Answer:

here you go!

Step-by-step explanation:

The 30°-60°-90° refers to the angle measurements in degrees of this type of special right triangle. In this type of right triangle, the sides corresponding to the angles 30°-60°-90° follow a ratio of 1:√ 3:2.

Divide the pages read by the portion read:

Answer:

\frac{2}{ x^{2} }  +  \frac{4}{ x^{2} } =  \frac{2+4}{ x^{2}}=  \frac{6}{ x^{2} }  

Step-by-step explanation:

When we add two expression in fraction we take Least common multiple of two expression  in the denominator

Here we have expression  

Now, we write a common denominator

rewrite the expression

Now, we combine the numerator 2+4 is equal to 6

So, we will get   = \frac{2}{x^{2}}+ \frac{4}{x^{2}} =\frac{6}{x^{2} }

Answer:

Independent events, 1/16

Step-by-step explanation:

What we must take into account is that they are 2 different bags, because in one bag are the black pieces and in another bag are the white feed, regardless of which piece is removed, one event has nothing to do with the other event being different bags.

Which means that they are independent events.

And the probability for each case would be 1/16, because the probability is one piece out of 16 that is in each bag.

Answer:

2 1/4 < x ≤ 4

Step-by-step explanation:

12x−39≤9 AND−4x+3<−6

Solve them separately and then put back together

12x−39≤9

Add 39 to each side

12x−39+39≤9+39

12x ≤48

Divide by 12

12x/12 ≤48/12

x ≤4

Now the other inequality

−4x+3<−6

Subtract 3 from each side

−4x+3-3<−6-3

-4x < -9

Divide by -4, remembering to flip the inequality

-4x/-4 > -9/-4

x > 2 1/4

put back together

x > 2 1/4 and x ≤4

2 1/4 < x ≤ 4

Answer:

2.25<x≤4

Step-by-step explanation:

12x−39≤9 ⇒ 12x≤ 48 ⇒ x≤4

−4x+3<−6 ⇒ -4x < -9 ⇒ x> 9/4= 2.25

2.25<x≤4

or

x= (2.25, 4]

Answer:

the answer is c

Step-by-step explanation:

What you meant was range. The range scales from top to bottom. You can know this by graphing and practicing memorizing these function's domain and range.

Function:                  Range:

f(x) = -√x                    y ≤ 0

p(x) = ∛2-x          All real numbers

w(x) = 2 + √x             y ≥ 2

r(x) = -2 + √2-x          y ≥ -2

k(x) = 2 - √x               y ≤ 2

v(x) = √-x                   y ≥ 0

Answer:

A. y = 6

Step-by-step explanation:

Y= 0 is equation of x - axis

 equation of any straight line which is  parallel to x-axis and at  distance of a from it is given y = c.

Therefore,  from the given option only option A y =6 is in form of y = a and hence is the correct answer.

_______________________________________

Also we know that for two lines to be parallel , their slope should be equal.

slope of line y = mx + c is m

slope of y = 0 here m = 0, hence slope is 0

out of the given option

only for y - 6 slope is 0 and hence it is the correct answer.

Answer:

data from least to Greatest:

2.6, 3 , 4.9 , 5 , 5 , 6 , 6 , 7.9 , 8 , 8.2

Step-by-step explanation:

I got it from Khan Academy

The interquartile range (IQR) of the data set is 3.

The given data set is 5, 8.2, 6, 7.9, 5, 2.6, 3, 4.9, 6 and 8.

We need to find the interquartile range (IQR) of the data set.

To find the interquartile range (IQR), ​first, find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

Now, the order of data from least to greatest is 2.6, 3, 4.9, 5, 5, 6, 6, 7.9, 8, 8.2.

Q1=4.9 and Q3=7.9

So, IQR=Q3-Q1

=7.9-4.9=3

Therefore, the interquartile range (IQR) of the data set is 3.

Answer:

x = 1 2/3 hours

Step-by-step explanation:

We can use ratios to solve

150 miles          100 miles

---------------- = ---------------

2.5 hours          x hours

Using cross products

150x = 2.5*100

divide each side by 150

150x/150 = 250/150

x = 1 2/3 hours
