Answer:

The units are always squared.

The area can be found when given the diameter by first finding the radius.

Circumference can be used to find area.

Step-by-step explanation:

1) The diameter is NOT used in the formula. The formula is

Area = pi * radius * radius

2) The units are always squared. Units for area are always squared.

3) The area can be found when given the diameter by first finding the radius.

Diameter/2 = radius, which is the only missing part we need to find the area.

4) The area is NOT the distance around the circle. That is the circumference. Area is contained within the circle.

5) Circumference can be used to find area.

Circumference/pi = diameter, and with the diameter, we can find the area as explained in 3

Decide whether the statement is true or false. If it is​ false, explain why. The union of the solution sets of 4xplus5equals13​,
postnew [5]

The given statement is false because it isn't an empty set!

<u>Step-by-step explanation:</u>

We have following sets of inequalities:

4x+5=13\\4x+5>13\\4x+5

From 4x+5=13 we get ,

4x = 8 \\x=2

Therefore solution set is x=2.

Now, for 4x+5>13 we get ,  

4x+5>13 \\4x>8\\x>2

Therefore solution set is x>2.

For 4x+5 we get ,

4x+5

Therefore solution set is x<2.

Now, the union of x=2, x<2 & x>2 is  -∞<x<∞. i.e. all possible values of x. And so above statement is false because it isn't an empty set!

You go to the store and pick out 3 apples for $0.60 each, 2 bananas for $0.50 each, and 1 quart of yogurt for $4.50. At checkout
Stella [2.4K]

Answer:

$6.21

Step-by-step explanation:

1 apple = $0.60

3 apples = $1.80 (Multiply 0.60 by 3)

2 bananas = $1.00 (Multiply 0.50 by 2)

1 quart of yoghurt = $4.50

Add the prices up first:

1.80 + 1.00 + 4.50 = $7.30

7.30 off 15% = $6.21

Plug in the values for x and y to check.

-6>8-10
-6>-2

Final answer: False
This is because -6<-2. Remember that for negative numbers, the number with the greater absolute value is less.
