A box has dimensions of 19 inches long, 1.7 feet wide, and 6 inches high. What is the volume of the box? The formula for the volume is V = l ⋅ w ⋅ h.
193.8 cubic inches (in3)
2325.6 cubic inches (in3)
1.35 cubic inches (in3)
16.15 cubic inches (in3)
Answers
1 foot = 12 inches
1.7 feet = 1.7 * 12 = 20.4 in
The formula for the volume is:
V = l * w * h
and: l = 19 in, w = 20.4 in, h = 6 in.
V = 19 in * 20.4 in * 6 in = 2,325.6 in³
Answer: B ) 2,325.6 in³

Rita bought fabric and ribbon from a store the ribbon cost $18.50 rita paid the cashier $50.00 and received change of $5.25 how much did the fabric cost
Answers
2. I know this because...
- First, I subtracted the cost of the ribbon from how much she paid.
· Equation: $50.00 - $18.50 = $31.50
- Second, I subtracted the change received by the reduced cost ($31.50)
· Equation: $31.50 - $5.25 = $26.25
3. So, the final amount of money Rita spent on fabric is $26.25.

which of the following best describes a regular polygon when the sum of its interior angles is 1080 degrees A.) octagon B.) heptagon C.) hexagon D.) nonagon
Answers
1080= (n-2)180
1080/180=6
6=(n-2)
n=8
(This is the formula for finding the sum of interior angles in polygons. n represents the number of sides in the polygon)
Answer:
Option A is correct.
Step-by-step explanation:
Given: Sum of all the interior angles of a regular polygon = 1080°
To find: number of sides or name of polygon.
We know that Sum of all interior angle of a regular polygon is given by following formula,
Sum of all angles = ( n - 2 ) × 180° , where n = no of sides.
⇒ 1080° = ( n - 2 ) × 180°
n - 2 = 6
n = 6 + 2
n = 8
Name of regular polygon is Regular Octagon.
Therefore, Option A is correct.

Vincent is giving cakes to some children at a carnival. He has 2 strawberry cakes, 6 pineapple cakes, and 7 chocolate cakes. If Vincent selects a cake randomly without looking, what is the probability that he will give a pineapple cake to the first child and then a strawberry cake to the second child? (5 points)
6 over 15 multiplied by 2 over 14 is equal to 12 over 210
6 over 15 plus 2 over 14 is equal to 114 over 210
6 over 15 multiplied by 2 over 15 is equal to 12 over 225
6 over 15 plus 2 over 15 is equal to 8 over 15
Answers
2+6+7 = 15 total cakes
6 pineapple so probability is 6/15
then there would be 14 cakes
2 strawberry for a probability of 2/14
6/15 x 2/14 = 12/210
the first answer is the right one
Answer:
[tex]\frac{12}{210}[/tex]
Step-by-step explanation:
Strawberry cakes = 2
Pineapple cakes = 6
Chocolate cakes = 7
Total cakes = 15
Now we are given that Vincent selects a cake randomly without looking, and he will give a pineapple cake to the first child
So, probability of getting a pine apple cake in first draw = [tex]\frac{\text{No. of pineapple cakes}}{\text{Total no. of cakes}}[/tex]
= [tex]\frac{6}{15}[/tex]
Now total no. of remaining cakes = 15-1 =14
Now we are given that Vincent selects a cake randomly without looking, and he will give a strawberry cake to the second child
So, So, probability of getting a strawberry cake in second draw= [tex]\frac{2}{14}[/tex]
So, the probability that he will give a pineapple cake to the first child and then a strawberry cake to the second child = [tex]\frac{6}{15} \times\frac{2}{14} [/tex]
= [tex]\frac{12}{210}[/tex]
Hence Option A is true.
The probability that he will give a pineapple cake to the first child and then a strawberry cake to the second child is [tex]\frac{12}{210}[/tex]
You need to pump water out of a flooded basement, using two 50-gallon-per-minute (gpm) pumps. The basement has the dimensions shown and is flooded to a depth of 16 inches. How long will it take to pump the water out of the basement?
Answers
V = length x width x depth
length = 50 feet
width = 40 feet
depth = 16 inches ( 1 foot / 12 inches ) = 1.33 feet
V = 50 x 40 x 1.33 = 2666.67 ft^3 = 19948.05 gal
Time = V / rate
Time = 19948.05 gal / 100 gal / min
Time = 199.48 min
Find the outlier of the set of data: 24, 37, 33, 31, 28, 25, 33, 12
Answers
The outlier is therefore 12, because it is not in the general range of values, which is on average around 29.
Answer:
The outlier of the set is 12.
Step-by-step explanation:
Consider the provided set of data:
4, 37, 33, 31, 28, 25, 33, 12
The outlier is a kind of data which is abnormal distance from the other points.
Or the data that lies outside the other value in the provided set.
Now consider the data.
12 is lies outside the other values because the distance is abnormal.
The number 12 is not close to any of the other numbers.
Hence, the outlier of the set is 12.
In a rain forest, it typically rains 290 days out of the year. If it rains today, what is the probability that it will rain tomorrow?
a. 72%
b. 81%
c. 79%
d. 61%
Answers
Since we weren't given any probabilities based on the chance of rain after it rained the day before, we can assume the probability will stay the same. We can disregard "If it rains today...".
If it rains 290 days out of the year (365 days), there will be a 290/365 chance of rain of a particular day. You can divide 290 by 365 to get a 79% chance.

Answers
i) 2x + 2y = 8
ii) x + y = 4
use equation ii) to write y in terms of x as : y=4-x,
substitute y =4-x in equation i):
2x + 2y = 8
2x + 2(4-x) = 8
2x+8-2x=8
8=8
this is always true, which means the equations have infinitely many common solutions.

Which number in the monomial 215x18y3z21 needs to be changed to make it a perfect cube?
3

215
Answers
xyz = (x)(y)(z)
if x, y and z are perfect cubes, then xyz would also be a perfect cube
Also,
(x^n)^m = x^(mn)
if it is a perfect cube, then it can be factored into the expression (x^n)^3, wherein n is a whole number.
All should be a perfect cube, given
215x^18(y^3)(z^21)
By writing the terms separately, we would see which one is to be changed.
215 = 5*43, we see this is not a perfect cube, we could changed it to 6^3 or 216
x^18=(x^6)^3
y^3=y^3
z^21=(z^7)^3
The other terms are perfect cubes except for the first one. So the correct answer would be the last option, 215 should be changed.
