Answer:

BCG =65

Step-by-step explanation:

DCG + GCB = DCB

We know BCG = 31x+3 and GCD = 12x+2  and BCD = 91

Substituting these in

12x+2 + 31x+3 = 91

Combine like terms

43x +5 = 91

Subtract 5 from each side

43x+5-5 = 91-5

43x = 86

Divide by 43

43x/43= 86/43

x=2

BCG = 31x+3

        =31(2)+3

         =62+3

           =65

m∠BCD = m∠BCG + m∠GCD

We have m∠BCG = 31x + 3, m∠GCD = 12x + 2 and m∠BCD = 91°. Substitute:

91 = (31x + 3) + (12x + 2)

91 = (31x + 12x) + (3 + 2)

91 = 43x + 5       <em>subtract 5 from both sides</em>

86 = 43x       <em>divide both sides by 43</em>

2 = x

m∠BCG = 31x + 3 → m∠BCG = 31(2) + 3 = 62 + 3 = 65

<h3>Answer: m∠BCG = 65°</h3>

There are two spheres of different sizes. The large sphere has a radius 3 times the size of the small sphere. How many times lar
Vikentia [17]

Answer:

The answer to your question is the letter B. 27

Step-by-step explanation:

Data

The Radius of large sphere = 3 times the size of the radius small sphere.

The Ratio of Volume = ?

Formula

Volume of a sphere = 4/3 πr³

Process

1.- Calculate the volume of the large sphere

                   Vl = 4/3 π(3r)³

2.- Calculate the volume of the small sphere

                   Vs = 4/3 πr³

3.- Calculate the ratio

                   Vl / Vs = [4/3π(3r³)] / [4/3 πr³]

- Simplification

                   Vl / Vs = 3³r³ / r³

                   Vl / Vs = 27

Jose worked 2.5 hours more than William. together they worked a total of 22 hours. William worked h hours
nataly862011 [7]

I believe that the answer you're looking for is B. h+(h+2.5)=22.

h+(h+2.5)=22

h+h+2.5=22

Combine like terms.

2h+2.5=22

Subtract 2.5 from both sides.

2h=19.5

Divide both sides by 2.

h=9.75

Now let's check the work by plugging 9.75 into the equation.

9.75+(9.75+2.5)=22

9.75+9.75+2.5=22

22=22

So we now see that the answer choice <u>B.</u> Is correct! And William worked 9.75 hours. I hope that you found this helpful!
