Answer:
Blues Paints = 2.45 pints
Step-by-step explanation:
Let's generate an expression that would relate all the variables given:
Total pints of paints used:
9.8 = white + blue
Pints of white paint used:
= 3/4 of 9.8
=0.75 * 9.8
=7.35
Number of pint of BLUE PAINTS used:
9.8 = White Paints + Blue Paints
9.8 = 7.35 + Blue Paints
Blue Paints = 9.8 - 7.35
Blues Paints = 2.45
Kate used 2.45 pints Blues Paints for her bedroom
Answer: A 28.50 sq. u
Step-by-step explanation:
In the given figure , radius of the circle : r= 10 u
Central angle made by Arc ED: 
= 90° ( right angle )
Now , the area of the segment is given by :-
Area of segment = Area of sector (ECD) - Area of triangle(ECD) (i)
Formula : Area of right triangle = 0.5 x Base x Height
Area of sector = 
Using above formulas in (i) and substituting corresponding values , we get
Area of segment =
Hence, the correct answer is A 28.50 sq. u
Answer:
It will take Naomi 22 hours
Step-by-step explanation:
If they work together Mark, Naomi, and Yvonne take 11 hours, which means
three people represent 3* 11 = 33 man* hours
If they work alone Yvonne will take 5 man hours, and Mark will take 6* man hours.
Now we know that together they take 33 man hours therefore we have
5+ 6+ N = 33
Where N is Naomi's man* hours. We solve for N and get:
N = 33 - 11 = 22
N = 22
Naomi will take 22 hours to finish the job if she worked alone.
Answer:
30. $<u>25.42</u>
31. $<u>21.48 </u>
32. $<u>23.06</u>
Step-by-step explanation:
30. 8.54+7.50+9.38 = 25.42
31. 6.99+5.99+8.50 = 21.48
32. 8.50+5.33+9.23 = 23.06
