Answer:

1005 cm³ will be the volume of the cylinder cardboard tube.

Step-by-step explanation:

Diameter of a cylinder cardboard tube = 8 cm

Therefore radius = 4 cm.

Height of the cylinder cardboard tube = 20 cm.

Now we have to calculate the volume of the tube

As we know the formula of the volume of cylinder is

V = πr²h

V = π (4)²(20) = 320π cm³

Now we put the value of π as 3.14

Volume = 3.14×320 = 1004.80 ≈ 1005 cm³

Therefore Volume of the cylinder cardboard used to package a gift will be = 1005 cm³

How do you solve 1-5+1×(4×4-31)×8
Alja [10]
Hey there!

In order to solve this, remember PEMDAS. First, start with solving whatever is in parentheses. Then, move on to exponents. Then, complete the multiplication and division. Lastly, add or subtract anything remaining. Omit any steps that aren't present. 

Parentheses: 

<span>1 – 5 + 1 × (4 × 4 – 31) × 8
</span>1 – 5 + 1 × (–15) × 8

Multiplication/Division (Left to Right):

1 – 5 + (–15) × 8
1 – 5 + (–120)
1 – 5 – 120

Addition/Subtraction (Left to Right):

–4 – 120
–124

Your answer is –124. 

Hope this helped you out! :-)

Factor the polynomial by grouping : x^3+5x^2-6x-30
andrew-mc [135]

The idea is to pair up the terms, factor each sub-group, and then pull out the overall GCF to fully factor.

x^3+5x^2-6x-30

(x^3+5x^2)+(-6x-30)

x^2(x+5)+(-6x-30)

x^2(x+5)-6(x+5)

(x^2-6)(x+5)

-------------

Answer: (x^2-6)(x+5)

A line includes the points (-3, 8)and (-1, 2). What is its equation in slope- intercept form
Natasha_Volkova [10]
Solve for slope first:
m = \frac{y2 - y1}{x2 - x1}

m = \frac{2-8}{-1-(-3)} = -3

then solve for b in y = mx + b

8 = -3(-3) + b
b = -1

y = -3x - 1

For A = {a,b}, determine A x P(A).
alex41 [277]

Answer:

Since A={a,b}, then P(A)=\{\emptyset, \{a,b\}, \{a\}, \{b\}\}. Remember that the Cartesian Product of two sets A, B is defined by

A\times B=\{(x,y): x\in A \text{ and } y\in B\}. Then

A\times P(A)=\{(a,\emptyset),(a,\{a,b\}),(a,\{a\}), (a,\{b\}), (b,\emptyset),(b,\{a,b\}),(b,\{a\}), (b,\{b\})\}
