The equation for the Volume of a Sphere is:
V = [tex]\frac{4}{3}[/tex]πr²
V= volumer = radiusYou have been given the radius of 4.5 cm, so all you have to do is plug this information into the equation and solve!
V = [tex]\frac{4}{3}[/tex]π(4.5)²
↓
V = [tex]\frac{4}{3}[/tex]π × 20.25 or V= [tex]\frac{4}{3}[/tex] × 20.25π
↓
V= 27π (plug this into your calculator to get your numerical value)
V≈ 84.82
What is the equation of the line in slope intercept form that has a slope of 1/2 and passes through (2,3)
Answer:
y = 1/2x + 2
*view the attached graph to double check the answer*
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
y = mx + b
y = 1/2x + b
(2, 3) ==> substitute the numbers into the equation
y = 1/2x + b
3 = 1/2(2) + b
3 = 1 + b
-1 -1
2 = b
Our final equation: y = 1/2x + 2
Check your answer using (2, 3):
y = 1/2x + 2
3 = 1/2(2) + 2
3 = 1 + 2
3 = 3
This statement is correct

During science class, Jack, Jeff, and Jill measure the length of their bean sprouts. Jeff’s sprout is 0.9 times the length of Jack’s, and Jill’s is 1.08 times the length of Jack’s. Whose bean sprout is the longest?Why?
Answer:
Jill's is the longest.
if jeffs is 0.9 times the length of jacks, his is lesser than jacks. e.g. 2×0.9=1.8. Jeff's will always be shorter. since we know Jacks is over 1, Jill's will always be taller because 2×1.08=2.16 or Jill's length.

Sorry for not answering it early I know this answer is probably useless for you now
Step-by-step explanation:
Ok, suppose we were to divide this figure into two parts figure 1 & 2
like this... the picture is goven above
So, we can clearly see that figure 1 is a square as it has equal dimensions
and figure 2 is a rectangle because it should given in ur question but this is the only way to find out the area
So in figure 1 the dimensions are already give that the square is 8mm and on the other hand in figure 2 it is a rectangle, here only length is given - 6mm but width is not given. To find out the width it's simple, since the base of figure 1and2 is 12mm and the base of figure 1 is 8cm we can subtract it to get there rest of the base that is the base of figure 2.
So we get,
Base of figure 2 = Total base - Base of figure 1 = 12mm - 8mm = 4mm
Now since we have the dimensions, we only have to find the area of those two figures and add both areas to get the total are of the whole figure.
Area of figure 1
Area of square = side*side = 8*8 = 64mm^2
Area of figure 2
Area of rectangle = length*breadth = 4*6 = 24mm^2
Total area of the figures
Area of figure 1 + Area of figure 2 = 64mm^2+ 24mm^2 = 88mm^2

Please help I don't understand!
Answer:
Interquartile Range = 71
Step-by-step explanation:
The interquartile range is the middle 50% of the data set. First you calculate the location of the 3rd quartile (75% of the data set) by computing:
LQ3 = (75/100)(n + 1) -> here n is the number of observations you have, so 15. You can now compute LQ3 = (75/100)(16) = 12
The data at location 12 of your data set is 170.
Now you compute the 1st quartile (25% of the data set):
LQ1 = (25/100)(16) = 4
The data at location 4 of your data set is 99.
The difference between the 3rd quartile (170) and the 1st quartile (99) is your interquartile range:
IQR = 170 - 99 = 71

A gallery planner creates a scale model of a gallery with a scale of 2 inches = 7feet. If the scale model of the gallery measures 24 inches long, how many feet long is the actual gallery?
Answer:
The width of the scale model is 33 inches.
Step-by-step explanation:
This question is solved making a relation with the scale model. In the scale, 3 inches are worth 11 real feet.hope this help you.if you need any more help let me now and I mite be abal to help you.
The actual gallery comes to be 84 feet long.
What is a scale factor?A scale factor is a factor by which the dimension of an object is enlarged or diminished.
Scale of 2 inches = 7feet.
So, a scale of 1 inch = 7/2 feet
So, scale factor =7/2
So, a scale of 24 inches = 24*scale factor= 24*7/2 = 84 feet
So, the actual length of the gallery = 84 feet
Therefore, the actual gallery comes to be 84 feet long.

Write an equation to determine how many pairs of shoes, p, Roger must sell in a day to meet his daily earnings goal.
Find the number of pairs of shoes he must sell to meet his daily earnings goal.

Are multiplication and division of unit fractions related? Describe the relationship you see.
note: PLEASE MAKE ANSWER LONG BC IT CANT BE SHORT
Answer:Multiplication and division both need to have a common denominator or else you would get an incorrect answer. Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators."
Hii
Yes! They are indeed related. When dividing fractions, we need multiplication. Say, for example. We need to multiply the reciprocal of the second fraction to the first. So. If we needed to answer a question like "2/4 divided by 1/2" We would need to find a common denominator. We find common denominators by multiplication. We can do this 2 ways. See below.
For one, we could multiply 2 and 4 to get 8.For two, we could see what 2 and 4 both multiply by. In this case 8.
Then we would need to divide 2 and 1.
1 can go into 2 twice. 1+1 is 2.Then we multipy to find our denominator (this is a example of using multiplication with divison). 2x4 is 8. So the fraction would be 2/8.Simplify.
Find the GCD (or HCF) of numerator and denominator GCD of 2 and 8 is 2Divide both the numerator and denominator by the GCD 2 ÷ 2 / 8 ÷ 2Reduced fraction: 1 / 4 Therefore, 2/8 simplified to lowest terms is 1/4.
Simplified you'd get 1/4.
(tip, once the numerator hits 1, you can no longer simplify)

A net of a square pyramid is shown below. 5.95 cm 5.1 cm What is the surface area, in square centimeters, of the pyramid.
Answer:
86.7
Step-by-step explanation:
L x W = 5.1 x 5.1 = 26.01
B x H ÷ 2 = 5.1 x 5.95÷2 = 15.1725
15.1725 x 4 = 60.69
60.69 + 26.01 = 86.7
The surface area of the square pyramid is 92 square centimeters.
The given figure is a square pyramid.
We have to find the surface area.
Surface area = a² + 2a√(a²/4 + h²)
a is 5.1 cm and h is height which is 5.95 cm.
Surface area = 5.1² + 2(5.1)√(5.1²/4 + 5.95²)
=26.01 + 10.2 √(26.01 /4 +35.4025)
=26.01+10.2 √6.5025+35.4025
=26.01+10.2√41.905

explain how the models in questions 4 and 5 are the same
Answer:
Hi!
So, for question 4, when you divide it by two, you can split it horizontally to make it 6 squares instead of 3 rectangles from the model of the 1/3, leaving 2 shaded squares and 4 unshaded squares. And since you're dividing it by 2, you only use 1 of the shaded squares.
For question 5, I made the one-half horizontal instead of vertical so you can easily overlap the 2 models when you multiply them. Similar to question 4, the model becomes 6 squares and the 2 models overlap on one square.
Hope this helps! :)
