Answer:
Step-by-step explanation:
we know that If two angles are complementary, then their sum is equal to 90 degrees
Letx -----> the measure of an angle
y-----> the measure of he other angle
we know thatx+y=90 -----> y=90
-x -----> equation
Ax=y+54 ----> equation
Bsubstitute equation B in equation A and solve for yy=90-(y+54)
y=90-y-542y=36y=18°
Find the value of xx=y+54 -----> x=18+54=72°
thereforeThe measure of the angles are 72 degrees and 18 degrees

<u><em>Answer:</em></u>
<h2>the regular price of the item is $80.</h2>
<u><em>Step-by-step explanation:</em></u>
Let p represent the regular price of the item.
p - p×(40/100) = 48 ⇌ p×(1 - 40/100) = 48 ⇌ p×(100/100 - 40/100) = 48
⇌ p×(60/100) = 48 ⇌ p = (480×100)/60 = 48 000/60 = 80.

Answer:
Step-by-step explanation:
<u>We know that:</u>
- r = 4.51 inches
- h = 10 inches
- Volume formula = πr²h
<u>Solution:</u>
- π x r² x h = Volume
- => 22/7 x 4.5² x 10 = Volume
- => 22/7 x 4.5 x 4.5 x 10 = Volume
- => 22/7 x 20.25 x 10 = Volume
- => 22/7 x 202.5 = Volume
- => 636 inches (Rounded)
Hence, Option B is correct.
We know that we're starting from a certain number m and, after subtracting 23, we're left with -50.
So, you can invent any word problem involving some initial amount, a subtraction of 23, and a result of -50. For example:
"Mary spent $23, and her bank account reads $-50. How much money did Mary have in the first place?".
or
"After the temperature dropped 23 degrees, it was -50 degrees outside. What was the temperature before the drop?"
