Answer:

4.4471336 * 10^2.

Step-by-step explanation:

(6.253•10^-2)(7.112x10^3)

= 6.253*7.112 * 10^-2*10^3

= 44.471336 * 10^1

= 4.4471336 * 10^2.

Answer: - radical 7 / 4

Step-by-step explanation:

draw a triangle in quadrant III

plug in correct terms

use Pythagorean theorem

to simplify down to find the opposite angle

b= rad 7

The sum of the squared lengths of the other two sides of a right triangle equals the square of the hypotenuse's length, which can be defined as follows:

[tex]\to \cos \theta =-\frac{3}{4}[/tex]

[tex]\to \sin \theta =?[/tex]

[tex]\sin \theta = \frac{opposite}{hypotenuse}\\\\\cos \theta =\frac{hypotenuse}{adjacent}\\\\[/tex]

therefore

hypotenuse= -3

adjacent= 4

Using the Pythagorean theorem to find the opposite:

Hypotenuse²= Adjacent²+ Opposite²

[tex]-3^2= 4^2+x^2\\\\9=16+x^2\\\\x^2= -16+9\\\\x^2=-7\\\\x= -\sqrt{7}\\\\[/tex]

Therefore the value of sin θ [tex]= \frac{\sqrt{7}}{-3}= \frac{\sqrt{7}}{3}[/tex]

Answer:

a group of words that share the same spelling and pronunciation but have different meanings.

Answer:

If they are pronounced the same then they are also homophones (and homonyms) – for example, bark (the sound of a dog) and bark (the skin of a tree). If they are pronounced differently then they are also heteronyms – for example, bow (the front of a ship) and bow (a ranged weapon).

Answer:

30

Step-by-step explanation:

You can use prime factorization to find the HCF of both numbers.

First, list out the prime factors of both numbers.

120: 2³ × 3 × 5

150: 2 × 3 × 5²

Next, find the common prime factors of both numbers and multiply them together.

common prime factors: 2 × 3 × 5 = 30

Answer:

Step-by-step explanation:

Answer:

Both answers should be -2 and 14.

Step-by-step explanation:

Using the quadratic formula:

[tex]x^{2}-12x-28=0\\\\x=\frac{-(-12)+-\sqrt{(-12)^2-4(1)(-28)} }{2(1)}\\\\x= \frac{12+-\sqrt{144+112} }{2}\\\\x= \frac{12+-\sqrt{256} }{2}\\\\x= \frac{12+-16 }{2}\\\\x=6+-8[/tex]

Therefore:

[tex]x_{1} =6+8=14\\x_{2}=6-8=-2[/tex]

Answer:

They would be 11.89cm long.

The total length of the two pieces of wood is 11.89cm.

When two pieces of wood are found by different people,

The total length of both pieces can be calculated by adding their respective lengths.

In this case,

One person found a piece of wood that is 7.24cm long,

While the other person found a piece that is 4.65cm long.

To determine the total length of both pieces of wood,

Simply add 7.24cm and 4.65cm together.

The sum of these two measurements is,

4.65 + 7.24 = 11.89cm.

That would be the total length of the two pieces of wood if they were attached.

Therefore, if we want to attach these two pieces of wood together, we will need a length of material that is at least 11.89cm long.

#SPJ2

Answer:

I will answer in English.

This can be translated to:

In a school, 1256 girls and 1593 boys study in three periods. how many students study at that school?

This means that we have a total of:

(1256 + 1593) students = 2849 students, divided in 3 periods.

So the total number of students in that school is 2849

And the number of students per period is:

2849/3 = 949.7

Because we can only have whole numbers here, we can say that in each period there are around 950 students.

Answer: 96%

Step-by-step explanation:

There are 25 total cyclists and 24 of those finished the race in less than 51 minutes. The question would like this 24 to be expressed as a percentage of 25.

In percentage this would be:

= Number of cyclists who finished in 51 minutes / Total number of cyclists * 100%

= 24 / 25 * 100%

= 96%

x = 12

Step-by-step explanation:

3 (x-1) = 2x + 9

3x - 3 = 2x + 9

subtract 2x from each side of the equation:

x - 3 = 9

add 3 to each side:

x = 12

Step-by-step explanation:

3x-3=2x+9

3x-2x=9+3
