Answer 1

Answer:

y^8 goes to the last one

y^6 goes to the third one

y^5 goes to the second one

then the last one go to the first one

Answer 2

Answer:

(y)^-2 = 1/y^2, (y^3)^2 = y^6, y^8 -:- y^3 = y^5, and y^4 x y^4 = y^8

Step-by-step explanation:

When you divide y^8 -:- y^3, you subtract ^8-^3 = ^5, so its y^8 -:- y^3 = y^5

When you multiply y^4 x y^4, you add ^4 + ^4 = ^8, so it is y^4 x y^4 = y^8

When you multiply (y^3)^2, you multiply ^3 x ^2 = ^6, so its (y^3)^2 = y^6

And when you have a negative exponent,(^-2) you have to make it positive, so it would be y^-2 = 1/y^2

1a) To find the total area, you must find the area of the triangular part that is missing, then subtract this from the area of the rectangle. For the triangle’s area, you need to know the width (2m) and length (2m). For the rectangle’s area you need to know the width (3m) and length (4m).
1b) the total area is 10m^2 (10 meters squared). This is found by subtracting the triangle (.5x2x2=2) from the rectangle (3x4=12).

What are the similar triangles?

Similar triangles have the same corresponding angle measures and proportional side lengths.

Given that, two triangles are similar, Δ MNO ~ Δ PQR,

According to definition of similar triangles,

PR/MO = QP/NM

x/4 = 2/5

x = 8/5

x = [tex]1\frac{3}{5}[/tex]

Hence, the value of x in the given triangle is  [tex]1\frac{3}{5}[/tex]

Answer:

10/27

Step-by-step explanation:

To figure this out, first subtract 8/15 from 6/5.

Before we can do that though, we need a common denominator. The LCM of 5 and 15 is 15. (5 * 3 = 15; 15 * 1 = 15) 8/15 already has 15 has a denominator, so that doesn't need to be modified. 6/5 becomes 18/15 (6 * 3 = 18).

Subtract 8/15 from 18/15 to get 10/15. This simplifies to 2/3.

Now, multiply 2/3 by 5/9 (reciprocal of 9/5). That equals 10/27. There is no need to reduce, as it is already simplified.

Rosemary is driving to Chicago, and she is 84 miles away. She wants to arrive in 1.5 hours. What rate of speed will she have to maintain to arrive in that time?
Group of answer choices

Rosemary needs to maintain 126 mph.

Rosemary needs to maintain 65 mph.

Rosemary needs to maintain 56 mph.

Answers

Answer:

56 mph

Step-by-step explanation:

Process of elimination. 126 mph is much too high because it's more than the distance and they will arrive too early. 65 + 65 ÷ 2 = 97.5, that's more than 84 miles. The reason we divide by 2 is because of the .5. Now all we have is 56 mph. To check, 56 + 56 ÷ 2 = 84

Answer:

56

Step-by-step explanation:

84 / 1.5 = 56
