[tex] Distance = 160km[/tex]

Step-by-step explanation:

According to the Question ,

We know the formula of speed as ,

[tex]\implies Speed \times Time = Distance \\\\\implies Distance = 80km/hr \times 2hr \\\\\implies \boxed{\boxed{ Distance = 160\ km}}[/tex]

Answer:

$1800

He owes them $900 each

Step-by-step explanation:

Profit = Revenue -  (fixed cost + material cost)

fixed cost $400 x 2 = 800

4900 - (800 + 1400) = $2,700

Since they share the profits equally, each would get 2700/3 = 900

Answer:

1. 53

2. 20

3. 37

4. 29

Step-by-step explanation:

Since your trying to find the hypotenuse you equation is...

1. 28^2 + 45^2 = C^2

    784 + 2025 = C^2

      Square Root 2809= C^2

    C=53

So after you square root 2809 you get 53.

2. 12^2 + 16^2 = C^2

     144 + 256 = C^2

      Square Root 400 = C^2

    C=20

So after you square root 400 you get 40.

3.  12^2 + 35^2 = C^2

    144 + 1225 = C^2

    Square Root 1369 = C^2

   C=37

So after you square root 1359 you get 37.

4. 20^2 + 21^2 = C^2

   400 + 441 = C^2

  Square root 841 = C^2

  C=20

So after you square root 841 you get 29.

30 years and a half

Step-by-step explanation:

well let's just say 3.5k x hmm 2? at an estimate and that will get us to 7000.. so in order to get to 7000 we have to wait 15 years which is 30 years and a half. From Xthermyx. A brainly user.

It would take 22.7 years for the value of the account to reach $7,700.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Since the money in the account is doubling every 15 years.

The following equation is used to find the time it takes to reach a certain value:

t = (ln(P/F))/(ln(1+r))

where:

P = the initial investment amount

F = the future value we want to reach

r = the growth rate per period

ln = natural logarithm

t = the number of years it takes to reach F

P = $3,500

F = $7,700

r = ln(2)/15 (since the money is doubling every 15 years).

Plugging these values into the equation.

t = (ln(3500/7700)) / (ln(1+ln(2)/15))

t = ln (5/11) / ln (1 + 0.30/15)

t = 22.7

Therefore,

It would take 22.7 years for the value of the account to reach $7,700.

Answer:

FV= $70,887.15

Step-by-step explanation:

First, we need to calculate the future value of the $130 deposit for 5 years:

FV= {A*[(1+i)^n-1]}/i

A= monthly deposit= $130

i= 0.08/12= 0.0067

n= 5*12= 60 months

FV= {130*[(1.0067^60) - 1]} / 0.0067

FV= $9,561.96

Now, using the following formula, the future value of the investment after 25 years:

FV= PV*(1 + i)^n

n= 25*12= 300

FV= 9,561.96*(1.0067^300)

FV= $70,887.15

Answer:

300$

I=P×r×t

P= is the principal amount, $6000.00.

r=is the interest rate, 5% per year (you have to put it in decimal form to multiply)

t= is the time involved, which is 1 year

To find interest multiply 6000 × 0.05 × 1

Answer:

1. He spent $360

2. Amount left over = $440

Step-by-step explanation:

Let us first layout the important details in the question:

Amount earned = $800

percentage spent on travel expenses = 45% of the amount earned

45% of the amount earned

[tex]= \frac{45}{100} \times 800\\= 0.45 \times 800 = 360[/tex]

∴ Amount sent on travel = $360

To find the amount of money left over, we will simply deduct the amount spent from the total earned amount. This is done as follows:

Amount left over = Amount earned - Amount spent on travel

Amount left over = 800 - 360 = $440

∴ $440 was left over

Can you post the picture pls

Step-by-step explanation:

Answer:

Acceleration is 0.5 m/s² and the distance covered is 6.25 m.

Step-by-step explanation:

Given that,

Initial speed, u = 0

Final speed, v = 9 km/h = 2.5 m/s

Time, t = 5 seconds

We need to find the acceleration and the displacement covered in that time. Acceleration = rate of change of velocity

So,

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{2.5-0}{5}\\\\a=0.5\ m/s^2[/tex]

Distance d can be calculated using third equation of motion.

[tex]d=\dfrac{v^2-u^2}{2a}\\\\d=\dfrac{2.5^2-0^2}{2\times 0.5}\\\\d=6.25\ m[/tex]

So, acceleration is 0.5 m/s² and the distance covered is 6.25 m.

Answer:

706.3 cm³

Step-by-step explanation:

Given

"The cone and cylinder above have the same radius and height..."

the volume of the cone = 210 cubic centimeters

Formula

The formula for the volume of a cylinder is V=Bh or V=πr2h. The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h.

How to solve

Given radius and height calculate the volume, lateral surface area, and total surface area.

Calculate V, L, A | Given r, h

use the formulas above

Given radius and volume calculate the height, lateral surface area, and total surface area.

Calculate h, L, A | Given r, V

h = V / πr2

Given radius and lateral surface area calculate the height, volume, and total surface area.

Calculate h, V, A | Given r, L

h = L/2πr

Given the height and lateral surface area calculate the radius, volume, and total surface area.

Calculate r, V, A | Given h, L

r = L/2πh

Given height and volume calculate the radius, lateral surface area, and total surface area.

Calculate r, L, A | Given h, V

$r = √( V / πh )

Answer:

42. x = 25

43. LM = 11

Step-by-step explanation:

For 42, the three angles of a triangle, when added, = 180 degrees. We know that one of the angles is 90 degrees...a right angle.

So: 90 + 2x + x + 15 = 180

105 + 3x = 180

3x = 75

x = 25

If they ask for more information: the three angles are 90 degrees, 50 degrees (2x), and 40 (x + 15). 90 + 50 + 40 = 180

For 43, ray PN bisects (cuts in equal halves) the triangle. We know this because the two segments LP and PM are equal. As a result, the triangles LPM and PNM are mirror images. Since MN = 11, LM also = 11.
