Answer:

x = 121

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 7, thus

sum = 180° × 5 = 900°

Sum the given angles and equate to 900

x + 125 + 119 + 117 + 145 + 133 + 140 = 900, that is

x + 779 = 900 ( subtract 779 from both sides )

x = 121

Answer:

Step-by-step explanation:

there are 35 0's in the number

Answer: 320

Step-by-step explanation:

there are 16 tablespoons in one cup so 20*16=320

To calculate the calories in one cup of chocolate chips, you multiply the number of calories per tablespoon (20) by the number of tablespoons in a cup (16), resulting in 320 calories per cup.

To determine how many calories are in 1 cup of chocolate chips, knowing that there are 20 calories in 1 tablespoon, we first need to understand the conversion between tablespoons and cups. There are 16 tablespoons in a cup.

Therefore, to find out how many calories are in a full cup, you would simply multiply the number of calories in one tablespoon by the number of tablespoons in a cup:

20 calories / tablespoon × 16 tablespoons / cup = 320 calories / cup.

Thus, there are 320 calories in 1 cup of chocolate chips.

Answer:

A. "an arithmetic sequence with a common difference (d) of -6."

B. 33 hours

C. [tex]a_n=a_1+(n-1)d[/tex]

D. See below

Step-by-step explanation:

A.

Since the sequence lessens by 6, this is an arithmetic sequence with a common difference (d) of -6.

B.

The formula for term of arithmetic sequence is:

[tex]a_n=a_1+d(n-1)[/tex]

Wher a_1 is the first term and d is the common difference. Since we want to find after 33 weeks, we plug in 33 into n:

[tex]a_{33}=225 + (-6)(33-1)\\a_{33}=33[/tex]

She will have left 33 hours

C.

We will use the arithmetic sequence term formula written above, that is:

[tex]a_n=a_1+(n-1)d[/tex]

THis gives us the amount of hours left after a certain number of weeks.

D.

We plug in 40 into n and find the hours left:

[tex]a_{40}=225+(40-1)(-6)\\a_{40}=225-234\\a_{40}=-9[/tex]

THis term is NEGATIVE, which means that Greta will not have to work 40 weeks to fulfill the target of 225 hours. She needs to work less.

This sequence represents the number of volunteer hours Greta has left after each week has passed. After 33 weeks, Greta has 27 hours left to fulfill her requirement. After 40 weeks, the formula gives a negative value, which means she has completed her requirement and has 15 extra hours of volunteer work completed.

a. This sequence represents the number of volunteer hours Greta has left after each week has passed for her community service project.

b. To determine how many volunteer hours Greta has left after 33 weeks, we can subtract the number of hours she has volunteered in those 33 weeks from the initial requirement of 225 hours. Therefore, Greta has 225 - (6 * 33) = 225 - 198 = 27 hours left.

c. To determine how many volunteer hours Greta has left after 40 weeks, we can use the same formula as in part b. Therefore, Greta has 225 - (6 * 40) = 225 - 240 = -15 hours left.

d. Since we cannot have negative hours, the answer in part c does not make sense in the context of the problem situation. It means that Greta has fulfilled her requirement and has 15 extra hours of volunteer work completed.

Answer:

512 in³

Step-by-step explanation:

Given the volume (V) of a cube is calculated using

V = s³ ← s is the side length

When s = 8, then

V = 8³ = 8 × 8 × 8 = 64 × 8 = 512 in³

Answer: 512 in.³

Step-by-step explanation: To find the volume of a cube, first start with writing down the formula for the volume of a cube which is as followed.

Volume = Length × Width × Height

In this problem, our prism is a cube. Since the length, width, and height of a cube are all equal, we can find the volume of a cube by simply multiply side times side times side or s³.

Volume = Length x Width x Height

Volume = (8) (8) (8)

Volume = 512 in³.

Therefore, the volume of the cube is 512 in.³.

Answer:

a. (1,14) and (7,7)

b. slope = -1.2

Step-by-step explanation:

a. Use the points that are actually on the drawn line

(1,14) and (7,7)

b. Slope formula is :

[tex]slope = ( y_{2} - y_{1}) \div ( x_{2} - x_{1})[/tex]

It doesnt matter which one is 1 or 2. I will take (1,14) as (x1, y1) and (7,7) as (x2, y2)

[tex]slope = \frac{(7 - 14)}{(7 - 1)} \\ = \frac{ - 7}{6} = - 1.1667 = - 1.2[/tex]

Answer:

(A) (1, 14) and (7, 7)

(B) -1.17

Step-by-step explanation:

(A) the 2 points that should be used are: (1, 14) and (7, 7). The reason is that these 2 points are the closest to the trend line.

(B) With 2 points - (x1, y1) and (x2, y2) - a linear equation can be obtained. The slope (m) of the line is computed as follows:

m = (y2 - y1)/(x2 - x1)

m = (7 - 14)/(7 - 1) = -1.17

Answer:

C

Step-by-step explanation:

This is a linear equation in one variable and has 1 solution

12x + 6 = 5x ( subtract 5x from both sides )

7x + 6 = 0 ( subtract 6 from both sides )

7x = - 6 ( divide both sides by 7 )

x = - [tex]\frac{6}{7}[/tex] ← 1 solution

The equation has a single solution for x, which is -6/7. The correct answer is: C. 1

To determine the number of solutions to the equation 12x + 6 = 5x, let’s solve the equation step by step.
First, we need to get all terms with the variable x on one side of the equation and constants on the other side. To do this, we can subtract 5x from both sides of the equation:
12x + 6 - 5x = 5x - 5x
This simplifies to:
7x + 6 = 0
Now we need to isolate the term with the x variable, so we subtract 6 from both sides of the equation:
7x + 6 - 6 = 0 - 6
This further simplifies to:
7x = -6
Finally, to solve for x, we divide both sides by 7:
7x / 7 = -6 / 7
x = -6/7
Therefore, the equation has a single solution for x, which is -6/7.
The correct answer is:
C. 1

Step-by-step explanation:

In this Congruence of Triangles question, To show that ABC = XYZ by SAS congruence, we also need to show that AC = XZ and ∠A = ∠X.

To show that ABC = XYZ

AB = XY (Given)

A = X (Given)

To prove ABC = XYZ by the Side-Angle-Side (SAS) congruence postulate, we need to show that one pair of corresponding sides and the included angle are congruent. In this case:

AC = XZ (By the reflexive property of congruence)

∠A = ∠X (Given)

Therefore, to fully demonstrate the congruence between the two triangles ABC and XYZ, we also need to show that AC = XZ and ∠A = ∠X.

We can tell this side on triangle ABC is BC, and the side on triangle XYZ is YZ, so the answer must be B.

SAS stands for side-angle-side, which indicates that for two triangles to be congruent, all two sides and the angle they produce must be congruent and equal.

You have an angle, <B and <Y, and a side, AB and XY, in this instance. The last side, which produces angle B along with side AB on triangle ABC and angle Y along with side XY on triangle XYZ, is all that is needed to finish this.

In this case, you have a side—AB and XY—and an angle, <B and <Y. To complete this, you simply need the final side, which forms angle B along with side AB on triangle ABC, and forms angle Y along with side XY on triangle XYZ.

By looking at the diagram, you can tell this side on triangle ABC is BC, and the side on triangle XYZ is YZ, so the answer must be B. The answer must be the sides of triangles ABC and XYZ are, respectively, BC and YZ.
