Answer: 24

Step-by-step explanation:

Number of marbles in jar = 32

Let blue marbles be represented by b.

Since there are three times as many green marbles as blue. This means that green will be = 3 × b = 3b

We then add them together. This will be:

3b + b = 32

4b = 32

b = 32/4

b = 8

There are 8 blue marbles

Since green is 3× blue. Therefore,

Green = 8 × 3 = 24 marbles

love history [14]

Step-by-step explanation:

5x + 7 - 2( - 8x - 1) = 7(x - 1)  \\ 5x + 7 + 16x + 2 = 7x - 7 \\ collecting \:  like \:  \: terms \:  \\ 5x + 16x - 7x =  - 7 - 2 - 7 \\ 14x =  - 16 \\ divide \: both \: side \: by \: 14 \\  \frac{14x}{14}  =  \frac{ - 16}{14}  \\ x =   - \frac{ 8}{7}

A brand new filled jar of salsa is 11 cm tall and a has a radius of 6 cm. Kelly eats some of the salsa and the salsa in the jar
Sonbull [250]

Before we begin please note that a jar is always cylindrical in shape if not mentioned otherwise. Thus, we will take a cylindrical jar in this case.

Since Kelly eats some of the salsa and the salsa in the jar is now 6 cm high, we know that Kelly ate the amount of Salsa whose volume is missing from the jar.

To find the missing volume on the Salsa jar all that we need to do is to find the height of the missing volume which is given to us as h= 6 cm. We already know that the radius of the jar, r=6 cm. Thus, the amount of Salsa Kelly has eaten is:

V=\pi(6)^2\times 6\approx678.6\approx679 cm^3

Thus, the third option is the correct answer

One angle of an isosceles triangle measures 70°. Which other angles could be in that isosceles triangle?
Mrrafil [7]

Answer:

Step-by-step explanation:

The total of all 3 angles in every triangle equals 180 degrees.  An isosceles triangle has two side lengths equal and two angle degrees equal.  

So you either have two angles with each having 70 degrees and the third angle is 40 degrees,  

70 + 70 + 40=180

OR

One angle of 70 degrees and two angles that are 55 degrees each.  

70 + 55 +55 =180
