Hello! answer: the area is 528

Step-by-step explanation:

When finding area you should split the shapes up so forst im going to do the two sides that are the same those are just simply 10 x 12 = 120 10 x 12 = 120 So i add those up and get 240 I'll add this with the other sides later now Im going to do the front face thats a square that is 16 x 12 = 192 Now I'm just going to do the triangles that is 16 x 6 = 96 then I divide by 2 cause thats the formula for finding triangle area now I have 48 but since there are two of those triangles ill just do 48 x 2 = 96 now that I have All the faces im going to add them all up so... 240+ 192 + 96 = 528 Hope this explains well!

2 times x, minus by x and 2

kati45 [8]

Answer:The term X is a variable that takes the place of any number. ... If X stands for the number 13 then 2 times 13 is equal to 13 plus 13 which gives 26 when added. Similarly 2 multiplied by X results to X plus X which means a number added to itself since multiplication is a repeated addition. So 2X = 2 * X = X + X = 2X.

Step-by-step explanation:hope that helps

Tju [1.3M]

Answer:

0.98 also 98%

Step-by-step explanation:

In this question we have the Lower limit to be 0.16

We have the Upper limit to be 0.24

Such that (0.16+0.24)/2 = 0.40/2 = 0.20

Standard deviation= √(0.2x0.8/545) this gives 0.017134

Next we get margin of error

Margin of error = 0.24-0.20 = 0.04

Z multiplied by sd =0.04

Such that

Z = 0.04/0.017134 =2.33

On this z score, the Corresponding level of confidence is 0.98

Which is 98%

In triangle VWX, VW = 4.5 inches, WX = 5.9 inches, Measure of angle W = 28 degrees, and Measure of angle X = 47 degrees. If Tria

lesya692 [45]

Answer:

There are two statements that are true:

B. QR = 5.9 cm

D. Measure of angle R = 47 degrees

Step-by-step explanation:

1. Let's recall that if ΔVWX ≅ ΔPQR, then:

VW ≅ PQ

WX ≅ QR

PR ≅ VX

therefore, QR is 5.9 cm and not 4.5 cm

2. Let's recall that if ΔVWX ≅ ΔPQR, then:

∠V ≅ ∠P

∠W ≅ ∠Q

∠X ≅ ∠R

therefore, measure of ∠R is 47° and not 28°

There are two statements that are true:

B. QR = 5.9 cm

D. Measure of angle R = 47 degrees
