To meet the goal of $320.00 for the playground, they need to raise a total of $400.00
How much they need to raise?
We know that for each $20 raised, they get $16 for the playground. They need to get $320.00 for the playground.
Taking the quotient:
N = $320.00/$16 = 20
This means that they need to raise $20 20 times, so they get $16 20 times which is equal to $320.
Then, we can conclude that they need to raise a total of:
$20*20 = $4,000

In a quadrilateral OABC, D is the midpoint of BC and E is the point on AD such that AE : ED=2: 1. Given that OA = a, OB = b and OC = c, express OD and OE in terms of a, b and c.
Answer:
Step-by-step explanation:
CB=OB-OC;
CD=CB/2=(OB-OC)/2=(b-c)/2;
OD=OC+CD=c+(b-c)/2=c/2+b/2;
AD=OD-OA=c/2+b/2-a;
AE=2/3*AD=2/3*(c/2+b/2-a)=c/3+b/3-2*a/3;
OE=OA+AE=a+c/3+b/3-2*a/3=a/3+b/3+c/3;
-------------------------------------------------------------------------------------------------
OD=c/2+b/2;
OE=a/3+b/3+c/3;
The value of OE = (a+ b+ c)/3 and OD = (b + c)/2.
In quadrilateral OABC, we are given that D is the midpoint of BC,
and E is a point on AD such that AE : ED = 2 : 1.
Also, OA = a, OB = b and OC = c
Now, By the Midpoint Theorem, we also have
OD = (1/2)OB + (1/2)OC.
OD = (1/2)(OB + OC)
OD = (1/2)(b + c)
OD = (b + c)/2.
and, CD= (OB- OC)/2 = (b-c)/2
Now, AD=OD-OA= (c+b)/2 - a
and, AE=2/3 x AD
= 2/3 x (c+ b)/2 - a
= (c + b - 2a)/3
Then, OE = OA + AE
= a + (c + b - 2a)/3
= (a+ b+ c)/3

A line passes through the point (−4,5) and has a slope of −6.
Write an equation in slope-intercept form for this line.
Answer:
y = -6x - 19
Step-by-step explanation:
We can use y = m x + c to find the equation of the line.
Here,
m ⇒ slope
c ⇒ y - intercept
They have already given the slope of the line.
m = -6
And now we have to find the y - intercept using the given coordinates.
( -4 , 5 ) ⇒ ( x , y )
Let us find now.
y = m x + c
5 = -6 × -4 + c
5 = 24 + c
5 - 24 = c
-19 = c
Now let us write the equation of the line.
y = m x + c
y = -6x - 19
Each equation below is followed by several stories.
Select all of the stories that can be represented by the equation.
If none of the stories can be represented, select "None of the above".
(a)x+11=44
Typically, there are keywords in the story that tell us what operations we need to use.
For instance, in terms of age:
"Younger" or "older" connotes to subtraction from the age of the older person. It can also connote to the addition to the age of the younger person."Years ago" typically connotes to the subtraction of x years from the person's current age."More years" typically connotes to the addition of x years to the person's current age.Solving the QuestionLet's take a look at our first option.
Yousif is x years old. Rana is 44 years older than Yousif. Rana is 11 years old.Firstly, this option doesn't even make sense. How can Rana be 11 years old but also 44 years older than Yousif?
Let's look at our second option.
Rana is x years old. in 11 more years, she will be 44 years old.Immediately, we see "11 more years". This means that we will be adding 11 to Rana's current age, which is x:
[tex]x+11[/tex]
This expression above is equal to 44, since the question tells us that Rana will be 44 years old in 11 years:
[tex]x+11=44[/tex]
This is our final expression. It is the same as the given expression in the question.
AnswerRana is x years old. in 11 more years, she will be 44 years old.
Shoes sold at the Shoe Express are discounted 25% off the original price. If a pair of shoes originally cost $46, calculate the sale price of the shoes
Answer:
$34.50
Step-by-step explanation:
$46*.25 = $11.50
$46 - 11.50 = $34.50
Solution:
We know that:
Discounted price: Original price - (Original price × Discount)Original cost of a pair of shoes: $46Discount: 25%This means that:
Sale price of a pair of shoes: 46 - (46 × 25%)Step-1: Convert "25%" into a fraction.
25% = 25/100 = 1/4Step-2: Find the discounted price.
Sale price of a pair of shoes: 46 - (46 × 1/4)Sale price of a pair of shoes: 46 - (23/2)Sale price of a pair of shoes: 46 - 11.5Sale price of a pair of shoes: $34.5An electric utility worker wants to anchor a guy wire from the top of a 13.2-foot utility pole to a spot that is 5.5 feet from the base of the pole on level ground.

Please remember that an arithmetic sequence is a sequence where we use either addition or subtraction to get to the next term.
Now, let's find an arithmetic sequence here.
Is it Option A?
Remember: It should have a common difference of 2.
Which means we either add or subtract 2 to get to the next term.
Well, it seems like Option A is right.
Let's check the other options.
Is Option B right? Nope.
Here's why.
Hint: Pay attention to the signs.
We have
1, -3, 5, -7, 9...
So Option B is wrong.
Option C is correct, because we subtract 2 each time.
Option D is wrong, because we multiply by 2 each time.

Consider the line x-7y=1
What is the slope of a line perpendicular to this line?
What is the slope of a line parallel to this line?
Answer:
Perpendicular slope: -7x
Parallel slope: 1/7x
Step-by-step explanation:
Rewrite this into slope-intercept form. So y=1/7x -1/7
Slope of a perpendicular line is the reciprocal of the original slope. So perpendicular line would be y=(-7)x-1/7. Slope in the perpendicular is -7. A parallel line will have the same slope,so basically y=1/7x-1 .
It doesn't matter what the y-int would be since a perpendicular/parallel slope only depends on the slope itself.
Answer:
[tex]\displaystyle \parallel\:\frac{1}{7} \\ \perp\:-7[/tex]
Step-by-step explanation:
[tex]\displaystyle x - 7y = 1 \hookrightarrow \frac{-7y}{-7} = \frac{-x + 1}{-7} \\ \\ \boxed{y = \frac{1}{7}x - \frac{1}{7}}[/tex]
