Find the least common multiple of 9 and 15
Answers
Answer:
45
Step-by-step explanation:
9:9,18,27,36,45
15:15,30,45
Answer:
45
Step-by-step explanation:
The least common multiple is the smallest number found between the two numbers, in this case 9 and 15, while skip counting from each number. Or the like the multiplication table.
Multiples for 9:
9, 18, 27, 36, 45, 54, 63...
Multiples for 15:
15, 30, 45, 60, 85...
45 is the first and common number that appears in both multiples of 9 and multiples of 15. Therefore, it will be the least common multiple of 9 and 15.
The expression 146 - 144 is equal to
O 142

14 10
Answers
Step-by-step explanation:
I am sure you mistyped something here and/or there is something missing.
because 146 - 144 = 2
and nothing in the answer options shows anything like it.
now, if the problem actually said for example
14×6 - 14×4
that could be expressed as
14×(6-4) = 14×2
and that could be the first answer option (also with missing multiplication symbol).
Find the minimum value of the function:
f(x) = x2 + 9x – 16.
Answers
(x + 4.5)^2
This will give us an extra 20.25 we don’t want, so takeaway 20.25:
(x + 4.5)^2 — 20.25
Takeaway the 16 in the question:
(x + 4.5)^2 - 20.25 - 16 = (x + 4.5)^2 - 36.25
The minimum x coordinate is the number in the bracket with the opposite sign, thus the answer is -4.5 (the minimum y coordinate is the number outside the bracket with the same sign, -36.25)

If it costs $5.35 per day for a 5 day work week to ride the bus, and a weekly pass is $25, how much could a person save by buying the pass?
Answers
Answer:
$1.75
Step-by-step explanation:
basically we are comparing
5 daily passes vs. a weekly pass.
5 daily passes = 5×$5.35 = $26.75
a weekly pass = $25.00
so, the difference is 26.75 - 25 = $1.75
The first thing you need to do in this problem is calculate how much it would cost to ride the bus 5 days a week WITHOUT the pass. Since you know there are 5 days in a week, and each day costs 5.35 dollars, multiply those two numbers together.
5*5.35= $26.75
Now, we are trying to find out how much more that is than the bus pass, since we are trying to find how much you can save by buying the bus pass. To do that, subtract 25 dollars (the cost of the bus pass) from the cost without the bus pass (26.75 dollars.)
26.75-25=1.75
Therefore, your answer is the first one: $1.75

The height of
the
glass
is 7cm and radius is 3cm if the glass is half filled with water find the height of the water.find the area of the water
Answers
Hey there! I'm happy to help!
This glass is most likely a cylinder. To find the volume of a cylinder you take the area of the circle base and multiply it by the height.
To find the area of a circle, you square the radius and multiply it by pi (we will use 3.14 for pi).
Our radius is 3cm.
3
We square it.
3²=9
Multiply by 3.14.
9×3.14=28.26
Now that we have our circle base area, we multiply it by the height (7 cm).
28.26×7= 197.82
This is how many cubic centimeters the glass can hold if it is completely full. However, we want half full, so we can just divide by 2.
197.82/2=98.91
We can also multiply our circle base by 3.5, which will give us half of the full height.
So, the height of the water is 3.5 cm and the volume of the water is 98.1 cm³.

The length of a rectangle is three times its width. It the perimeter of the rectangle is 96m, find the length and breadth of the rectangle
Answers
Let the width, w = x m
So, according to the Question,
The length, l = 3x m
Perimeter of a rectangle = 2 (l + w) m
Perimeter of the rectangle = 96 m
It's equation will be,
2 (3x + x) m = 96 m
or, 4x m = 96/2 m
or, 4x m = 48 m
or, x m = 48/4 m
or, x m = 12 m
Therefore, the width and the length of the rectangle is 12 m and 3(12) m = 36 m respectively.
please answer this, I'd appreciate it
Simplify too
Answers
Answer:
A.) w² + 3w in²
B.) 28 in²
Step-by-step explanation:
A.)
Let w = width and l = length.
The area of a rectangle can be written as length · width (base · height). The problem informs us that the length of the rectangle is 3 inches greater than the width. Therefore, l can also be written as w + 3. We can use this to form a polynomial that represents the area of the rectangle.
A(rectangle) = lw = (w + 3) · w = w² + 3w
B.)
Use the polynomial we previously found to find the area.
A(rectangle) = (4)² + 3(4) = 16 + 12 = 28 in²

Answers
Answer:
12.75
Step-by-step explanation:
Given the equations
x - y = 3.5 → (1)
[tex]\frac{x+y}{2}[/tex] = 11 ( multiply both sides by 2 to clear the fraction )
x + y = 22 → (2)
Add (1) and (2) term by term to eliminate y
2x + 0 = 25.5
2x = 25.5 ( divide both sides by 2 )
x = 12.75
Substitute x = 12.75 into (2)
12.75 + y = 22 ( subtract 12.75 from both sides )
y = 9.25
The 2 numbers are 12.75 and 9,25
With the larger number being 12.75

Lauren spent $3.26 for lunch on Tuesday. She spent $3.56 on Wednesday and $3.29 on Thursday. Order the prices from greatest to least. Draw a number line to support my the answer
Answers
I kinda need points here so:/
The number line visually shows the order of the prices, with $3.56 on the right (the greatest), followed by $3.29, and then $3.26 on the left (the least).
$3.56 $3.29 $3.26
|------------|------------|
To order the prices from greatest to least, we'll compare the amounts spent on each day:
1. Wednesday: $3.56
2. Thursday: $3.29
3. Tuesday: $3.26
So, in order from greatest to least, the prices are:
$3.56 > $3.29 > $3.26
Now, let's represent this order on a number line:
$3.56 $3.29 $3.26
|------------|------------|
