Answer:
The required height of the lighthouse is given as 160 ft tall.
Given that,
A scale model of a lighthouse has a scale of 1 in. : 8 ft. The scale model is 20 inches tall.
What is the scale factor?
The scale factor is defined as the ratio of the modified change in length to the original length.
What is the Ratio?
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
here,
scale factor = 1 / 8 in per ft
Now,
The actual length of the lighthouse = 20 / [1 / 8]
= 20 × 8 = 160 ft
Thus, the required height of the lighthouse is given as 160 ft tall.

Answer:Why this again? math is simple but this is not even though I’m in 6th grade. True false false true
Step-by-step explanation: true , false , false , true
Answer:
truefalsefalsetrue=======================================================
Explanation:
Problem 1
A rational number is any fraction of integers such as 2/3 and 4/7. An irrational number is something that cannot be written as this type of fraction. A famous example is the number pi = 3.14...
This means that any irrational number is not rational, and by extension is not an integer or whole number either. Any integer is automatically rational. Example: 7 = 7/1.
This is why the first answer is true
--------------
Problem 2
Refer to the explanation for problem 1. I talked about how the whole numbers are completely separate from the irrational numbers. Therefore, we arrive at an answer of false.
--------------
Problem 3
This is false because any whole number like 13 can be written as a fraction. 13 = 13/1
Therefore, any whole number is automatically rational.
--------------
Problem 4
This is true. The rational number 2/3 isn't a whole number, but 13 = 13/1 is whole number.

15/7 + h = 37/7
h = 22/7.
choose the correct reasoning for why h=22/7
A. h=22/7 Because 37/7 is 22/7 more than 15/7
B. h=22/7 Because 37/7 is 22/7 less than 15/7
Answers
Answer:
Given [tex]\frac{15}{7} + h = \frac{37}{7}[/tex]
When h = [tex]\frac{22}{7}[/tex]
[tex]\frac{15}{7} + \frac{22}{7} = \frac{37}{7}[/tex]
We add 15 and 22 on the left side, because the denominators are equivalent.
15 + 22 = 37, [tex]\frac{37}{7}[/tex] = [tex]\frac{37}{7}[/tex]
So this statement is true.
That means the correct option is A.

C: 258 cm2
D: 294 cm2

The area of the given trapezoid, using the given dimensions, is calculated to be 150 cm2, which is not among the provided choices, hence none of them are correct.
Explanation:The figure described seems to be a trapezoid, which is a five-sided figure with two parallel sides. The formula to calculate the area of a trapezoid is (base1+base2)/2 * height. In this case, we have one base being 18 cm (the shorter parallel side), but we don't have the length of the other base. However, given the height and the two components of the unknown base, we can infer the remaining base is 7 cm (4 cm from vertex to height and 3 cm from a point to a vertical line created by two vertices). Thus, given the indices, the calculation would be: (18cm + 7cm)/2 * 12cm. Therefore, the total area of the figure is 150 cm2, which is not an option in the given choices. Hence, none of the options A, B, C, D are correct based on the provided data.

Two numbers have a sum of 7. When the smaller number is subtracted from twice the larger number, the result is 20. Which of the following is the largest number?:
(1): 9
(2): 11
(3): 12
(4): 15
Answers
That is the largest
according to the condition it is possible to make up a system of two equations (if to suppose '"' - the larger number and the 's' - is the smaller one):
1. 'two numbers have a sum of 7' means stI=7;
2. 'When the smaller number is subtracted from twice the larger number, the result is 20' means 2*1-5=20.
3. the system of two equations is:
^ $+l=7
12141=20 => 19=03
4. the larger number is 9.
To paint a house, a painting company charges a flat rate of $500 for supplies, plus $50 for each of labor.
Answers
Answer:
A=$1,500, $3,000
B=Y=50x+500 (explained below)
Step-by-step explanation:
you start with the funtion “y=mx+b”. m is the slope, and b is the y intercept. x is how far right or left the point is and y is how far up or down the point is. Then you plug in the information you know. If they charge $50 for each hour, you plug that into the slope, and plug the $500 into the y intercept because that is the initial price, no matter how long it takes them. After you plug those in, it will look like “y=50x+500”. Then you look at what A is asking, for 20 or 50 hours of labor. On the graph it show you that hours is on the x-axis, so you plug the numbers into the equation. The first one, 20, would look like “50(20)+500”. Then the simple part, you solve it. 50 times 20 is 1,000 and 1,000 plus 500 is 1,500. So if they were to work for 20 hours, it would cost $1,500. You do the same for the second one, looking like “50(50)+500” ending up to 3,000. Those are your answers for A. For B, you need to plot the line. You take the easy one, with x being 0. You plot a dot on the y-axis, at (0,500), then you need to plug a number in for the second one, lets take the first number shown on the x-axis, 10. You plug it into the formula, looking like “y=50(10)+500” ending up at “y=1,000” so you plot another dot at (10,1,000). You then take a straight edge, line up the two dots, and draw your line.

_____miles
Answers
Answer:
11 miles
Step-by-step explanation:
6 miles/60 min = 0.1 miles per minute = 0.1x110 = 11
1. Find the unit rate:
60 divided by 6 is 10
2.divide 110 from the amount of minutes it takes you to walk one mile(10)
110 divided by 10 is 11
3.(OPTIONAL) Check your answer
10 times 11 is 110
Therefore Paris would walk 11 miles in 110 minutes

Step-by-step explanation:
Answer: hope this helps ♡
The coordinates of F' are (2,11).
Step-by-step explanation:
right & left = x up & down = y
right & up = positive (+) left & down = negative (-)
F = (6,8)
4 units left = 6 - 4 (x - 4) = 2
3 units up = 8 + 3 (y + 3) = 11
F = (6,8) → (2,11)
