What is the volume of a sphere with a radius of 24.2 ft, rounded to the
nearest tenth of a cubic foot?
Answer:
V is about 59335.5 cubic feet
Step-by-step explanation:
The formula to find the volume of a sphere is V=4/3πr^3.
If the radius is 24.2, we just need to substitute numbers into the equation.
V=4/3(3.14)(24.2^3)
V=4/3(3.14)(14172.488) **Find 24.2 cubed**
V=(4*14172.488)/3*3.14
V=(56689.952)/3*3.14 **Multiply the numerator**
V=18896.65067*3.14 **Divide the numerator by the denominator**
V=59335.48309 **Multiply by the simplified pi**
V is about 59335.5 cubic feet
It's a bit long of work but I hope I was able to have helped! Good Luck!
Answer:
The volume of given sphere is 59,335.5 cubic feet
Step-by-step explanation:
Given that
Radius of sphere=r= 24.2 feet
The volume of a sphere is calculated by the formula:
[tex]V = \frac{4}{3}\pi r^3[/tex]
We can use 3.14 or 22/7 for the value of pi
Putting the values, we get
[tex]V = \frac{4}{3} * 3.14 * (24.2)^3\\= \frac{12.56}{3} * 14,172.488\\=\frac{178,006.44928}{3}\\=59,335.48309[/tex]
Rounding off to nearest tenth of cubic feet
59,335.5 cubic feet
Hence,
The volume of given sphere is 59,335.5 cubic feet

Answer:
D. [tex]Rate = -\frac{49}{4}^{\circ} /\frac{7}{2}\ hr[/tex]
Step-by-step explanation:
Given
[tex]T_1 =0^{\circ}[/tex]
[tex]T_2 =-12\frac{1}{4}^{\circ}[/tex]
[tex]Time = 3\frac{1}{2}\ hr[/tex]
Required
Determine the change in temperature per hour
This is calculated as:
[tex]Rate = \frac{T_2 - T_1}{Time}[/tex]
[tex]Rate = \frac{-12\frac{1}{4}^{\circ} - 0^{\circ}}{3\frac{1}{2}\ hr}[/tex]
[tex]Rate = \frac{-12\frac{1}{4}^{\circ} }{3\frac{1}{2}\ hr}[/tex]
Convert to improper fractions
[tex]Rate = \frac{-\frac{49}{4}^{\circ} }{\frac{7}{2}\ hr}[/tex]
Express as:
[tex]Rate = -\frac{49}{4}^{\circ} /\frac{7}{2}\ hr[/tex]
5. The 7th grade has 386 students. There are 32 more girls than boys in the grade.
How many boys are in the 7th grade?
Answer:
161 boys
Step-by-step explanation:
First you find the even amount of boys and girls out of 386
386 divided by 2 = 193
Then you subtract 32 boys and add the 32 to girls since there are 32 more girls than boys
(boys) 193 - 32 = 161
(girls) 193 + 32 = 225
So there are 161 boys and 225 girls
Jamie is an analyst at an education technology company. She gathered data on the results of a certain type of question. Of the 2,000 responses she looked at, 1,092 responded correctly. What equation could Jamie use to calculate the margin of error at a 90% confidence interval?
Answer:

3rd Square - 0.546
4th Square - 2000
(got it right on edmentum)
for better understanding of what I mean please take your time to look at the picture below↓Step-by-step explanation:
The margin of error for the 90% confidence interval with a probability of success of 0.546 is 0.0183.
What is the margin of error?The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.
Jamie is an analyst at an education technology company. She gathered data on the results of a certain type of question. Of the 2,000 responses she looked at, 1,092 responded correctly.
Then the value of p will be

And the z-value for the 90% confidence interval will be
[tex]\rm z = 1.645[/tex]
And N = 2000
Then the margin of error (ME) will be
[tex]ME = z \times \sqrt{\dfrac{p(1-p)}{N}}\\\\ME = 1.645\times \sqrt{\dfrac{0.546(1-0.546)}{2000}}\\\\ME = 0.0183[/tex]

the answer is in the question 1 inch (1/) is equal to 150 miles (/150)
1/150
The scale factor of 1 inch = 150 miles is 1/150.
Option D is the correct answer.
What is a scale factor?A scale factor is defined as the ratio between the scale of a new object and the scale of the original object,
We have,
1 inch = 150 miles
150 miles is the original dimension
1 inch is the new dimension
Now,
Scale factor.
= New dimension / Original dimension
= 1/150

Answer:
$37623.04
Step-by-step explanation:
The formula we'll use for this is the simple interest formula, or:
[tex]I=p*r*t[/tex]
Where:
P is the principal amount, $1088.00.
r is the interest rate, 839.5% per year, or in decimal form, 839.5/100=8.395.
t is the time involved, 4....year(s) time periods.
So, t is 4....year time periods.
To find the simple interest, we multiply 1088 × 8.395 × 4 to get that:
The interest is: $36535.04
Usually now, the interest is added onto the principal to figure some new amount after 4 year(s),
or 1088.00 + 36535.04 = 37623.04.
