Answer:
-55.32
Step-by-step explanation:
55.32 + (-55.32) = 0I hope this helps!
Answer:
Well the number would have to be a negative number, because, no positive number can cause a smaller number adding a positive number will always cause a larger number.
So the answer is: $55.32+(-$55.32)
Adding the -55.32 causes it to even out meaning that u basically just added the debt of 55.32. This debt is causing an decrease in the amount of money she has. So really you are subtracting money

In a relay race, each runner completes the circuit 9 seconds faster than the previous one. If the first athlete runs his lap in 4 minutes 37 seconds, how many minutes does it take in total for the team of 8 competitors to finish the race? Give your answer correct to the nearest minute. [Answer format: integer, no units]
Answer:
31 minutes
Step-by-step explanation:
Here, we have 8 competitors with the previous runner outrunning the present by 9 seconds
1st runner time = 4 minutes 37 seconds
2nd runner time = 4 minutes 37 seconds - 9 seconds = 4 minutes 28 seconds
3rd runner time = 4 minutes 28 seconds - 9 seconds = 4 minutes 19 seconds
4th runner time = 4 minutes 19 seconds - 9 seconds = 4 minutes 10 seconds
5th runner time = 4 minutes 10 seconds - 9 seconds = 4 minutes 1 second
6th runner time s= 4 minutes 1 second - 9 seconds = 3 minutes 52 seconds
7th runner time = 3 minutes 52 seconds - 9 seconds = 3 minutes 43 seconds
8th runner time = 3 minutes 43 seconds - 9 seconds = 3 minutes 34 seconds
The total time is the addition of all the times
For clarity sake, we shall be adding all the minutes together and all the seconds together;
That will be ;
(4 * 6) + 3 minutes + ( 34 + 43 + 52 + 1 + 10 + 19 + 28 + 37)
= 27 minutes + 224 seconds
We need to convert 224 seconds to minutes
Since 60 seconds make one minute; we have
224 - 60(3) = 3 minutes and 44 seconds
Let’s add this to the minutes we had before
That would be;
27 minutes + 3 minutes + 44 seconds
= 30 minutes 44 seconds
since 44 seconds is greater than 1/2 minute (30 seconds), we can approximate it to 1 minute
So the total time is 30 minutes + 1 minute = 31 minutes

All 25 students in our class were surveyed about what their favorite food is. 11 students chose pizza. What
percentage of the class chose pizza?
Easy
[tex] \frac{11}{25} \times 100 = \frac{11}{25} \times 25 \times 4 \\ [/tex]
[tex] = 11 \times 4 = 44 \: \: percent[/tex]
So %44 of your class students chose pizza.
The percentage of the class chose pizza = 44%
What is percentage?"It is a number or ratio that can be expressed as a fraction of 100."
For given example,
Total number of students = 25
the number of students who chose pizza as their favorite food = 11
So, the percentage of the class chose pizza would be,
⇒ (11/25) × 100 = 44%

Sam counted his heartbeats while resting. His heart beat 220 times in 4 minutes. Sam's heart beat at the same rate for the 4 minutes.
The equation for the number of beats per minute is 55 beats per minute
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of beats be = A
Now , the value of A = 220 beats
The total time required for Sam to have 220 beats = 4 minutes
So , the number of beats of Sam in 1 minutes is calculated by
The equation will be
The number of beats of Sam in 1 minutes is = total number of beats / total time required for Sam to have 220 beats
The number of beats of Sam in 1 minute is = 220 / 4
The number of beats of Sam in 1 minute is = 55 beats per minute
Therefore , Sam would have 55 beats every minute or 55 beats per minute
And for the period of 4 minutes , Sam would have
Number of beats for 4 minutes = number of beats of Sam in 1 minute x 4
Number of beats for 4 minutes = 55 x 4
Number of beats for 4 minutes = 220 beats in 4 minutes
Hence , The equation for the number of beats per minute is 55 beats per minute

Two stores are having a sale on the

30% off the regular price of $82.40.
The other store is offering 20% off
the regular price of $63.60.
What is the difference between the
sales prices of the two stores?
DONT ANSWER IF U DONT KNOW.!
Answer:
6.8
Step-by-step explanation:
30% of 82.40 = 24.72
20% of 63.60 = 12.72
--------------------------------
82.40 - 24.72 = 57.68
63.60 - 12.72 = 50.88
57.68 - 50.88 = 6.8
Answer:
6.8
Step-by-step explanation:
Wendy was traveling from Baltimore, MD to Cleveland, OH. For the first 2 3/4 hours of her trip, she drove an estimated 63 mph. For the second portion of her trip, which took her 3 1/2 hours, she drove at an estimated rate of 57 mph. Write an expression to model her distance and calculate how far she drove. You may use the distance formula d=r*t (distance = rate * time).
Answer: D = r*t + r*t 372 3/4 = (63 * 2 3/4) + (57 * 3 1/2)
OR
D1 + D2 = Total 173 1/4 + 199 1/2 = 372 3/4
D1 = r1 *t1 63 * 2 3/4 = 173 1/4
D2 = r2 * t2 57 * 3 1/2 = 199 1/2
Step-by-step explanation:
The trip is in two segments, so calculate the distance driven in each portion, then add the two distances together to get the total.
Another way to write the expression would be D = r*t + r*t
The total distance that Wendy drove to Cleveland will be 372.75 miles.
For the first 2 3/4 hours of her trip, she drove an estimated 63 mph. Then, the distance traveled will be:
= 63 × 2 3/4
= 173.25 miles.
For the second portion of her trip, which took her 3 1/2 hours, she drove at an estimated rate of 57 mph, the distance will be:
= 57 × 3 1/2
= 199.5 miles
The total distance traveled will then be:
= 173.25 miles + 199.5 miles
= 372.75 miles.

The three angles of a triangle are in the ratio 5:4:1. Find all the angles of the triangle.
Answer:
Step-by-step explanation:
let the first angle be 5x
second be 4x
and third be 1x
as we know that by adding all the sides of triangle we get 180°
therefore ,
5x+4x+1x=180°
10x=180°
hence ,
x=18°
first angle - 18*5 = 90°
second angle - 18*4=72°
third angle - 18°
HOPE THIS HELPS YOU !!!
Answer:
18°, 72°, 90°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the parts of the ratio, 5 + 4 + 1 = 10 parts
divide to find the value of one part of the ratio
180° ÷ 10 = 18° ← value of 1 part of the ratio , thus
5 parts = 5 × 18° = 90°
4 parts = 4 × 18° = 72°
Thus the angles of the triangle are 18°, 72° and 90°

2(5x+1)−2x=2−2(3x+1)
Answer:
[tex]x = -\frac{1}{7}[/tex]
Step-by-step explanation:
2(5x + 1) - 2x = 2 - 2(3x + 1)
Use the distributive property
10x + 2 - 2x = 2 - 6x -2
Combine like terms
8x + 2 = -6x
Subtract 2 from both sides
8x = -6x - 2
Add 6x to both sides
14x = -2
Divide both sides by 14
x = -2/14 = -1/7
