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>
Graph C represents x = -2
Answer:
Step-by-step explanation:
45% = 45/100 = 0.45
- 0.45x = 18
- x = 18/0.45
- x = 40
100% is $40
Answer: 125lb < M < 155 lb
Step-by-step explanation:
The mean mass is 140 lb, and the deviation must be less than 15 pounds (exactly 15 is not accepted).
Then (140lb + 15lb) is not alowed, and (140lb - 15lb) is not alowed.
Then we can define M = mass.
We have the two equations:
M < 140lb + 15lb
M < 155lb
And
M > (140lb - 15lb)
M > 125lb
If we write these two relations togheter, we get:
125lb < M < 155 lb
