Answer:

7 and 4

Step-by-step explanation:

Answer:

7 and 4

Step-by-step explanation:

Let the number of hours Donnell practiced be d

and the number of hours Marcus practiced be m.

We can set up a system of equations.

d = m + 3

m + d = 11

Substitute the value of d that's in the first equation, into the second equation.

m + (m + 3) = 11

2m + 3 = 11

2m = 8

m = 4

Marcus practiced for 4 hours. Since Marcus and Donnell, together, practiced 11 hours, Donnell practiced for 11-4=7 hours.

Answer:

[tex]3.6 \cdot 10^8[/tex] m and [tex]3.6 \cdot 10^{11}[/tex] mm

Step-by-step explanation:

Scientific Notation:  [tex]a \cdot 10^{b}[/tex] ([tex]1<a<10[/tex])

So, Scientific Notation in meters is: [tex]3.6 \cdot 10^8[/tex] m

1 meter = 100 cm and 1 cm = 10 mm so 1 meter = 1000 mm

So, [tex]3.6 \cdot 10^8[/tex] m is [tex]3.6 \cdot 10^8 \cdot 1000[/tex] mm, so [tex]3.6 \cdot 10^{11}[/tex] mm.

The scientific notation of the number 360,000,000 is 3.6 x 10⁸ m or 3.6 x 10¹¹ mm.

Numbers that are either too large or too little to be conveniently stated in decimal form can be expressed using scientific notation. It could be called scientific form.

A numerical indication of the operation of raising to a power that is placed above and to the right of a mathematical expression.

Given that the distance is 360,000,000 meters. The distance in the scientific notation form can be written as:-

Distance  = 360,000,000 meters

Distance = 3.6 x 10⁸ m

Distance = 3.6 x 10¹¹ mm.

Pregunta completa :

Wolfrich vivió en Portugal y Brasil para aprender portugués durante un período de 14 meses. Aprendió un promedio de 130 palabras nuevas por mes cuando vivió en Portugal y un promedio de 150 palabras nuevas cuando vivió en Brasil. En total aprendió 1920 palabras nuevas. ¿Cuánto tiempo vivió Wolfrich en Portugal y cuánto tiempo vivió en Brasil?

Responder:

Portugal = 9 meses

Brasil = 5 meses

Explicación paso a paso:

Dado que:

Total de meses pasados ​​tanto en Brasil como en Portugal) 14 meses

Dejar ;

tiempo pasado en Brasil = b

Tiempo pasado en Portugal = p

Promedio de palabras aprendidas por mes en Brasil = 150

Promedio de palabras aprendidas por mes en Portugal = 139

Total de palabras aprendidas = 1920

Matemáticamente;

150b + 130p = 1920 - - - (1)

b + p = 14 - - (2)

b = 14 - p

De 1)

150 (14 - p) + 130p = 1920

2100 - 150p + 130p = 1920

2100 - 20p = 1920

2100 - 1920 = 20p

180 = 20p

p = 9

b = 14 - p

b = 14 - 9

b = 5

Por lo tanto;

Portugal = 9 meses

Brasil = 5 meses

Answer:

C. 50

Step-by-step explanation:

First, make a proportion.

16/x = 25/100

where x = total number of students

solving for x, we get x = 64.

64 - 16 girls = 48 boys

Answer:

Number of seats in Room A = 98 seats

Number of seats in Room B = 294 seats

Total number of seats for both Room A and B = 392 seats

Step-by-step explanation:

From the above question, we are told that :

A movie theater has two rooms.

Room A has 7 rows of seats with 14 seats in each row.

Hence, the total number of seats in Room A = Number of rows × Number of seats in each row

= 7 × 14 seats

= 98 seats

Room B has three times as many seats as room A.

Room B = 3 × Room A

= 3 × 98 seats

= 294 seats

How many seats are there in both rooms?

Number of seats in Room A = 98 seats

Number of seats in Room B = 294 seats

Total number of seats for both Room A and B

= 98+ 294

= 392 seats

The number of students in the school are represented by percentages

The number of students in the school is 1600

Let the number of students in the school be n.

So, the equation from the question is:

[tex]\mathbf{10\% \times n = 160}[/tex]

Divide both sides by 10%

[tex]\mathbf{n = \frac{160}{10\%}}[/tex]

Express 10% as decimal (0.10)

[tex]\mathbf{n = \frac{160}{0.10}}[/tex]

[tex]\mathbf{n = 1600}[/tex]

Hence, the number of students in the school is 1600

Answer:

Part A:

12 = a + b

Part B:

Infinitely many solutions  

There are unlimited number of combinations of real numbers whose sum is twelve

Part C:

(7.4, 4.6)

Step-by-step explanation:

Part A:

Let g = The number of female students in the mu alpha theta math team, and b = The number of male students in the mu alpha theta math team

The total number of students in the team = 12

Therefore, we have;

b + g = 12

Which is the same as 12 = a + b

Part B: The equation has infinitely many solutions because, there are unlimited number of combinations of real numbers whose sum is twelve

Part C: An ordered pair that cannot be used to represent this situation is (7.4, 4.6) because the number of boys and the number of girls must be natural numbers.

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Mean (m) = 15.28

Standard deviation (σ) = 0.75

Sample size (n) = 4

What is the probability that all four times in your sample are between 15.0 and 16.0 ms?

x = 15

Zscore = (x - m) / (σ /√n)

Z = (15 - 15.28) / (0.75)

Z = −0.3733

P(Z < - 0.3733) = 0.35446

X = 16

Z = (16 - 15.28) / (0.75)

Z = 0.96

P(Z < 0.96) = 0.83147

0.83147 - 0.35446 = 0.47701

4 * 0.47701 = 1.90804

B.)

x = 15

Zscore = (x - m) / (σ /√n)

Z = (15 - 15.28) / (0.75/√4)

Z = −0.7467

P(Z < - 0.7467) = 0.22762

X = 16

Z = (16 - 15.28) / (0.75/√4)

Z = 1.92

P(Z < 1.92) = 0.97257

0.97257 - 0.22762 = 0.74495

C.) 1.9084 > 0.74495

Start at 0 on the number line.

Note how it takes 4 steps to get to -1. Each step is shown by a unlabeled tickmark.

Since there are 4 of these steps, this means each tickmark represents 1/4 of a full unit. Therefore point A is at -1/4 since we're in negative territory.

circumference=25m

Step-by-step explanation:

circumference=πd

π=22/7

d=8

22/×8=176/8

= 25.14 to the nearest whole number is 25

Answer:

Option one, 4m, 25m

Step-by-step explanation:

You need a calculator for this question.

Radius equation: d/2

Circumference equation: 2(pi r)

or pi (d/2)^2

So we have the diameter of 8 meters.

We can get the radius by dividing by 2. Our radius is 4 meters.

We multiply pi * d to get our circumference

pi*8 = 25

Our circumference is 25m and our radius is 4m
