The base is an equilateral triangle with an area of 6 square inches. the height of the pyramid is 15 inches. what is the volume
The volume of the pyramid is 30 inches cube.
How to find the volume of a pyramid?The base of the pyramid is an equilateral triangle with an area of 6 inches². The height of the pyramid is 15 inches.
Therefore, the volume of the pyramid can be calculated as follows:
volume of the pyramid = 1 / 3 BH
where
B = base areaH = height of the pyramidTherefore,
B = 6 inches²
H = 15 inches
Hence,
volume of the pyramid = 1 / 3 × 6 × 15
volume of the pyramid = 1 / 3 × 90
Therefore,
volume of the pyramid = 30 inches³

a coin is biased so that the probability a head comes up when it is flipped is 0.6. what is the expected number of heads that come up when it is flipped 10 times
A coin is biased so that the probability a head comes up when it is flipped is 0.6. Therefore, we can expect to get 6 heads when a biased coin with a probability of 0.6 for heads is flipped 10 times.
To find the expected number of heads when a biased coin is flipped 10 times, we can use the formula:
Expected number of heads = Probability of getting a head × Number of times the coin is flipped
In this case, the probability of getting a head is 0.6 and the coin is flipped 10 times. So the expected number of heads is:
Expected number of heads = probability of getting a head x number of times flipped
Expected number of heads = 0.6 x 10
Expected number of heads = 6
Therefore, the expected number of heads when the coin is flipped 10 times is 6.

Assume that x and y are both differentiable functions of t and find the required values of dy/dt and dx/dt.
xy = 4
find dy/dt, given x = 4 and dx/dt = 13.
The value of dy/dt is -52/x².
What is implicit differentiation?
The process of finding the derivative of a dependent variable in an implicit function by differentiating each term separately, by expressing the derivative of the dependent variable as a symbol, and by solving the resulting expression for the symbol.
From the given expression, the value of dy/dx is calculated as follows;
xy = 4
y = 4/x
y = 4x⁻¹
dy/dx = -4x⁻² = -4/x²
dx/dt = 13
value of dy/dtdy/dt = dy/dx . dx/dt

Find the area of the circle.
Use 3.14 for π. Do not round your answer.
10 inches
Area = [?] inches²
Hint: Area = πr²
Step-by-step explanation:
Using the formula for the area of a circle, we have:
Area = πr²
where r is the radius of the circle.
Given that the radius is 10 inches, we can substitute this value into the formula to get:
Area = π(10)²
Area = 100π
Therefore, the area of the circle is 100π square inches. We can leave the answer in terms of π and do not need to round it.

What is the equation of the line that passes through the point (-6, 5) and has a
slope of - 3/2
Answer:
y = - \(\frac{3}{2}\) x - 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - \(\frac{3}{2}\) , then
y = - \(\frac{3}{2}\) x + c ← is the partial equation
to find c substitute (- 6, 5 ) into the partial equation
5 = 9 + c ⇒ c = 5 - 9 = - 4
y = - \(\frac{3}{2}\) x - 4 ← equation of line
Juwad picked 30 bags of apples on Monday and sold them at his fruit stand for
$3.45 each. The following week he picked and sold 26 bags.
How much money did Juwad earn in the first week?
How much money did he earn in the second week? How much did Juwad earn selling bags of apples these two weeks? Each bag Juwad picked holds 15 apples. How many apples did he pick in two
weeks?
Answer:
89.70 dollars
Step-by-step explanation:
If Juwad picked 30 bags of apples and only sold 26 of them for 3.45 each, then you would have to multiply the number of bags sold by the price, and you would get your answer. So in this case:
1. (#sold)* (price)= total amount of money made
2. 26*3.45= 89.70
3. And you can check by dividing 89.70(your answer) by the price of the apples
4. 89.70/3.45= 26

paul opens a saving account and he deposits 150 per month. assume that he does not withdraw money or make any additional deposits.after 6 months there is 1,250 in his saving account
1) write an equation that represents the total amount of money paul deposits into his aacount (point slope form)
2) after how many months will paul have 2000 in his account?
point slope form formula: y-y=m(x-x)
Answer: it will take Paul 11 months to have $2,000 in his account, assuming he does not withdraw any money or make any additional deposits.
Step-by-step explanation:
Let x be the number of months that Paul has deposited money into his account. The total amount of money he deposits can be represented by the equation y = 150x, where y is the total amount of money in his account after x months.
To find the value of y after 6 months, we can substitute x = 6 into the equation:
y = 150(6) = 900
However, we know that the actual amount of money in Paul's account after 6 months is 1,250. This means that he must have earned interest on his deposits.
To account for the interest, we can add a constant term to the equation, representing the amount of interest earned. Let's call this constant term b. Then the equation becomes:
y = 150x + b
We know that when x = 6, y = 1,250. We can use this information to solve for b:
1,250 = 150(6) + b
b = 1,250 - 900
b = 350
So the equation that represents the total amount of money Paul deposits into his account is:
y = 150x + 350 (in point slope form, this is y - 350 = 150(x - 0)).
To find the number of months it will take for Paul to have $2,000 in his account, we can set y = 2,000 in the equation and solve for x:
2,000 = 150x + 350
1,650 = 150x
x = 11
Therefore, it will take Paul 11 months to have $2,000 in his account, assuming he does not withdraw any money or make any additional deposits.
7th grade math help me pleaseee :)
Answer:
answer of 2a)
He started with $24 and spent $16. Let a represent his account balance after he bought the notebook and pens. Then
24–16=a
His new account balance is $8.
He has $8 in his account and then he deposited b dollars. His account balance is now $28. Then
8+b=28
His deposited $20 in his account.
He has $28 and spent $34. Let c represent his account balance after he bought the book. Then
28–34=c
His new account balance is -$6.
He started with an account balance of -$6 and paid the debt off so his account balance is 0. If d is the amount money he deposited to pay off his debt, then
−6+d=0
He deposited $6.
answer of 2b)
If he spends more than he has in his account, then we are subtracting a bigger number from a smaller number, and the result is negative. ... The opposite of a positive number is a negative number, so it makes sense to represent his account balance with a negative number when he owes money to the bookstore.

Using the given population models, we found that Wyoming's population will surpass Alaska's after 37 years.
What is meant by population models?
A particular category of the mathematical model is called a population model, and it is used to examine population dynamics. Population models are mechanistic models that link alterations in population structure and density to reactions at the individual level. Models help us comprehend the workings of intricate interactions and systems. A feasible way to comprehend how numbers change over time or in connection to one another is by modelling dynamic interactions in nature. By using population modelling as a technique, numerous trends can be seen.
The population model of Alaska is:
\(y = 670,000e^{(0.01293t)}\)
The population model of Wyoming is:
\(y = 515,000e^{(0.020t)}\)
First, we will find when the population becomes the same.
\(670,000e^{(0.01293t)} = 515,000e^{(0.020t)}\)
\(\frac{670,000}{ 515,000} =\frac{e^{(0.020t)}}{e^{(0.01293t)}}\)
\(1.301 ={e^{(0.020t-0.01293t)}}\)
Taking natural logarithms on both sides
ln 1.301 = 0.020t - 0.01293t
0.263 = 0.00707t
t = 37.199 = 37 years
Therefore using the given population models, we found that Wyoming's population will surpass Alaska's after 37 years.

A baseball is hit with an initial vertical velocity of 121 feet per second and the ball was hit 1 foot above ground. How high is the ball after 4 seconds?
h = −16t^2 + 121t + 1
Answer:
After 4 seconds, the ball is at 229 ft
Step-by-step explanation:
Here, we want to get the height of the ball at 4 seconds
What we have to do here is to substitute the value of t for 4 seconds in the equation
We have;
h = -16(4^2) + 121(4) + 1
h = -256 + 484 + 1
h = 229 ft

Answer:
A
Step-by-step explanation:
The linear equation in two variables is given to us is
