Answer 1

Hey there!

Let's look at all our constraints and find figure out what our answer is.

Since everything here is division, everything is a quotient of 2 quantities, so that doesn't help us. For the next one, our numerator should be the product (signifies multiplication) of 5 and the sum of x and y. That looks like:

5(x + y)

If we look at the last constraint, we see that denominator is a product, or multiplying -8 and x, which looks like -8x.

Therefore, our answer must be A. It fulfills all the constraints, unlike the others.

Which expression is equivalent to 2 3 (3x + 9y) + 1 2 (4x - 2y)? A) x + 4y B) 8x - y C) 4x + 5y D) 2x + 5y

Answers

The correct answer is C) 4x + 5y.

We use the Distributive Property on both parts of this:

2/3(3x + 9y) + 1/2(4x - 2y)
= 2/3(3x) + 2/3(9y) + 1/2(4x) - 1/2(2y)
= 6/3x + 18/3y + 4/2x - 2/2y
= 2x + 6y + 2x - 1y

Combine like terms and we have:
4x + 5y

the correct answer is c

Rachel has 60 scones. She sells them to Robbie, Cameron, Louis, Tom and Charlie in that order. Each customer buys more scones then the last and the increase is the same number in each case. Robbie and Cameron's combined total number of scones is three sevenths of the total of Louis, Tom and Charlie. How many scones does each boy buy?

Answers

Robbie bought the smallest amount. Let's use x for that amount.
Let's use n for amount that each following customer increases.

We have:
Robbie=x
Cameron=x+n
Louis=x+n+n
Tom=x+n+n+n
Charlie=x+n+n+n+n

We know that they bought total of 60 scones.
Robbie + Cameron + Louis + Tom + Charlie = 60
x + x+n + x+n+n + x+n+n+n + x+n+n+n+n = 60
5x + 10n = 60 /:5
x + 2n = 12

We are also given this information:
(Robbie + Cameron) = 3/7 * (Louis + Tom + Charlie)
We insert the equations from above:
(x + x+n) = 3/7 * (x+n+n + x+n+n+n + x+n+n+n+n)
2x + n = 3/7 * (3x + 9n) /*7
14x + 7n = 3* (3x + 9n)
14x +7n = 9x + 27n
We take everything on the left side.
14x + 7n - 9x - 27n = 0
5x - 20n = 0/:5
x - 4n = 0

Now we have two equations:
x + 2n = 12
x - 4n = 0
We solve second one for x and insert it into first one.
x + 2n = 12
x = 4n

4n + 2n =12
6n = 12 /:6
n = 2
x=4*2
x=8

Now we can solve for the amount for each customer.
Robbie=x = 8
Cameron=x+n = 8 + 2 = 10
Louis=x+n+n = 8 + 2 + 2 = 12
Tom=x+n+n+n = 8 + 2 + 2 + 2 = 14
Charlie=x+n+n+n+n = 8 + 2 + 2 + 2 + 2 = 16

Yadira made a wooden cone with a radius of 1.9 inches and a height of 15 inches. What is a good estimate of the volume of this cone?

Answers

1/3 x 3.14 x 1.9^2 x 15

=56.677inches3

The good estimate of the volume of the cone is 56.70 cubic inches whose radius is 1.9 inches and height of the wooden cone is 15 inches.

What is a cone?

It is defined as the three-dimensional shape in which the base is a circular shape and if we go from circular base to top the diameter of the circle reduces and at the vertex, it becomes almost zero.

Yadira made a wooden cone with a radius of 1.9 inches and a height of 15 inches therefore,

The radius of the wooden cone r = 1.9 inches

The height of the wooden cone h = 15 inches

We know the volume of a cone is given by:

[tex]\rm V = \pi r^2 \frac{h}{3}[/tex]

Put the values of the r and h, we get:

[tex]\rm V = \pi( 1.9^2) \frac{15}{3}[/tex]

V = 3.61×5×π

V = 56.70 cubic inches

Thus, the good estimate of the volume of the cone is 56.70 cubic inches whose radius is 1.9 inches and height of the wooden cone is 15 inches.

What is the y-intercept of the continuous function in the table?

Answers

Final answer:

The y-intercept of a function is where the graph crosses the y-axis, represented by 'b' in the equation y = mx + b. If a table doesn't show x as zero, one can use the line of best fit by inserting the median x and y values and the slope into the formula b = y - mx to calculate the y-intercept.

Explanation:

The y-intercept of a continuous function can be understood as the point where the function's graph crosses the y-axis. It is typically represented by the variable b in the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept. In the context of the problem provided, if the student is examining a table of values representing a linear relationship, they should look for the value of y when x equals zero to determine the y-intercept directly.

However, if the data does not include an x-value of zero, they could use the line of best fit to calculate the y-intercept by plugging the median x and y values, along with the determined slope, into the formula b = y - mx, where y and x are the medians. For example, if given a slope (m) of 0.09, sum of median x values as 1264, and sum of median y values as 219.5, the y-intercept (b) would be calculated as b = 219.5 - 0.09(1264), which simplifies to approximately 35.25.

This calculation would be necessary if the student is working with data that does not directly provide a scenario where x = 0, such as exam scores or years in a dataset stating from year 1. It's important to note that in some real-world applications, a y-intercept may not be meaningful if the x-value cannot be zero, like in the case of time-based data where the year 0 does not exist.

The y-intercept of the continuous function is (-2). This means that the graph of the function intersects the y-axis at the point (0,-2).

The y-intercept of a continuous function represents the point where the graph of the function intersects the y-axis. In other words, it is the value of y when x is equal to zero.

Looking at the given points:

(0,-6), (-2, 0), (-6, 0), (0,-2), and 0

We can determine the y-intercepts by identifying the points where x is equal to zero.

Let's go through the points one by one:

1. (0,-6): This point does not have a y-intercept because the x-coordinate is not zero.

2. (-2, 0): This point also does not have a y-intercept because the x-coordinate is not zero.

3. (-6, 0): Again, this point does not have a y-intercept because the x-coordinate is not zero.

4. (0,-2): Finally, this point does have a y-intercept because the x-coordinate is zero. Therefore, the y-intercept is -2.

5. 0: This is not a point, but simply the value of zero. It does not have a y-intercept because it does not represent a point on the graph.

To summarize, the y-intercept of the continuous function is (-2). This means that the graph of the function intersects the y-axis at the point (0,-2).

dining room furniture with a cash price of $1,900 at $100.00 down and $90.00 per month for 24 months a. $ b. $ c.

Answers

The total cost is $2,260.

The question involves calculating the total cost of purchasing dining room furniture with an initial down payment and subsequent monthly payments. First, we account for the down payment: $1,900 (cash price) - $100 (down payment) = $1,800 remaining balance. This balance will be paid over 24 months at $90 per month, thus 24 * $90 = $2,160. The total cost of the furniture, including the down payment, would then be the sum of the down payment and the total of the monthly payments: $100 + $2,160 = $2,260.

The total cost of the dining room furniture with this payment plan is $2,260.00.

The total cost for the dining room furniture with the given payment plan.

1. Down Payment: $100.00

2. Monthly Installments: $90.00 for 24 months

Calculate the total cost of the furniture before any payments are made:

[tex]\[ \text{Cash Price} = \$1,900 \][/tex]

The total amount paid through monthly installments:

[tex]\[ \text{Monthly Installment} = \$90.00 \times 24 \text{ months} = \$2,160.00 \][/tex]

Finally, let's add the down payment to the total amount paid through installments to find the overall cost:

[tex]\[ \text{Total Cost} = \$100.00 + \$2,160.00 = \$2,260.00 \][/tex]

Ben has Type 180 word in can type 30 words per minute. Millie has Type 60 words and can type 50 word per minute. How many minutes will it take Millie to catch up with Ben?

Answers

6 minutes.
If x= minutes,
180+30x=60+50x
120=20x
6=x

How many words they have already typed is their starting/ y intercept. Their words per minute is their rate. We need their equations to equal themselves so we can find when they are the same. X will be the amount of minutes and we need X by itself.
180+30x=60+50x
Now let’s subtract 60 from each side.
120+30x=50x
Let’s subtract 30x from each side.
120=20x
