Answer:

7) 45.21

8) 114.5

9) 115.9

10) 105.6

Step-by-step explanation:

Volume of a cylinder is πr^2h

Substitute the values of 3.14 for π.

r = radius which is 1/2 of diameter

h = height

Round the answer to one place after the decimal (tenth place)

Can you solve the inequality 2(x-3) is less than or equal to 10 without using the distributive property? Explain.

STatiana [176]

Answer:

Yes, without using the distributive property, we get the value for the given expression 2(x - 3) ≤ 10 as x ≤ 8

Step-by-step explanation:

Here, the given expression is:

2(x - 3) ≤ 10

Yes, the given expression can be solved without using the DISTRIBUTIVE Property

Here, consider the given expression:

2(x - 3) ≤ 10

Now, divide the inequality by 2 on both sides, we get:

$\frac{2(x-3)}{2} \leq \frac{10}{2}\\\implies (x - 3) \leq 5$

Now adding (+3) on both the sides, we get:

(x - 3) ≤ 5 ⇒ (x - 3 + 3 ) ≤ 5 + 3

or, x ≤ 8

Hence, without using the distributive property, we get the value of x ≤ 8 for the given expression 2(x - 3) ≤ 10

What is the value of x in the following equation?<br> 4r +6<br> + 3 = -6<br> -6<br> -3

zhuklara [117]

Answer:

x = -6

Step-by-step explanation:

Solve for x:

(4 x + 6)/2 + 3 = -6

Hint: | Put the fractions in (4 x + 6)/2 + 3 over a common denominator.

Put each term in (4 x + 6)/2 + 3 over the common denominator 2: (4 x + 6)/2 + 3 = 6/2 + (4 x + 6)/2:

6/2 + (4 x + 6)/2 = -6

Hint: | Combine 6/2 + (4 x + 6)/2 into a single fraction.

6/2 + (4 x + 6)/2 = ((4 x + 6) + 6)/2:

(4 x + 6 + 6)/2 = -6

Hint: | Add the numbers in 4 x + 6 + 6 together.

Add like terms. 6 + 6 = 12:

(4 x + 12)/2 = -6

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of (4 x + 12)/2 = -6 by 2:

(2 (4 x + 12))/2 = -6×2

Hint: | Cancel common terms in the numerator and denominator of (2 (4 x + 12))/2.

(2 (4 x + 12))/2 = 2/2×(4 x + 12) = 4 x + 12:

4 x + 12 = -6×2

Hint: | Multiply 2 and -6 together.

2 (-6) = -12:

4 x + 12 = -12

Hint: | Isolate terms with x to the left hand side.

Subtract 12 from both sides:

4 x + (12 - 12) = -12 - 12

Hint: | Look for the difference of two identical terms.

12 - 12 = 0:

4 x = -12 - 12

Hint: | Evaluate -12 - 12.

-12 - 12 = -24:

4 x = -24

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 4 x = -24 by 4:

(4 x)/4 = (-24)/4

Hint: | Any nonzero number divided by itself is one.

4/4 = 1:

x = (-24)/4

Hint: | Reduce (-24)/4 to lowest terms. Start by finding the GCD of -24 and 4.

The gcd of -24 and 4 is 4, so (-24)/4 = (4 (-6))/(4×1) = 4/4×-6 = -6:

Answer: x = -6
