Since the side which measures 10 is a vertical projection of the hipotenuse x on a 20 degree angle:

10 = x*sin(20°)

x = 29.238044

Since we have to round to the nearest hundreth:

x = 29.24 m

sin 20° ≈ 0.34                                                        opposite  leg
                                                     Note : sin x° = ---------------------
sin 20° = 10/x                                                         hypotenuse

x ≈ 10/0.34

x ≈ 29.41

A box contains four equal sized cards labeled 1, 3,5, and 7. Tim will select one card from the bow. What is the probability that
Zielflug [23.3K]

Answer: The probability is zero.

Step-by-step explanation:

The labels on the 4 cards are 1, 3, 5 and 7. Because the cards are equal, the probability of dragging at random each one of them is equal to 1/4 = 0.25.

Now, the probability that Tim selects a card labeled with a 4 is equal to the number of cards labeled with a 4, divided the total number of cards.

We do not have cards labeled with a 4, so the probability is:

p = 0/4 = 0

because we do not have any card labeled with a 4, the probability of selecting one at random is equal to zero.

I have absolutely no idea what’s going on
MA_775_DIABLO [31]

Answer:

The hypotenuse( longer side) of the triangle = c^{2} = a^{2} +b^{2} \\Therfore, c = \sqrt a^{2} +b{2}\\ \\

Step-by-step explanation:

Here, side =c

Therfore, area = c *c

That is a^{2} +b{2} = 50^{2} + 35^{2} = 3250 = 57 units sq

Felipe is planning a party. He has $50.00 to spend on sandwiches that cost $2.50 per person, $25.00 to spend on drinks that cost
Doss [256]
It would be b. In all, he has $100 to spend since $50+$25+$25=$100. We have x people coming and he has to spend $2.50, $1.50, and $3.00 per person, respectively. The phrase "per person" indicates we must multiply, so we have to multiply each value by "x." To find out how much money he has left, we must subtract. All of this put together is 100-(2.50x+1.50x+3.00x). Add the like terms and you get 7x. Your final expression would be 100-7x, which is answer choice b.

Write an equation for the parabola whose vertex is at (4, 9) and which passes through (5, 24).
babunello [35]
The general formula to form a parabole equation is written below.
y = a(x - h)² + k
with (x,y) is one of the points lies on the parabola, and (h,k) is the vertex of the parabola.

From the question above, we get this information
(x,y) = (5,24)
(h,k) = (4,9)
The remaining value to find is a. We need to find the value of a to form the equation. Input the numbers to the equation.
y = a(x - h)² + k
24 = a(5 - 4)² + 9
24 = a(1) + 9
24 = a + 9
24 - 9 = a
a = 15

Write the equation, without inputing the value of x and y
y = a(x - h)² + k
y = 15(x - 4)² + 9
<em>This is the equation</em>
