Kenzie can buy 48 Scrunchies

Step-by-step explanation:

You have to divide 3 by 20. (3/20) Which is also 1.5/10 and as a decimal, that is 15 cents. So one scrunchie is equivalent to 15 cents, which means how many times can you take .15 from 7.25 is how many scrunchies she can buy. So how many times does .15 go into 7.25? The answer is 48.3(repeating). So you have to round it down because if you round it up she needs more money.

Answer: 20.41

Step-by-step explanation: step 1: (10.80 * 0.65) + 10.80 = 17.82

step 2: (10.80 * 0.24) + 17.82 = 20.41

Answer:

$84

Step-by-step explanation:

1. If 20% is marked off, then you are selling it for 80%.

2. 455 * 80% = 364

3. Since you are finding the cost markup from 280, then 364-280=84

Answer:

D

Step-by-step explanation:

gradient is change in y/change in x

gradient of UV = 14-8/12+4=3/4

use equation y=mx+c where y is the y coordinate, m is the gradient, x is the x coordinate and c is the y intercept

use one of the coordinates of U or V, I'll use (4,8)

[tex]y = mx + c[/tex]

[tex]8 = \frac{3}{4} (4) + c[/tex]

[tex] 8 = 3 + c[/tex]

c is 5

the equation for UV is

[tex]y = \frac{3}{4} x + 5[/tex]

insert each X coordinate given in the question to see if it gives the same y coordinate

when x is 20, y is also 20 so the answer is D

Answer:

[tex]\sqrt19[/tex]

Step-by-step explanation:

First we solve for the biggest triangle: using the Pythagorean theorem, (a^2 + b^2 = c^2) we put in the sides,

9^2 + b^2 = 10^2.

solve, 81 + b^2 = 100

then we subtract 81 from both sides. b^2 = 19, and the answer is [tex]\sqrt 19[/tex].

Now we know what the third side is, which is the hypotenuse for the smaller triangle, so we use the Pythagorean theorem again.

4^2 + x^2 = 19.

Solve

16 + x^2 = 19

Subtract 16 from both sides

x^2 = 19

and finally, we take the square root of both sides

x = [tex]\sqrt19[/tex]

Answer:

$700

Step-by-step explanation:

25% = 1/4

the sales would be 100% or 4/4

So if commission rate is 1/4, to find the sales we multiply this by 4:

$175*4= $700

The sales would amount to $700

Hope this helps :)

Answer:

y=x-32

Step-by-step explanation:

y=mx+b where m is the slope and b is the y-intercept.

slope=change in y/change in x

=5/5

y=5x+b --> choose a random point

(7,3) ---> 3=5(7)+b=35+b

b= -32

y=x-32

Answer:

7 to the power of 7 ( which is 823,543 )

Step-by-step explanation:

Why? well if 4+3 is 7 the exponent would be 7 to because if you look carefuly it says with an exponent of 2 + 5 and 2 + 5 is 7 so your exponent is 7.

I hope This is right!

In this exercise we have to use the conditions given in the statement, that is, when adding the extreme pairs they must give the middle number, so the only number that follows this condition is:

The next year to have to same property will be 2307

are analyzing the condition given in the statement and the example we can buy as follows:

[tex]1978 \rightarrow 19+78= 97 \\2307 \rightarrow 23+07= 30[/tex]

so the year 2307 corresponds to the conditions given in the statement.

Answer:

A. 139,799,000 square miles

B. 57,101,000 square miles

Step-by-step explanation:

71% ÷ 100 = 0.71

0.71 x 196,900,000 = 139,799,000

100 - 71 = 29

29 ÷ 100 = 0.29

0.29 x 196,900,000 = 57,101,000

another way; knowledge of A

196,900,000 - 139,799,000

= 57,101,000

Answer:

kenzie can only buy 2 sets of scrunchies unless she can buy half then it would be 2.5.

Step-by-step explanation:

20 scrunchies = $3.00 meaning= $3.00+$3.00 = 6 dollars. Anymore would be over the limit of money she would be able to use for the scrunchies.

Answer:

40°

Step-by-step explanation:

According to the Triangle Sum Theorem: The sum of the measures of the angles in a triangle will add up to 180°.

So with this, you need to add 70° and 70°.

You get 140°

Then to find the last angle, you will subtract the 140° by 180°.

180°-140° = 40°

Hope this helped! :)

Answer:

 40

Step-by-step explanation:

First you add 70 and 70 together to get 140 then minus it by 180.

Then you will get 40 degrees as your answer.
