Explanation:
Divide by the smallest prime 2
90/2 = 45
Then divide by the next smallest prime 3 (since 2 won't go into 45)
45/3 = 15
Repeat the last step
15/3 = 5
We stop because the result is prime.
Note the denominators are 2, 3, 3. The final result is 5 which is prime.
So the prime factors are 2, 3, 3, and 5
They multiply to 2*3*3*5 = 90.
We can condense it to 2*3^2*5 = 90 because 3*3 = 3^2.
Answer and Step-by-step explanation:
The prime factorization of 90 is 2 × 3 × 3 × 5 or 2 × 32 × 5, where 2, 3, and 5 are the prime numbers. You can find "prime factorization" by following two simple steps. Step 1: Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers. Step 2: Write the number as a product of prime numbers.

For a given recipe, 10 cups of flour are mixed with 20 cups of sugar. How many cups of flour should be used if 4 cups of sugar are used? Assuming a constant ratio, fill out the table of equivalent ratios until you have found the value of x.
Answer:
2
Step-by-step explanation:
If 20 cups are used on the first recipe then 4 are used on the second, the way to find the answer is to divide 20 by 4. 20 divided by 4 will get 5. Now we have to divide the 10 cups of flour by 5 which in the end will get 2.

factorise 9(a+b)^2 + (a+b) -8
Answer:
[tex](9a+9b-8)(a+b+1)[/tex]
Step-by-step explanation:
[tex]9(a+b)^2 + (a+b)-8[/tex]
Expand [tex](a+b)^2[/tex]
[tex]9(a^2+2ab+b^2)+a+b-8[/tex]
[tex]9a^2+18ab+9b^2+a+b-8[/tex]
Now it is time to think.
Once
[tex]9a^2=9a \cdot a[/tex]
[tex]9b^2=9b \cdot b[/tex]
[tex]18ab=9ab+9ab[/tex]
[tex]-8=-8 \cdot 1[/tex]
We can get something in the format
[tex](9a+9b-8)(\text{some expression here})[/tex]
From the conclusions above,
[tex](9a+9b-8)(a+b+1)[/tex]
4a−2(3a+8)=6 what is the answer
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{a = - 11}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{4a - 2(3a + 8) = 6}[/tex]
Distribute 2 through the parentheses
[tex] \longrightarrow{ \sf{4a - 6a - 16 = 6}}[/tex]
Collect like terms
[tex] \longrightarrow{ \sf{ - 2a - 16 = 6}}[/tex]
Move 16 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{ - 2a = 6 + 16}}[/tex]
Add the numbers: 6 and 16
[tex] \longrightarrow{ \sf{ - 2a = 22}}[/tex]
Divide both sides by 2
[tex] \longrightarrow{ \sf{ \frac{ - 2a}{ - 2} = \frac{22}{ - 2}}} [/tex]
Calculate
[tex] \longrightarrow{ \sf{a = - 11}}[/tex]

How do i find the vertex of the equation y=(x+5)(x+4)?
Answer:

y=(x+5)(x+4)=x²+5x+4x+20=x²+9x+20=x²+9x+(9/2)²-(9/2)²+20
[tex]y=(x+\frac{9}{2} )^2-\frac{81}{4} +20\\y=(x+\frac{9}{2})^2-\frac{81}{4}+\frac{80}{4}\\y=(x+\frac{9}{2})^2-\frac{1}{4}[/tex]

A text font fits 12 characters per inch. Using the same font, how many characters can be expected per yard of text? There are 12 inches in a foot, and 3 feet in a yard. 36 characters 144 characters 360 characters 432 characters
432 characters can be expected to fit per yard of text. Therefore, option D is the correct answer.
Given that, a text font fits 12 characters per inch.
We need to find how many characters can be expected per yard of text.
How to convert yards to inches?To convert a yard measurement to an inch measurement, multiply the length by the conversion ratio. The length in inches is equal to the yards multiplied by 36.
Let x be the number of characters to be used in a yard.
12 characters / in = x/ 36 in
(12 characters * 36 in) / in = x
x = 432 characters
Therefore, option D is the correct answer.

Amy buy 5 pounds potatoes for $2.50. How much does 1 pound of potatoes weight? (What is the unit rate?)
Answer:
$0.50
Step-by-step explanation:
If there are 5 pounds of potatoes for $2.50, you must divide to find the unit rate.
$2.50 / 5 = $0.50
1 pound of potatoes costs $0.50
Answer:
0.5 $/pound
Step-by-step explanation:
[tex]5[/tex] pounds ⇒ [tex]2.50$[/tex]$to khow much dollars one 1 pound costs, we must divide the price of 5 pounds by 5
[tex]\frac{2.50}{5} = 0.5[/tex] $/ pound2.5 is in dollars and 5 is in pounds so the rate unit is $/pound
Use the Distributive Property to simplify. s 5 a solution to 2t - 1 = 11?
Answer:
5 is NOT a solution to the equation.
t = 6
Step-by-step explanation:
Step 1: Write out equation
2t - 1 = 11
Step 2: Add 1 to both sides
2t = 12
Step 3: Divide both sides by 2
t = 6

The slope of the line represented by the equation 2(x - 3) - 6y = 10 is
equal to what?
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
The equation of the line is;
2(x - 3) - 6y = 10
Placing the line in slope intercept form we get;
6y = 2x - 6 - 10
6y = 2x - 16
Dividing throughout by 6 we get;
y = [tex]\frac{2}{6}[/tex]x - [tex]\frac{16}{6}[/tex]
Simplifying gives;
y = [tex]\frac{1}{3} x +2 \frac{2}{3}[/tex]
So the slope of this line = [tex]\frac{1}{3}[/tex]

Are the equations – 2x = 10 and -5x = 25 equivalent?
Answer: [tex]Yes[/tex]
Q: How are they the same answer?
A: You divide both of them by the number with x.
Divide both sides by -2
[tex]-2x/-2=10/-2\\x=-5[/tex]
Divide both sides by -5
[tex]-5x/-5=25/-5\\x=-5[/tex]
That's how both of them are equivalent to each other.

The measure of two vertical angles are given by the expressions (x+3) and (2x-7). Find the value of x.
Answer:
61.3
Step-by-step explanation:
two vertical angles add up to 180°
so (x+3)+(2x+7)=180°
open brackets & collect like terms
x+3+2x-7=180°
3x+-4=180°
3x=184°
x=61.3 after dividing by 3 on both sides
If y is directly proportional to x and y = 6 when x = 2, what is the proportion equation?
Answer:
y = 3x
Step-by-step explanation:
Direct proportion equation is
y = kx
6 = k*2
Divide each side by 2
6/2 = 2k/2
3 =k
The equation is y = 3x
Formula for direct proportion: y = kx
Solution:
6 = 2k
~Divide 2 to both sides
3 = k
