’ if the top number is negative you will go down from the y-intercept number that many times, the bottom number is how many spots you go over from that number , it is always to the right.

scoray [572]

Answer:

<h2>x = 9/17</h2>

Step-by-step explanation:

3(7x-1)=4x+6  distribute

21x - 3 = 4x + 6  combine similar terms

21x - 4x = 6 + 3  simplify

17x = 9

x = 9/17

MARKING BRAINLIST! PLEASE HELP!
Leviafan [203]

Answer:

\boxed {\boxed {\sf C. \ 4 \ inches}}

Step-by-step explanation:

Circumference is the perimeter of a circle. It can be found using the formula:

c= \pi d

However, we are given the radius.

  • The radius measures from the center to the edge of the circle.
  • The diameter measures from edge to edge through the center.
  • So, the diameter is twice the radius, or d=2r

The formula can be rewritten as:

c= \pi 2 r

We know the circumference is 25.12 inches.

25.12 \ in = \pi 2r

Let's round pi to 3.14

25.12 \ in = (3.14) 2r

We want to solve for the radius, so we must isolate it.

Divide both sides by 3.14 because the inverse of multiplication is division.

25.12 \ in / 3.14= (3.14 ) 2r  / 3.14

8 \ in = 2r

Divide both sides by 2.

8 \ in / 2 = 2r/2

4 \ in = r

The radius of the disc is <u>4 inches.</u>

Write the slope-intercept form of an equation that passes through the given points.<br> (4,1),(8,2)
Talja [164]

Answer:

y = 1/4x or y = 0.25x

Step-by-step explanation:

In this question, we are trying to write an equation with the given points.

To solve this question, we would use the slope formula: y2-y1/x2-x1

Find the slope by plugging in variables:

2-1/8-4

1/4 = m

The slope would be 1/4

Find the y intercept:

To find the y-intercept, you would need to use the slope you've found and one point, and plug it into the slope-intercept equation:

1 = 1/4(4) + b

Solve:

1 = 1/4(4) + b

1 = 1 + b

Subtract 1 from both sides

0 = b

This means that the y-intercept is 0.

Our equation will be: y = 1/4x
