Answer:
the value of 1 by 3- 1 by 2 is 1
Step-by-step explanation:
it is one because 1 by 3 is 1*3
that equals to 3
then you do 1 by 2 (aka 1*2)
then it is 3-2 which equals to 1

Is 5:2 the same as 2:5
Answer:
It is not the same
Step-by-step explanation:
Is 5/2 greater than 2/5? Is 5/2 bigger than 2/5? Is 5/2 larger than 2/5? These are all the same questions with one answer.
When comparing fractions such as 5/2 and 2/5, you could also convert the fractions (if necessary) so they have the same denominator and then compare which numerator is larger.
To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as illustrated below: 5/2 = 2.5
2/5 = 0.4 Therefore, 5/2 is greater than 2/5 and the answer to the question "Is 5/2 greater than 2/5?" is yes.
Step-by-step
Its different because 5:2 and 2:5 (or 5/2 and 2/5) have different numerators and denominators.
Kyle is making a frame for a rectangular piece of art. The length of the frame is 3 times the width, as shown below. A rectangle with a length of 3 x and height of x. If Kyle uses 18 feet of wood to make the frame, what is the length of the frame? Write the answer in decimal form.
Given :
A rectangle with a length of 3 x and height of x. If Kyle uses 18 feet of wood to make the frame.
To Find :
The length of the frame.
Solution :
We know, perimeter of the rectangle is given by :
[tex]P=2(l+b)\\\\P=2(3x+x)\\\\P=8x[/tex]
Now, it is given that 18 feet of wood is used.
So,
[tex]8x=18\\\\x = 2.25\ feet[/tex]
Therefore, length of frame is given by 3x = 6.75 feet.
Hence, this is the required solution.
Answer: A, 6.75
Step-by-step explanation: If the frame is 3 times the width and Kyle uses 18 feet them this the only correct option out of the other 3.
2x - 1y = 6
-3y = -6x + 18
please explain how you got your answer thank you :)
Answer: {x,y}={6,21}
Step-by-step explanation:
// Solve equation [2] for the variable x
[2] 3x = 18
[2] x = 6
// Plug this in for variable x in equation [1]
[1] 2•(6) - y = -9
[1] - y = -21
// Solve equation [1] for the variable y
[1] y = 21
// By now we know this much :
x = 6
y = 21
We are done
Answer:
y = 2x -6. A dependent system, so all numbers on this line.
Step-by-step explanation:
2x - y = 6
-3y = -6x + 18
In order to solve a system of equations, you want to get isolate y. One equation already has done that for us, so that makes it easier.
2x - y = 6
In order to isolate y in this equation, you must simply subtract 2x from both sides, which would give us:
-y = -2x + 6
Now, you can't leave y negative. Normally you'd divide the y by its variable, but this one doesn't have a variable. so you must divide both sides by -1.
[tex]\frac{-y}{-1} =\frac{-2x+6}{-1}[/tex]
We divide both sides because what you do to one side you must do to the other. This leaves us with the equation:
y = 2x - 6
Now, for the other equation. It's simple since y is already isolated.
-3y = -6x + 18
Once again we will be dividing both sides, but this time it's by -3.
[tex]\frac{-3y}{-3} =\frac{-6x+18}{-3}[/tex]
We are dividing by -3 instead of -1 because y in this equation has a variable of -3. This would give us:
y = 2x - 6
Now, normally in order to get the answer, you must graph both of these equations, but since these equations ended up being the same, the answer is every number that appears on the line. This is called a dependent system.

✺ Divide both sides by −3. Since −3 is negative, the inequality direction is changed:
-3 ÷ -3 = Cancels OutTurns into: [tex]\frac{-9}{-3} >5x-2[/tex]✺ Divide −9 by −3 to get 3. Since they are both negatives it turns into a positive:
-9 ÷ -3 = 3Turns into: [tex]3 > 5x - 2[/tex]✺ Swap sides so that all variable terms are on the left hand side. This changes the sign direction once more:
Turns into: [tex]5x-2<3[/tex]✺ Add 2 to both sides:
Turns into: [tex]5x<3+2[/tex]✺ Add 3 and 2 to get 5:
3 + 2 = 5Turns into: [tex]5x<5[/tex]✺ Divide both sides by 5. Since 5 is positive, the inequality direction remains the same:
5 ÷ 5 = Cancels OutTurns into: [tex]x<\frac{5}{5}[/tex]✺ Divide 5 by 5 to get 1:
5 ÷ 5 = 1✺ So your answer is B, [tex]\boxed{x<1}[/tex].

Answer:
[tex]\boxed {x < 1}[/tex]
Step-by-step explanation:
Solve the following inequality:
[tex]-9 < -3(5x - 2)[/tex]
-When you are dividing an integer by a negative integer, then the inequality sign changes. So, divide both sides by [tex]-3[/tex]:
[tex]\frac{-9}{-3} < \frac{-3}{-3} + 5x - 2[/tex]
[tex]3 > 5x - 2[/tex]
-Switch sides:
[tex]5x - 2 < 3[/tex]
-Add [tex]2[/tex] to both sides:
[tex]5x - 2 + 2 = 3 + 2[/tex]
[tex]5x < 5[/tex]
-Divide both sides by [tex]5[/tex]:
[tex]\frac{5x}{5} < \frac{5}{5}[/tex]
[tex]\boxed {x < 1}[/tex]

3. A water balloon was thrown
from a window. The height
of the water balloon over
time can be modeled by the
function y= 16x2 + 160x + 50.
What was the maximum
height of the water balloon
after it was thrown?
Note: It the given equation the coefficient of [tex]x^2[/tex] must be -16 instead of 16.
Given:
Consider the height of the water balloon over time can be modeled by the function
[tex]y=-16x^2+160x+50[/tex]
To find:
The maximum height of the water balloon after it was thrown.
Solution:
We have,
[tex]y=-16x^2+160x+50[/tex]
Here, leading coefficient is negative. So, it is a downward parabola and vertex of a downward parabola, is the point of maxima.
If a parabola is [tex]f(x)=ax^2+bx+c[/tex], then
[tex]Vertex=\left(-\dfrac{b}{2a},f(-\dfrac{b}{2a})\right)[/tex]
Here, [tex]a=-16,b=160,c=50[/tex]. So,
[tex]-\dfrac{b}{2a}=-\dfrac{160}{2(-16)}[/tex]
[tex]-\dfrac{b}{2a}=-\dfrac{160}{-32}[/tex]
[tex]-\dfrac{b}{2a}=5[/tex]
Now, put x=5 in the given equation.
[tex]y=-16(5)^2+160(5)+50[/tex]
[tex]y=-16(25)+800+50[/tex]
[tex]y=-400+850[/tex]
[tex]y=450[/tex]
The vertex of the given parabolic equation is (5,450).
Therefore, the maximum height of the balloon is 450 units after 5 units of time.
Two students are having a party. They want to make treat bags for their guests. They want each bag to be identical with nothing leftover. They have 36 Silly Bandz and 72 pieces of Double Bubble to put in the bags. What is the greatest number of treat bags they can make? How many of each item will be in each treat bag?
Answer:
Two students can make maximum 36 treat bags.
Number of pieces of silly Bandz in each bag [tex]=1[/tex]
Number of pieces of Double Bubble in each bag [tex]=2[/tex]
Step-by-step explanation:
Number of pieces of silly Bandz = 36
Number of pieces of Double Bubble = 72
To find greatest number of treat bags that they can make, find H.C.F. of 36 and 72
[tex]36=(2^2)(3^2)\\72=(2^3)(3^2)[/tex]
[tex]H.C.F(36,72)=36[/tex]
So,
they can make maximum 36 treat bags.
Number of pieces of silly Bandz in each bag [tex]=\frac{36}{36}=1[/tex]
Number of pieces of Double Bubble in each bag [tex]=\frac{72}{36}=2[/tex]

Insert the parenthesis to make the equality right:630÷7÷2⋅9⋅25=125
Answer:
(630 ÷ 7) ÷ (2 ⋅ 9) ⋅ 25 = 125
Step-by-step explanation:
630 ÷ 7 ÷ 2 ⋅ 9 ⋅ 25 = 125
(630 ÷ 7) ÷ (2 ⋅ 9) ⋅ 25 = 125
90 ÷ 18 ⋅ 25 = 125
5 ⋅ 25 = 125
125 = 125

Answer: For 5 pirate ships, you need 55 pirates. For 11 pirate ships, you need 121 pirates.
Step-by-step explanation:
22 (# of pirates) divided by 2 (# of ships) = 11 pirates per ship. Use this knowledge of 11 pirates per ship to find how many pirates you need for different numbers of ships:
11*5= 55 for 5 ships &
11*11= 121 pirates for 11 ships.
Basic math equations and calculations play an important role in many jobs tasks. If you were working at a grocery store and your cash register was not automatically calculating the 20% off sale on someone's cereal--how would you solve this issue from the options listed below? If the cereal was normally $2.88, I would... 1 point Take $2.88 and times it by 80 for a sale price of $2.30. Subtract $0.20 for a sale price total of $2.68. Divide 20 from $2.88 for a sale price total of $0.15.
Given :
Price of cereal without off, C = $2.88 .
Percentage off, P = 20% .
To Find :
Price after applying 20% off.
Solution :
Final price = Initial price - 20 % of initial price
[tex]F = 2.88 - 2.88\times \dfrac{20}{100}\\\\F=2.88-0.576\\\\F=\$ 2.304[/tex]
Therefore, final price after sale is $2.304 .
Hence, this is the required solution.
A new uniform cost 49.99 if its on sale for 15% off what is the cost before tax
Answer:
$42.49
Step-by-step explanation:
This means the cost of the item to you is $42.49. You will pay $42.49 for a item with original price of $49.99 when discounted 15%. In this example, if you buy an item at $49.99 with 15% discount, you will pay 49.99 - 7.4985 = 42.49 dollars.
Answer:
42.49
Step-by-step explanation:
Discount = 15% of 49.99
= 0.15 * 49.99
= 7.4985
Cost after discount = 49. 99 - 7.4985
= 42.4915
= 42.49
Complete the square:
