Answer:
Length of rectangle = 28 cm
Width of rectangle = 12 cm
Step-by-step explanation:
Perimeter= 80cm
We are given Length:Width = 7:3
We can write them as:
Length =7x
Width=3x
We need to find length and width.
To find length and width we need to find value of x.
The formula used is: [tex]Perimeter= 2(Length+Width)[/tex]
Putting values and finding value for x
[tex]Perimeter= 2(Length+Width)\\80=2(7x+3x)\\40=10x\\x=\frac{40}{10} \\x=4[/tex]
So, length = 7x = 7*4 = 28
Width = 3x = 3*4 = 12
So, Length of rectangle = 28 cm
Width of rectangle = 12 cm

At a carnival, 2 out of the first 8 customers who entered had purchased cotton candy. Based
on this information, if 360 customers were at the carnival, how many customers can be
expected to have purchased cotton candy?
Answer:
90 people are expected to but cotton candy.
Step-by-step explanation:
The answer is 90 because 360 divided by 8 is 45 and 45 multiplied by 2 is 90.

What is Quadratic equation?
Any equation that can be transformed into standard form as follows is referred to as a quadratic equation in algebra (from the Latin quadratus, which means "square").Where x denotes an unknown and a, b, and c denote known values, respectively, with a 0, displaystyle ax2+bx+c=0 is used. Since there is no displaystyle ax2ax2 term, the equation is linear (if a = 0 and b 0) rather than quadratic.) The coefficients of the equation are the numbers a, b, and c, which can be separated by referring to them as the quadratic coefficient, linear coefficient, and constant or free term, respectively. As well as being referred to as the roots or zeros of the expression on the left-hand side of the equation, the values of x that satisfy it are known as solutions of the equation. There are only two possible answers to a quadratic equations The quadratic formula. The solutions are expressed in terms of a, b, and c by the expression sqrt b2 4ac 2a. There are numerous ways to obtain it, one of which is through completing the square.
Quadratic equation-based solutions to issues have been recognized since 2000 BC.The quadratic equation is referred to as "univariate" because there is just one unknown. The quadratic equation is a polynomial equation because all the powers of x that it contains are non-negative integers. Since the largest power is two, it is in particular a second-degree polynomial equation.

Triangle M was dilated by a scale factor of 1.2 to form triangle M. How does the area of triangle M'
relate to the area of triangle M?
A- The area of triangle M'is 0.6 times the area of triangle M.
B- The area of triangle M'is 1.2 times the area of triangle M.
C- The area of triangle M'is 1.44 times the area of triangle M.
D- The area of triangle M' is 2.4 times than the area of triangle M.
Answer:
The area of triangle M is 1.44 times the area of triangle M.
Step-by-step explanation:
From Geometry we remember that the area formula of the triangle is:
[tex]A = \frac{1}{2}\cdot b\cdot h[/tex] (1)
Where:
[tex]b[/tex] - Base of the triangle, dimensionless.
[tex]h[/tex] - Height of the triangle, dimensionless.
[tex]A[/tex] - Area of the triangle, dimensionless.
The dillation of the triangle by a scale factor means that:
[tex]A' = \frac{1}{2}\cdot b'\cdot h'[/tex] (2)
[tex]b' = k\cdot b[/tex] (3)
[tex]h' = k\cdot h[/tex] (4)
Where:
[tex]b'[/tex] - Dilated base of the triangle, dimensionless.
[tex]h'[/tex] - Dilated height of the triangle, dimensionless.
[tex]A'[/tex] - Dilated area of the triangle, dimensionless.
[tex]k[/tex] - Dilation factor, dimensionless.
If we know that [tex]k = 1.2[/tex], then the area formula for the dilated triangle is:
[tex]A' = \frac{1}{2}\cdot (k\cdot b)\cdot (k\cdot h)[/tex]
[tex]A' = k^{2}\cdot \frac{1}{2}\cdot b\cdot h[/tex]
[tex]A' = k^{2}\cdot A[/tex]
Therefore, the area of triangle M is 1.44 times the area of triangle M.
Answer:
C- The area of triangle M'is 1.44 times the area of triangle M.
Step-by-step explanation:
1.44 divided by 1.2=1.2

Find the value of p in the equation, 0.25p-50=240
Answer:
p = 1160
Step-by-step explanation:
0.25p-50=240
0.25p = 240+50 (Transfer the 50 and isolate the p)
[tex]\frac{1}{4}[/tex]p = 290 (Changing the decimal to a fraction so it is easier to see)
[tex]\frac{4}{4}[/tex]p = 4×290 ([tex]\frac{1}{4}[/tex]×4 = [tex]\frac{4}{4}[/tex])
p = 1160
Answer:
p=1160
Step-by-step explanation:
Its's easy. If there ever is any number with a letter in the equation, you are most likely to divide that number. First, since 50 has a minus in front of it, you have to add that to the 50 in the equation AND the 240. When you do 50 plus the 50 in the equation it cancels out because -50+50 is 0 (you don't add the 0 to the equation because you are looking for p.) So, 240+50 is 290. Now, you have to divide 0.25 to the 0.25p AND the 290. 0.25 divided by 0.25p is 1, BUT you never put 1p you just put p because p is the same as 1. 290 divided by 0.25 is 1160. So your equation should look like p=1160
