Step-by-step explanation:
Consider the properties:
[tex]\boxed{(x^a)^b=x^{a\cdot b}}[/tex]
[tex]\boxed{x^a \cdot x^b=x^{a+b}}[/tex]
[tex]\therefore (x^3)^6 \cdot (x^2)^9= x^{18} \cdot x^{18}= x^{36}[/tex]
Answer is 36

Three times the sum of 7 and a number is 24
Answer:
The number is:
1
Step-by-step explanation:
3(7+a) = 24
3*7 + 3*a = 24
21 + 3a = 24
3a = 24 - 21
3a = 3
a = 3/3
a = 1

Answer:
55°
Step-by-step explanation:
What we have are vertical angles. Vertical angles are angles directly opposite to one another.
Importantly, the measures of vertical angles are equivalent. Thus, set the expressions to each other and solve for x:
[tex]3x+34=7x+6[/tex]
Subtract 3x from both sides:
[tex]34=4x+6[/tex]
Subtract 6 from both sides:
[tex]28=4x[/tex]
Divide everything by 4:
[tex]7=x[/tex]
Flip:
[tex]x=7[/tex]
Now, substitute this back into either of the equations since we know they are the same:
[tex]3x+34\\=3(7)+34[/tex]
Multiply:
[tex]=21+34[/tex]
Add:
[tex]=55[/tex]
So, the angle is 55°
Angela tried to solve an equation step by step. \begin{aligned} \dfrac34+m&=\dfrac54\\\\ \dfrac34+m-\dfrac34&=\dfrac54+\dfrac34&\green{\text{Step } 1}\\\\ m&=2&\blue{\text{Step } 2} \end{aligned} 4 3 +m 4 3 +m− 4 3 m = 4 5 = 4 5 + 4 3 =2 Step 1 Step 2 Find Angela's mistake.
Answer:
The mistake she made was ; She didn't change the sign when subtracting -3/4 from both sides
She wrote 5/4+3/4 instead of 5/4-3/4
Step-by-step explanation:
Correct solution:
[tex] \frac{3}{4} + m = \frac{5}{4} [/tex]
Subtract-3/4 from both sides
[tex] \frac{3}{4} - \frac{3}{4} + m = \frac{5}{4} - \frac{3}{4} [/tex]
Simplify
[tex]m = \frac{5}{4} - \frac{3}{4} \\ m = \frac{1}{2} [/tex]
The mistake Angela made was when she subtracted -3/4 from both sides, she didn't change the sign and She wrote 5/4 + 3/4 instead of 5/4-3/4.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that performs the arithmetic operations are called arithmetic operators.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
We have given the expression as
⇒ 3/4 + m = 5/4
The mistake Angela made was when she subtracted -3/4 from both sides, she didn't change the sign.
She wrote 5/4 + 3/4 instead of 5/4-3/4
Here is the correct work :
Subtract 3/4 from both sides from the equation,
⇒ 3/4 + m - 3/4 = 5/4 - 3/4
⇒ m = (5 - 3)/4
⇒ m = 2/4
⇒ m = 1/2

given that the total surface area of a cuboid with a square base is 66cm^2 and the total length of the sides is 40c. Find the possible volume of the cuboid.
Answer:
660cm^3
Step-by-step explanation:
to find the volume of a square with surface area, you multiply the base by the height. So the base is 66 and the height is 10(because 40/4=10). Then 66x10=660. So 660cm^3 would be your answer. Hope that helps!
Answer:
36 cm³
≈ 35.85 cm³
Step-by-step explanation:
Given cuboid with:Total surface area = 66 cm²Total length of the sides = 40 cmTo find:Volume of cuboidSolutionLet side of the base be x and height be y
Then we have equatins for total surface area and total side length:
2*x² + 4*xy = 66 ⇒ x² + 2xy = 332*4x + 4y = 40 ⇒ 2x + y = 10 ⇒ y = 10 - 2xSubstituting y in the first equation:
x² + 2x(10 - 2x) = 33x² + 20x - 4x² = 33-3x² + 20x - 33 = 03x² - 20x + 33 = 0Solving the quadratic equation we get roots of:
x₁ = 3 cmx₂ = 11/3 cmFor x = 3, the value of y:
y₁ = 10 - 2x = 10 - 6 = 4 cmFor x = 11/3, the value of y:
y₂ = 10 - 2x = 10 - 22/3 = 8/3 cmBased on the found values we get 2 possible volumes:
V = base * height = x²yV₁ = 3²*4 = 36 cm³V₂ = (11/3)²*8/3 ≈ 35.85 cm³A beekeeper has 65,000 female bees and 700 male bees in one colony.

Hayden places these four blocks into a bag. A B С He picks one block without looking. What is the probability that the block Hayden picks has a letter on it? . A 1/4 B 1/3 C 2/3 D 3/4
Answer:
Option D. 3/4
Step-by-step explanation:
From the question given above, we obtained the following information:
Block with letter = 3
Block with symbol = 1
Total = 4
Thus,
Sample space (S) = 4
Event of block with letter (nBl) = 3
Event of block with symbol (nBs) = 1
Finally, we shall obtain the probability of picking a block with letter as follow:
Sample space (S) = 4
Event of block with letter (nBl) = 3
Probability of picking a block with letter, P(Bl) =?
P(Bl) = nBl/nS
P(Bl) = 3/4
Therefore, the probability of picking a block with letter is 3/4.
A rectangle has sides that measure 12x + 7 units long and 9x+ 11 units long. What is the expression that represents the perimeter of the rectangle?
Answer: P= 2{(12x+7) + (9x+11)} or 42x + 36
Step-by-step explanation:
The formula for the perimeter of a rectangle is P=2(l+w)
P= 2{(12x+7) + (9x+11)}

You start at (1,0) And move down 2 units and left 4 units where do you end
Answer:
(-3,-2)
Step-by-step explanation:
Starting at the point (1, 0)
Now we move don 2 units (so the y-value reduces in two units) making now the point (1,0-2) which is (1, -2)
then we move to the left 4 units (so the x-value has now to be decreased in 4 units) making the point: (1-4, -2) which is (-3, -2)
Answer:
It would be -2,4.
Step-by-step explanation:
you start at (1,0) and go down 2 to -2 then left 4 you would land on -2,4

The associative property allows us to change the grouping of the factors that are
multiplied together to create what?
Answer:
Step-by-step explanation:equivalent expressions
The associative property allows us to change the grouping of the factors that are multiplied together to create an equivalent expression.
When the grouping of the addends is changed, the sum stays the same. The Associative Property of Multiplication states that when the grouping of the factors is changed, the product is the same. It is also called the Grouping Property of Multiplication. Always multiply the numbers inside the parentheses first.

if qr=8x+1 and qs=20x-26 than what is rs
Answer:
Step-by-step explanation:
20x - 26 = 8x + 1
12x - 26 = 1
12x = 27
x = 27/12 = 2 3/12 = 2 1/4 = 2.25
8(2.25) + 1 + 20(2.25) - 26
18 + 1 + 45 - 26
19 + 45 - 26
64 - 26 = 38 = rs
The value of rs is 38 for the given expression.
What is a balancing equation?"A balanced equation is an equation where both sides are equal to the same amount. The answer to the expression on the left side of the equals sign (=) should be equal to the value on the right side of the equals sign".
For the given situation,
The two equations are
qr=8x+1 and
qs=20x-26
On equating these two equations,
[tex]8x+1=20x-26[/tex]
⇒ [tex]12x=27[/tex]
⇒ [tex]x = 2.25[/tex]
To find rs, we need to add both equations.
[tex]rs=8x+1+20x-26[/tex]
⇒ [tex]rs=8(2.25)+1+20(2.25)-26[/tex]
⇒ [tex]rs=38[/tex]

• Then find the length of each segment.
11. HJ=6x-5
JK=4x-6
KH=129
12. HJ=4x-15
JK=5x-6
KH=15
Please show all work and not just answers.
Answer:
11. HJ = 79; JK = 50
12. HJ = 1; JK = 14
Step-by-step explanation:
The segment addition postulate tells you the total length is the sum of the segment lengths.
__
11. HJ + JK + HK
(6x -5) +(4x -6) = 129
10x = 140 . . . . add 11
x = 14 . . . . . . . divide by 10
6x -5 = 6(14) -5 = 79 = HJ
4x -6 = 4(14) -6 = 50 = JK
__
12. HJ + JK = HK
(4x -15) +(5x -6) = 15
9x = 36 . . . . . add 21
x = 4 . . . . . . . .divide by 9
4(4) -15 = 1 = HJ

If m angle ABD=79 degrees , what are m angle ABC and m angle DBC
Answer:
m<ABC = 45
m<DBC = 34°
Step-by-step explanation:
Given:
m<ABD = 79°
m<ABC = (8x - 3)°
m<DBC = (5x + 4)°
Step 1: Generate an equation to find the value of x
m<ABC + m<DBC = m<ABD (angle addition postulate)
(8x - 3) + (5x + 4) = 79
Solve for x
8x - 3 + 5x + 4 = 79
13x + 1 = 79
Subtract 1 from both sides
13x + 1 - 1 = 79 - 1
13x = 78
Divide both sides by 13
x = 6
Step 2: find m<ABC and m<DBC by plugging the value of x into the expression of each angle
m<ABC = (8x - 3)°
m<ABC = 8(6) - 3 = 48 - 3 = 45°
m<DBC = (5x + 4)°
m<DBC = 5(6) + 4 = 30 + 4 = 34°
"one less than the product of a number and 3 is 5 more than the number itself"
Answer:
the number is 3
Step-by-step explanation:
Perhaps you'd like to find the number.
If n represents the number, we can write the relationship as ...
3n -1 = n +5
Adding 1-n to both sides gives ...
2n = 6
n = 3 . . . . divide by 2
The number is 3.

Check
The product of the number and 3 is 9. One less is 8. That is 5 more than the number itself: 8 = 3 + 5.

mZCBD = 9x + 17°
Find m2CBD:
А
B
D
Answer:
∠CBD = 125°
Step-by-step explanation:
The angle sum theorem tells you that ...
∠ABC +∠CBD = ∠ABD
8x -41° +9x +17° = 180° . . . . . . a "straight angle" has a measure of 180°
17x -24° = 180° . . . simpify
17x = 204° . . . . . . add 24°
x = 12° . . . . . . . . . . divide by 17
Now the measures of the angles can be found from their expressions.
∠ABC = 8(12) -41° = 55°
∠CBD = 9(12) +17° = 125°
