A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. What was the temperature:
1 hour ago?
3 hours ago?
Half an hour ago?

Answers

Answer 1

Answer:

For one hour ago, it would be 3 C, 3 hours ago, it would be 9 C, and half an hour ago, it would be 1.5 C.

Step-by-step explanation: It's quite straightforward. Since the temperature is dropping, and you want to find the temp. of earlier times, just add 3C to every hour (1.5 for a half) it was ago, to what the temperature currently is now. (0 C).

Answer 2

1 hour is 3 Celsius, 3 hours is 9, and half an hour is 1.5 :D

help me plzz!

Answers

Answer: 1.5

Step-by-step explanation: Given:

A=1/10×5 + 11²

B= 5 - 11²

If c = A + B

c = ( 1/10×5 +11²) + ( 5 - 11² )

= ( 5/10 + 121) + ( 5 - 121)

= ( 121.5) + ( -120)

= 121.5 - 120

= 1.5

the answer your looking for is 1.5

The area of a triangle is found using the formula bh/2, where b is the base and h is the height. What is the area in square inches of a triangle with a height of 6 inches and a base of 8 inches?

Answers

Answer:

A = 24 in^2

Step-by-step explanation:

A = 1/2 bh

Let b = 8 and h = 6

A = 1/2 (8)(6)

A = 24 in^2

Given :

The area of a triangle is found using the formula bh/2, where b is the base and h is the height. What is the area in square inches of a triangle with a height of 6 inches and a base of 8 inches?

Solution :

Given Data :

Height = 6 inches

Base = 8 inches

Formula for Area of traingle is :

[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \star \: \: \: \red{ \underline{ \red{ \overline{ \orange{ \boxed{ \pink{\frak{Area \: of \: Triangle = \frac{1}{2} × Base × Height }}}}}}}}[/tex]

So, putting the values of Base and Height we get

[tex] \leadsto \frak{Area = \frac{1}{2} × 8 \times 6 }[/tex]

[tex] \leadsto \frak{Area = \frac{1}{ \cancel2} × \cancel 8 \times 6 }[/tex]

[tex] \leadsto \frak{Area = 4 \times 6 }[/tex]

[tex] \leadsto \frak{Area = 24 \: {in}^{2} }[/tex]

Hence, the area of the traingle is 24 inches²

An adult ticket is twice the cost of a child's ticket. Angela paid $ 28 for two adult tickets and three children's tickets. Which of the
following equations could be used to find the price of a child's ticket?
(A) x + 2x = 28
(B) 3x + 2(2x) = 28
(C)3(2x) + 2x = 28
(D) 3x + 2x = 28

Answers

B = 3 x + 2 ( 2x ) = 28

The following equations could be used to find the price of a child's ticket, 3x + 2(2x) = 28, the correct option is B.

What is an Equation?

An equation is a mathematical statement formed when two expressions are equated using an equal sign.

The equations are useful in determination of unknown parameters.

The equations are of various types, such as Trigonometric equations, quadratic equations.

The system of equations are used to solve complex problems.

Let the cost of child ticket is $x

An adult ticket is twice the cost of a child's ticket.

Let the cost of adult ticket is $2x

The total amount Angela paid is $28 for two adult tickets and three children's tickets.

The equation that will be formed is

4x + 3x = 28

It can also be written as 3x + 2(2x) = 28.

Thanks!

Answers

/1/2/ sorry I don’t know how to do the straight line

An absolute value equation to satisfy the given solution set shown on a number line is -1/2 ≤ a ≤ 1/2.

What is magnitude and sign?

A number has both magnitude(its absolute value) and its sign(positive or negative).

Thus, for -5, the magnitude is 5, and sign is –ve.

Also, positive numbers > 0 > negative numbers.

In the number line we can clearly see that our possible values of a are in the range:

-1/2 ≤ a ≤ 1/2

And we need to find an absolute value equation such that this set is the set of possible solutions.
