Answer:

Step-by-step explanation:

The probability of drawing a red card is 1/2, since half of the cards in a deck are red. The probability of drawing an ace from a deck is 1/13, since there is an equal chance to pick any of the 13 numbers.

P(red card and ace)= P(red card)*P(ace)=1/2 * 1/13=1/26

Jason is building a 1 : 180 scale model of a real castle. his model has a rectangular base that is 3 feet wide and 4 feet long.w
balu736 [363]
The area of the actual castle would be 388,800 sq. ft.

We would multiply each of the sides of the scale model both by 180 to find the side lengths of the actual castle.

So...
180 x 4 = 720
180 x 3 = 540

If Area is equal to Length Times Width, all thats left to do is to multiply the two sides together.

720 x 540 = 388,800

Hope this helped! :D

Jimmy is planning his birthday party! He spent $35 on balloons and chocolate cake. He bought balloons that cost $0.25 each and a
emmainna [20.7K]

In the equation, x represents the number of balloons. We say that 25 cents per balloon becomes 0.25x.

Jimmy also purchased a chocolate cake. This is the PLUS sign in the equation.

The total for everything purchased is $35.

Balloons x at 25 cents each = 0.25x plus a chocolate cake for $10 together equals $35.
