You commented that part of the instruction included "If the theorem cannot be applied, explain the reason."

The theorem cannot be applied. Since this is not a right triangle, we cannot solve using the Pythagorean Theorem unless we are given a height. If we have the height of this triangle, then we can break it into two different right triangles and solve.

What is a right triangle? A right triangle is a triangle that has an angle measurement of 90 degrees.

In summary, this is an isosceles triangle and the Pythagorean Theorem only applies to right triangles.

If the measure of <8 is 112 degrees, the the m<6 = ?

WITCHER [35]

Answer:

112 Degrees

Step-by-step explanation:

Since 8 is 112 degrees, and 6 is opposite of 8, that means the measure of angle 6 is also 112 degrees

Keisha bought 1.2 pounds of Swiss cheese that was selling for $5.95 per pound.

Anna11 [10]

Answer:

Keisha paid $7.0805

Step-by-step explanation:

First of all, you already know that 1 pound equals $5.95. Secondly, you have to solve 5.95 divided by 10, which is 0.595. However, the question is asking for 0.2 pounds! Therefore, 0.595 * 2 = 1.19.

But we're not done yet! We still have to find the amount of money in all. 5.95 * 1.19 = 7.0805 The sum of money in all is $7.0805

Hope this helps!

The volume of a cylindrical soap dispenser is modeled by the expression below.select the true statement.a. the expression (x + 1

bulgar [2K]

Answer:

The expression $(x+1)^2$ represents the radius of the soap dispenser.

The expression $4x+1$ represents the height of the soap dispenser.

Step-by-step explanation:

The question says that the soap dispenser is in the form of a cylinder.

Now, we find the volume of the cylinder by using the given formula:

$V= \pi r^2 h$ , where V represents the volume, 'r' represents the radius, and 'h' represents the height of the cylinder.

Now, the volume is the product of radius squared and the height, if they both are functions of $x$ , then the function to represent the volume must have cubic exponents.

Since, the radius is squared in the formula and it is a function of $x$ that implies that the function of radius must have square as the exponent of $x$ , therefore, the expression $(x+1)^2$ will represent the radius of the soap dispenser and the expression $(4x+1)$ represents the height of the soap dispenser.

2. in a class of 50 students, the number of females is 2 more than 5 times the number of males. How many males and females are t

Ber [7]

Answer:

There are 8 males in the class and 42 females.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of females.

y is the number of males.

Class of 50 students

This means that $x + y = 50$

The number of females is 2 more than 5 times the number of males.

This means that $x = 5y + 2$

So, finding y, the number of males:

$x + y = 50$

$5y + 2 + y = 50$

$6y = 48$

$y = \frac{48}{6}$

$y = 8$

Females:

$x = 5y + 2 = 5*8 + 2 = 42$

There are 8 males in the class and 42 females.

Nola hiked down a trail at a steady rate for 10 minutes. Her change in elevation was −170 feet. Then she continued to hike down

madreJ [45]

Answer: First portion is greater than second portion.

Step-by-step explanation:

Time taken to hiked down a trail = 10 minutes

Change in elevation = (-) 170 feet

Speed is given by

$Speed=\frac{Distance}{Time}\\\\Speed=\frac{170}{10}\\\\Speed=17\text{ feet per minute}$

Similarly,

Time taken to hiked down a trail = 20 minutes

Change in elevation = (-)220 feet

Speed is given by

$Speed=\frac{Distance}{Time}$

$Speed=\frac{220}{20}\\\\Speed=11\text{ feet per minutes}$

So, we can see that first portion of the hike where he hiked down a trail at a steady rate for 10 minutes and her change in elevation was (-) 170 feet, was her rate of change in elevation greater.

<u>As 17 feet per minutes is greater than 11 feet per minutes.</u>
