The graph of a function is shown on the grid.

Step-by-step explanation:

9) volum = width× lenght × height

= 2×3×7 = 42 m³

10) = 7³ = 343 cm³

Answer:

Question 9: Volume = 42m

Question 10: Volume = 343cm

Step-by-step explanation:

Volume for a rectangular prism: V = length x height x width

Question 9:

Length = 7m

Width = 2m

Height = 3m

V = (7m) x (2m) x (3m)

V = 14m x 3m

Volume for a cube: V = a^3 → this is the formula since all sides are the same length

Question 10:

Length = 7cm

Width = 7cm

Height = 7cm

V = (7cm) x (7cm) x (7cm)

V = 49cm x 7cm

V = 343

OR

V = a^3 → (7)^3

Answer:

B. x-(0.5x+20)=300

Step-by-step explanation:

Because you add 20 to half of John's monthly allowance, and 0.5x is saying John's allowance divided by 2. Then you have Melissa's allowance, which then you add to John's allowance to get the total of $300 combined.

The equation that describes the situation would be; A. x-(0.5x+20)=300

An equation is an expression that shows the relationship between two or more numbers and variables.

We are given that Melissa and John get a combined monthly allowance of $300. Melissa's monthly allowance is $20 more than half of John's monthly allowance.

When x represents John's allowance, in dollars

Since we add 20 to half of John's monthly allowance, 0.5x is saying John's allowance is divided by 2.

Now we have Melissa's allowance, which then adds to John's allowance to get a total of $300 combined.

The equation becomes as;

x-(0.5x+20)=300

Answer:

The weight : 9 pound

Lamar would pay for his dinner : $71

Step-by-step explanation:

Let x represent the weight of the lobster

the cost of the dinner at restaurant 1 is 4x + 35  

the cost of the dinner at restaurant 2 is 3x + 44

Now ,we have to solve the equation :  

4x + 35 = 3x + 44

-3x - 35   -3x  - 35    -> trying to get all x terms on one side. other just #

4x - 3x = 44 - 35

⇔ 1x = 9

⇔ x = 9

In this case Lamar would pay the same amount for his dinner at any restaurant:

the price = 4×(9)+35 = 71

               = 3×(9)+44 = 71.

Hope this helps, Let me know if you have any question/concerns !

keeping in mind that a rhombus is also a parallelogram, namely a quadrilateral with parallel opposite sides, however, a rhombus sides are all the same length, and its diagonals meet at right-angles, Check the picture below.

The ratio of the required trigonometric function sin b₂° as per the given measurement of the quadrilateral is equal to 39/ 50.

Let us consider quadrilateral ABCD be rhombus.

Using the properties of the rhombus,

All the sides are congruent to each other.

Here, AB = 5 cm

This implies,

AB = BC = CD = AD = 5 cm

And Intersection of the diagonal is point 'O'.

In rhombus diagonals bisects each other at 90 degrees.

Measure of angle BOC = 90 degrees.

Triangle BOC is right angled triangle.

OC = 3.9 cm

sin b₂° = opposite side / hypotenuse

           = OC / BC

           = 3.9 / 5

           = 0.78

            = 78 / 100

            = 39 / 50

Therefore, the ratio of the function sin b₂°  is equal to 39 / 50.

The distance between the coordinates of house and store is D = 17 miles, or about 4.12 miles

The distance of a line between 2 points is always positive and given by the formula

Let the first point be A ( x₁ , y₁ ) and the second point be B ( x₂ , y₂ )

The distance between A and B is D , and the distance D is

Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²

Given data ,

Let the first point be P = P ( -8 , -9 )

Let the second point be Q = Q ( -4 , -10 )

Now , Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²

D = √ ( -8 + 4 )² + ( -9 + 10 )²

On simplifying , we get

D = √ ( 4 )² + ( 1 )²

D = √17 units

And , 1 unit = 1 mile

So , √17 units = 4.12 miles

Hence , the distance between Jose's house and the store is √17 miles, or about 4.12 miles

The researcher should use regression analysis, as a statistical tool,  because the researcher is working with two variables measured.

Regression analysis is the most widely used statistical tool that can be used to find out the relation between a set of variables. Thus, from its results, it is possible to analyze the trend or make predictions.  In a regression analysis, it is considered the relationships between two or more variables and it is very similar to correlation.

Like the researcher is working with two variables measured at the interval level. The researcher should use regression analysis.

Answer:

50 degrees

Step-by-step explanation:

If AB is congruent to BC, then angles BAC and BCA are congruent.

Angle DCB+ angle BCA= 180 degrees

180 degrees- 115 degrees= 65 degrees

It means that angles BCA and BAC (which are congruent) are equal 65 degrees.

Sum of angles i side a triangle is 180 degrees so:

180 degrees- 2*65 degrees= 180 degrees- 130 degrees= 50 degrees

The angle ABC is equal to 50 degrees.

This is simply because the x coordinate is 6 and the y coordinate is 2.

The line x = 6 is a vertical line in which all points on it have an x coordinate of 6. It goes through 6 on the x axis.

The line y = 2 is horizontal where all points on it have a y coordinate of 2.

The vertical and horizontal lines intersect at (6,2)

well, keeping in mind that a year has 12 months, that means that 8 months is 8/12 of a year, when Mrs Rojas pull her money out.

well, she put in 6000 bucks, got back 160 extra, that's the interest earned in the 8 months.

what if she had left her money for 1 whole year, then

so had she left it in for a year, she'd have gotten 6240, namely 240 in interest, well, what fraction of a year's interest was earned? or worded differently, what fraction is 160(8 months) of 240(1 year)?

Answer:

  (a)  88 m²

Step-by-step explanation:

The area of a composite figure can be found by decomposing it into figures whose areas are easy to calculate. This figure can be decomposed any of several ways (as is often the case).

Drawing a vertical line down from the top-edge vertex, we can divide the figure into a trapezoid on the left and a rectangle on the right.

__

The trapezoid will have (vertical) bases of 4 m and 6 m, and a height of (16-8) = 8 m. Its area is ...

  A = 1/2(b1 +b2)h = 1/2(4 +6)(8) = 40 m²

The rectangle on the right is 8 m wide and 6 m high, so its area is ...

  A = LW = (8 m)(6 m) = 48 m²

The total area is ...

  trapezoid area + rectangle area = 40 m² +48 m² = 88 m²

The area of the composite figure is 88 m².
