Answer:

First turn any mixed numbers into improper fractions. 1 3/4 would be 7/4. Becuase you multiply the whole number by the denominator and then add the numerator.

So now you have 7/4 divided by 2/5. Whenever you divide, you flip the 2nd fraction upside down... known as the reciprocal. And after that you multiply the first number by the upside down 2nd number.

So now you have 7/4 X 5/2. When multiplying, just multiply the numerators across and the denominators across. As your answer, you get 35/8 or 4 3/8.

Complete question:

At the beginning of the day the stock market goes down 30 3/4 points and stays at this level for most of the day. At the end of the day the stock market  goes up 100 1/2 points from the low at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the​ day?

Answer:

The total change in the stock market is [tex]69\frac{3}{4}[/tex]

Step-by-step explanation:

Given;

the stock market at the beginning of the day =  30 3/4 points

the stock market at the end of the day = 100 1/2 points

The total change in the stock market from the beginning of the day to the end of the​ day is given by;

100 1/2 points - 30 3/4 points

[tex]= (100 -30) + (\frac{1}{2} -\frac{3}{4} )\\\\= 70 + (-\frac{1}{4} )\\\\= 70 - \frac{1}{4}\\\\= 69\frac{3}{4}[/tex]

Therefore, the total change in the stock market is [tex]69\frac{3}{4}[/tex]

Answer:D

Step-by-step explanation: times the 10 by the amount of hours they did on saturday which is $50. Subtract $50 from the $80 the total and the answer is $30, divide 30 by 10 and thats 3 the amount of hours that they worked on sunday. 10(x+5)=80 x=3 (3+5)=8 10(8)=80

Answer:

A

Step-by-step explanation:

You can plug in the x and y coordinates of the points to check which one is right.

The easiest point to start with is (0, 6).

[tex]A) 6=6*1.5^0\\B) 6=0.67^0\\C) 6=4*1.5^0\\D) 6=6*0.67^0[/tex]

Any number raised to the power of 0 is 1, so we can replace all of the exponents with 1.

[tex]A) 6=6\\B) 6=1\\C) 6=4\\D) 6=6[/tex]

That means we can immediately rule out B and C, since 6 clearly does not equal 1 or 4.

But since we still don't have our answer, we can plug in another point. Once again, you want to start with low, easy numbers, so let's plug in (1, 9).

[tex]A) 9=6*1.5^1\\D) 9=6*0.67^1[/tex]

Any number raised to the power of 1 is the same number:

[tex]A) 9=6*1.5\\D) 9=6*0.67[/tex]

Now we can multiply out both sides:

[tex]A) 9=9\\D)9=4[/tex]

Once again, it becomes immediately clear that D does not work, and A is therefore the correct equation.

Answer:

Step-by-step explanation:

Let say the following:

p = number of points

We know that they scored the same number of points in Game 1 and Game 2.

But in Game 3, they scored 6 points less than Game 1 and Game 2.

Therefore,

Game 1 = p

Game 2 = p

Game 3 =  p - 6

To find the average you use the following formula:

Number of points / number of games = average

Basically,

(Game 1 + Game 2 + Game 3 ) / 3 = 63

So substitute the equations we made earlier and you get:

[tex]\frac{Game 1 + Game 2 + Game 3}{3} = 63\\\frac{p + p + (p - 6)}{3} = 63[/tex]

After this you just want to solve for "p"

Multiply both sides by 3 to get rid of the fraction:

p + p + (p - 6) = 63 x 3 = 189

3p - 6 = 189

Add 6 to both sides.

3p = 189 + 6 = 195

Divide both sides by 3

p = 195/3 = 65

So now we know p = 65 points. Substitute this back into our equations for each game:

Game 1 = p  , Game 1 = 65 points

Game 2 = p , Game 2 = 65 points

Game 3 = p - 6 , Game 3 = 65 - 6 = 59 points

The amount of wrapping paper he use is 62.4 square inches

The formula for calculating the total surface area is expressed as:

Area = 4(area of triangle)

Find the area of the triangle

A = 0.5(6)(5.2)

A =3(5.2)

A = 15.6 square inches

TSA = 4(15.6)
TSA = 62.4 square inches

Hence the amount of wrapping paper he uses is 62.4 square inches

Answer:

2

Step-by-step explanation:

The last number is 2

You calculate this by the only way the mean can be 4 is if the 3 numbers= up to 12. so 9 + 1=10 and if were looking for 12 we need 2 more so 2.

10 + 2=12

When dealing with mean you calculate the sum of all the number(check) then divided by the total of numbers so 3

12 divided by 3=4 and 4= your mean

Hope it helps have a great day:)

Answer:

The area needed to be painted is approximately 301.44 square inches.

Step-by-step explanation:

The shape of a donut is represented by two concentrical circles, whose area is described by the following formula:

[tex]A =A_{g}-A_{s}[/tex] (Eq. 1)

Where:

[tex]A[/tex] - Total area of the donut, measured in squared inches.

[tex]A_{g}[/tex] - Area of the greater circle, measured in square inches.

[tex]A_{l}[/tex] - Area of the lesser circle, measured in square inches.

By using the definition of the area of the circle, we expand the equation above:

[tex]A = \frac{\pi}{4}\cdot D^{2}_{ext} - A_{s}[/tex] (Eq. 1b)

If we know that [tex]\pi = 3.14[/tex], [tex]D_{ext} = 22\,in[/tex] and [tex]A_{s} = 78.5\,in^{2}[/tex], the area needed to be painted is:

[tex]A = \frac{(3.14)\cdot (22\,in)^{2}}{4}-78.5\,in^{2}[/tex]

[tex]A \approx 301.44\,in^{2}[/tex]

The area needed to be painted is approximately 301.44 square inches.

Answer: x = -5 -z/y or x= -5/y - z/y

Step-by-step explanation:

-5 = xy + z -- then you need to isolate the x, so subtract z from both sides

-5-z = xy -- then divide both sides by y

x= -5-z/y
