Which number line can be used to find the distance between (4, -1) and (8, -1)?
Answers
Answer:
I am not sure, but I believe it is the last one. Sorry if it's not right.
Answer:
The first number line
Step-by-step explanation:
Hey There!
The answer is the first number line because the y values in the given coordinates are the same so all we have to do is plot the x values (4 and 8) and we can find the distance between the two points. The first number line has 4 and 8 on it therefore that is the answer.

Answers
Answer: #5 = -3 #6 = 0, there is no x
Step-by-step explanation: #5 - first you have to turn it into slope-intercept form. So, 3y+12=-9x will become y= -3x -4 because you divide all sides by 3 and you transpose 12 so it becomes negative... then you will pick out you slope which is the number in front of x so slope = -3
#6 - the slope is zero because there is no x in that equation.

7) My savings account increases in value by 4% every year. I started with
$10,000. Which of the following equations can be used to represent the
value of my account over time. *
f(x) = 10000(0.04)^x
f(x) = 10000(1 -0.04)^x
Of(x) = 10000(1.04)^x
O f(x) = 10000(0.96)*x
Answers
Answer: 10000(1.04)^x
Step-by-step explanation: every year your interest increases 4%
And you get multiplier 1.04. After first year you have 10400 and next year you multiply it by 1.04 again.

the bill comes out to 65.35 an the sales tax is 7.7% what is the total amount of the bill
Answers
Answer:
$70.38
Step-by-step explanation:
7.7% = 0.077
Since you are adding 7.7 percent to $65.35, you add a 1 to the decimal form of 7.7%, then multiply.
65.35 x 1.077 = 70.38
Answer:
The bill will come out to be $73.80
Step-by-step explanation:
Take the bill and divide it by the tax and you'll get 8.4
Add 8.4 to 65.35 and you'll get 73.80
Two families went to Rollercoaster World. The Garcia family paid $170 for 3 children and 2 adults. The McGruder family paid $360 for 4 children and 6 adults.
If x is the price of a child’s ticket in dollars and y is the price of an adult’s ticket in dollars, write a system of equations the models this situation.
Answers
Answer:
3x +2y =170 ---equation 1
4x +6y =360 ---equation 2
Price of child 's ticket =$30
price of an adult’s ticket =$40
Step-by-step explanation:
Let x represent the price of a child’s ticket in dollars
and y represent the price of an adult’s ticket in dollars
Such that
3 children and 2 adults for the cost of $170 be represented as
3x +2y =170 ---equation 1
4 children and 6 adults for the cost of $360 be represented as
4x +6y =360 ---equation 2
3x +2y =170 ---equation 1
4x +6y =360 ---equation 2
bY Elimination method Multiplying equation 1 by 4 and equation 2 by 3
12x+8y =680---equation 3
12x +18y =1080---equation 4
Subtracting equation 3 from 4
10 y=400
y =400/10
y=40
Puting the value of y=40 in equation 1 to foind x
3x +2y =170
3x+2 x 40= 170
3x+80 =170
3x=170-80
3x=90
x=90/3=30
Price of child 's ticket =$30
price of an adult’s ticket =$40
Find the sample size required to achieve the given margin of error with SD = 51.02 and z - score = 1.96. Round your answer to the nearest whole number. margin of error = 2
Answers
Answer:
The sample size required is 2500.
Step-by-step explanation:
z-score:
In function of the margin of error M, the z-score is given by:
[tex]Z = \frac{M}{\frac{\sigma}{\sqrt{n}}} = \frac{M\sqrt{n}}{\sigma}[/tex]
In this question, we have that:
[tex]\sigma = 51.02, M = 2, Z = 1.96[/tex]
So
[tex]Z = \frac{M\sqrt{n}}{\sigma}[/tex]
[tex]1.96 = \frac{2\sqrt{n}}{51.02}[/tex]
[tex]2\sqrt{n} = 51.02*1.96[/tex]
[tex]\sqrt{n} = \frac{51.02*1.96}{2}[/tex]
[tex](\sqrt{n})^2 = (\frac{51.02*1.96}{2})^2[/tex]
[tex]n = 2500[/tex]
The sample size required is 2500.
A rectangle has an area of 54 square inches and a length of 6 in what is the width in inches of the rectangle?
Answers
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Areas and Volumes.
We know that, Area of a Rectangle = length * Width.
Since,here Length = 6 inch and Area = 54 square inches,
==> Width = Area / length
==> Width = 54/6
=> Width = 9 inches.
Hence the width of the rectangle is 9 inches.
