Answer:
A. 21 / 29
Step-by-step explanation:
with reference angle X
base (b) = 21
hypotenuse (h) = 29
Now
Cos X = b / h
= 21 / 29

1. The list of ordered pairs represents a function: (12,6) (3,1) (2,-2) (5,10) (-8,-4) ( _, _)
Which of the following could be the missing ordered pair?
A. (2,1)
B. (12,7)
C. (-8,8)
D. (-3,-4)
2. Rita works at a gym where she gets paid $450 each week plus $15.50 for any new gym membership she sells. If y represents the total pay per week and x represents the number of new memberships sold, which of the following equations represents a higher rate per membership sold.
A. y =31/3x + 500
B. y =15x + 425
C. y =33/2x + 425
D. y =15.05x +475
Answer:
1. D
2. y = 15.50x + 450
Step-by-step explanation:
1. Since it is a function, the missing pair can't repeat input values with different output, therefore only option D is unique so is the correct choice.
2. x > (y - 450)/ 15.50
i) Rita gets paid $450 per week.
ii) She gets $15.50 for every new membership she sells.
iii) let y represent the total pay per week.
iv) let x represent the number of new memberships sold.
v) the equation representing total pay is y = 15.50x + 450.
vii) therefore the equation that represents a higher rate of membership sold is given by x > (y - 450)/ 15.50
Find two consecutive even integers such that the sum of the smaller and 3 times the larger is 330
I am so stuck please any one help
Answer:
The 2 numbers = 81 and 83
Step-by-step explanation:
As, one number = x
The other, because it's an even number and consecutive = x + 2
So the larger numbef here is x + 2
And they are saying 3 times x + 2 plus x = 330
So let's solve!
3 times x + 2 = 3(x+2) = 3x + 6
So we will add it to x = (3x + 6) +(x) = 4x + 6
So they are saying the sum of them will be 330
So, 4x + 6 = 330
4x = 330 - 6
4x = 324
x = 324/4
x = 81
So x is the first number = 81
And the second is x + 2 = 81 + 2 = 83
So the 2 numbers are 81, 83
Lets check!
3 times the bigger number = 83 x 3 = 249
We will add it to 81 and we will get 330
So, 249 + 81 = 330
So the answer is right

Step-by-step explanation:
An airplane begins decreasing its altitude as it approaches the runway. At time t=1, the pilot notes that he has an altitude of 30,000 feet. One minute later, his altitude drops to 29,450 feet. One minute after that, his altitude drops to 28,900 feet. Assuming this pattern continues, write a recursive formula for the altitude of the plane A(t) after t minutes.(1 point)
A(t)=30000+550(t−1)
A(t)=A(t−1)−550 for t>1, where A(1)=30000
A(t)=A(t−1)+550 for t>1, where A(1)=30000
A(t)=30000−550(t−1)
Answer: i think A(t)=30000−550(t−1)

2x+3y=4 y+3x=6
find x and y
Answer:
x=-3/2y+2
y= y=−3x+6
Step-by-step explanation:
solve for x.
2x+3y=4
Add -3y to both sides.
2x+3y+−3y=4+−3y
2x=−3y+4
Divide both sides by 2.
2x/2= -3+4/2
x= -3/2 y+2
solve for y.
y+3x=6
Add -3x to both sides.
3x+y+−3x=6+−3x
y=−3x+6

Find the next three terms of the following arithmetic sequence. -10, -3, 4, 11, (Three missing numbers)
Answer:
You can find the difference of two numbers easier if you take the absolute value of them (which is canseling out the negative or positive of them, and figuring out how far away from 0 they are) |-10| = 10, |-3| = 3, the difference between 10 and 3 is 7. The only problem that arises is now we are dealing with and negative and a positive, for this one you must see that to get from -3 to zero, you need to add 3, and to get from 0 to 4, you need to add 4, if you add 3, and then 4, you get 7
The difference between 10 and 3 is 7
The difference between -3 and 4 is 7
So naturally, the next number will be 4 + 7 = 11
Hope that helped!

Sinister Stan stole 3 3/4 oz of slime from Messy Molly, but his evil plans require 6 3/8 oz of slime. He stole another 2 3/5 oz of slime from Rude Ralph. How much more slime does Sinister Stan need for his evil plan?
Answer: 1/40
Step-by-step explanation:
Since we are told that Sinister Stan stole 3 3/4 oz of slime from Messy Molly and stole another 2 3/5 oz of slime from Rude Ralph. The total oz of slime stole would be:
= 3 3/4 + 2 3/5
= 3 15/20 + 2 12/20
= 5 27/20
= 6 7/20
We are told that his evil plans require 6 3/8 oz of slime, the amount needed for Sinister Stan for his evil plan would be:
= 6 3/8 - 6 7/20
= 6 30/80 - 6 28/80
= 2/80
= 1/40
Somebody help plz I need help
In this case, we need to substitute n with 10.
So, it is like this: f(10) = 3(10) + 4
f(10) = 3(10) + 4
f(10) = 30 + 4
f(10) = 34
If the points are (-10, 3), (-2, 10) what is the slope?
Answer:
= 7/ 8
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 10-3)/( -2 - -10)
= ( 10-3)/( -2 +10)
= 7/ 8

Find the nth term of this quadratic sequence.
3, 11, 25, 45
Answer:
3 , 11, 25, 45
Diff 8 14 20
Diff 6 6
The second differences are the same. The sequence is quadratic and will contain an n^2 term. The coefficient of n^2 is always half of the second difference. In this example, the second difference is 6. Half of 6 is 3 so the coefficient of n^2 is 3
therefore 3n^2
3 11 25 45
3n^2 3 12 27 48
Remainder 0 -1 -2 -3
Difference -1 -1 -1
linear sequence with nth term -n+1
so nth term of quadratic sequence in 3n^2-n+1

5/8 - 1/16= what’s the answer to this please help
Answer:
9/16
Step-by-step explanation:
(5/8 * 2/2) - (1/16 - 1/1)
10/16 - 1/16
10-1//16 = 9/16
5/8 - 1/16 = 9/16
(5*16) - (1*8) / 8 * 16
80-8/ 128
72/128
72/8
128/8= 9/16
5/8 - 1/16 = 9/16

Answer:
One solution
Step-by-step explanation:
maybe
Answer:
There is only one solution to the equation.
x = 0
Step-by-step explanation:
Let rewrite the following equation so that x will be separated from the other numbers. So we do the following......
[tex]\frac{x+4}{4} = \frac{x +3}{3}[/tex]
[tex]12(\frac{x+4}{4}) = 12(\frac{x +3}{3})[/tex]
[tex]3(x +4) = 4(x+3)[/tex]
[tex]3x +12 = 4x +12[/tex]
[tex]12 = 4x - 3x +12[/tex]
[tex]0 = x[/tex]
