Answer:

It is not possible to form a polygon with side lengths of 6cm, 2cm, and 7cm. In order for a polygon to be possible, the sum of the interior angles must be less than 180 degrees. To form a polygon with 3 sides (triangle), the sum of the interior angles must be 180 degrees. But the sum of these side lengths does not add up to 180 degrees, therefore it's not possible to form a polygon with these side lengths.

On the windowsill is a plant that is 8 inches tall. It is growing 2 inches per week. A second plant, which is 3 inches tall, is on the coffee table. It is growing 4 inches per week. Eventually the two plants will be the same height. How tall will the plants be?

Answers

Answer:

Let's call the height of the first plant as x and the height of the second plant as y.

We know that the first plant is 8 inches tall and growing 2 inches per week, so we can write the equation:

x = 8 + 2t (where t is the time in weeks)

We know that the second plant is 3 inches tall and growing 4 inches per week, so we can write the equation:

y = 3 + 4t

We also know that the two plants will be the same height when they meet, so we can set the two equations equal to each other:

x = y

8 + 2t = 3 + 4t

5 = 2t

t = 2.5

So the plants will be the same height in 2.5 weeks. To find out how tall they will be, we can plug this value of t back into either equation:

x = 8 + 2(2.5) = 8 + 5 = 13 inches

y = 3 + 4(2.5) = 3 + 10 = 13 inches

So both plants will be 13 inches tall when they reach the same height.

Answers

2+3b is your answer! Hope it helps!


2 + 3b is the correct answer

Can someone pls explain to me

Answers

Answer:

272.5

Step-by-step explanation:

dotted line of the circle = 12 because this whole thing is a parallelogram + half a circle.  so diameter for the 1/2 circle is 12

so that means radius = 6, which is 1/2 of the diameter

circle area = π*r² = 36π

1/2 of it = 18π = 56.5

parallelogram area = base * height = 24 *9 =216

total  216+56.5

Doug builds a skateboard ramp.The base is 6 feet long and the height is 1.5 feet.What is the slope of the ramp?Explain

Answers

Answer: The slope of the ramp is 0.25

Step-by-step explanation: The slope of a ramp is a measure of how steep it is. It is typically expressed as a ratio of the height to the length, also known as the rise over the run. To calculate the slope of the ramp, you can divide the height by the length.

In this case, the ramp is 6 feet long and 1.5 feet high, so the slope is:

1.5 feet / 6 feet = 0.25

So the slope of the ramp is 0.25, which can also be written as a fraction 1/4 or 25%. This means that for every four feet of horizontal distance, the ramp rises by one foot.

Alternatively, you can think of this as the angle of the ramp, if the angle formed by the ramp is small it will have a small slope and if the angle formed is large, it will have a large slope.

In simpler terms, the slope represents how steep the ramp is. The higher the slope, the steeper the ramp will be. And the lower the slope, the gentler the ramp will be. In this case, since the slope is 0.25 it is a gentle ramp.

Answer:

0.25

.

What is the unit price of the tires?

Answers

Answer:

79.99

Step-by-step explanation:

You divided 319.96 by 4 which gives you 79.99

Answer:

$ 79.99

Step-by-step explanation:

4 tires = $319.96

1 tire =$b

cross multiplying,

4× b = 1 × 319.96

→ 4b = 319.96

→ b = 319.96 ÷ 4

therefore b = $79.99

3.9y + 3 - 2.9y=

anybody know?!

Answers

Answer:

= y + 3

Step-by-step explanation:

Group:

= 3.9y - 2.9y + 3

Add elements together:

= y + 3

3.9y + 3 - 2.9y

Arrange equation so that like terms are next to each other

3.9y - 2.9y + 3

Subtract.

1y + 3

Since 1y and 3 are not like terms, we cannot add them.

Therefore, 1y + 3 is the answer.
You can also write y +3.
