An elevator travels down from the top floor of a skyscraper. The graph below represents its height, in feet, over time in seconds. What does the slope of the line represent?
Answers
Answer:
So Y, which represents height, goes down depending on how far you are in time, which is X.
The slope of the graph represents the elevator's descent speed, calculated as 12 feet per second based on the points (1, 838) and (2, 826).
The Slope of the line in the graph represents the rate of change of height with respect to time, or the speed of the elevator's descent.
In this case, the slope can be calculated using the formula: slope = (change in height) / (change in time). We know that the elevator's height changes from 838 feet at 1 second to 826 feet at 2 seconds,
So, the change in height is : 838 - 826 = 12 feet, and the change in time is 2 - 1 = 1 second.
Therefore, the slope is 12 feet/second, this indicates that the elevator is descending at a speed of 12 feet per second.

Masha bought red, green, and yellow balloons for a party. She bought 40 red balloons. The number of green balloons Masha bought is 3/5 of the number of red balloons. The number of green balloons is also 2/3 of the number of yellow balloons. while being inflated, 1/20 of the red balloons, 1/12 of the green balloons, and 1/36 of the yellows balloons popped. The remaining balloons were used as decoration. What part of all the balloons Masha purchased to decorate the party?
Answers
Answer:
95 balloons
Step-by-step explanation:
red = 40
green- 40x(3/5) = 24
yellow- 24÷(2/3) =36
36× (1/36) = 1. 1 yellow balloon popped
24× (1×12) = 2. 2 green balloons popped
40×(1/20) =2. 2 red balloons popped
40+24+36= 100
2+2+1=5
100-5 = 95 balloons left for decorations

In the given figure, no pair of opposite sides are parallel.
There are no parallel side in the given figure.
Given is a figure we need to determine if there are any parallel side or not,
So, the parallel sides are defined as =
When two or more sides of a polygon are described as parallel, it means that they never cross over and are always equally spaced apart.
In other words, these sides would never intersect or cross each other if you extended them endlessly.
Shapes like squares, parallelograms, rectangles, and trapezoids are frequently linked to the idea of parallel sides.
The opposing sides of these polygons are parallel to one another. For instance, just one pair of opposite sides in a trapezoid is parallel but both sets of opposite sides are parallel in a rectangle.
So according to the definition of parallel lines there are no parallel sides in the figure.

you would first solve it like a normal equation and ignore the negative;
0.5 * 4 is 2

and then you would add the negative sign- because there is only one side with a negative sign, it is negative
if the equation had both sides had a negative, it would be positive

1.21 rounded to the nearest whole number
Answers
1 is the whole number and to round you look one place over, in this case the number one over to the left if 2. If the number to the left is 5 or more you “raise the score” making the number your rounded go up one. If the number is 4 or less, you “let it rest” meaning the number stays the same. Once you round, you drop every number behind the number you used to round. So instead or 1.21 it’s 1.2

C - the value of point F is the opposite of point A
As point A is -3 whereas point F is +3
The formula for converting from Celsius to Fahrenheit is F=9/5C+32. The Fahrenheit temperature of a certain city has never exceeded 86 degrees. How would you describe this using Celsius temperature?
Answers
Answer:
The temperature in Celsius in this city has never exceeded 30 °C
Step-by-step explanation:
Just substitute F by the temperature in Fahrenheit and solve the equation:
86 = 9C/5+32 Multiply both sides by 5
5×86 = 9C +32×5
430 = 9C + 160 Subtract 160 in both sides
270 = 9C Divide both sides by 9
30 = C

Make a system of equations.
Let s be the number of skips interviews and w be the number of woodys interviews.
s=w-8
s+w=20
Then just use algebra to rearrange and find each persons interviews.
For this one we can rearrange the second equation to get s=20-w.
Since we have two solutions for s we can set them equal.
w-8=20-w
2w-8=20
2w=28
w=14
Now that we have the number of woodys interviews substitute it into the first equation to get skips interviews.
s=w-8
s=14-8
s=6
So skip had 6 interviews and woody had 14 interviews.

y-x=7
x+y=33
Then just use algebra to rearrange and find each amount of items.
Start by solving with substitution. (Elimination could work too im just going to use substitution.)
y-x=7
y=7+x
Substitute into the second equation
x+(7+x)=33
2x+7=33
2x=26
x=13
Now plug this x value back into the first equation
y-13=7
y=20
The number of items on one list is 13 and the number of items on the second list is 20.

Trey is taking his friends out to dinner to celebrate graduation. It will cost him $72 to reserve a table, and another $5 per guest. How many people can he invite if he can only spend up to $130?
Answers
Answer:
11 people
Step-by-step explanation:
first, youd subtract the table reservation price from the max price.
130 - 72 = 58
then, since each person costs $5, you find the highest multiple of 5.
in this case, its 55, which has 11 groups of 5 in it.
to make sure:
you can then subtract 55 from 58 to make sure there isnt any extra 5's.
58 - 55 = 3.
