The actual distance between cities is 580 miles.

Step-by-step explanation:

Map distance = 7\frac{1}{4} inches = \frac{29}{4}\ inches

Scale used;

\frac{1}{2}\ inches = 40\ miles

Multiplying both sides by 2

2*\frac{1}{2}=40*2\\1\ inch = 80\ miles\\

Now,

\frac{29}{4}\ inches = \frac{29}{4}*80\\\\\frac{29}{4}=29*20\\\\\frac{29}{4}\ inches = 580\ miles

The actual distance between cities is 580 miles.

A cylindrical tank has a diameter of 2.5 feet and a height of 4.8 feet. what is the lateral surface area of the tank to the near
blsea [12.9K]

Answer:

This is approximately 37.7 ft^{2} to the nearest hundredth

Step-by-step explanation:

First of all, we will need to understand that to find the lateral surface area of the cylinder, we simply need to multiply the circumference of the circular base by the height of the cylinder.

In this case, the circumference of the circular base can be obtained by the formula

2 \pi r

Hence we will have the circumference as 2 \times \pi \times \frac{2.5}{2}=7.85 feet

Tp get the Lateral area, we will simply have to multiply this value (7.85 feet )

by the height (4.8 feet)

7.85 X 4.8 =37.68 feet ^{2}

This is approximately 37.7 ft^{2} to the nearest hundredth

Solve the expression 2(10)+2(x-4) show your work
Nataliya [291]

Answer:

12 + 2x

Step-by-step explanation:

<em>simplifying</em><em> </em><em>expression</em><em>:</em>

2(10) + 2(x-4)

2 × 10 = 20

2 × x = 2x

2 × -4 = -8

20 + 2x - 8

20 - 8 = 12

12 + 2x

<em>if you want to simplify it</em><em> </em><em>more</em><em>:</em>

(12/2) + (2x/2)

2(6 + x)

<em>if you want to solve for x:</em>

12 + 2x = 0

(12 - 12) + 2x = (0 - 12)

2x/2 = -12/2

x = -6

hope this helps you!

Kale works in a packaging factory that has 900 employees. By the end of the day they manage to package 3.2x 10^5 products what i
leva [86]
First let’s take this out of scientific notation 320000 products are packaged. Divide that by 900(amount of employees) and you get 355.55555 repeating. In scientific notation you’d move the decimal two to the left to make it 3.5 X 10^2
