Answer:
x = -516
Step-by-step explanation:
(4 - 5x) + 43 = 3 - 32(-82) {Multiply 32 and (-82)}
4 - 5x + 43 = 3 - (-2624)
4 - 5x + 43 = 3 + 2624 {add 4 and 43 in LHS}
-5x + 47 = 2627 {Subtract 47 from both sides}
-5x = 2627 - 47
-5x = 2580 {Divide both sides by (-5)}
x = 2580/(-5)
x = -516
Hal has a steel barrel with a diameter of 6 feet that can be filled to a depth of 4.6 feet with oil. What is the volume of the barrel?
Use = 3.14
OA 93.696 cubic feet
OB. 154.116 cubic feet
OC. 129.996 cubic feet
OD 124.2 cubic feet
Answer:
129.996 cubic feet
Step-by-step explanation:
Assuming that the barrel is a perfect cylinder, we can use the formula to find the volume:
[tex]\pi(r)^2(h)[/tex]
First, we have to find the radius, which is:
D = 2r
So the radius is 3 feet, since it is half of the diameter. Then, we plug in the values.
[tex]3.14(3)^2(4.6)[/tex]
Now, we solve. Exponents are first...
3.14(9)(4.6)
Now multiply left to right.
28.26(4.6)
129.996 cubic feet
Therefore, the barrel can hold 129.996 cubic feet of oil. Hope this helps you!
Work on the screenshot
Answer:
12 gallons
Step-by-step explanation:
If it takes 20 h for 5 gallons to be filled, it takes 4 h for 1 gallon to be filled. This is the ratio. You multiply 4 h by 12 to get 48 h, so you multiply 1 gallon by 12 as well. This is 12 gallons.
Evaluate log2 8.
1) 0.25
2) 0.33
3) 3
4) 4
Answer:
log 2 8 is 3.
Step-by-step explanation:
Log2 8=Log(8) ÷ Log(2)
Log(8)= 0.903089986992
Log(2)=0.301029995664
Log2 8=0.903089986992 ÷ 0.301029995664

Answer:
W = 87 degrees
Step-by-step explanation:
First we can rearrange the question so that W is isolated on the left side, which we do by dividing both sides by tan:
tanW/tan = 19.0811/tan
W = 19.0811/tan
Now we can use the inverse tan function on the calculator ([tex]tan^{-1}[/tex]) to calculate it:
W = 19.0811 x [tex]tan^{-1}[/tex]
W = 87 degrees

i five man take 45 hours to build a wall how long will it take 9 men working at the same pace to build this wall
Answer:
81 hours
Step-by-step explanation:
Let x be the time are needed
45：5 = x：9
5x = 45×9
5x = 405
x = 81
The time it takes 9 men working at the same pace to build this wall is 81 hours
Ratio and proportionsLet x be the time are needed for 9men
If it takes five-man take 45 hours to build a wall then, we can have the ratio
45：5 = x：9
5x = 45×9
5x = 405
x = 81
Hence the time it takes 9 men working at the same pace to build this wall is 81 hours

A regular pentagon with a perimeter of 10 cm is dilated by a scale factor of 3/2 to create a new pentagon. What is the the perimeter of the new pentagon?
Given:
Perimeter of a regular pentagon = 10 cm
The pentagon is dilated by a scale factor = [tex]\dfrac{3}{2}[/tex].
To find:
The perimeter of the new pentagon.
Solution:
If a figure is dilated by a scale factor k, then
Perimeter of new figure = k × perimeter of original figure
The scale factor is [tex]\dfrac{3}{2}[/tex] and the perimeter of a regular pentagon is 10 cm. So, the perimeter of a new pentagon is:
[tex]\text{Perimeter of new pentagon}=\dfrac{3}{2}\times 10[/tex]
[tex]\text{Perimeter of new pentagon}=3\times 5[/tex]
[tex]\text{Perimeter of new pentagon}=15[/tex]
Therefore, the perimeter of the new pentagon is 15 cm.
