Answer:
The measure of angle ∠ b is 68°.
Step-by-step explanation:
There are two angles ∠ a and ∠ b which are complementary.
Therefore, from the definition of complementary angles, we have
∠ a + ∠ b = 90°
Now, if the angle ∠ a is measured to be 22°, then
22° + ∠ b = 90°
⇒ ∠ b = 90° - 22°
⇒ ∠ b = 68°
Therefore, the measure of angle ∠ b is 68°. (Answer)
Hello there!
Speed has the following formula:
S =
, or
Speed is equivalent to
Distance divided by Time.Let's check out our problems to solve for the speed.
16.)
We have 770 miles, which is a measure of distance.
We have 120 minutes, which is a measure of time.
Let's substitute our variables with these numbers.
S =
Simplify.
S = ~6.41 Mi/min
17.)
We have 2.5 mi, which is our measurement of distance.
We have 0.5 h, which is our measurement of time.
S =
Simplify.
S = 5 Mph (When you divide by 0.5 you are multiplying the numerator by 2).
18.)
We have 244 km, our distance.
We have 2.5 h, our time.
S =
Simplify.
S = 97.6 km/h
I hope this helps!
x = 4 and y = 9 and z = 7
x(y + z - 32) = 4 · (9 + 7 - 32) =
= 4 · (16 - 32) = 4 · (-16) = <u>-</u><u>6</u><u>4</u>
Answer:
10x + 7 = 85
8 packs
Step-by-step explanation:
Let's let packs = x
10 shirts in a pack = 10x
So we know that since he has 7 packs already, that can be our y-intercept in this equation
This will leave us with 10x + 7
And since we can't have a partial amount of packs, we round up to 8 total packs
Hope this helps
