Your answer is very close to being correct; however, the true answer is actually $\frac{4x+1}{3x-4}$ without any parenthesis needed around the fraction. Notice how there is no (x) at the end.

Answer:

$\boxed{a.\:\:\:76.3\:in^2}$

Step-by-step explanation:

The figure is made up of a rectangle and two semicircles.

We find the area of the rectangle using the formula;

$Area = l\times w$

$\Rightarrow Area = 8\times 6$

$\Rightarrow Area = 48\:in^2.$

We find the area of one of the semicircles and multiply by 2;

The area of the semicircles

$=2\times \frac{1}{2}\times \pi \times r^2$

We substitute $\pi =3.14$ and $r=3\:in$ to obtain;

$=2\times \frac{1}{2}\times 3.14 \times 3^2$

$= 3.14 \times 9$

$=28.26\:in^2$

The area of the figure is

$=48+28.26$

$=76.26\:in^2$

To the nearest tenth we have;

$=76.3\:in^2$

The correct answer is A

A silk ribbon costs $5.60 for 0.8m. How much does 3.25m of this silk ribbon cost?

Varvara68 [4.7K]

We can first find how much the ribbon cost for 1m by setting an equation.

Let $y be the cost for 1m:

0.8y = 5.60
y = 5.60 ÷ 0.8
y = 7

Now that we know 1m of ribbon cost $7, we can proceed to find how much 3.25m ribbon cost by mutiplying the length with the cost:

7 x 3.25
=$22.75

Therefore the answer is $22.75.

Hope it helps!

Suppose that there are 20 numbers in a data set and that they are all different. How many of the values in this data set are bet

antoniya [11.8K]

Answer:

10 Values

Step-by-step explanation:

We would use a set of data for illustration

Given the set of numbers:

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20

Since we have an even number of data, the median is in between 10 and 11.
