Identify the hypothesis of the statement. If a number is negative, then the number is less than zero. A) a number is negative B) a number is positive C) the number is less than zero D) the number is greater than zero

Answers

Answer: A) a number is negative

Step-by-step explanation:

A conditional statement is written as:

If P, then Q.

Where P is the hypothesis and Q the conclusion.

In this case, we have:

If a number is negative, then the number is less than zero.

then we have:

P = a number is negative.

Q = the number is less than zero.

Then the hypothesis will be "a number is negative"

The correct option is A.

Which two ratios represent quantities that are proportional?

A 22/33 and 14/21
B 48/60 and 35/42
C 25/28 and 5/7
D 16/13 and 13/16

Please help

Answers

A: 22/3 and 14/21 = 1/3

The two ratios represent proportional quantities is A: 22/3 and 14/21 = 1/3

When do two ratios form a proportion?

Two ratios form a proportion if the simplified form of both ratios comes out as the same ratio. Suppose that we've got two quantities with measurements as 'a' and 'b' Then, their ratio(ratio of a to b) a:b

We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Remember that the ratio should always be taken of quantities with the same unit of measurement. Also, the ratio is a unitless(no units) quantity.

A.) 22/33 and 14/21

Here. the two ratios represent quantities that are proportional to 1/3.

B.) 48/60 and 35/42

Here. the two ratios represent quantities that are not proportional.

C.) 25/28 and 5/7

Here. the two ratios represent quantities that are not proportional.

D.) 16/13 and 13/16

Here. the two ratios represent quantities that are not proportional.

Hence, The two ratios represent proportional quantities is A: 22/3 and 14/21 = 1/3

A vine called the mile-a-minute were is known for growing at a very fast rate it can grow up 2ft per day how fast in inches per hour can the mile-a-minute weed grow up to?

Answers

Answer:

1 inch/hr

Step-by-step explanation:

Rate of growing of weed mile-a-minute = 2 ft per day

To find:

Rate of growth of weed in inches per hour ?

Solution:

First of all, let us have a look at the following units conversion:

1 ft contains 12 inches

and 1 day is equal to 24 hours.

Rate of growth of weed is Length divided by number of days.

2 ft per day means Length of 2ft divided by 1 day.

i.e.

[tex]\dfrac{2\ ft}{1\ day}[/tex]

Let us put the units for conversion as discussed above:

[tex]\dfrac{2\times 12\ inches}{24\ hours}\\\Rightarrow \dfrac{24\ inch}{24\ hours}\\\Rightarrow \bold{1\ inches/hr}[/tex]

So, the answer is: 1 inch/hour

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The three figures are shown in the picture.

After analysis:

2(3) + 1  = 7

2(4) + 1  = 9

2(5) + 1  = 11

The standard form:

y = 2(x+2) + 1

y = 2x + 4 + 1

y = 2x + 5

Thus, the equation that would model the tile pattern above where x represents the figure number and y represents the number of tiles is y = 2x + 5.

João emprestou R$ 1000,00 a seu amigo José. Para que José conseguisse o empréstimo com o amigo, foram definidas as seguintes condições de pagamento: prazo de 6 meses e taxa de juros simples de 10% ao trimestre. Sendo assim, passados os seis meses do empréstimo, quanto o amigo José terá de pagar ao amigo João? a) R$ 100,00 b) R$ 1.100,00 c) R$ 200,00 d) R$ 1.200,00 e) R$ 1.400,00

Answers

Answer:

La opción correcta es;

d) R $ 1.200,00

Step-by-step explanation:

El monto que Joao prestó a José = R $ 1.000,00

La duración del préstamo = 6 meses

El plazo de interés del préstamo = interés simple del 10% por trimestre

La cantidad que José tiene que pagarle a Joao después de 6 meses viene dada por la siguiente fórmula de interés simple;

A = P · (1 + r · t)

A = La cantidad que José tiene que pagarle a Joao después de 6 meses

P = La cantidad que Joao prestó a José = R $ 1.000,00

r = La tasa de interés = 10% / trimestre = 10% / (3 meses) = 0.1 / (3 meses)

t = La duración del préstamo = 6 meses

Por lo tanto, al sustituir los valores anteriores en la fórmula de interés simple, tenemos;

A = R $ 1.000,00 × (1 + 0,1 / (3 meses) × 6 meses) = R $ 1.000,00 + R $ 200,00 = $$ 1.200,00

El monto que José debe pagar a Joao después de 6 meses = R $ 1.200,00
