When Charlotte installed a fence along the 200 foot perimeter of her rectangular backyard, she left an opening for a gate. In the diagram below, she used x to represent the length, in feet, of the gate. What is the value of x
Answers
Answer:
x = 10
Step-by-step explanation:
P = 2(60 + x) + 2(30) = 200
= 120 + 2x + 60 = 200
2x + 180 = 200
2x = 20
x = 10

Jonah and Graham are working together. Jonah claims that (x+y)^2 = x^2+y^2. Graham is sure Jonah is wrong, but he cannot figure out how to show it. a.) Help Graham find as many ways as poissible to convince Jonah that he is incorrect. How can he rewrite (x+y)^2 correctly?
Answers
Answer:
Here is what I got hope it helps!!!!!!!
Step-by-step explanation:
Equivalent expressions are expressions with the same value.
The proper way to rewrite the equation is: [tex]\mathbf{(x + y)^2 = x^2 + 2xy + y^2 }[/tex]
Jonah's equation is given as:
[tex]\mathbf{(x + y)^2 = x^2 + y^2}[/tex]
To convince Jonah that Jonah's equation is wrong, Graham can do any of the following
Assume values for x and yExpand the equationAssume value for x and y
Let x = 2 and y = 4
[tex]\mathbf{(2 + 4)^2 = 2^2 + 4^2}[/tex]
[tex]\mathbf{36 = 20}[/tex]
The above equation is false.
So, it means that: [tex]\mathbf{(x + y)^2 \ne x^2 + y^2}[/tex]
Expand the equation
We have:
[tex]\mathbf{(x + y)^2 = x^2 + y^2}[/tex]
Open the bracket
[tex]\mathbf{x^2 + 2xy + y^2 = x^2 + y^2}[/tex]
Cancel out common terms
[tex]\mathbf{2xy = 0}[/tex]
The above equation is false.
So, it means that: [tex]\mathbf{(x + y)^2 \ne x^2 + y^2}[/tex]
The proper way to rewrite the equation is:
[tex]\mathbf{(x + y)^2 = x^2 + 2xy + y^2 }[/tex]

3x + 4y = 36
y=-1/2x+8
Answers
Answer:
(x,y)=(4,6)
Step-by-step explanation:
3x+4y=36
y=-1/2 x+8
step 1: substitute the value of y
[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]
step 2: solve equation for x
[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]
3x-2x+32=36
x+32=36
x=36-32
x=4
step 3: substitute the value of x

The drop that rider's experience on Dr. Doom's Free Fall can be modeled by the quadratic function LaTeX: h\left(t\right)=-9.8t^2-5t+39h ( t ) = − 9.8 t 2 − 5 t + 39 where h is height in meters and t in time in seconds. What is the starting height of the riders?
Answers
Answer:
The starting height of the raiders is 39 meters.
Step-by-step explanation:
Physically speaking, a free fall motion is an uniformly accelerated motion due to gravity. Mathematically, speaking the equation of motion for the height of an object under free fall is a second order polynomial (quadratic function).
Let [tex]h(t) = -9.8\cdot t^{2}-5\cdot t + 39[/tex] be the height of the riders, in meters, the starting height is the height evaluated at [tex]t = 0\,s.[/tex] Hence, we proceed to the determined the required data by direct evaluation:
[tex]h(0) = -9.8\cdot (0)^{2}-5\cdot (0) +39[/tex]
[tex]h(0) = 39[/tex]
The starting height of the raiders is 39 meters above the ground.
Researchers in education are performing a study to see if listening to soothing music while taking a standardized math test increases the mean test score. The hypotheses are H 0 : mu=79 versus H a : mu>79 , and the p-value for the hypothesis test was 0.035.
At the 5 % significance level , what should the researchers conclude?
1. There is sufficient evidence to conclude that listening to soothing sounds increases the mean test score.
2. There is sufficient evidence to conclude that listening to soothing sounds decreases the mean test score.
3. There is insufficient evidence to conclude that listening to soothing sounds decreases the mean test score.
4. none of the above
Answers
Answer:
1. There is sufficient evidence to conclude that listening to soothing sounds increases the mean test score.
Step-by-step explanation:
A p - value less than 0.05 means that the test hypothesis is false or rejected.
In this question the test hypothesis is H 0 : mu=79 which is false as p-value is 0.035.
Whenever the p- value is less than the significance level H0 is rejected.
Hence the null hypothesis is rejected.
Therefore only choice 1 is correct.
There is sufficient evidence to conclude that listening to soothing sounds increases the mean test score.
There is sufficient evidence to support the claim.

Sara bought shoes for $39.95 and x pairs of socks for $1.99 each. Which expression shows the total money spent?
Answers
Answer:
$39.95 + $1.99x
Step-by-step explanation:
Cost of shoes = $39.95
Cost per pair of socks = $1.99
Number of socks pairs purchased = x
Total amout spent = (cost of shoes + cost of x pairs of socks)
Cost of x pairs of socks = $1.99 * x = $1.99x
Total amount spent = $39.95 + $1.99x
Answer:
$39.95 + $1.99x

A larger number is double the sum of 3 and a smaller number. The larger number is 2 less than 3 times the smaller number. If y represents the larger number and x represents the smaller number, which equations model the situation? Check all that apply.
Answers
Answer:
y = 3x - 2
3x - y = 2
y = 2(x + 3)
Step-by-step explanation:
y = the larger number
x = the smaller number
A larger number is double the sum of 3 and a smaller number
y = 2(x + 3)
y = 6 + 2x
The larger number is 2 less than 3 times the smaller number.
y = 3x - 2
Make -2 the subject
y - 3x = -2
Make 2 the subject
y = 3x - 2
y - 3x = -2
(y - 3x) * -1 = -2 * -1
-y + 3x = 2
3x - y = 2
The answers:
y = 3x - 2
3x - y = 2
y = 2(x + 3)

A bakery buys a large bag of sugar that has 34 cups. They use 10 cups to make some cookies. They use the rest of the bag to make 144 giant muffins. Their customers want to know how much sugar is in each muffin.
Answers
Answer:
there would be 1 ÷ 6 sugar in each month
Step-by-step explanation:
The computation of the customers that want to know the sugar in each muffin is shown below
Here we assume the sugar in each muffin be x
Now there is 30 cups and 10 cups should be used for making some cookies
And, the rest would be use for making 144 gaint muffins
So, the equation that should be used is
10 + 144x = 34
144x = 24
x = 1 ÷ 6
So there would be 1 ÷ 6 sugar in each month
