Volume is a cubic measurement.
Set up a ratio of volume to the ratio of the height:
100/v2 = 2^3/5^3
V2 = 100 x 5^3/2^3 = 100 x 125/8 = 1,562.5 cubic feet
The volume of large pyramid is 1,562.5 cubic feet, by using ratio of heights.
Volume of pyramid based problem:What information do we have?
Ratio of heights of two similar pyramids = 2:5
Volume of smaller pyramid = 100 cubic feet
Volume of smaller pyramid / Volume of large pyramid = Height of smaller pyramid³ / Height of large pyramid³
100 / Volume of large pyramid = 2³ / 5³
Volume of large pyramid = 125(100) / 8
Volume of large pyramid = 1,562.5 cubic feet

Answer: 1.C 2.B
Step-by-step explanation:
Pls help and show workings
Due ASAP
Answer: B
Step-by-step explanation:
The equation [tex]y+2=\frac{3}{4} x-8[/tex] is not yet in slope-intercept form([tex]y=mx+b[/tex]). Simply subtract 2 from both sides to turn the equation into slope intercept form as [tex]y=\frac{3}{4}x-10[/tex]. For a line to be perpendicular to another, it must have an opposite reciprocal slope. A reciprocal is the fraction reversed, where the numerator is the denominator and vice versa. Thus, 3/4 would become 4/3. The opposite reciprocal of 3/4 would be -4/3.
The slope of the line given is 3/4. Thus, simply plug in the opposite reciprocal of 3/4 for the slope to get: [tex]y=-\frac{4}{3} x+b[/tex]. Then, because the line passes through -12, 1, plug those values in for x and y, respectively.
[tex]1=-\frac{4}{3}*-12+b[/tex]
[tex]1=16+b[/tex]
[tex]-15=b[/tex]
Thus, the equation of the line is [tex]y=-\frac{4}{3} x-15[/tex], or B.

Answer:
The mean absolute deviation of the data set is 2.5
Step-by-step explanation:
We need to find mean absolute deviation of the data set:
10,8,10,6,6,2,10,4
First we will find mean of the given data set.
The formula used is: [tex]Mean=\frac{Sum\:of\:all\:data}{Number\:of\:data}[/tex]
Sum of all data = 10+8+10+6+6+2+10+4 = 56
Number of data = 8
So, mean will be:
[tex]Mean=\frac{Sum\:of\:all\:data}{Number\:of\:data}\\Mean=\frac{56}{8}\\Mean=7[/tex]
Now, we will calculate the absolute difference between mean and each data value.
|10-7| = 3
|8-7| = 1
|10-7| = 3
|6-7| = |-1| = 1
|6-7| = |-1| = 1
|2-7| = |-5| = 5
|10-7| = 3
|4-7| = |-3| = 3
Now, we will find mean of 3,1,3,1,1,5,3,3
Sum of all data = 3+1+3+1+1+5+3+3 = 20
Number of data = 8
So, mean will be:
[tex]Mean=\frac{Sum\:of\:all\:data}{Number\:of\:data}\\Mean=\frac{20}{8}\\Mean=2.5[/tex]
So, the mean absolute deviation of the data set is 2.5
Problem
Jun used 56\,\text{cm}56cm56, start text, c, m, end text of ribbon to go around the edge of a rectangular lid. The lid was 13\,\text{cm}13cm13, start text, c, m, end text long.
What is the width of the lid?
Answer:
The width of the lid is 15 cm
Step-by-step explanation:
The Perimeter of a Rectangle
Given a rectangle of width W and height H, the perimeter is calculated as:
P = 2(W + L)
Jon used 56 cm of ribbon to go around the edge of a rectangular lid. This means the perimeter is:
2(W + L) = 56
Dividing by 2:
W + L = 28
Since the lid was L=13 cm long, the width is:
W = 28 - 13 = 15
The width of the lid is 15 cm
Felix bought a new pair of pants for $27.98. If the sales tax is 6%, how much did he spend in total?

Answer:
7200
Step-by-step explanation:
Find the exponents first.
10^3 = 1000
10^2 = 100
So..
7 x 1000 + 2 x 100
Do the multiplication first (BEDMAS - Brackets Exponents Division Multiplication Addition Subtraction).

Use the number line below, where RS = 6y + 3, ST = 4y + 7, and RT = 60.
Answer:
Step-by-step explanation:
RS + ST = RT
6y + 3 + 4y + 7 = 60
6y + 4y + 3 + 7 = 60
10y + 10 = 60
10y = 60 - 10
10y = 50
y = 50/10
y = 5
RS = 6*5 + 3 = 30 +3 = 33
ST = 4*5 + 7 = 20 + 7 = 27
Step-by-step explanation:
[Diagram in image attached]
RS + ST = RT
(6y +3) + (4y + 7) = 60
6y + 3 + 4y + 7 = 60
10y + 10 = 60
10y = 60 - 10
10y = 50
y = 50/10
y = 5
RS = 6y +3 = 6(5) + 3 = 30 + 3 = 33
ST = 4y +7 = 4(5) + 7 = 20 + 7 = 27
RT = 60
{RS + ST = RT
33 + 27 = 60}

Factorise
121ײ + 110 +25 y²
Answer:
(5y+11)²
Step-by-step explanation:
The given expression is :
25y²+110y+121
We need to factors of the given expression.
We know that, (11)² = 121
5² = 25
We can write the given expression as :
25y²+110y+121 = (5y)² + 2(5y)(11) +11²
Using identity : (a+b)² = a²+2ab+b²
25y²+110y+121 = (5y+11)²
Hence, the factors of 25y²+110y+121 is (5y+11)².

Calculate the area of the square shown below.
its a square ■ and on the bottom its 3.1 yd what do I do?
Step-by-step explanation:
area of square is a^2
3.1yd^2=9.61yd^2
Answer:
Area = 9.61^2
Step-by-step explanation:
A square has all equal sides so each side is the same length. To find the area mulyiply the length by the width. Since it is a square both sides will be 3.1 yds long. So multiply 3.1 by 3.1 and you will get 9.61^2, That is the area of the square.
Researcher were testing out a new antibiotic on a certain bacteria. They started with 38,000 bacteria. After one treatment with antibiotics, 33,820 were left. After a second treatment, 30,100 bacteria were left. How many bacteria will be left on day 27
Answer:
1836 bacteria
Step-by-step explanation:
Now the data is a progression; 38,000, 33,820, 30,100 .........
We can find out what type of progression it is, in this case, we can see that it is a geometric progression because;
r= 33,820/38,000 = 30,100/33,820 = 0.89
So, for a geometric progression;
Un = ar^n-1
Where;
a = 38,000
r = 0.89
n = 27 days
Un = ???
Un = 38,000 * (0.89)^27 - 1
Un = 1836 bacteria
Felix joined a local recreation center to play basketball the recreation center try to a $20 annual fee plus an additional $15 per month for usage of basketball courts feel like pre-pays by writing a check for $185 for how many months did Felix pay
Answer: Felix paid for 11 months.
Step-by-step explanation:
Let x = Number of months
Given: Annual fee = $ 20
charge per month = $15
Total amount = Annual fee + (charge per month) x (number of months)
[tex]\Rightarrow\ 185 = 20+15x\\\\\Rightarrow\ 165=15x\\\\\Rightarrow\ x = \dfrac{165}{15}\\\\\Rightarrow\ x =11[/tex]
Hence, Felix paid for 11 months.
Ocean water freezes at about -2 1/2 so silly fresh water freezes at zero anti-freeze a liquid used in radiators of cars freeze at -64 imagine if the temperature has dropped to the freezing point for ocean water how many degrees more most the temperature Drop for the anti-freeze to turn solid
Answer:
Temperature needs to drop by 61.5°
Step-by-step explanation:
Given that:
Freezing temperature of ocean water = - 2.5
Freezing temperature of fresh water = 0
Freezing temperature = anti-freeze = - 64
If temperature has dropped to freezing point for ocean water, then current temperature = - 2.5
How many more degrees must the temperature drop for temperature to turn solid :
Freezing temperature of anti-freeze - current temperature
-64 - (-2.5)
-64 + 2.5
-61.5
-61.5(the temperature needs to drop by 61.5°)
