Answer:
12^2 is 144 and 10^2 is 100 :)
Step-by-step explanation:
12 * 12 = 144
10 * 10 = 100
The sum of the 12th square number and the 10th square number is 244. This problem is based on the principle of addition.
The principle of addition states that when two numbers are added together, their sum is a unique number which is not necessarily be divisible by either the numbers or their factors. The addition is inverse operation of the subtraction.
The square of 12th number is 12² = 12 × 12 = 144.
The square of 10th number is 10² = 10 × 10 = 100.
The sum of both numbers = 144 + 100 = 244.
Hence, the answer to the given problem is 244.

Explain the steps you could use to solve 3y + 6 = 30 to find y
Answer:
3y+6-6=30-6 (subtract 6 from both sides)
3y=24 (simplfy by subtracting those numbers)
3y/3 = 24/3 (divide both sides of the equation)
y=8 (simplfy by divding with those numbers)

Al and Tom are painting a shed. Working alone, Al can paint the shed in 2 hrs. Together they can paint the shed in 1.5 hours. How long would it take Tom to paint the shed on his own?
Answer:
6 hours.
Step-by-step explanation:
The formula sort of has to be invented.
Al
rate = 1 shed / 2 hours
Tom
rate = 1 shed / x hours.
Together.
rate = 1 shed / 1.5 hours.
Equation
1 shed / 2 hours + 1 shed / x hours = 1 shed / 1.5 hours.
1/2 + 1/x = 1/1.5 Put the fractions over a common denominator.
(x + 2) / 2x = 1 / 1.5 Cross Multiply
1.5(x + 2) = 2x Remove the Brackets.
1.5x + 3 = 2x Subtract 1.5x from both sides
3 = 2x - 1.5x
3 = 0.5x Multiply both sides by 2
6 = x
It would take Al 6 hours to do the shed on his own.

3(2x+d)+c(x+5)=10x+17 find c and d
Answer:
c = 4, d = - 1
Step-by-step explanation:
Expand and simplify left side, then compare coefficients of like terms on the right side, that is
3(2x + d) + c(x + 5) ← distribute parenthesis
6x + 3d + cx + 5c
= x(6 + c) + 3d + 5c
Compare terms with those on the right side
coefficients of x- terms
6 + c = 10 ( subtract 6 from both sides )
c = 4
--------------
constant terms
3d + 5c = 17, that is
3d + 5(4) = 17
3d + 20 = 17 ( subtract 20 from both sides )
3d = - 3 ( divide both sides by 3 )
d = - 1
The value of c and d if 3(2x+d)+c(x+5)=10x+17 is 4 and -1 respectively
Given the equation:
3(2x+d)+c(x+5)=10x+17
Expand the bracket
6x + 3d + cx + 5c = 10x + 17
Collect the like terms
6x+cx + 3d + 5c = 10x + 17
x(6+c) + 3d + 5c = 10x + 17
Compare the coefficients of x on both sides
x(6+c) = 10x
6+c = 10
c = 10 - 6
c = 4
Similarly:
3d + 5c = 17
3d + 5(4) = 17
3d + 20 = 17
3d = 17 - 20
3d = -3
d =-3/3
d = -1
Hence the value of c and d if 3(2x+d)+c(x+5)=10x+17 is 4 and -1 respectively

Hope it will help :)❤
Answer:
V = 130.83
Step-by-step explanation:
The equation for the volume of a cone is:
[tex]V =\frac{ \pi r^2h}{3}[/tex]
we can see that r = 5, and h = 5
we will use 3.14 for the value of pi
so, we just fill in the equation with the values we know and solve :)
[tex]V=\frac{\pi r^2h}{3} \\V=\frac{(3.14) (5)^2(5)}{3}\\V=\frac{(3.14) (25)(5)}{3} \\V=\frac{392.5}{3} \\V= 130.8333 (approx.)[/tex]
the question wants the nearest hundred, so the final answer is
V = 130.83

Answer:
( x, y ) = ( 4, 1/3)
Step-by-step explanation:
x - 3y = 3
2x +9y = 11
1. substitute the value of x
x= 3 + 3y
2x + 9y = 11
2. solve equation
2 (3 + 3y) +9y = 11
3. substitute the value of y
y = 1/3
4. solve equation
x = 3 + 3 x 1/3
x = 4
5. check solution
(x, y) = ( 4, 1/3 )
check x ----> 4 - 3 x 1/3 = 3
check y ------> 2 x 4 + 9 x 1/3 = 11
for x----> 3=3
