If linda completed 20% of her science project on Monday, what percentage of her project is left to complete?
Answer:
80% because if she finished her project it would be 100%, but if we subtract 20% from 100, it would be 80% so she has 80% left to complete

Find two consecutive even integers such that the sum of the numbers is ten more than the larger number. (Must solve algebraically to receive full credit.)
Answer:
10 and 12
Step-by-step explanation:
Let the smallest number = 2x
Then the larger number is 2x + 2
2x + 2x + 2 = 2x + 2 + 10 Subtract 2x + 2 from both sides
2x = 10 Divide by 2
x = 5
The smaller number is 2x = 2 * 5 = 10
The larger number is 2x + 2 = 12
Kevin has a rectangular
swimming pools that is 12
feet by 16 feet. He wants
to put a rope diagonally
across the pool. How long
does the rope need to
be?
Answer:
20 feet long
Step-by-step explanation:
To solve this you need to use the Pythagorean theorum, [tex]a^2+b^2=c^2[/tex], where c is the length of rope needed and A and B are the side lengths. Think of it like a right triangle.
So, the equation is
[tex]12^2+16^2=c^2[/tex]
Which is then
[tex]144+256=c^2[/tex]
[tex]c^2=400[/tex]
And the possible values of c are 20 and -20.
From here we know the answer cannot be -20 because you cannot have a negatively long length of rope, so the answer must be 20 feet.
Answer:
20 feet
Step-by-step explanation:
Use Pythagoras's theorem.
[tex]A^{2}+B^{2} =C^{2} \\12^{2} +16^{2}= C^{2} \\400 = C^{2} \\\sqrt{400}= \sqrt{C^{2}\\\\[/tex]
20 = C
Write an equation in point-slope form for the line with a slope of 1/4 that passes through the point (-1, -8)
Answer:
y = 1/4 x - 31/4
Step-by-step explanation:
Slope (m) = 1/4
Point A (-1, -8)
y = mx + b
-8 = 1/4 (-1) + b
-8 + 1/4 = b
b = -32/4 + 1/4
b = -31/4
y = mx + b <-- this is a linear equation, continuing line, so there are infinite values for x and y. Therefore we don't have to plug the values of x and y in
y = 1/4 x + - 31/4
y = 1/4 x - 31/4
3 scoops of powder lemonade mix are required to make to courts of lemonade have many scoops of powder eliminate mix are required to make 3 gallons of lemonade
Answer:
I guess that the question should say:
You need 3 scoops of powder lemonade mix to make two quarts of lemonade. How many scoops of powder lemonade mix are needed to make 3 gallons?
3 gallons = 12 quarts
if you need 3 scoops top make 2 quarts, then you will need (12/2) x 3 = 18 scoops of lemonade powder mix to make 3 gallons of lemonade.
Molly estimated the her car insurance was going to be $250 each month. It was actually going to be $230 each month. What is the percent error? *
Answer:
8.69%.
Step-by-step explanation:
Estimated value = $250
Actual value = $230
We need to find the percent error. It can be calculated as follows :
[tex]\%=\dfrac{|\text{estimated-actual}|}{\text{actual}}\times 100\\\\=\dfrac{250-230}{230}\times 100\\\\=8.69\%[/tex]
So, the percent error is 8.69%.
a rope of length 13 1/2 m has been divided into 9 pieces of the Same length what is the length of each pice
Answer:
When 13 1/2 into proper fraction it will be 27/2=13.5
Then divide 13.5 by 9
It becomes 1.5, so that means the ropes are 1.5 meters each
Step-by-step explanation:
I hope this helps, please give me brainliest
if we divide the 13.5 by 9 we will get the answer 1.5 and so we have 9 pieces of the length 1.5

Simplify
2(x+7) 2x + 20
- 2 =
x+4
2x + 8
Answer:
x = 0
Step-by-step explanation:
2(x+7) 2x + 20 - 2 = x+4(2x + 8) start by distributing
2(x+7) would be 2x+14
4(2x+8) would be 8x+32
2x+14 x 2x + 20 - 2 = x + 8x + 32 now combine like terms
2x and 2x can be combined on the left side
x and 8x can be combined on the right side
4x + 14 + 20 - 2 = x + 8x + 32
4x + 32 = 9x + 32 you can now solve this equation
start by subtracting 4x on both sides
32 = 5x +32 now subtract 32 on both sides
0 = 5x so x = 0
Answer:
x = 0
2(x+7) 2x + 20 - 2 = x+4(2x + 8) start by distributing
2(x+7) would be 2x+14
4(2x+8) would be 8x+32
2x+14 x 2x + 20 - 2 = x + 8x + 32 now combine like terms
2x and 2x can be combined on the left side
x and 8x can be combined on the right side
4x + 14 + 20 - 2 = x + 8x + 32
4x + 32 = 9x + 32 you can now solve this equation
start by subtracting 4x on both sides
32 = 5x +32 now subtract 32 on both sides
0 = 5x so x = 0

How can we use variables and equations to help us
solve problems?
Answer:
Variables help show the numbers and equation show the numbers
Step-by-step explanation:
Answer:
If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.

Answer:
y = - 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 5) and (x₂, y₂ ) = (2, - 3)
m = [tex]\frac{-3-5}{2+2}[/tex] = [tex]\frac{-8}{4}[/tex] = - 2
The line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = - 2x - 1 ← equation of line

What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
In the diagram below, ΔABC with sides of 13, 15, and 16, is mapped onto ΔDEF after a clockwise rotation of 90°.
The side AB is equal to DE. Then we have
DE = AB
2x - 1 = 16
2x = 16 + 1
2x = 17
x = 17/2
x = 8.5
The value of the variable 'x' will be 8.5. Then the correct option is D.
