dsp73

Answer:

The value of x is <u>1</u><u>0</u><u>.</u>

Step-by-step explanation:

By question,

-4(x - 5) = 60

or,-4x + 20 = 60

Amir wants to do a full painting on the surface of a pottery. The pottery is in the shape of a cylinder with a height of 14 cm a
Radda [10]

Answer:

About 66 tubes

Step-by-step explanation:

Cylinder surface area formula: 2πr(h + r) where h = height and r = radius

In this case, h = 14, π = 3.14 and r = 4.5 so the surface area of one pottery is:

2 * π * 4.5 * (14 + 4.5) = 166.5π ≈ 523.08

The surface area of 15 potteries would be 523.08 * 15 = 7846.2 so it would take 7846.2 / 120 = 65.385 ≈ 66 tubes. We round to the nearest integer because in this context, you can only have integer values of tubes, you can't have, say, 0.5 tubes.

For the given situation identify the independent and dependent variables and then find a reasonable domain and range of values .
Mademuasel [1]

Answer:

D. is false

Step-by-step explanation:

The first thing is to define and find each of the things they ask us for:

 -Independent variable: It is the variable that does not depend on another value, that is, it would be the value to be defined. In the particular case, it would be the amount of gasoline to recharge.

 -Dependent variables: It is the variable that depends on the independent variable, its value depends on another value. In this particular case, then it would be the distance that can be traveled.

 -Domain: It is the value series, which can take the independent variable, in this case it is restricted by the vehicle's gas tank. The domain in this case is 0 to 2.5 gallons.

-Range: It is the series of values ​​that the distance the vehicle can travel, is determined by the gasoline performance of the vehicle and limited by the amount of fuel. The range in this case is from or up to 162.5 (65 * 2.5) miles.

Based on this statement, A, B and C are correct.

Statement D is not related to the statement, and we already know what the dependent variable actually is.
