Answer:
Scientific notation is a way of writing long numbers, often with a lot of zeros, in a shorter and easier to read format.
Step-by-step explanation:
As an example I will use 360
first move the decimal so the number is larger than one but less than ten
So the number will be 3.60
to make it equal to 360 it would be 3.6 x 10^2 multiplying 3.6 by 10 to the power of 2 will make it 360. for a more in depth and probably better explination I would check khan academy.
Answer:
x = 16
Step-by-step explanation:
Verticle angles are always congruent, so:
(8x + 15) = 143
Now, we can solve to isolate x:
8x + 15 - 15 = 143 - 15 (subtract 15 from both sides)
8x/8 = 128/8 (divide both sides by 8)
x = 16
You can always plug in the value of x to the original equation to check your answer:
8(16) + 15 = 143
Answer:
<u>There are two statements that are true:</u>
<u>B. QR = 5.9 cm
</u>
<u>D. Measure of angle R = 47 degrees</u>
Step-by-step explanation:
1. Let's recall that if ΔVWX ≅ ΔPQR, then:
VW ≅ PQ
WX ≅ QR
PR ≅ VX
<u>therefore, QR is 5.9 cm and not 4.5 cm</u>
2. Let's recall that if ΔVWX ≅ ΔPQR, then:
∠V ≅ ∠P
∠W ≅ ∠Q
∠X ≅ ∠R
<u>therefore, measure of ∠R is 47° and not 28°</u>
<u>There are two statements that are true:</u>
<u>B. QR = 5.9 cm
</u>
<u>D. Measure of angle R = 47 degrees</u>
