Answer:
A: 6x^8y^5
B: 4x^4z^8
C:12a^9b^7
D:6s^9t^3
Step-by-step explanation:
When you multpily exponents with the same base you just add them
You still multiply the real numbers like you normally would though
so we have
3x²y^4*2x^6y
To do this you multiply 3*2=6
add the exponents on x^2 and x^6=x^8
and add the exponents on y (which is equal to y^1) and y^4=y^5
put these together and get 6x^8y^5
B: I won't explain it twice because it's the same process
I get 4x^5z^8
C: 12a^9b^7
D: 6s^9t^3

11. An employee at the recreation center earns $84.00 for working 7 hours. At
this hourly rate, what should the employee earn for 40-hour work week?
A. $12.00
B. $ 480.00
C. $ 280.00
D. $ 21.00
PLEASE ANSWER
Answer:
B. $480.00
Step-by-step explanation:
Find the hourly rate by dividing 84 by 7:
84/7
= 12
Find how much they will make in the 40 hour week by multiplying 40 by 12:
40(12)
= 480
So, the correct answer is B, $480.00

The roller coaster has a mass of 600 kg and has a potential energy of 46,000J. What is the height of the roller coaster car?
Answer:
The height of the roller coaster car is: h = 7.8 m
Step-by-step explanation:
Given
Mass m = 600 kg
Potential Energy P.E = 46,000J
To determine
Height h = ?
Using the formula
P.E = mgh
Here:
m is the massg is the gravitational acceleration (9.8 m/s²)h is the heightso substituting m = 600 kg, P.E = 46,000J, and g = 9.8
P.E = mgh
46000 = 600 × 9.8 × h
h = 46000 / 5880
h = 7.8 m
Therefore, the height of the roller coaster car is: h = 7.8 m

Acircular ring has across -section as shown .If the outer radias 20 mm and the inner radius 16 mm .Calculate the cross - section area of the ring .
Answer:
452.45mmm^2
Step-by-step explanation:
Step one:
Given data
outer radius R= 20mm
inner radius r= 16mm
let us find the area of the outer circle
Area= πR^2
Area= 3.142*20^2
Area= 3.142*400
Area= 1256.8 mm^2
let us find the area of the inner circle
Area= πr^2
Area= 3.142*16^2
Area= 3.142*256
Area= 804.35 mm^2
Hence the area of the section is
Area of outer- Area of inner
=1256.8-804.35
=452.45mmm^2

Find the total cost. $20 meal; 9% sales tax; 20% gratuity after the sales tax has been added Group of answer choices
Answer: $26.16
Step-by-step explanation:
Total cost = Meal cost + Sales tax + Gratuity after sales tax
Sales tax = 9% * 20
= $1.80
Gratuity after sales tax is added = 20% * (20 + 1.80)
= $4.36
Total cost = 20 + 1.80 + 4.36
= $26.16
Suppose that LMN is isosceles with base LN suppose that M
Given:
In an isosceles triangle LMN, LM=MN.
[tex]m\angle M=(3x+17)^\circ,m\angle L=(2x+36)^\circ[/tex]
To find:
The measure of the angles L, M and N.
Solution:
In triangle LMN,
[tex]LM=MN[/tex] (Given)
[tex]m\angle N=m\angle L=(2x+36)^\circ[/tex] (Base angles of an isosceles triangle are equal)
Now,
[tex]m\angle L+m\angle M+m\angle N=180^\circ[/tex]
[tex](2x+36)^\circ+(3x+17)^\circ+(2x+36)^\circ=180^\circ[/tex]
[tex](7x+89)^\circ=180^\circ[/tex]
[tex](7x+89)=180[/tex]
On further simplification, we get
[tex]7x=180-89[/tex]
[tex]7x=91[/tex]
[tex]x=\dfrac{91}{7}[/tex]
[tex]x=13[/tex]
The value of x is 13. Using this value, we get
[tex]m\angle L=(2(13)+36)^\circ[/tex]
[tex]m\angle L=(26+36)^\circ[/tex]
[tex]m\angle L=62^\circ[/tex]
Similarly,
[tex]m\angle M=(3(13)+17)^\circ[/tex]
[tex]m\angle M=(39+17)^\circ[/tex]
[tex]m\angle M=56^\circ[/tex]
And,
[tex]m\angle N=m\angle L[/tex]
[tex]m\angle N=62^\circ[/tex]
Therefore, the measure of angles are [tex]m\angle L=62^\circ,m\angle M=56^\circ,m\angle N=62^\circ[/tex].

3 Find the other endpoint of the line segment with the given endpoint and midpoint.
Answer:
distance between (F,G) and (H,J) = 9.02
distance between (F,H) and (G,J) = 3.8
distance between (F,J) and (G,H) = 3.8
Step-by-step explanation:
Distance between (F,G) and (H,J)
d=√(7.2−3.9)2+(10.6−2.2)2
d=√(3.3)2+(8.4)2
d=√10.89+70.56
d=√81.45
d=9.024965
Distance between (F,H) and (H,J)
d=√(2.2−3.9)2+(10.6−7.2)2
d=√(−1.7)2+(3.4)2
d=√2.89+11.56
d=√14.45
d=3.801316
Distance between (F,J) and (G,H)
d=√(2.2−3.9)2+(7.2−10.6)2
d=√(−1.7)2+(−3.4)2
d=√2.89+11.56
d=√14.45
d=3.801316

Step 1: Identify Variables
Leg a = 9
Leg b = 3
Hypotenuse c = x
Step 2: Solve for x
Substitute [PT]: 9² + 3² = x²Rearrange: x² = 9² + 3²Exponents: x² = 81 + 9Add: x² = 90Isolate x: x = 3√10To find the value of x we can apply Pythagoras theorem in this right angled triangle.
So let's apply!

[tex] \sf{ : \implies {x}^{2} = {9}^{2} + {3}^{2} }[/tex]
[tex] \sf{ : \implies {x}^{2} = 81 + 9 }[/tex]
[tex] \sf{ : \implies {x}^{2} = 90 }[/tex]
[tex] \sf{ : \implies {x} = \sqrt{2 \times 3 \times 3 \times 5} }[/tex]

Number 6 is b
Step-by-step explanation:
Brenda is deciding between two landscaping companies for her place of business. Company A charges $25 per hour and a $300 equipment fee. Company B charges $50 per hour and a $150 equipment fee. Let AA represent the amount Company A would charge for tt hours of landscaping, and let BB represent the amount Company B would charge for tt hours of landscaping. Write an equation for each situation. Determine the interval of hours, t,t, for which Company A is cheaper than Company B.
Answer:
1/6 hours
Step-by-step explanation:
Given data
Company A charges
$25 per hour and a $300 equipment fee
let the number of hours be t
and the total charges be A
A=25+300t----------------1
Company B charges $50 per hour and a $150 equipment fee.
let the number of hours be t
and the total charges be B
y=50+150t----------------2
Equate 1 and 2 we have
25+300t= 50+150t
300t-150t= 50-25
150t= 25
divide both sides by 150
t= 25/150
t=1/6 hours
Determine the solution for the equation.

After distributing, which equation is equivalent to -4(3x + 2) = 10a.-12x -8 = 10b.-12x + 8 = 10c.-12x -6 = 10d.-12x + 6 = 1
Answer:
Option A: -12x-8=10 is the correct answer.
Step-by-step explanation:
Given equation is:
-4 (3x+2) = 10
We will distribute the equation by multiplying the terms inside the brackets with -4.
Therefore,
-4*3x + 2*-4 = 10
-12x +(-8) = 10
-12x - 8 = 10
The equation -4 (3x+2) = 10 will become -12x-8=10 after distributing.
Hence,
Option A: -12x-8=10 is the correct answer.

-8 divided by -5 in fraction form
Answer:
8 / 5
Step-by-step explanation:
-8 / -5 = 8 * -1 / 5 * -1 = 8 / 5
Thank, 5 star, and brainliest if helpful
The fraction (-8)/(-5) simplifies to 8/5 which represents that the quotient is 8 units for every 5 units.
To divide -8 by -5 in fraction form, we can write it as (-8)/(-5). When dividing two negative numbers, the negative signs cancel out, resulting in a positive quotient. So (-8)/(-5) is equal to 8/5.
When we divide -8 by -5, we subtract -5 from -8 repeatedly until we can no longer subtract without going below zero.
This happens after one subtraction, resulting in a quotient of 1.
However, since both numbers are negative, the quotient is positive.
Therefore, (-8)/(-5) simplifies to 8/5.
In fraction form, 8/5 represents the result of dividing -8 by -5, indicating that the quotient is 8 units for every 5 units.
