Answer:
1 1/5 hours
Step-by-step explanation:
Tiana takes two hours to complete a task
Elena takes three hours to complete the same task
How long will it take for Tiana and elena to complete the task if they work together
This is calculated as:
1/2+ 1/3 = 1/T
Lowest common denominator = 6
Hence:
3 + 2/6 = 1/T
5/6 = 1/T
Cross Multiply
5T = 6
T = 6/5
T = 1 1/5 hours

Answer:
Step-by-step explanation:
Explicit formula of a G.P. is given by,
[tex]a_n=a(r)^{n-1}[/tex]
Here, [tex]a_n[/tex] = nth term
a = First term
n = number of term
r = common ratio
Given sequence is 3, 6, 12, .......
a = 3
r = [tex]\frac{6}{3}[/tex] = 2
Therefore, explicit formula will be,
[tex]a_n=3(2)^{n-1}[/tex]
Option (3) is the answer.
Parent function → f(x) = 3ˣ
Transformed function → g(x) = [tex]3^{x+5}[/tex]
Since, g(x) = f(x + 5)
Therefore, function 'f' has been shifted 5 units left.
Option (1) is the answer.
Renting a bicycle costs $10 for the first hour and $5 for each additional hour.
Let x represent the number of additional hours. If you have $20 to spend, which of the
equations below could be used to find how many hours you can rent a bicycle?
Does anyone know the answer to this ?

Answer:
G: $27
H: $25
Step-by-step explanation:
In each case, the "initial cost" is the cost when the number of hours is zero.
For company G, it is ...
c = 27 + 10·0
c = 27
For company H, it is 25 (corresponds to Hours = 0).
__
The initial costs are ...
G: $27
H: $25
_____
Additional comment
The cost per hour is found from the equation by looking at the coefficient of h. It is $10 per hour for Company G.
The cost per hour is found from the table by looking at the increase when the number of hours increases by 1. For 1 hour, the cost goes from 25 to 32, an increase of $7 for 1 hour. The cost is $7 per hour for Company H.

The volume of a rectangular prism is 360 cm^3. If the length of the prism is 12 cm and the width is 5 cm, what is the surface area of the prism?
Answer:
C) 324 cm^3
Step-by-step explanation:
So you know the volume and 2 side lengths. 360 divided by 12 divided by 5 to find the third side. The third side is 360 / 60 (answer of 12x5), which is 6. Surface area of prism is 324 (c)

What is the 5th term in the sequence 64, 16, 4 ?
Answer: 1
Step-by-step explanation:
Answer:
1/4 because
1st term 64 : 64/4 = 16
2nd term 16 : 16/4 = 4
3rd term 4 : 4/4 = 1
4th term 1 : 1/4 = 1/4
5th term 1/4

Slope intercept form
Given:
The equation of the parallel line is
[tex]y=-\dfrac{5}{2}x+7[/tex]
The required line passes through the point (-4,1).
To find:
The equation of line in slope slope intercept form.
Solution:
The slope intercept form of a linear function is
[tex]y=mx+b[/tex]
Where m is slope and b is y-intercept.
On comparing the equation [tex]y=-\dfrac{5}{2}x+7[/tex] with slope intercept form, we get
[tex]m=-\dfrac{5}{2}[/tex]
We know that the slopes of parallel lines are always same. So, the slope of the required line is [tex]m=-\dfrac{5}{2}[/tex].
The line passes through the point (-4,1) with slope [tex]m=-\dfrac{5}{2}[/tex]. So, the equation of line is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-(1)=-\dfrac{5}{2}(x-(-4))[/tex]
[tex]y-1=-\dfrac{5}{2}(x+4)[/tex]
[tex]y-1=-\dfrac{5}{2}x-10[/tex]
Adding 1 on both sides, we get
[tex]y=-\dfrac{5}{2}x-10+1[/tex]
[tex]y=-\dfrac{5}{2}x-9[/tex]
Therefore, the correct option is C.

The Nike store is having a SALE!!! A toddler suit with an original cost of $54 is marked down to $22.95. How much is the discount?What is the percentage discount?
Answer:
The Discount Percent is 57.50% and the Discount Amount is $31.05
Step-by-step explanation:
To find the discount percent you use the formula D = (L - S) / L x 100. To find the discount amount you take the inital list price and subtract it from the sale price.
Nancy lives in a state where sales tax is 9%. This means you can find the total cost of an item, including tax, by using the expression c + 0.09c, where c is the pre-tax price of the item.
Use the expression to find the total cost of an item that has a pre-tax price of $84.00.
9514 1404 393
Answer:
$91.56
Step-by-step explanation:
We can simplify Nancy's cost expression to ...
c +0.09c = c(1 +0.09) = 1.09c
The the total cost of the item of interest is ...
(1.09)($84) = $91.56

Find the equation of the line given the two points below
A(−3,−2) B(6,−8)
Answer:
y = -2/3x - 4
Step-by-step explanation:
Formula: y = mx + b
m (slope)
b (y-intercept)
Slope Formula: y2 - y1 ÷ x2 - x1
Substitute: -8-(-2) = -8+2 = -6
6-(-3) = 6+3 = 9
-6/9 (funny, I know)
Simplify --> -2/3
slope = -2/3
Substitute for the y-intercept --> to do this, we plug in a coordinate pair
-8 = -2/3(6) + b
-8 = -4 + b => add 4 to both sides
b = -4, and thus, our y-intercept is -4
Plug our values into the formula: y = mx + b
y = -2/3x + (-4)
simplify to get our final equation
y = -2/3x - 4
