Answer:

65 + .70(20)= 79 dollars

Step-by-step explanation:

65+0.70miles = Fee

this means she can drive 19 miles and she will still be below the price company A but as soon as she drives 20 miles company A and B will cost the same

Answer:

see explanation

Step-by-step explanation:

(a)

[tex]\frac{3}{7}[/tex] a × - [tex]\frac{21}{15}[/tex] b ( cancel 3 and 15 and 7 and 21 )

= a × - [tex]\frac{3}{5}[/tex] b

= - [tex]\frac{3}{5}[/tex] ab

(b)

3xy(5x²y² - 4yz) ← multiply each term in the parenthesis by 3xy

= 15x³y³ - 12xy²z

Answer:

[tex]Time \ in\ school = \frac{3}{8} \ of \ the \ day[/tex]

                      = [tex]\frac{3}{8} \times 24 = 9 \ hours \ in \ school[/tex]

[tex]Time \ in \ class = \frac{2}{3} \ of \ the \ time \ in \ school = \frac{2}{3} \times 9 = 6 \ hours \ in \ class[/tex]

1 hour = 60 minutes

Therefore, 6 hours = 360 minutes

So , 360 minutes they spent doing mathematics.

Answer:

80 minutes

Step-by-step explanation:

1. Determine the volume of the tank

volume = length x width x height

100 cm = 1 meter

80cm /100 = 0.8m

1.2 x 1 x 0.8 = 0.96m³

2. convert litre to meter

1 liter = 0.001 m

2 litres = 0.002m

3. determine the time it would take to fill 0.96m

(0.96x 10) / 0.002 = 4800 seconds

4. convert seconds to minutes

60 seconds = 1 minute

4800 seconds / 60 = 80 minutes

2l = 0.0

Answer:

2400

Step-by-step explanation:

3 times 8 is 24

24 added by two zeros is 2400

Step-by-step explanation:

Answer:

y = -190 cos(π t / 120) + 195

Step-by-step explanation:

General form of a sinusoidal function: y = A cos(Bt - C) + D

Now generally a cosine function starts at the maximum value, so to start at the minimum value, flip the cosine function by making it negative.

A is the amplitude of the curve and will be the radius of the ferris wheel. Therefore, A = 380 / 2 = 190 feet.

2π / B is the period of the curve and will be the time to complete one full rotation. The time to complete one full rotation is given as 4 minutes. Convert this into seconds to get period = 4 minutes * (60 seconds / minute) = 240 seconds. Therefore, B = 2π / period = 2π / 240 seconds = π / 120.

C/B is the phase shift, or horizontal shift of the graph. Since the negative cosine function already starts at the minimum value, there is no phase shift so C/B = 0, meaning C = 0.

D is the vertical shift and will be the height of the center of the ferris wheel. Therefore, D = 195 feet.

Your final function will be:

y = -190 cos(π t / 120) + 195

Answer: $2400

Step-by-step explanation:

Given

Maria got a hike of 3%.

After the hike she earns $2472 each month

Suppose, before hike she earns x each month

[tex]\Rightarrow x+x\times 3\%=2472\\\Rightarrow x(1+0.03)=2472\\\Rightarrow 1.03x=2472\\\Rightarrow x=\$2400[/tex]

Thus, she earns $2400 before the hike.

Answer:

Step-by-step explanation:

first you add 6 + 7 = 13

then you 13 - 2 which gives you eleven!

Answer:

62 degrees

Step-by-step explanation:

The angle is an inscribed angle, so its measure is half the measure of the intercepted arc.

Said another way, the intercepted arc is twice the measure of the inscribed angle.

2 x 31 = 62

Answer:

D

Answer:

x = 25

Step-by-step explanation:

40 is a vertical angle equal to the angle to the right of 2x.

2x, 40, and 90 are supplementary angles (they add up to 180)

2x + 40 + 90 = 180

2x + 130 = 180

2x = 180 - 130

2x = 50

x = 25

they are right

Answer:

a=170

Step-by-step explanation:

180-6=174mil

round to 170.

Answer:

4.9 (rounded)

Step-by-step explanation:

a^2 + 1^2 = 5^2

a^2 + 1 = 25

      - 1     - 1

= a^2 = 24

[tex]\sqrt{a^2 = 24}[/tex] = 4.9 (rounded)

congratulationsssssssss

Answer:

See below.

Step-by-step explanation:

Remember SOHCAHTOA.

Soh...

Sine = Opposite / Hypotenuse

...cah...

Cosine = Adjacent / Hypotenuse

...toa

Tangent = Opposite / Adjacent

sin(64) = x / 94

Multiply both sides by 94.

94sin(64) = 94x / 94

Simplify

x = 94sin(64)

x = 84.487 = 84.5

Step-by-step explanation:

Given

[tex]Scale\ length = 8ft[/tex]

Required

Determine the scale of the drawing

The question is incomplete, as the actual width of the kitchen is not given. The general explanation, however, is as follows:

The scale of a drawing is represented as:

[tex]Scale = Scale\ Measurement : Actual\ Measurement[/tex]

This gives:

[tex]Scale = 8ft : Actual[/tex]

Assume the actual length of the kitchen is 24ft.

The equation becomes:

[tex]Scale = 8ft : 24ft[/tex]

Divide by 8ft

[tex]Scale = 8ft/8ft : 24ft/8ft[/tex]

[tex]Scale = 1 : 3[/tex]

The answer is 612

Answer:

Logan can mow 1 lawn per hour more than Brian

Step-by-step explanation:

Given

[tex]Logan: 8\ lawns \to 4\ hours[/tex]

See attachment for Brian's graph

First, calculate Logan's hourly rate

[tex]Rate = \frac{Lawn}{Time}[/tex]

[tex]Rate = \frac{8\ lawns}{4\ hours}[/tex]

Rate = 2 lawns per hour

To calculate Brian's rate, we select 2 points from the linear graph

[tex](x_1,y_1) = (1,1)[/tex]

[tex](x_2,y_2) = (2,2)[/tex]

So, the rate is:

[tex]Rate = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]Rate = \frac{2 - 1}{2 - 1}[/tex]

[tex]Rate = \frac{1}{1}[/tex]

Rate = 1 lawn per hour

So, we have:

[tex]Logan = 2[/tex]

[tex]Brian = 1[/tex]

Calculate the difference (d)

[tex]d = Logan - Brian[/tex]

[tex]d = 2 - 1[/tex]

[tex]d = 1[/tex]

Logan can mow 1 lawn per hour more than Brian

Answer:

∠ A ≈ 75.7°

Step-by-step explanation:

Given

[tex]\frac{sinA}{8}[/tex] = [tex]\frac{sin58}{7}[/tex] ( cross- multiply )

7 × sinA = 8 × sin58° ( divide both sides by 7 )

sinA = [tex]\frac{8sin58}{7}[/tex] , then

∠ A = [tex]sin^{-1}[/tex] ([tex]\frac{8sin58}{7}[/tex] ) ≈ 75.7° ( to the nearest tenth )

Answer:

  see attached

Step-by-step explanation:

The equation can be rewritten to vertex form, so you can tell the vertex is at (2, -5). The leading coefficient of 2 means the points will be twice as far apart vertically than they would be if the leading coefficient were 1. A couple of points are shown in the attached.

  y = 2(x^2 -4x) +3

  y = 2(x^2 -4x +4) +3 -8 . . . . . . complete the square

  y = 2(x -2)^2 -5 . . . . . . . . . . . . finish putting in vertex form
