Answer:

Answer: <u> </u><u> </u><u>d</u><u> </u><u>is</u><u> </u><u>2</u><u>0</u><u> </u>

Step-by-step explanation:

{ \rm{p \:  \alpha \: d}} \\  \\ { \rm{p = kd}}

k is a constant of proportionality

• When p = 3, d = 5.

{ \rm{3 = (k \times 5)}} \\  \\ { \rm{k =  \frac{3}{5} }}

• Therefore, equation becomes;

{ \rm{p =  \frac{3}{5} d}}

• Let's find d when p is 12;

{ \rm{12 =  \frac{3}{5}d }} \\  \\ { \rm{d =  \frac{12 \times 5}{3} }} \\  \\ { \underline{ \underline{ \rm{ \:  \: d = 20 \:  \: }}}}

Answer: 230. 34 times five is 170. Then you are left with 170 + 3 + 43 + 4 + 3 +4 + 3. You can combine the 3's and you get 9. You are left with 179 + 4 +4 + 43 You combine the 4's and you get 187. 187 + 43 = 230.

Jaime makes the following claim.
Sphinxa [80]

Jaime is incorrect, the angle does not depend on the radius of the circles.

<h3>Is Jaime correct?</h3>

Remember that an angle that defines an arc on a circle, does not depend on the radius of the circle.

So, if we have an angle with a measure of π/3 radians in a circle with a radius of 3 inches and an angle with a measure of π/3 radians in a circle with a radius of 6 inches, these two angles are exactly the same thing.

The radius of the circle only has an impact on the length of the arc defined by the angle.

So Jaime is clearly incorrect.

What is the solution to 4 (m-3) + 19 = 8 (2m + 3) + 7?
Flauer [41]

Answer:

x=-2

Step-by-step explanation:

Let m=x

4(x-3)+19=8(2x+3)+7\\

Expand the parentheses:

4x-12+19=16x+24+7\\4x+7=16x+31\\-31+7=16x-4x\\-24=12x\\x=-2
