Answer:

I remember these form when I was like 10 but ok.

Step-by-step explanation:

pretty sure you multiply the base times the height. But first you have to take out all triangwkes which leaves you with two of them.

so 8x4 for the top one and then 14x4.5 for the bottom one.

then for the triangles the one on the left is 5.6x4

the right one is 4.5x14

then divide both triangles answers into two. That should be the triangle areas. Then add the two triangles pieces together.

once don’t add the squares areas with the triangles and that’s THE AREAAAA

The distance traveled at a constant speed is directly proportional to
the time spent traveling. If Lynnell traveled 70 miles in 3.5 hours, how
many miles will Lynnell travel in 4 hours at the same constant speed?

Answers

Answer:

80 mi.

Step-by-step explanation:

There are a couple ways to solve this problem.  I will show you one.  First, let's find the rate of travel.

D = RT

70 = 3.5R

R = 70/3.5 = 20

Using that speed, we now get

D = 20(4) = 80 mi.

22 foot ladder is placed against a vertical wall of building with the bottom of the ladder standing on level ground 9 feet from the base of the building how high up the wall does the ladder reach

Answers

Answer:

20.1 feet

Step-by-step explanation:

We solve the above question using the Pythagoras Theorem

The Pythagoras Theorem =

Opposite² + Adjacent ² = Hypotenuse²

From the above question,

Opposite side = Height of the wall = x

Adjacent side = Distance from the base of the building = 9 feet

Hypotenuse = Length of the ladder = 22 feet

Hence:

x² + 9² = 22²

x² = 22² - 9²

x = √22² - 9²

x = √403

x = 20.0748599 feet

Approximately = 20.1 feet

Therefore, the height of the wall = 20.1 feet

Step-by-step explanation:

To get the circumference you have to multiply the diameter with pi.The radius is 12 and the diameter is the radius times 2 making the diameter 24. multiple 24 by pi and you'll get the circumference which is 75.39 which will be 75.4 when rounded

what does this equal y=8x+1
y=6x+3

Answers

Answer:

(1,9)

Step-by-step explanation:

Step 1: Understand what the question is asking you

Assuming the question is asking you to solve for the point of interesection of the linear system

Step 2: Solve

Equate the 2 linear equations to each other and solve for'x'

8x + 1 = 6x + 3

8x - 6x = 3 - 1

2x = 2

[tex]\frac{2x}{2} =\frac{2}{2}[/tex]

x = 1

Sub x = 1 into any of the 2 equation for y

y=8(1)+1

y=8 + 1

y=9

Step 3: Therefore Statement

Therefore the answer to the linear system is (1,9)

The point of intersection for the two equations is (x=1, y=9).

To find the point where the two equations intersect, we can set them equal to each other since they both represent "y." So, we have:

8x + 1 = 6x + 3

Now, let's solve for "x":

8x - 6x = 3 - 1

2x = 2

x = 2/2

x = 1

Now that we have the value of "x," we can find the corresponding value of "y" by substituting "x = 1" into either equation. Let's use the second equation:

y = 6x + 3

y = 6(1) + 3

y = 6 + 3

y = 9

So, the point of intersection for the two equations is (x=1, y=9).
