Answer:

368 milliliters.

Step-by-step explanation:

Compound A + Compound B = 1 drug

4 + 7 = 1 drug

11 milliliters = 1 drug, so 1012 milliliters = 92 drugs

Multiply the compounds by the amount of drugs, e.g.

4 x 92 = 368 ( Compound A )

7 x 92 = 644 ( Compound B )

368 + 644 = 1012

368 milliliters of Compound A are needed to make 1012 milliliters of the drug.

Hope this helps :)

James wants to construct a regular hexagon inscribe in a circle with center O and diameter PQ

Brums [2.3K]

Answer:

B. Place the compass at P and draw an arc of length OP across the circle.

Below is the diagram for help.

Step-by-step explanation:

We are given with an already constructed circle of diameter $PQ$ and $OP$ as radius.

To draw a regular hexagon(six-sided), we need to make first cut on the circle of an arc equal to radius of the circle taking any point of the diameter as center

So here, We will consider $P$ as a center and take an arc of length $OP$ and make a cut on the circle.

This would be the first step and James need to repeat the same steps by considering the newly formed cut as center each time.

Use the information in the table. You are making a circle graph showing the total number of successful United States space launc

timama [110]

Answer:

52.9°

Step-by-step explanation:

step 1

we know that

The total number of successful United States space launches that happened in the years 1957-1995 is equal to

$15+470+258+153+146=1,042$

step 2

The numbers of successful United States space launches that happened in the years 1980-1989 is equal to

$153$

step 3

The percentage of successful United States space launches that happened in the years 1980-1989 is equal to

$\frac{153}{1,042}(100)=14.68\%$

step 4

Find out the measure of the central angle you would draw in a circle graph to represent the number of successful United States space launches that happened in the years 1980-1989

we know that

In a circle, 360 degrees represent the 100%

using proportion

Find out the measure of the central angle by a percentage of 14.68%

$\frac{360^o}{100\%}=\frac{x}{14.68\%}\\\\x=360^o(14.68\%)/100\%\\\\x= 52.9^o$
