Answer:
1/3x=14
answer for x is 42
Step-by-step explanation:
x represents the original number and 1/3 of the number equals 14. So 1/3x=14
So therefore 1/3x=14 which x = 42 in case if you were wondering.
New York City is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 3 vans and 14 buses with 509 students. High School B rented and filled 12 vans and 10 buses with 472 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.
Answer:
Step-by-step explanation:
Let's say :
v = number students in van, b = number of students in bus
From the info provided in the question:
High school A takes 3 vans and 14 buses for 509 students
We can write this as:
3v + 14b = 509
You can re-write this as :
3v = 509 - 14b
We also know High School B takes 12 vans and 10 buses for 472 students:
12v + 10b = 472
Since we already know that 3v = 509 - 14b , substitute this equation into the above formula and you get:
12v + 10b = 472
4(509 - 14b) + 10b = 472
2036 - 56b + 10b = 472
2036 - 46b = 472
2036 - 472 = 46b
1564 = 46b
Divide both sides by 46 to find "b".
b = 1564/ 46 = 34
Therefore the number of students that fit in each bus is 34.
So since we know b = 34, substitute b into the equation at the top:
3v = 509 - 14b
3v = 509 - 14(34)
3v = 509 - 476 = 33
Divide both sides by 3 to find "v".
v = 33/3 = 11.
Therefore the number of students in each van is 11.

Which ordered pair locates point P on the coordinate plane?
Answer:
(-3,-2)
Step-by-step explanation:
Answer:
The answer is A.
A is directly proportional to the square root of B
When A = 50, B+4 . Find A in terms of B
Answer:
A=50, B=4
A is directly proportional to the square root of B
name the constant 'k'
A = k*B^0.5
50 = k*4^0.5
50=2k
k=25
=> A =25 root B
i.e, A = 25*B^0.5 (The answer should be written the way it is written in the attached picture)
A written in terms of B is 25√B.
What is direct and inverse proportion ?In direct proportion if one quantity increases the other quantity also increases and vice versa.In case of inverse proportion when one quantity increases the other quantity decreases and vice versa.
According to the given question A is directly proportional to the square root of B.
∴ A = K[tex]\sqrt{B}[/tex]
Given when A = 50 B = 4.
50 = K[tex]\sqrt{4}[/tex]
50 = 2k
k = 25.
So, A =25√B.

The pizza shop is running a special: 2 medium pizzas
for $6.99 each. How much would it cost to by 12
pizzas?
Answer:
41.94
Step-by-step explanation:
12 divided by 2 is 6 and six times 6.99 gets you your answer of 41.94
Answer:
$72.00
Step-by-step explanation:
Lets round $6.99 to $7.00. Now we have an easier number to work with.
To find the total price of 12 , we need to multiply $7.00 by 12.
⇒ $7.00 x 12 = $84.00
Since we added 1 cent to $6.99 and multiplied by 12, we need to sutract 1 times 12.
1 x 12 = 12
$84 - $12 = $72.00

A concentrated cleaning solution must be mixed with water in a container that allows users to spray onto the surfaces they need to clean. Pam’s mom asked her to add 30 ounces of cleaning concentrate into the sprayer and then add water to fill the sprayer. Her father told her that the sprayer must contain 20% cleaning concentrate and 80% water.
a. How many ounces does the sprayer hold?
ounces
b. How much water was added to the sprayer?
ounces
Answer: The sprayer can hold 150 ounces, and Pam needs to add 120 ounces of water.
Step-by-step explanation:
The data that we know is:
We must use 30 oz of cleaning concentrate.
The end product must be 80% water and 20% cleaning concentrate.
This means that:
Mass of water/total mass in the sprayer = 0.8
mass of cleaning concentrate/total mass in the sprayer = 0.2
Then, let's define the variables:
X = ounces that the sprayer can hold.
Y = ounces of water added.
Then we have the equations:
30oz + X = Y.
30oz/Y = 0.20
X/Y = 0.80
From the second equation we can find the value of Y.
30oz = 0.20*Y
30oz/0.20 = Y = 150oz.
Then the sprayer can hold 150 ounces.
Now from the third equation we have:
X/Y = 0.8
We know that Y = 150oz
Then:
X/150oz = 0.8
X = 0.8*150oz = 120 oz.
Then the water that must be added is 120 ounces.
