Answer:
See answers below
Step-by-step explanation:
Perimeter of a square = 4L
L sis the side length of the square
L = 5x^4y^2
perimeter = 4(5x^4y^2)
perimeter = 20x^4y^2
2) Length = 6x-10
Width = 4x+3
Area of rectangle = Length * Width
Area of rectangle = (6x-10)(4x+3)
Area of rectangle = 24x^2+18x-40x-30
Area of rectangle= 24x^2-22x-30
perimeter = 2(L+W)
perimeter 2(6x-10+4x+3)
perimeter = 2(10x-7)
perimeter = 20x-14
Hence the perimeter of the rectangle is 20x-14
In a recent survey, 15 skydivers said that they have never had a skydiving accident. This was 60% of the total number of skydivers that were surveyed. What was the total number of skydivers surveyed?
Answer:
total sky divers is 25
Step-by-step explanation:
60% = 15 skydivers
divide by 6 both sides
10% = 2.5
times by 4 both sides
40%=10
_________
60%+40%=100%
15+10=25

Answer:
A) 3x +10y = 36
Step-by-step explanation:
The graph tells us the x-intercept is 12. The x-intercept is the value of x when y = 0. For some equation coefficients ax+by=36, the x-intercept is ...
x-intercept = 36/a
Then the coefficient 'a' is ...
a = 36/(x-intercept) = 36/12 = 3
Only one answer choice has an x-coefficient of 3 -- the correct one.
3x +10y = 36

A study conducted to measure the academic performance and attention span of teenagers reported that the mean time to distraction for 80 teenage boys working on an independent task was 6.2 min in the study with a sample standard deviation of 2.1 minutes. Is there convincing evidence that the average attention span for teenage boys is more than 5 minutes
Answer:
we can conclude that there is significant evidence that there is convincing evidence that the average attention span for teenage boys is more than 5 minutes
Step-by-step explanation:
H0 : μ ≤ 5
H1 : μ > 5
Sample mean, xbar = 6.2
Sample Standard deviation, s = 2.1
Sample size, n = 80
The test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(6.2 - 5) ÷ (2.1 / sqrt(80))
1.2 ÷ 0.2347871
Test statistic = 5.1110133
Testing with α = 0.05
Using Pvalue from a test score calculator :
Pvalue = < 0.00001
0.00001 < 0.05
Since,
Pvalue < α ; We reject H0
Hence, we can conclude that there is significant evidence that there is convincing evidence that the average attention span for teenage boys is more than 5 minutes.

Draw the line of reflection that reflects △ABC onto triangle Δ A'B'C'
The line for the graph x=1 is the line of reflection that reflects triangle ABC onto triangle A'B'C'.
You have to find the middle points between each pair of identical points and then join them.
The solution is, x = 1 will be the line of reflection.
What is reflection?In mathematics, a reflection (also spelled reflexion) is a mapping from a Euclidean space to itself that is an isometry with a hyper plane as a set of fixed.
here, we have,
from the given information , we get,
Coordinates of the vertex A → (-4, -6)
Coordinates of the vertex A' → (6, 6)
Since, y-coordinates are same opposite in notation,
Therefore, by the rule of reflection, line of reflection will be a line parallel to y-axis.
And points A and A' will be equidistant from the line of reflection.
Midpoint between A and A' = (x1+x2/2) , (y1+y2/2)
= (-4+6 / 2 , -6+6 /2)
= (1, 0)
Therefore, x = 1 will be the line of reflection.

the sector's area = 530.66/4 = 132.67 ft^2
how many 1/3 inch cubes does it take to fill a box with width 2 2/3 inches length 3 1/3 inches and height 2 1/3 inches
Answer:
560/9 or around 63 cubes
Step-by-step explanation:
2 2/3 -> 8/3
3 1/3 -> 10/3
2 1/3-> 7/3
7/3 x 8/3= 56/9
56/9 x 10/3 = 560/27
560/27 divided by 1/3
= 560/9

Carlos bikes 2 1/2 miles in 1/4 hours. At that rate, find the number of miles he would bike in 1 hour.
A. 5/8 miles
B. 2 3/4 miles
C. 5 miles

Answer: 10
Step-by-step explanation:
2.5 times 4
Solve for a.

• You order 4 chicken sandwiches and a hamburger. The cost of a hamburger is $2.50 and the total bill is $14.30. Find the cost of a chicken sandwich
part 1 of the word problem
Verbal Model:
part 2 of the word problem
Algebraic Equation:
please with all equations show your work.
Step-by-step explanation:
for the first one multiply the equation by 5
5(-10)=5(1/5)a
-50=a
2. 3(n-8)=-12
divide the equation by 3
(3(n-8))/3=-12/3
(n-8)=-4
add 8 to both sides
n-8+8=-4+8
n=4
3. 8+4x=-16
subtract the whole equation by 8
-8+4x=-16-8
4x=-24
divide the equation by 4
4x/4=-24/4
x=-6
4. 4 chicken sandwiches at $2.50 each, to find the value of all the values for all 4 sandwiches is 4(2.50)=10
and since there is only one hamburger you just need to find the value for the one burger which is x.
4(2.50)+1(x)=14.30
10+x=14.30
subtract the equation by 10
10-10+x=14.30-10
x=4.30
Hope this helps :)

Please find the square roots of the following complex number.
[tex]z = 81(\cos(\frac{4\pi}{9})+i\sin(\frac{4\pi}{9}))[/tex]
Hey there,
First, find the square root of the given equation.
[tex]\sqrt{z}=\sqrt{81(\text{cos}(\frac{4\pi}{9})+i\text{sin}(\frac{4\pi}{9})}\\=9\text{cos}\frac{1}{2}(2k\pi+(\frac{4\pi}{9}))+i\text{sin}\frac{1}{2} (2k\pi+(\frac{4\pi}{9}))[/tex]
Keep in mind that this is solved for k = 0 and 1.
Second, simplify.
[tex]=9\text{cos}(\frac{2\pi}{9})+i\text{sin}(\frac{2\pi}{9})~\text{or}~9\text{cos}(\frac{11\pi}{9})+i\text{sin}(\frac{11\pi}{9})[/tex]
Best of Luck!

Solve the equation for x: 126 = 3x.
A. x = 378
B. x = 129
C. x = 123
D. x = 42
Answer:
The answer is answer D, x=42.
Step-by-step explanation:
To isolate the variable, you need to divide both sides of the equation by three, using the division property of equality. 126/3=42 , and 3x/3=x , this gives you 42=x, or x=42, meaning the answer is D.
Given that triangle ABC ~ XYZ, AB= 4,XY=3,and XZ= 5, find AC
Answer:
[tex]AC = \frac{20}{3}[/tex]
Step-by-step explanation:
Given
[tex]AB = 4[/tex]
[tex]XY = 3[/tex]
[tex]XZ = 5[/tex]
Required
Find AC
ABC XYZ
To solve AC, we make use of the following equivalent ratios.
[tex]AB : AC = XY : XZ[/tex]
This gives:
[tex]4 : AC = 3 : 5[/tex]
Express as fraction
[tex]\frac{4 }{ AC }= \frac{3 }{ 5}[/tex]
Cross multiply
[tex]3 * AC = 4 * 5[/tex]
[tex]3 * AC = 20[/tex]
Solve for AC
[tex]AC = \frac{20}{3}[/tex]

"Solve the following system of equations."
-5x+3y=22
-6x+7y=23
I have to figure out x and y
Answer:
x = - 5, y = - 1
Step-by-step explanation:
Given the 2 equations
- 5x + 3y = 22 → (1)
- 6x + 7y = 23 → (2)
Multiplying (1) by - 6 and (2) by 5 , then adding will eliminate the x- term
30x - 18y = - 132 → (3)
- 30x + 35y = 115 → (4)
Add (3) and (4) term by term to eliminate x
0 + 17y = - 17
17y = - 17 ( divide both sides by 17 )
y = - 1
Substitute y = - 1 into either of the 2 equations and solve for x
Substituting into (1)
- 5x + 3(- 1) = 22
- 5x - 3 = 22 ( add 3 to both sides )
- 5x = 25 ( divide both sides by - 5 )
x = - 5
llyssa spent 3/8 of her money on a bag. she gave 2/5 of the remaining amount to her sister. What fraction of her money was left with?
Answer:
3/8
Step-by-step explanation:
After spending 3/8 of her money on a bag, she has 5/8 of the original amount of money left. As she gave 2/5 of the remaining amount of money to her sister, she gave 1/4 of the original amount of money to her sister (5/8 × 2/5 = 1/4). Therefore, there's only 3/8 (1 - 3/8 - 1/4 = 3/8) of the original amount of money left in her bag.
