Answer:

x = 19

Step-by-step explanation:

6x+4 + 4x - 14 = 180

10x - 10 = 180

10 X = 190

x = 19

The scale on a map shows that 5 centimeters = 2 kilometers.

ryzh [129]

5 cm = 2km

Scale= 5 cm : 200000 cm

= 1 : 40000

a. 1 : 40000 = x : 500000

x = 12.5 cm

b.1 : 40000 = 2 : x

x = 80000 cm

x = 0.8 km

Two cylinders are shown below. Which cylinder has the greater volume? Use 3.14 for π. Round to the nearest hundredth. Use the dr

Lemur [1.5K]

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

To find which cylinder has the greater volume, we need to find out the volume of each one.

As we all know that the formula used to determine the volume of a cylinder is:

V = The base area*the height

<=> V = π $r^{2}$ h (cubic units)

For example, in my attached photo, we will use this formula to find the volume of each one.

1. Cylinder A:

The base area = π $r^{2}$ = π $3.5^{2}$ = 38.46 square in

The height = 8.5 in

=> the volume of Cylinder A

= The base area*the height

= 38.46*8.5

= 326.91 cubic in

2. Cylinder B:

The base area = π $r^{2}$ = π $2.7^{2}$ = 22.89 square in

The height = 11 in

=> the volume of Cylinder A

= The base area*the height

= 22.89*11

= 251.79 cubic in

Hence, Cylinder B has the greater volume

Can you explain how to do this

zaharov [31]

Answer:

-18x+89

Step-by-step explanation:

Here's why simple to simplify this expression we heave to first get rid of the parentheses so we distribute the 9. So we get:7-18x+81+1.

Now we can simplify easily:-18x+89
