Answer:

d + 85

Step-by-step explanation:

Look at it like this,

suppose you have 1 DVD, and the mother buys 85 DVDs then you have 1 + 85 = 86 DVDS

or when you have 2 DVDs, then you have 2 + 85 = 87 DVDs afterwards.

notice that you always take the number of DVDs you already have, and add 85 to it.

d is just a number, but you just don't know it yet. you can change d by any number, and you know d+85 is the number of DVDs afterwards

7. You have $367.50 after two years.

Start by converting 2.5% into a decimal (divide by 100) and multiplying by 350 to find the rate of interest per year.

350(0.025) = 8.75

Since it's for two years, multiply by two.

8.75 x 2 = 17.5.

Add it on to he original, and we have

350 + 17.5 = 367. 5, or $367.50 when converted back to money.

8. The annual interest rate is 2.4%

find the interest rate per year:

120/2.5 = 48 dollars per year. this is the interest amount, we want to find the interest rate. To do this, find what % of 2000 that 48 is equal to.

Set up a system of equations and cross multiply.

[tex]\frac{48}{2000} = \frac{x}{100}[/tex]

2000x = 48(100) > 2000x = 4800

2000/2000x = 4800/2000 > x = 2.4

So, the interest rate is 2.4%.

9.  the interest paid is $300 after six months, and $600 after a year.

Find the interest rate, similar to problem 7.

3000 x 0.2 = 600. This means the interest paid is $600 a year. In six months, the total will be half, or $300.

10. four years.

Find interest rate.

200(0.035) = $7/year

Remember that value. Subtract needed from current.

228 - 200 = $28.

So, we have an interest rate of $7 a year and we need $28. Normally, we'd solve using an expression, but in this case we can use simple multiplication. Knowing that 7 x 4 = 28, We can decide that it will take four years.

Answer:

At least 39200 students.

Step-by-step explanation:

Given that there are 196 countries in the world, and each country would have at least 200 students in a university.

For each country to have at least 200 students in the university, then;

Number of students enrolled in the university = number of required students x number of countries

                                      = 200 x 196

                                      = 39200

At least, 39200 students must be enrolled in the university. Provided that the admission procedures are conditioned for the purpose.

Answer:Given : Triangle ABC is transformed to triangle A′B′C′

To Find : Which equation shows the correct relationship between the measures of the angles of the two triangles

a  The measure of ∠ABC = The measure of ∠A'B'C'

b  The measure of ∠ABC = The measure of ∠B'C'A '

c  The measure of ∠BCA = The measure of ∠A 'B 'C '

d  The measure of ∠BCA = The measure of ∠C 'A 'B '

Step-by-step explanation:

Triangle ABC is transformed to triangle A′B′C′,

ΔABC  ≅ ΔA'B'C'

Hence

∠ABC = ∠A'B'C'

∠BCA = ∠B'C'A '

The measure of angle ABC = The measure of angle A prime B prime C prime

The measure of ∠ABC = The measure of ∠A'B'C'

option a is correct

Answer:

144

Step-by-step explanation:

The ratio of men to women working for a company is 8 to 5.

Total men and women working as per the ratio is 8+5 = 13

So the ratio of men to total  is  

the ratio of women to total  is  

there are 234 employees total

To find the number of men works , we make a proportion

Cross multiply it

8 * 234 = 13x

1872 = 13x

Divide by 13 on both sides

x= 144

Answer:

87 men

145 women

Step-by-step explanation:

8 to 5

8x+5x=234

8x=234

x=234/8

x=~29

3*29=87 men

5*29=145 women

Answer:

37

Step-by-step explanation:

Let x be the smaller number. 2x+7 is the larger number. Their difference is 22:

x+22=2x+7

x=15

So the smaller number is 15 and the larger number is 2(15)+7=37.

Answer:

Five cups of flower

Step-by-step explanation:

2 cups makes 10 so 4 would make 20 and 5 would make 25.

Answer:

so the answer would be 3

Step-by-step explanation:

Lets take a look she swam for 45 minutes if we do

add 15, 3 times we get 45

15 + 15 +15 = 45

We can also do 3 x 15 which also equals 45

so its 3

Step-by-step explanation:

Set D is not a functions. Functions are defined as each x having only 1 y value associated with it. 2 in the x column has two values associated with it: 1 and 2

D is not a function.

= 16 , 18 , 20 , 22 or 24

rather go with 16
