Step-by-step explanation:

Multiply the Price Percentage by the Original Price

Multiply the original price and the percentage that represents the sale price; the result is the sale price of the blazer in dollars: $90 × 0.7 = $63. So if the blazer is on sale for 30 percent off, you'll pay the remaining 70 percent of the price, which is $63.

Answer:

x=-1

Step-by-step explanation:

-4x=y+8

-8-4x=y

7x-2y=1

7x-2(-8-4x)=1

7x+16+8x=1

15×+16=1

15x=-15

x=-1

Answer:

We have the equation A*C = A

Now, as both sides of the equality are the same thing, we can do the same operation to both sides and the equality will remain true.

We can divide both sides by A and get:

(A*C)/A = A/A

C = 1

So here we finded the value of A.

If A and C are matrices, then C is the identity matrix.

Answer:X+9=11

9-9|11-9

X=2

Step-by-step explanation:When the beginning number is unknown we use “x” to be a place holder. If she got 9 more books we would add 9 to the equation. Finally if 11 is the total, the end of the equation would equal 11.

Answer:

2nd degree trinomial

Because they have three terms ( x ,y and Z ) and highest degree is 2.

Answer:

B.

Step-by-step explanation:

It is very possible.

Make the value of apple x and the value of orange y.

5x + 4y = 10

5x + 5y = 11

-y = -1

y = 1

x = 1.2

Now just match them up.

Yes; They should charge $1.20 for and apple and $1.00 for an orange.

Answer:

b

Step-by-step explanation:

Answer:

a) 12 1/2 cm

b) 5 1/4 cm

Step-by-step explanation:

The piece of string is 24 cm long.

It is cut in three pieces.

Let the length of the first piece be x.

The second piece is twice as long as the first. This means that the length of the second piece is 2x.

The third is 1 cm shorter than the first. This means that the length of the third piece is x - 1

Therefore:

x + 2x + x - 1 = 24

4x - 1 = 24

4x = 25

x = 25 / 4 = 6 1/4cm

Therefore, the length of the second piece will be:

2 * 25/4 = 25/2 = 12 1/2 cm

The length of the third piece will be:

6 1/4 - 1 = 5 1/4 cm

Answer: Try 8 or C because you either add or subtract the exponents but 2 isn’t there so try 8

Answer:

Acute

Step-by-step explanation:

If the angle is already acute, and the line PQ is inside the acute angle. The new angle has to be less than the first angle and is therefore acute as well.

Answer:

Graph is below

Step-by-step explanation:

I graphed the point on the graph below.

The graph that has the coordinate ( [tex]-4\frac{1}{2}[/tex] , [tex]2\frac{1}{2}[/tex]) is given.

Coordinates are a collection of numbers that aid in displaying a point's precise location on the coordinate plane.

First we transform fraction to improper fraction.

( [tex]-4\frac{1}{2}[/tex] , [tex]2\frac{1}{2}[/tex])

= (-7/2 , 5/2)

Then further simplified to decimals,

( [tex]-4\frac{1}{2}[/tex] , [tex]2\frac{1}{2}[/tex])

= (-3.5 , 2.5)

Now to draw in the graph take x = -3.5 and y = 2.5

And draw lines from both of the point and see if there is any intersecting point.

The intersecting point is coordinate point.

Therefore, the intersecting point is coordinate point.

Complete question:

A circle has a radius of 3 and a central angle of 340 degrees, what is the arc length? Round to the nearest tenth place.

Answer:

length of arc ≈ 17.8 (to the nearest tenth)

Step-by-step explanation:

To find the length of the arc we use the formula for finding length of an arc.

length of arc = ∅/360 × 2πr

where

∅ = central angle

r  = radius

∅ = 340°

r = 3

length of arc = ∅/360 × 2πr

length of arc = 340/360 × 2 × π × 3

length of arc = 340/360 × 6π

length of arc = 2040π/360

length of arc = 204π/36

length of arc = (204 × 3.14)/36

length of arc = 640.56/36

length of arc = 17.7933333

length of arc ≈ 17.8 (to the nearest tenth)

Answer:

It is 17/3 pi

Step-by-step explanation:

I know this is already answered, but I have this same question on Khan Academy, and I entered the number on the answer here, but it says the length of the arc is 17/3 pi. And, yes, you can put the 'pi' symbol in Khan, it accepts it as an answer.

Step-by-step explanation:

Given: A triangle ABC was rotated 90 degrees counterclockwise

To find: coordinates of the point B

Solution:

A triangle is three - dimensional figure that has three sides, three vertices and three angles.

Counterclockwise refers to the direction opposite to the direction of movement of hands of the clock.

As triangle ABC was rotated 90 degrees counterclockwise about the origin, point B is [tex](-1,2)[/tex]

Answer:

4x - 1

Step-by-step explanation:

Given the area

16x² - 8x + 1

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 16 × 1 = 16 and sum = - 8

The factors are - 4 and - 4

Use these factors to split the x- term

16x² - 4x - 4x + 1 ( factor the first/second and third/fourth terms )

= 4x(4x - 1) - 1(4x - 1) ← factor out (4x - 1) from each term

= (4x - 1)(4x - 1)

= (4x - 1)²

The area of a square = s² ( where s is the length of the side )

s² = (4x - 1)², thus

s = 4x - 1 ← length of side of square

Answer:

4.50 = ?

To the nearest hundredth

Answer:

The first set (A)

Step-by-step explanation:

The five inputs are {-12, -3, 0, 3, 12}.  The first set (A) includes all five of these inputs and a single output for each of them:  {(-12, -18), (-3, -3), (0, 2), (3, 7), (12, 22).

Using the given function,  the correct set of ordered pairs for the following domain values is A; {(-12, -18), (-3, -3), (0, 2), (3, 7), (12, 22).

The domain of a function is defined as the set of all the possible input values that are valid for the given function. The range of a function is defined as the set of all the possible output values that are valid for the given function.

The five inputs are given as;

{-12, -3, 0, 3, 12}

WE can see that first set (A) includes all five of these inputs and a single output for each of them;

{(-12, -18), (-3, -3), (0, 2), (3, 7), (12, 22).

Therefore, Using the given function,  the correct set of ordered pairs for the following domain values is A; {(-12, -18), (-3, -3), (0, 2), (3, 7), (12, 22).

Answer:

u = 5

Step-by-step explanation:

→Distribute the 3 to (-3u - 5):

4u = 16u - 9u - 15

→Add like terms:

4u = 7u - 15

→Subtract 4u from both sides:

0 = 3u - 15

→Add 15 to both sides:

15 = 3u

→Divide both sides by 3:

5 = u
