Please help me with this I’m really confused

Answers

Answer 1

Answer:

Answer:

13.5 minutes

Step-by-step explanation:

We can divide the final temperature to the rate of change to find the time it will take.

-10.8 ÷ -0.8 = 13.5

Check if needed.

13.5 * -0.8 = -10.8

Best of Luck!

Answer 2

Answer:

Answer: 13.5 minutes

Step-by-step explanation:

We have to divide the temperature you need to reach by the temperature than rate changes at every minute.

-10.8 ÷ -0.8 = 13.5

The answer is 13.5 minutes. Hope this helps!

What is f(5)?
A. -8
B. -1
C. 1
D. 8

Answers

Answer:

A. -8

Step-by-step explanation:

We can look at the table and figure out how we get f(5)

really its just the x value pugged into the x value for the function

after that we look on the table, f(5) is -8 because at the bottum of the table it shows 5 and -8

High Hopes^^

The answer for me is the answer -8

Match the side and angle measures of each triangle to its correct classification.

Answers

We can match like this

Angle measures : 38 degrees, 38 degrees and 104 degrees

Side lengths : 8 inches, 8 inches, 11 inches

Obtuse Isosceles Triangle

Angle measures : 22 degrees, 68 degrees, 90 degrees

Side lengths : 5 inches, 12 inches, 13 inches

Right scalene triangle

Angle measure : 26 degrees, 36 degrees, 118 degrees

Side lengths : 1.5 inches, 2 inches, 3 inches

Obtuse scalene triangle

Angle measure : 60 degrees, 60 degrees, 60 degrees

Side length : 4 inches, 4 inches, 4 inches

Acute equilateral triangle

What is an obtuse scalene triangle?

"An obtuse scalene triangle is a scalene triangle that has an obtuse internal angle. These triangles are scalene and obtuse at the same time. An obtuse angle is an angle that is greater than 90 degrees and a scalene triangle is a triangle that has all its sides with different lengths and all of its angles with different measures."

What is a right scalene triangle?

"A right scalene triangle is a scalene triangle that has exactly one right angle. A triangle is scalene if none of its sides are equal."

What is an obtuse isosceles triangle?

"The Obtuse Isosceles Triangle may be defined as the triangle in which one angle is greater than 90 degrees and two sides that forms the Obtuse Angle are equal in length."

What is acute equilateral triangle?

"In a equilateral triangle, all the angles are equal. All the angles in a triangle sum up to 180 degrees. In the acute equilateral triangle, all angles are less than 90 degrees that are acute."

In the first option

Angle measures : 38 degrees, 38 degrees and 104 degrees

Side lengths : 8 inches, 8 inches, 11 inches

We can observe that one of the angle is greater than 90 degrees and two sides of the triangle are equal in length.

The Obtuse Isosceles Triangle may be defined as the triangle in which one angle is greater than 90 degrees and two sides that forms the Obtuse Angle are equal in length.

In the second option

Angle measures : 22 degrees, 68 degrees, 90 degrees

Side lengths : 5 inches, 12 inches, 13 inches

We can observe that one of the angle is right angle and all sides are different.

A right scalene triangle is a scalene triangle that has exactly one right angle. A triangle is scalene if none of its sides are equal.

In the third option

Angle measure : 26 degrees, 36 degrees, 118 degrees

Side lengths : 1.5 inches, 2 inches, 3 inches

We can observe that an angle is greater than 90 degrees and all the sides with different lengths.

An obtuse scalene triangle is a scalene triangle that has an obtuse internal angle. An obtuse angle is an angle that is greater than 90 degrees and a scalene triangle is a triangle that has all its sides with different lengths and all of its angles with different measures.

In the fourth option

Angle measure : 60 degrees, 60 degrees, 60 degrees

Side length : 4 inches, 4 inches, 4 inches

We can observe that all the angles are equal and angles are less than 90 degrees. All the sides are equal.

In a equilateral triangle, all the angles are equal. All the angles in a triangle sum up to 180 degrees. In the acute equilateral triangle, all angles are less than 90 degrees that are acute.

We can match like this

Angle measures : 38 degrees, 38 degrees and 104 degrees

Side lengths : 8 inches, 8 inches, 11 inches

Find the value of 18 ÷ 9 ∙ 3

Answers

The value of mathematical expression by using PEMDAS rule is 6.

What is PEMDAS ?

A rule of operations explains the correct order in which math expressions should be evaluated, and we can remember those steps using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Here, the mathematical expression is given as 18 ÷ 9 ∙ 3, no solving it by using the PEMDAS rule which tells us to first divide 18 by 9 and then multiply by 3.

18/9 x 3 = 2 x 3 = 6.

Therefore, the value of mathematical expression by using PEMDAS rule is 6.

The diameter of a circle has endpoints whose coordinates are R(-2, 2) and S(4, 2). what is the length of the radius?

Answers

Answer: 3 units

Step-by-step explanation:

Using distance formula :

$√((x_2-x_1)^2+(y_2-y_1)^2)$

The diameter of the circle with endpoints R(-2, 2) and S(4, 2) will be

$d=√((4+2)^2+(2-2)^2)=√(36)=6\ units$

Since, the radius of a circle is half of the diameter.

Then the radius of the circle will be

$r=(d)/(2)=(6)/(2)=3\ units$

Hence, the radius of the circle = 3 units.

Answer:

the answer is 3

To convert from square miles to square feet,what operation will you use

Answers

The correct one is multiplication.

-- Take the number of square miles.

-- Multiply it by the fraction (5,280 feet / 1 mile)² .

-- After canceling things where possible, simplifying, and
cleaning up the product, what you have is the same area
expressed in square feet.

Multiplication because to convert from a larger unit, miles, to a smaller unit, feet, you multiply the number of miles by the number of feet in a mile to get the total number of feet.
