Answer:
The length of each side is 8 square units
Step-by-step explanation:
This is because all sides of a square are the same and area is length times width. So, we can just find the square root of 64 which is 8.
The volume of this pyramid is 36.67 m3. If the area of its base is 10.0 m2, how high is the pyramid? Round to the nearest whole meter. a) 4 m b) 11 m c) 5m d) 12 m
Answer:
b
Step-by-step explanation:
A pyramid is a three-dimensional object. The base of a pyramid is a polygon. the top and the base of a polygon forms a triangle
The volume of a pyramid = 1/3 × (area of base x height)
volume = 36.67 m3
area = 10.0 m2,
height = ?
36.67 = 1/3 x (10 x h)
multiply both sides of the equation by 3
110.01 = 10h
divide both sides by 10
h = 11.0001 m
What is the area of the triangle?
15
18
units?
Answer:
135
Step-by-step explanation:
u multiply 18 by 15 then divide the answer by 2 and I got 135 :)
A survey of two communities asked residents which candidate they supported for a local election The survey data are shown in the relative frequency table. What percentage of the Cherry Hill residents polled supported Zhang ?
Answer:
about 48%
Step-by-step explanation:
I just took the quiz
The percentage of the Cherry Hill residents polled supported Zhang is 51.61%.
What is a percentage?
A percentage is a number or ratio that can be expressed as a fraction of 100. Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.
For the given situation,
The relative frequency table shows a survey of two communities asked residents which candidate they supported for a local election.
Candidates supported Zhang in Cherry hill = 0.32
Total candidates in Cherry hill = 0.62
Percentage of the Cherry Hill residents polled supported Zhang is
⇒ [tex]\frac{0.32}{0.62}(100)[/tex]
⇒ [tex]0.5161(100)[/tex]
⇒ [tex]51.61\%[/tex]
Hence we can conclude that the percentage of the Cherry Hill residents polled supported Zhang is 51.61%.

Step-by-step explanation:
Of flowers in a field 43% are yellow . The others are white. A bee randombly lands on a flowerdescribe the complelment of the bee landing on a yellow flower. Determine its probability
Answer:
0.43
Step-by-step explanation:
Yellow flowers are 43%.
White flowers are = (100% - 43% ) = 57%
Consider there are total 100 flowers in the garden , so yellow ones are 43 and white ones are 57
Probability of a bee landing on a yellow flower is 43 out of 100
= 43/ 100
=0.43

Wich point, when added to the set would form a relation that is not a function.
Please help.
Answer:
(4,2)
Step-by-step explanation:
A function is when an input only has one output. 4 already has an output of 6, when we add (4,2), then 4 will have two outputs. This will not be a function.

Can two angles be both vertical and adjacent? Explain why or why not?
Answer:
no then can not be both
Step-by-step explanation:
vertical angles require the intersection of 2 straight lines and then they are the opposite of where they intersect
adjacent are next to each other
Answer:
no, vertical angles can never be adjacent. adjacent angles are the ones next to each other while vertical angles are opposite from each other

Answer:
We have 15 Nickels and 10 Dimes.
Step-by-step explanation:
This is a system of equations! [Literally in a class reviewing that rn}
Lets make a chart:
Number of Coins x Value of Coin = Total Value
Dimes | d | 10 | 10d
Nickels | n | 5 | 5n
So, When you have a System of Equations with Money, One equations is about the value of the money, and the other about the number of coins.
The First Equation [Number of Coins]:
D + N = 25
the Second Equation [Value of Money]:
10D + 5N = 175
I will use Elimination to solve this, however, graphing and substitution works too.
ELIMINATION:
Multiply First equation by -5
-5[D + N = 25] = -5D - 5N = -125
Add the Two Equations vertically.
-5D - 5N = -125
10D + 5n = 175
---------------------
5D = 50
Divide both sides by 5.
5D/5 = 50/5
D = 10
Substitute D= 10 In any equation and solve for the other variable.
10 + N = 25
Subtract 10 from both sides.
10 - 10 + N = 25 - 10
N = 15
So, we have 15 Nickels and 10 Dimes.

What is the solution of (x+8)/(5x+-1)>0?
Answer:
the solution set is (-infinity, -8) ∪ (-8, 1/5)
Step-by-step explanation:
x + 8 changes sign at x = -8.
I'll assume you meant 5x - 1 (as 5x+- is meaningless). 5x - 1 changes sign at x = 1/5.
Subdivide the x-axis using the two x-values found above:
(negative infinity, -8), (-8, 1/5), (1/5, infinity.
Choose a representative value from each interval. I'm choosing x = -10, x = 0 and x = 1.
Now test the given inequality at each of these x-values. Is the result true or false?
x + 8
---------- > 0
5x - 1
For x = -10:
-10 + 8
--------------- > 0 => -2/(-51) => 2/51 This is TRUE
5(-10) - 1
For x = 1:
1 + 8
---------- > 0 => 9/4 This is TRUE
5 - 1
For x = 0:
8
---------- > 0 This is FALSE
- 1
Therefore the solution set is (-infinity, -8) ∪ (-8, 1/5)

How many one-inch cubes will fit in the box?
Answer:
D. 132,651 cubes
Step-by-step explanation:
You're looking for how many cubes fit in the box. Remember cubic means 3 dimensions and squared means 2 dimensions.
Use length x width x height and converting the 4.25 feet to inches...
4.25×12=51
51×51×51=132,651
Meaning 132,651 one inch cubes would fit.
Answer:
132,651 cubes
Step-by-step explanation:
4.25 ft = 51 inches
51 x 51 x51 = 132,651 inches
1 x 1 x 1 = 1 inch cubes
so
132,651 divided by 1 = 132,651.
the width of a rectangle is represented by 2x, and the length is represented by x2 ->
- x + 3. Which expression represents the area of the rectangle?
Answer:
x2 ->
Step-by-step explanation:
Width area = long edge × short edge
= (2+3x).(x-4)
= 2x-8+3x²-12x
= 3x²-8-10x
= 3x²-10x-8

For the following arithmetic sequence, find the value of a and d and hence find the term indicated: - 2 , 2 , 6 , 10 , . . . , t 7. If the first term of an arithmetic sequence is 7 and the 4th term is 28, find the value of d.
Answer:
[tex]t_{7}[/tex] = 22 is the answer to the first question
d = 4 is the answer to the second question
Step-by-step explanation:
use the formula [tex]a_{n} = a + (n - 1)d[/tex]
6 - 2 = 4 = d a = -2 n = 7
[tex]t_{7}[/tex] = -2 + (7 - 1)4
= -2 + 6(4)
= -2 + 24
= 22
use the formula [tex]a_{n} = a + (n - 1)d[/tex]
a = 7
n = 4
[tex]a_{4} = 28[/tex]
28 = 7 + (7 - 1)d
= 4 + 6d
24 = 6d
d = 4

Can someone tell me three events that have a probability of 0 (zero) and why?
Step-by-step explanation:
A probability of zero means things are impossible to happen.

Select the statement that describes the following expression 6 x (2 + 7) − 9.
A) 6 times the sum of 2 and 7, then subtract 9
B) 6 times the product of 2 and 7, then add 9
C) 6 times the difference of 2 and 7, then subtract 9
D) 6 times the sum of 2 and 7, then add 9
Answer:
A) 6 times the sum of 2 and 7, then subtract 9
Step-by-step explanation:
At the end of the given expression, there is a " - 9", which means that the 9 is getting subtracted. From this you can cancel out answer choices B and D because they add 9.
In the expression, there is a (2 + 7), which means that the 2 and the 7 are being added together, producing a sum. That cancels out answer choice C, leaving choice A.
Answer:
Step-by-step explanation:
Order of operation rules require that we do all work inside parentheses first, and then multiplication/division, and only then addition and subtraction.
We evaluate (2 + 7) first, obtaining 9, and then have 6·9 - 9.
This multiplication must be done before the subtraction, so we get:
54 - 9 = 45 This corresponds to Answer A.
The box plot summarizes the number of goals scored at a basketball game. State the least

HA

Number of Goals
Median
Upper Quartile:
Lower Quartile: I
Interquartile Range:
Answer:
Median: 25
Upper quartile: 30
Lower quartile: 20
IQR: 10
Step-by-step explanation:
The nice thing here is they already put them in order :)
16, 18, 20, 22, 24, 26, 28, 30, 32, 34
For the median, it's the middle number of the ordered data set. Unfortunately here, there is an even number of entries. In that case, we average the middle two numbers, 24 and 26. 24 + 26 = 50/2 = 25
For lower quartile/Q1, you take the middle number of the bottom half of the data set. Bottom half: 16, 18, 20, 22, 24...so the middle is 20
For the upper quartile/Q3, you take the middle number of the top half of the data set. Upper half: 26, 28, 30, 32, 34...so the middle is 30
For interquartile range/IQR, you calculate the range from third to first quartile: 30-20 = 10
