In a circle, a 270degrees sector has area 75pi inches squared. What is the radius of the circle?

wariber [46]

A 270 degree of sector = 0.75 of its area
area = π r²
so,
      0.75 π r² = 75 π

       r² = (75 π)/( 0.75 π) = 100

       r = +√100 = 10
so
    The radius of the circle is 10 in

What does 6 cubed times 16+24 divided by 4 equal when simplified

Allisa [31]

This is tricky, as your sentence can be interpreted in multiple ways. The sentence translates into one of the following expressions:

$\frac{(6^2 \cdot 16 + 24)}4 = 150$

or:

$6^2 \cdot 16 + \frac{24}4 = 582$

or

$6^2 \cdot (16 + \frac{24}4) = 792$

or

$\frac{6^2 \cdot (16 + 24)}4 = 360$

if z (3,-1) is the midpoint of line segment of coordinate x (5,2) and y (a,b) then find the value of a and b. I need it fast if

Gwar [14]

Answer:

the coordinates of y are (1,-4)

Step-by-step explanation:

by using midpoint formula

z(x,y)=( $\frac{x1+x2}{2}$ , $\frac{y1+y2}{2}$ )

putting the values of coordinates

(3,-1)= $\frac{5+a}{2}$ , $\frac{2+b}{2}$

separating the coordinates

3= $\frac{5+a}{2}$ and -1= $\frac{2+b}{2}$

3×2=5+a and -1×2=2+b

6=5+a and -2=2+b

6-5=a and -2-2=b

1=a and -4=b

so the actual coordinates of y are (1,-4)

i hope it will help you

Peter has found a job in a computer store. A shown below he has two options for how he will be paid. The commission he makes for

vovangra [49]

Missing part of the question:

For option A) he will have fixed salary of $600 per week with no commission. What would his weekly sales need to be for him to make more than he would for Option A. (Picture is attached)

Answer:

More than $4,375

Step-by-step explanation:

If he goes for Option B he will have to earn more than $350 (600-250) as a commission (8% of total sale) along with his salary of $250 to make more than he would for option A i.e. $600.

<u>We have to find the amount whose 8% is $350:</u>

$\frac{8}{100}*x = 350 \\x=\frac{350*100}{8} \\x=4,375$

So, if his weekly sale should be more than $4375 to make more than he would have for Option A.
