Answer:

110

Step-by-step explanation:

If 12% studied Spanish, then 88% did not. The ratio of those who did not to those who did is ...

  88 : 12 = 22 : 3

Then the number of students who did not study Spanish is ...

   (22/3)×15 = 110 . . . . did not study Spanish

22:3 is a reduction of the ratio 88:12, by factoring 4 from each number. 15 is the number of students corresponding to 12% of the class. It is found in the problem statement. Essentially, we're saying that we want to know the number of students in the other 88% of the class, given that 15 students make up 12% of the class. There are many ways to write equations for this. I think this proportion is the easiest to think about.

If F is the size of the freshman class, and n is the number Not studying Spanish, you have 12%·F = 15, and 15 + N = F. You can solve the first equation for F, then the second equation for N, which is what you really want to know. F = 15/.12 = 125; N = F -15 = 125-15 = 110.

These two equations are reasonably straightforward, but to my lazy way of thinking, it is an extra equation and an extra calculation that are not needed to get to the answer.

You don't need to reduce the ratio from 88/12 to 22/3 to work the problem using ratios. The only reason for doing that is so there is a 3 in the denominator that cancels a factor of 3 in 15, so the only math you really need to do is 22·5 = 110. It helps immensely to know your multiplication tables, and to be able to recognize multiples of 2 and 4.

Answer:

Jamar can ride his bike 20 miles in 1 hour.

He went 6 miles in 36 minutes.

Applying the Pythagorean Theorem and using the rules of significant digits, the length of the other leg of the right triangle is approximately 2.61 meters.

Recall:

Using the Pythagorean Theorem, we are going to find the length of the other leg of the triangle that has:

[tex]2.27^2 + b^2 = 7.76^2\\\\b = \sqrt{7.76^2 - 2.27^2} \\\\b = 2.607[/tex]

Therefore, applying the Pythagorean Theorem and using the rules of significant digits, the length of the other leg of the right triangle is approximately 2.61 meters.

-3x + 50 = 101

       -50   -50      subtract 50 from both sides, 50's cancel out from the left.

___________     solve for 101 - 50.

-3x = 51

___  ___              divide -3 on both sides, -3's cancel out on the left.

-3     -3                 solve for 51 ÷ -3.

Step-by-step explanation:

If the price increases 3/4 per share, the new price of the stock =

6¾ + ¾ =

27 /4 + ¾ =

30 /4 =

15/2 or 7½

The new price of the stock which increases 3/4 per share is $ 7 1/2.

Given data:

A stock is selling on a stock exchange for 6 3/4 dollars per share.

If the price of the stock increases by 3/4 dollars per share, you can add 3/4 to the current price of 6 3/4 dollars per share:

6 3/4 + 3/4

To add the whole numbers and fractions separately:

6 + 0 + 3/4 + 3/4

Adding the whole numbers and fractions:

6 + 1 1/2

A = 7 1/2

Hence, the price of the new stock is $ 7 1/2

The relation is not a function. All you need to solve this problem is the following: Relations are NOT functions when the domain values repeat!

Note: The domain is the set of input values. The domain is x, the first number in the pair. For example, in the pair (0, 2), the domain is 0.

In the relation {(0,2),(2,4),(1,7),(2,5)}, 2 is repeated two times, which, by definition, means that the relation is not a function.

Reformatting the input :

Pulling out like terms

3.1     Pull out like factors :

  8x2 - 8  =   8 • (x2 - 1)  

Trying to factor as a Difference of Squares:

3.2      Factoring:  x2 - 1  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 1 is the square of 1

Check :  x2  is the square of  x1  

Factorization is :       (x + 1)  •  (x - 1)

Theory - Roots of a product

4.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

Equations which are never true:

4.2      Solve :    8   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.3      Solve  :    x+1 = 0  

Subtract  1  from both sides of the equation :
