What is the volume of a square pyramid with base side length of 22 cm and height of 8cm?
Answer:
Volume of a pyramid is
[tex] \frac{1}{3 } \times (area \: \: of \: base) \times height[/tex]
Since it's a square pyramid the base is a square
So we have
Area of a square = l²
where l is the length of one side
Area of square = 22²
= 484 cm²
So volume of the pyramid is
[tex] = \frac{1}{3} \times 484 \times 8 = 1290.7 {cm}^{3} [/tex]
Hope this helps you
the square root of 5 is
Step-by-step explanation:
The square root of 5 can be approximately found by doing the square root of 4 to get 2, and the square root of 9 to get 3. Then, because 5 is closer to 4 than 9, the square root of 5 is about 2.2.
Otherwise, simply do sqrt(5) in a calculator to get 2.23606798

Step-by-step explanation:
does the table represent a function why or why not?
Answer:
Yes, because each x-value corresponds to one y value.
Step-by-step explanation:
If you look at the table, you notice that there is one output (y) for every input (x). This means that it is a function. It would NOT be a function if you had two outputs for an input. For example, there are two x values that are 6. For one coordinate pair, the table says (6,9) and (6,8). Since there are two values for the same input- it wouldn't be a function. In this case, there is an input of 4 and 5 with the same output. That is okay! Even though they have the same y value, those inputs still only have ONE output.

solve the equation 2p square + 11p=30
Answer:
[tex]p=- \frac{15}{2}[/tex]
[tex]p=2[/tex]
Step-by-step explanation:
[tex]2p^2+11p=30[/tex]
Subtract 30 on both sides.
[tex]2p^2+11p-30=30-30[/tex]
[tex]2p^2+11p-30=0[/tex]
Factor left side of the equation.
[tex](2p + 15)(p-2)=0[/tex]
Set factors equal to 0.
[tex]2p+15=0[/tex]
[tex]2p=-15[/tex]
[tex]p=\frac{-15}{2}[/tex]
[tex]p-2=0[/tex]
[tex]p=2[/tex]

Earl worked 18 hours last week. If he had earned $2.00 an hour more but had worked only 15 hours, he would have earned the same amount. How much per hour does Earl earn? * A) $5.00 B) $10.00 C) $12.00 D) $15.00
Answer:
B) $10.00
Step-by-step explanation:
10 × 18 = 180
10 + 2 = 12
12 × 15 = 180
Answer:
B) $10.00Step-by-step explanation:
x - Earl's earnings per hour
The equation:
18x = 15(x + 2) use the distributive property
18x = (15)(x) + (15)(2)
18x = 15x + 30 subtract 15x from both sides
18x - 15x = 15x - 15x + 30
3x = 30 divide both sides by 3
3x : 3 = 30 : 3
x = 10
18x + 18 = 17 What is the variable x and how do you get that answer?
Answer:
x = - 1/18
Step-by-step explanation:
Move all terms not containing x to the right side of the equation
Divide each term by 18 and simplify
The result can be shown in multiple forms
x = -1/18
Decimal form= -0.05
Answer: x=-1/18
Step-by-step explanation:
18x+18=17
you subtract 18 from both sides
18x=-1
then you divide by 18 on both sides
x=-1/18
A builder wrote the measurements needed for a door.
height of door
2032 mm
width or door
Why did the builder write these measurements using millimetres instead of cm or m?
Answer:
Check the answer below.
Step-by-step explanation:
This is a very trivial but professional question. Note that all of millimetre, centimetre and metres are acceptable metric units but the millimetre is more preferable by builders and architects because:
1. It is easier to work with integer values on building and architectural plans, an advantage given by measuring and recording in millimetre.
2. working in millimetre allows for precision. The builder will record values that are very close to the true value
3. The measurement will be easily readable by anybody that sees it.
Suppose a company needs temporary passwords for the trial of a new time management software. Each password will have one digit, followed by one letter, followed by two digits. The digit 7 will not be used. So, there are 26 letters and 9 digits that will be used. Assume that the digits can be repeated. How many passwords can be created using this format?
Answer: 18954
Step-by-step explanation:
The given format for password : Each password will have one digit, followed by one letter, followed by two digits. The digit 7 will not be used. So, there are 26 letters and 9 digits that will be used.
We assume that the digits can be repeated.
Then by using fundamental principle of counting,
Number of passwords can be created = (Number of digits) x (Number of letters) x (Number of digits)x(Number of digits)
= 9 x 26 x 9 x 9
= 18954
Hence, Number of passwords can be created= 18954
A chef uses 12 cup of cheese for a small pizza. There are 6 grams of fat in 14 cup of cheese. Drag one expression next to each question. The correct expression for each row is a way to answer that question.
Answer:
I guess that we want to find how many grams of fat we have in a small pizza.
In a small pizza, we use 12 cups of cheese.
in 14 cups of cheese, we have 6 grams of fat.
Then, in 12 cups of cheese, we have x grams of fat.
We want to find the value of x.
We know that the ratio between the number of cups must be the same as the ratio between the grams of fat then:
12cups/14cups = x/6grams
x = (12/14)*6grams = 5.14 grams
Then in the 12 cups of cheese, we have 5.14 grams of fat.
which measure is of an angle that is conterminal with a 95 degree angle
Answer: Choice B
95 - 1080n for any integer n
=================================================
Explanation:
Notice how 1080 is a multiple of 360 since 360*3 = 1080. The other values 1450, 780 and 340 are not multiples of 360. For example 1450/360 = 4.02777 approximately. We need a whole number result to show it is a multiple.
Therefore, choice B shows subtracting off a multiple of 360 from the original angle 95. In my opinion, it would be better to write 95+360n or 95-360n to make it more clear we are adding or subtracting multiples of 360.
Choice B will find coterminal angles, but there will be missing gaps. One missing coterminal angle is 95-360 = -265 degrees. So again, 95-360n is a more complete picture. I can see what your teacher is going for though.

The equation for linear regression is of the form, Y = a + bX
The formula for the intercept, a, and the slope, b, are;
[tex]b = \dfrac{N\sum XY - \left (\sum X \right )\left (\sum Y \right )}{N\sum X^{2} - \left (\sum X \right )^{2}}[/tex]
[tex]a = \dfrac{\sum Y - b\sum X}{N}[/tex]
Where:
N = 4
∑XY = 1066
∑X = 46
∑Y = 87
∑X² = 644
(∑X)² = 2116
b = (4*1066 - 46*87)/(4*644 - 2116) = 0.5696
a = (87 - 0.5696*46)/4 = 15.1996
The standard deviation of the x- values
[tex]S_X = \sqrt{\dfrac{\sum (x_i - \mu)^2}{N} }[/tex]
[tex]\sum (x_i - \mu)^2}[/tex] = 115
N = 4
Sx =√(115/4)
Sx = 5.36
[tex]S_Y = \sqrt{\dfrac{\sum (y_i - \mu_y)^2}{N} }[/tex]
[tex]\sum (y_i - \mu_y)^2}[/tex] = 476.75
N = 4
Sy =√(476.75/4)
Sy= 10.92
b = r × Sy/Sx
Where:
r = The correlation coefficient
r = b × Sx/Sy = 0.5696*5.36/10.92 = 0.2796 ≈ 0.28
The correct option is 0.28.

Step-by-step explanation:
248 miles per hour = x meters per second. Round to the nearest hundredth.
Answer:
110.87 m/sStep-by-step explanation:
This problem is based on unit conversion from miles per hour to meter per second.'
From tables 1 mph= 0.44704 m/s
Given 248 mph to be converted to meters per second.
hence we have
1 mph= 0.44704 m/s
248 mph= x
cross multiplying we have
x= 110.86592 m/s
to the nearest hundreth we have
110.87 m/sThe marked price of a watch is 30% above the cost price. When it is sold allowing
20% discount on it, there is a gain of Rs 150. Find the marked price of watch.
Answer:
The marked price = Rs 4,475.
Step-by-step explanation:
Let the marked price of the watch = x
Let the cost price of the watch = y
The given information are;
The marked price of the watch = 30% above the cost price
The discount when it was sold = 20%
The gain when it was sold = Rs 150
Therefore, we have marked price = y + 30/100×y = y + 0.3·y = 1.3·y
The selling price with 20% discount is therefore, 1.3·y - 0.2×1.3·y
The selling price = 1.04·y
The gain = Selling price - cost price = 1.04·y - y = 0.04·y
Rs 150= 0.04·y
y = Rs 150/0.04 = Rs 3,750
Therefore, the marked price = 1.3×y = 1.3×3,750 = Rs 4,875
The marked price = Rs 4,475.
