7 0

Answer:

120

Step-by-step explanation:

80 represents the 2

Do 80 / 2 to get one 80 /2 = 40

So 1 would equal 40

Do 40 * 3 = 120 to get the three which represents the number of adults

What is the distance between point P and point R?

stealth61 [152]

Answer:

PR = 10

Step-by-step explanation:

PR = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The coordinates for P and R are (0,4) and (-6,-4) respectively.

So you plug in the values:

PR = $\sqrt{(-6-0)^2+(-4-4)^2}$

PR = $\sqrt{(-6)^2+(-8)^2}$

PR = $\sqrt{36+64}$

PR = $\sqrt{100}$

PR = 10

In a right triangle, the ____________ of an angle can be found by dividing the length of the opposite leg by the length of the t

damaskus [11]

The correct answer for the completion exercise shown above is: sine.

Therefore, the complete text is shown below: "<span>In a right triangle, the sine of an angle can be found by dividing the length of the opposite leg by the length of the triangle's hypotenuse".
</span>
A right triangle is a triangle that has an angle of 90 degrees.

The sine is one of the most common trigonometric functions. Therefore, you have that the sine of an angle is:

Sin(α)=opposite/hypotenuse

Jim needs to rent a car. A rental company charges $21.00 per day to rent a car and $0.10 for every mile driven.

Ulleksa [173]

Answer:

$21d+25\leq 115$

Max is 4 days.

Step-by-step explanation:

An inequality is a math statement with more the one solution. The solution has a range of values for which the inequality can be satisfied. It has the same following components as an equation: variables and operations. However, the equal sign is replaced by an inequality sign: $,\leq,\geq$ .

We start by choosing a variable for an unknown value. Here is it the number of days he rents the car. We choose d.

We know he rents it for $21 pr day or 21d for any number of days. We also know her will drive 250 miles at $0.10 per mile or 0.10(250). We will combine the two into an expression.

21d + 0.10(250)

We know his limit is $115. This means he can rent the car for any number of days until he reaches $115. The charge must be less than or equal to 115.

So we write $21d+0.10(250)\leq 115$ .

To find the number of days he can rent the car, we solve for d using inverse operations.

$21d+0.10(250)\leq 115\\21d+25\leq 115\\21d+25-25\leq 115-25\\21d\leq 90\\\frac{21d}{21} \leq \frac{90}{21}\\d\leq 4.3$

This means Jim can rent the car up to 4 days. The 5th day will put the cost over $115.

Marble Slab Creamery is creating a cone-shaped paper wrapper for its new green Baby Yoda waffle cone. The wrapper should have a

mote1985 [20]

Answer:

3927 cm² wrapping paper will be required.

Step-by-step explanation:

Lateral surface area of a cone shaped wrapper = πrl

where, r = radius of the waffle cone

and l = slant height of the cone

It has been given in the question, radius 'r' = 5cm

and lateral height 'l' = 10 cm

Lateral surface area of the cone = π(5)(10)

= 50π

= 157.08 cm²

If they plan to make 25 waffles then wrapper paper required

= 25×157.08

= 3927 cm²

Therefore, 3927 cm² wrapping paper will be required.
