Answer:
20% increase
Step-by-step explanation:
To find the percent increase, you can divide the increase value by the original: 30/25 = 1.2 --> 120%. Next, since they ask for the percent of increase, you can subtract 1 or 100% from your answer which would give you a final answer of 20% increase.

1 and 2 are supplements, 3 and 4 supplements and 1 =4. prove 2=3
Step-by-step explanation:
Supplementary angles are angles that have the sum of their angles to be 180°. Hence if <1 and <2 are supplements, then <1+<2 = 180°.... 1
Similarly if <3 and <4 are supplements, then <3+<4 = 180° ....... 2
Equating the left hand side of both equations since they are both equal to 180°, we will have;
<1+<2 = <3+<4 ....... 3
From the question we are told that <1 = <4, substituting this condition into equation 3;
From 3; <1+<2 = <3+<4
<4+<2 = <3+<4 (since <1 = <4)
subtract <4 from both sides
<4+<2 -<4= <3+<4 -<4
<2 = <3 (Proved!)

For the last 4.5 hours, the temperature has decreased at a rate of 2.8 Degrees Fahrenheit per hour. Which best represents the overall change in temperature over this time period? –12.6 Degrees Fahrenheit –1.6 Degrees Fahrenheit 1.6 Degrees Fahrenheit 12.6 Degrees Fahrenheit?
Please help me!
Answer:
The overall change in temperature over the time period ∆T = -12.6°F
Step-by-step explanation:
Rate of change of temperature r = -2.8°F per hour
Time t = 4.5 hours
The overall change in temperature ∆T = Rate of change of temperature × time period
∆T = r × t
∆T = -2.8°F per hour × 4.5 hours
∆T = -12.6°F
The overall change in temperature over the time period is -12.6°F

why are circles so important to these constructions write out a concise explanation of the importance of circles in creating equilateral triangles why did euclid use circles to create his equilateral triangles in proposition 1 how does construction of a circle ensure that all relevant segments are of equal length
Answer:
A circle is the set of points at a certain distance from the center. Take the desired base. Put the points of the compass on each end. Leaving one point in place rotate the other to create an arc. Do the same with the other end. Where the arcs meet is the apex of the triangle. Connect two sides to the base. The sides are the desired length because they form a radius of a circle.

Answer:
1.) [tex]slope=2[/tex]
2.) [tex]slope=-3[/tex]
3.) [tex]slope=\frac{1}{4}[/tex]
4.) [tex]slope=-\frac{4}{5}[/tex]
Step-by-step explanation:
The unit rate is also known as slope. Slope is the change in the y values over the change in the x values:
[tex](x_{1},y_{1})\\\\(x_{2},y_{2})\\\\\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=slope[/tex]
However, with certain graphs, the slope can be found in a simpler manner.
You start at one point and move across the y-axis, then move along the x-axis until you reach another point on the same line. Make sure you move on the y-axis first, then the x-axis. Record the slope as spaces moved in each [tex]\frac{y}{x}[/tex] When you move up, the number will be positive [tex](\frac{+y}{x})[/tex]. If you move down, the number will be negative [tex](\frac{-y}{x})[/tex].If you move to the right, the number will be positive [tex](\frac{y}{+x})[/tex]. If you move to the left, the number will be negative [tex](\frac{y}{-x})[/tex].x^2 + 11x + 24

Choose 1 answer:
A)-1/3
B)-3
C)1/3
D)3
Answer:
The answer is option BStep-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-1,8) and (3,-4)
The slope is
[tex]m = \frac{ - 4 - 8}{3 - - 1} = \frac{ - 12}{4} = - 3 \\ [/tex]
We have the final answer as

(PLEASE HELP ME DX PLEASE) Nate would like to purchase a new laptop for school from Best Buy. The store is offering a $100 mail in rebate on all Lenovo Laptops. Nate is planning to spend anywhere between $300 - $500. Sales tax is 8% of the total cost after the rebate has been given.
(a) Write the compound inequality to represent this scenario.
(b) What price range of laptops can Nate look at so that he meets his budget. Show your work. Be sure to
explain what your answer means.
Answer:
Part A)
[tex]300\leq 1.08(x-100)\leq 500[/tex]
Part B)
[tex]377.78\leq x\leq 562.96[/tex]
Nate wants the original price of the laptop to be between approximately $378 or $563.
Step-by-step explanation:
Part A)
Let's let x be the price of the new laptop.
Since the store is offering a $100 rebate (discount), this means that the total cost of the laptop before tax is:
[tex]x-100[/tex]
So, the total price of the laptop after the 8% tax is:
[tex]1.08(x-100)[/tex]
Since Nate is planning to spend between $300 and $500, this means that we can write the following compound inequality:
[tex]300\leq 1.08(x-100)\leq 500[/tex]
Part B)
To find the range of the price of laptops, let's find the solution to our inequality.
To do so, let's solve them individually. So, let's first find our minimum price:
[tex]300\leq1.08(x-100)[/tex]
Divide both sides by 1.08:
[tex]277.78\leq x-100[/tex]
Add 100 to both sides:
[tex]377.78\leq x[/tex]
So, Nate wants the laptop to be at least approximately $378.00.
Now, let's find our maximum price:
[tex]1.08(x-100)\leq 500[/tex]
Divide both sides by 1.08:
[tex]x-100\leq462.96[/tex]
Add 100 to both sides:
[tex]x\leq 562.96[/tex]
So, Nate wants the maximum price of the laptop to be about $563.00.
So, our compound inequality is:
[tex]377.78\leq x\leq 562.96[/tex]
This means that Nate wants the original price of the laptop to be between approximately $378 or $563.
And we're done!
Answer:
This would be the compound inequality formula for the given situation. This is because Nate is planning on spending somewhere between 300 and 500 dollars. Therefore the price (represented by the variable p) needs to be greater than or equal to 300 but at the same time less than or equal to 500. But this is after the rebate and sales tax have been calculated into the laptop's price. Which in this scenario, the rebate needs to be applied first and then the sales tax is applied after as 1.08 in order to apply the 8% onto the price itself.

What is the slope-intercept form of the equation of the line that contains the points(-3, -3)and(4, 5)?
Answer:
y = 8/7x+3/7
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 5 - -3)/( 4 - -3)
= ( 5+3)/ ( 4+3)
=8/7
The slope intercept form of the equation is y = mx+b
y = 8/7x+b
Substitute a point into the equation
5 = 8/7 *4 +b
5 = 32/7 +b
35/7 = 32/7 +b
Subtract 32/7 from each side
35/7 - 32/7 =b
3/7 =b
y = 8/7x+3/7
Answer:
y = 8/7x+3/7
