One of the legs is its base and the other is its height. (The longest side is the hypotenuse!)
The area of the triangular base is bh/2 = (9)(12) / 2. There are two of these.
There are also three rectangular sides on the prism.
Their dimensions are 9 by 20, 12 by 20, and 15 by 20.

If you can walk 3 1/3 miles in an hour, how many miles can you walk in 30 minutes, given the
same pace?
Answers
Answer:
d = 1.67 miles
Step-by-step explanation:
Given that,
Speed of a person, [tex]s=3\dfrac{1}{3}\ mph[/tex]
We need to find how many miles can you walk in 30 minutes, given the same pace.
30 minutes = 0.5 h
[tex]3\dfrac{1}{3}\ mph = \dfrac{10}{3}\ mph[/tex]
Speed = distance/time
[tex]d=v\times t\\\\d=\dfrac{10}{3}\ mph\times 0.5\ h\\\\d=1.67\ miles[/tex]
So, the person will cover a distance of 1.67 miles

janesa has 24 coins in her pocket worth exactly $1.00. she tells her younger brother jackson that he can have the coins if he correctly guesses how many of each coin she has. she gives him the hint that there are only nickels and pennies. complete the equation that represents the total value of the nickels and p pennies 5( blank ) + p = 100
Answers
Answer:
Number of Nickels = 19
Number of pennies = 5
Step-by-step explanation:
The type of coins that Janessa has = nickels and pennies.
Janessa has a total number of 24 coins
The sum of the nickels and pennies = $1.00
Let us represent the number of nickels as x
The number of pennies as y
Hence, our system of equations is :
x + y = 24..... Equation 1
x = 24 - y
A nickel is worth 5 cents.
1 nickel = $0.05
A penny is worth 1 cent.
1 penny = $0.01
Therefore,
$0.05× x + $0.01 × y= $1.00
0.05x + 0.01y = 1.00........Equation 2
Substitute 24 - y for x in Equation 1
0.05(24 - y) + 0.01y = 1
1.2 - 0.05y + 0.01y = 1
1.2 - 1 = 0.05y - 0.01y
0.2 = 0.04y
y = 0.2/0.04
y = 5
We have 5 pennies
x = 24 - y
x = 24 - 5
x = 19
We have 19 nickels

The faculty senate at a large university wanted to know what proportion of the students thought foreign language classes should be required for everyone. The statistics department offered to cooperate in conducting a survey, and a simple random sample of 500 students was selected from all the students enrolled in statistics classes. A survey form was sent by email to these 500 students. True or false
Answers
Answer:
True
Step-by-step explanation:
This is because, since the number of students who would engage in the survey is very much (around 500 students), the best option would be to send the survey form to them in their various email. This makes things easier for them to be able to respond to it.
The FIFO method of computing equivalent units excludes the beginning inventory costs in computing the cost per equivalent unit for the current period.
Answers
Answer:
Yes
Step-by-step explanation:
The FIFO method of process costing assumes that the opening work in process is the first group of units to be processed and completed during the current period. The opening work in progress is charged separately to completed production and the cost per unit is based only on the current period costs and the production for the current period. The closing work in process is assumed to come from the new units started during the period.
Please explain step by step how you will answer the equation 4(x+6)-11= 25. You

Answers
Answer:
x=3
Step-by-step explanation:
4(x+6)-11= 25
Distribute the 4: 4x+24-11=25
Add the 11 on both sides: 4x+24=36
Subtract 24 from both sides: 4x=12
Divide 12 by 4 to isolate x: x=3

A 2-column table with 3 rows. Column 1 is labeled Minutes with entries 6, 14, 20. Column 2 is labeled Blocks with entries 3, 7, 10.
Does the table represent a proportional relationship?
A Yes, because both columns are written in ascending order.
B Yes, because the values in the second column are less than the values in the first column.
C Yes, because the ratios are equivalent between each pair of values.
D No, because the values in the table do not increase by the same amount in each row.
Answers
Answer:
C. Yes, because the ratios are equivalent between each pair of values.
Step-by-step explanation:
A relationship between two quantities is proportional if the ratio of the two quantities are the same for all the given possible pairs of values.
In the table given, the ratio of block to mins in the first given pair of values is 3/6 = 3/6 = ½.
In the second given pair, it is 7 to 14 = 7/14 = ½. The same ratio is gotten for the others as well.
Therefore, the table represents a proportional relationship.
The answer is: "C. Yes, because the ratios are equivalent between each pair of values."

A study is designed to determine whether grades in a statistics course could be improved by offering special review material. The 250 students enrolled in a large introductory statistics class are also enrolled in one of 20 lab sections. The 20 lab sections are randomly divided into two groups of 10 lab sections each. The students in the first set of 10 lab sections are given extra review material during the last 15 minutes of each weekly lab session. The students in the remaining 10 lab sections receive the regular lesson material, without the extra review material. The grades of the students who reviewed weekly were higher, on average, than the students who did not review every week. What type of study is this
Answers
Answer:
Experimental but not double-blinded study
Step-by-step explanation:
The type of study being described is an Experimental but not double-blinded study. That is because it is a study that has a control group, dependent variable, and an independent variable all used in order to acquire specifically targetted data from the results that are derived from the experiment itself. Also since the scientists/researchers know exactly which lab sections are getting the extra review material (independent variable), then that makes this a non-double-blinded study.

find the measure of an interior angle of a regular polygon that has 10 sides
Answers
Answer: The sum of the measures of the interior angles of a decagon (10 sided polygon) is 1,440. We found this by using the formula (n-2)(180). Thus, to find the measure of each interior angle we simply divide the sum by the number of total sides in the polygon. 1,440/10 = 144.

Explain how to find the greatest number of identical arrangements that can be made with 54 roses and 42 tulips with no flowers left over then u got to show ur work
Answers
Answer:
The greatest number of identical arrangements is 6 units of 9 roses and 7 tulips each.
Step-by-step explanation:
Tulips represent the limiting quantity. In this case, the easiest and most effective approach is determining the ratio of roses to tulips to get how many roses must be left along with a minimum quantity of tulips in a unit. That is:
[tex]x = \frac{54\,roses}{42\,tulips}[/tex]
[tex]x = \frac{27\,roses}{21\,tulips}[/tex]
[tex]x = \frac{9\,roses}{7\,tulips}[/tex]
The greatest number of identical arrangements is 6 units of 9 roses and 7 tulips each.

Please help me out. A square has an area of 90 square inches. Which two consecutive integers does a side length of the square fall between?
The side length of a square with an area of 90 square inches falls between the integers
A and
B .
Answers
Answer:
9 and 10
Step-by-step explanation:
Area of a square = s², where s = side length
Given that the square has an area of 90 in², the side length (s) of the square = √90.
Thus, 90 is not a perfect square and it's square root won't give us an integer.
Thus, √90 lies between two perfect squares namely, 81 and 100.
Therefore, the side length of the square would be:
√81 < √90 < √100
9 < √90 < 10.
The side length of the square lies between 9 and 10.

Ralph chase plans to sell a piece of property for 170000 he wants the money to be paid off in two ways -a short-term note at 11% interest and a long term note at 9% interest. Find the amount of each note if the total annual interest paid is 171700
Answers
Answer:
There is something wrong with the question because you cannot earn more interest during a year than the principal if you earn only 9% or 11%. You would have to earn more than 100%, so I will do this calculation based on $17,170 (not $171,700) earned in interest per year.
let S = amount received from short term note, and L = amount received from long term note
0.11S + 0.09L = 17170
S + L = 170000
S = 170000 - L
0.11 (170000 - L) + 0.09L = 17170
18700 - 0.11L + 0.09L = 17170
1530 - 0.02L = 0
1530 = 0.02L
L = 1530 / 0.02 = $76,500
S = 170000 - 76500 = $93,500
