If a+b=2 find the value of a3+b3+6ab
Answer:
Step-by-step explanation:
Factor the sum of cubes
a³ + b³ = (a+b)(a² - ab +b²)
= 2a² - 2ab + 2b²
a³ + b³ + 6ab = 2a² + 4ab + 2b²
= 2(a² + 2ab +b²)
= 2(a+b)²
= 8
Find the area of obtuse triangle ABC when A=41 degrees, a=18cm, and b=22cm.
Answer:
36 cm²
Step-by-step explanation:
cos A= (`sqrt(b)` + `sqrt(c)` - `sqrt(a)`)/(2bc)⇒c ≈ 5 cm
Sabc= (1/2)bcsin A ≈ 36 cm²

solve for a and B. A. a=400/21, b = 580/21 B. a=400/21, b=20/21. C a=580/21, b=20/21. D a=20/21, b=580/21
Answer:
Step-by-step explanation:
21/29 = 20/b
b = 20*29/21 = 580/21
a^2 + 20^2 = (580/21)^2
a = 400/21

Students from Shelton Middle are going on a field trip to an amusement park. Those students who have annual passes will pay $10. Other students will pay $35. The school collected $1,375 for 50 students. Which system of linear equations models this situation?
a) 10x + 35y = 50
x + y = 1,375
b) 10x + 35y = 1,375
x + y =50
c) 10x + y = 50
35x + y = 1,375
d) 10x + y = 1,375
x + 35y = 50
Answer:
c

3 5 5 15 17 20 what is the median
Answer:
Step-by-step explanation:
So find the middle number or middle two
Then if it’s one number it’s that number
If it’s two add them up and divide
In this case it’s 2:5 and 15
5+15=20
20/2=10
So the median is 10

i bought a box of fruit snacks worth $9.98, there are 90 packs of fruit snacks in the box. How much is each pack of fruit snacks worth ? please help
Answer:
About $0.11
This is because 0.11 is how much money one pack is Worth.
Answer:
Cost of each pack = $0.11
Step-by-step explanation:
Given information,
→ Total cost of the snacks = $9.98
→ Total packs in the box = 90 packs
Now we have to,
→ Find the cost of each pack.
Let us assume that,
→ Cost of each pack = x
Forming the equation,
→ x × 90 = 9.98
Then the value of x will be,
→ x × 90 = 9.98
→ 90x = 9.98
→ x = 9.98 ÷ 90
→ [ x = $0.11 ]
Hence, the value of x is 0.11.

4<x because the arrow is going to the right, meaning that the value of x is greater and since the circle is hollow, it is not equal to 4 so that's why is
4<x
Answer:
4 < x
Step-by-step explanation:
Open circle = < and >
Closed Circle = ≤ and ≥
X is greater than 4 because it is going to the right
Write a ratio equivalent to 21/35
Answer:
3:5
Step-by-step explanation:
Ratio are also fractions, so we can convert the fraction to a ratio like so:

Is 1/7 an irrational number?
Answer:
Yes
Step-by-step explanation:
1/7 = 0. 142857, where the bar over 142857 indicates a pattern that repeats forever. A real number that cannot be expressed as a quotient of two integers is known as an irrational number.
On average, employees at a particular company miss 1 day of work per year. That is 75% less than it was historically, back before there were major management changes. What was the average back then?
Answer:
4 miss days per year
Step-by-step explanation:
Let the previous employees miss days be = x
As given, miss days now are 75% less than previous
x - 75%x = 1/365
0.25x = 1/365
x = 1 / (365 x 0.25)
x = 4/365
So, average back then could have been 4 days per 365 days

Bus A travels according to the function y = 125 /2 x where y is distance traveled in miles and x is time in hours. Bus B travels according to the graph below, where the distance y is a function of time x . Which bus travels faster? Include all necessary calculations in your final answer.
Answer:
Bus B travels faster.
Step-by-step explanation:
The graph of the question in the attached figure
we know that
the linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
x ---> is the time in hours
y ---> is the distance in miles
In this problem we have
Bus A
The slope of the linear equation represent the speed of the bus
so
The speed of bus A is
Bus B
Find the slope
take two points from the graph
(0,0) and (3,200)
The formula to calculate the slope between two points is equal to
substitute
Compare the slope Bus A with the slope Bus B
therefore
Bus B travels faster.

Given the function f(x), what is the transformation f(x)+r, if r is a real number and r > 0?
A. The graph shifts r units down
B. The graph shift r units up
C. The graph shift r units right
D. The graph shift r units left
Answer:
C
Step-by-step explanation:
If r is a real number, then the x intercepts 0 < r, meaning r is greater than 0, you would shift right from 0 to your higher + number.
