Answer:
The mentioned milk truck can hold:
3927 ft^3 of milk.Step-by-step explanation:
As you can see, the question is asking about the volume of the milk truck, to obtain the volume of a cylinder, first we must to find the area of the surface side, in this case is a circle, to find the area of a circle when we have the diameter is:
Area of a circle = [tex]\pi *\frac{\ D^{2} }{4}[/tex]Where D is the diameter given (10 feet), now we replace and operate:
Area of a circle = [tex]\pi *\frac{\ (10 ft)^{2} }{4}[/tex]Area of a circle = [tex]\pi *\frac{\ 100 ft^{2} }{4}[/tex]Area of a circle = [tex]\pi *25 ft^{2}[/tex]Area of a circle = 78.54 ft^2 approximatelyNow, with the data of the area, we can calculate the volume with the formula below:
Volume of a cylinder = Area of the circle * heightVolume of a cylinder = 78.54 ft^2 * 50 ftVolume of a cylinder = 3927 ft^3With the calculations, we can see the milk truck can hold 3927 cubic feet of milk with those dimensions.
The total cost of 8 identical pens and 2 identical files is $32 The total cost of 3 such files is the same as the total cost of 4 such pens. Find the cost of each file
Answer:
$4
Step-by-step explanation:
Given that
total cost of 8 identical pens and 2 identical files is $32
And, the The total cost of 3 such files would be the same as the total cost of 4 such pens
We need to find out the cost of each file
So let us assume the following things
Pens be x
File be y
Now
8x + 2y = $32 ....(1)
3y = 4x.........(2)
y = 4x÷ 3
Now put the value of y in equation 1
8x + 1.33x = 32
x = $3.55
x = $4
The cost of each file based on the given information is $4
where:
Let the cost of a pen be xLet the cost of a file be ySimultaneous equationIf the total cost of 8 identical pens and 2 identical files is $32, hence;
8x + 2y = 32
If the total cost of 3 such files is the same as the total cost of 4 such pens, then;
4x = 3y
From the equation
8x + 2y = 32
2(4x) + 2y = 32
2(3y) + 2y = 32
8y = 32
y = 4
Since 6=4x = 3y
4x = 3(4)
4x = 12
x= 3
Hence the cost of each file is $4

Answer:
The circumference of the circle is 75.36cm
Step-by-step explanation:
There are two ways you can solve this, one is by using the radius and multiplying it by 2 and then pi which is 3.14, and the other is to use the diameter which is the radius times 2, and the thingy gave you the diameter, and you multiply it by 3.14 which is pi

Find the value of x and y
Answer:
2x + 20 = 3x-10
2x -3x = -20-10
-x = -30
x= 30
Checking part:
2x+20 = 2(30) +20 = 60+20 = 80
3x-10 = 3(30) - 10 = 90-10 = 80
Hence, the final answer is x = 30.
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
the angle should be the same so,
2x+20=3x-10
x=30

On simplifying (3+√3 )(5- √2), the value is
A. 112
B. 18
C. 6
D. 21
no spam and please explain ur answer .
Answer:
18
Step-by-step explanation:
( 3 + √3 ) ( 5 - √2 )
= 3 ( 5 - √2 ) + √3 ( 5 - √2 )
= 15 - 3√2 + 5√3 - √6
√2 = 1.41 ( approximately )
3√2
= 3 x 1.41
= 4.23
√6 = 2.44
√3 = 1.73
5√3
= 5 x 1.73
= 8.65
15 - 3√2 + 5√3 - √6
= 15 - 4.23 + 8.63 - 2.44
= 15 + 8.63 - 4.23 - 2.44
= 15 + 8.63 - 6.67
= 15 + 1.93
= 16.93
Rounding of 16.93 = 17
17 is near to 18.
So, 18 can be the answer.
5. A ladder leans against a building. The top of the ladder touches the building 10 feet above the ground. The foot of the
ladder is 4 feet from the building. Find, to the nearest degree, the angle that the ladder makes with the level ground.
(3 points)
Answer:
68 degrees
Step-by-step explanation:
The ladder, the building and the ground together make up a right triangle with angle of elevation to be determined.
The side opposite this angle is 10 ft; the distance of the foot of the ladder from the building is 4 ft. Thus,
tan x = (opp side) / (adj side) = 10/4. Using the inverse tangent function, we find that the angle in question is
arctan (10/4) = 68 degrees
If the measurement of angle 2 is 120 degrees, what is the measurement of angle 7?
Answer:
The measure of angle 7 is twice the measure of angle 2, then the measure of angle 7 is
angles 2 and 7 equal 180 degrees. 180 = 2x + x
180 = 3x
x = 60
angle 7 is twice x
angle 7 = 120
