Answer:

B) 11.8

Step-by-step explanation:

First write in 4 for x and 2 for y

Then multiply 1.3 times 6 (4+2) and subtract 2-6

Your expression should now be 7.8 +4

After adding these, it should be 11.8

You are ordering pizzas for a birthday party and getting them delivered to your house. You order 12 pepperoni pizzas, 8 cheese p

krok68 [10]

Let

x-------> the cost of each pepperoni pizza

y-------> the cost of each cheese pizza

z-------> the cost of each Hawaiian pizza

we know that

$12x+8y+4z+5.50=184.54$ ------> equation A

$y=x$ -----> equation B

$z=x$ -----> equation C

Substitute equation B and equation C in equation A

$12x+8x+4x+5.50=184.54$

solve for x

$24x=184.54-5.50$

$x=179/24$

$x=\$7.46$

therefore

<u>the answer is</u>

$\$7.46$

Thales, an ancient Greek mathematician and philosopher, used certain triangles to find the height of unknown objects. He waited

Evgen [1.6K]

He was using an isosceles right triangle.

Both legs of an isosceles triangle are the same length, so knowing that when the shadow of the triangle was the same height as the triangle, then he knew that the shadow of an object would also be the same as it's height.

NO LINKS! Please help me with this problem.

Vedmedyk [2.9K]

$\\ \rm\Rrightarrow \dfrac{WX}{UV}=\dfrac{HI}{FE}$

$\\ \rm\Rrightarrow \dfrac{WX}{16}=\dfrac{10}{8}$

$\\ \rm\Rrightarrow WX/2=10$

$\\ \rm\Rrightarrow WX=20$

Again

$\\ \rm\Rrightarrow \dfrac{WX}{UT}=\dfrac{HI}{FG}$

$\\ \rm\Rrightarrow \dfrac{20}{20}=\dfrac{10}{FG}$

$\\ \rm\Rrightarrow FG=10$

Visa Card USA studied how frequently young consumers, ages 18 to 24, use plastic (debit and credit) cards in making purchases (A

umka2103 [35]

Answer:

Given the consumer is 18 to 24 years old, there is 37% probability that he uses a plastic card.

Step-by-step explanation:

This can be formulated as the following problem:

What is the probability of B happening, knowing that A has happened.

It can be calculated by the following formula

$P = \frac{P(B).P(A/B)}{P(A)}$

Where P(B) is the probability of B happening, P(A/B) is the probability of A happening knowing that B happened and P(A) is the probability of A happening.

In this problem, we have:

What is the probability of the consumer using a plastic card, given that the consumer is 18 to 24 years old.

The problem states that the probability that a consumer uses a plastic card when making a purchase is .37, so $P(B) = 0.37$

P(A/B) is the probability that the consumer being 18 to 24 years old, given that he uses a plastic card. The problem states that this probability is .19. So $P(A/B) = 0.19$

P(A) is the probability that the consumer is 18 to 24 years old. There is a .81 probability that the consumer is more than 24 years old. So there is a .19 probability that he is 18 to 24 years old. So $P(A) = 0.19$

The probability is

$P = \frac{P(B).P(A/B)}{P(A)} = \frac{0.37*0.19}{0.19} = 0.37$

Given the consumer is 18 to 24 years old, there is 37% probability that he uses a plastic card.
