wing system of equations. If there is a solution, write your ans 4x+8y=40 6x+3y=6

Answers

Answer 1

The solution of the given system of equations is x = -1 and y = 4.

The given system of equations is 4x + 8y = 40 and 6x + 3y = 6.


To solve this system of equations, we need to use elimination method. We can subtract 6x from both sides of the second equation and subtract 4x from both sides of the first equation. We get:

8y = 40 - 4x and 3y = 6 - 6x


We can now divide both sides of the second equation by 3 to obtain y = 2 - 2x.


We can substitute the value of y from the second equation into the first equation to get 4x + 8(2 - 2x) = 40, which simplifies to -8x = 8. We can solve this equation for x by dividing both sides by -8, resulting in x = -1.


Substituting the value of x into either equation, we can obtain y = 4. So, the solution of the given system of equations is x = -1 and y = 4.

The variable a is jointly proportional to b and c. If a=79 when b=6and c=3, what is the value of a when b=3 and c=7? Round your answer to two decimal places if necessary.

Answers

The value of a is 92.17 when b=3 and c=7.

What is  jointly proportional ?

Jointly proportional refers to a relationship between two or more variables in which all of the variables increase or decrease together in the same ratio. For example, if one variable doubles, the other variables double as well.

The variable a is jointly proportional to b and c, which means that a = k*b*c, where k is the constant of proportionality.

We can use the given values of a, b, and c to find the value of k:
79 = k*6*3
79 = 18k
k = 79/18

Now that we know the value of k, we can use it to find the value of a when b=3 and c=7:
a = k*b*c
a = (79/18)*3*7
a = 92.17

Therefore, the value of a when b=3 and c=7 is 92.17.

Answers

(A). The largest target is Target B since it has the widest radius. (B). The size of Object A is around 44 inches around. (C). Target C has a surface area of around 254 square inches.

What does the term "circumference" mean?

The length of a circle and perhaps other circular geometric object is referred to as its circumference. Anything in a double circular shape that is linear in one dimension is the perimeter.

A). We must contrast the radii of the three objects in order to compare their sizes.

Target A consists of a radius of 7 inches and a width of 14 inches.

The radius of Target B is 10 inches.

Target C has a circumference of 18π inches, so we can use the formula C = 2πr to find its radius:

18π = 2πr

r = 9 inches

Target B is the main market since it has the greatest radius.

B). The circumference of a circle is given by the formula C = 2πr, where r is the radius. For Target A, r = 7 inches, so:

C = 2πr

C = 2π(7)

C ≈ 44 inches (using 3.14 to approximate)

Target A's circumference is therefore around 44 inches.

C). The area of a circle is given by the formula A = πr², where r is the radius. For Target C, we know its circumference is 18π inches, so we can use the formula for circumference to find its radius:

C = 2πr

18π = 2πr

r = 9 inches

Target C's area is as follows because of its 9-inch radius:

A = πr²

A = π(9)²

A ≈ 254 square inches (using 3.14 to approximate)

Target C therefore has a surface area of around 254 square inches.

Determine the length and width of a rectangle if the perimeter is
26 and the length is four​ more than twice the width

Answers

The length and width of the rectangle are 10 and 3, respectively.

Let's use "l" to represent the length of the rectangle and "w" to represent the width. From the problem statement, we've got portions of information:

The perimeter is 26. The formulation for the perimeter of a rectangle is P = 2l + 2w. So we are able to write:

2l + 2w = 26

The length is four extra than twice the width. In equation shape:

l = 2w + four

Now we can use substitution to resolve for the length and width. we will alternative the expression 2w + 4 for l within the first equation:

2(2w + 4) + 2w = 26

Simplifying:

4w + 8 + 2w = 26

6w + 8 = 26

6w = 18

w = 3

So the width of the rectangle is three. To discover the length, we're going to substitute w = 3 into the equation for l:

l = 2w + 4 = 2(3) + 4 = 10

So the length of the rectangle is 10.

Thus, the length and width of the rectangle are 10 and 3, respectively.

928-32y + 84y= 1708

When we simplify, we get the following:

52y = 780

When we

A box contains 5 balls numbered 1, 2, . . . , 5. In each trial
we remove one ball without replacement. Let X be the total number
of trials until all odd numbered balls are removed. Find V ar(3X +
2022

Answers

The variance of 3X + 2022 is -26.

The variable X in this scenario contains the total number of trials until all odd numbered balls are removed from the box without replacement. In order to find the variance of 3X + 2022, we can use the formula for the variance of a linear transformation: V ar(aX + b) = a^2V ar(X).

In this case, a = 3 and b = 2022, so the formula becomes: V ar(3X + 2022) = 3^2V ar(X) = 9V ar(X).

To find the variance of X, we can use the formula for the variance of a discrete random variable: V ar(X) = E(X^2) - [E(X)]^2.

Since X is the total number of trials until all odd numbered balls are removed, we can find E(X) by calculating the expected value of the number of trials until each odd numbered ball is removed. This can be done using the formula for the expected value of a geometric random variable: E(X) = 1/p, where p is the probability of success.

For the first odd numbered ball, the probability of success is 3/5, so E(X) = 1/(3/5) = 5/3. For the second odd numbered ball, the probability of success is 2/4, so E(X) = 1/(2/4) = 4/2 = 2. For the third odd numbered ball, the probability of success is 1/3, so E(X) = 1/(1/3) = 3/1 = 3.

Therefore, the expected value of X is E(X) = 5/3 + 2 + 3 = 14/3.

To find E(X^2), we can use the formula for the expected value of the square of a geometric random variable: E(X^2) = (2 - p)/p^2.

For the first odd numbered ball, E(X^2) = (2 - 3/5)/(3/5)^2 = (10/5 - 3/5)/(9/25) = 7/5 * 25/9 = 35/9. For the second odd numbered ball, E(X^2) = (2 - 2/4)/(2/4)^2 = (8/4 - 2/4)/(4/16) = 6/4 * 16/4 = 24/4 = 6. For the third odd numbered ball, E(X^2) = (2 - 1/3)/(1/3)^2 = (6/3 - 1/3)/(1/9) = 5/3 * 9/1 = 15.

Therefore, the expected value of X^2 is E(X^2) = 35/9 + 6 + 15 = 170/9.

Now we can find the variance of X: V ar(X) = E(X^2) - [E(X)]^2 = 170/9 - (14/3)^2 = 170/9 - 196/9 = -26/9.

Finally, we can find the variance of 3X + 2022: V ar(3X + 2022) = 9V ar(X) = 9(-26/9) = -26.

Therefore, the variance of 3X + 2022 is -26.

Ranjit made pies for a fundraiser. He cut all the pies into eighths. After the first day of the fundraiser Ranjit sold 10 slices and had 2- of the pies left. Write and solve an equation to determine how many pies Ranjit made for the fundraiser.​

Answers

If Ranjit made pies for a fundraiser. The number of pies Ranjit made for the fundraiser is: 26.

How to find the number of pies Ranjit?

Let p = total number of pies that Ranjit made

Let s = Total number of slices of pie that he made.

Since each pie is cut into 8 slices, we have:

s = 8p

After the first day of the fundraiser, Ranjit sold 10 slices, which means he had s - 10 slices left. Since he had 2 whole pies left, we know that he had 16 slices left. Therefore:

s - 10 = 16

Substituting s = 8p, we get:

8p - 10 = 16

Adding 10 to both sides, we get:

8p = 26

Dividing both sides by 8, we get:

p = 3.25

This means that Ranjit made 3.25 pies for the fundraiser.

The total number of slices would have been:

s = 8p = 8(3.25) = 26

On the first day, he sold 10 slices, which means he had 16 slices left. This matches our initial calculation and confirms that our solution is correct.

For a function f(x) and a particular input value x=a, then we may write the difference quotient as
(f(a+h)−f(a))/h
where h≠0.
Now, let Q(x)=3x^2+5x+10 and consider the input value a=3. We could now write the difference quotient as
(Q(3+h)−Q(3))/h
where h≠0h≠0.
Use this difference quotient to calculate the average rate of change of f(x) from x=3 to x=3+h for the following particular values of h.
When h=0.2, the average rate of change of Q(x) is?

Answers

The average rate of change of Q(x) from x=3 to x=3+h for h=0.2 is 21.2.


To find the average rate of change of Q(x) from x=3 to x=3+h, we need to plug in the values of h and a into the difference quotient and simplify.

When h=0.2, the difference quotient becomes:

(Q(3+0.2)−Q(3))/0.2

= (Q(3.2)−Q(3))/0.2

= ((3(3.2)^2+5(3.2)+10)−(3(3)^2+5(3)+10))/0.2

= ((30.24+16+10)−(27+15+10))/0.2

= (56.24-52)/0.2

= 4.24/0.2

= 21.2

Therefore, when h=0.2, the average rate of change of Q(x) is 21.2.

Are all equilateral triangles similar? Use transformation to explain.

Answers

Yes equilateral triangles are similar. Equilateral triangles have the same length for all 3 sides and angles. A small equilateral triangle can have the sides be 2in and a larger equilateral triangle can have sides that are 5in. The triangles would be the same, just different sizes. Think of plates. Let’s say the plates are the same, same color, shape, and make. The only different is the diameter. One plate is larger than the other. Equilateral triangles are just like that.

Jeremy has GHC 502. 0. He gave Owiredu 3/10 of his money. How much did he give Owiredu?

Answers

The amount ( 3 /10 ) of total money given by Jeremy to Owiredu is equal to GHC 150.6.

Total amount of money with Jeremy in GHC is equal to 502.0

Amount of fraction of the money Jeremy gave to Owiredu is equal to

3 / 10.

Amount of money Jeremy gave to Owiredu is equal to

= ( 3 / 10 ) of GHC 502.0

= ( 3 / 10 ) × GHC 502.0

Multiply 3 to the 502.0 in the given expression we get,

= GHC ( 1506 / 10 )

Divide 1506 by 10 in the given expression we get,

= GHC 150 .6

Therefore, amount of money Jeremy gave to Owiredu is equal to GHC 150.6.
