I need help I don’t get how to solve it plsss help me

Answer:

The cost of the sweater would be $17.28

Answer: 4(-1)^3 (2)^2=4

So you would first substitute the x for -1

Then you would substitute the y for 2

Giving you- 4 (-1)^3 Times (2)^2 which would equal 4

Hope this helps :) Im learning this too in math lol

Answer:

26.67%

Step-by-step explanation:

In the Seventh grade Rachel read 15 books in the 8th grade she read 19 books what is the percent of change of books read

The formula for Percent change =

New value - Original value/Original value × 100

New value = 19 books

Original value = 15 books

= 19 - 15/15 × 100

= 4/15 × 100

= 26.67%

The percent change of book read= 26.67%

Answer:

$1.10

Step-by-step explanation:

The first two stickers cost $0.8. The thrird one will cost 75% of the cost of one sticker. To find the answer, you multiply 0.75 (0.75 is 75% as a decimal) by 0.4 to get 0.3. $0.3 plus $0.8 equals $1.10.

Answer:

7%

Step-by-step explanation:

(15/220) x 100 = 6. 8182 = 7%

to convert to percentage multiply by 100

To convert to the nearest whole number, look at the first number after the decimal. If it is greater or equal to 5, add 1 to the number after the decimal. 8 is greater than 5, so add one to 6

Answer: Length = 15 meters

Width = 2 meters

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

Area of a rectangle = l × w

where l = length

w = width

Therefore,

2l + 2w = 34 ...... i

l × w = 30 ........ ii

From equation i

2l + 2w = 34

Divide through by 2.

l + w = 17 ...... iii

Then, l = 17 - w ........ iv

Put equation iv into ii

l × w = 30

(17 - w) × w = 30

17w - w² = 30

w² - 17w + 30 = 0

w² - 15w - 2w + 30 = 0

w(w - 15) - 2(w - 15) = 0

(w - 2) = 0

w = 0 + 2 = 2

w - 15 = 0

w = 0 + 15 = 15

Length = 15 meters

Width = 2 meters

Note: The height of the room must be 3 m instead of 3 cm because 3 cm is too small and it cannot be the height of a room.

Given:

Perimeter of the floor of a room = 18 metre

Height of the room = 3 metre

To find:

The area of 4 walls of the room.

Solution:

We know that, the area of 4 walls of the room is the curved surface area of the cuboid room.

The curved surface area of the cuboid is

[tex]C.S.A.=2h(l+b)[/tex]

Where, h is height, l is length and b is breadth.

Perimeter of the rectangular base is 2(l+b). So,

[tex]C.S.A.=\text{Perimeter of the base} \times h[/tex]

Putting the given values, we get

[tex]C.S.A.=18\times 3[/tex]

[tex]C.S.A.=54[/tex]

Therefore, the area of 4 walls of the room is 54 sq. metres.

Answer:

sin2θ = - [tex]\frac{24}{25}[/tex]

Step-by-step explanation:

Given

cosθ = [tex]\frac{3}{5}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex] and in fourth quadrant

Then this is a 3- 4- 5 triangle with opposite side = 4

sinθ < 0 in fourth quadrant, then

sinθ = - [tex]\frac{opposite}{hypotenuse}[/tex] = - [tex]\frac{4}{5}[/tex]

Using the double angle identity for sine

sin2θ = 2sinθcosθ

          = 2 × - [tex]\frac{4}{5}[/tex] × [tex]\frac{3}{5}[/tex] = - [tex]\frac{24}{25}[/tex]

Answer:

3

Step-by-step explanation:

3x-3=2x

3x-2x=3

x=3

Answer:

x=3

Step-by-step explanation:

3x - 3 = 2x

-3x -3x

-3 = -x

The x cannot be a negative so you divide both sides by -1 and then the answer becomes x=3

[tex]80\pi \frac{rad.}{sec.} [/tex]

Step-by-step explanation:

You need to calculate the circumference of this wheel to determine how far it travels with each revolution.

First, you need to know the diameter of a circle, which is the length of a straight line drawn through the circle.

You need to calculate the circumference of this wheel to determine how far it travels with each revolution.

First, you need to know the diameter of a circle, which is the length of a straight line drawn through the circle.

The magic number here is pi, which is roughly 3.14159265. The digits to the right of the decimal point continue infinitely.

Dividing a circle’s circumference by pi will give you a circle’s diameter.

Multiplying a circle’s diameter by pi will give you a circle’s circumference.

Answer:

10x=y

Step-by-step explanation:

Divide your outputs by your inputs. In other words, divide 20 by 2, 50 by 5, and 70 by 7. These all equal 10. Therefore, 10 times x will equal y.
