Answer:

Commutative Property of Addition.

Step-by-step explanation:

Given : 3.2 + 4 = 4 + 3.2

To find : Which property is illustrated by the statement.

Solution : We have given

3.2 + 4 = 4 + 3.2

Commutative Property of Addition : if changing the order of the operands does not change the result.

Example : a + b = b + a

2 +3 = 3+2 = 5.

So, We can see 3.2 + 4 = 7.2

4 + 3.2 = 7.2

So, the sum is same after changing the order .

Therefore, Commutative Property of Addition.

4+p over 14 = 1 need help

lukranit [14]

Answer:

p = 10

Step-by-step explanation:

In order to solve an equation we must isolate the variable we're solving for, p.

We can do this by undoing operations in the equation.

First, multiply both sides of the equation by 14.

$\frac{4+p}{14} * 14 = 1 *14$

This gives you 4 + p = 14

Then, you can subtract 4 from both sides:

4 - 4 + p = 14 - 4

p = 10

The gas tank on the back of a tanker truck can be equated to a cylinder with a diameter of 8 feet and a length of 19 feet. A gal

Leokris [45]

Answer:

driver's tank: 30,427 lb
farmer's tank: 12,811 lb

Step-by-step explanation:

The formula for the volume of a cylinder is ...

V = πr^2·h . . . radius r, height h

The radius of the driver's tank is half its diameter, so is (8 ft)/2 = 4 ft. Then the volume of that tank is ...

V = π(4 ft)^2·(19 ft) = 304π ft^3

Each cubic foot of gasoline has a mass of ...

(1728 in^3/ft^3)(0.0262 lb/in^3) = 45.2736 lb/ft^3

Then the total mass in the driver's full tank is ...

(304π ft^3)(45.2736 lb/ft^3) ≈ 43,238.3 lb

__

The farmer's tank is a scaled-down version of the driver's tank. It's volume will be scaled by the cube of the linear scale factor, so will be (2/3)^3 = 8/27 of the volume of the driver's tank.

The farmer's tank will hold a mass of (43,238.3 lb)(8/27) ≈ 12,811 lb.

The amount remaining in the driver's tank is 43,238 -12,811 = 30,427 lb.

Which of the following shows the length of the third side, in inches, of the triangle below? (1 point)

GrogVix [38]

Answer:

2, sqrt of 7633

Step-by-step explanation:

for now, we'll leave the 3rd side as x

y using the Pythagorean theorem, we can conclude that (1) 48^2+x^2=73^2 or (2) 48^2+73^2=x^2.

1. If we conclude the x isn't the longest, the x would be 3025 which is the sqrt of 55, now is invalid because the 2 smallest sides can't be more than the longest side when they add up 55+48>73 so that is invalid

2. Then, it leaves us with only 1 choice left! concluding that the 3rd side is the longest. Which the answer is sqrt of 7633
