Answer:

13/102

Step-by-step explanation:

In a standard deck of 52 cards, there are 13 black spades, 13 black clubs, 13 red diamonds and 13 red hearts. There are 26 black cards in the deck of 52 cards.

Probability of drawing a black card = 26/52 = 1/2

Suppose we drew the black card. There are now only 51 cards left in the deck. ALL of the hearts are still there - 13 of them.

Probability of drawing a heart from this deck of 51  = 13/51

In general, for the probability of event A and then event B, we multiply.

1/2 x 13/51 = 13/102

Answer:

This question needs to be written better

Step-by-step explanation:

Each math symbol has words that direct u to know how/when to use them

For example:

Find the sum of 70 and 83

+- (Addition)-(Words used to say addition: Add, Sum , Plus, Increase, Total)

83+70=153

Find the difference between 83 and 70

_-(Subtraction),(Words used to say subtraction: Minus, Less, Difference, Decrease, Take Away, Deduct)

83-70=13

How many times can 2 go into 12?

÷-(Divide/Division)-(Words that are used to say Divide/Division: Quotient, Goes Into, etc.)

12÷2=6

Find the product of 6 and 7

×-(Multiplication/Multiply)-(Words that are used to say Multiplication/Multiply: Product, By, Times, Lots Of)

6×7=7

Hope this helps!

Answer:

8%

Step-by-step explanation:

For simple interest, we use the equation I = PRT, where I is the interest earned, P is the principal/amount invested, R is the rate as a decimal, not percentage, and T is the time in years.

For this problem, we have to use 0.5 for T, because 6 months is 1/2 a year.

20 = (500)(r)(0.5)

20 = 250r

r = 0.08 = 8%

Answer:

5 faces, 8 edges, 5 vertices

Given:

The rate of interest on three accounts are 7%, 8%, 9%.

She has twice as much money invested at 8% as she does in 7%.

She has three times as much at 9% as she has at 7%.

Total interest for the year is $150.

To find:

Amount invested on each rate.

Solution:

Suppose x be the amount invested at 7%. Then,

The amount invested at 8% = 2x

The amount invested at 9% = 3x

Total interest for the year is $150.

[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]

Multiplying both sides by 100, we get

[tex]7x+16x+27x=15000[/tex]

[tex]50x=15000[/tex]

Dividing both sides by 50, we get

[tex]x=\dfrac{15000}{50}[/tex]

[tex]x=300[/tex]

So, the amount invested at 7% is [tex]300[/tex].

The amount invested at 8% is

[tex]2(300)=600[/tex]

The amount invested at 9% is

[tex]3(300)=900[/tex]

Hence, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

Step-by-step explanation:

Do the steps that I did on Problem A for each!!!!

A:-3(4-3p)

a=-3, b=4, c=3p

Apply the distributive law:

[tex]-3*4-(-3)*3p[/tex]

Add minus - plus rules:

[tex]-3*4+3*3p[/tex]

Simplify:

=[tex]-12+9p[/tex]

B:-3(7-6u)

a=-3, b=7, c=6u

=-3*7+3*6u

Simplify;

=[tex]-21+18u[/tex]

C:-6(-1+2c)

a=-6, b=-1, c=2c

=-6(-1)+(-6)*2c

=6*1-6*2c

Simplify:

=[tex]6-12c[/tex]

D:6(-n+7)

a=6,b=-n,c=7

=6(-n)+6*7

=-6n+6*7

Simplify:

=--6n+42

E;9(5+3c)

a=9,b=5,c=3c

=9*5+9*3c

Simplify:

=45+27c

Answer:

Conmutativa

Step-by-step explanation:

Propiedad conmutativa : El orden de los factores no varía el producto o la suma. Un ejemplo seria 3 x 10 da lo mismo que 10 x 3 que es 30.

Con la suma 3+ 5 es lo mismo que 5+3 que es 8.

Nada mas funciona con SUMA o MULTIPLICACION. Nunca en la resta.

This is your answer ☺️. If I'm right so,

Please mark me as brainliest. thanks!!!

Step-by-step explanation:

20°+120°+I°=180°

I=40°

using sine rule,

I/sin I=x/sinX

12/sin40=x/sin20

x=12sin20/sin40

x=6.4

using similarly and enlargement,

we have, cw/cp=y/120

8/12=y/120

y=80°

Answer:

35 are boys and other are girl

Answer: 35 boys

Step-by-step explanation:

So we know the ratio of girls to boys for every 10 student is 3 girls to 7 boys from there we can multiply each number by 5 to give us a total of 50 students which would be 15 girls to 35 boys.

Let that particular no. be x

x=18+5

x=23

Answer:

33

Step-by-step explanation:

let the number be n , then the number divided by 3 is [tex]\frac{n}{3}[/tex] and decreased by 5

[tex]\frac{n}{3}[/tex] - 5 = 6 ( add 5 to both sides )

[tex]\frac{n}{3}[/tex] = 11 ( multiply both sides by 3 )

n = 33

The number is 33

Step-by-step explanation:

Answer:

5x+2y=15

y=-3x+4

Substituting the value of y in the first equation..

5x+2(-3x+4)=15

5x-6x+8=15

x = -7

So, y = -3(-7)+4

y = 25

Answer:

[tex]x = - \frac{11}{7} [/tex]

Step-by-step explanation:

1) Break down the problem into these 2 equations.

[tex]x - 1 = 6x + 12[/tex]

[tex] - (x - 1) = 6x + 12[/tex]

2) Solve the first equation. x - 1 = 6x + 12

[tex]x = - \frac{13}{5} [/tex]

3) Solve the second equation: -( x - 1 ) = 6x + 12.

[tex]x = - \frac{11}{7} [/tex]

4) Collect all solution.

[tex]x = - \frac{13}{5}. - \frac{11}{7} [/tex]

5) Check solution.

When x=-\frac{13}{5}x=−513, the original equation |x-1|=6x+12∣x−1∣=6x+12 does not hold true.

When x=-\frac{13}{5}x=−513, the original equation |x-1|=6x+12∣x−1∣=6x+12 does not hold true.We will drop x=-\frac{13}{5}x=−513 from the solution set.

6) Simplify.

[tex]x = - \frac{11}{7} [/tex]

Therefor, the answer is x = - 11/7.
