The newspaper, The constellation, printed in 1859, had width 20 in and length 35 in. What was the perimeter? What was the area?
Answer:
110 in.
Step-by-step explanation:
newspapers have four sides because it is a square
one side is parallel to the other side.
so
20 × 2 for the width
35 × 2 for the height
20 × 2 = 40
35 × 2 = 70
add together for the perimeter.
40 + 70 = 110 in.
you could also...
20 + 35 + 20 + 35 = 110 in.

Can someone help me find the scale factor and the missing sides please?
Answer:
x = 6, y = 45
Step-by-step explanation:
[tex]scale \: factor = \frac{13}{32.5} \\ = \frac{2}{5} \\ \\ \frac{x}{15} = \frac{18}{y} = \frac{2}{5} \\ \\ \implies \frac{x}{15} = \frac{2}{5} \\ \\ x = \frac{2 \times 15}{5} \\ \\ x = 6 \\ \\ \frac{18}{y} = \frac{2}{5} \\ \\ y = \frac{5 \times 18}{2} \\ \\ y = 45[/tex]

Tameca already has $55 dollars in her savings account. If she puts $5 per week in her account, write and solve an inequality to find out how many weeks she must save to have at least $100 in her account.
Answer:
9 weeks
Step-by-step explanation:
5 x 9 = 45
45 + 55 = 100
Answer:
55 + 5x ≥ 100.
5x ≥ 45.
Step-by-step explanation:
write the first equation shown above first, then subtract 55 from 55 and 55 from 100. do not use 0 later on in your equation! 100 - 55 = 45. then write the second equation. after you write the second equation, divide 5 by 5 and 45 by 5. do not use 0 later on in your equation! 45 divided by 5 = 9. she must save for 9 weeks. i hope this works! here is a picture of my work to help you understand it better! <3 it’s kind of blurry, but if you focus enough it’s easier to read.
this is 8th grade math and i dont understand it

You are a contractor and charge $65 for a site visit plus an additional $15 per hour for each hour you spend working at the site. Write and solve an equation to determine how many total hours you have to work to earn $950 working at two separate work sites.
Answer:
54.6 hours
Step-by-step explanation:
65x2 is 130 130-950 is 820 then 820 divided by 15 is 54.6 therefore meaning you have to work 54.6 hours to get 950$ you can check this by doing 54.6x15+130, might not be exact because i rounded to the nearest tenth.
Hope this helps!

A rectangle’s width is 8 inches long. If the length is 3 times the width, what is the perimeter of the rectangle?
Answer:
the perimeter is 64
Step-by-step explanation:
the length is 24 because 8*3 = 24 and since it is perimeter of a rectangle there are two sides that are the same length which is the length are 24+24 and width is 8+8 and all together
24+24+8+8=64

Step 1: Identify the slope and y-intercept.
slope =
The slope of given line is -3 and the y-intercept of the line is -2.
What is Straight Line?A straight line is an infinite length line that does not have any curves on it. A straight line can be formed between two points also but both the ends extend to infinity.
Here, we know that slope intercept form of straight line;
y = mx + c
Given equation;
y = -3x - 2
compare this equation with general equation, we get
m = -3 and c = -2
Thus, The slope of given line is -3 and the y-intercept of the line is -2.

b and d are a linear pair, so the sum of their measures is 180 deg.
b + d + 180
85 + d = 180
d = 95
Answer:

Complete question :
Tabby is building two models of the Eiffel Tower. The scale factor of Model 2 to Model 1 is 1/4
____________Eiffel Tower(ft) _ M 1 (in) _M2 (in)
Height _______ 984 ______11.808 ____?
W of base ____ 328 _______? _______?
Answer:
Model 1 :
Width of Base = 328 * 0.012 = 3.936 inch
Model 2 :
Height = 11.808 * 4 = 47.232 inches
Width of base = 4 * 3.936 = 15.744 inches
Step-by-step explanation:
____________Eiffel Tower(ft) _ M 1 (in) _M2 (in)
Height _______ 984 ______11.808 ____?
W of base ____ 328 _______? _______?
Scale factor of Model 2 to Model 1 is 1/4
Model 1 : Model 2
1 : 4
The scale factor of actual tower to model 1
984ft = 11.808 inches
Hence,
1 ft = 11.808 / 984
1 ft = 0.012 inch
Model 1 :
Width of Base = 328 * 0.012 = 3.936 inch
Since ;
Model 1 : Model 2 ; 1 / 4
1 : 4
Model 2 :
Height = 11.808 * 4 = 47.232 inches
Width of base = 4 * 3.936 = 15.744 inches
