Genevieve is 3 years older than twice her brother's age. Genevieve is 21 years old. Write an equation to find her brother's age.​

Answers

Answer 1
Her brother is 9.

Because she is 3 years older than half his age, subtract 3 - 21. This gives 18. Then divide 18 / 2. This gives 9.
Answer 2

The equation that represents Genevieve's brother is y = 18/2.

What is the equation that represents Genevieve's brother age?

The equation that represents Genevieve's age:

21 = 3 + 2Y

Where Y represents Genevieve's brother age

In order to determine the required equation, make y the subject of the formula

21 - 3 = 2y

18 = 2y

y = 18/2

A box contain 10 green pins 3 are blue and 7 are green. Two pins are randomly taken out of the box without replacement work out the probability that both pins are the same color

Answers

Answer:

[tex]P(Z)=\frac{8}{15}[/tex]

Step-by-step explanation:

From the question we are told that:

Sample size [tex]n=10[/tex]

Green pins [tex]x=7[/tex]

Blue pins [tex]y=3[/tex]

 

Generally the probability of getting two green is mathematically given by

[tex]P(2X)=\frac{7}{10}*\frac{6}{9}[/tex]

[tex]P(2X)=\frac{7}{15}[/tex]

Generally the probability of getting two blue is mathematically given by

[tex]P(2Y)=\frac{3}{10}*\frac{2}{9}[/tex]

[tex]P(2Y)=\frac{1}{15}[/tex]

Therefore the probability that both pins are the same color P(Z)

[tex]P(Z)=P(2Y)+P(2X)\\P(Z)=\frac{7}{15}+\frac{1}{15}[/tex]

[tex]P(Z)=\frac{8}{15}[/tex]

Eric and pam are paid ​$48.75 for their work. Eric worked 2.5 ​hours, and pam worked 4 hours. They split the money according to the amount of time each of them worked. How much is erics​'s share of the​ money? Explain.

Answers

Answer:

$18.75

Step-by-step explanation:

Determine the total hours worked by both individuals = 2.5 + 4 = 6.5 hours

Determine the fraction of hours that Eric worked = 2.5/6.5 = 0.384615

Multiply this fraction by the total amount earned = 0.384615 x $48.75 = $18.75

Pepe compró una caja de chocolates en $5.950, incluido el 19% de IVA. ¿Cuál es el precio de la caja de chocolates sin el IVA?

Answers

Answer:

$4819.5

Step-by-step explanation:

Pepe bought a box of chocolates for $ 5,950, including 19% VAT. What is the price of the box of chocolates without VAT?

The price of chocolates = $5,950

VAT = 19%

We need to find the price of the box of chocolates without VAT.

VAT is applied on the Cost price of the object.

Price = $5,950 - 19% of $5,950

[tex]=5950- 5950\times \dfrac{19}{100}\\\\=\$4819.5[/tex]

So, the price of the box without VAT is equal to $4819.5.

c. square.
d.trapizoid

Answers

Answer:

c. square.

Step-by-step explanation:

squares have 4 parallel sides so if you cut it in half you will still be parallel

The 2D figure formed by slicing parallel to the base of a triangular prism is option B. Triangle.

What is a Triangular Prism?

Triangular prism is the three dimensional figure which consists of two triangular shaped bases and three rectangular lateral faces.

WE have to find the 2d figure formed by slicing parallel to the base of a triangular prism.

We know that base of a triangular prism is triangle.

So, when we slice a parallel plane to the base of the triangular prism, the resulting 2D shape will also be a triangle.

Hence the 2D shape formed by slicing parallel to the base of a triangular prism is triangle.
