Answer:
a = 3.46 , c = 9.9
Step-by-step explanation:
These are the following identities:
[tex]sinx=\frac{perpendicular}{hypotenuse} \\\\cosx=\frac{base}{hypotenuse}\\\\tanx=\frac{perpendicular}{base}\\[/tex]
Easier way to learn this is
Some people have curly brown hair till painted black
Sinx = per/hyp cosx = base/hyp tanx = per/base
So if use the angle 60° we can see that the opposite side(perpendicular) to the angle is 6 and the base side is a so we need the identity which uses the opposite side(perpendicular side) and the base side and not the hypotenuse so that is tan x so,
[tex]tan\ 60=\frac{6}{a} \\\\1.732=\frac{6}{a}\\\\1.732a=6\\a=\frac{6}{1.732}\\\\a=3.46\\[/tex]
So a = 3.46
Now to calculate c:
If we take the angle 45° and see the opposite side(perpendicular side) is 7 and the hypotenuse is c so need the identity which uses the opposite side(perpendicular side) and the hypotenuse and not the base, which is sin x so,
[tex]sin 45=\frac{7}{c}\\\\0.707=\frac{7}{c}\\\\0.707c=7\\\\c=\frac{7}{0.707}\\\\c =9.9\\[/tex]
so c = 9.9

Find the PERCENT of Change.
The original cost was $50 and the new cost is $200.
Answers
75%
explanation:
Answer:
300%
Step-by-step explanation:
To find percent change we need to use this formula:
[tex]change = \frac{Amount of change}{Original} * 100[/tex]
To find the amount of change we need to minus 50 from 200:
200 - 50 = 150
Now that we have the amount of change we can plug it in to the equation with the original amount (50):
[tex]change = \frac{150}{50} = 3 * 100 = 300[/tex]
Therefore, the percent of change is 300%.

Step-by-step explanation:
2x-10=10
2x=20
x=10
Answer:
x=10
Step-by-step explanation:
2(x - 5) = 10
You would first multiply 2 by x and 5
2x-10 = 10
then you would add ten to both sides
2= 20
then you would divide 2 by 20
x=10

(3,4);m=-z in point slope formula
Answers
Given:
Point = (3,4)
Slope : m = -z
To find:
The point slope formula.
Solution:
Point slope form: If a line passes through the point [tex](x_1,y_1)[/tex] and having slope m, then the point slope form of the line is
[tex]y-y_1=m(x-x_1)[/tex]
The line passing through the point (3,4) and having slope -z.
Putting [tex]x_1=3,y_1=4, m=-z[/tex], we get
[tex]y-4=-z(x-3)[/tex]
Therefore, the required point slope form is [tex]y-4=-z(x-3)[/tex].

What is the fifth term of the geometric sequence whose first three terms are 486, 162, and 54?
a. 2
b. 3
c. 4.5
d. 6
e. 9
Answers
Answer:
6
Step-by-step explanation:
an = ar^(n-1)
a = first term
n = nth term
r = common ratio
r = r2 / r1 = r3 / r2
The first 3 terms are :
486, 162, and 54
Hence,
a = 486
r = 162 / 486 = 1/3
Hence ;
a5 = 486(1/3)^5 - 1
a5 = 486(1/3)^4
a5 = 486(1 / 81)
a5 = 486 * 1 / 81
a5 = 486 / 81
a5 = 6
The 5th term of the geometric progression will be ; 6

Answers

(2,4)
(3,3)
(4,2)
Step-by-step explanation:
To solve this table first convert the equation to slope-intercept form (y=mx+b), to do this solve for y in the equation. The slope-intercept form is y=-x+6, where -1 is the slope and 6 is the y-intercept. Then from that, you can get your first point, because you know the y-intercept is 6, therefore when x equals 0 y must be 6. Next, because the slope is -1 that means the y-value decreases by 1 every time the x-value increases by 1. So to find the rest of the y-values simply subtract 1 from the previous y-value.

Answer: C
Step-by-step explanation:
1.25 + (- 0.75) is equal to 1.25 - 0.75.
1.25 is positive while - 0.75 is negative. So 1.25 is head toward the right while - 0.75 is head toward the left.
And when you substract them, you will get 0.5.
So the answer is C.
Luke went to a blackjack table at the casino. At the table, the dealer has just shuffled a standard deck of 52 cards.
Luke has had good luck at blackjack in the past, and he actually got three blackjacks with Queens in a row the last time he played. Because of this lucky run, Luke thinks that Queens are the luckiest card.
The dealer deals the first card to him. In a split second, he can see that it is a face card, but he is unsure if it is a Queen.
What is the probability of the card being a Queen, given that it is a face card? Answer choices are in a percentage format, rounded to the nearest whole number.
a) 8%
b) 4%
c) 33%
d) 77%
Answers
Answer:
c) 33%
Step-by-step explanation:
In a standard deck of cards, there are 52 cards total and of those 52, there are 12 face cards. One-third of those face cards are queens, (because there are 4 queens in a deck of cards, and [tex]\frac{4}{12}=\frac{1}{3}[/tex]). Therefore, there is a 33% chance that the card Luke holds is a queen.

33%

He would drive 536 miles in 5 hours
Step-by-step explanation:
First set up your equation:
804 = 12x
Divide 804 by 12 and get 67 = x
Since per one hour you drive 67 miles, multiply 67 by 8 and get 536.
So, he drives 536 miles in 5 hours
Answer: I think 402
Step-by-step explanation: I divided 804 to 4 and I got 201 then I added 201+201= 402 and each 4 hours he went 201 miles so if you add 201 and 201 you get 402 miles. Hope it helped!! :)

At the neighborhood grocery, 55 pounds of steak cost \$20.60$20.60. How much would it cost to buy 44 pounds of steak?
Answers
Answer:
$16.48
Step-by-step explanation:
Create a proportion where x is the cost of 44 pounds of steak:
[tex]\frac{55}{20.60}[/tex] = [tex]\frac{44}{x}[/tex]
Cross multiply and solve for x:
55x = 906.4
x = 16.48
So, the cost of 44 pounds of steak is $16.48
