Find common denominators. What you do to the denominator, you do to the numerator.

(2/5)(7/7) = 14/35

(3/7)(5/5) = 15/35

14/35 - 15/35 = -1/35

If you meant to put addition, then your answer will be D) 29/35.

14/35 + 15/35 = 29/35

The correct answer is D. 29/35 because you keep, change, flip

3/7 +2/5 =?

= (3*5)+(2*7) times 7*5

= 29/35

Hope this helps!! :) Mark me brainliest :)

kobusy [5.1K]

Answer:

All go to Sweden.

Explanation:

The two countries Germany and Sweden both can produce furniture and steel. Germany can produce one unit of steel or furniture in 12 days while Sweden can make one unit of steel in 15 days and one unit of furniture in 10 days. Germany has no advantage from the trade since it can produce both the goods in same time. Therefore all of the trade gain would belong to Sweden.

Answer: B

The marginal propensity to save will remain unchanged in each of the countries.

Explanation:

Marginal propensity to consume (MPC) is the percentage of increase or decrease in income that goes to consumption

Marginal propensity to save (MPS) is the percentage of increase or decrease in income that goes into savings. It can also be expressed as:

1 - MPC

Average propensity to save measures the level of saving at a given level of income.

The marginal propensity to save measures changes in savings relative to changes in income but the income remains unchanged here, the MPS also remains unchanged.

PLZZZ HELP, i have limited time and i will give brainliest.

Answer:

Q1. Selena will have earned $ 25.00 in interest by the end of the year.

Since interest paid is 5% in simple interest, we can calculate that by using the formula:

$SI = (P)(r)(t)$

$SI = (500)(0.05)(1) = 25$

Q2. The balance in Suki's account at the end of two years will be $866.2854.

This means that she will have earned $66.2854 in interest.

Since interest is compounded quarterly, Suki will receive interest for 8 periods. The formula for compound interest with more than one interest period per year is:

$\mathbf{A = (P)*(1+(\frac{i}{m})^{n*m}}$

where

A is the amount at the end of the period

P is the principal

i is interest rate per annum

m is number of compounding periods in a year

n is number of years

Substituting the values in the formula above we get,

$A = (800)*(1+(\frac{0.04}{4})^{2*4}$

$A = (800)*(1.01)^{8}$

$\mathbf{A = 866.2853645}$

Now, we calculate the interest earned by doing \mathbf{CI = A -P}.

$\mathbf{CI = 866.2854- 800 = 66.2854}$

Q3. It will take 18 years for the money to double to $100.

Since we need to use the rule of 72, we'll divide 72 by the interest rate to determine the number of years needed to double the investment's value.

So, the number of years is $\frac{72}{4} =18$ .
