Answer:

C) Since the box representing second period scores is shorter than the box for fourth period, there is less variability in the scores for second period.

If 2 cubic feet of sand weigh 90 pounds, how much do 5 cubic feet of sand weigh? what is the actual answer
nasty-shy [4]

Answer:

175

Step-by-step explanation:

It is much easier if you use the unit rate, so we'll convert the first senta\ence into a ratio. 2 cubic feet:90lb. you need to get 1 cubic foot, so divide both sides my 2, 1 cubic foot:35 pounds. now, to get five cubic pounds(See where this is going?) you multiply both sides by 5.  5 cubic feet:175lb

(these idoits make you go back and forth in solving problems)

Which of the algebraic expressions are not linear expressions? Select all that apply. a. 3x - 2 b. -9y c. -7x^2^ + 4x d. -1/2x^2
Sedaia [141]

Answer:

c, d and e

Step-by-step explanation:

A linear expression is an expression in which sum of exponents of variables is at most 1 in each of its terms.

Option a: 3x - 2

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option b: -9y

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option c: -7x^2 + 4x

Here, the highest exponent of the variable is 2.

So, it is NOT a linear expression.

Option d: -\frac{1}{2} x^2

Here, the exponent of the variable is 2.

So, it is NOT a linear expression.

Option e: 8xy

Here, sum of exponents of variables is 2.

So, it is NOT a linear expression.

Hence, c, d and e are NOT algebraic expressions.

The general form of a circle is given as x^2 + y^2 + 4x - 12y + 4 = 0.
stepan [7]
If you can rewrite the formula as (x-a)² + (y-b)² = r², the center is at (a,b) and the radius is r.

If you work out this equation, and map it to the original, you will find that the +4x term hints that a = 2 (double product) and -12y hints that b=-6, and r=6.

So, the formula can be written as (x+2)² + (y-6)² = 6² and the center is at (-2,6) and the radius is 6.
