A sporting goods store sells square exercise mats that are 17 m on a side. Find the perimeter and area of the mat.
Answer:
Permeter= 68m
Area= 289m^2
Step-by-step explanation:
Perimeter = 17^4 = 68m cause perimeter is the total length and square has 4 sides
Area= 17 ^17= 289m^2
Area of square is to multiply length x length
The perimeter and area of the mat will be 68 meters and 289 square meters.
What is the area and perimeter of the square?All the sides of a square are congruent. Let a be the side length of the square. Then the area of the square is the square of the side length of the square.
The area of the square will be
A = a² square units
The sum of all the sides of the square will be known as the perimeter of the square.
The perimeter of the square will be
P = 4a units
A sporting goods store sells square exercise mats that are 17 m on a side.

You have Pennies and nickles that are equal to $8.80. You have twice the number of nickles than Pennies. Write an equation for this problem. How many nickles do you have and how many Pennies do you have?
Answer:
Step-by-step explanation:
Let's set up the variables as nickel=n and penny=p, for how many coins he has of each type. What we know is that Calvin had $8.80 total and that he has twice as many nickels as pennies. So, one equation for his total money and another for how many separate coins: 8.80 = 0.01p + 0.05n 2p=n

Yolanda makes $11.25 per hour at her part-time job. During one week, she worked 1225 hours and also earned some tips. Her final pay for the week was $159.50.
How much money did Yolanda earn in tips?
Answer:
she earned $20 in tips
Step-by-step explanation:
- figure out how much she'll get payed in 12 hours of work, :
12 x $11.25 = $135 for 12 hours work, then find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:
2/5 of $11.25 = $4.50, after all of that, add up both of these sums together to get her total pay for hours worked:
$135 + $4.50 = $139.50
now you need to subtract that sum from her total pay to find out how much money she earned in tips:
$159.50 - $139.50 = $20, so basically thats how i got 20.

At what ordered pair is "Parking Lot B" located at?
The ordered pair of the parking lot is the coordinates of the lot in the coordinate plane
Parking lot B is located in the ordered pair (-3,4)
How to determine the ordered pair of lot BFrom the figure, we have the following highlights
Parking lot B is located at x = -3 on the horizontal axis, and it is located at y = 4 on the vertical axis.
So, we have:
(x,y) = (-3,4)
Hence, parking lot B is located in the ordered pair (-3,4)

State and show what additional information is required in order to know that the triangles are
congruent for the given reason.
SAS
Answer:
Step-by-step explanation:
We already know that both triangles have a congruent side length.
We also know angle KVM or UVW are the same
We only have to know if VM and WV are the same.
This way, each triangle will have two congruent side lengths and a angle. The third side will therefore be the same.
By the same logic, if we know that KM and UW are the same, the two triangles are also congruent.
To determine if two triangles are congruent using the SAS (Side-Angle-Side) criterion, we need additional information about the length of one side, the measure of one angle, and the length of another side in both triangles.
This information is crucial in order to establish the congruence between the triangles. For example, let's consider two triangles, triangle ABC and triangle DEF. To prove that these triangles are congruent using the SAS criterion, we need to know: 1. The length of side AB in triangle ABC and the length of side DE in triangle DEF. 2. The measure of angle A in triangle ABC and the measure of angle D in triangle DEF. 3. The length of side BC in triangle ABC and the length of side EF in triangle DEF. By knowing these measurements, we can compare the corresponding sides and angles of the two triangles. If the lengths of the corresponding sides are equal and the measures of the corresponding angles are equal, then we can conclude that the two triangles are congruent by the SAS criterion.

Answer:
length = 50 cm
Step-by-step explanation:
let width be w then length = w + 10
area = w(w + 10) = 2000 , that is
w² + 10w = 2000 ( subtract 2000 from both sides )
w² + 10w - 2000 = 0 ← in standard form
Consider the factors of the constant term (- 2000 ) which sum to give the coefficient of the w- term ( + 10)
the factors are + 50 and - 40 , since
50 × - 40 = - 2000 and sum = 50 - 40 = + 10
(w + 50)(w - 40) = 0 ← in factored form
equate each factor to zero and solve for w
w + 50 = 0 ⇒ w = - 50
w - 40 = 0 ⇒ w = 40
Since w > 0 then w = 40 and
length = w + 10 = 40 + 10 = 50 cm

Answer:
0.65
Step-by-step explanation:
Since we have given that
Cost of 8 pencils = 5.20
We need to find the cost of 1 pencil.
For this we'll use the unitary method,

use the zero and the labeled point to write the quadratic function represented by the graph.
A.y=x^2-2x-8
B. y=2x^2-12x+16
C. y=x^2+2x-8
D. y=2x^2+4x-16
Answer:
A. x² - 2x - 8
Step-by-step explanation:
At x = -2, 4 graph cut x- axis. So, they are zeroes of f(x).
So, f(x) = k(x+2)(x-4), where k is a constant.
Now, (3, -5) in f(x), we get
-5 = k (3+2)( 3 -4)
-5 = -5k
k= 1
So, f(x) = (x+2)(x-4)
= x² - 2x - 8
So, option A is right.
In the year 2003, a company made $6.5 million in profit. For each consecutive year after that, their profit increased by 8%. How much would the company's profit be in the year 2007, to the nearest tenth of a million dollars?
Answer:
$8,580,000 (rounded) = $9,000,000
Step-by-step explanation:
Keep in mind, 2007 is four years after 2003.
So, 8(%) • 4 = 32(%)
Over the course of 4 years, the companies profits increased by a total of 32 percent.
(*Write 6.5m in standard form)
6,500,000 + 32% = $8,580,000
8,580,000 (rounded up) = 9,000,000
