Examine the diagram of circle V, where two chords, JK and LM, are equidistant from the center. If JK=4x+37, and LM=5(x+5), what

77julia77 [94]

Answer:

x=12

Step-by-step explanation:

we know that

If the two chords are equidistant from the center of the circle, then the chords must be congruent.

JK=LM

substitute the given values

$4x+37=5(x+5)$

solve for x

$5x-4x=37-25\\x=12$

The rectangular prism is made of 8 cubes and has and edge length of 1/2 in, what is the volume

sashaice [31]

Hello!

To find the volume of the prism you first have to find the volume of a cube

To do this you use the equation

$V = a^{3}$

V is volume
a is side length

Put in the values you know

$V = \frac{1}{2}^{3}$

Solve

V = 0.125

Now to find the volume of the prism you multiply the volume of one cube by the amount of cubes in the prism

0.125 * 8 = 1

The answer is 1 cubic inch

Hope this helps!

11. WRITING EQUATIONS Write a rule for the arithmetic sequence with the given description.

a. The first term is −3 and each term is 6 less than the previous term.

b. The first term is 7 and each term is 5 more than the previous term.

12. WRITING Compare the terms of an arithmetic sequence when d > 0 to when d < 0.

In Exercises 13–20, write a rule for the nth term of the sequence. Then find a20. (See Example 2.)
