If set D is not the empty set but is a subset of set E, then which of the following is true? D ∩ E = D
D ∩ E = E
D ∩ E = Ø

Answers

Answer 1

Answer: Concept:
If every element of a set D is an element of set E, then D is the subset of E.
e.g
D={1,2,3}, E={1,2,3,4}
As all the elements of D are in E, so D is the subset of E.
Now the intersection of two sets D and E is the set of all elements which belong to both D and E.
As, in our example the set D={1,2,3} is the intersection of set D and set E.

From the above discussion, it is proved that If set D is not the empty set but is a subset of set E then
D ∩ E = D is the true answer.

if the radius of a circle is 3.5 inches its diameter is ____ inches and its approximate area is____ square inches

Answers

Answer:

Diameter = 7 inches

Area of circle is 38.46 inches²

Step-by-step explanation:

Given :The radius of a circle is 3.5 inches.

We have to find its diameter and area.

Since diameter is twice of radius.

So radius = 3.5 inches

Diameter = 2× 3.5 inches = 7 inches

Area of circle = $\pi r^2$

Substitute, r = 3.5

Area of circle = $\pi (3.5)^2$

Simplify , we have,

Area of circle = $\pi 12.25$

Using π = 3.14

We have,

Area of circle = $38.465$

Thus, Area of circle is 38.46 inches²

The diameter is 7 inches and the area is 38.465. I got the answer by taking the area of a circle's formula which is

pi r ^2

Which pair of measurements is not equivalent?160 oz., 10 lb.
5 lb., 80 oz.
14,000 lb., 7 tons
4 tons, 6,000 lb.

Answers

If you would like to know which pair of measurements is not equivalent, you can calculate this using the following steps:

1 lb = 16 oz
1 ton = 2,000 lb

10 lb = 10 * 16 oz = 160 oz
5 lb = 5 * 16 oz = 80 oz
7 tons = 7 * 2,000 lb = 14,000 lb
4 tons = 4 * 2,000 lb = 8,000 lb

Not equivalent: 4 tons, 6,000 lb.

|h-8|=|h+10| What is h

Answers

Your answer is h= -1

Final answer:

The value of h that satisfies the equation |h-8|=|h+10| is -1.

Explanation:

To solve the equation |h - 8| = |h + 10|, we need to consider two cases based on the absolute values.

First, when h - 8 is positive, we can rewrite the equation as h - 8 = h + 10. Simplifying this equation, we find that -18 = 0, which is not true.
Second, when h - 8 is negative, we rewrite the equation as -(h - 8) = h + 10.
Simplifying this equation, we get -h + 8 = h + 10.
Combining like terms, we have 2h = -2.
Dividing both sides by 2, we find that h = -1.
