Area of base of a triangular pyramid = 9 inches
Length of height of triangular pyramid = 10 inches
We know that :
[tex]\tt \: \color{hotpink}volume\: of \: a \: triangular \: pyramid \color{plum}= \frac{1}{3} Bh[/tex]
Which means :
Volume of this triangular pyramid :
[tex] = \tt \frac{1}{3} \times 9 \times 10[/tex]
[tex] =\tt \frac{9 \times 10}{3} [/tex]
[tex] =\tt \frac{90}{3} [/tex]
[tex]\color{plum} =\tt 30 \: {inches}^{3} [/tex]
Thus, the volume of this pyramid = 30 inches³

Write the equation for the line that passes through (3,0) and is
parallel to the line 2x + 5y = 30.
Answers
Answer:
2x + 5y = 6
Step-by-step explanation:
The equation of a line parallel to 2x + 5y = 30 has exactly the same form as does 2x + 5y = 30, but the constant is different. Starting with 2x + 5y = 30, replace the constant (30) with C, x with 3 and y with 0:
2(3) + 0 = C, so C = 6
Then the desired equation is 2x + 5y = 6

Nothing I can say about the homework
Answers
Here is something i found on the web.
Homework is your teachers' way of evaluating how much you understand of what's going on in class. But it can seem overwhelming at times. Luckily, you can do a few things to make homework less work.
Budget your time. If you don't finish your homework at school, think about how much you have left and what else is going on that day. Most high-school students have between 1 and 3 hours of homework a night. If it's a heavy homework day, you'll need to devote more time to homework. It's a good idea to come up with a homework schedule, especially if you're involved in sports or activities or have an after-school job.

Answer:
3 pieces
Step-by-step explanation:
Given: Figure
To find: Number of 8.5 in. × 11 in. pieces used to cover the floors of a room and a hallway in her dollhouse
Solution:
In the given figure, AC = 22 in.
AB + BC = 22 in.
AB + EF = 22 (As BC = EF being opposite sides of rectangle)
AB + 10 = 22
AB = 22 - 10 = 12 in.
Area of rectangle ABGH = AB × AH = 12 × 5 = 60 square inches
(area of rectangle = length × breadth )
CE = CD + DE = AH + GF (As CD = AH and DE = GF)
CE = 5 + 15 = 20 inches
Area of rectangle BCEF = BC × CE = 10 × 20 = 200 square inches
(BC = EF = 10 in.)
Total area of the figure = Area of rectangle ABGH + Area of rectangle BCEF = 60 + 200 = 260 square inches
Area of pieces of felt = 8.5 × 11
So,
Number of pieces required = Total area of the figure / Area of pieces of felt = 3 pieces

A phone company charges $67 for monthly access and $14 for each gigabyte of data used. If you sign a two-year contract and use 147.5 gigabytes of data, what is the total amount you will pay for phone service?
Answers
Answer:
the answer is below :)
Step-by-step explanation:
BigBytes will be 100 +10x = y ($100 flat fee plus 10 times the number of gigabytes equals total cost).
GoGig will be 120 + 5x = y. ($120 flat fee plus 5 times the number of gigabytes equals total cost).
Now set them equal to each other and solve for x to find where the gigabytes are the same.
100 + 10x = 120 + 5x
Subtract 100 from both sides: 10x = 20 + 5x
Subtract 5x from both sides: 5x = 20.
Divide both sides by 5: x = 4. 4 gigabytes is the answer.
a brainliest would be appreciated :)
The total amount you will pay for phone service is 4 gigabytes.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
BigBytes will be 100 +10x = y
Therefore , We have $100 flat fee plus 10 times the number of gigabytes equals total cost).
GoGig will be 120 + 5x = y.
We have $120 flat fee plus 5 times the number of gigabytes equals total cost).
Now set them equal to each other and solve for x;
100 + 10x = 120 + 5x
Now Subtract 100 from both sides:
10x = 20 + 5x
Then Subtract 5x from both sides:
5x = 20.
Now Divide both sides by 5:
x = 4.
Hence, the total amount you will pay for phone service is 4 gigabytes.

A girl jogs around a track for 45 minutes. How far does the girl jog if she travels at a speed of 0.15 m/min?
help quick
Answers
Answer:
6.75 m
Step-by-step explanation:
Time = 45 mins
Speed = 0.15 m/min
Distance = Speed * time
Distance = 0.15 m/min * 45 mins = 6.75 m
Answer:
6.75m
Step-by-step explanation:
We know that she jogged for 45 minutes and was going around 0.15m/min so we can multiply her distance per minute (0.15m/min), by the number of minutes(45min).
If we use Long Multiplication also known as Standard Algorithm it should look like this:
We have to multiply 0.15 x 100 or move the decimal two spaces
Once you get your answer (675) just move the decimal 2 spaces forward or divide by 100. You should get 6.75, and now just add your label (m)

exponential growth function is f(t)=Pe^(rt)
where P is starting value, or price

What is unit rate?There is an independent quantity, and a quantity that depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called the rate of increment of dependent quantity per unit increment in independent quantity.
We have been given 100 cars pass by in 2 hours
We need to find the unit rate.
Total car = 100
Time = 2 hours
Unit rate = 100/2
Unit rate = 50

15. Metal A has a density of 2.4g/cm3 and Metal B has a density of 1.8
g/cm3. Their masses are combined in the ratio 2:3 to make metal C which
has a mass of 60 grams. Find the density of the metal C*
Answers
Answer:
The density of the metal C is 2 g/cm³
Step-by-step explanation:
The parameters of the two metals are;
The density of the Metal A = 2.4 g/cm³
The density of the Metal B = 1.8 g/cm³
The ratio in which their masses are combined to make the metal C= 2:3
The mass of the metal C, m = 60 grams
Let, 'x', represent the mass of the metal A in the 60 grams of the metal C and let 'y' represent the mass of the metal B in the 60 grams of the metal C
Let the ratio of the metals A and B in the metal C = x:y = 2:3
Therefore;
The mass of the metal A in the metal C, x = (2/(3 + 2)) × 60 g = 24 g
The volume of the metal A in the metal C, V₁ = (24 g)/(2.4 g/cm³) = 10 cm³
The mass of the metal B in the metal C, y = (3/(3 + 2)) × 60 g = 36 g
The volume of the metal B in the metal C, V₂ = (36 g)/(1.8 g/cm³) = 20 cm³
The volume of the metal C, V = V₁ + V₂ = 10 cm³ + 20 cm³ = 30 cm³
The density of the metal C = ρ = m/V
ρ = (60 g)/(30 cm³) = 2 g/cm³
The density of the metal C, ρ = 2 g/cm³
