In the diagram, ΔGEF and ΔHEF are congruent. What is the value of x?

Answer:

27

Step-by-step explanation:

30% of 90 is 27

30/100 = ?/90

by cross multiplying, we can see that 30 times 90 is equal to 2700.

2700/100 = 27

? = 27

PLEASE GIVE BRAINLIEST!

Hope this helps :)

Answer:

An angle whose measure is equal to 90° is called a right angle.

An angle whose measure is more than 0° but less than 90° is called an acute angle. Angles having magnitudes 30°, 40°, 60° are all acute angles.

An angle more than 90 degrees and less than 180 degrees, is called an obtuse angle.

For the cosecant we will get:

   [tex]csc(\pm \frac{pi}{4}) = \frac{1}{sin(\pm \frac{pi}{4})} = \pm \frac{2}{\sqrt{2} } = \pm \sqrt{2}[/tex]

So the correct option is the third one.

First, we can write:

[tex]csc(x) = \frac{1}{sin(x)}[/tex]

Now, remember that:

[tex]cos(x) = \frac{\sqrt{2} }{2} \\\\for\ x = \pm \frac{pi}{4}[/tex]

And for the sine we have:

[tex]sin(pi/4) = \frac{\sqrt{2} }{2} \\\\sin(-pi/4) = -\frac{\sqrt{2} }{2} \\[/tex]

Then the cosecant for these possible values of x gives:

[tex]csc(\pm \frac{pi}{4}) = \frac{1}{sin(\pm \frac{pi}{4})} = \pm \frac{2}{\sqrt{2} } = \pm \sqrt{2}[/tex]

So the correct option is the third one.

The answer for the given equation in decimal is -2.357.

An equation is a mathematical expression in terms of one or more unknown variable.

Given the equation : 2 +2/3x =3/7

Simplify by Cross multiplication, we get

6 +2x = 9/7

Simplifying further and solving for x

2x = 9/7 -6

2x = -4.714

x = -2.357

Hence, the equation is solved and the value of x is  -2.357.

Answer:

The shape of the data in the histogram is Symmetrical.

Step-by-step explanation:

This is because the distribution, or data set is the same to the left and right of the center point.

This is how the linear function looks.

The best definition of the phrase "like terms" is as follows: terms that have identical variable parts.

Like terms is used to describe terms that contain the same variable which is raised to the same power.

Algebra is an aspect of mathematics that involves the system of computation using letters or other symbols to represent numbers.

Using it's concept, it is found that the probability of an odd number other than seven being generated is of 40.0%.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

For an experimental probability, these number of outcomes are taken from previous trials.

In this problem, 200 numbers have been generated, and 80 are odd numbers that are not seven, hence the probability is given by:

p = 80/200 = 0.4 = 40%.

Answer:

11 points

Step-by-step explanation:

Claire had 11 points  because 18-7=11

C+7 =18 is the equation which can be used to find the Claire score C, the value of C is 11.

Two or more expressions with an Equal sign is called as Equation.

Given that Ava scored 18 points in a basketball game.

Let Ave score be represented as A.

Ave scored seven points more than Claire.

Let C be the Claire score.

A=7+C

As given Ava scored 18 points in a basketball

so the value of A is 18

18=7+C

Now let us find the value of C

Subtract 7 from both sides

18-7 =C

11=C

Hence, C+7 =18 is the equation which can be used to find the Claire score C, the value of C is 11.

Using a trigonometric realtion, we can see that x = 23.18cm

Here we have a right triangle, we can see that y = 6cm, and the angle theta is 15°.

Notice that y is the opposite cathetus to the known angle, and we want to find the value of x, which is the hypotenuse.

Then we can use the trigonometric relation:

sin(a) = (opposite cathetus)/hypotenuse.

Reaplacing what we know, we will get:

sin(15°) = 6cm/x

Solving that for x:

x = 6cm/sin(15°9

x = 23.18cm

The probability that the next elk that will be caught will be unmarked is 5400/ 5625, 0.96 and 96%

The probability that the next wolf that will be caught will be unmarked is 696 / 928,  0.75 and 75%.

Probability determines the odds that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that the next elk that will be caught will be unmarked = number of unmarked elks / total number of elks

number of unmarked elks  = 5625 - 225 = 5400

5400/ 5625 = 0.96 = 96%

The probability that the next wolf that will be caught will be unmarked = number of unmarked wolfs / total number of wolfs

number of unmarked wolfs  = 928 - 232 = 696

Based on the above, it can be inferred that the best option to produce the 15,000 units is the factory with the lowest cost per unit.

Unit cost is a term to refer to the value per unit of a product that a factory charges to produce it.

In this case, the best alternative to produce 15,000 products is the factory with the lowest cost per unit, since this will reduce the cost of the order.

To find the cost per unit we divide the total cost of the order by the number of units. For example:
