Answer:

y = 140°

Step-by-step explanation:

we know that sum of two opposite interior angles are equal to one exterior

=> y = 120° + 20°

Answer:

with what???

Step-by-step explanation:

The sale price 's' of a book is $3.50 less than the original price 'p'. This situation is represented by the given equation s = p - 3.5.

Two or more expressions with an Equal sign is called as Equation.

The given equation is s = p - 3.5, where 's' represents the sale price and 'p' represents the original price of a book.

The equation shows that to get the sale price 's', the original price 'p' is reduced by $3.50.

If the sale price 'p' of a book is $3.50 less than the original price 's', then we can rewrite the equation as p = s + 3.5.

This situation is not represented by the given equation.

If the sale price 's' of a book is $3.50 more than the original price 'p', then the equation would be s = p + 3.5.

This situation is also not represented by the given equation.

Hence, the sale price 's' of a book is $3.50 less than the original price 'p'. This situation is represented by the given equation s = p - 3.5.

Answer:

  3 times the smaller triangle base

Step-by-step explanation:

The volume is proportional to the height and to the area of the base.

If the height is unchanged, the larger pyramid must have a triangular base with an area that is 9 times the smaller base area.

Since the bases are similar, the area ratio is the square of the side length ratio. The side lengths of the larger base triangle must be √9 = 3 times the side lengths of the smaller base triangle.

Answer:

A. 4x * 2x^2 + 4x * (-2) + 1 * 2x^2 + 1 * (-2)

Step-by-step explanation:

We have the binomial (4x + 1)(2x^2 - 2) and are asked to see how it looks like expanded.

When solving binomials, we need to follow the FOIL method :

First - First number in first parenthesis multiplied by first number in second parenthesis

Outer - First number in first parenthesis multiplied by second number in second parenthesis

Inner - Second number in first parenthesis multiplied by first number in second parenthesis

Last - Second number in first parenthesis multiplied by second number in second parenthesis

If we follow the definitions given, we can find our correct answer and also see where all the other answers mess up at :

A. 4x*2x^2+4x*(-2)+1*2x^2+1*(-2)

This follows FOIL entirely from start to finish.

B. 4x*2x^2+4x*(-2)+1*4x+1*(-2)

This did not follow the Inner part of FOIL.

C. 4x*2x^2+4x*(1)+1*2x^2+1*(-2)

This did not follow the Outer part of FOIL.

Answer:

8x+4 and 2x-4

Step-by-step explanation:

We are going to use factoring to make equivalent expressions. What you do is you take the number next to the parenthesis and multiply it with what is inside the parenthesis. So it would be 8x+4 and 2x-4. Hope this helps! :)

Step-by-step explanation:

Answer:

[tex]\overline {DC}[/tex] = 7

[tex]\overline {BD}[/tex] = √35

[tex]\overline {AB}[/tex] = 2·√15

Step-by-step explanation:

Please find attached the drawing of right triangle ABC created with MS Visio

Let 'x' represent [tex]\overline {BD}[/tex] let 'y' represent [tex]\overline {DC}[/tex], and let 'z' represent [tex]\overline {AB}[/tex], we get;

5² + x² = z²...(1)

x² + y² = (2·√21)² = 84

x² + y² = 84...(2)

84 + z² = (5 + y)²...(3)

From equation (1), we have;

x² = z² - 5²...(4)

From equation (2), and equation (4), we have;

x² + y² = 84 = (z² - 5²) + y² = 84

∴ z² = 84 - y² + 5² = 109 - y²

z² = 109 - y²...(5)

From equation (3), and equation (5), we have;

84 + z² = (5 + y)² = 84 + (109 - y²) = (5 + y)²

84 + (109 - y²) = (5 + y)²

(5 + y)² - (84 + (109 - y²)) = 0

2·y² + 10·y - 168 = 0

y² + 5·y - 84 = 0

y = (-5 ± √(5² - 4 × 1 × (-84)))/(2 × 1)

y = 7, or y = -12

We note that 'y' is a natural number, therefore, the correct option of the two options is y = 7

y = [tex]\overline {DC}[/tex] = 7

From equation (2), we have;

x² + y² = 84

x² = 84 - y² = 84 - 7² = 35

x = √35

x = [tex]\overline {BD}[/tex] = √35

z² = 109 - y²

∴ z² = 109 - 7² = 60

z = √60 = 2·√15

z = 2·√15

z = [tex]\overline {AB}[/tex] = 2·√15.

Step-by-step explanation:

The whole numbers between 20 and 50  are 20, 24, 28, 32, 36, 40, 44, 45, 48.

A whole number is defined merely as any positive number that does not consider a fractional part or any decimal part of the numbers.

For example, the numbers 0, 1, 2, 3, 4, 5, 6, and 7 are all whole numbers. Numbers such as -9, 6.2, or 2 ½ are not whole numbers.

Therefore, the whole numbers that are on the gap between of 4 between 20 and 50 are the  20, 24, 28, 32, 36, 40, 44, 45,  48.

Answer: 22,000 * 1.25^ x

Step-by-step explanation:

The number of pages grows at 25% every week. This number is based on the previous week's number of pages so the increase in page number is being compounded.

Use the future value equation to determine the number of pages after x weeks.

FV = Amount * ( 1 + rate of increase) ^ time

= 22,000 * ( 1 + 25%) ^ x

= 22,000 * 1.25^x

Answer:

Probability that Billy will roll a 5 or higher [tex]=\frac{1}{3}[/tex]

Billy needs to roll a 5 or higher to win the game.

So,

Favorable outcomes are [tex]5,6[/tex]

Answer:

120m

Step-by-step explanation:

Each side of square have same length, assume x for one side of square:

x^2=900

x=30

perimeter:30x4=120m

Answer:

120 square meters

Step-by-step explanation:

Since area is base times height and this is a square, we know all sides are the same length. Take the square root of 900 and you will get 30, meaning each side is thirty meters long. 30 x 4 = 120, that’s your perimeter. Hope this helps!
