Answer:
492.87cm^3
Step-by-step explanation:
Given data
Diameter= 4.9cm
The expression for the volume is
V= 4/3 πr^3
Substitute
V= 4/3*3.142*4.9^3
V= 4/3*3.142*117.649
V=1478.612632 /3
V=492.87 cm^3
Hence the volume is 492.87cm^3

Question 1
A cake is cut into 12 equal slices. After 3 days Jake has eaten 5 slices. What is his weekly rate of eating the cake?
Answer:
11.2 Slices / Week
Step-by-step explanation:
We know that Jake has eaten 5 slices of cake in 3 days. You can divide 5 / 3 to get an average of 1.6 slices of cake being eaten per day. The question asks what the weekly rate or eating the cake will be, do you need to multiple 1.6 x 7 for the total amount of cake eaten per week, which is 11.2 slices!

The perimeter of a rectangular swimming pool is 154 m. Its length is 2 m more than twice its breadth. What are the length and the breadth of the pool?
Answer:
Length of the pool = 52 m
Width of the pool = 25 m
Step-by-step explanation:
Perimeter of rectangular pool = 154 m
Let the length of rectangular pool = l m
And width of the rectangular pool = w m
Formula, to calculate the perimeter of a rectangle is given by,
Perimeter = 2(Length + width)
By substituting values in the formula,
154 = 2(l + w) --------(1)
Since, "length of the pool is 2 m more than twice of its breadth"
l = 2 + 2w ---------(2)
Bu substituting value of 'l' from equation (2) to equation (1),
154 = 2[(2 + 2w) + w]
154 = 2(3w + 2)
77 = 3w + 2
3w = 75
w = 25 m
From equation (2),
l = 2 + 2(25)
l = 2 + 50
l = 52 m
Therefore, length of the rectangular pool is 52 m and width is 25 m.

1. A fast food outlet claims that the mean waiting time in line is less than 3.8 minutes. A random sample of 60 customers has a mean of 3.7 minutes with a population standard deviation of 0.6 minute. If α = 0.01, test the fast food outlet's claim.
Answer:
There is no significant evidence to conclude that the mean waiting time is less than 3.8 minutes
Step-by-step explanation:
H0 : μ = 3.8
H1 : μ < 3.8
Test statistic :
(x - μ) ÷ s/sqrt(n)
(3.7 - 3.8) ÷ 0.6/sqrt(60)
Test statistic = - 1.29
The Pvalue from test statistic :
P(z < -1.29) = 0.0985
Reject Null if
Pvalue < α
0.0986 > 0.01 ; Hence, we fail to reject the null ;
There is no significant evidence to conclude that the mean waiting time is less than 3.8 minutes

Plzzz hurry
Answer:
8
Step-by-step explanation:
If each baseball= 4 homeruns, and Chester has 5 baseballs next to his name (20 homeruns), then Evan hit 12 home runs because 4*3= 12 and he has 3 baseballs next to his name.
20-12=8
The graphs of y = 4x and y = 4x are shown below.
In general, how does the growth of y = 4x compare to the growth of y = 4x?
The function y = 4x is growing slower than y = 4x.
The function y = 4x is growing faster than y = 4x.
The functions y = 4x and y = 4x are growing at the same rate.
The function y = 4x is growing faster than y = 4x.
For this case we have the following functions:
y = 4x
y = 4 ^ x
We observed that :
The graph y = 4 ^ x is growing faster than y = 4x, because for smaller values of x, it has the same range as y = 4x.
Answer:
The graph y = 4 ^ x is growing faster than y = 4x

a diagram is shown, with angels labeled in degrees complete the sentences about the diagram
Answer:
Equation: 5x = 90
x = 18
<LNM = 54degrees
Step-by-step explanation:
From the diagram shown;
<JNK + <KNL + <LNM = 90
x + x + 3x = 90
5x = 90
x = 90/5
x = 18
The equation 5x = 90 can be used to solve for x
Get <LNM = 3x
<LNM = 3(18)
<LNM = 54 degrees
"The frequency of an event uses counting numbers, but the __________________ of an event uses a percent or a number between 0 and 1."
The frequency of an event uses counting numbers, but the ___Relative Frequency__ of an event uses a percent or a number between 0 and 1.
How to find the relative frequency?Relative frequency is the ratio of the considered sub group's count to the total count. (so its frequency of the considered sub group relative to the total frequency).
It ranges from 0 to 1 (since sub group's count ≤ total count. Expressing this decimal form to percent make it range from 0% to 100%
Thus, the frequency of an event uses counting numbers, but the ___Relative Frequency__ of an event uses a percent or a number between 0 and 1.

Linda will spend more than $29 on gifts. So far, she has spent $16. What are the possible additional amounts she will spend?
Use c for the additional amount (in dollars) Linda will spend.
Write your answer as an inequality solved for c.
Answer:
c ≥ $13
Step-by-step explanation:
We know that Linda will spend more than $29 on a gift.
This means that if S is the total amount she will spend on the gift, the minimum that she can spend is $29, we can write this as:
S is larger than or equal to $29
S ≥ $29
Now we know that she already spent $16, then we can write:
S = $16 + c
Where c is the additional amount she will spend.
Replacing that in our inequality we get
$16 + c ≥ $29
Now we can subtract $16 in both sides to get:
$16 + c - $16 ≥ $29 - $16
c ≥ $29 - $16 = $13
c ≥ $13
This means that she will spend at least another $13,
Find in the triangle. Round to the nearest degree.
a.
45°
C. 60°
b. 59°
d. 42°
Answer:
Theta = 59 degrees
Step-by-step explanation:
Here, we want to get the value of the marked angle
To do this, we use the appropriate trigonometric ratio
From what we have,
The side 42 ft is adjacent the angle given
The side facing the right angle is 82 ft
The trigonometric ratio that connects the adjacent and the hypotenuse is cosine. It is the ratio of the adjacent to the hypotenuse
Cos theta = 42/82
theta = cos^-1 0.5122
theta= 59.189
To the nearest degrees, this is 59 degrees

Find the value of each variable. Assume it is a 45 45 90 triangle. Round to the nearest tenth.
Answer:
x = 6
y = 45 degrees
Step-by-step explanation:
Here, we want to get the measure of x and y
For a 45-45-90 triangle, the measure of each of the internal angle asides the right angle is 45 degrees
This mean y is 45
To get x, we know we have an isosceles triangle
So the length of the third ungiven leg is x too
Mathematically, the square of the hypotenuse (side facing the right angle) is equal the sum of the squares of the two other sides
(6 √2)^2 = x^2 + x^2
72 = 2x^2
x^2 = 72/2
x^2 = 36
x = √36
x = 6
