Consider the equation V=6h where V is the volume (in cubic centimeters) of a box with a variable height h in centimeters and a fixed base of area 6cm2.

Answer:

Perimeter o the rectangle = 16x - 2

Step-by-step explanation:

Perimeter of a rectangle = 2(long+ wide)

Then:

Perimeter = 2((6x-4)+(2x+3))

Perimeter = 2(6x+ 2x + 3 - 4)

Perimeter = 2(8x - 1)

Perimeter = 2*8x + 2*-1

Perimeter = 16x - 2

Answer:

1&2)

GH = 28

FH = 56

XY = 7

XZ = 14

3-6) Acute, Obtuse, Acute, Right

7) Perimeter: 40 in. Area: 84 in^2

8) Perimeter: 42 m.  Area: 84 m^2

9) Perimeter: 15.2 yd. Area: 14.44 yd^2

10) 1, 8, 27, 64, 125 These are the cubes of 1, 2, 3, 4, 5 so it's just the cube of the next number that was cubed before.

11) 128, 32, 8, 2, 1/2 Divide the previous number by 4.

12) 2, -6, 18, -54, 162 Multiply the previous number by -3

13-15) I'm sorry we didn't do those so I don't really know how that works sorry.

16) 3x - 14 = 34

3x = 48 Add 14 to each side (to isolate 3x)

x = 16 Divide by 3 both sides (to get x)

17) -4(x+3) = -28

x+3 = 7 divide by -4 on both sides (to get a step closer to solving for x and isolating x+3)

x = 4 subtract 3 from both sides (to get x (isolating x))

18) 43 - 9(x-7) = -x - 6

43 - 9x + 63 = -x - 6 distribute 9 to x and 7 (to expand)

106 - 9x = -x - 6 combine like terms (easier to deal with)

106 - 8x = -6 add x to both sides (so there's only x on one side)

112 - 8x = 0 add 6 to both sides (only one number left)

112 = 8x move -8x to the right side

x = 14 divide by 8 (to isolate x)

19) x = 29 degrees

20) x = 13 degrees

21) x = 9 degrees, y = 31 degrees

Step-by-step explanation:

4x = 5x-7

x = 7

GH = 5(7) - 7 = 35 - 7 = 28

FH = 4x + 5x - 7 = 4(7) + 28 = 28*2 = 56

3x - 5 = x + 3

x = 4

XY = 3(4) - 5 = 12 - 5 = 7

XZ = 7*2 = 14

Acute is < 90

Obtuse is > 90

Right is = 90

Straight is = 180

7) 2(6+14) = 2(20) = 40 in

6*14 = 84 in^2

8) 13+14+15 = 42 m

(12*14)/2 = 6*14 = 84 m^2

9) 3.8*4 = 15.2 yd

3.8^2 = 14.44 yd^2

19) 34 + 4x + 30 = 180

64 + 4x = 180

4x = 116

x = 29

20) 4x + 7x + 37 = 180

11x = 143

x = 13

21) 3y + 42 = 9x + 54

y + 14 = 3x + 18

y = 3x + 4

3y + 42 + 5x + 9x + 54 + 5x = 360

3y + 19x = 264

substitute y with 3x + 4

3(3x + 4) + 19x = 264

9x + 12 + 19x = 264

28x = 252

x = 9

so y = 3(9) + 4 = 27 + 4 = 31

The quartiles of the data are: 60.5,64,66

Option(b) is correct.

The quartile divides the distribution into four groups and calculates the range of values above and below the mean.

A quartile separates the dataset into four categories by dividing the data into three points: the lowest, median, and upper quartiles.

Similar to how the median divides the data in half, with 50% of the measurements falling below it and 50% falling above it, the quartile divides the data into fourths, with 25% of the measurements falling below the lower quartile, 50% falling below the median, and 75% falling below the upper quartile.

The interquartile range, a measurement of variation around the median, is calculated using quartiles.

For the given data set: 58,60,60,61,62,64,64,64,66,70,72

Median = 64

Lower quartile = Median of the lower half = 60.5

Upper quartile = Median of the upper half = 66

The value of diameter and radius of circle is 7 cm and 3.5cm.

According to the statement

we have given that the a figure of circle and we have to find the radius and the diameter of the circle.

So, We know that the

The radius of a circle runs from its center to its edge, the diameter runs from edge to edge and cuts through the center.

Here from the figure it is clear that the

Diameter of circle = 7cm

and the radius of circle we have to find

So,

Radius of circle = Diameter /2

Substitute the values in it then

Radius of circle = 7cm /2

Radius of circle = 3.5 cm.

1) Maximum number of sundaes possible exists 9.

2) Maximum number of milkshakes possible exists 6.

3) Combination that uses the most of both Ice-cream and Strawberries = 7 scoops of ice cream and 1 scoop of strawberries.

A system of inequalities exists the system where the set of more than one inequalities in more than or equivalent to one variable.

Given: A sundae needs 3 ice-cream scoops and 4 strawberries, and a milkshake requires 2 ice-cream scoops and 6 strawberries.

Ramses have to create sundaes and milkshakes with at most 25 ice-cream scoops and 37 strawberries.

Let x represent the number of sundaes he creates and y the number of milkshakes he creates.

We represent in tabular form,

                    Sundae(x)      Milkshake(y)     Total

Ice-cream          3                         2             3x+2y

Strawberries      4                        6             4x+6y

System of inequalities:

Sundaes and milkshakes with at most 25 ice-cream scoops exist

33x+2y ≤ 25.

Sundaes and milkshakes with at most 37 strawberries exist 4x+6y ≤ 37.

1) Maximum number of sundaes possible:

Maximum number of sundaes possible when y = 0

From the graph y = 0 at x = 9.25

Therefore, the maximum number of sundaes possible exists at 9.

2) Maximum number of milkshakes possible:

Maximum number of milkshakes possible when x = 0

From the graph x = 0 at y = 6.167

Therefore, the maximum number of milkshakes possible exists at 6.

3) Combination that utilizes the most of both Ice-cream and Strawberries:

A combination of both is possible there exists an intersection of both the equation.

From the graph, the intersection point exists x = 7.6 and y = 1.1.

Therefore, the Combination that utilizes the most of both Ice-cream and Strawberries = 7 scoops of ice cream and 1 scoop of strawberries.

Answer:

x  = 9, y = 13 , z = - 19

Step-by-step explanation:

3y + 4z = - 37 → (1)

2x + 4y - 3z = 127 → (2)

4y = 52 → (3)

divide both sides by 4 in (3)

y = 13

substitute y = 13 into (2) and solve for z

3(13) + 4z = - 37

39 + 4z = - 37 ( subtract 39 from both sides )

4z = - - 76 ( divide both sides by 4 )

z = - 19

substitute y = 13 and z = - 19 into (2) and solve for x

2x + 4(13) - 3(- 19) = 127

2x + 52 + 57 = 127

2x + 109 = 127 ( subtract 109 from both sides )

2x = 18 ( divide both sides by 2 )

x = 9

solution is x = 9, y = 13 , z = - 19

Based on the given coordinate grid, and the increment for each grid line, the coordinates of point A is ( fraction negative 1 and 1 over 4, fraction 3 over 4) or (-1¹/₄, ³/₄).

The x-value of point A is said to be 5 grid lines to the left of y-axis. This means that the x value will be negative.

The increments are 1/4 so the x-value is:
= -1/4 x 5

= -1¹/₄

The y-value is given by the 3 grid lines above the x-axis which means that this value is positive:

We are required to find the length of a single shift.

First we have to find the proper fraction of the given mixed fractions.

Fraction is combination of numerator and denominator.The number that is present above the division sign is known as numerator and the number that is present below the division sign is known as denominator.

2+3/4=(8+3)/4=11/4

The n:1 ratio is= 8/9 : 1

Just the simple ratio is= 4 : 4.5

Answer: If they worked together, it would take 31.5 minutes

Step-by-step explanation:

There's a certain formula for equations like this:

[tex]\frac{1}{t1} +\frac{1}{t2}=\frac{1}{tb}[/tex]

t1= the time it took for the first person to complete the task.

t2= the time it took for the second person to complete the task.

tb= the time it took for both of them to complete the task.

We have the values for both t1 and t2, but not for tb.

t1= 45

t2= 105

tb= x

[tex]\frac{1}{45} +\frac{1}{105} = \frac{1}{x}[/tex]

Now it's simple algebra, and all we need to do is solve for x

The LCM for both fractions is 315, so now we multiply BOTH sides of the equation by 315.

[tex]\frac{315}{45} + \frac{315}{105} = \frac{315}{x}[/tex]
