If you have a standard 52 card deck, there are 13 hearts and 4 10’s. Since one of the tens will be a heart, we can total this counts as 16 cards in the deck. Do 16 divided by 52 and there is your answer which is 31%. You have a 25% chance of choosing a hearts card in a deck and 8% chance of choosing a 10.

BCD= 120 degrees. explanation: the 4 angles of a parallelogram must equal 360 degrees. so you add all 4 angles & get 6x. you then take that 6 & divide it from 360 (360/6) and get 60. therefore x=60. so then you just multiple BCD (2x) by 60 and you get 120 degrees

Let g be the function given by g(x)=-3x^2-2x+3 evaluate g(-2)

sashaice [31]

g(x) = -3x² - 2x + 3

g(-2) = -3(-2)² - 2(-2) + 3

g(-2) = -12 + 4 + 3 = -5

Simplify 3/4(1/2×-12)+4/5

Wittaler [7]

Answer: $\frac{3}{8}x-\frac{41}{5}$ or $\frac{3}{8}x-8\ \frac{1}{5}$

Step-by-step explanation:

Given the following expression:

$\frac{3}{4}(\frac{1}{2}x-12)+\frac{4}{5}$

You can follow these steps in order to simplify it:

1. You need to apply Distributive property:

$=\frac{3}{8}x-9+\frac{4}{5}$

2. And now you must add the like terms. Then:

$=\frac{3}{8}x-\frac{41}{5}$

Therefore you get the following answer:

$\frac{3}{8}x-\frac{41}{5}$ or $\frac{3}{8}x-8\ \frac{1}{5}$

Lucas' mom is eight years older than twice his age. The sum of their ages is 77. How old are Lucas and his mom?

Rudiy27

Answer:

Age of Lucas = 23 years

Age of Lucas Mom = 54 Years

Step-by-step explanation:

In this question we have to find the age of Lucas and his Mom

Let the age of Lucas be x

According to given condition

Twice of his age 2 * x =2x

Eight years older means age + 8x

Age of his mom = Twice of his age + 8

= 2x + 8 .................(ii)

now according to second condition

Age of Lucas + Age of his mom = 77

Put the values in the condition above

x + (2x + 8) = 77

x + 2x + 8 =77

3x + 8 = 77

subtracting 8 from both sides

3x + 8 - 8 = 77 -8

3x = 69

Dividing both sides by 3

x = 69 / 3

x = 23 years

Age of Lucas = 23 years

Now from equation (i)

Age of Lucas Mom = 2(x) + 8

putting in the value we get

Age of Lucas Mom = 2 ( 23) + 8

=46 + 8

=54 Years

Age of Lucas Mom = 54 Years
