Answer:

X=10

Step-by-step explanation:

The two triangles are similar since each triangle is the same shape of right triangle but different sizes. To find x, write a proportion between two equal ratios of side lengths.

Solve by cross multiplying.

28(3x) = 20(4x+2)

84x = 80x + 40

4x = 40

x=10

Answer:

x=10

Step-by-step explanation:

The two triangles are similar since each triangle is the same shape of right triangle but different sizes. To find x, write a proportion between two equal ratios of side lengths.

\frac{28}{20}=\frac{4x+2}{3x}

Solve by cross multiplying.

28(3x) = 20(4x+2)

84x = 80x + 40

4x = 40

x=10

Number 4 is C because when you do 28 times 5 your get 140 then you do 140 divided by 20 to get 7 when you do proportions to find the missing number you cross multiply with the numbers there and divide with the number that is across from the missing
Number 5 is $6 because to find the missing number you have to see which way makes sense you could do 4 divided by 3 but you get a really long number so if you do 3 divided by 4 you get .75 and you get .75 for all cost is usually the y-axis so you do y divided x so then do .75 times 8 to get the answer
Number 6 to plot them you just go in the middle of the line for the first because it is not directly 2
Number 7 to change a fraction to decimal do the numerator divided by denominator even if the denominator is bigger so 6 divided by 25 is .24 for decimal form to get the percent move the decimal point two places to the right so it will be 24%

Answer:

570 miles

Step-by-step explanation:

304/4 is how many miles it travels in each hour and if its 7.5 hours then you multiply that by each mile it takes each hour.

304/4 = 76

76 x 7.5 = 570

Estimate the following sum by clustering.
Kryger [21]
The answer would be 60. By rounding, 14.2=14; 15.51=16; 14.99=15; 15.8=16.
14+15+16+16=61
Rounding: 61=60

A farmer planted 3/4 of an acre of land with 2 types of wheat. If she planted an equal amount of each type of wheat, how many ac
VMariaS [17]

Answer:

\frac{3}{8} acres.

Step-by-step explanation:

We have been given that a farmer planted 3/4 of an acre of land with 2 types of wheat. She planted an equal amount of each type of wheat. We are asked to find the number of acres in which farmer planted of each type of wheat.

To find the number of acres in which farmer planted of each type of wheat, we will divide total land by 2 as:

\text{Number of acres of each type of wheat}=\frac{3}{4}\div 2

Let us represent 2 as a fraction.

\text{Number of acres of each type of wheat}=\frac{3}{4}\div \frac{2}{1}

Now, we will convert the division problem to multiplication problem by flipping the 2nd fraction as:

\text{Number of acres of each type of wheat}=\frac{3}{4}\times \frac{1}{2}

\text{Number of acres of each type of wheat}=\frac{3\times 1}{4\times 2}

\text{Number of acres of each type of wheat}=\frac{3}{8}

Therefore, the farmer planted \frac{3}{8} acres of each type of wheat.
