Answer:
y=2x+24 is you're answer
Answer:
I'm pretty sure it's y=2x+24
Step-by-step explanation:
The slope intercept formula is y=mx+b. So to get the equation into that form you would have to get y by itslef, which means you would have to subtract 8x from both side. And then you can't have a number in front of the y so you have to divide by that for all of the terms.This then gives you your answer.

If cost price =x
If selling price =242
If profit =z
If profit percent =10%
Find the value of z and x
Answers
z = 22
Explanation:
SP = selling price
CP = cost price
Profit % = (SP - CP) / CP x 100%
10% = (242 - x) / x • 100%
10/100 = (242 - x)/x • 100/100
1/10 = (242 - x)/x • 1
1/10 • x = 242 - x
x/10 = 242 - x
x/10 • 10 = (242 - x) • 10
x = 2420 - 10x
x + 10x = 2420
11x = 2420
x = 2420/11
x = 220
Profit = SP - CP
z = 242 - x
z = 242 - 220
z = 22

Answer:
y=67.7 Degrees
Step-by-step explanation:
You're given the opposite and adjacent sides to angle Y, so we use Tan to find the angle:
Tan(y)= 100/41
We then inverse tan to isolate y
y=tan^-1 100/41
y=67.7 Degrees

What is the Greatest Common Denominator or factor between 244 & 48
Answers
Answer:
GCF = 4.
Step-by-step explanation:
Find the prime factors:
48 = 2*2*2*2*3
244 = 2*2*61
The greatest common factor, the GCF) (picking out the common values) =
2 *2 = 4.
A really clever way of finding the GCF of 2 numbers is Euclid's algorithm. It can be used for very large numbers where it would be time consuming and/or rather difficult to find prime factors:
Given two whole numbers where a is greater than b, do the division a ÷ b = c with remainder R.
Replace a with b, replace b with R and repeat the division.
Repeat step 2 until R=0.
When R=0, the divisor, b, in the last equation is the greatest common factor.
So applying this to our problem:
244 / 48 = 5 remainder 4
Replacing a (244) with 48 and b (48) with R (4):-
48/4 = 12 remainder 0.
So the GCF is 4.

What is a number system?A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set in a consistent manner using digits or other symbols. In different numeral systems, the same sequence of symbols can represent different numbers.
Given that the sum of two numbers is 48. if the smaller number is subtracted from the larger the difference is 12. The two numbers will be calculated as,
x + y = 48
x - y = 12
________
2x = 60
x = 30
y = 30 - 12
y = 18
Therefore, the value of the larger number is 30 and the value of the smaller number is 18.

Find the Perimeter & Area for the following circle.
use 3.14 for Pi
Round to the tenths place
Answers
Answer:
A = 28.3 cubic inches; P = 20.1 inches
Step-by-step explanation:
Looks like 3/4 of a full circle
The area of a circle is calculated with the formula: [tex]\pi r^{2}[/tex]
Since the problem wants pi = 3.14, we use 3.14 instead of pi in the equation.
The radius is given as 3 inches
Area = [tex]3.14*3^{2} = 3.14*9 = 28.26[/tex] cubic inches = 28.3 cubic inches
------------------------
Perimeter is calculated with [tex]2\pi r[/tex].
But this is 3/4 of a circle with an additional two 3-inch sides
Perimeter = [tex]\frac{3}{4}*2\pi r[/tex] + 2(3) = 14.1 + 6 = 20.1 inches

A baker charges $30 for each batch of cupcakes she makes. She adds $0.09 for each frosting flower. Write an expression to represent the total cost of a batch of cupcakes with frosting flowers. Operation Clues→ Variable→ Define a variable→ Expression→
Answers
Answer:
[tex]30+0.09x[/tex]
Here, [tex]x[/tex] denotes number of frosting flowers
Step-by-step explanation:
Let [tex]x[/tex] denotes number of frosting flowers.
Amount charged by baker for each batch of cupcakes = $30
Amount charged for each frosting flower = $0.09
So,
Amount charged for [tex]x[/tex] frosting flowers = [tex]\$0.09x[/tex]
Therefore,
Total cost of a batch of cupcakes with frosting flowers = [tex]30+0.09x[/tex]

Factorize
(x+y)² + (x+ y)(x- y) + (x+ y)(x- y) + (x– y)²
= (x+y)[x+y+(x-y)] +(x-y)[(x+y)+(x-y)]

Complete question is;
A fair coin should land showing tails with a relative frequency of 50% in a long series of flips. Felicia read
that spinning-rather than flipping-a US penny on a flat surface is not fair, and that spinning a penny
makes it more likely to land showing tails. She spun her own penny 100 times to test this, and the penny
landed showing tails in 60% of the spins.
Let p represent the proportion of spins that this penny would land showing tails.
What are appropriate hypotheses for Connor's significance test?
A. H_0 : p = 50% H_1 : p > 60%
B. H_0: p = 50% H_1: p > 50%
C. H_0: p = 50% H_1: p < 50%
D. H_0 : p = 60% H_1 : p < 60%
Answer:
Option B is correct
Step-by-step explanation:
From the question it is clear that;
The population proportion is 50% because it is not associated with any sample size.
However, the sample size is 100 and the sample proportion from this 100 is 60%.
But we don't define our hypothesis based on the sample proportion.
Now we want to find the probability that spinning a penny makes it more likely to land showing tails.
Thus we define the hypothesis as;
Null hypothesis; H0 : p=50%
Alternative hypothesis; H1 : p>50%

Answers
Answer:A he is correct because the inner circle is a dilation of the outer circle
Step-by-step explanation: just did the test
The statement "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.
What is dilation?Dilation is the process of modifying the size of an item or form by reducing or expanding its dimensions according to specific scaling variables.
The radius of the inner circle is 2 units, while the radius of the outer circle is 5 units.
Since dilations provide similar figures because multiplying by the scale factor yields proportionate sides while keeping the angle measure and form constant.
Troy is accurate if he claims the two circles are similar.
Hence, the statement (A) "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.

P varies inversely with x. If P = 7 when x = 8, find the value of P when x = 7. A. 0.125 B. 1 C. 7 D. 8
Answers
Step-by-step explanation:
P = 8
Step-by-step explanation:
Given that P varies inversely with x then the equation relating them is
P = \frac{k}{x} ← k is the constant of variation
To find k use the condition P = 7 when x = 8 , then
7 = \frac{k}{8} ( multiply both sides by 8 )
56 = k
P = \frac{56}{x} ← equation of variation
When x = 7 , then
P = \frac{56}{7} = 8
