Answer:
-1 ¹/₉
Step-by-step explanation:
Firstly, let:
x = -1.111...
This means:
10x = -11.111...
Then:
10x - x = -11.111... - (-1.111...)
9x = -11.111... + 1.111...
9x = -10
x = -¹⁰/₉
x = -(⁹/₉ + ¹/₉)
x = -1 ¹/₉

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

Answer: 8/35 square yards
Step-by-step explanation:
The formula to find an area of a rectangle is L * W (length * width). Here your length would be 4/7 yards, and your width would be 2/5 yards, so plugging it into the formula would be 4/7 * 2/5 = 8/35 square yards.

what is the value of x
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.

Answer: 52.2
Step-by-step explanation:
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?
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.

t's possible that the circle's diameter and circumference are the same as 7.2 inches and 28 inches. To answer the question, I'm going to use the formula C. Equals pi times D. It's Mhm. It's not possible for a circle with a diameter of 7.2 in to be the same as a circle with a 22.62 in pi. You end up with a smaller circumference when you plug 7.2 into the formula for circumference.
Can someone pls explain to me
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
What is the value of x and y?
Answer: y=41 and x=41
Answer:
x=41 y=41
Step-by-step explanation:
y is a mirror of the other side which is 41 degrees. So y=41. m and n are parallel so x is also equal to 41.

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
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

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.
