He can go on 5 rides.

You can exploit the difference-of-squares identity,

a² - b² = (a - b) (a + b)

Then

101.5² - 100.5² = (101.5 - 100.5) * (101.5 + 100.5)

101.5² - 100.5² = 1 * 202

101.5² - 100.5² = 202

Answer:

y=1/4x + 7

Step-by-step explanation:

To find the perpendicular equation of an equation, you need to find the reciprocal of the slope (reciprocal is the opposite fraction and it's opposite sign (negative or positive)). Then you use both points in the point slope form. y-y1=m(x-x1), y-5=m(x--8), subtracting -8 from x is the same as +8, so the equation becomes y-5=m(x+8), m is the slope and our new slope is 1/4 (the reciprocal of -4x). Now your equation is y-5=1/4(x+8). All you have to do now is solve. first you multiply 1/4 by x and 8 to get rid of the parenthesis. so the equation is now y-5=1/4x+2. Now you move the 5 to the other side, so it becomes a +5 instead of -5, and you add it to 2. now the equation is y=1/4x+7.

Answer:

He should use 1/2 of a teaspoon of pepper.

Step-by-step explanation:

From the question, the soup recipe requires 1/4 of a teaspoon of pepper for every 1/2 of a teaspoon of dried basil.

Now, to determine how much pepper Terrell should use if he uses 1 teaspoon of dried basil for the huge pot of soup,

Let the quantity be x

If 1/4 of a teaspoon of pepper requires 1/2 of a teaspoon of dried basil,

then, x teaspoon of pepper will require 1 teaspoon of dried basil

x = (1/4 × 1) ÷ (1/2)

x = 1/4 ÷ 1/2

x = 1/4 × 2/1

x = 2/4

x = 1/2

∴ 1/2 of a teaspoon of pepper is required for 1 teaspoon of dried basil.

Hence, he should use 1/2 of a teaspoon of pepper.

∠ S = 55°

Step-by-step explanation:

∠ R and ∠ S are vertical angles and congruent, thus

∠ S = ∠ R = 55°

Answer:

d) m + s = 20

m = 5

Step-by-step explanation:

m + 3s = 50

m + s = 20

m + 3(20-m) = 50

m + 60 - 3m = 50

60 - 2m = 50

60 = 50 + 2m

60 - 50 = 2m

10 = 2m

In this case x = hamburgers and 2x = cheeseburgers. And sense x = 134 that is your answer.

The required 45-45-90 degree triangle is shown, where each of the two acute angles is 45 degrees and the length of the hypotenuse is equal to the length of each leg multiplied by the square root of 2.

A right-angled triangle, also known as a right triangle, is a triangle in which one of its interior angles measures exactly 90 degrees. The side opposite the right angle is called the hypotenuse, and the other two sides are called the legs.

Here,
o construct a 45-45-90 degree triangle with leg AB, we can follow these steps:

The resulting triangle will have sides AB, BC, and AC, where AB and BC are equal in length and AC is the hypotenuse.

Answer:  one solution  x + 3 = 5   x = 2   no other other value for x is possible

No solution:  (x + 3) = 2(x +3)  

Infinitely many solutions:  x+3 = 3 + x

Step-by-step explanation:

why (x + 3) = 2(x +3)  has no solution. Can you solve?

x+3=2x+6 -x=3 x=-3 substute -3 for x

(-3)+ 3)= 2[(-3) +3]

-3+3 = -6 +3

0 = -3 False!

x+3 = 3 + x  has infinitely many solutions. Substitute any number for x, and the equation is true   (5)+3=3+(5) 8=8 .  11111+3 =3+11111  11114=11114

An equation can either have: one solution, no solution, or infinitely many solutions. Some equations that can be derived from [tex]x + 3[/tex] and their solution type are:

Given that:

[tex]Expression = x + 3[/tex]

Equation with one solution

For an equation to have one solution. then the equation is consistent and dependent.

For instance:

[tex]x + 3 = 2x[/tex]

Collect like terms to solve for x

[tex]2x -x = 3[/tex]

[tex]x =3[/tex]

This means that [tex]x =3[/tex] is the only solution to [tex]x + 3 = 2x[/tex].

Hence, [tex]x + 3 = 2x[/tex] has one solution

Equation with no solution

For an equation to have no solution. then both sides of the equation are not equal

For instance:

[tex]x + 3 = x[/tex]

Collect like terms to solve for x

[tex]x- x = 3[/tex]

[tex]0 = 3[/tex]

Because 0 is not equal to 3, then [tex]x + 3 = x[/tex] has no solution

Equation with infinitely many solutions

For an equation to have infinitely many solutions. then both sides of the equation must be the same thing

For instance:

[tex]x + 3 = 2(0.5x + 1.5)[/tex]

Open the bracket

[tex]x + 3 = x + 3[/tex]

Collect like terms

[tex]x - x = 3 - 3[/tex]

[tex]0 = 0[/tex]

Because both sides are the same (i.e. 0), then [tex]x + 3 = 2(0.5x + 1.5)[/tex] has infinitely many solutions
