Answer:

36 liters

Step-by-step explanation:

We solve this question using the least common multiple method

Find and list multiples of the liter the blue paint comes in the liters the yellow paint comes in. We find the first common multiple is found. This is the least common multiple.

Multiples of 9:

9, 18, 27, 36, 45, 54

Multiples of 12:

12, 24, 36, 48, 60

Therefore,

LCM(9, 12) = 36

Hence, the smallest amount of each paint color the store must have sold is 36 liters

Step-by-step explanation:

Answer:

7.68h

38.4 + 7.68h

Step-by-step explanation:

Earnings per hour = $7.68

This week Kaley worked 5 more hours than Tom in overtime

h = number of hours Tom worked.

Tom's total earnings for the week = earnings per hour × number of hours

= $7.68 × h

= 7.68h

Tom's total earnings for the week = 7.68h

Kayley's total earnings for the week = earnings per hour × number of hours

He works 5 hours more than Tom in overtime.

Tom = h

Kayley = 5 + h

Kayley's total earnings for the week = earnings per hour × number of hours

= (7.68) × (5 + h)

= 38.4 + 7.68h

Kayley's total earnings for the week =

38.4 + 7.68h

Step-by-step explanation:

[tex]24^{2} + 7^{2}[/tex] = 625

[tex]\sqrt{625\\}[/tex] = 25

Therefore, the length of BD in rectangle ABCD is 25mm. I just did the test and it is correct. 23 is wrong.

Answer:

y = x - 600

Step-by-step explanation:

y = mx + b , "m" is slope and "b" is y-intercept

y - [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex])

~~~~~~~~~~~~~

y-intercept is (0, - 600) and x-intercept is (600, 0)

The slope is 1

y + 600 = x - 0

y = x - 600

Answer:

Rate of inflation = 1.4%

Step-by-step explanation:

Given:

Nominal interest rate = 4.2%

Real interest rate = 2.8%

Find:

Rate of inflation

Computation:

Rate of inflation = Nominal interest rate - Real interest rate

Rate of inflation = 4.2% - 2.8%

Rate of inflation = 1.4%

Answer:

x= 12

Step-by-step explanation:

The sum of both of the equasions equal up to 180. so you set up the problem like this:

(9x-4)+(6x+4)=180

15x=180

x=12

To check;

(9(12)-4)+(6(12)+4)=180

104+76=180

Answer:

a.  The car sweeps out 0.799 radians per second.

b. f(t) = 8 cos (0.799t)

Step-by-step explanation:

Given that:

The radius r = 8 feet

a.

The time t it takes to complete one full lap = 7.854 seconds

Recall that:

Angular velocity ω = 2π / t

So if in 7.854 seconds, the car sweeps = 2π radian

∴

per second, the car will sweep ω  = 2π/ 7.854

ω = 0.799 rad/sec

Thus, the car sweeps out 0.799 radians per second.

b.

Since, r = 8 feet.

Suppose the car travels an angle θ in time (t),

Then the general equation for the horizontal component is:

f(t) = rcos( ωt)

f(t) = 8 cos (0.799t)

The true statements are:

The given parameters are:

To do this, we simply calculate the angular velocity as follows:

[tex]\omega = \frac{2\pi}{T}[/tex]

Substitute 7.854 for T

[tex]\omega = \frac{2\pi}{7.854}[/tex]

Simplify

[tex]\omega = 0.255 \pi[/tex]

Hence, the car swept out [tex]0.255 \pi[/tex] radians per seconds

To do this, we simply make use of the general equation for the horizontal component as follows:

[tex]f(t) = r\cos( \omega t)[/tex]

Substitute 8 for r

[tex]f(t) = 8\cos( \omega t)[/tex]

Substitute [tex]\omega = 0.255 \pi[/tex]

[tex]f(t) = 8\cos( 0.255\pi t)[/tex]

Hence, the function f that determines the car's distance at time t is: [tex]f(t) = 8\cos( 0.255\pi t)[/tex]

Answer:

- 1020

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 12 and d = a₂ - a₁ = 0 - 12 = - 12 , thus

a₈₇ = 12 + (86 × - 12) = 12 - 1032 = - 1020
