Answer:
A
Step-by-step explanation:
cos x = adjacent side / hypotenuse
cos 60 = 9√2/2 / x
1/2 = 9√2/2 / x
x = 9√2
tan x = opposite side / adjacent side
tan 60 = y / 9√2/2
√3 = 2y / 9√2
9√6 = 2y
y = 9√6/2

2 bags of cement cost 3500 how many bags can one buy with 17500
Answer:
10
Step-by-step explanation:
2 → $3500
? → $17500
? = 17500 x 2 / 3500 = 3500/3500 = 10
OR
3500 → 2
3500/2 = 1750
17500/1750 = 10
Therefore, whatever method you use, you will get 10 as an answer.

Answer:
D) 39
Step-by-step explanation:
There are a couple of steps to this. First, note that you must plug in the given number that replaces x into the right side's x. After you find the answers, you must then subtract both answers to get your result.
First step, find g(8):
g(x) = 3x - 2
When x = 8,
g(8) = 3(8) - 2
Remember to follow PEMDAS, the order of operations. First, multiply, then subtract:
g(8) = (3 * 8) - 2
g(8) = (24) - 2
g(8) = 22
Next step, find g(-5):
g(x) = 3x - 2
g(-5) = 3(-5) - 2
g(-5) = (3 * -5) - 2
g(-5) = (-15) - 2
g(-5) = -17
Note that you are subtracting both numbers. When there are two negative signs directly next to each other, it becomes a positive:
22 - (-17) = 22 + 17 = 39
D) 39 is your answer.

Which statement is true about the prime polynomial 2x2 + 3x + 3?
It cannot be modeled with a rectangle.
It can be modeled with a square.
It cannot be modeled with all positive tiles.
It can only be modeled with an odd number of tiles.
Answer:
it cannot be modeled with a rectangle
Step-by-step explanation:
let's eliminate the wrong answers first
1. it cannot be modeled with all positive tiles --- this incorrect because it is all positive, so it CAN be modeled with all positive tiles
2. it can only be modeled with an odd number of tiles -- not true, because 2x^2 is even number of tiles
3. it can be modeled with a square -- to be modeled as a square, the polynomial have to be factored into square ie (x+2)², but cann't be factored as square, so again not true
therefore, first one is the answer. because you cannot factor the polynomial as such (x+2)(x+3), so it cannot be modeled with a rectangle.
Answer:
A: It cannot be modeled with a rectangle.

Step-by-step explanation:
To SUBTRACT fractions with like or the same denominator, just subtract the numerators then copy the common denominator. Always reduce your final answer to its lowest term.
10. What percent of 25 is 10? (1 point)
O10=r. 25: 40%
O 10=r. 25: 250%
025=x: 10; 40
025=r. 10; 250%
Answer:
40%
Step-by-step explanation:
To change a fraction into a percentage, multiply by 100% , then
[tex]\frac{10}{25}[/tex]
= [tex]\frac{10}{25}[/tex] × 100%
= 0.4 × 100%
= 40%

Answer:
The functions each have a positive Slope
a.)True, False
Step-by-step explanation:
Function A Slope: (y2-y1)/(x2-x1) = (7-3)/(2-1) = 4
Function B Slope: Count Four Boxes up from the 2 intercepts and then 2 over --> 4/2 = 2
These are both positive but 4 does not equal 2
a.) We have just proved that they have different slopes now we must determine if they have the same b. Because we know the slope of Function A we can simply move backward to get to x=0
When X=0 y= 3-4 = -1 And because in Function B we can clearly see the b at y=4 this is false.
Hope this helps and makes you have an Awesome Day!

perpendicular to y=3x-2
The key to understand this problem is that perpendicular lines have slopes that are the negative reciprocals of each other. Example, a line with slope 3/4 has a perpendicular with a slope of -4/3. So flip it over and take the negative. Like 7/12 and -12/7 or 2 and -1/2 (because 2 = 2/1)
The slope of y = 3x - 2 is 3 (the number preceding the "x' if the line is in the form y = mx + b)
So the line perpendicular to y = 3x - 2 has a slope of -1/3.
So now you just need to write the equation of the line with slope -1/3 that goes through (-9, 5). Use the point-slope form, y - y1 = m(x - x1) where (x1, y1) is (-9, 5) and m = -1/3
y - 5 = -1/3(x - -9)
y - 5 = -1/3(x + 9)
That's the answer. If they want you to give the answer in the y= mx + b format (slope-intercept) then multiply it out and combine like terms.
y - 5 = -1/3(x + 9)
y - 5 = -1/3x - 3
y = -1/3x + 2

Answer:
41910.
Step-by-step explanation:
We can calculate this by first finding the sum for k = 1 to 50 then subtracting the sum for k = 1 to 14.
We use the formula (1/6)n(n+1)(2n+1)
So for 1 to 50 its 1/6 * 50* 51 * 101 = 42925
and for 1 to 14 it comes to 1/6*14*15*29 = 1015
So the answer is 41910.

The sides forming the right angles and hypotenuse of a right angled triangle are x cm, (2x + 2) cm and (3x – 2) cm respectively. Calculate the perimeter of the triangle.
Answer:
6x
Step-by-step explanation:
Perimeter is the sum of all the sides:
(x) + (2x + 2) + (3x - 2)
Add like-terms:
6x + 2 - 2 = 6x
Perimeter = 6x
Help me please I’m bad at slopes
a Members of a soccer team raised $1530.50 to go to a tournament. They rented a bus for $1164.50 and budgeted $30.50 per player for meals. Write and solve an equation which can be used to determine x, the number of players the team can bring to the tournament.
The number of players that can be taken to the tournament is 12 players.
The equation that can be used to represent the total amount spent by the soccer team is:
Total amount spent = cost of rented bus + (cost per meal x total number of players)
$1530.50 = $1164.50 + $30.50x
Where: x = total number of player
In order to determine the value of x, the following steps would be taken:
Combine similar terms
$1530.50 - $1164.50 = $30.50x
$366 = $30.50x
Divide both sides of the equation by 30.50
x = $366 / $30.50
x = 12 players
