Mathematics
1 answer:
Simora [160]3 years ago
8 0

Answer:

  no

Step-by-step explanation:

We want to compare the pot holder hole dimension to the pot dimension. The hole diameter is the overall pot holder diameter less the wall thickness on either side:

  hole diameter = (20 1/5) -2(1 2/7) = 20 -2(1) +1/5 -(2)(2/7)

  = 18 +(1/5 -4/7) = 18 +(7 -20)/35 = 18 -13/35

  = 17 22/35 . . . . cm

We want to compare this to 17 4/5. We can do that by using a common denominator for the fractions.

  17 4/5 = 17 + (4/5)(7/7) = 17 28/35 . . . . cm

The pot has a diameter of 17 28/35 cm; the pot holder has a hole diameter of 17 22/35 cm, so <em>the hole is smaller than the pot</em>.

The pot will not fit into the plant pot holder.

_____

You can use your calculator to find the free space around the pot by computing ...

  20 1/5 -2(1 2/7) -17 4/5 = free space = -6/35 . . . . cm

Negative space means the pot is larger than the hole.

Which of the following equations could describe a square pyramid? Select all that apply.<br> 3Vh =B
Oxana [17]

V= A(h/3) is the formula used for finding square pyramid.

Explanation:

In the above equation V stands for volume , A stands for base area, h stands for height. For finding the volume of square pyramid we need to follow certain steps, they are as follows:

First we need to measure all the side lengths present in the base. Secondly we need to calculate the base area , where the area of one sided square is a*a , then finally we need to multiply the base area with the height of the pyramid . To find the area of the square pyramid we use the formula-

A= a2+2a root over( a2/4+h2 )

Multiply Conjugates Using the Product of Conjugates Pattern
stealth61 [152]

Answer:

The product is the difference of squares is $$\left(5-3x\right)\left(5+3x\right)=25-9{{x}^2}$$

Step-by-step explanation:

Explanation

  • The given expression is (5-3 x)(5+3x).
  • We have to multiply the given expression.
  • Square the first term 5. Square the last term 3x.

$$\begin{aligned}&(5-3 x)(5+3 x)=(5)^{2}-(3 x)^{2} \\&(5-3 x)(5+3 x)=25-9 x^{2}\end{aligned}$$

How do I solve this?
LenKa [72]

Answer:

63

Step-by-step explanation:

Follow PEMDAS, as well as the left -> right rule.

Note that PEMDAS is the order of operations in which you should solve, and =

Parenthesis

Exponents (& roots)

Multiplication

Division

Addition

Subtraction.

First, look at the problem. The problem gives you:

42 ÷ 2 x (11 - 8)

Using PEMDAS, first, solve the parenthesis:

11 - 8 = 3

Next, use the left -> right rule to solve the rest.

42 ÷ 2 x 3

(42 ÷ 2) x 3

(21) x 3 = 63

63 is your answer.
