Answer:

i need to know more

Answer:

No

Step-by-step explanation:

Two positive integers can never make negative integers because they are all greater than 0. For example, numbers above 10 like 11 and 13 can never add up to 10. It is the same with negative numbers

Answer:

C

Step-by-step explanation:

It isn't B because the point does not start at 600 and it is not A because it shows the entire decrease of the mass in one millennium. The correct answer is c.

Step-by-step explanation:

1.) 5x-4y=20

y=5/4x-5

5x/4-5=0

x=4

2.) 3x+3y=15

y=-x+5

x+5=0

-x=-5

=x=5

3.) y=3/4x-2

3/4x-2=0

x=0

3x4x/4 -2 x4x-0x4x

3-2x4x=0x4x

3-8x=0

8x=-3

=x=3/8

4.) y=3/2x+3

3/2x+3=0

x=0x

3x2x/2+3x2x=0x2x

3+3x2x=0x2x

3+6x=0

6x=-3

x=_3/6

=x=-1/2

Step-by-step explanation:

To find the area of the fountain, we need to add up the areas of the two semicircles and the quarter circle: Area = πr^2/2 + πr^2/2 + πr^2/4 Area = (5π^2/2 + 5π^2/2 + π^2/4)/π^2 Area = 21/4 Using a calculator, we can approximate this as about 5.25 square feet.

Answer:

0 (\(\sqrt{0}\) = 0)

Step-by-step explanation:

If 0^2 = 0 because 0 x 0 = 0, then the reverse function (square root) would result in 0.

Answer:
W= 18
L= 5

Step-by-step explanation:

let width = x cm

so length = x - 13 cm

According to question ,

Area = length × breadth

90 = x( x-13)

90= x^2 - 13 x

x^2 -13x - 90 =0

x^2 -18x + 5x -90 =0

x(x-18) + 5(x- 18)= 0

(x-18)(x+5)= 0

take x - 18 = 0

so x = 18

take x+5 = 0

that gives x= -5 ( not possible)

so width = 18 cm

and length = 18- 13 = 5 cm.

Answer:

false

Step-by-step explanation:

explanation:

Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.

Answer:  -7

Step-by-step explanation: To find the mean, here is the equation =

Divide the sum of all values in a data set ÷ the number of values = mean (average)

Step 1 :

So we do =

17 + -25 + 3 + -29 + -15 + 7 = -42

So the sum of the integers is -42

Step 2 :

We divide the sum by the number of values.

17, -25, 3, -29, -15, 7

1      2   3     4      5   6

So there are 6 values.

We do =

-42 ÷ 6 = -7

So the mean (average) of these integers is -7

Step-by-step explanation:

Answer:

60.8π square inches.

Step-by-step explanation:

The label is a rectangle that will be wrapped around a cylinder. So, the area of the label can be found by multiplying the height of the rectangle by the circumference of the cylinder. The circumference of the cylinder can be found by multiplying the diameter by π. Since the two circles in the figure represent the top and bottom faces of the cylinder, the diameter is 2 × 4 = 8 inches. Therefore, the circumference of the cylinder is 8π inches. Thus, the area of the label is:

7.6 × 8π = 60.8π square inches

Therefore, the label is 60.8π square inches.

Answer:

60.8π square inches

Step-by-step explanation:

Chain of thought reasoning: 1. The label is represented by the rectangle in the figure.

2. The area of a rectangle is equal to the width multiplied by the height or A = w x h.

3. The width of the rectangle is equal to the circumference of the circles.

4. The circumference of a circle is equal to 2πr, where r is the radius of the circle.

5. Therefore, the width of the rectangle is equal to 2π x 4 = 8π inches.

6. The height of the rectangle is 7.6 inches.

7. Therefore, the area of the rectangle is equal to 8π x 7.6 = 60.8π square inches.
