7TH GRADE MATH!!!!!!

Answer:

19

Step-by-step explanation:

Since it is a 90° angle we can say that 3x-15+2x+10 = 90.

3x-15+2x+10 = 90

5x-5=90

5x=95

x=19

By solving this we find that x is equal to 19.

Answer:

19

Step-by-step explanation:

3*19 = 57

57 - 15 = 42

2*19 = 38

38 + 10 = 48

48 + 42 = 90

(As this is a 90 degree angle)

Answer:

Which cube?

Step-by-step explanation:

................

Answer:

first one y: -3, 0, 3, 6, 12

second one y:5, 2, 0, 2, 5

Step-by-step explanation:

for the first one the equation is y=3x

so when it goes as x:-1, 0, 1, 2, 4

so you should multiply each number by 3 as the equation does

(just replace each number by x in the equation)

so y: -3, 0, 3, 6, 12

next one: equation is y=[tex]x^{2}[/tex]+1

so do the same as up there: replace x with every number

x:-2, -1, 0, 1, 2

so y will be

y:5, 2, 0, 2, 5

Answer: B

O RST ~ RQP

Step-by-step explanation:

The statement that is true based on the diagram is: "QR corresponds to TR."

Based on the given information, we have the following:

1. PQ = 8 cm

2. QR = 12 cm

3. RT = 18 cm

4. ST = x cm (length not specified)

Now, let's analyze the statements:

1. [tex]\( \triangle PQR \sim \triangle STR\)[/tex] - This statement is not necessarily true because we don't have enough information to determine if the two triangles are similar.

2. [tex]\( \triangle RST \sim \triangle RQP\)[/tex] - This statement is not necessarily true because we don't have enough information to determine if the two triangles are similar.

3. QR corresponds to TR - This statement is true based on the fact that QR and TR are corresponding sides of the triangles [tex]\(\triangle PQR\)[/tex] and [tex]\(\triangle STR\)[/tex] that are intersected by transversal QRST.

4. PR corresponds to RS - This statement is not necessarily true because we don't have enough information to determine if PR and RS are corresponding sides of the triangles [tex]\(\triangle PQR\)[/tex] and [tex]\(\triangle STR\)[/tex].

So, the correct answer is: QR corresponds to TR.

Answer:

D : 510 units

Step-by-step explanation:

NOTE:

Something to consider when solving problems like this is to break the large shape down into smaller, more managable shapes. So for this problem, you can break down this irregular shape into two rectangles. This will make solving problems similar to this easier in the future :)

WORK:

I broke down this shape into two rectangles with the following dimensions:

- 12 meters by 5 meters

- 3 meters by 14 meters

You also know that the depth has to be 5 feet (the problem itself did not account for differences in feet and meters, as when I converted the 5 feet to meters and solved that way, none of the answers were correct)

Using this information, you can now solve for the volume of each of the rectangles

12*5*5 = 300 units

3*14*5 = 210 units

Then, you simply add the two volumes together to find the total volume needed to fill the pool which equals

510 units

Function Modeling

The behavior of some parameters that depend on a set of variables can be modeled in several ways, like linear, quadratic, exponential, logarithmic, among many others.

The selection of the model is often a complex decision that involves statistics and data analysis.

The question provides us with four points where the volume of popcorn bags and the price in dollars. The easiest function that can be used is the line.

The equation of a line of the volume V and the price p can be found with the expression

We'll use the first two values (6,10) (8,20)

Simplifying and rearranging, we get the model

To test the accuracy of the model, we compute the values of p for V=35 and for V=48

Since the computed values are equal to those of the table, the model is accurate. We can now predict the price for V=60

The price for a 60-ounce bag of popcorn would be $16

Answer:

1) -3/2

Step-by-step explanation:

The common ratio is the amount you multiply by to get to the next number in the sequence. To calculate this you will need to divide the term by its preceding term.

For example (3/4) / (-1/2)

When dividing by fractions you should apply KCF (Keep Change Flip), so you will end up with (3/4) x (-2/1) = -3/2

Check this by doing the next term (-9/8) / (3/4)

When dividing by fractions you should apply KCF (Keep Change Flip), so you will end up with (-9/8) x (4/3) = -3/2

Answer:

consistent  

A consistent and independent solution to a system of linear equations is one point

A consistent and dependent solution to a system of linear equations is where they are the same line ( they could also be called equivalent)

An inconsistent solution is where there is no solution, the lines do not cross

Since the lines cross at exactly one point, this is a consistent and dependent solution

The solution is at x = 3  ( 3 units to the right of the origin)

and y = 2 ( 2 units up from the origin)

Answer:

27

Explanation:

5 * 3 = 15 (5 triangles with 3 angles each)

3 * 4 = 12 (3 rectangles with 4 angles each)

15 + 12 = 27

Answer:

the answer is 27 because a triangle has 3 sides so multiply 3 tomes 5 because of how many triandles and then the same with the rectangle that has 4 sides then multiply by 3 because of the number of triangles you have

Answer:

3.33%

Step-by-step explanation:

Rate = 100xSI / PxT

P = 1000

SI = 100

T = 3

Answer:

  40°, 60°, 80°

Step-by-step explanation:

The total of ratio units is 2+3+4 = 9.

The total of angles in a triangle is 180°, so each ratio unit stands for 180°/9 = 20°.

The angle measures are ...

  20° × 2 = 40°

  20° × 3 = 60°

  20° × 4 = 80°
