Answer:

Part a) The temperature at noon was -3°F

Part b) The temperature at 3:00 pm was +2°F

Part c) The temperature at 11:00 pm was -6°F

Step-by-step explanation:

The complete question is

When Leo woke up he saw that the temperature was -8°F. By noon the temperature has increased 5°F. Part a) What was the temperature at noon?

Part b) By 3:00 pm, the temperature increased by another 5 degrees Fahrenheit was the temperature at 3:00 pm positive or negative?

Part c) By 11:00 pm, the temperature had dropped 8°F. Was the

temperature at 11:00 PM positive or negative? Explain.​

Part a) we know that

You can use a number line to adds the numbers

-8+5=-3°F

therefore

The temperature at noon was -3°F

Part b) we know that

the temperature increased by another 5 degrees

You can use a number line to adds the numbers

-3+5=+2°F

therefore

The temperature at 3:00 pm was +2°F

Part c) we know that

the temperature had dropped 8°F

You can use a number line to adds the numbers

2-8=-6°F

therefore

The temperature at 11:00 pm was -6°F

Explain (in words) what you would do to find the missing value in the equation. You do not find the missing number! Equation: ?
maks197457 [2]

Answer:

The missing value = 23\frac{1}{24}

Step-by-step explanation:

Given - Equation: ? + 59 5/8= 82 2/3

To find - Explain (in words) what you would do to find the missing value in

              the equation. You do not find the missing number.

Proof -

Let the missing number = x

So, the equation becomes x + 59\frac{5}{8} = 82\frac{2}{3}

⇒x = 82\frac{2}{3} - 59\frac{5}{8}

     = \frac{248}{3} - \frac{477}{8}

     = \frac{1984 - 1431}{24}

     = \frac{553}{24}

     = 23\frac{1}{24}

⇒x = 23\frac{1}{24}

∴ we get

The missing value = 23\frac{1}{24}

Explanation -

Here we have given the ? with addition of number that is equation to some number.

We just have to subtract the two numbers to find the missing value , as we do above.

Someone help me please
Gemiola [76]

Answer:

x=2\sqrt{6}

Step-by-step explanation:

Use the Pythagorean theorem:

a^2+b^2=c^2

a and b are the legs and c is the hypotenuse. Insert the values:

\sqrt{10}^2+\sqrt{14}^2=x^2

Simplify exponents using the rule \sqrt{x}^2=x :

10+14=x^2

Simplify addition:

24=x^2\\x^2=24

Find the square root:

\sqrt{x^2}=\sqrt{24}\\  x=\sqrt{24}

Simplify in radical form: Find a common factor of 24 that is a perfect square:

\sqrt{24}=\sqrt{4*6}

Separate:

\sqrt{4}*\sqrt{6}

Simplify:

2*\sqrt{6}\\x=2\sqrt{6}

Finito.

Shiny White dental insurance costs $258 per year. Approximately one-third of insured people need a filling, which averages $110
sveta [45]

Answer:

  about $145.33

Step-by-step explanation:

Consider a group of 15 customers. They will pay ...

  15 × $258 = $3870

in premiums each year.

One-third of those, 5 customers, will submit claims for fillings, so will cost the insurance company ...

  5 × $110 = $550

And 80% of them, 12 customers, will submit claims for preventive check-ups, so will cost the company ...

  12 × $95 = $1140

The net income from these 15 customers will be ...

  $3870 -550 -1140 = $2180

Then the average income per customer is this value divided by the 15 customers in the group:

  $2180/15 = $145.33

_____

<em>Alternate solution</em>

Above, we chose a number of customers that made 1/3 of them and 4/5 of them be whole numbers. You can also work with one premium and the probability of a claim:

  258 - (1/3)·110 - 0.80·95 = 145.33
