Draw a right triangle with side lengths of 3, 4, and 5 units.
and answer the problem please :')
Answer:
Image below
Step-by-step explanation:
Given: Side lengths of a right triangle 3,4 and 5 units.
To draw: A right triangle with the given side length.
Solution:
We know, in a right angle triangle hypotenuse is the longest side and satisfying Pythagoras theorem.
From the given side length,
Hypotenuse = 5 unit
We can take any of the base and perpendicular.
Let, Base = 3 unit
Perpendicular = 4 unit.
It a right-angle triangle with a hypotenuse 5 unit.
Now we draw a right angle triangle taking in the first 3 base and 4 perpendicular and second 3 perpendicular and 4 bases.

Children get a 15% discount on tickets to an amusement park. Jun had a coupon for 5% off any two tickets. He used the coupon for himself and his 4-year-old son, Jack. If regular admission for a ticket was $60, what did Jun pay for the two tickets?
The amount that Jun paid for the two tickets given the discount rate and the coupon rates is $105.45.
How much was paid for the two tickets?Discounts and coupons reduce the price of an item.
Cost of the child's ticket after the discount = (100 - 15%) x 60 = $51
Cost of both tickets after the coupon = (100 - 5) x (51 + 60) = $105.45

Answer:
First question: 2/3
Second question: -2
Step-by-step explanation:
2x - 3y = 6
Subtract 2x from both sides
-3y = -2x + 6
Multiply by -1
3y = 2x - 6
divide by 3
y = 2/3x -2
The equation basically asks for slope, so 2/3
x + 1/2y = 5
Subtract x
1/2y = -x + 5
multiply by 2
y = -2x + 10
it is -2

I'm solving systems and I don't understand how to do it pls helpp
Answer:
Use the process of elimination. I'll only do one example since you have 4.
Step-by-step explanation:
Let's do the first question.
2x-3y=-11
2x+y=9
Our goal here is to be left with one variable to solve, this way we can use the answer for that variable to find the other. A.K.A only find X to plug into the equation to find Y. To do this, we'll use the process of elimination, in which we need to cancel out a variable.
X seems the easiest here. To cancel 2 (in the top equation), you need to have a -2. And that -2 needs to be the x coefficient in the 2nd equation, in order for us to "cancel" it out. To get -2, you multiply 2 by -1.
-1(2x+y)= -1(9)
Note that whatever you do to one side, you need to do it to both sides! Hence, why I also multiplied 9 by -1. You should now be left with:
-2x -y = -9
Now, we cancel out the positive 2 and -2 from both equations by adding the two equations.
2x-3y= 11
+
-2x-y=-9
X cancels out, so we're left with -4y=-20. Solve for Y, which is 5.
-4y=-20
y=5
Now that you have the Y value, plug it into any of the two equations to find your X value.
2x-3y=11
2x-3(5)=11
2x-15=11
2x=26
x=13
And voilah! Our Y value is 5, and our X value is 13.
It's pretty simple once you understand what's going on. All that we did was to cancel out one variable (either X or Y) in the two equations so that we're left with only one variable to solve. If we cancel out X, we only need to solve for Y. You do this by manipulating one of the two equations (doesn't matter which one). Once you find either X or Y, all you need to is to plug it into one of the original equations. Then, you'll have both X and Y.
And that my friend, is the process of elimination. Good luck!
A girl's feet are negative 2 over 4 yards from the surface of a pool. A boy's feet are negative 3 over 4 yards from the surface of the pool. Determine whose feet are closer to the surface.
The girl's feet are closer to the surface of the pool because negative 2 over 4 > negative 3 over 4.
The boy's feet are closer to the surface of the pool because negative 2 over 4 > negative 3 over 4.
The girl's feet are closer to the surface of the pool because negative 2 over 4 < negative 3 over 4.
The boy's feet are closer to the surface of the pool because negative 2 over 4 < negative 3 over 4.

Write your answer as a whole number or decimal.
Measurements of atoms, such as amounts, distances, and weights, are often very large or very small when compared to measurements of things you can see or touch. Scientific notation represents numbers as a power of 10. This makes very large or small numbers easier to use and understand. Approximately 7,500,000,000,000 carbon atoms fit across the period that you make with your pencil. Express this number in scientific notation. (PLEASE ANSWER FAST I'LL GIVE BRAINLIEST ALSO PLEASE DO ALL THIS IS WORTH 30 POINTS)
Step 1 Rewrite the number with a decimal after the first nonzero digit.7.500000000000
Step 2 Find the number of places and the direction you moved the decimal. If a number does not show a decimal, the decimal is at the right end of the number.You moved the decimal 12 places to the left.
Step 3 Drop the zeros, and write the number of places you moved the decimal as a power of 10. If you moved the decimal to the right, the power is negative. If you moved the decimal to the left, the power is positive.7.5 × 10 12
Step 4 Reverse the process to change scientific notation back to a whole number. A positive power of 10 moves the decimal to the right. A negative power of 10 moves the decimal to the left.
(Answer 1, 2, 3, 4 and 5 )

An art teacher makes a batch of purple paint by mixing 3/4 cup red paint with 3/4 cup of blue paint. If she mikes 13 batches, how many cups of purple paint will she have?
Answer:
She will have 19 ¹/₂ batches of purple paint
Step-by-step explanation:
r + b = 1 bp
³/₄ r + ³/₄ b = 1 bp
(³/₄ + ³/₄) * 13 = x bp
⁶/₄ = 1 ¹/₂
1 ¹/₂ * 13 = 13 ¹³/₂ = 19 ¹/₂ batches
VARIABLE KEY:
r = red
b = blue
bp = batches of purple
x = total number of bp

Erik is performing a marble experiment in math class. His teacher places an equal number of black, red, and white marbles in a bag. Then, Erik randomly takes out a marble, records the result, and puts the marble back in the bag. Each of the first four times Erik takes out a marble, he gets a black marble.
A. What is the theoretical probability of Erik picking a black marble next time? Based on Erik's results, what is the experimental probability of Erik picking a black marble next time?
B. Explain the difference between the two probabilities you found in part A.
C. What is the theoretical probability and likelihood of getting four black marbles in a row?
Answer:
Every one of us would have encountered multiple situations in life where we had to take a chance or risk. Depending on the situation, it can be predicted up to a certain extent if a particular event is going to take place or not. This chance of occurrence of a particular event is what we study in probability. In our everyday life, we are more accustomed to the word ‘chance’ as compared to the word ‘probability’. Since Mathematics is all about quantifying things, the theory of probability basically quantifies these chances of occurrence or non-occurrence of certain events. In this article, we are going to discuss what is probability and its two different types of approaches with examples.
