The perimeter of a rectangular lot is 86 feet. The
length is 19 feet greater than the width. Find the
length and width.
Answer: width would be 7 feet and the length would be 26
Step-by-step explanation:
width : w
length: 19 +w
2l + 2w = 66
2(19+w) + 2w= 66 distribute
38 + 2w + 2w = 66 add the w values
38 + 4w =66 subtract 38 from both sides
4w = 28 divide by 4
w= 7
19+7= 26
l=26

There will be around 1024 viruses, from single virus, in the system after 10 divisions. This is related to Linear equation.
Linear EquationIn the question we are provided with the information that the virus divides itself into two, at every time interval.
Hence, in the number system, we can write it down as 1, 2, 4, 8....to 10th divison. The linear equation will be 2(2)^n-1.
Where n is equal to number of divisions, and the value 2 is the virus bening multiplied by 2.
Hence the value after 10th division will be 2(2)^10-1
2×2^9 = 1024.

"8 cm I Circumference cm" can someone explain how to do this? plz?
Answer:
The area of a circle is [tex]\pi r^{2}[/tex] which is given in the question. (r is radius)
The radius is the length from the centre of the circle to the border of the circle (8cm in this case)
Area of circle:
[tex]\pi r^{2} =\pi *8^{2} =64\pi =201.06cm^2[/tex] (2 decimal places)
Circumference of circle:
[tex]\pi d[/tex] (d is diameter)
The diameter is twice the radius and it is the length of a point on the circle to the opposite point of it.

∠1 and ∠2 form a linear pair. If m∠1 = 5x + 9 and m∠2 = 3x + 11, find the measures of both angles.
Answer:
∠1 =109
∠2= 71
Step-by-step explanation:
if they are a linear pair that means they must both (when added together) equal 180 degrees, so this means we can add them and set them equal to 180!
8x+20=180
8x=160
x=20
then we just input them!
m∠1 = 5(20) + 9 = 109
m∠2 = 3(20) + 11 = 71

of people of the same sex and similar ages follow a Normal distribution reasonably closely. Weights, on the other hand, are not Normally distributed. The weights of women aged 20–29 in the United States have mean 161.9 pounds and median 149.4 pounds. The first and third quartiles are 126.3 pounds and 181.2 pounds, respectively. What can you say about the shape of the weight distribution? Why?
Answer:
Right-skewed
Step-by-step explanation:
The shape of the weight distributed is skewed, because the mean and the median are not equal.
Moreover, the distribution is right-skewed because the mean is greater than the median and because the mean is influenced by the tail of large values.

5(x+8)+3
3.6x-7-5.1x
4+8x+2.2-10x
Answer:
1. 5x +43
2. -1.5x - 7
3. 6.2 - 2x
Step-by-step explanation:
Equation 1:
5 (x+8) +3
First, we can distribute the 5 to the (x+8) and get 5x + 40. Distributing is when we multiply the 5 by the first number (x) and then by the second number (8) Because they aren't like terms (don't both have x's) we cannot combine then and must keep them separated by a subtraction sign
Now we have: 5x + 40 + 3
Next, we can combine the like terms. This means that any that have the same variable can be combined. So, the 5x has no other x's so he has to stay how he is. The 40 and the 3, however, can be added together to get 43.
Our finished equation is: 5x + 43
Equation 2:
3.6x - 7 - 5.1x
First, we can combine like terms as we learned in the last problem. This would be our x's since we have multiple.
We can add 3.6x and -5.1x and get -1.5x
Now we have: -1.5x - 7
Equation 3:
4 + 8x + 2.2 - 10x
We can start with either the numbers with x's or without but I'll just do the x's. So we have 8x and -10x. Adding these together would get us -2x.
Next, we can combine 4 and 2.2 and get 6.2.
Now, putting these back into our equation would look like this:
6.2 - 2x

2x+3y=7 solve for y.
Answer:
[tex]y=\frac{7}{3}-\frac{2}{3}x[/tex]
Step-by-step explanation:
To solve for y, we will have to get y by itself on one side of the equation, with all of the other variables and values on the other side.
2x + 3y = 7
Subtract 2x to both sides of the equation.
3y = 7 - 2x
Divide both sides by 3.
[tex]y=\frac{7}{3}-\frac{2}{3}x[/tex]
And now we have solved for y.

All pictures are below please help Sandi had the following problem on her math test: . She showed her work on the test as follows: Given: Step 1: Step 2: Step 4: Step 5: In at least two paragraphs, explain the steps Sandi took to arrive at her answer. If she made any errors in her process clearly explain what she did wrong and how she could have made the error. If there is an error, provide the correct steps in your explanation of Sandi’s work. Use correct math terminology wherever appropriate.
Answer/Step-by-step explanation:
The basic rule of maths operation used by Sandi, is the PEMDAS Rule.
Maths operations like the one Sandi was given must follow this rule. According to the rule:
P - Parentheses, solve everything you have in the parentheses first.
E - Exponents, do the exponents.
M - Multiplication or
D - Division operation should come next.
A - Addition or
S - Subtraction comes last.
Let's apply this rule to see if Sandi rightly applied the PEMDAS Rule:
Step 1:
6*4 + 2 ÷ 2 - 7 (given)
Step 2: perform operation involving Multiplication first according to PEMDAS Rule.
24 + 2 ÷ 2 - 7 (multiplication first. I.e. 6*4 = 24)
Step 3: perform division operation next.
24 + 1 - 7 (division operation. i.e. 2÷2 = 1)
Step 4: Subtraction
24 - 6 (i.e. +1 - 7 = -6) this is where Sandi made an error.
Step 5: subtraction
24 - 6 = 18.
Sandi made a mistake in step 4 and 5. Her addition and subtraction operation was wrong. 1 - 7 = -6 not +6.
During operation like this, either subtraction or addition can come first.
