The greatest common factor of two numbers is 4. The sum of the numbers is 76. What are the two numbers? A. 38 and 38 B. 12 and 64 C. 18 and 58 D. 32 and 40

Answers

Answer: B. 12 and 64

Step-by-step explanation:

Option A is incorrect because the highest common factor for both numbers would be 38 not 4.

Option B:

Factors of 12 are: 1, 2 , 3, 4, 6, 12

Factors of 64 are: 1, 2, 4, 8, 16, 32 and 64.

Highest factor of both is 4 and they both add up to 76 so option B must be correct.

Malcolm Little High School has sopho- mores, juniors, and seniors, but no freshmen. The ratio of sophomores to juniors is 5 to 4, and the ratio of juniors to seniors is 3 to 2. If there are 300 sophomores, how many seniors are there?

Answers

Answer:

161 seniors

Step-by-step explanation:

According to the problem, given data are as follows:

Total number of sophomores = 300

Sophomores to junior ratio = 5:4

So, Number of Juniors = 300 ×  (4 ÷ 5)

= 240

Now, Juniors to senior ratio = 3:2

So, we can calculate the number of seniors by using following method:

Number of seniors = 240 × ( 2 ÷ 3)

= 240 × 0.67

= 160.8 or 161

Ella was paid an 11 percent commission on the pair of shoes that she sold. The department store had paid $25 wholesale for the shoes and had marked up the price by 40 percent to the selling price. How much did Ella earn for the sale?

Answers

Answer:

The answer is B. $3.85.

Step-by-step explanation:

This is because, first if we get the percentage that the shoes were marked up by, we get that they were marked up to $35, because 40% of $25 is $10 and $25 + $10 = $35.

Then, we find the percentage of $35 that she earned. In order to do this, we see what 11% of $35 is. We get $3.85, because 10% of $35 is $3.50, and 1% of $35 is $0.35. $3.50 + $0.35 = $3.85.

This is why the answer is B. $3.85.

Answer:

F is inversely proportional to d squared. When F = 16 , d = 3 Work out d (positive value rounded to 2 DP) when F = 8

Answers

Answer:

d = 3√2

Step-by-step explanation:

find the constant of variation ('k'):  F = k/d²

16 = k/3²

16 = k/9

k = 144

8 = 144/d²

d² = 144/8

d² = 18

d = √9 · √2

d = 3√2

Find the area of the shaded regions. Give your answer as a COMPLETELY simplified EXACT VALUE OF π (no approximations).

Answers

Answer:

128π - 8

Step-by-step explanation:

Hypotenuse length:

2π(√32/2)²  = (√32)² × 2² = 2π × 32 × 4 = 2π × 128

256π is the area of the circle

Area of shaded region = area of circle/2 - area of triangle

256π/2 = 128π

128π - 16/2

how do i solve 13 + a/11 = 7

Answers

Answer:

a = -66

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

13 + a/11 = 7

Step 2: Solve for a

Subtract 13 on both sides:                     a/11 = -6Multiply 11 on both sides:                       a = -66

Step 3: Check

Plug in a into the original equation to verify it's a solution.

Substitute in a:                     13 - 66/11 = 7Divide:                                   13 - 6 = 7Subtract:                               7 = 7

Here we see that 7 does indeed equal 7.

∴ a = -66 is the solution to the equation.

Answer:

If you mean [tex]\frac{13+a}{7}=7[/tex] then the answer is [tex]a=36[/tex].

If you mean [tex]13+\frac{a}{7} =7[/tex] then the answer is [tex]a=-42[/tex].

Step-by-step explanation:

Step-by-step explanation:

Lucy and Greg each want to buy a bicycle. Lucy has already saved $35 and plans to save $10 per week. Greg has $26 and plans to save $13 per week. How many weeks will it take for Lucy and
Gregory to have the same amount of money saved? How much money will they have saved?

Answers

By week 3 they will both have $65

Answer:

3 weeks

65 dollars

Step-by-step explanation:

Alright to answer this question we have to set up an equation. For greg the equation is y=13x+26 and for lucy the equation is y=10x+35. y is total amount of money saved and x is number of weeks. Since we want them to each of the same amount of money we set up the equations to be 10x+35=13x+26

then we want to get the constant and the variables alone on different sides of the equal sign so we first subtract 26 from each side to get 10x+9=13x. next we want to subtract 10x from each side and then we end up with 3x=9. Finally we divide 3 from each side to get x=3, We have answered the question to how many week it will take them to save the same amount of money but not the other part. To find out how much money they will both have in 3 weeks we plug in 3 to x. 10(3)+35 which is equal to 65. They will both have 65 dollars in three weeks
