  • XW=12

\\ \sf\longmapsto tan60=\dfrac{WZ}{XW}

\\ \sf\longmapsto \sqrt{3}=\dfrac{WZ}{12}

\\ \sf\longmapsto WZ=12√3

\\ \sf\longmapsto WZ=20.78

Now

\\ \sf\longmapsto XZ^2=20.78^2+12^2

\\ \sf\longmapsto XZ^2=431.8+144

\\ \sf\longmapsto XZ^2=575.8

\\ \sf\longmapsto XZ\approx 24

Now

\\ \sf\longmapsto cos\Theta=\dfrac{XW}{XZ}

\\ \sf\longmapsto cos\Theta=\dfrac{12}{24}

\\ \sf\longmapsto cos\Theta=\dfrac{1}{2}

Option C

N = nickels and q = quarters

0.05n + 0.25q = 1.90
n = 2q + 3

0.05(2q + 3) + 0.25q = 1.90
0.10q + 0.15 + 0.25q = 1.90
0.10q + 0.25q = 1.90 - 0.15
0.35q = 1.75
q = 1.75/0.35
q = 5 ......there are 5 quarters

n = 2q + 3
n = 2(5) + 3
n = 10 + 3
n = 13 <=== there are 13 nickels

Carlos read 144 pages in 3 hours. His little sister read 24 pages in 1 hour. carlos's average reading rate is what percent of hi
ehidna [41]
Hello! So Carlos' sister reads an average of 24 pages in 1 hour. He reads 144 pages in 3 hours. To find the unit rate Carlos reads, let's do some division. 144/3 is 48. Carlos reads an average of 48 pages in 1 hour. If you use mental math, 48 is double the amount of 24. 200% is just simply 2. 24 * 2 is 48. D is the only one that shows an answer that even fits for this scenario. Carlos' average reading rate is 200% of his sister's. The answer is D: 200%.
