. The perimeter of a square is 8y – 12. The area of the square is 100 square units. What is the value of y?
Answer:
y = 6.5 units
Step-by-step explanation:
Let L be the length of sides of the square.
Given the following data;
Perimeter of square = 8y - 12
Area of square = 100 square units
To find the value of y;
Area of a square = L²
Substituting into the formula, we have;
100 = L²
L = √100
L = 10 units
Mathematically, the perimeter of a square is given by the formula;
Perimeter of a square = 4L
Substituting into the formula, we have;
8y - 12 = 4*10
8y - 12 = 40
8y = 40 + 12
8y = 52
y = 52/8
y = 6.5 units
At the mall, Jamie buys a pair of jeans for $34 and then a shirt for $12. The store is having a 25%
off sale. You will then have to pay 8% sales tax. What is the total amount you will pay?
Answer:
$37.26
Explanation:
firstly, we find the total original price: $34 + $12 = $46.
next, we can multiply this by 100% - 25% = 75% to find the discounted price:
$46 × 75%
= $46 ÷ 100 × 75
= $34.50
finally, add on the sales tax which is 100% + 8% = 108%:
$34.50 × 108%
= $34.50 ÷ 100 × 108
= $37.26

so i am hqving trouble with a particular question and hoping somebody could help me with it. this is the particular question 47 + 10x = -10x + 7
Step-by-step explanation:
given 47 + 10x = -10x + 7
[tex]47 + 10x = - 10x + 7 \\ 47 + 10x + 10x = 7 \\ 47 + 20x = 7 \\ 20x = 7 - 47 \\ 20x = - 40 \\ x = - 40 \div 20 \\ = - 2[/tex]

The height of a batted baseball is modeled by the equation h(t) = -16t²+64t+6, where t is measured in seconds and h is measured in feet.
a.) At what time in seconds does the ball attain its maximum height?
b.) What is the maximum height attained by the ball? (Give your answer in feet.)
Answer:
[tex] \frac{dh}{dt} = - 32t + 64 = 0 \\a) \: t = \frac{ - 64}{ - 32} = 2 \\ \\ b = - 16 \times 4 + 64 \times 2 + 6 = - 64 + 2 \times 64 + 6 = 64 + 6 = 70[/tex]
Answer:
a) t = 2 seconds
b) 70 feet
Step-by-step explanation:
First of all, we are going to take the derivative of the function (which is a displacement function) to make find its velocity function.
[tex]h(t) = -16t^{2} +64t+6[/tex]
To find the derivative of the equation, we must multiply the coefficient by the exponent and then minus one from the exponent for each term.
[tex]v(t)=(-16)(2)t^{2-1} +64(1)t^{1-1}+6(0)t^{0-1} \\v(t) = -32t +64[/tex]
Now we can substitute in v=0
This is because the ball is at the top of its parabola path, it is the turning point and the slope is 0. The velocity physically speaking would also be 0 at the very top of its path.
[tex]0=-32t+64[/tex]
Rearrange and we get:
[tex]32t = 64\\t=2[/tex]
Ball attains maximum height at 2 seconds.
To find the maximum height, we now just have to substitute back in the time into the original equation to find the height.
[tex]h(t) = -16t^{2} +64t+6[/tex]
[tex]h(2) = -16(2)^{2} +64(2)+6\\h(2)=-64+128+6\\h(2) = 70[/tex]
The maximum height attained is 70 feet.
Hope this helped!

Triangle JKL is an equilateral triangle with two of its vertices at points J and K. What are the coordinates of point L? Round to the nearest tenth as needed.
Answer:
The X coordinate is 6, since it's midway between J and K. If you draw a midline from L, and running to the midpoint of the line JK, you make two right angled triangle. The length of the midline would be the square root of the difference of the squares of six and three, which is 5.20, which is the offset of the Y coordinate of L from the Y coordinate of J and K, which is 2. Add 5.20 to 2 to get the Y coordinate of L as 7.20. L is therefore (6,7.20)
Answer:
(6, 7.2)
Step-by-step explanation:
Since it is an equilateral triangle, all of the side length must be equal.
Therefore, we know the lengths JK = 6 and JL = 6. If h is the height of the triangle, the Pythagoras's theorem says
(JK/2)² + h² = JL²
putting in the values of JK and JL gives
(6/2)² + h² = 6²
3² + h² = 6²
subtracting 3^2 from both sides gives
h² = 6² - 3²
h² = 27
Taking the square root of both sides gives
h =
[tex] \sqrt[3]{3} [/tex]
h = 5.2
With the value of h in hand, we can now read off the coordinates of L.
The x coordinates of L is 6 (count the boxes along the x-axis until you are under L or halfway between J and K).
The y-coordinates of L is 2 + h = 2 + 5.2 = 7.2 ( how far above the x-axis the triangle is plus the height of the triangle).

Distributive property , multiply (5-2x) by 4:
20 -8 x + 3 = 7
Combine like terms:
23 - 8x = 7
Inverse add and subtract:
23 - 7 - 8x + 8x = 7 - 7 + 8x
16 = 8x
Inverse divide:
16/8 = 8x/8
x = 2

Mark wants to paint a mural. He has 1 1/8 gallons of yellow paint, 1 1/9 gallons of green paint, and 7/8 gallons of blue paint. Mark plans to use 3/4 a gallon of each paint color. How many gallons of paint will he have left after painting the mural? Enter your answer as a simplified fraction.
Answer:
We have 31/36 gallons of paint left after painting the mural.
Step-by-step explanation:
"Mark wants to paint a mural. He has 1 1/8 gallons of yellow paint, 1 1/9 gallons of green paint, and 7/8 gallons of blue paint. Mark plans to use 3/4 a gallon of each paint color. How many gallons of paint will he have left after painting the mural? Enter your answer as a simplified fraction."
==================================================================
First change each number into a improper fraction:
1 1/8 = 9/8
1 1/9 = 10/9
7/8 = 7/8
=================================================================
"If Mark has 9/8 gallons of yellow paint, and he uses 3/4 gallons"
-We have to multiply 3/4 by 2/2 to make the denominators same.
3/4 × 2/2 = 6/8
Now subtract 6/8 from 9/8.
9/8 - 6/8 = 3/8
We will have 3/8 gallons of yellow paint.
==================================================================
"If Mark uses 10/9 gallons of green paint, and he uses 3/4 gallons"
- We have to multiply 10/9 by 4/4, and 3/4 by 9/9, to get a common denominator.
10/9 × 4/4 = 40/36
3/4 × 9/9 = 27/36
Now subtract 27/36 from 40/36
40/36 - 27/36 = 13/36
We will have 13/36 gallons of green paint.
==================================================================
"If Mark uses 7/8 gallons of blue paint, and he uses 3/4 gallons"
-We have to multiply 3/4 by 2/2 to get a common denominator.
3/4 × 2/2 = 6/8
Now subtract 6/8 from 7/8.
7/8 - 6/8 = 1/8
We will have 1/8 gallons of yellow paint.
==================================================================
Now, we will add the leftover amounts of paint to find the answer.
3/8 + 13/36 + 1/8
Add "like terms".
4/8 + 13/36
Simplify 4/8 into 1/2
1/2 + 13/ 36
Multiply 1/2 by 18/18 to get a common denominator.
1/2 × 18/18 = 18/36
Substitute 18/36 as 1/2 in the expression.
18/36 + 13/36 = 31/36
So, We have 31/36 gallons of paint left after painting the mural.
==================================================================

Two angles have a supplementary relationship. The measure of one angle is 14°. What is the measure of the second angle?
Answer:
166°
Step-by-step explanation:
Supplementary angles have a sum of 180 degrees
That being said, we can find the measure of the missing angle by subtracting the measure of the given angle by 180
(the giving angle having a measure of 14°)
so missing angle = 180 - 14
180 - 14 = 166
Hence, the measure of the second angle 166°

104+76=180 and a circle is 360
- Thx for the points have a nice day! ^ω^
Answer:
A. 76
B. 256
Step-by-step explanation:
DF is a diameter so that means the right side of the
circle measure 180 degrees. Angle DGE measures 104, since that the central angle that means Arc DE measures 104 also.
Using arc addition, part of the right side measure 104 so that means the remaining arc must add up to 180.
[tex]104 + x = 180[/tex]
[tex]x = 76[/tex]
Arc EF measure 76.
2. A circle has 360 degrees in it. We are asked to find the measure of the circle expect the Arc ED.
Arc ED measures 104 so
[tex]360 - 104 = 256[/tex]
1000 chicken wings weighs 3000 g how many grams in one chicken wing weigh
Answer:
3 grams are in one chicken wing
Step-by-step explanation:
Set up an equation:
Variable x = grams per 1 chicken wing
1000/3000 = 1/x
Cross multiply
1000 × x = 3000 × 1
1000x = 3000
Divide both sides by 1000 to isolate the variable x
x = 3
Answer:
3
Step-by-step explanation:
