Answer:
8x - 4
Step-by-step explanation:
Perimeter is the sun of all side lengths. We know the perimeter and two side lengths, so on order to find the third, we need to subtract the first two lengths from the sum. After subtraction, we get 8x - 4.

if y=3 then 14y equals
Answer:
42
Step-by-step explanation:
14(3)
Answer:
42
Step-by-step explanation:
first, substitute 3 for y in 14y. 14y means you are multiplying 14 and y, so when you plug in 3 for y, you're multiplying 14 and 3! :)
14y ⇒ 14(3)simplify by multiplying 14 · 3.
14(3) = 42so, when y = 3, 14y = 42.
you can check the answer by solving for y in 14y = 42.
divide both sides of the equation by 14.
14y/14 = 1y or y42/14 = 3after dividing, you're left with y = 3. that means 14y does indeed equal 42 when y = 3! :)

Geometry help please and thank you
Answer:
125°
Step-by-step explanation:
By exterior angle theorem:
(3x - 70)° = 60° + x°
(3x - 70)° - x°= 60°
(3x - 70 - x)° = 60°
(2x - 70)° = 60°
2x - 70 = 60
2x = 60 + 70
2x = 130
x = 130/2
x = 65
(3x - 70)° = (3*65 - 70)° = (195 - 70)° = 125°
[tex] m\angle LKM = 125\degree [/tex]

Step-by-step explanation:
A farmer wants to fence a piece of his land. Two sides of the triangular field have lengths of 120 feet and 325 feet. The measure of the angle between those sides is 70 degrees. How much fencing will a farmer need?
Farmer need 750.5 feet fencing for his triangular field.
What is triangle?"Triangle is two dimensional geometrical shape with three sides and three vertices. Sum of all the angles of a triangle is equals to 180°.
Formula used
Cosine rule
As per the diagram,
cosθ = (b² +c² -a²) / 2bc
cos 70° = 0.3420
According to the question,
Let AB = c , AC = b are given sides of measure 120 feet and 325 feet respectively.
and BC = a
Angle between given sides be θ = 70°
Substitute the value in the formula we get,
cos70° = [ (325)² +(120)² - a²] / 2(120)(325)
⇒ 0.3420 = [ 120025 - a²] / 78000
⇒ 120025 -a² = 26676
⇒ a² = 93349
⇒ a = 305.5
Total fencing required for triangular field = AB + BC +CA
= 120 + 325 + 305.5
= 750.5 feet
Hence, farmer need 750.5 feet fencing for his triangular field.

Mike has a 32 ounce drink. He drinks 8 ounces. Select the percent of ounces Mike has left from his drink
Answer:
75%
Step-by-step explanation:
the percentage amount of the drink that mike drank is calculated by dividing the total drink by the amount drank. In this case that is 8/32 which gives us 0.25 or 25%.
In order to find the amount Mike has left you simply subtract the amount drank from the 1 as 1 is equal to 100% or the amount mike had at the begining. In this case 1-0.15= 0.75 or 75%.
OR
you can also solve this by subtracting tha amount drank by the total then dividing the remaining drink by the total amount of the drink. In this case that would look like:
32-8= 24
24/32= 0.75
The social studies teacher wants to know whether the students in the entire school prefer a model United Nations activity or a student government activity. The teacher draws a random sample from the following groups: All teachers in the school All boys in each grade All students in each grade All students in the social studies club Which group best represents the population he should take a random sample from to get the best results for his survey?
All teachers in the school
All boys in each grade
All students in each grade
All students in the social studies club
Answer:
all students each grade, its a better representation of the wants of the whole group being affected
Step-by-step explanation:
Answer:
C: All students in each grade
Step-by-step explanation:
It cant be all teachers in the school since at the beginning of the question it says "whether the students" not whether the teachers plus it is not a mxed variety, so this question was sort of trying to catch you off guard
The reason why is if you pick all the boys in each grade then it wouldnt really be random since your picking the gender you want to answer it has to be a mixed variety all ages all genders and so on
Yes! All students in each grade would be a mixed variety since its all ages, all genders, and all grades this answer was a little obvious since they sort of gave you the answer saying "The social studies teacher wants to know whether the students in the entire school"
All students in the social studies club wouldnt be a good answer either since (as i said before) it has to be random and your picking who you want to answer plus since there in the club with the social studie steacher they are more likely to pick what she wants to pick
So the answer would be C: All students in each grade

A circular running track is 1/2 mile long. Elena runs on this track completing each lap in 6 minutes how long will it take Elena to run 3 miles?
Answer:
36 mins
Step-by-step explanation:
0.5 miles/6 mins = 3 miles/x mins
In order to convert the ratio from 0.5 miles to 3 miles, 0.5 was multiplied by 6. Therefore, to keep the ratio the same, 6 minutes must also be multiplied by 6 to find x. This means the answer is:
3 miles/36 mins
