At midnight, the temperature in a city was 5 degrees Celsius. The temperature was dropping at a steady rate of 2 degrees Celsius per hour.

Write an inequality that represents t, the number of hours past midnight, when the temperature was colder than -4 degrees Celsius. Explain or show your reasoning.
Show all the values of t that make your inequality true on a number line, like the one shown below.
A number line with the numbers negative 4 through 10, in increments of 2, indicated.

Answers

Answer 1

Answer:

(5-2t)<-4

Step-by-step explanation:

The temperature is 5 °C at midnight, and it is dropping at a speed of 2 °C each hour. If it's past midnight, the temperature will be t degrees after t hours ( 5 - 2t ). If the temperature is below - 4 ℃, the inequality can be  ( 5-2t ) - 4

Answers

Answer:

x = 11.5, y = -5.5.

As an ordered pair this is (11.5, -5.5).

Step-by-step explanation:

2x+4y=1               Multiply this by 3:

3x+5y=7               Multiply this by -2.

6x + 12y = 3

-6x - 10y = -14       Adding these 2 equations:

0 + 2y = -11.

y = -11/2

y = -5.5.

Now plug this into the first equation:

2x + 4(-5.5) = 1

2x = 1 + 22

x = 23/2

x = 11.5.

Christy spent 25 of her money on a shirt. She has $21.75 left. How much did she spend on the shirt?

A. $8.70
B. $7.25
C. $14.50
D. $29​

Answers

Christ spent a total amount of $ 14.50 on the shirt.

Finding the amount spent on the shirt

Here we use the linear equation concept to solve the problem.

Since we do not know the amount that Christ has assume that with a variable and form a linear equation using the data given.

Now solve the resultant equation for the value of the variable and find the amount spent by Christ on the shirt as given below

Here we have

Christy spent 2/5 of her money on a shirt.

She has $21.75 left

Let 'x' be the amount that Christy has

From the data,

Christy spent 2/5 of her money on a shirt.  

Amount spent by Christy = 2/5 of x = 2x/5

Remaining amount = x - 2x/5

From the data,

Chrisy is left with $ 21.75

=> x - 2x/5 = 21.75

=> 3x/5 = 21.75

=> 3x = 108.75

=> x = 36.25

Amount the that she spent 2x/5 = 2 (36.25)/5 = 14.50

Therefore,

Christ spent a total amount of $ 14.50 on the shirt.

A shark is swimming 42 feet below sea level. If the angle of depression from a boat on the water to the shark is 23°, what is the horizontal distance between the boat and the shark? Show your work to receive full credit. Round to the nearest hundredth if necessary. ​

Answers

Answer:

BC ≈ 98.95 feet

Step-by-step explanation:

From the figure attached,

A shark is swimming 42 feet below sea level at point A and a boat on the water is at point C.

If the angle of depression from the coat to shark is 23°,

tan(23°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(23°) = [tex]\frac{AB}{BC}[/tex]

BC = [tex]\frac{AB}{\text{tan}(23)}[/tex]

BC = 98.947

How many pounds are in 6 tons, 200 pounds

Answers

Answer:

there are 12000 pounds in 6 tons

There are 12,200 pounds in 6 tons, 200 pounds .

To convert tons to pounds, we need to multiply the number of tons by the conversion factor of 2,000 pounds per ton .

A ton, also referred to as a short ton, is a unit of weight equal to 2,000 pounds .

Given that there are 6 tons and 200 pounds, we can calculate the total weight in pounds as follows :

6 tons * 2,000 pounds/ton + 200 pounds = 12,000 pounds + 200 pounds = 12,200 pounds .

Therefore, there are 12,200 pounds in 6 tons, 200 pounds .

How many pounds of $1.75/lb trail mix should a grocer combine with 3 lb of $3.75/lb trail mix to get $2.95/lb trail mix? I WILL GIVE BRAINLIEST. PLLLLS!!!

The grocer should combine 2 pounds of $1.75/lb trail mix with 3 pounds of $3.75/lb trail mix to get 5 pounds of $2.95/lb trail mix.

What is an expression?

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.

Let's assume that the grocer needs to combine x pounds of $1.75/lb trail mix to the 3 lb of $3.75/lb trail mix.

To find out how many pounds of $1.75/lb trail mix are needed, we can use the following equation:

$1.75x + $3.75(3) = $2.95(x + 3)

Simplifying the equation, we get:

$1.75x + $11.25 = $2.95x + $8.85

Subtracting $1.75x from both sides, we get:

$11.25 = $1.20x + $8.85

Subtracting $8.85 from both sides, we get:

$2.40 = $1.20x

Dividing both sides by $1.20, we get:

x = 2

Therefore, the grocer should combine 2 pounds of $1.75/lb trail mix with 3 pounds of $3.75/lb trail mix to get 5 pounds of $2.95/lb trail mix.
