Find the value of A in each cases:
- cosA=√3/2
Answer:
A = [tex]\frac{5\pi }{6}[/tex]
Step-by-step explanation:
Given that Cos A = [tex]-\frac{\sqrt{3} }{2}[/tex]
cos A = [tex]cos (\pi -\frac{\pi }{6} )[/tex]
A = [tex]\pi - \frac{\pi }{6}[/tex]
A = [tex]\frac{5\pi }{6}[/tex]

Step-by-step explanation:
Use the given similar triangles to find the value of x
I need the answer fast please!!
Answer:
I believe the answer is x=7
Step-by-step explanation:
3x and 4x-1 are corresponding sides and so are 14 and 18.
You cross multiply with the smaller triangle lengths at the top.
3x/(4x-1)= 14/18
Cross multiply to get
18(3x)= 14(4x-1)
54x=56x-14
Subtract 54x on the other side and add 14 to the other (or subtract 56x to the other side)
you get 14=2x and divide 14 by 2 to get x=7
Details: Cargo ship can carry 21,600 tons Cars weigh 3.6 tons each Trucks weigh 7.5 tons each y = number of cars x= number of trucks Your equation was 3.6y + 7.5x = 21600 Find the number of trucks that can be shipped if there are no cars.
Given:
The equation is
[tex]3.6y+7.5x=21600[/tex]
where, y is the number of cars and x is the number of trucks shipped.
To find:
The number of trucks that can be shipped if there are no cars.
Solution:
We have,
[tex]3.6y+7.5x=21600[/tex]
If there are no cars in the cargo ship, then y = 0 because y is the number of cars.
Putting y=0 in the given equation, we get
[tex]3.6(0)+7.5x=21600[/tex]
[tex]0+7.5x=21600[/tex]
[tex]7.5x=21600[/tex]
Divide both sides by 7.5.
[tex]x=\dfrac{21600}{7.5}[/tex]
[tex]x=2880[/tex]
x is the number of trucks shipped.
Therefore, the number of trucks that can be shipped if there are no cars is 2880.

A new car is purchased for $32,500. The car depreciates every year ata
rate of 14%. Write an exponential function that represents that situation
Answer:
[tex]y=32500(0.86)^{x}[/tex]
Step-by-step explanation:
General exponentially depreciating function is given as
[tex]y= a(1-b)^{x}[/tex]------------(1)
Where a is initial value, b is percent depreciation/unit time and x is time
Here
[tex]a=32,500 \ \ \ b=0.14 \ \ \ and \ \ x \ is \ time \ in \ years[/tex]
Substituting above values in equation (1)
[tex]y=32500(0.86)^{x}[/tex]
At x=0
[tex]y=32500(0.86)^{0}\\y=32500[/tex]
At x=1
[tex]y=32500(0.86)^{1} \\y=27950[/tex]
The cafeteria can serve 32 lunches in 5 minutes. How long will it take them to serve 57 lunches?

Shonda has $125. She spends 35% of the money she has on a concert ticket. How much did Shonda spend on the ticket?
Answer:
she spent $43.75
Step-by-step explanation:
you basically need 35% of $125
cool trick with this is "of" always means multiplication
35% x 125= 43.75
she spent $43.75
Shonda spent the amount of $43.75 on the concert ticket.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
To find out how much Shonda spent on the concert ticket, we can use the following proportion:
(35%) × 125 = x/1
where x is the amount of money spent on the concert ticket, and we know that 35/100 (or 0.35) is 35% of 125.
Convert percent into decimal form and solve for x:
(0.35) × 125 = x
Apply the multiplication operation, and we get
x = 43.475
Therefore, she spent $43.75 on the concert ticket.

Which expression is equivalent to the given expression?
(-6ab)2
Answer:
B. 36a^2b^2
Step-by-step explanation:
1. Apply exponent rule: (-a)^n = a^n, if n is even
(-6ab)^2 = (6ab)^2
(6ab)^2
2. Apply exponent rule: (a × b)^n = a^nb^n
(6ab)^2 = 6^2a^2b^2
6^2a^2b^2
3. 6^2 = 36
36a^2b^2
In other words, your answer is B.
The answer is Option B)

Answer:
x = 18
m<A = 166°
Step-by-step explanation:
The parallel lines are cut by a transversal, so corresponding angles A and B are congruent.
7x + 40 = 3x + 112
4x = 72
x = 18
m<A = 7x + 40 = 7(18) + 40 = 126 + 40 = 166
7x+40 = 3x+112
x=18
7(18)+40

Given:
The triangle PQR on a coordinate plane.
To find:
The image of point Q after a rotation of 90° counterclockwise about the origin.
Solution:
From the given graph, it is clear that the coordinates of point Q are (5,0).
If the figure is rotated 90° counterclockwise about the origin, then the rule of rotation is defined as
[tex](x,y)\to (-y,x)[/tex]
Using this rule, we get
[tex]Q(5,0)\to Q'(-(0),5)[/tex]
[tex]Q(5,0)\to Q'(0,5)[/tex]
So, the image of point Q is (0,5).
Therefore, the correct option is (a).
