Johnny went to the park at 10:45am and left at 12:00pm. How long was he at the park?
[tex]\huge\mathcal{\fbox{\fbox\red{Hello}}}[/tex]
[tex]\large\underline{\mathbb{AnSwEr}:}[/tex]
10:45 am to 11:00 am : 15 minutes
11:00 am to 12:00 pm= 1 hour
Total Time= 1 hour 15 minutes.
so he was 1 hour 15 minutes at the park.
went at 10:45 AM
left at 12:PM
to find:the duration he was at the park.
solution:( to find the duration just find the difference of the time he left and went.
= 1 hour 15 mins.
therefore, he was at the park for 1 hour 15 mins.

Answer:
So, a.0, b.1/10, c.81, d.1/64
Step-by-step explanation:
Part A, anything raised to the power of zero is equal to zero. So suppose we have a constant, b, and we raise it to the power of zero, so b^0, it'll always be 0.
Part B, a negative power essentially means that you'll have to inverse the number. Once again, if we have a constant, b, and we raise it to the power of -1, it'll end up being 1/b. So b^-1 = 1/b.
Part C, its simply just multiplying 3 with itself four times.
Part D, as mentioned before, anything raised to a negative power means that you need to inverse the number. So 4^-3 is equal to 1/4^3, meaning that its just 1/64.

What are the solutions to the equation y = 4x2 +5x−6?
Answer:
Option D: x = -2; x = 3/4
Step-by-step explanation:
Hello!
We can factor this expression and then find the zeroes to find our solutions.
Factor:We have to factor by grouping. Multiply the 1st and last term, 4x² and -6 is -24x², and find two factors that equal to -24x² and add up to the second term, 5x. 8x and -3x work for this.
y = 4x² + 5x - 6y = 4x² + 8x - 3x - 6y = 4x(x + 2) - 3(x + 2)y = (4x - 3)(x + 2)Zero-Product PropertyNow, set the equation equal to zero.
0 = (4x - 3)(x + 2)Remember, if two numbers, a and b, multiply to 0, either a or b or both numbers must be zero. So now we set both factors to zero, hence the zero-product property.
4x - 3 = 04x = 3x = 3/4And the next one:
x + 2 = 0x = -2The solutions are x = -2, and x = 3/4, or Option D
Giselle made several apple and peach pies. She bought peaches for $4 per pound and apples for $2 per pound. If Giselle spent $60 to buy 24 pounds of fruit, how many pounds of peaches did she buy?
The number of pounds of peaches is 6 pounds and the number of pounds of apples is 18 pounds
Given:
cost of peaches per pound = $4
cost of apples per pound = $2
Total amount spent = $60
Total pounds bought = 24
let
x = number of peaches
y = number of apples
x + y = 24 (1)
4x + 2y = 60 (2)
multiply (1) by 2
2x + 2y = 48 (3)
4x + 2y = 60 (2)
subtract (3) from (2)
4x - 2x = 60 - 48
2x = 12
x = 12/2
x = 6
substitute x = 6 into (1)
x + y = 24 (1)
6 + y = 24
y = 24 - 6
y = 18
Therefore, the number of pounds of peaches is 6 pounds and the number of pounds of apples is 18 pounds

Simplify the expression. Write your answer as a power.
When multiplying two powers, if their bases are the same, then you simply add the exponents:
[tex]\frac{8^5*8^3*8^2}{8^8} =\frac{8^{5+3+2}}{8^8} =\frac{8^{10}}{8^8}[/tex]
When dividing two powers, if their bases are the same, you simply minus the exponents.
[tex]\frac{8^{10}}{8^8}=8^{10-8}=8^2[/tex]
Thus when the expression is simplified, the answer as a power is [tex]8^2[/tex]
Answer: 8^2

Two siblings, Miko and Cheko, receive some pocket money every month. This month, the ratio of Miko's pocket money to Cheko's pocket money is 8:12. Cheko's pocket money is $660. How much must Cheko give to Miko such that each of them have an equal amount of pocket money?
Cheko must give $110 to Miko so that each of them has an equal amount of pocket money, which is $550.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
The ratio of Miko's pocket money to Cheko's pocket money.
= 8:12
= 2:3
Now,
Let's represent Miko's pocket money as 2x and Cheko's pocket money as 3x.
We know that,
3x = $660
x = $220
Miko's pocket money.
= 2x
= 2($220)
= $440.
To make their pocket money equal,
Cheko needs to give half of the difference between their pocket money to Miko.
The difference between their pocket money.
= $220 (i.e., $660 - $440).
Half of that is $110.
Therefore,
Cheko must give $110 to Miko so that each of them has an equal amount of pocket money, which is $550.

Byron is conducting an experiment to determine whether a new medication is effective in reducing coughing. He finds 1,200 volunteers with coughing issues and divides them into two groups. The control group does not receive any medication; the treatment group receives the medication. The patients in the treatment group show reduced signs of coughing. What can Byron conclude from this experiment?
Answer:
Step-by-step explanation:
Given Byron's discovery of 1,200 volunteers with coughing problems.
He separates them into two categories:
1. There is no medication given to the control group.
2. The medication is given to the treatment group.
In addition, patients in the treatment group have fewer signs of coughing. As a result, Byron can conclude that the new medication works in the treatment group to reduce coughing.
The medicine given to the people, according to Byron, worked because the treatment group showed signs of less coughing.
Answer: Deduction is the effectiveness of the medication is positive since purpose for the trial was achieved. The cough symptoms responded to the medication while the control method used on the other group yielded no visible result. Medication was a better choice to the control method
Step-by-step explanation: Those who received the medication had their symptoms reduced while those who had other control measures showed no form of improvement.

Is this triangle acute, right, or obtuse?
acute
right
obtuse
Thus its an obtuse angle triangle.
=============================
Acute triangle means they measure less than 90°
Right triangle means a triangle with 90°
Obtuse triangle has one angle greater than 90°
Obtuse
Check one angle is streched like it's greater than 90°
Hence one angle is greater than 90 i.e obtuse.So
it's an obtuse triangle
