Answer:

the answer is 90° because you need to figure out the degree.

Step-by-step explanation:

2 and 3 equals to 6 .

That's how you got that.

Don't know exactly what you're asking, but I think you're asking what the slope and what the y-intercept is.

1/2x is the slope

Positive 2 is the y-intercept

it y because of the equation mx +b and b is y

Answer:

Step-by-step explanation:

Let the initial percentage to be 30%

If it started to loose 2.5% every hour where;

t represents the time after Charlotte left her house

The amount of percent remaining every hour will form an arithmetic sequence as shown;

30, (30-2.5), (30-5.0),...

30, 27.5, 25.0...

Using the nth term for calculating an arithmetic sequence

B = a + (t-1)d

a is the first term = 30

d is the common difference = 27.5-30 = 25-27.5 = -2.5

t is the time

Substitute the given values into the formula;

B = 30 + (t-1)(-2.5)

B = 30+(-2.5t+2.5)

B = 30-2.5t+2.5

B = 32.5 - 2.5t

Hence equation for B, in  terms of t, representing the charge remaining in Charlotte's battery, as a percentage,  t hours after Charlotte left her house is B = 32.5 - 2.5t

Answer:

$6.00

Explanation:

10% of 200 is 20

20/30 = $.6666

Each parent gets $0.67 off.

$200/30 = $6.6666

$6.6666 ---> $6.67

6.67 - 0.67

= 6.00

Check:

6.00 * 30 = 180

200-180 = 20

Answer:

Each parent pays an amount of £6.

Step-by-step explanation:

Cost of the hall = £200

Discount for parents = 10%

Cost of the hall for parents

= 200 - 10% of 200

= 200 - 10/100 × 200

= 200 - 10 × 2

= 200 - 20

= £180

If 30 parents share the cost equally,

Each parent has to pay

180/30

= 18/3

= 6

Answer:

a. sine StartFraction pi Over 3 EndFraction = StartFraction opposite Over hypotenuse EndFractionEquals StartFraction opposite Over 1 EndFraction  Equals opposite

The length opposite the angle is the vertical distance from the x-axis on the graph.

Step-by-step explanation:

sin (π/3) = opposite/hypotenuse = opposite/1; The length opposite the angle is the vertical distance from the x-axis on the graph.

Unit circle is a circle centered at the origin, (0,0) with radius(r) i.,e r= 1.

The angle π/3 forms an arc of length S and the x-axis and y-axis divide the coordinate plane and the unit circle as it is centered at (0.0).

Also, the terminal side intersect the circle at (x, y). Thus;

sin (π/3) = opposite/hypotenuse = opposite/1

Thus;

sin (π/3) = opposite

Also, the length opposite the angle is the vertical distance from the x-axis on the graph.

Answer:

6.45 feet

Step-by-step explanation:

He starts 17 and 1/2 feet off the ground

Elevation relative to ground: 17 1/2

Then he increases the height by 4 and 3/4

Expression: 17 1/2 +4 3/4

Elevation relative to ground: 22 1/4

Next he decreases the elevation by 15.8 feet

Expression: 22.25-15.8

Elevation relative to ground: 6.45

The answer 6.45 feet from the ground

Answer:

i know a good trick on how to do this.

Step-by-step explanation:

The number 4 is apart of the sequence, but it has been taken away by 3.

3+4=7. Since it was taken away by 3, we have to add 7 by 3 to get 9. So on and so forth.

Answer:

y=2x+2

Step-by-step explanation:

Use the method rise overrun from 0,2 to 2,6 it rises 4 and runs 2(moves positively on the x-axis). divide 4 by 2 and get 2.

then check the y-intercept( when x is 0 on y-axis) the y intercept is 2

then plug in y=slope(x)+b(intercept)

to get y=2x+2.

Answer: $3678.36

Step-by-step explanation:

New airball hockey table = $875.23

pinball machine = $622.19

2 arcade racing games = $942.49 each.= $942.49 × 2 = $1884.98

Total amount without sales tax will be:

= $875.23 + $622.19 + $1884.98

= $3382.4

Sales tax = 8.75% × $3382.4

= 0.0875 × $3382.4

= $295.96

Total cost = $3382.40 + $295.96

= $3678.36

Answer:

Option A

Step-by-step explanation:

to be perpendicular, the product of two slopes should be -1

the slope of the first equation is 1/5, so the slope should be -5

(1/5) (-5)= -1

y= -5x +b

Substitute (1,1) to solve for b,

b= 6

Thus, the equation is y= -5x +6

Answer:

C. c = 64

Step-by-step explanation:

The question is incomplete. Here is the complete question.

What value of c makes the equation true? Assume x greater-than 0 and y greater-than 0

RootIndex 3 StartRoot StartFraction x cubed Over c y Superscript 4 Baseline EndFraction EndRoot = StartFraction x Over 4 y (RootIndex 3 StartRoot y EndRoot) EndFraction

c = 12

c = 16

c = 64

c = 81

Given the function;

[tex]\sqrt[3]{\dfrac{x^3}{cy^4} } = \dfrac{x}{4y\sqrt[3]{y} }[/tex]

We are to find the value of c from the expression.

Step 1: Take the cube of both sides;

[tex](\sqrt[3]{\dfrac{x^3}{cy^4} } )^3= (\dfrac{x}{4y\sqrt[3]{y} })^3\\\dfrac{x^3}{cy^4} = \dfrac{x^3}{(4y)^3(\sqrt[3]{y} )^3}\\\dfrac{x^3}{cy^4} = \dfrac{x^3}{(64y^3)(y)}\\\\\dfrac{x^3}{cy^4} = \dfrac{x^3}{64y^4}\\[/tex]

Step 2: compare the denominator of both sides of the equation;

[tex]\dfrac{x^3}{cy^4} = \dfrac{x^3}{64y^4}\\\\On \ comparing;\\\\cy^4 = 64y^4\\[/tex]

Step 3: Divide both sides by y₄

[tex]\dfrac{cy^4}{y^4} = \dfrac{64y^4}{y^4}\\c = 64\\[/tex]

Hence the value of c is 64. Option C is correct

Answer:

-8

Step-by-step explanation:

12<-3 (x + 4)

1. distribute to the -3 to the x and 4 and should get

-3*x = -3x

-3*4 = -12

12< -3x - 12

2. now you get rid of the common factors which is -12 so add 12 to both sides and should get

-12+12=0

12+12=24

24< -3x

3. to get x by itself you will have to get rid of -3, so how to do that is divide -3 to both side and should get

-3x/-3= x

24/-3= -8

-8<x
