Step-by-step explanation:

we have, 5y +5=40

5y = 40 - 5

5y=35

y= 35/5

x=7

and, x + 10 = 13

x=13-10

The answer is:  " 6³ " .

__________

Step-by-step explanation:

Note:  " (6)(6)(6) " ;  is the value of the  

[number "6" ; multiplied by that same number, "6" —two additional times;

   → so the same number, "6" ;  being multiplied:  "3 (three) times'

                 =  6 * 6 * 6  =  6³  ;  that is:  the number "6", raised to the third power (as an exponent);

    →  since: there are 3 (three) of the same numbers being multiplied;

            ⇒ hence the exponent, "3" .
__________

The answer is:  " 6³ " .

Answer:

3/14

Step-by-step explanation:

Put the number of students that want to be a therapist AND have a fear of height (this would be 3) over the TOTAL amount of students in the sample, in this case it's 14.

so it's 3/14 and it doesn't simplify

you're welcome

Answer:

21%

Step-by-step explanation:

First we need to find the total amount of people that did the personality test. We can do that by adding all the numbers in the table

[tex]4+5+2+3=14\\[/tex]

now, to find the percentage of students that want to be a therapist and a fear of heights, we simply divide the number of students who fit that demographic by the total number of students

[tex]3/14= 0.214[/tex]

therefore, there is a 21% chance of picking a student in that demographic at random

We add the two fractions:

6 3/8 + 7 2/5 = 13 31/40 boxes of candy bars.

Answer:

Add the two fractions 6 3/8 + 7 2/5 = 13 31/40

Step-by-step explanation:

First multiply the whole numbers by the denominator then add it to the numerator, then find the most common factor (in the denominators) which is 40 (8x5 and 5x8) and multiply the numerator by the same number as the denominator, you will get 255/40 and 296/40 add them then simplify then you will get 13 31/40, thank you.

The equations secx+cosecy = 2, and sinx+cosy=k are trigonometry equations

The result of [tex]\frac {3k}4[/tex] is [tex]\frac{3\sin(y)\cos(x)\sin(x) + 3\sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]}[/tex]

The equations are given as:

secx+cosecy = 2, and sinx+cosy=k

Divide both equations

[tex]\frac{\sin(x) + \cos(y)}{\sec(x) + \csc(y)} = \frac k2[/tex]

Divide through by 2

[tex]\frac{\sin(x) + \cos(y)}{2[\sec(x) + \csc(y)]} = \frac k4[/tex]

Express sec and cosec as inverse ratios

[tex]\frac{\sin(x) + \cos(y)}{2[1/\cos(x) + 1/\sin(y)]} = \frac k4[/tex]

Take the LCM

[tex]\frac{\sin(y)\cos(x)[\sin(x) + \cos(y)]}{2[\cos(x) + \sin(y)]} = \frac k4[/tex]

Expand

[tex]\frac{\sin(y)\cos(x)\sin(x) + \sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]} = \frac k4[/tex]

Multiply through by 3

[tex]\frac{3\sin(y)\cos(x)\sin(x) + 3\sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]} = \frac {3k}4[/tex]

Rewrite as:

[tex]\frac {3k}4 =\frac{3\sin(y)\cos(x)\sin(x) + 3\sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]}[/tex]

Hence, the result of [tex]\frac {3k}4[/tex] is [tex]\frac{3\sin(y)\cos(x)\sin(x) + 3\sin(y)\cos(x)\cos(y)}{2[\cos(x) + \sin(y)]}[/tex]

Answer:

The volume of the 80% ammonia that is to be drained before water is added is 7.5 quartz

Step-by-step explanation:

The volume of the ammonia and water mixture = 5 gallons

The percentage of ammonia in the mixture = 80%

The volume of ammonia desired = 5 gallons

The percentage concentration of ammonia desired = 50%

The diluting solution = Pure water

The measure of 4 quarts = 1 gallon

Therefore, we have, by equivalence solutions;

80% × x gallon = 50% × 5 gallons

x gallon = 50% × 5 gallons/(80%) = 3.125 gallons

x = 3.125 gallons

The volume of the 80% ammonia that is to be drained = 5 gallons - 3.125 gallons = 1.875 gallons

4 quarts = 1 gallon

1 gallon = 4 quarts

∴ 1.875 gallons = 4 × 1.875 quartz = 7.5 quartz

The volume of the 80% ammonia that is to be drained before water is added = 7.5 quartz

Step-by-step explanation:

again, in a geometric sequence all terms are created by multiplying the previous term by a constant factor.

7640 × f = 764

f = 764/7640 = 1/10

a1 = 7640

a2 = a1 × 1/10 = 7640 × 1/10 = 764

a3 = a2 × 1/10 = a1 × 1/10 × 1/10 = 7640 × 1/100 = 76.4

an = 7640 × (1/10)^(n-1)

a6 = 7640 × (1/10)⁵ = 7640 × 1/100000 = 0.0764

  (b)  The result of adding two polynomials is always a polynomial.

Step-by-step explanation:

A set is "closed" under a particular operation if performing that operation on members of the set always results in a member of the set.

Adding two polynomials always results in a polynomial, so we can say "polynomials are closed under addition."

Fractions and whole numbers ordered on the number line are similar because it tells parts throughout the line, like skip counting using adding or subtraction for example.

What's different from them is because the fractions tell the parts more detailed between the whole numbers, such as 2 3/4 as a fraction on the number line. And 3 as a whole number on the number line.

Answer:

7cm, assuming the question is phrased as noted below.

Step-by-step explanation:

I'll interpret "If the length of a rectangle doubles its width." as "If the length of a rectangle is double its width.

Let L be the width, and L the length

L = 2W

The perimeter of a rectangle is 2L + 2W

We can use L instead of 2W,  and that gives us:

  21 cm = 2L + L

21 cm = 3L

L = 7 cm
