Answer:
6
Step-by-step explanation:
8^4 is 8*8*8*8
8^2 is 8*8
therefore
(8^4) *(8^2) = (8*8*8*8)*(8*8) = 8^(4+2) = 8^6
If a line has a slope of 3/5, and you have chosen two points on the line that have a rise of 15, what is the run?
Answer:
The run is 25
Step-by-step explanation:
Mathematically, the slope of an equation is;
Slope = change in y/change in x
change in y is called the rise, change in x is called the run
slope = rise/run
3/5 = 15/run
run = 15 * 5/3
run = 25

Write the equation for a line that passes through the point (-8,2) and is parallel to 5x-4y=4. Enter your equation in slope intercept form with slope written as a fraction
Answer:
y = 5/4x + 12
Step-by-step explanation:
5x - 4y = 4
-4y = -5x + 4
y = (-5x + 4)/-4
y = 5/4x - 1
Parallel Slope ---> m = 5/4
(-8, 2)
y = mx + b
2 = 5/4(-8) + b
2 = 5 * -2 + b
2 = -10 + b
12 = b
b = 12
y = 5/4x + 12 <---- This is the answer

What is perimeter?A perimeter is a closed path that covers, surrounds, or bounds a two-dimensional shape or a one-dimensional length. The perimeter of a circle or ellipse is called its perimeter. Frame calculus has several practical applications.
To find the perimeter of a rectangle, or the distance, we must add the lengths of all four sides. This can be done efficiently by simply adding the length and width and multiplying that sum by two since there are two lengths on each side. perimeter= (Length Width) × 2 is the formula for perimeter.

you are selling pandesal to raise money for a school field trip. Pandesal with cheese cost 8.00 pesos and ube pandesal cost 9.00 pesos You need to sell at least two of each kind. You want to sell at least 180 pesos worth of pandesal. Write and graph a system of linear inequalities that represent the information given above
Answer:
Let's define:
C = number of pandesal with cheese that you sell
U = number of pandesal with ube that you sell.
If you sell these numbers of each, the total profit you get is:
C*8.00 pesos + U*9.00 pesos.
And yo want to get at least 180 pesos, then:
C*8.00 pesos + U*9.00 pesos ≥ 180 pesos.
And you also want to sell two of each, then:
C ≥ 2
U ≥2
So the system of inequalities is:
C*8.00 pesos + U*9.00 pesos ≥ 180 pesos.
C ≥ 2
U ≥2
If U is on the x-axis, and C is on the y-axis, then the graph is: (where the region at the right of the vertical line should be shaded)
Plotting the inequalities above using geogebra online graphing tool.
Let x represent the number of pandesal with cheese and y represent the number of ube with cheese
Since at least two of each kind is needed to be sold, hence:
x > 2, y > 2
At least 180 pesos worth of pandesal is needed to be sold, hence:
8x + 9y > 180

-17x = -204
What is x?
x = _
Answer:
x = 12
Step-by-step explanation:
-17x = -204 (Given)
x = 12 (division)
Negative x negative = positive
The equivalent value of the expression is x = 12
Given data ,
Let the equation be represented as A
Now , the value of A is
-17x = -204
On simplifying the equation , we get
-17x = -204
So , the left hand side of the equation is equated to the right hand side by the value of ( -204 )
Opening the parenthesis on both sides , we get
-17x = -204
Divide by ( -17 ) on both sides , we get
x = -204 / -17
x = 204 / 17
On further simplification , we get
x = 12
Therefore , the value of x = 12
Hence , the expression is x = 12

3(x+4)=6x solve for x
Answer:
x = 4
Step-by-step explanation:
(First write the equation down)
3 ( x + 4 ) = 6x
(Then use the disstributive property)
3 times x and 3 times 4
3x + 12 = 6x
(Now subtract the same values aka 3x from both sides)
3x - 3x cancels out aka is 0
6x - 3x is 3x
(You now have...)
12 = 3x
(Now you divide both sides by 3)
12/ 3 = 3x/3
12 divided by 3 is 4
the two 3s cancel out leaving you with x
(You now have your answer)
4 = x
(Write it in proper format)
x = 4

Divide £208 in the ratio 3:1
How do I do this??
Answer:
s = r1 s = 3.1 s = 3.1
or
v =a/s
v = 208/3.1
v = 67.0968
Step-by-step explanation:
The first part of the ratio would be 156. The second part of the ratio would be 52.
What is Ratio?A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other
To divide £208 in the ratio 3:1, you can use the following method:
Convert the ratio to a fraction by dividing the first number by the sum of the numbers in the ratio (3 / (3+1) = 3/4)
Multiply the fraction by the total amount you want to divide (£208)
The result will be the amount for the first part of the ratio, and the remaining amount is the second part of the ratio.
So the first part of the ratio would be: 3/4 × 208 = 156
The second part of the ratio would be: 208 - 156 = 52

Suppose aisha only reads from 10:15 a.M to 2:10 p.M and from 7:20 p.M to 9.00 p.M each day starting on monday on what day and at what time will she finish reading her book?
Complete Question
Aisha is spending a week at her family’s cottage and wants to read her favourite book, which is 400 pages long.
a) If she reads one page every 36 seconds, how many hours will it take her to read her book?
b) Suppose Aisha only reads from 10:15 a.m. to 2:10 p.m., and from 7:20 p.m. to 9:00p.m. each day, starting on Monday. On what day and at what time will she finish reading her book?
Answer:
a) 4 hours
b) Monday, 7:25 pm
Step-by-step explanation:
a) From the above question, we are told that,
She read 1 page in 36 seconds
Total number of pages in the books = 400
Hence:
1 page = 36 seconds
400 pages = x
Cross Multiply
x = 400 × 36 seconds
x = 14,400 seconds
Converting this to hours
60 seconds = 1 minute
60 minutes = 1 hour
Hence: 60 × 60 = 3600 seconds = 2 hour.
3600 seconds = 1 hour
14400 seconds = x
x = 14400/3600
x = 4 hours
Hence, it takes Aisha 4 hours to finish reading the 400 paged book
b) The number of hours between 10:15 a.m. and 2:10 p.m. is
calculated as:
2:10 pm - 10.15 am
Converting 2:10 pm to a 24 hour clock for easy calculation =
2:10 pm = 14:10 hours
Hence:
14:10 - 10:15
= 3 hours 55 minutes
Remember, from Question a, it takes Aisha 4 hours to finish reading her book and
If 10:15 a.m. to 2:10 p.m = 3 hours 55 minutes, Aisha needs 5 extra minutes to finish her book.
Therefore, she will finish reading her book at 7:25 p.m. on Monday.

A random sample of CO2 levels in a school has a sample mean of x¯=598.4 ppm and sample standard deviation of s=86.7 ppm. Use the Empirical Rule to determine the approximate percentage of CO2 levels that lie between 338.3 and 858.5 ppm. Round your answer to the nearest tenth.
Answer:
99.7%
Step-by-step explanation:
we start by getting the z-scores for the values given
We can get the z-scores using the formula below;
z-scores = (x-mean)/SD
for 338.5;
z = (338.5-598.4)/86.7 = -2.99 approximately-3
for 858.5;
z = (858.5-598.4)/86.7 = 3
so we want to get the percentages that lie within 3 standard deviations from the mean
According to the empirical rule, the percentages within 3 SD of the mean is;
100-0.15-0.15 = 99.7%

-3x is the right answer.A dilation has center (0,0). Find the image of the point L(-4,0) for the scale factor 9.
Dg (L=L(Type an ordered pair. Simplify your answer.)
Answer:
L' = (-36, 0)
Step-by-step explanation:
If the point (x, y) is dilated by a scale factor of k about the center (0, 0), then its image is the point (kx, ky)
∵ A dilation has a center (0, 0)
∵ The point L is (-4, 0)
∴ x = -4 and y = 0
∵ The scale factor of dilation is 9
∴ k = 9
→ By using the rule above
∵ kx = 9(-4) = -36
∵ ky = 9(0) = 0
∵ The image of the point L is (kx, ky)
∴ L' = (kx, ky)
∴ L' = (-36, 0)
