Answer:

7.38 minutes

Step-by-step explanation:

Given

Distance= 8km

speed = 65km/h

Time=?

From physics,

Speed= distance/ time

Then substitute the values to find time

65= 8/ time

Time= 8/65

=0.1231 hrs

To Convert to minutes

1hr= 60 mins

0.1231 hrs = X minutes

Cross multiply, we have

X minutes=( 0.1231 × 60)/1

= 7.38 minutes

Hence, it takes 7.38 minutes for him to cover this distance

Answer:

26cm²

Step-by-step explanation:

Perimeter

2x - 4 + 5x - 13 + x + 9 = 40

8x - 8 = 40

8x = 40 - 8

8x = 32

x = 4

Sides of the triangle

Height = 2x - 4 = 2 x 4 - 4 = 4cm

Hypotenuse = 5x - 13 = 5 x 4 - 13 = 7cm

Base = x + 9 = 4 + 9 = 13cm

Area of triangle

= 1/2 x base x height

= 1/2 x 13 x 4

= 26cm²

Hope this helps

stira [4]

Step-by-step explanation:

The river is 1000 m wide, and the boat moves at 3 m/s, so the time it takes to cross the river is:

t = (1000 m) / (3 m/s)

t = 333.3 s

The river flows at 2 m/s, so by the time he reaches the other bank, he drifts downstream a distance of:

d = (2 m/s) (333.3 s)

d = 666.7 m

A dinner cost $22 and a sales tax of $1.87 was added to the bill. How much would the sales tax be on a $66 dinner? What is the t
alexdok [17]

Answer:

The correct answer is the sales tax charged is $5.61 for $66 dinner at 8.5% tax rate.

Step-by-step explanation:

Cost of the dinner is $22. Tax levied on it is $1.87

Let x% is the rate of tax in the city.

Therefore, x% of 22 = 1.87

⇒ x = 1.87 × \frac{100}{22} = 8.5

Therefore 8.5% is the tax rate in the city on foods.

Now another dinner costs $66.

Tax levied on it at the same percentage is given by 8.5% of 66 = $5.61.

Thus $5.61 as sales tax would be charged for a $66 dinner.
