Zahara constructs 5 mirror frames in 30 minutes. At that rate, how many mirror frames can Zahara make in 9 hours
NARA [144]

Answer:

If 5 mirrors=30 mins

then x=9 hrs

therefore 30÷60 to covert it to hours is equal to 0.5hr

5×9hrs÷0.5hr=90

Evaluate ln 7<br><br> A.) 0.51<br><br> B.) 1.95<br><br> C.) 0.85<br><br> D.) 1.61
Semmy [17]
We may log in directly in our scientific calculator the given value ln 7 and get an answer of 1.9459. On the other hand, we can rewrite the expression as,
                             log to the base e or 7 = x
which can be written as,
                               e^x = 7
The value of x from this is still equal to 1.9459.

Hello! Please help thanks
kogti [31]

Answer:

A. \frac{5}{13}

Step-by-step explanation:

Hi there!

We are given right triangle PQR, with PR=5, RQ=12, and PQ=13

We want to find the value of sin(Q)

Let's first recall that sine is \frac{opposite}{hypotenuse}

In reference to angle Q, PR is the opposite side, RQ is the adjacent side, and PQ is the hypotenuse

So that means that sin(Q) would be \frac{PR}{PQ}

Substituting the values of PR and PQ gives sin(Q) as \frac{5}{13}, which is A

Hope this helps!
