Answer:
8n < 72
n < 9
Step-by-step explanation:
Note that
> means greater than
< means less than
≥ means greater than or equal to
≤ less than or equal to
for example : 2 < 3 means 2 is less than 3
3 >2 means 3 is greater than 2
8 times n = 8n
8n is less than 72, this can be represented by the equation : 8n < 72
to determine the value of n, divide both sides of the equation by 8
n < 9

Step-by-step explanation:
Factor out x + 2.
You get: (x + 2)(3x - 4)
Now multiply it out:
(x + 2)(3x - 4) = 3x^2 - 4x + 6x - 8 = 3x^2 + 2x - 8

What's The actual length of UV (round to 3 decimal places) ?
Answer:
7.463 cm
Step-by-step explanation:
Use the pythagorean theorem (a^2 + b^2 = c^2) to find the side length of UV.
a^2 + b^2 = c^2
6.1^2 + 4.3^2 = 55.2
Then square root 55.2, which is 7.463 cm

Louis bought 16 cookies at the bakery. He had a
coupon for $7 off his entire purchase. He ended up
paying $13.32. Write an equation to find how much
each cookie originally cost.
16c-[?] = []
Answer:
16c - 7 = 13.32
Step-by-step explanation:
The cost of 16 cookies minus the coupon equal how much he paid
16c - 7 = 13.32
Answer:
16c - 7 = 13.32
Step-by-step explanation:
The cost of a ticket increases by 10% to£18.15
Work out the original cost
Let the original price = x
An increase of 10 % = 18.15
Multiply x by (1 + percent increase) which is 1.1x = 18.15
Now to find x divide both sides by 1.1:
X = 16.50
The original price was 16.50
Answer:
£16.50
Step-by-step explanation:
Let cost price be x
Now, create a formula:
x + 10x / 100 = 18.15
'or'
110x / 100 = 18.15
'or'
x = (18.15*100) / 110
x = 16.5

Answer:

Step-by-step explanation:
To find how many perennials there are, multiply the amount of plants by the percent of perennials. When you multiply percents, just put the percent behind the decimal
60x0.35=21
There are 21 perennials
Do the same for the biennials:
60x0.25=15
Therefore 15 biennials
Subtract the amount of perennials from the amount of biennials
21-15=6
There is 6 more perennials than biennials
Answer:
the answer is 6
21-15=6
Step-by-step explanation.
35% of 60 = 21 for perenalis
25% of 60 = 15 for biennials
40% of 60 = 24 for annuals
Today,high tide measured 5.5 ft and low tide measured 1 ft. What is the amplitude of a cosine function modeling the depth of the water in feet as a function of time in hours
Answer:
[tex]A = 2.25ft[/tex]
Step-by-step explanation:
Given
[tex]High = 5.5ft[/tex]
[tex]Low = 1ft[/tex]
Required
The amplitude (A)
This is calculated as:
[tex]A = \frac{1}{2}(High - Low)[/tex]
So, we have:
[tex]A = \frac{1}{2}(5.5ft - 1ft)[/tex]
[tex]A = \frac{1}{2} * 4.5ft[/tex]
[tex]A = 2.25ft[/tex]
Given the following information, determine which lines are parallel and what justifies them being parallel.
Answers:
Blank 1 = p and q
Blank 2 = Consecutive interior angles converse
=================================================
Explanation:
There's a lot of visual noise here, meaning there's a lot of lines and angles to potentially distract. I recommend redrawing things but only drawing lines p and q, and the transversal cut line t. Furthermore, I would mark only angle 8 and angle 13. See the diagram below.
The diagram is optional, but hopefully you can see that the angles are same side interior angles, aka consecutive interior angles. That's why we go with the consecutive interior angles converse
If we drop the "converse" portion, then that theorem says parallel lines lead to supplementary consecutive interior angles. The converse just reverses the flow of the logic.

Factorise fully 2a^2b + 6ab^2
Answer:
Step-by-step explanation:
2a^2b + 6ab^2
take common
2 can be taken common because there is 2in first term and there is 6 in second term and 2 can exactly divide 6 .there is a*a in first term and only a in second term so u can take a as common.There is only b in first term and b*b in second term so take u can take b as common.
total we can take
2ab as common.So,
2ab(a+3b)
therefore 2ab(a+3b) is the required answer.
The required factorization is 2ab(a+3b).
What is factorization?Factorization in mathematics is the process of dividing a large number into smaller ones that, when multiplied together, give you the original number. Factorization is the process of dividing a number into its components or divisors.
Expanding brackets in reverse is a procedure known as factorizing.
Fully factorizing an equation entails putting it in brackets by eliminating the components with the highest common denominator.
Finding the highest common factor between all the terms in the phrase is the easiest technique to factorize.
We have, 2a²b + 6ab²
Here,
we have the highest common factor 2ab,
So, 2ab (a + 3b)
Therefore, 2ab(a+3b) is the required factorization.
