Please answer 1 and 2

Answer:

Option C should be the answer.

Given:

The area model.

To find:

The area as a sum and area as a product.

Solution:

The four terms of the area model are [tex]2x^2,10x, 3x, 15[/tex].

The area as a sum is the sum of all the terms of given area model.

Area as a sum = [tex]2x^2+10x+3x+15[/tex]

                        = [tex]2x^2+13x+15[/tex]

The area as a product is the factor form of sum of all the terms of given area model.

Area as a product = [tex]2x^2+10x+3x+15[/tex]

                        = [tex]2x(x+5)+3(x+5)[/tex]

                        = [tex](x+5)(2x+3)[/tex]

Therefore, the area as a sum is [tex]2x^2+13x+15[/tex] and the area as a product is [tex](x+5)(2x+3)[/tex].

Answer:

y intercept is -8

slope is 3x

Step-by-step explanation:

the definitions of them speak for themselves

Answer: y = 31

Step-by-step explanation: all you need to do is plug in the x

since x = -21 we can put: -21 + y = 10

now we add 21 to both sides giving us: y = 31

Answer:

(-21,22)

Step-by-step explanation:

x+y=10

x=-21

subtitue the x value

-21+y=2

solve for y

y=22

Then write your answer by ordered pair

(-21,22)

Answer:

B 1/3 then reflection across y axis then move figure 2 units to down and 1 right.

Step-by-step explanation:

The figure ABC is bigger than FED so the scale factor is less than one since we are going to ABC to FED. Let look at corresponding sides, AB and FE. AB distance is 3. FE distance is 1 so let divide

[tex] \frac{fe}{ab} [/tex]

[tex] \frac{1}{3} [/tex]

The scale factor is 1/3.

The new points are at A'(-2,0) B'(-2,1) C'(-1,0).

Then we apply reflection.

Since FED is in the 4th quadrant, we are going to reflect across the y axis.

That becomes using formula

(x,y) goes to (-x,y) when reflecting across yaxis.

A''(2,0) B''(2,1) C''(1,0)

Now we will apply the translation. We can simply just move the figure 2 units down and 1 unit to the right.

A 2-column table with 4 rows. Column 1 is labeled Store with entries A, B, C, D. Column 2 is labeled Advertised Bread Prices with entries 3 loaves for 5 dollars and 94 cents, 4 loaves for 7 dollars and 80 cents, 5 loaves for 10 dollars and 5 cents, 6 loaves for 12 dollars and 12 cents.

Camillo is making gourmet peanut butter and jelly sandwiches for a food challenge.

PLS HELP ASAP!!What is the unit price of a loaf of bread at each store?

Store A:

Store B:

Store C:

Store D:

Solution:

The unit price of an item is the price for a single unit of measure of that item. It is measured in price / unit measure.

unit price of a loaf of bread at each store = cost of the loaf of bread / number of loaves

For store A, unit price = $5.94 / 3 loaves = $1.98 per loaf

For store B, unit price = $7.80 / 4 loaves = $1.95 per loaf

For store C, unit price = $10.50 / 5 loaves = $2.10 per loaf

For store D, unit price = $12.12 / 6 loaves = $2.02 per loaf

Answer:

yup the person above me is right but for C its $2.01 :>

Answer:

Its red becasue 1/2 is greater than all of them

The most likely color of the marble that will be chosen is red.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

We are given that;

Number of red marbles in the bag=1/2

Number of blue marbles in the bag=1/4

Number of green marbles in the bag=1/6

Number of yellow marbles in the bag=1/12

Now,

To determine the most likely color of the marble that will be chosen, we need to calculate the probability of selecting each color. The probability of selecting a red marble is 1/2, the probability of selecting a blue marble is 1/4, the probability of selecting a green marble is 1/6, and the probability of selecting a yellow marble is 1/12.

To compare the probabilities, we need to find a common denominator. The common denominator for 2, 4, 6, and 12 is 12. So, we can rewrite the probabilities as:

Probability of selecting a red marble = 6/12

Probability of selecting a blue marble = 3/12

Probability of selecting a green marble = 2/12

Probability of selecting a yellow marble = 1/12

Since the probability of selecting a red marble is the highest among all the colors, it is the most likely color to be chosen.

Therefore, by probability the answer will be red marble.

Answer:

C. AB/EF = BC/EF

Step-by-step explanation:

If the triangles are similar then the ratio of these side lengths must be equal.

Given:

The company charges $250 for the onetime set-up fee and $23 for each printed jersey.

To find:

The expression that represents the total cost of x number for the team.

Solution:

We have,

Fixed charges = $250

Additional charges = $23 per printed jersey

Let x be the number of printed jersey. Then,

Additional charges = $23x

Total chargers = Fixed charges + Additional charges

                        = $(250 + 23x)

Therefore, the expression for the total charges is $(250 + 23x).

Answer is D

Step-by-step explanation:

(3,-7) and (1,-10) belong toD Variant

The required function is [tex]y=-\frac{3}{4}(x-3)^2-7[/tex] , so the correct option is D.

Important information:

The vertex form of a quadratic function is:

[tex]y=a(x-h)^2+k[/tex]

Where, [tex]a[/tex] is constant and [tex](h,k)[/tex] is vertex.

Substitute [tex]h=3,k=-7[/tex].

[tex]y=a(x-3)^2-7[/tex]        ...(i)

Graph passes through the point (1, -10). Substitute [tex]x=1,y=-10[/tex] in (i).

[tex]-10=a(1-3)^2-7[/tex]

[tex]-10+7=4a[/tex]

[tex]-3=4a[/tex]

[tex]\dfrac{-3}{4}=a[/tex]

Substitute [tex]a=-\dfrac{3}{4}[/tex] in (i).

[tex]y=-\frac{3}{4}(x-3)^2-7[/tex]

Therefore, the correct option is D.

Answer:

54 foot long pieces

Step-by-step explanation:

Jack has 18 yards of fabric that he wants to cut into pieces that are each 1 foot long. How many one-foot long pieces can Jack create? Come up with two different strategies for solving. (1 yd = 3 ft)

Step 1

Convert yards to foot

1 yd = 3 ft

18 yards = x

Cross Multiply

x = 18 × 3 ft

= 54 ft

Step 2

He wants to cut into pieces that are each 1 foot long. How many one-foot long pieces can Jack create?

This is calculated as:

1 foot = 1 piece.

54 feet = x

x = 54 × 1 piece

x = 54 pieces
