Anais bought 4 1/2 yards of ribbon. She had 3 feet 8 inches of ribbon left after trimming some curtains. How many inches of ribbon did anais use to trim the curtains
Answers
Answer:
First convert all numbers into inches since that is the answer being solved for.
1 yard =36 inches
4.5 x 36 = 1,620 inches
1 foot = 12 inches
3 x 12 = 36 inches
36 + 8 = 44 inches
Now take 1,620 inches (starting ribbon measure) and subtract 44 inches (what was left over) to get the inches used to trim curtains.
1,620 inches - 44inches =
1,576 inches were used to trim the curtains.

Find the measure of angle b
Answers
Answer:
26˚
Step-by-step explanation:
Since there is already two angles (The square in the corner shows that the angle is 90˚)
So subtract 90˚ with 64˚ which is 26˚
Answer:
this whole angle is equal to 90°
so the value of angle b = 90°-64°
so the value of b= 26.

b. 84%
2. 175
3. $867.18
Step-by-step explanation:
1. a.2.32-0.36=1.96
1.96/0.36=5.44

y is 125% of x
y=1.25x
x=140
y=1.25*140
y=175

Rearrange this formula to make x the subject.
y = 3x2 - 2
Answers
Answer:
The subject 'x' in terms of 'y'
[tex]x = \sqrt{\frac{y+2}{3} }[/tex]
Step-by-step explanation:
Explanation:-
Given subject in terms of 'x'
y = 3 x² - 2
Adding '2' on both sides, we get
y + 2 = 3 x² - 2 +2
y+2 = 3 x²
Dividing '3' on both sides, we get
[tex]x^{2} = \frac{y+2}{3}[/tex]
[tex]x = \sqrt{\frac{y+2}{3} }[/tex]
