answer plz will give brainliest to the best and correct answer :)

itz only 1 question

Answer:

Area = 1/2 bh

Area = 18

Base = 9

height = ?

18 = 1/2 x 9 x h

cross multiply

18 x 2 = 1 x 9 x h

36 = 9h

divide both sides by 9

h = 4

(a) The formula for area of a triangle is expressed in terms of h as [tex]h = \frac{2A}{b}[/tex]

(b) The height, h of the triangle is calculated as 4 in

Given:

area of a triangle, [tex]A= \frac{1}{2} bh[/tex]

To find:

(a) The formula, (area of a triangle) is expressed in terms of h as;

[tex]A = \frac{1}{2} bh\\\\multiply \ both \ sides \ of \ the \ equation \ by\ 2\\\\bh = 2A\\\\divide \ through \ by \ b\\\\\frac{bh}{b} = \frac{2A}{b} \\\\h = \frac{2A}{b}[/tex]

(b) The height, h of the triangle is calculated as

[tex]h = \frac{2A}{b}\\\\Recall , A = 18 \ in^2 , \ b = 9\ in\\\\h = \frac{2\times 18}{9}\\\\h = 4 \ in[/tex]

Answer:

D. 6 1/12

Step-by-step explanation:

First add the like fractions.

3 2/3 + 2/3 = 3 4/3 (Don't worry about simplifying yet)

Now find the least common multiple for 3 4/3 and 1 3/4 so we can add them.

3: 3, 6,  9, 12

4: 4, 8, 12

In this case 12 is the least common multiple.

3/4 x 3/3 = 9/12    9/12

4/3 x 4/4 = 16/12

Add those two fractions then add the whole numbers and put it in front.

4 25/12

Answer: the correct anwser is D square root of 37

Step-by-step explanation:

Sum of two angles that are complementary = 90°

m∠1 + m∠2 = 90°

Given :

m∠1 = 12°

Then :-

[tex]12° + ∠2 = 90°[/tex]

[tex]∠2 = 90 - 12[/tex]

[tex]∠2 = 78°[/tex]

Answer:

Slope Intercept Form: y = [tex]\frac{1}{4}[/tex] x + 1

Point Slope Form: y - 2 = [tex]\frac{1}{4}[/tex] × (x - 4)

Standard Form: 1x - 4y = -4

Step-by-step explanation:

Answer:

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

Step-by-step explanation:

A linear equation needs two pieces of information: the slope of the line, and its y-intercept. Since we are already given the slope we can plug that into the standard equation format:

y=mx+c, where m=slope and c=y-intercept

y=1/4x+c

Now we just need to find the y-intercept.

To find it we are given a point: (4,2), which we can use to trace back to the y-intercept using the slope. The slope of the line of 1/4. This means that the point before it is located 4 units to the left on the x intercept, and 1 unit lower on the y-intercept. Conveniently, this gives us our y-intercept, as the x values 4-4=0. The y value is 1 (2-1) so our y-intercept is 1!

So now we have our equation:

y=1/4x+1

Answer: 325

Step-by-step explanation:

I wrote down the steps but thats the answer it took me a while to complete that was some difficult math lol.

For percentages, we write the number before the % sign as a decimal out of 1. So our percentage would actually be 0.38

To find what percent of Robinson students are 7th graders, we simply multiply 0.38 by 1200 which gives us 456

The answer is 456

Kyle incorrectly says that the product of - ( - 6 ) # ( - 1 ) is 6 . 11. After a recycling awareness program, the number of tons of recyclable material taken to the landfill is reduced by 13 7/10 tons per month. Represent the total change in the tons of recyclable material taken to the landfill after 7 months resulting from the awareness program a. What is the correct product? 10 month. Represent the total change in the b. What was Kyle's likely error?

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Kyle incorrectly says that the product of - ( - 6 ) ( - 1 ) is 6

-(-6)(-1) = 6 [incorrect]

Correction:

-(-6) (-1) :

- (-6) = 6

6 (-1) = - 6

Given that reduction in materials = 13 7/10 tons per month

Monthly reduction = 13 7/10 = 137/10 tons

After 7 months : (7 * 137/10) = 959/10 tons = 95.9 tons

Change in amount of material taken to the land fill:

Initial amount - amount after 7 months

If initial amount = x

Change in amonnt = (x - 95.9) tons

Answer:

x=-4

Step-by-step explanation:

First, you would simplify the like terms on both sides of the equation to get   42 + 12x = -8.5x - 40

Second, you would want to add and subtract terms to get the X's on one side, and the whole numbers on the other.

12x + 8.5x = -40-42

Third, simply the terms.

20.5x=-82

Fourth, divide both sides by 20.5 to get the x on its own, and then you will have your answer of x=4.

Step-by-step explanation:

supplementary= 180 degrees.

Step-by-step Explanation: If two parallel lines are cut by a transversal, then same-side interior angles are supplementary or the sum of their measures is 180 degrees.

Notice that <3 and <5 are same-side interior angles because they lie on

the same side of the transversal and on the interior of lines l and m.

Notice that same-side interior angles make a C shape.
