Brooke is a high school graduate and makes $28,150 annually as an office assistant. Jake is acollege graduate and makes $31,380 annually as acustomer service manager at a clothing store. what is the difference in salary after 5 years?

Answers

Quite simple, actually...

So,

Brooke makes $28,150 per year...so..to find 5 years...take..

28,150*5=140,750, after 5 years, Brooke makes this much.

Also, for, Jake..take..

31,380*5=156,900

after 5 years, Jake makes this much.

To see how much Jake earns more than Brooke..take.

156,900-140,750=16,150

Jake earns $16,150 more than Brooke.

A, B and C are collinear and B is between A and C. The ratio of AB to AC is 1:3. If A is at (2,-6) and B is at (3,-1) what are the coordinates of point C

Answers

Answer:

The coordinate of C is (5,9)

Step-by-step explanation:

A, B and C are collinear and B is between A and C.

The ratio of AB to AC is 1:3

If A is at (2,-6) and B is at (3,-1)

AB:AC = 1:3

B is between A and C

AB:(AB+BC) = 1:(1+2)

Therefore, AB:BC = 1:2

Let the point C (a,b)

Using section formula:

$x\rightarrow (mx_2+nx_1)/(m+n)$

$y\rightarrow (my_2+ny_1)/(m+n)$

where,

$m\rightarrow 1$

$n\rightarrow 2$

$x_1m\rightarrow 2$

$y_1\rightarrow -6$

$x\rightarrow 3$

$y\rightarrow -1$

Substitute into formula and solve coordinate point C

$3=(1\cdot a+2\cdot 2)/(1+2)$

$3=(a+4)/(3)$

$a=5$

$-1=(1\cdot b-6\cdot 2)/(1+2)$

$-1=(b-12)/(3)$

$b=9$

Hence, The coordinate of C is (5,9)

Answer:

(5, 9)

Step-by-step explanation:

The distance between A and B is 1/3 the distance between A and C.

x coordinates:

3 − 2 = 1/3 (x − 2)

1 = 1/3 (x − 2)

3 = x − 2

x = 5

y coordinates:

-1 − (-6) = 1/3 (y − (-6))

5 = 1/3 (y + 6)

15 = y + 6

y = 9

The coordinates of point C are (5, 9).

1. Simplify $(8)/(32)$ by divide both numbers by 4 and you'll get the answer as C. C is correct
2. Unit rate is expression that has quantity of 1, numerator are often dollars or units like miles, km, meters... and denominator often pounds, kg, gram, liters ... So C is correct answer for your question:)
3. To find total money in the bag, 14 + 6 = 20 coins, there are 6 nickels so the expression is $(6)/(20)$ or $(3)/(10)$ in lowest terms.
4. Multiply diagnally 12 × 6 = 72, 72÷ 9 = 8, so the answer is A.

Mrs. Harrison used 16 ounces of dark chocolate while baking. She used 2/5 of the chocolate to make some frosting and used the rest to make brownies. How much more chocolate did Mrs. Harrison use in the brownies than in the frosting

Answers

¹⁶/₅ or 3 ¹/₅ or 3.2 ounces.

Further explanation

Given:

Mrs. Harrison used 16 ounces of dark chocolate while baking.
She used ²/₅ of the chocolate to make some frosting.
She used the rest to make brownies.

Question:

How much more chocolate did Mrs. Harrison use in the brownies than in the frosting?

The Process:

From the information above, we made a suitable diagram as follows:

$\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot} = 16 \ ounces$

Hence, one part equal to $(16)/(5) \ ounces$ .

She used $(2)/(5)$ of the chocolate to make some frosting, meaning two of five parts of the chocolate.

$\boxed{\cdot}\boxed{\cdot}$

And she used the rest, that is, $(3)/(5)$ of the chocolate to make brownies, meaning three of five parts of the chocolate.

$\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}$

Finally, let us find out how much more chocolate did Mrs. Harrison use in the brownies than in the frosting. Before that, prepare in the form of a fraction of the part in question.

$\boxed{ \ = (3)/(5) - (2)/(5) \ }$

$\boxed{\boxed{ \ = (1)/(5) \ }}$ or one of five parts of the chocolate.

We declare this fraction into ounces by multiplying it by 16 ounces.

$\boxed{ \ = (1)/(5) * 16 \ ounces \ }$

$\boxed{\boxed{ \ (16)/(5) \ or \ 3(1)/(5) \ or \ 3.2 \ ounces \ }}$

Thus Mrs. Harrison used 3.2 ounces more chocolate in brownies than in the frosting.
