Five congruent squares are put together without gaps or overlap to form a figure shaped like a plus sign. The
perimeter of the figure is 72 cm. Find the area of the figure, in cm?
Answer:
180 square centimeters
Step-by-step explanation:
Because the five squares are congruent, the 12 sides of the figure are all equal in length. Then the length of one side is 72/12 = 6 cm. Therefore, the area of each square is 36 sq cm and the area of the figure, 5 x 36, is 180 sq cm.

Answer:
C.) -3/2
Step-by-step explanation:
To find the slope you need to use the formula: m = y2 - y1/x2 - x1
Point: (-2,1) and (2,-5)
m = y2 - y1/x2 - x1
m = -5 - 1/2 - (-2)
m = -6/2 + 2
m = -6/4
m = -3/2
The value of a new car decreases by about 15% in the first year. How much will a car be worth after one year if its initial value was x dollars?
Answer:
The value of the car will be x - (0.15)x after a year.
Step-by-step explanation:
The car was 15% more when it first came out, and the price went down by 15% after a year.
Therefore, to solve this problem, we need to multiply 0.15 by the initial cost, which will tell you how much the car price decreased.
Then, we need to subtract this amount from x, or the initial cost, in order to find how much the car will be worth after a year.
Therefore, the value of the car will be x - (0.15)x after a year.
Hope this helps! :D

i need to find the points for a graph asap by finding the asymptote!!!
Answer:
y=0
Step-by-step explanation:
Exponential functions, always have a horizontal asymptote. A function of the form f(x) = a (b^x) + c always has a horizontal asymptote at y = c. In this case the function is
[tex]y=3^{x+2} \\\\We\ can\ rewrite\ it\ like\\\\\y=3^x.3^2\\y=9(3^x)[/tex]
so it doesn't have a +c which means the horizontal asymptote is y = c = 0
y = 0 is the horizontal asymptote

what is the measure of
Answer:
x=12
Step-by-step explanation:
Im not sure which measure you're talking about, but I'll show you what I did here:
A triangle = 180 degrees.
4x + 8x + 4x =16x
-8 - 1 - 3 = -12
180 = 16x - 12 -Add 12 to both sides
192 = 16x -divide by 16 to get x by itself
12 = x
Angle A = 88 degrees (8 times 12 then subtract 8)
Angle B = 47 degrees (4 times 12 then subtract 1)
Angle C = 45 degrees (4 times 12 then subtract 3)

To get a perfect square you must divide the bx or 6x in this situation then square it.
6/2 = 3
3^2 = 9
b.) (x - 1)(x - 5)
x^2 - 6x + 9 = -5 + 9
x^2 - 6x + 9 = 4
x^2 - 6x + 9 - 4 = 4 - 4
x^2 - 6x + 5 = 0
(x - 1)(x - 5)
x - 1 = 0
x = 1
x - 5 = 0
x = 5

Answer:
What’s is the answer o need heelpp
Step-by-step explanation:
Recommended number of flowers for a garden of 24 square feet is 32 so option (D) will be correct.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
In another word, a linear function is a function that varies linearly with respect to the changing variable.
Given data is forming a linear function.
Since the slope of a linear function is always constant
Slope = difference in y's coordinate / difference in x's coordinate
Lets say Garden area is x and the number of flowers is y
Then,
Slope = (y - 20)/(24-15) = (20-16)/(15-12)
(y - 20)/9 = 4/3
y = 12 + 20 = 32
Hence " Recommended number of flowers for a garden of 24 square feet is 32".

Answer:
y = 7x + 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 )
Here m = 7 and (0, 1 ) ← crosses y- axis ⇒ c = 1
y = 7x + 1 ← equation of line

2. Ashley had a summer lemonade stand where she sold small cups of lemonade for $1.25 and large
cups for $2.50. If Ashley sold a total of 155 cups of lemonade for $265, how many cups of each
type did she sell?
Answer:
[tex]\boxed {\boxed {\sf 98 \ Small \ Cups}}\\\\\boxed {\boxed {\sf 57 \ Large \ Cups}}[/tex]
Step-by-step explanation:
Let's make a system of equations.
First, define the variables.
Let s= small cups and g= large cups
Next, make 2 equations. 1 for the money and 1 for the number of cups.
Money
A small cup costs 1.25 and a large cup costs 2.50. The total money made is 265. 1.25s+2.50g=265Number
A total of 155 cups of lemonade were sold. The sum of small cups and large cups sold will equal 155. s+g=155Here is our system of equations:
[tex]1.25s+2.50g=265 \\s+g=155[/tex]
Now, solve. Let's isolate a variable in the 2nd equation, so we can plug it in after.
Subtract g from both sides of the equation. s+g=155 s+g-g=155-gs=155-gNow we know that s is equal to 155-g. We can substitute (155-g) in for s in the first equation.
[tex]1.25s +2.50g=265[/tex]
[tex]1.25(155-g)+2.50g=265[/tex]
Distribute the 1.25
1.25(155-g)= (1.25*155)+ (1.25*-g)= 193.75-1.25g[tex]193.75-1.25g+2.50g=265[/tex]
Work to isolate the variable. Subtract 193.75 from both sides of the equation and combine like terms on the left.
[tex]193.75-1.25g+2.50g=265-193.75[/tex] (Subtract 193.75)
[tex]-1.25g+2.50g=265-193.75[/tex]
[tex]1.25g=71.25[/tex] (Combine like terms).
1.25 and g are being multiplied. The inverse of multiplication is division. Divide both sides by 1.25
[tex]1.25g/1.25=71.25/1.25\\g=71.25/1.25\\g=57[/tex]
Now we know that 57 large cups were sold. Plug 57 back into the original second equation to find the small cups.
[tex]s+g=155[/tex]
[tex]s+57=155[/tex]
Subtract 57 from both sides of the equation to isolate the variable, s.
[tex]s+57-57=155-57\\s=155-57\\s=98[/tex]
Ashley sold 57 large cups and 98 small cups.
small cup she sold = x = 98
large cup she sold = y =57
Solve for s.
72=27+9s
How do you solve for s?
Answer:
s=5
Step-by-step explanation:
Answer:
S = 5
Step-by-step explanation:
Subtract 27 from both sides
45 = 9s
divide by 9
s = 5
Look at this angle, what are the sides?
Answer:
Both of the arrowed ones are the sides

Solve for s.
12s=72
s = 17
s = 27
s = 3
s = 7
Answer: s = 6
Step-by-step explanation:
just simply divide both sides.
12s / 12 = 72 / 12
s = 6
A shoe store is having a clearance sale on their summer shoes. All summer shoes are marked 55% off. A sign states you can take an additional 10% off the clearance sale prices. Kelly is deciding between two pairs of sandals shown in the table.
Shoes Original Price
Blue Sandals $75
Tan Sandals $68
If she buys the blue sandals, what is the final price Kelly will pay? Round to the nearest cent.
Answer:
$30.38
Step-by-step explanation:
Final Price = Original Price - Discount
Final Price = 75 - 41.25
Final Price = $33.75
Then its the additional 10%
So now you make your original cost $33.75 to make it easier so
Final Price = Original Price - Discount
Final Price = 33.75 - 3.375
Final Price = $30.38
Final Answer: $30.38
The final price Kelly will pay round to the nearest cent is $30 38¢
What is percent?In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".
Now it is given that,
Discount = 55%
Additional discount = 10%
Original Price of Blue Sandals = $75
Original Price of Tan Sandals = $68
Since Kelly bought blue sandels,
So, discount on Blue Sandals = 55% of $75
⇒ discount on Blue Sandals = 0.55 * $75 = $41.25
So, Cost of Blue Sandals = $75 - $41.25
⇒ Cost of Blue Sandals = $33.75
Now there is additional discount of 10%
Additional discount = 10% of $33.75
⇒ Additional discount = 0.10% * $33.75
⇒ Additional discount = $3.375
Thus, Final Cost of Blue Sandals = $33.75 - $3.375
⇒ Final Cost of Blue Sandals = $30.375
Round to the nearest cent final cost of Blue Sandals = $30 38¢
Thus, the final price Kelly will pay round to the nearest cent is $30 38¢
