Find the value of "x". ​

Answers

Answer:

x = 4.52984

Step-by-step explanation:

Since the triangle has a right angle you need to use the the trigonometric function cos (theta which is the angle given that isn't 90°) = adjacent / hypotenuse (adjacent is the side close to the angle you're using which is 22° and the hypotenuse is the longest side of the triangle that is in the away from the right angle)

From there you plug in the numbers which now become cos (22°) = 4.2 / x

Then you isolate the x by multiplying it to both sides so it's on the left and divide both sides by cos (22°) which will end you up x = 4.2 / cos (22°)

Then you just divide and you 4.52984

after eating at a restaurant the bill for your table is $62.50. There is a 6% sales tax and you want to leave a tip for 18% based on the pre-tax amount. How much money do you need to cover your final bill?

Answers

Answer:

Step-by-step explanation:

Your bill is $62.50

$62.50 * .06 = $3.75 (this is your sales tax added)

So your total is up to: $66.25

Adding the tip the same way using $66.25 *.18 = $11.93

Tip would be $11.93

Total coming to: $78.17

hope this helps

Answer:

$77.50

Step-by-step explanation:

Tax:

62.50x0.06= 3.75

3.75+62.50= 66.25

Tip:

62.50x0.18= 11.25

Question: (help please?!?!)Bridget has $2,835 in her savings account. Each pay period, $945 is deposited into

her savings account. If her paycheck deposits are the only transactions, which of the

following equations could be used to find y, the amount in her savings account based

on x, the number of times she is paid?

A y = 2,835 - 945x

B 2,835y = 945x

C y = 945x + 2,835

D y = 2,835x + 945

Answers

Answer:

C. y = 945x + 2,835

Step-by-step explanation:

Each pay period 945 dollars is deposited so that's the slope, which x stands for each pay period. She already started with 2,835 in her savings account so that is the y-intercept.

Slope: 945x

Y- intercept: 2,835

Therefore,

equation: y = 945x + 2,835

Quadrilateral ABCD undergoes a reflection across the x-axis to form quadrilateral a b c d the coordinates of a r the reflected quadrilateral a b c d is then translated three units to the right and third and two units up to form quadrilateral a quotation b quotation quotation see quotation

Answers

Solution :

From the figure,

The coordinates of --

A = (-5,-3)

B = (-6,-1)

C = (-3,-1)  

D = (-2,-3)

When it undergoes reflection about x-axis, we have the coordinates of the quadrilateral as

A' = (-5,+3)

B' = (-6,+1)

C' = (-3,+1)

D' = (-2,+3)

Now A'B'C'D' is translated 3 units to right, so the coordinates will be --

A" = (-2,3)

B" = (-3,1)

C" = (0,1)

D" = (1,3)

When the quadrilateral moves third and two units up, we get

A"' = (3,3)

B"' = (2,1)

C"' = (5,1)

D"' = (6,3)
