Answer 1

Answer:

Step-by-step explanation:

the answer is 3/2 because it goes 3 over 2 up

Answer 2

Answer:

2/3

Step-by-step explanation:

K=y/x

where y and x are two quantities that are directly proportional to each other

looking at the graph at x = 3 and y=2

therefore 2/3

also at x =6 and y = 4 (their proportional)

4/6 = 2/3

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.

Which inequality best represents that ice cream at −1°C is cooler than ice cream at 2°C?

Answers

Answer: The answer is -1°C < 2°C

Step-by-step explanation:

Inequalities are when something uses the greater than equal to or less than symbols. Also known as these <, =, >.

Because ice cream at -1°C is colder than ice cream at 2°C we would use the less than symbol (<).

It would be < (less than symbol)

A sweater is marked down 30% off the original price. The original price of the sweater was $42. What is the sale price of the sweater?

Answers

If the original price of the sweater is $42 and you get it for 30% off, it means that you are only paying 70% of the original price. So, the sale price would be . 70 X 42 = 29.40
The answer is $29.40

You take the original price and multiply it by .3(30%). Then you’ll take that answer, which is 12.6 and subtract it from 42

42x.3=12.6
42-12.6=$29.40

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.

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

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 value of x

Answers

Answer: 16 degrees

Step-by-step explanation:

Since m||n, then t is a transversal.

Therefore, you can see that x = 16 degrees

Answer:

16°

Step-by-step explanation:

Given that m and n are parallel, we know that the angles on this transversal are equal. Using the Alternate Exterior Angles Theorem we can see that x=16 because 16 degrees is the angle measurement of the alternate exterior angle.

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.
