Answer: 1.05 ·10⁴ mosquitoes

Step-by-step explanation:

1,000mosquitoes/hour x 10.5hours =10,500 mosquitoes

Now you have to move decimal point as many space as needed left so that the number is less than ten.

10,500 ↪ 1.0500 because I moved decimal point 4 spaces, its 10⁴

Answer: 1.05 ·10⁴ mosquitoes

How tall is the flag pole (please give explanation too)
Tpy6a [65]

Answer:

  22 3/4 ft

Step-by-step explanation:

The diagram seems to show a 6 1/2 ft person casting a 9 ft shadow at the same time a flagpole is casting a 31 1/2 ft shadow. You want the height of the flagpole.

<h3>Proportion</h3>

Shadow lengths are presumed proportional to the height of the object making them. This means ...

  h/(31 1/2) = (6 1/2)/9 . . . . . all lengths in feet

Multiplying by 31 1/2, we get ...

  h = (31 1/2)(6 1/2)/9 = (819/4)/9 = 91/4

  h = 22 3/4 . . . . ft

The flagpole is 22 3/4 feet tall.

A few students conducted a study on how many peanuts it would take to completely fill a jar. They had the following data to help
Marizza181 [45]

Answer:

370 peanuts

Step-by-step explanation:

65/108 = 0.60185

90/150 = 0.6000

In each case, the number of peanuts is either exactly or very close to 60% of the volume.

A cylinder with radius 3.5 cm and height 16 cm has volume:

V = (pi)r^2h

V = (3.14159)(3.5 cm)^2(16 cm)

V = 615.752 cm^3

We take 60% of the volume to estimate the number of peanuts.

60% * 615.752 cm^3 = 369.451

Answer: 370 peanuts

dem82 [27]

Answer: R(t) = 750 + 0.04t

Step-by-step explanation:

Here's the complete question:

Ebuka's monthly rent is $750. If Ebuka pays the rent late, his landlord charges 4% interest per week that the payment is late. Write a function that gives the total cost R(t), in dollars, of Ebuka's rent if he pays it t weeks late.

The above question will be represented by:

R(t) = $750 + (4% × t)

R(t) = 750 + (4/100 × t)

R(t) = 750 + 0.04t
