Answer: $76

Step-by-step explanation:

Stores buy goods from others and sell it at a higher price to make profit. The difference between the price they bought it for and the one they will sell is the markup.

The markup percentage represents that markup in terms of the original cost.

If the price now is 75% higher than the original price, assume the original price to be x.

Expression is:

x + (x * 75%) = 133

x + 0.75x = 133

1.75x = 133

x = 133/1.75

x = $76

Answer:

Step-by-step explanation:

Answer:

Last year there were 550 bison in the heard and this year it is 10% larger.

10% is also 10/100 or 0.10

To find 10% of the heard last year

550 x.0.10 = 55. To find the number in the heard this year add 550 (last year) + 55 (10% growth) = 605 or,

to find how many there are now last years heard size was 100% of the heard or 1.00. To find any percent more add it to 1.00 and multiply by the starting amount.

550 x 1.10 = 605

For the second example.

If there are 550 bison in the heard this year, and this year was a decrease of 10% from last year we can express last year's number like this.

550 = (x - (x * 0.10)) simplify;

550 = 1x - 0.10x

550 = 0.90x

Divide both sides by 0.90

x = 611.11 but it's hard to have 0.11 of a bison so realistically 611 bison last year. Subtract 10% or 61 and you indeed have 550 this year.

Step-by-step explanation:

2log(x)=log(64)

By logarithms properties

[tex]xlog_{a}(b)=log_{a}(b^{x} ) \\[/tex]

log(x²)=log(64)

When you have log or ln in both sites, you delete them and...

x²=64

[tex]\sqrt[]{x^{2} } =\sqrt{64} \\x=8[/tex]

Answer:

245

Step-by-step explanation:

This is a ratio

7/10 = 70% = the kids who picked summer which leaves off as 30% for an unknown season

    7 : 10

245 : 350

The 7 is how many students chose summer, and the 10 is the number of students there are in general

The 245 is the number of students who chose summer, and the 350 is the number of students there are in general

All we had to do was see how many times 10 goes into 350, which is 35 times. So we multiply 10 by 35 and we get 350. Now whatever we do on one side, we need to do it to the other. So 7 times 35 gives us 245. And that's how I know that out of the 350 students there are in total, 245 of them chose summer.

Hope this helped!

Answer:

a. C = $ 10.50x b. 2 persons

Step-by-step explanation:

a. Write an equation to find how many people visited in a hour

Let x be the number of persons admitted in one hour. Since the movie theater charges 10.50 per person for admission, then the total admission fees would be C = charge per person × number of persons = $ 10.50 × x = $ 10.50x.

C = $ 10.50x

b. Solve an equation to find how many people visited in a hour

Given that C = $19.11, and C = $ 10.50x, so,

x = C/($10.50)

substituting C into the equation, we have

x = $19.11/$10.50

x = 1.82

Since we cannot have a decimal number of persons, x is rounded up to the nearest whole number. So,

x = 1.82

x ≅ 2

So, two people visited the theater in one hour.

Answer:

1500yards

Step-by-step explanation:

Distance between two coordinates is expressed as;

D = √(x2-x1)²+(y2-y1)²

Given the coordinates (1,5) and (10, 17)

D = √(10-1)²+(17-5)²

D = √(9)²+(12)²

D = √81+144

D= √225

D = 15 units

Since 1 unit = 100yards

15 units = x

x = 15(100)

x = 1500 yards

Hence the delivery centres are 1500yards apart

Answer:

[tex]\mathrm{P(1)\:}=\frac{1}{5}[/tex]

Step-by-step explanation:

There are simply 5 possible values in the given set. Out of these, only one of these is the number 1. Therefore, the probability a 1 is drawn (P(1)) is [tex]\fbox{$\frac{1}{5}$}[/tex].

P(1) = 0.2

"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."

P(A) = n(A) / n(S)  

where, n(A) is the number of favorable outcomes and n(S) is the total number of events in the sample space.

For given question,

Number on dice = 1, 3, 3, 4, 4

⇒ S = {1, 3, 3, 4, 4}

total outcomes n(S) = 5

Let event A: getting 1 on dice

⇒ n(1) = 1

Using the formula of probability,

P(A) = n(A) / n(S)

⇒ P(A) = 1/5

⇒ P(A) = 0.2

#SPJ2

Answer:

20,640

Step-by-step explanation:

32 lots of 645

so 32×645=20,640

x²=y⇒x=√y

x=√112⇒10.583

x=√448⇒21.166

i’m going to interpret this as (r+5)/3=-16. we multiple both sides by 3 to get (r+5)=48. now we subtract 5 from both sides to get r=43

Answer:

x = 9

Step-by-step explanation:

STEP 1: Find the dilation of RQ to VT

Dilation = 9:12

= 3:4 or 3/4

STEP 2: Apply that dilation to PR to UV

Expression: x-3:18

(x-3 has to equal 3/4 of 18)

18/3 = 6

x-3 = 6

x = 9

This is your final answer.

Answer:

Area of pool = 24x²-43x-56 square feet

Step-by-step explanation:

Given that:

Dimensions of rectangular swimming pool = 3x - 8 and 8x + 7

Area of the swimming pool can be calculated by multiplying the dimensions.

Area of pool = (3x-8)(8x+7)

Area of pool = 3x(8x+7)-8(8x+7)

Area of pool = 24x²+21x-64x-56

Area of pool = 24x²-43x-56

Hence,

Area of pool = 24x²-43x-56 square feet
