Answer:

Step-by-step explanation:

(x − 25) = 7

+25 +25

x = 32

5x + 15 = 28

-15 -15

5x = 13

/5 /5

x= 13/5

(4x + 15)=24

-15 -15

4x = 9

/4 /4

x= 2 1/4

1) 1/5 (x-25) = 7
1/5x - 5 = 7
Add five to both sides
1/5x = 12
Divide both sides by 1/5
x = 60

The diameter of your bicycle wheel is 20 inches. How far will you move in one turn of your wheel?

Helen [10]

To do this, You must know the formula. D=3.14l*r Or, Distance=3.14length*revolutions
3.14 is pi.
Revolutions are the turns of a wheel.
Plug in your numbers. D=3.14*20*1
D=62.8 inches

How many milliliters of syrup are in a 100-ml sample containing 6.55 g of syrup per 20 mL if the syrup's specific gravity is 1.3

sashaice [31]

Answer:

25 milliliters

Step-by-step explanation:

Given:

volume of sample = 100 ml

Syrup present in sample = 6.55 g per 20 mL

Therefore in 100 mL, amount of syrup present = $\frac{\textup{6.55}}{\textup{20}}\times100$

amount of syrup present in 100 mL sample = 32.75 grams

Now,

Specific gravity of the syrup = 1.31

also,

Specific gravity of the syrup = $\frac{\textup{Density of syrup}}{\textup{Density of water}}$

1.31 = $\frac{\textup{Density of syrup}}{\textup{1 g/mL}}$

Density of syrup = 1.31 g/mL

also,

Density = $\frac{\textup{Mass}}{\textup{Volume}}$

therefore,

1.31 = $\frac{\textup{32.75}}{\textup{Volume of syrup in the sample}}$

Volume of syrup in the sample = $\frac{\textup{32.75}}{\textup{1.31}}$

Volume of syrup in the sample = 25 milliliters

One-third of the dairy cattle on a farm are in the barn. Three-fifths of the beef cattle are in the barn. There are 30 dairy cat

Korolek [52]

Let

d = the total number of dairy cattle

b = the total number of beef cattle

2/3 of the dairy cattle on a farm are in the barn, and we know that 24 dairy cattle are in the barn thus:

(2/3)d = 24

d = 36 dairy cattle

1/4 of the beef cattle are in the barn and there are 16 beef cattle in the barn thus:

(1/4)b = 16

b = 64 beef cattle

64 - 36 = 28

There are 28 more beef cattle on the farm than dairy cattle.

AnnyKZ [126]

Answer:

4900

Step-by-step explanation:

If 55% of workers are women, then 45% are not; therefore, we need to answer the following:

2205 is 45% of what number?

2205=45%x

2205/.45=x

4900=x
