Answer 1

Answer:

Answer:

35.1

Step-by-step explanation:

There's a formula that i've linked as an image

Basically, substitute all 3 sides and the length into that formula, chuck it into the calculator and viola.

Or... we can use pythagoras' theorem and get the height of the triangle Height = $3^(2)$ - $1.5^(2)$ = 2.6

Area of triangle = (3 * 2.6) / 2 = 3.9

Volume = 3.9 * 9

Volume of prism = 35.1

Thomas has $6.35 in dimes and quarters. The number of dimes is three more than three times the number of quarters. If q represents the number of quarters, then which of the following expressions represents the number of dimes that Thomas has? 3d + 3 3q + 3 6.35 - q 10(3q + 3)

Answers

3q+3 because if the dimes is 3x as many as the quarter and plus 3 then you would multiply the quarters by 3 then add 3 and that would give you the number of dimes

Cannon took out a mortgage for $85,290 on his new house. If the interest rate is 8.5 percent and the loan is for 25 years, how much will he pay monthly if he must pay $8.05 per $1000?What steps should I take here to get my answer?

Answers

85 290 dollars is his loan which is for 25 years with 8.5 percent fixed rate.
=> 85 290 * 0.85 = 7249.65 dollars for the interest
=> 85 290 + 7249.65 = 92 539.65 dollars
=> 92539.65 / 25 years = 3701.59 dollars yearly
=> 3701.586 / 12 = 308.47 dollars monthly.

Step-by-step explanation:

the sum of Kris and Victor's ages is 27 years. in 3 years, victor will be twice as old as Kris will be. what are their present ages?

Answers

let k=kris and victor =v
k+v=27
in 3 years, victor will be twice as old as kris will be.so
v+3=2(k+3)
v=2k+6-3
v=2k+3
so (2k+3)+k=27
3k=24
k=8 27-8=19
kris is 8 years now. victor is 19 years old.

LET KRIS'S AGE BE X YEARS AND VICTOR'S AGE BE Y YEARS
GIVEN, X + Y = 27 ------------EQ 1
IN THREE YEARS,
KRIS WILL BE X+3 YEARS AND VICTOR WILL BE Y+3 YEARS
GIVEN , Y+3 = 2(X +3 )
Y+3 = 2X+ 6
Y - 2X =6-3
Y - 2X =3 ------------EQ 2
FROM EQ 1 WE GET,
X =27 -Y
SUBSTITUTING THE VALUE OF X IN EQ 2 ,WE GET
Y - 2(27 -Y) =3
Y - 54 +2Y =3
3Y-54 =3
3Y =57
Y=57/3 =19
PUTTING THE VALUE OF Y IN EQ 1
X +19 =27
X =27-19=8
THEREFORE, KRIS IS 8 YEARS OLD AND VICTOR IS19 YEARS OLD
