slope is 1.5
Step-by-step explanation:
Slope = rise over run = (y2-y1)/(x2-x1)
choose y2 and corresponding x-coordinate is x2. If we choose 27 as y2, then:
x2 = 1
x1 = -9
y1 = 2
then plug everything into the equation
(27-2)/(1-(-9))
=15/10
= 1.5
slope is 1.5

Amy has $725 in savings. She plans to save an additional $25 per month. What is the number of additional months Amy will need to save money in order to have exactly $1,000?
A.11
B.29
C.40
D.69
Answer:
11 months
Step-by-step explanation:
We know that Amy has a saving of $725 which she needs to make it up to $1000 by saving $25 each month.
This means that Amy needs to save $1000 - $725 = $275 more dollars to have exactly $1000 dollars.
If Amy saves $$25 each month, then the number of months that she needs to save money will be = 275 / 25 = 11 months

why are radioactive isotopes not useful for dating sedimentary rocks?
Sedimentary rocks can be dated using radioactive carbon, but because carbon decays relatively quickly, this only works for rocks younger than about 50 thousand years. So in order to date most older fossils, scientists look for layers of igneous rock or volcanic ash above and below the fossil.

What is |5.4|?
What is the opposite of 10?
Answer:
-10
Step-by-step explanation:
Answer:
1. 5.4
2. The additive inverse is the negative value, -10.
The multiplicative inverse (reciprocal) is 1/10.
Step-by-step explanation:
1. Since the value within the absolute value is not negative then the value remains the same.
2, The opposite of positive 10 could be -10. The reciprocal is 1/10.

Answer:
$10 an hour
Step-by-step explanation:
You go to the one hour than go up to where the line is and find out what the number is
Answer:
Step-by-step explanation:
Ok, so to solve this problem, you need to find the slope of the line. You know this is what you need to find because units for slope is the y-axis units (dollars) divided by the x-axis units (hours), and your answer must be in dollars per hour based on the question. To find your slope, you use the formula (y2-y1)/(x2-x1). Basically, pick any two points on the graph. I will use (2,20) and (4,40). Now, find the change in x (4 - 2, or 2) and the change in y (40 - 20, or 20) and divide the change in y by the change in x (20/2) to get your answer.
You have given an equal sided triangle with side length a. A straight line connects the center
of the bottom side to the border of the triangle with an angle of α. Derive an expression for
the enclosed area A(α) with respect to the angle (see drawing
Answer:
First case;
α < 90°
The area of the shaded triangle = 1/8·a²·sin(60)sin(α)csc(120 - α)
Second case;
α > 90°
The shaded area of the triangle = 1/8·a²·sin(60)sin(180 - α)csc(60 - α) + (a²·√3)/4
Step-by-step explanation:
First case;
α < 90°
The given parameters are;
The type of triangle = Equilateral triangle
The length of the sides of the triangle = a
The area of the triangle = 1/2×a×b×sinC
Where;
a and b are two legs (sides) of the triangle and C is the included angle
e/(sin(α)) = a/(2sin(120 - α)) = f/(sin60)
f = a·sin(60)/(2sin(120 - α))
The area of the triangle = 1/2 × a·sin(60)/(2sin(120 - α))×a/2 × sin(α)
By an online application, we have
1/2 × a·sin(60)/(2sin(120 - α))×a/2 × sin(α) = 1/8·a²·sin(60)sin(α)csc(120 - α)
The area of the triangle = 1/8·a²·sin(60)sin(α)csc(120 - α)
Second case;
α > 90°
The shaded area of the triangle = The area of the equilateral triangle - The unshaded area of the triangle
With an online tool, we have;
The shaded area of the triangle = (a²·√3)/4 - 1/8·a²·sin(60)sin(180 - α)csc(120 - (180 - α)
The shaded area of the triangle = 1/8·a²·sin(60)sin(180 - α)csc(60 - α) + (a²·√3)/4

Find the slope of the line y
= -1/8x + 7/6
Answer:
The slope is -1/8 and the y intercept is 7/6
Step-by-step explanation:
This equation is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -1/8 x + 7/6
The slope is -1/8 and the y intercept is 7/6
What is the slope of the line
Answer:
[tex]\huge\boxed{\frac{1}{2}}[/tex]
Step-by-step explanation:
In order to find the slope of a line, we need to find it’s rise over it’s run.
To do this, we need to find the change in y, and divide that by the change in x between any two given points.
[tex]\frac{\Delta y}{\Delta x}[/tex]
Two points on this graph that we can compare are are (-1, 3) and (1, 4).
From -1 to 1 is 2 points. So, the change in x is 2.
From 3 to 4 is 1 point. So, the change in y is 1.
Divide the change in y by the change in x:
[tex]1 \div 2 = \frac{1}{2}[/tex]
So the slope is 1/2.

what is the best estimate for the product 4 times 24
Answer:
20×4=80
4×2×10=80
Step-by-step explanation:
To estimate the result of multiplication (product), round the numbers to some close numbers that you can easily multiply mentally.
One method of estimation is to round all factors to the biggest digit (place value) they have.
you need to round 24 to the nearest ten which is 20 and leave 4 as it is

A game decreased in price by
1/3
After the reduction it was priced at £26.
What was the original price of the game??
Answer: £78
Step-by-step explanation
It decreased by 1/3 and after the reduction it was £26 so you have to get the other 2/3 so you multiply £26 by 3 to get the 3/3 that you need that will give you £78.
26 × 3 = £78
Solve for X. -15=22x+7
Answer:
x=-1
Step-by-step explanation:
-15=22x+7
Subtact 7 both sides

-22x=-22
Divide both sides by -22
-22x=-22
x=-1

If Lily got 18 questions right on a 20 questions
test, what percentage of the questions did she
get wrong?
Answer:
She got 10% of the questions wrong !
Step-by-step explanation:
To solve this problem I used cross multiplication
[tex]\frac{x}{100}= \frac{18}{20}[/tex]
18 x 100 =1800
1800 / 20 = 90
Since they are asking what she got wrong, not what she got right, you just need to subtract.
100% - 90% = 10%
hope this helped !
Answer:
10%
Step-by-step explanation:
18/20 Questions = 0.9 or 90% she got right
2/20 Questions = 0.1 or 10% she got wrong

A stock loses $1.50 each day over a five-day period. What is the total change in the value of the stock at the end of five days? (remember to have two numbers after the decimal)
Given:
A stock loses $1.50 each day over a five-day period.
To find:
The total change in the value of the stock at the end of five days.
Solution:
Stock loses each day = $1.50
We know that, loss or reduction represented as negative change.
So, change in the value of the stock per day = -$1.50
Change in the value of the stock in 5 days = 5×(-$1.50)
= -$7.50
Therefore, the change in the value of the stock at the end of five days is -$7.50. It means, the value of the stock loses $7.50 at the end of five days.
