Answer:

Sinθ = 24/25

Step-by-step explanation:

Sinθ = Opposite/Hypotenuse

Solve for the opposite side using the Pythagorean Theorem.

$a^2+b^2=c^2\\7^2+b^2=25^2\\49+b^2=625\\b^2=576\\b=24$

Therefore, Sinθ = 24/25.

On Monday, Torrance practiced the violin for 4/10 of an hour. On Tuesday, he practiced for 1 6/8 of an hour. How much time did h

Yuri [45]

Answer: $2\frac{3}{20}$

<u>Step-by-step explanation:</u>

First, convert mixed numbers into improper fractions and simplify all fractions

$\frac{4}{10}$ ÷ $\frac{2}{2}$ = $\frac{2}{5}$

$1\frac{6}{8}$ = $\frac{8(1) + 6}{8}$ = $\frac{14}{8}$ ÷ $\frac{2}{2}$ = $\frac{7}{4}$

Next, find their sum. Remember to find the LCD and convert the fractions so they have like denominators.

Monday + Tuesday = Total

$\frac{2}{5}$ + $\frac{7}{4}$ = Total <em>the LCD of 5 and 4 is 20</em>

$(\frac{4}{4})\frac{2}{5}$ + $(\frac{5}{5})\frac{7}{4}$ = Total

$\frac{8}{20}$ + $\frac{35}{20}$ = Total

$\frac{43}{20}$ = Total

Then, convert the improper fraction into a mixed number

$\frac{43}{20}$ = $2\frac{3}{20}$

ABCD is a parallelogram. Find the values of x and y. Solve for the value of z, if z=x−y.

slava [35]

Answer:

Step-by-step explanation:

Parallel and opposite sides of a parallelogram are equal. Hence, we can say:

x + 30 = 2x - 10

and

2y-10 = y +10

Solving first one, we get:

x + 30 = 2x - 10

30+10 = x

x = 40

Also

2y - 10 = y + 10

y = 10 + 10

y = 20

Now, z = x - y, so

z = 40 - 20 = 20

Answer C is right.
