Answer:

the difference between the 2 pens is 4.8 cm

Answer:

8

Step-by-step explanation:

g(12) = 5/4(12)-7 = 15-7 = 8

Answer:

17= Prime number

54= Composite

77=Composite

23=Prime

Hello there!

Prime numbers have 2 factors and composite numbers have 3 or more factors.

17 is prime because it has only 2 factors: 1 and itself.

54 is composite because it has more than 3 factors.

77 is composite because it has more than 3 factors.

23 is prime because it has only 2 factors.

Hope this helps you!

Answer:

[tex]x = 1 + \sqrt{2} \ \ or \ 1- \sqrt{2}[/tex]

Step-by-step explanation:

Given;

x² - 2x - 1 = 0

Solve by completing the square method;

⇒ take the constant to the right hand side of the equation.

x² - 2x = 1

⇒ take half of coefficient of x = ¹/₂ x -2 = -1

⇒ square half of coefficient of x and add it to the both sides of the equation

[tex]x^2 + (-1)^2 = 1 + (-1)^2[/tex]

[tex](x-1)^2 = 1 + 1\\\\(x-1)^2 = 2\\\\[/tex]

⇒ take the square root of both sides;

[tex]x-1 = +/- \ \ \sqrt{2} \\\\x = 1 + \sqrt{2} \ \ or \ 1- \sqrt{2}[/tex]

Therefore, option B is the right solution.

Answer:

p = 20, q = 20, r = 30

Step-by-step explanation:

The triangle to the left of OA is isosceles ( 2 equal radii ), then the base angles are congruent, so

p = 20

The 3 angles in this triangle sum to 180°, then the angle at O is

180 - (20 + 20) = 180 - 40 = 140°

AB is a straight line so angle in triangle containing q is 180 - 140 = 40

The triangle containing q is also isosceles ( 2 equal radii ) then base angles are congruent, then

q = [tex]\frac{180-140}{2}[/tex] = [tex]\frac{40}{2}[/tex] = 20

The triangle to the right of OA is also isosceles ( 2 equal radii ) then the base angles are congruent, so

r = 30

Then p = 20, q = 20, r = 30

Step 2, she factored the trinomial incorrectly. She did, "what two numbers multiply to equal 6 but add to equal 5?" She should have asked multiply to equal -6 and add to equal 5. The correct factorization would be:

(x+6)(x-1) = 0

x = -6 and 1

Answer:

Sometimes, fractions can be written in 'improper' form, meaning that the top number (numerator) is bigger than the bottom number (denominator). So anything multiplied by a fraction like this will give a bigger number.

For example:

5 × 2/1 = 10

10 x 10/1 = 100

Step-by-step explanation:

Answer:

Step-by-step explanation:

There are two cases where this is true. When the fraction has the same numerator and denominator, or when the numerator is much larger than the denominator.

[tex]2*\frac{4}{4}=2[/tex]

[tex]2*\frac{100}{2}=100[/tex]

Answer:

850.9 feet

Step-by-step explanation:

The horizontal distance between Ryan and the dolphin is 850.907 feet.

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

We have,

Ryan is 228 feet above the water and the angle of depression to the dolphin is 15.

Using trigonometry

tan 15 = 228/ x

x= 228/ tan 15

x= 228 / 0.26794919243

x = 850.907  feet

Answer:

Tayler has 35 SHKITTLES IN ALL

Step-by-step explanation:

Since Tayler has 20 red Skittles, and the ratio of blue skittles to red skittles is 3 to 4, that means that Tayler has 3/4 as many blue skittles as she does red skittles. 3/4 of 20 is 15

20 + 15 = 35

Thus, Tayler has 35 skittles

SHKITTLES lol
