Answer:
The answered 5 math questions, and 5 science questions.
5 * 3 = 15
5 * 10 = 50
15 + 50 = 65
Step-by-step explanation:
Answer:
-4 *-4 *-4
= 16*-4
= ANWSER
-9*-9
=81
Step-by-step explanation:
Let's read through this and make an equation:
? ("number")
? / -7 ("quotient of a number and -7")
(? / -7) - 2 ("decreased by 2")
<span>(? / -7) - 2 = 10 ("is 10")
</span>
Now we can solve:
<span>(? / -7) - 2 = 10
</span><span>? / -7 = 12
</span>? = -84
The number is -84
Answer:
21.4 degrees =x
Step-by-step explanation:
We can use the law of sines to solve this problem
sin A Sin B
------------ = ----------
a b
where A is the angle and a is the opposite side
sin 42 Sin x
------------ = ----------
22 12
Using cross products
12 sin 42 = 22 sin x
Divide by 22
12/22 sin 42 = 22/22 sin x
12/22 sin 42 = sin x
Take the arcsin of each side
arcsin (12/22 sin 42) = arcsin( sin x)
arcsin (12/22 sin 42) = x
21.40637223=x
Rounding to the nearest tenth
21.4 degrees =x
