Answers

Answer 1
I believe it should be 0.5 x 7 as that is in a bracket and you have to deal with the bracket first before dealing with numbers outside the bracket.

5x+7=47

U pass the 7 to the 47 so now its minus

5x=47-7

Means

5x=40

Now to find x you need to divide 5 by 40

40:5=8

Means

8=x

the base of a triangle is 4 times the height. if the area is 338 square feet, then what is the height of the triangle in feet

Answers

Area of a triangle = 1/2 * b * h

b = base

h = height

We know:

h = x

b = 4x

Area = 338ft^2

Let's plug these numbers into the Area formula above.

338ft^2 = 1/2 * 4x * x

First, let's divide both sides by 1/2

676ft^2 = 4x * x

Let's simplify the right side.

676ft^2 = 4x^2

Take the sqrt of both sides.

26 = 2x

Divide each side by 2

13 = x

Remember, the height = x = 13 feet

Which of the following sets of numbers does square root of 49?

Answers

Answer:

7

Step-by-step explanation:

Natural numbers , Real numbers ,Whole numbers ,Integers , Rational numbers

sqrt(49) = 7

So this number is in the set of...

Natural numbersWhole numbersIntegersRational numbersReal numbers

The set of natural numbers is {1,2,3,...} and the set of whole numbers is {0,1,2,3,...}. Basically we just added in 0. Integers will be similar but we now have negative values too {..., -3, -2, -1, 0, 1, 2, 3, ...}

Rational numbers are anything of the form a/b with a,b being integers. In other words, if we can write the number as a fraction of two integers, then we have a rational number. In the case of 7, we have 7 = 7/1, so it is rational.

The set of real numbers includes every number type you have learned of so far (natural, whole, integer, etc). If you haven't learned about imaginary or complex numbers yet, then every number your teacher will go over is a real number.

You purchase 10,000 shares of a stock for $0.85 a share. One year later it is worth $0.95 a share. Find the profit if you sold at $0.95.

Answers

Answer:

Each share gained $0.10, which is an 11.76% increase (10/85).

The profit if the share is sold at $0.95/share, is $1000 and this can be determined by using the arithmetic operations.

Given :

You purchase 10,000 shares of a stock for $0.85 a share. After one year it is worth $0.95 a share.

The following steps can be used in order to determine the profit if the share is sold at $0.95/share:

Step 1 - The arithmetic operations can be used in order to determine the profit if the share is sold at $0.95/share.

Step 2 - According to the given data, the cost of 10000 shares of a stock is $0.85 a share. So, let the total cost of 10000 shares be 'x'. So, the value of 'x' is:

[tex]x = 10000\times 0.85\\x = \$8500[/tex]

Step 3 - Now, after one year the shares price is $0.95 a share. So, let the cost of 10000 shares after one year be 'y'. So, the value of 'y' is:

[tex]y = 10000\times 0.95\\y = \$9500[/tex]

Step 4 - So, the profit if the share is sold at $0.95/share, is:

[tex]P = y-x[/tex]

[tex]P= 9500-8500[/tex]

[tex]P= \$1000[/tex]

Therefore, the profit if the share is sold at $0.95/share, is $1000.

A total of 716 tickets were sold for the school play. They were either adult tickets or student tickets. There were 66 more student tickets sold than adult tickets. How many adult tickets were sold?

Answers

Answer:

325

Step-by-step explanation:

Let the number of adult tickets sold be x

Therefore, number of students tickets sold = x + 66

Since,

Number of adult tickets + number of student tickets = 716

Therefore,

x + x + 66 = 716

2x + 66 = 716

2x = 716 - 66

2x = 650

x = 650/2

x = 325

Hence, 325 adult tickets were sold.
