To find the volume of this triangular prism we should the formula base times height equals volume. Let’s say the base of the prism is the triangle. We need to find the area of the triangle so we can use the formula base times height divided by two. The base of the triangle is 5 and the height is 9. So 9x5=45 and then we divide this number by 2.
45/2 is 22.5m
So now we have the base for our formula and now we need the height. We can see 10m stretched across the prism so we can assume that is our height.
So we take our base (22.5m) and multiply it by out height (10m) to find our volume.
22.5 x 10 = 225
So the volume is 225m

s - c = 10
2s – 5c = 540
c - s = 10
2c + 5s = 540
S + c= 540
2s - 5c = 10
c - s = 10
5c + 2s = 540
Answers
multiply quantity of each and add them together to get total of 540
2s + 5c = 540 or 5c + 2s = 540
The difference in pages is 19 so you would subtract: c-s = 10
answer would be

Answers
A root of f(k) is x=k. Option C is correct.The numbers we're multiplying are factors of the product since they're divisible by it.
What is a factor?A number is obtained by dividing another number by itself without leaving a leftover. To put it another way, if multiplying two whole numbers produces a product,
The factor of the f(x) is given as;

So In the question we are given ,
Base of square = 4.5 cmHeight of pyramid = 5 cmWe know that in pyramid length and width are equal to base of a square . Therefore ,
Length of pyramid = 4.5 cmWidth of pyramid = 4.5 cmFormula :[tex] \rightarrow \blue{\boxed{ \sf{Volume \: of \: pyramid = \frac{lwh}{3} }}}[/tex]

When multiplying by 10s, the decimal point moves. Since it is a fraction, making it lesser than an actual 10, the decimal point moves one space to the left (instead of right)
437.683
Take away 430 because we don't need it for this step

The resistance of a wire varies directly with its length and inversely with the square of its diameter. If 100 feet of wire with diameter 0.01 inch has a resistance of 10 ohms, what is the resistance of 140 feet of the same type of wire if its diameter is 0.01 inch
Answers
Answer:
14 ohms
Step-by-step explanation:
The resistance varies directly with length, so increasing the length by a factor will increase the resistance by the same factor.
__
The length of the wire increased by a factor of 1.4 from 100 ft to 140 ft. That means the resistance will increase by a factor of 1.4 from 10 ohms to 14 ohms. (The diameter did not change.)
The longer wire will have a resistance of 14 ohms.

Rhys will tile the rectangle below to find it’s area. Q: How many unit squares with side length 1/10 foot will Rhys use to tile the rectangle? The sides of the rectangle: 3/10 foot and 4/5 foot. Answers: 24 unit squares, 18 unit squares, 12 unit squares, and 7 unit squares.
Answers
Using the areas of the rectangle and of the square, it is found that 24 unit squares will be used to tile the rectangle.
What is the area of a square?
The area of a square of side l is given by the square of l, that is:
A(l) = l².
In this problem, we have that [tex]l = \frac{1}{10}[/tex], hence the area is given by:
[tex]A = \left(\frac{1}{10}\right)^2 = \frac{1}{100} = 0.01[/tex]
What is the area of a rectangle?The area of a rectangle of length l and width w is given by the multiplication of the measures, that is:
A = lw.
In this problem, we have that the measures are:
[tex]l = \frac{3}{10}, w = \frac{4}{5}[/tex]
Hence:
[tex]A = lw = \frac{3}{10} \times \frac{4}{5} = \frac{12}{50} = \frac{24}{100} = 0.24[/tex]
The area of the rectangle is 24 times the area of the square, hence 24 unit squares will be used to tile the rectangle.

How to calculate the area of plane shapes?A square is a plane shape with 4 sides
The formula for calculating the area of the square is expressed as:
A = l^2
Given
side length of a square = 1/10 foot
A = (1/10)² = 1/100 = 0.01 square foot
Determine the area of the rectangle
Area = length * width
Area = 3/10 * 4/5
Area = 12/50 = 6/25
Area = 0.24 square foot
Take the ratio of both areas
Ratio = 0.24/0.01
Ratio = 24 units
Hence the number of unit squares with a side length of 1/10 foot that Rhys uses to tile the rectangle is 24 units
