a) yes

b)30

c)8

Step-by-step explanation:

Answer:

90°

Step-by-step explanation:

The sum of angle 2 and angle 3 is equal to 90° because ABC is a right triangle.

Answer:

90

Step-by-step explanation:

This is a special right triangle. Now, the angles 1 is 90 degrees that means we have another 90 degrees left. We don't even need to add to know the total of angles 2 and 3 are 90 because every triangle is 180 degrees and every right angle is 90.

Answer:

15 Hydrogen 5 Nitrogen

Step-by-step explanation:

If one molecule is H3N, you multiply each quantity by 5 to get the number of atoms of hydrogen and nitrogen.

1Nx5=1N

Answer:

A

Step-by-step explanation:

Answer:

A.) y=1/2x

Step-by-step explanation:

Because the y-intercept is zero you don't need to add it so b and d are eliminated. The slope is going upwards not downwards so it eliminates c and it only lefts A with the right answer

Answer:

9 or -9

Step-by-step explanation:

the lines surrounding x are absolute value, which gets rid of negative and positives and simply ask the distance from x on a number line if the absolute value of x is 9, then x is 9 places away from 0 on the number line, so it could be 9 or -9

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:

C. 3.25 + 5.50S ≤ 30

Step-by-step explanation:

The given parameters are;

Chocolate milk = $3.25

A stack of four pancakes = $5.50

Number of pancakes in one stack = 4

Let

S = number of stacks of pancakes Benjamin buys

Cost of the pancakes Benjamin buys = $5.5 × S

= 5.5S

The maximum amount Benjamin wants his bill to amount to = $30

The inequality is

Cost of chocolate milk + Cost of pancakes Benjamin buys ≤ $30

$3.25 + $5.50S ≤ $30

3.25 + 5.50S ≤ 30.

Option C is the correct answer

C) C 3.25 + 5.50 S ≤ 30

3.25+5.50S≤303, point, 25, plus, 5, point, 50, S, is less than or equal to, 30

Answer:

y=1.25x+3

Step-by-step explanation:

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

Answer:

x = A/y

Step-by-step explanation:

Answer:

Sale price = x - 0.45x

Step-by-step explanation:

Given:

Original price = x

Discount = 45%

Find:

Sale price

Computation:

Sale price = Original price - Discount

Sale price = x - [(x)(45%)]

Sale price = x - 0.45x

Sale price = 0.55x

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:

[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.

Answer:

Step-by-step explanation:

1: Distribute or Divide (3) or Subtract (2)

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

2: Combine like terms

3x + 17 = 42.5 + 5

3: Subtract/Add

3x = 42.5 - 17 + 5

4: Divide/Multiply (If divide in first step, this one is skipped.)

x = 30.5 / 3

5: Solve

x = 10.166...

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

The true statements are (d) and (e)

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
