Answer:

  4 : 9

Step-by-step explanation:

The requested ratio is ...

  tile length : board length = (2/3 ft) : (1/2 yd) = (8 in) : (18 in)

  = 8 : 18 = 4 : 9

_____

To make a unitless ratio, both parts must have the same units. Here, we chose to express the lengths in inches. We could have used feet or yards as well. (2/3 ft)×(1 yard)/(3 ft) = 2/9 yd or (1/2 yd)(3 ft/yd) = 3/2 ft. You get the same ratio with any of these:

  (2/9 yd) : (1/2 yd) = (4 yd) : (9 yd) = 4 : 9 . . . . . multiply by 18

  (2/3 ft) : (3/2 ft) = (4 ft) : (9 ft) = 4 : 9 . . . . . multiply by 6

2) Suppose that circles A and B have a central angle measuring 40°. Additionally, circle A has a radius of 5 2 ft and the radius
sleet_krkn [62]

Let 

rA--------> radius of the circle A

rB-------> radius of the circle B

SA------> the area of the sector for circle A

SB------> the area of the sector for circle B 

 

we have that

rA=5/2 ft

rB=9/2 ft

rA/rB=5/9-----------> rB/rA=9/5

SA=(25/36)π ft²

 

we know that

 

if Both circle A and circle B have a central angle , the square of the ratio of the radius of circle A to the radius of circle B is equals to the ratio of the area of the sector for circle A to the area of the sector for circle B

 

(rA/rB) ^2=SA/SB-----> SB=SA*(rB/rA) ^2----> SB=(9/5) ^2*(25/36)π--->

<span>SB----------- > (81/25)*(25/36)------ > 81/36------ >  9/4π ft²</span>

 

the answer is

<span>the measure of the sector for circle B is (9/4)π ft²</span>

What is 5r^2 = 80<br><br> It says solve each equation with the quadratic formula.
katovenus [111]
5r^2 = 80 \ \ /:5\\ \\r^2=\frac{80}{5}\\ \\r^2=16\\ \\r^2-16=0\\ \\ r^2 - 4^2 =0 \\ \\(r-4)(r+4)=0

r-4=0 \ \ \vee \ \ r+4 =0 \\ \\r=4 \ \ \vee \ \ r = -4 \\ \\ \\ a^2-b^2 = (a- b)(a+b)

The radius of a cylindrical construction pipe is 1.5ft. If the pipe is 12 ft long, what is its volume?
yulyashka [42]

Answer:

approx 84.82 cubic. ft

Step-by-step explanation:

volume of cylinder =

volume = \pi {r}^{2} h

= 3.14 * (1.5)(1.5) * (12)

= 3.14 * 2.25 * 12

= 7.065 * 12

= approx 84.8 cubic. ft
