Its easy there are 6 sides that are equal so, 6 x 6 is 36 and thats the awnser, 36 your welcome!!!!! Hope this helps
Answer:
<h2><em>
y = 8, ST = 31 and RT = 81</em></h2>
Step-by-step explanation:
Given RS = 6y+2, ST=3y +7, and RT=13y-23, the vector formula is true for the equations given; RS+ST = RT
Om substuting the expression into the formula;
6y+2+3y +7 = 13y - 23
collect the like terms
6y+3y-13y+2+7+23 = 0
-4y+32 = 0
Subtract 32 from both sides
-4y+32-32 = 0-32
-4y = -32
y = -32/-4
y = 8
Since ST = 3y+7. we will substitute y = 8 into the exprrssion to get ST
ST = 3(8)+7
ST = 24+7
ST = 31
Similarly,
RT = 13y-23
RT = 13(8)-23
RT = 104-23
RT = 81
<em>Hence y = 8, ST = 31 and RT = 81</em>
Answer is 5100
510(3) = 1530
510(7)=3570
Add them together
4πm³/8
Step-by-step explanation:
The surface area of a sphere is calculated using the formulae;
= 4*π*r3
Given the diameter m, we can find the radius by dividing it into half;
= m/2
Then we replace r with m/2 in the surface areas formulae;
= 4*π* (m/2)³
= 4πm³/8

Answer:
y = 2.50x
Step-by-step explanation:
Grapes cost $2.50 per pound
which equation represents y, the total cost of grapes at x pounds?
To get the value of x pounds
1 pound of grape cost $2.50
x pounds of grapes cost y
to get y
cross multiply
y x 1= x ($2.50)
y = 2.50x
