Answer: x = 30' , y = 45'

hope this helps

Step-by-step explanation:

U is 90' it's a right triangle

well simple VRT you already know 2 angles which is 60' and 90'

R = 60'

V = 90'

T = x

you know that a triangle = 180'

so you do

180 - 60 - 90 = x

30 = x

if you want to do y

then you already know that U is 90' on both sides.

since you also know S,

S = 45'

U = 90'

V = y

180 - 90 - 45 = y

45 = y

A large pizza has a diameter of 35cm. 2 large pizzas cost $19.99 A medium pizza has a diameter of 30cm. 3 medium pizzas cost $24
insens350 [35]
So first we need to find the area of both using a=3.14*radius*radius

to find the radius we need to divide 35 by 2 (large) and 30 by 2 (medium)

lets do the large first since the raidus is 17.5 we put it into a=3.14*17.5*17.5

and then we get 961.63, for the medium we do a=3.14*15*15 which is 706.50

now for the large 961.63 * 2 is 1923.26 and the price is 19.99 

for the medium we do 706.50 *  3 which is 2119.5 and costs 24.99

So the medium pizzas are a better deal

Please help asap i do not like slopes
vlabodo [156]

Your answer is A. (0,0)

The equation of the line is in the form y = mx + b, where m is the slope and b is the y-intercept, which is where the line cuts the y-axis.

In the line y = 4x, the ‘m’ would be 4 and the ‘+ b’ would be 0, which means that the line cuts the y-axis when y = 0.

There are only 2 answer options that have y = 0, A (0, 0) and D (4, 0). To find out which is correct, we can substitute in y = 0 into the equation y = 4x to see what the x-value would be:

y = 4x

0 = 4x

0 = x

Therefore the answer is A.

I hope this helps!

A jar contains two blue and five green marbles. A marble is drawn at random and then replaced. A second marble drawn at random.
DerKrebs [107]

corrected question:A jar contains two blue and five green marbles. A marble is drawn at random and then replaced. A second marble drawn at random. For each of the following, find the probability that: a) both marbles are blue b) both marbles are the same color  c)the marbles are different in color

Answer:

Step-by-step explanation:

<u><em>The probability was done with replacement.</em></u>

Probaility of an event happening=\frac{number of required outcomes}{number of possible outcomes}

number of blue marbles= 2

number of green marbles=5

total number of marbles=7

(a) probability that both marbles are blue = pr(first is blue)*pr(second is blue)

                                  =\frac{2}{7}*\frac{2}{7}

                                   =\frac{4}{49}

(b)probability that both marbles are the same color =pr(first is blue)*pr(second is blue) + Pr(first is green)*Pr(second is green)

   =\frac{4}{49} + \frac{5}{7}*\frac{5}{7}

   =\frac{4}{49} + \frac{25}{49}

 =\frac{29}{49}

(c)Probability that the marbles are different in colors=pr(first is blue)*pr(second is green) + Pr(first is green)*Pr(second is blue)

  =\frac{2}{7}*\frac{5}{7}+ \frac{5}{7}*\frac{2}{7}

           =\frac{10}{49}+\frac{10}{49}

      =\frac{20}{49}
