Kyle's yesterday's time was 108 seconds, or 1 minute and 48 seconds, faster than his normal time.
How much faster was Kyle's time yesterday than his normal time?To find the difference in time between Kyle's normal time and yesterday's time, we need to subtract his normal time from yesterday's time:
(21 minutes 38seconds)−(23 minutes 26 seconds)
(21 minutes 38 seconds)−(23 minutes 26 seconds)
We can first convert both times to seconds to make the subtraction easier:
=(21×60+38)seconds
−(23×60+26)seconds
=(21×60+38) seconds−(23×60+26) seconds
=(1298 seconds)−(1406 seconds)
=(1298 seconds)−(1406 seconds)
=−108 seconds
=−108 seconds
The result is negative because Kyle's yesterday's time is faster than his normal time. To find the positive difference, we can multiply by -1:
∣−108∣ =108seconds
∣−108∣= 108 seconds
Therefore, Kyle's yesterday's time was 108 seconds, or 1 minute and 48 seconds, faster than his normal time.

Determine the value of x in the given figure help
Answer:
x = 25
Step-by-step explanation:
The angles in a triangle must add up to 180 degrees, so:
180 - (53 + 27) = 100
100 ÷ 4 = 25
The size of a cell is typically found by capturing an image under a microscope then
using software to measure its diameter. Two cells are measured using this method:
Cell M: 7.65 x 10-3 centimeters
Cell N: 9.1 x 10-4 centimeters
What's the difference between the diameters of the two cells? Express your answer
using scientific notation.
Answer:
The difference is 6.74 * 10^-3 centimeters
Step-by-step explanation:
Firstly, we need to write the numbers as they would occur normally
we have this as;
7.65 * 10^-3 = 0.00765
9.1 * 10^-4 = 0.00091
So by subtracting, we have it that we subtract the value of the diameter of the cell N from that of the cell M since it is a bigger number
we have this as;
0.00765 - 0.00091 = 0.00674 and in scientific form is 6.74 * 10^-3 centimeters

A picture that measures 7 inches
by 7 inches is being framed.
The area of the picture with
frame is 81 square inches.
What is the width of the frame?
Answer:
The width of the frame is 2 inches
Step-by-step explanation:
The given dimensions of the picture = 7 inches by 7 inches
The area of the picture, A₁ = 7 in. × 7 in. = 49 in.²
The area of the given picture and the frame, A₂ = 81 square inches
Let 'w' represent the width of the frame and whereby the picture is a square, we have;
The area of the picture with the frame, A₂ = 81 in.² = (7 + w) × (7 + w)
A₂ = 81 = (7 + w) × (7 + w) = 49 + 14·w + w²
49 + 14·w + w² - 81 = 0
w² + 14·w - 32 = 0
(x + 16)·(x - 2) = 0
∴ x = -16 or x = 2
Given that 'x' is a natural number, we have;
The width of the frame, x = 2 inches.
de las 240 fichas que tiene un niño, 48 son rojas ¿cual es el porcentaje de las fichas rojas? debe ir desarrollo
these are not the right answers but does anyone know the right answers? please help
Answer:
Use this to get the area of any circle A = π r²
Step-by-step explanation:
I guess the upper circle has a radio of 10.5 m, then you multiply it by itself and you get that 10.5^2=110.25, and to that you add "π", and the area would be this "110.25π m."
And the other one is 7^2π=49π
A window washer cleaned 38 windows in 2 hours. At this rate, how many windows did he clean in 7 hours?
plz help
Answer:
133 windows in 7 hours
Step-by-step explanation:
38 divided by 2 and you get 19
19 x 7 = 133
Answer:
133 windows
Step-by-step explanation:
First, you would want to find how many windows he can clean in 1 hour.
You know that 38 windows = 2 hours.
To do this, divide both sides by 2 (to get 1 hour). You will get 19 windows = 1 hour.
Now to find 7 hours, multiply both sides of 19 windows = 1 hour by 7 (to get 7 hours). You will get 133 windows cleaned in 7 hours.

1. The points ( − 4, − 4), ( − 4, 4), (4, 4), and (4, − 4) form a square on a coordinate plane. How long is a side length of the square
Answer:
Length of one side is 8 units
Step-by-step explanation:
Given
The centre of this square is positioned at the origin as visible form the four co-ordinates
All the four co-ordinates are such that they are 4 units along the x-axis and 4 units along the y-axis.
Let us take the following two co-ordinates - (4,4),(4,−4). The X value for these two co-ordinate points is 4 and the Y values are such that one point has y = 4 and the other has y = -4 i.e 8 units in between.
Thus, length of one side is 8 units.
Find the unit rate in the following scenarios, and explain how you solved.

please help im very very desperate
Answer:
Exponential
Step-by-step explanation:
If it were quadratic, y-axis would fall and rise in points, so its not quadratic.
If it were linear, it would have a pattern with a rise/over formula, and it doesn't go in a pattern, so the only answer left is: Exponential.
Answer:
Exponential

What is linear equation???
Answer:
an equation between two variables that gives a straight line when plotted on a graph. In mathematics, a linear equation is an equation that may be put in the form {\displaystyle a_{1}x_{1}+\cdots +a_{n}x_{n}+b=0, } where x_{1}, \ldots, x_{n} are the variables, and {\displaystyle b, a_{1}, \ldots, a_{n}} are the coefficients, which are often real numbers.
If one side of a regular pentagon is represented by 3x + 1 , what is the perimeter of the pentagon?
Answer:
5(3x+1) or 15x+5
Step-by-step explanation:
A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value:
P = 5(3x +1)
Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5:
P = 15x + 5

A firm tested the durability of four different types of tires by having 4 Cadillacs each randomly equipped with one of the types of tires. In similar fashion, 4 Fords were used, each randomly equipped with one of the tire types. In a like manner, 4 Volkswagens were each randomly outfitted with one of the four tire brands. Then each of the twelve cars ran over a test track until the tires showed signs of serious wear. At that point the average mileage of the three cars using one type of tire was compared to the average mileage of the three cars using the second type of tires, and so on. This design is:
Answer:
Randomized block design
Step-by-step explanation:
In the scenario described above, the subjects which are the different car types are grouped into fixed units of 4 called blocks with each unit then assigned randomly to a particular treatment condition, which are the 4 different types of tire. In the end, the mean mileage for each block is taken and compared to that of the other blocks. This type of research design improves the reliability of the result obtained as it also eliminates the occurrence of systematic error in the course of our experiment.

The Sugar Company will choose from two companies to transport its sugar to market. The first company charges $5995 to rent trucks plus an additional fee of $175.50 for each ton of sugar. The second company charges $6500 to rent trucks plus an additional fee of $150.25 for each ton of sugar.
I think we're missing part of your question. The expression for cost for the first company will be:
5995 + 175.5x, where x is the number of tons of sugar
and the expression for the cost for the second company is:
6500 + 150.25x
