Which property of real numbers is shown below? 3 + ((-5) + 6) = (3 + (-5)) + 6

2 answers:

7 0

3 + ((-5) + 6) = (3 + (-5)) + 6

it's associative property because the expression is staying the same, but the parentheses move

<span>3 + ((-5) + 6) = (3 + (-5)) + 6

It's </span>associative property of addition

The associative property of addition states that you can add regardless of how the numbers are grouped, result will state the same.

What is the volume of a right circular cylinder with a base radius of 6 feet and a height of 10 feet? 900 cubic meters 120 cubic

kvv77 [185]

Step-by-step explanation:

the volume of a cylinder is

base area × height = pi×r² × height

with r being the radius.

so, we get

pi×6² × 10 = pi×36 + 10 = 360pi =

= 1,130.973355... ft³

now we need to look at the conversion rate between feet and meters :

1 ft = 0.3048 m

1 ft² = 0.3048² m² = 0.09290304 m²

1 f³ = 0.3048³ m³ = 0.028316847... m³

1,130.973355... ft³ = 1,130.973355... × 0.028316847... =

= 32.025599... m³

so, something is not right with your answer options. it looks like you put maybe the answer options of a different question in here.

but none of them get even close to the actual solution of the given question.

Given: △PTC

Natalka [10]

Given the the two angles find the missing angle of P which is 30 degrees.

Since angle P and C are identical their sides are congruent.

The hypotenuse, the largest side is PC because it corresponds to angle T

Using Pythagorean Theorem
a^2 + b^2 = c^2

(PT)^2 + (CT)^2 = (PC)^2
Given that PT is 4 and knowing PT and CT are congruent we can rewrite this
(4)^2 + (4)^2 = (PC)^2
PC = rad(32)

Someone fact check plz

Use two unit multipliers to convert 628 kilometers to centimeters

irina [24]

Using two unit multiplier 628 km is equal to 62800000 cm

<u>Solution:</u>

628 kilometer to centimeter

We will go from kilometers to meters to centimeters.

Start by putting 628 km over 1:

$\frac{628 km}{1}$

We want to get rid of km and bring in m.

We know that 1000 m = 1 km.

Since km is in the numerator, we will make the first unit multiplier by putting 1 km in the denominator and 1000 m in the numerator, so the km will cancel. So we multiply by the unit multiplier,

$\frac{628 km}{1} \times \frac{1000m}{1km}$

Now the km's will cancel:

$\frac{628}{1} \times \frac{1000m}{1}$

Now we want to get rid of m and bring in cm.

We know that 100 cm = 1 m.

Since meter is in the numerator, we will make the first unit multiplier by putting 1 meter in the denominator and 100 cm in the numerator, so the meter's will cancel. So we multiply by the unit multiplier

$\frac{100cm}{1m}$

$\frac{628}{1} \times \frac{1000m}{1} \times \frac{100cm}{1m}$

We cancel the m's and we end up with:

$628 \times 1000 \times 100 cm$

= 62800000 cm

Thus 628 km is equal to 62800000 cm

In 2021 Florida's minimum wage will be $10 per hour. In 2026 the minimum wage will increase to $15 per hour. What is the percent

nevsk [136]

Answer:

50% value change.

Step-by-step explanation:

A 100% increase from 10 would be 20. It's the equivalent of doing 10 times 2. We need 15 though which is half the distance in value to 10 than 20 is. Half of 100% is 50%.

Therefore, $15 is a 50% percent change from $10.
