Drew needs to air up his teams 8 soccer balls. Each ball has a diameter of 70cm. In terms of pi, what is the total volume of air in all 8 soccer balls?
Answer:
1.44m^3
Step-by-step explanation:
Given data
Number of balls= 8
Diameter of ball = 70cm = 0.7m
Radius= 35cm= 0.35m
We know that a ball has a spherical shape
The volume of a sphere is
V= 4/3πr^3
substitute
V= 4/3*3.142*0.35^3
V= 0.18m^3
Hence if 1 ball has a volume of 0.18m^3
Then 8 balls will have a volume of
=0.18*8
=1.44m^3

Complete question :
From Monday through Friday, James works in the library on 2 days and in the cafeteria on another day. On Saturday and Sunday, James washes cars 50% of the days. How many days does James work in a week? What percent of the days from Monday through Friday does he work?
Answer:
4 days ;
60%
Step-by-step explanation:
From Monday to Friday
Number of days in library = 2
Number of days in cafeteria = 1
50% of days in weekends
Number of weekend days = 2
50% of 2 = 0.5 * 2 = 1 day
Total. Number of days worked = (2 +1 + 1) = 4 days
What percent of the days from Monday through Friday does he work?
Number of days workwd from. Monday to Friday = 3
Total number of days from Monday to Friday = 5
Percentage of days worked from Monday to Friday
= number of days worked / total number of days
= 3 /5 * 100%
= 0.6 * 100%
= 60%

What is Measurement unit?A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.
Given that,
The distance completing in 1 hour = 20 miles
So 1 miles of distance is covered in = 1/20 hours
It is also given that,
The distance of rally = 24 miles.
Therefore,
The time taken to cover 24 miles = 24/20
= 1.2
Thus,
The required time = 1.2 hours

Someone please help me outttttttttttt
Answer:
the answer should be
[tex]12 \sqrt{2} [/tex]
Step-by-step explanation:
the shorter leg of a right triangle (in this case it would be BC) is always half the value of the longest side, AB. So if AB is 24\/2, half of that should be 12\/2. So, since BC =X, then X=12\/2.

Answer:
Step-by-step explanation:
4(2x+10)=0
8x+40=0
-40 -40
8x=-40
x=-5
Answer:
-5
Step-by-step explanation:
First you have to distribute 4 to 2x and 10, giving us 8x + 40 = 0. Then subtract 40 from both sides, giving us 8x = -40. Now divide -40 by 8, which gives us -5.

The surface area is the two-dimensional area around a three-dimensional surface. In other words, if one was going to wrap the figure, the surface area is the amount of paper one would need. One can find the surface area by finding the area of each individual side and then adding all the results together. To find the area of a 2-dimensional figure by multiplying the length by the width.
(4.5) * (6.8) = 30.6
(4.5) * (6.8) = 30.6
(2.2) * (6.8) = 14.96
(2.2) * (6.8) = 14.96
(4.5) * (2.2) = 9.9
(4.5) * (2.2) = 9.9
Now add up all of the values,
30.6 + 30.6 + 14.96 + 14.96 + 9.9 + 9.9
= 110.92

Somebody please help me out. How do I find the surface area of a rectangular prism?
Answer:
A=2(wl+hl+hw)
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
Answer:
Option (C) 198 cm² will be the answer.
Step-by-step explanation:
Surface area of rectangular prism=2(lb+bh+lh)
where l=length, b=breadth and h=height.
Here, the length is 9cm, breadth is 6cm and height is 3cm.
By applying the formula,
2{(9*6)+(6*3)+(9*3)}
2{54+18+27}
2*99

Pablo saves $85 per month for 6 months. Then he deposits the money in an account that earns 2.1% simple interest. How much interest will he earn over 4 years? (no links just answers)
Answer:
$42.84
Step-by-step explanation:
P = 85 * 6 = 510
Formula:
I = Prt
Given:
P = 510
r = 2.1% or 0.021
t = 4
Work:
I = Prt
I = 510(0.021)(4)
I = 42.84
The next question(s) are based on this scenario: A researcher randomly assigned boys and girls to each of two groups. One group watched a violent television program while the other group watched a nonviolent program. The children were then observed during a period of free play, and the incidence of aggressive behavior was recorded for each group. What is the independent variable in this study
Answer:
The type of television program viewed
Step-by-step explanation:
The Independent variable may be explained as those variables which determines the outcome or output of an experiment or analysis. The output is the dependent variable. Hence, the independent variable determines the predicted variable.
In the scenario described above, the type of television program viewed, either violent or nonviolent is the independent or predictor variable. This determines the level or incidence of aggressive behavior exhibited by the subject, this incidence of aggressive behavior is the dependent or predicted variable.

State whether or not the following triangles are similar. If not, explain why not. If so, write a similarity statement
9514 1404 393
Answer:
a) ∆RLG ~ ∆NCP; SF: 3/2 (smaller to larger)
b) no; different angles
Step-by-step explanation:
a) The triangles will be similar if their angles are congruent. The scale factor will be the ratio of any side to its corresponding side.
The third angle in ∆RLG is 180° -79° -67° = 34°. So, the two angles 34° and 67° in ∆RLG match the corresponding angles in ∆NCP. The triangles are similar by the AA postulate.
Working clockwise around each figure, the sequence of angles from lower left is 34°, 79°, 67°. So, we can write the similarity statement by naming the vertices in the same order: ∆RLG ~ ∆NCP.
The scale factor relating the second triangle to the first is ...
NC/RL = 45/30 = 3/2
__
b) In order for the angles of one triangle to be congruent to the angles of the other triangle, at least one member of a list of two of the angles must match for the two triangles. Neither of the numbers 57°, 85° match either of the numbers 38°, 54°, so we know the two triangles have different angle measures. They cannot be similar.

A square and rectangle are shown below. The width of the rectangle is the same as the length of a side of the square, both represented by x. The length of the rectangle is one foot more than twice its width. The perimeter of the rectangle is 26 feet more than that of the square.
A). Write an expression for the length of the rectangle in terms of x. Label the drawing
B). Show that 5 could not be the value of x
C). Set up an equation and solve it to find the value of x
THANKS FOR THE HELP!!!
Answer:
Since this is a multi-part question, just look at the bolded parts under each letter. I hope this helps a bit ;)
Step-by-step explanation:
A)
All sides of a square are congruent. "s" represents the square's perimeter:
s=4x.
"r" is the rectangle's perimeter:
r= 4x+26
since the perimeter = 2W + 2L:
2W + 2L= 4x+ 26
and W=x, so:
2x + 2L= 4x + 26
Subtract from both sides:
2L= 2x +26
Divide both sides:
the length of the rectangle "L"= x +13.
B) Plug 5 into the equations:
L= 5+ 13 or 18.
2(18) + 2(5)= r
36+ 10 = r or 46
s= s+ 26
s= 46-26 or 20.
20/4= 5...
It seems (at least to me, feel free to give constructive criticism) that the only logical conclusion is that 5 could be the value of x.
C) You would likely need to use substitution to solve, but unless I am much mistaken, this looks like an infinite-solutions equation.
