4) The diameter of a circle is 32m. The radius is represented by 4(x + 2).

vaieri [72.5K]

Answer:

The value of x is 2

Step-by-step explanation:

Diameter = 2r -------------------------------------------------------------------(1)

where r is the radius

The value of the diameter = 32 m and radius is given to be 4(x+2)

substitute the above into equation (1) and then solve for x

32 = 2 [ 4(x + 2)]

first open the inner bracket

32 = 2[4x + 8}

then open the outer bracket

32 = 8x + 16

subtract 16 from both-side of the equation

32 - 16 = 8x +16 - 16

16 = 8x

Divide both-side of the equation by 8

16/8 = 8x/8

2 = x

x = 2

Therefore, the value of x is 2

A traffic engineer monitors the rate at which cars enter the main highway during the afternoon rush hour. From her data she esti

sertanlavr [38]

Answer:

On average, cars enter the highway during the first half hour of rush hour at a rate 97 per minute.

Step-by-step explanation:

Given that, the rate R(t) at which cars enter the highway is given the formula

$R(t)= 100(1-0.0001t^2)$

The average rate of car enter the highway during first half hour of rush hour is the average value of R(t) from t=0 to t=30.

$\therefore \int_0^{30} 100(1-0.0001t^2)\ dt$

$=[100(t-0.0001\frac{t^3}{3})]_0^{30}$

$=100[(30-0.0001\frac{30^3}{3})-(0-0.0001\frac{0^3}{3})]$

=2901

The average rate of car is $=\frac{\textrm{The number of car}}{Time}$

$=\frac{2910}{30}$

=97

On average, cars enter the highway during the first half hour of rush hour at a rate 97 per minute.

Please if anyone could help me with this questions??

Answer:

Question 5

a)Simple Interest = Nu 450, Total Amount = Nu 6,450

b)Simple Interest = Nu 250, Total Amount = Nu 12,750

c)Simple Interest = Nu 2,880, Total Amount = Nu 10,880

Question 6

The amount of commission Mindu earned was Nu 4,750

Step-by-step explanation:

Question 5

Simply Interest formula is given as

I = P × R × T

Total Amount = P + I

Where

P = Principal

R = Rate

T = Time in years

I = Interest

a) P = Principal = Nu 6000

R = Rate = 15% = 0.15

T = Time = 6 months , converting to years = 6/12 months = 0.5years

I = Interest = 6000 × 0.15 × 0.5

I = Nu 450

Amount = P + I

= Nu 6000 + Nu 450

= Nu 6,450

Simple Interest = Nu 450, Total Amount =Nu 6,450

b) P = Principal = Nu 12,500

R = Rate = 8% = 0.08

T = Time = 3 months , converting to years = 3/12 months = 0.25 years

I = Interest = 12,500 × 0.08 × 0.25

I = Nu 250

Amount = P + I

= Nu 12,250 + Nu 240

= Nu 12,750

Simple Interest = Nu 250, Total Amount =Nu 12,750

c) P = Principal = Nu 8000

R = Rate = 12% = 0.12

T = Time = 3years

I = Interest = 6000 × 0.12 × 3

I = Nu 2,880

Amount = P + I

= Nu 8000 + Nu 2,880

= Nu 10,880

Simple Interest = Nu 2,880, Total Amount = Nu 10,880

Question 6

We are told in the question that each month:

If sales are up to Nu 75,000, = Mindu earns 3% commission

If sales are over Nu 75,000 = Mindu earns 5% commission

Last month, Mindu has sales of Nu 95,000

Since his sales was above Nu 75,000 he earns a 5% commission

Therefore, the amount he earned as commission is calculated as:

Nu 95,000 × 5%

= Nu 4,750

Therefore, the amount of commission Mindu earned was Nu 4,750

viva [34]

Answer:

hailey played the game longer (1/3 hour).

Step-by-step explanation:

You are deciding which is greater: 1/6 or 1/3.in this case, a smaller denominator (such as 3) produces a greater value.1/3 has a smaller denom. than does 1/6, so 1/3 is greater than 1/6.hailey played the game longer (1/3 hour).
