Step-by-step explanation:

Area of a circle formula: $A = \pi r^{2}$

given:

- diameter = 14m

- pi = 22/7

$radius (r) = diameter/2 = 14/2 = 7\\A = 22/7*(7)^2\\A = 22/7*(49)\\A = 154$

Juan was given a gift card for a coffee shop. Each morning, Juan uses the card to buy one cup of coffee. Each cup of coffee cost

Black_prince [1.1K]

Answer:

$A=30-2x$

Step-by-step explanation:

Cost of one cup of coffee=$2

The original amount of money on the gift card= $30

Juan's expenses in buying coffee, after $x$ morning are $\$2\times x$ .

The amount of money left, $A$ , on the card $=$ (Original amount) $-$ (Total expenses)

$A=30-2x$

Hence, the equation for, $A$ , the amount of money remaining on the card is

$A=30-2x.$

Given the two sets, what is A ∩ B ? A = {1, 2, 3, 4, 5, 6} B = {2, 3, 5, 7}

topjm [15]

Answer:

2, 3, 5

Step-by-step explanation:

A∩B means "A intersection B" which includes all elements that are shared in BOTH sets. This would be the middle crossover section of a Venn diagram.

Hence, 2 and 3 and 5 are shared in both sets.

A bag contains 25 marbles;10 black,13 red,and 2 blue. A marble is drawn from the bag at random.

Deffense [45]

For the answer to the question above asking to explain why the events "getting a black marble" and "getting a red marble" are mutually exclusive.
A marble can have only one color, so you cannot choose a marble that is both black and red. Therefore the events are mutually exclusive (cannot happen simultaneously)
