Answer:

-4/5 = x

Step-by-step explanation:

Answer:

3/2

Step-by-step explanation:

x = 3x + 4 - 1

we can subtract 1 from 4

x = 3x + 3

subtract 3x from both sides

-2x = 3

divide both sides by -2

x = -3/2

so -x would equal -(-3/2) = 3/2

Answer:

[tex]V = 97.911in^3[/tex]

Step-by-step explanation:

Given

Shapes: Cube and Cone

Required

Determine the volume

First we calculate the volume of the cube

[tex]V_1 = l^3[/tex]

Where

l = side length = 5.1

[tex]V_1 = 5.1^3[/tex]

[tex]V_1 = 132.651[/tex]

Next, calculate the volume of the cone using:

[tex]V_2 = \frac{\pi r^2h}{3}[/tex]

Where

h = 5.1

[tex]r = \frac{1}{2} * Diameter[/tex]

[tex]r = \frac{1}{2} * 5.1[/tex]

[tex]r = 2.55[/tex]

So, we have:

[tex]V_2 = \frac{\pi r^2h}{3}[/tex]

[tex]V_2 = \frac{\pi * 2.55^2 * 5.1}{3}[/tex]

[tex]V_2 = \frac{22 * 2.55^2 * 5.1}{7*3}[/tex]

[tex]V_2 = \frac{729.5805}{21}[/tex]

[tex]V_2 = 34.74[/tex]

The volume of the figure is:

[tex]V=V_1 - V_2[/tex]

[tex]V_1 = 132.651[/tex]

[tex]V = 132.651 - 34.74[/tex]

[tex]V = 97.911in^3[/tex]

4x=8

Step-by-step explanation:

4x=32

32/4=8

Answer:

x=8

Step-by-step explanation:

4x+25=57

Subtract 25 from both sides:

4x+25-25=57-25

Simplify:

4x=32

Divide both sides by 4:

4x/4=32/4

Simplify:

x=8

Answer:

At least 7 shirts would need to be sold to cover their costs

Step-by-step explanation:

Cost of producing x t-shirts.

The cost of producing x t-shirts is a flat fee of 35 plus 4.25 per t-shirt. So

[tex]C(x) = 35 + 4.25x[/tex]

Earnings of selling x t-shirts:

Charges $10 per t-shirt, so it earns 10 for each t-shirt it sells.

[tex]E(x) = 10x[/tex]

How many shirts would need to be sold to cover their costs?

To cover the costs, we need that the earnings are equal or higher than the costs. So

[tex]E(x) \geq C(x)[/tex]

[tex]10x \geq 35 + 4.25x[/tex]

[tex]5.75x \geq 35[/tex]

[tex]x \geq \frac{35}{5.75}[/tex]

[tex]x \geq 6.09[/tex]

Since we cannot sell a decimal part of a shirt, at least 7 shirts would need to be sold to cover their costs

Answer: b

Step-by-step explanation:

By the alternate interior angles theorem, the angle of elevation and the angle of depression have the same measure.

The measure of angle A is 32 degrees or the measure of the angle of elevation is 32 degrees option (b) 32 degrees is correct.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

It is given that:

The right-angle triangle is shown in the picture.

The right-angle triangle is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

As the two lines are parallel to each other and a transversal is intersect the parallel lines so the angle would be same as 32 degrees

The angle A = 32 degrees

Thus, the measure of the angle A is 32 degrees or the measure of the angle of elevation is 32 degrees option (b) 32 degrees is correct.

Answer:

Adult tickets cost $80, children ticket cost $40

Step-by-step explanation:

Given data

let the number of adults be x

and the number of children be y

so

x+y= 40-------------1

The adult tickets

cost 14 dollars and the children’s tickets cost 12 dollars.

14x+ 12y=  720-------2

solve 1 and 2

x+y= 40

14x+ 12y=  720

from 1

x= 40-y

put this in 2 in place of x

14(40-y)+12y= 720

560-14y+12y= 720

collect like terms

-2y= 720-560

-2y= 160

y= -160/2

y= -80

put y= 80 in 1

x+80= 40

x= 40-80

x= -40

Hence Adult tickets cost $80, children ticket cost $40

Answer:

Step-by-step explanation:

slope of red line=(-4-4)/(2-0)=-8/2=-4

eq. of red line is y-4=-4(x-0)

y=-4x+4

put x=0,y=0

0=0+4

which is true if 0<4

so y<-4x+4

The linear inequality represents the graph fr the coordinates (0,4), (2,-4) is y < -4x + 4.

Expressions with linear inequalities compare any two values using inequality symbols like "<",  ">" , "≤" or "≥" These values could be either numerical, algebraic, or both.

Calculation for linear inequality shown by graph:

The coordinates of the straight line are  (0,4), (2,-4).

Substitute the value in equation shown in option C.

y < -4x + 4

For points (0,4), put x = 0 and find y.

y < -4×0 + 4

y = 4 , which is satisfied.

Now consider points (2, -4)

Put x = 2 in the same equation and find y.

y < -4×2 + 4

y = -4 ( which again satisfies the given value for y)

Therefore, the equation y < -4x + 4 satisfies the points given for straight line.

Answer:

1.2%

Step-by-step explanation:

Solving our equation

r = 10.2 / ( 425 × 2 ) = 0.012

r = 0.012

converting r decimal to a percentage

R = 0.012 * 100 = 1.2%/year

The interest rate required to
