Answer:
Step-by-step explanation:
I'm not sure what you mean by those steps mean but here is how I would answer using the elimination method:
3x - 12y = 5
minus (each term separately: 3x - 3x, -12y - -y, and 5 - 9)
3x - y = 9
This eliminates the 3x and = -11y = -4
You can then simplify from there and get y = 4/11
To the nearest tenth, what is the area of a circle whose diameter is 4.4 feet?
Use 3.14 for π.
Enter your answer in the box.
ft²
Answer:
15.21= 15.2 when rounded
Step-by-step explanation:
the formula for finding the area of a circle with the diameter is
A= 1/4 × π ×d^2
Answer:
15.21
Step-by-step explanation:
In order to find the area, you must find the radius first.
The diameter (4.4) divided by 2 = radius (2.2)
The area of a circle is pi times the radius squared ([tex]A = \pi r^{2}[/tex]).
In this situation, r, or radius =2.2.
[tex]A = \pi 2.2^{2}[/tex]
[tex]\pi[/tex][tex]2.2^{2}[/tex]= the area, 15.2053084434.
By rounding to the nearest hundredth, you get 15.21. The second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.

A corner store sells 60-watt bulbs in packs of 4.
Write an equation that shows how the number of bulbs in stock, y, depends on the number of packages, x.
Answer: y = -4x + 60
Step-by-step explanation:
we can use a simple linear equation to write this problem:
y = mx + b
The slope is given to be the number of bulbs in each pack, which is 4.
now we have: y = 4x +b
The value of b is the y intercept, or the starting value, 60. From this value, 4x can be subtracted to show our remaining bulbs in stock:
y = 60 - 4x
Writing this in the form y = mx+b gives us the equation:
y = -4x + 60
Answer:
y = 4x
Step-by-step explanation:
A corner store sells 60-watt bulbs in pack of 4.
x = number of packs
y = number of bulbs
y = 4x
Check your answer using the problem:
60 = 4x
/4 /4
12 = x
This means that there are 12 bulbs in each pack.

Apollo 16's mission lasted just over 1 week 4 days. How many hours are there 1 week 4 days?
Answer:
264 hours
Step-by-step explanation:
there are 7 days in a week + 4 is 11
11 x 24 (HOURS IN A DAY) = 264 hours
hope this helps
Answer:
264 hours
Step-by-step explanation:
1 week = 7 days
1 day = 24 hours
Therefore, 7 · 24 = the number of hours in a week.
24 · 7 = 168
There are 168 hours in a week.
1 day = 24 hours
4 days = ? hours
4 · 24 = the number of hours in 4 days
24 · 4 = 96
There are 96 hours in 4 days.
You add 168 and 96 hours to get the total number of hours.
168 + 96 = 264

How much wood is needed to build all 4 props?
Enter your answer in the box.
ft²
Answer:
33600
Step-by-step explanation:
256 ft² wood will be needed for 4 props.
What is Surface Area?The area is the space occupied by a two-dimensional flat surface. It is expressed in square units. The surface area of a three-dimensional object is the area occupied by its outer surface.
According to the figure,
The lengths are
= (5ft +8ft +7ft +2ft +3ft +5ft) x 2 x 4
= 32 x 2 x 4
= 256 ft²
Thus, 256 ft² wood will be needed for 4 props.

Step-by-step explanation:
The Surface Area of a triangular prism is L(s1 + s2 + s3) + 2*base area
a = 5m
b = 12m
c = 13m
L = 11m
First, we need to find the base area...
base area = (a*b)/2
(5*12)/2 = 30 m^2
Next, find the surface area
A = 11(5 + 12 +13) + 2*30 = 390 m^2

Let the first angle be 'a'
second angle be (a-150°)
a+(a-150°) = 180°
2a=180°+150°
2a=330°
a=330/2
