Answers
Answer:
2 balloons = h/4 15 balloons = a/30 10 balloons = c/20 21 balloons = i/42 3 balloons = f/6 4 balloons = k/8 5 balloons = j/10
Step-by-step explanation:
Every time you have a number of balloons, since each costs 2 dollars, you would double the number of balloons to get the price of all of the balloons! Hope this helps! Have a great day!

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Jane is saving money to buy a game. The game costs $20, and so far she has saved four-fifths of this cost. How much money has Jane saved?
Answers
Answer:
she has 16$ saved
Step-by-step explanation:
20 divided 5 = 4
4 fifths of 20 is 16
To do this problem you need to first find out how much 1/5th of 20 is. Which we can do by multiplying 20 x 1/5 which will give us 4. Since $4 is 1/5 of the total amount and we need 4/5th this value, we can multiply 4 x 4 to get $16 saved in total.

\(Simplify (2x-7)(x+3)-(-3x^{2} -4)\)
Answers
Answer:
\(5x^2 - x - 17\)
Step-by-step explanation:
Distribute the terms inside the first set of parentheses:
\((2x - 7)(x + 3) = 2x^2 + 6x - 7x - 21\)
Combine like terms:
\(= 2x^2 - x - 21\)
Simplify by adding the second part:
\(2x^2 - x - 21 - (-3x^2 - 4)\)
Subtracting a negative is the same as adding the positive equivalent:
\(= 2x^2 - x - 21 + 3x^2 + 4\)
Combine like terms:
\(= 5x^2 - x - 17\)
(2x-7)(x+3)-(-3x^[2] - 4)
====
5x^[2] -x -17
To begin simplifying this expression, we will foil the first half of it:
(2x-7)(x+3)
2x*x + 2x*3 - 7*x - 7*3
2x^[2] + 6x - 7x - 21
With this, we combine like terms:
2x^[2]-x-21
We now have
2x^[2]-x-21-(-3x^[2]-4)
We can now do the binomial distribution in the second half of the expression. Remember, the - sign in front of the parentheses means we are negating everything inside. In other words, we are multiplying -1 by everything inside the parentheses. Following this:
-(-3x^[2]-4) becomes
-1*-3x^[2] + -1*-4 = 3x^[2]+4
We have now simplified the first and second half of our expression, so we have:
2x^[2]-x-21+3x^[2]+4
And combining like terms we get
2x^[2]+3x^[2]-x-21+4 =
5x^[2] -x -17
We can use the quadratic expression to determine if the trinomial can be factored evenly, but it cannot so we have our final simplifed expression!

A cooking magazine shows a photo of a main dish on the front cover of
5 out of the 12 issues it publishes each year. Write and solve a proportion
to determine how many times a photo of a main dish will be on the front
cover during the next 5 years.
Answers
Answer:
Step-by-step explanation:
Based on the number of times the photo appears per year, in 5 years it will appear 25 times.
Every year, the photo in question appears 5 out of 12 times.
If there were 5 years therefore, it would appear:
= Number of times per year x Number of years
= 5 x 5
= 25 times
In conclusion, the photo of a main dish will appear 25 times in 5 years.

How can I find the cube root of 64?
Answers
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

Answer:
pls give me brainliest
Step-by-step explanation:
A compound event is an event where there are more than 1 type of possibilities. for example, a non compound event like tossing a coin, has only 2 outcomes, either heads or tails, this is one possibility, but while tossing a die, there are various possibilities, like p(getting 1), p(getting even number), p(getting prime number), etc. this is known as a compound event.
a sample space is is where all outcomes of an event is enlisted, for example in tossing a die, sample space is {1,2,3,4,5,6}. and sample space for tossing a coin, {H,T}. Note : if 2 dices are tossed, the number of possibilities or 6^2, because there are 6 possibilities in one die and it will be 6^2 if there are 2.
a tree diagram helps in easily writing down the outcomes easily, here is an example.

Answers
Answer: 9, 11 (or for the picture 48 and 52)
Step-by-step explanation:
The sum of two numbers (x, y) is 20;
x+y=20
One is 2 greater than than the other;
y=x+2
Now, we can put that in for y;
x+(x+2)=20
And solve;
2x+2=20
2x=18
x=9
Now, substitute in the value of x into the second equation;
y=9+2
And we get our answer.

Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A
Amal usually brings lunch to the school in the lunch box shown below. The length, breadth, and height of the box are in the ratio of 2:3:4 and the sum of the cubes of length, breadth, and height of the box equals 33957 cm³.
Find the length of the longest edge of the box.
Find the sum of the length and breadth of the box.
Answers
Answer: length of longest side = 15092 cm
sum of length and breadth = 18856 cm
Step-by-step explanation:
1st question
length : breadth : height
2 : 3 : 4
2 + 3 + 4 = 9
33957 ÷ 9 = 3773
longest side is the height because it has the biggest number in the ratio
∴ longest side = 4 × 3773 = 15092 cm
2nd question
length : breadth : height
2 : 3 : 4
2 + 3 + 4 = 9
33957 ÷ 9 = 3773
→ length = 2 × 3773 = 7546 cm
→ breadth = 3 × 3773 = 11319 cm
∴ length + breadth = 7546 + 11319 = 18865 cm
Hope this helps!
The Length of longest edge of the box = 28 cm
The Sum of length and breadth of the box = 35 cm
Steps to calculate the length, breadth and height
Given, ratio(length : breadth : height) = (2:3: 4)
Let length = 2x, breadth = 3x and, height = 4x
Given, the sum of the cubes of length, breadth, and height of the box equals 33957 cm, therefore
\((2x)^3\) + \((3x)^3\) + \((4x)^3\) = 33957
8\(x^{3}\) + 27\(x^{3}\) + 64\(x^{3}\) = 33957
99\(x^{3}\) = 33957
\(x^{3}\) = 343
\(x^3\) = \(7^3\)
x = 7.
Therefore, length = 2x = 2*7 = 14 cm, breadth = 3x = 3*7 = 21 cm, height = 4x = 4*7 = 28 cm. Hence, Length of longest side(height) = 28 cm, Sum of length and breadth = 35 cm
