The temperature at dawn is -6°F but by noon it is 22°F. What is the difference in
temperatures?
O -16°F
O-28°F
O 16°F
O 28°F

Answers

Answer 1

Answer: 28 degrees farenheit

Step-by-step explanation: add 22 and 6 for the total of how many degrees -6 is from 22.

Answer 2

If the  temperature at dawn is -6°F but by noon it is 22°F.Then 28°F  is the difference in temperatures

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The temperature at dawn is -6°F

The temperature at dawn in afternoon is 22°F.

We need to find the difference in temperatures.

Difference is nothing but subtracting one number with another number.

Now subtract  -6°F from 22°F.

22°F-(-6°F)

Twenty two degree fahrenheit plus six degree fahrenheit

22°F+6°F

28°F

Hence there is 28°F in temperatures. Option D is correct.

Step-by-step explanation:

An equation to keep in mind is y=mx+b

m= \(\frac{y_{2}-y_{1} }{x_{2}- x_{1} }\)

Any two coordinates would be good for this formula

For example you could use (2, -4) and (3, -7)

(3, -7) would be your second coordinate

(2, -4) would be your first coordinate

-7 = \(y_{2}\)

3= \(x_{2}\)

-4= \(y_{1}\)

2= \(x_{1}\)

Put the values into the formula and solve

\(\frac{-7-(-4)}{3-2}\)= \(\frac{-7+4}{1}\) = \(\frac{-3}{1}\)= -3

m= -3

Now you have y=-3x +b

There are 2 ways to find b, but I will show the one that is the easiest to explain for me

1) substitute the x and y coordinates from one of the coordinates into the 'new' formula

I will be using the coordinate (2,-4)

y = -3x + b

-4 = - 3(2) +b

-4 = -6 +b

-4 +6 = -6 +6+b

2 = b

Your updated equation is y=-3x+2

The answer is the second option

Jane is saving money to buy a game. The game costs $20, and so far she has saved four-fifths of this cost. How much money has Jane saved?

Answers

Answer:

she has 16$ saved

Step-by-step explanation:

20 divided 5 = 4

4 fifths of 20 is 16

Answer: $16

To do this problem you need to first find out how much 1/5th of 20 is. Which we can do by multiplying 20 x 1/5 which will give us 4. Since $4 is 1/5 of the total amount and we need 4/5th this value, we can multiply 4 x 4 to get $16 saved in total.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given, √30

If we could make the perfect square factor of 30 then it will come out from the radical sign as,

√12 = √(4 × 3) = √(2² × 3) = 2√3

Therefore, the √30 cannot be simplified.

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?

Answers

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500
