We have an equation: 13/?= 26/100
Cross multiply:
26*?= 13*100
⇒ ?= 13*100/26= 50
13 is 26% of 50~
Answer:
a) 47.7%
b) 87.2%
Step-by-step explanation:
Find the ratio of interest, and convert it to a percentage.
<h3>a) </h3>
(messy right-handed writers)/(right-handed writers)
= 31/65 = 31/65 × 100% ≈ 47.7%
__
<h3>b) </h3>
(neat right-handed writers)/(neat writers)
= 34/39 = 34/39 × 100% ≈ 87.2%
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>
