This is a rectangular cake, and there are 3 measurements, meaning that you are evidently finding volume.

Let's go back, first off, the formula for volume is...

V = L x W x H (Length, Width, Height)
Your measurements are 9 in, 13 in, 2 in.

All you need to do is follow the formula and multiply them.

9 x 2 = 18
18 x 13 = 234 in^{2}

Your answer is C: 234 in^{2}

Hope this helps!

The first three terms of an arithmetic sequence are 3k-1, 4k+1, 6k-2. What is the value of k?​
yawa3891 [41]

Answer:

k = 5

Step-by-step explanation:

First three terms of an AP are 3k-1, 4k+1, 6k-2.

First term is 3k-1

For an AP,

a₂-a₁=a₃-a₂

4k+1-(3k-1)=6k-2-(4k+1)

4k+1-3k+1=6k-2-4k-1

k+2=2k-3

Separating like terms,

k-2k=-3-2

-k=-5

k = 5

So, the value of k is 5.

If PQR = STU, find the measure of each part.
alina1380 [7]

The answer is below

Step-by-step explanation:

Two triangles are said to be congruent if for the two triangles all the three sides are equal and all the three angles are equal to each other.

Given that ΔPQR is congruent to ΔSTU, hence all corresponding sides and corresponding angles are equal to each other.

∠P = ∠S = 59°

∠S + ∠T + ∠U = 180° (sum of angles in a triangle)

59 + 75 + ∠U = 180°

134 + ∠U = 180°

∠U = 46°

∠U = ∠R = 46°

∠Q = ∠T = 75°

Also, for the sides:

ST = PQ = 7 m

SU = PR = 8 m
