11x + 19y = –4
3x + 8y = –18

Answers

Answer 1

Answer:

Yes.

Step-by-step explanation:

(10, -6) are the values to substitute in for x and y, respectively.

11(10) + 19(-6) = 110 - 114 = - 14

3(10) + 8(-6) = 30 - 48 = -18

Mario's grape vine grows 7.5 inches in 3 weeks. At this rate, how much will the grape vine grow in 15
weeks?

Answers

Answer:

It will grow 37.5 inches

Step-by-step explanation:

It grew 7.5 in 3 weeks. Divide 7.5 by 3 and you'll get 2.5. So that means every week it grows 2.5 inches. So multiply 2.5 x 15 and you'll get 37.5 inches

It grew 7.5 in 3 weeks. Divide 7.5 by 3 and you'll get 2.5. So that means every week it grows 2.5 inches. So multiply 2.5 x 15 and you'll get 37.5 inches

Let f(x) = 1/x and g(x) = x²-
6x. What
two numbers are not in the domain of fºg?
Separate your answers with a comma.
Enter the correct answer.

Answers

Step-by-step explanation:

f°g=[tex]f(g(x))[/tex]

[tex]g(x)=x^2-6x[/tex]

[tex]f(x)=1/x[/tex]

[tex]f(g(x))=[/tex][tex]\frac{1}{x^2-6x}[/tex]

if the denominator is zero the number is undefined which makes it not in the domain of the function

set [tex]x^2-6x[/tex] equal to 0

the values for x is 0 or 6

so the only value that is not in the domain of f°g is 0 and 6

Hope that helps :)

What is the radius of a cylinder that has a volume of 500 ft ³ and that is 10 ft tall?

Answers

Answer:

The answer is 3.98942, rounded its 3.99.

Step-by-step explanation:

Answer:

3.99 ft

Step-by-step explanation:

Volume of a cylinder = πr²h

π = 3.14

volume = 500 ft³

height = 10 ft

πr²h = 500

3.14×r²×10 = 500

r² = 500/3.14×10

= 15.92..

= √15.92

r = 3.9899.. ≈ 3.99 ft

What is 562,148,900 in expanded form

Answers

Answer:

562,148,900 =

500,000,000

+ 60,000,000

+ 2,000,000

+ 100,000

+ 40,000

+ 8,000

+ 900

+ 0

+ 0

Answer:

Hello!

First we need to understand what expanded form is!

Expanded form is a way of writing a number to see the value of each digit. An example is:

111

100 + 10 + 1 = 111

So we must find the value of 562,148,900, in expanded form.

First we would find the first digit, and separate it from the other digits.

5

Then, we would count the digits behind that, and add it to the right of the five, in the form of zeroes.

500,000,000

We would continue this process for each digit, and then we would put them in addition form.

Your final answer would be,

 500,000,000  

60,000,000  +

2,000,000  +

100,000          +

40,000          +

8,000          +

900                  +

0                  +

0                  +

En una tienda de ropa vas a comprarte una pantalones que están de 150 a 90 euros y una camiseta de 40 a 24 ¿ tienen el mismo porcentaje de rebaja ?

Answers

Respuesta:

Sí, tienen el mismo descuento del 40%

Explicación paso a paso:

Dado :

PANTALÓN :

Precio inicial = 150

Precio con descuento = 90

Porcentaje de descuento en el precio:

(150 - 90) / 150 * 100%

60/150 * 100%

0,4 * 100

= 40%

CAMISA:

Precio inicial = 40

Precio con descuento = 24

Porcentaje de descuento en el precio:

(40-24) / 150 * 100%

16/40 * 100%

0,4 * 100

= 40%

Sí, tienen el mismo descuento del 40%

Od

Answers

Answer:

80 ft^2 of paint would be needed

Step-by-step explanation:

Since we do not consider the roof, all we need do is to calculate the area of the shape without the roof side

So without the roof, we have 4 rectangles

we have 4 ft by 4 ft on both sides

Then 6 ft by 4 ft on the other two sides

mathematically, the area of a rectangle is the product of its sides

so, we have the total area as;

2(6 * 4) + 2(4 * 4)

= 2(24) + 2(16)

= 48 + 32

= 80 ft^2

What is the probability of rolling a 20-sided number cube to a number that is prime or a multiple of 3?

Answers

Answer:

Probability of rolling a prime or multiple of 3 = 13/20

Probability of rolling a prime = 2/5

Probability of rolling a multiple of 3 = 3/10

Step-by-step explanation:

let's list primes and multiples of 3 from 1 to 20

Primes:

2 3 5 7 11 13 17 19

Multiples of 3:

3 6 9 12 15 18

Primes OR multiples of 3

2 3 5 6 7 9 11 12 13 15 17 18 19

There's 13 of them, so the probability of rolling a prime or multiple of 3 is 13/20

Probability of rolling a multiple of 3 is 6/20 = 3/10

Probability of rolling a prime is 8/20 = 2/5

Answer:

0.6 or [tex]\frac{12}{20}[/tex] or [tex]\frac{3}{5}[/tex]

Step-by-step explanation:

Here are the multiples of 3 (that are 20 or below) :

369121518

Here are the prime numbers (that are 20 or below):

235711131719

Some numbers are repeated in the two lists.

Here are all the numbers:

235679111213151819

12 numbers are prime or a multiple of 3.

As a fraction it will be [tex]\frac{12}{20}[/tex], or simplified to [tex]\frac{3}{5}[/tex]

As a decimal it will be 0.6
