Find the measurement of both complementary angles, if:

aniked [119]

We are given one angle is 3 times less than other.

Let us assume one angle measure is x degrees and another is 4x.

Because x is 3x less than 4x. ( We can check 4x-x= 3x)

Sum of complementary angles is 90 degrees.

So, we can setup an equation

First angle measure + first angle = 90 degrees.

x+4x = 90.

Adding x and 4x, we get 5x.

So, 5x = 90.

Dividing both sides by 5, we get

5x/5 = 90.

x= 18.

So, one angle is of 18 degrees.

Another angle = 4x = 4 times 18 = 72 degrees.

So, required angles are of 18 degree and 72 degree.

A rectangular picture frame has side lengths of 12 in by 9.5 in what is the length of the diagonal of the picture

OleMash [197]

Answer:

Length of diagonal of picture = 15.30 inches

Step-by-step explanation:

Given that:

Side lengths of picture frame = 12 inches by 9.5 inches

As the picture is rectangular, the diagonal will form hypotenuse of right angled triangle.

Using Pythagorean theorem;

a²+b²=c²

Putting the values in the theorem

$(12)^2 + (9.5)^2 = c^2 \\144+90.25=c^2\\c^2 = 234.25$

Taking square root on both sides

$\sqrt{c^2}=\sqrt{234.25}\\c=15.30$

Hence,

Length of diagonal of picture = 15.30 inches

A store has a bargain bin filled with red (R), blue (B), pink (P), and yellow (Y) shirts in sizes small (S) and large (L). Which

olasank [31]

Option D:

Possible outcomes when randomly pulling one shirt from the bin are

RS, RL, BS, BL, PS, PL, YS, YL

Solution:

Color of shirts are:

Red (R), Blue(B), Pink(P), Yellow(Y).

Size of shirts are:

Small(S), Large(L)

This means that each color of shirts have both in small and large size.

Shirts in bargain bin are:

Red in Small (RS), Red in Large (RL)

Blue in Small (BS), Blue in Large (BL)

Pink in Small (PS), Pink in Large (PL)

Yellow in Small (YS), Yellow in Large (YL)

Possible outcomes when randomly pulling one shirt are:

RS, RL, BS, BL, PS, PL, YS, YL

Hence Option D is the correct answer.
