Answer:

Part A $150.00

Part B $140.00 because you would do 35 x 4 = 140.

Part C, He will have $17 left over. You would take 167 - 140 = 17

Question 5, The would have gathered $150 because you would take 30 x 5 = 150.

The measurement of the radius of the end of a log is found to be 9 inches, with a possible error of 1/2 inch. Use differentials

enot [183]

Answer:

$\pm 9in^2$

Step-by-step explanation:

We are given that

Radius of end of a log, r= 9 in

Error, $\Delta r=\pm 1/2$ in

We have to find the error in computing the area of the end of the log by using differential.

Area of end of the log, A= $pi r^2$

$\frac{dA}{dr}=2\pi r$

$\frac{dA}{dr}=2\pi (9)=18\pi in^2$

Now,

Approximate error in area

$dA=\frac{dA}{dr}(\Delta r)$

Using the values

$dA=18\pi (\pm 1/2)$

$\Delta A\approx dA=\pm 9in^2$

Hence, the possible propagated error in computing the area of the end of the log $=\pm 9in^2$

-8y=24

We want to isolate y to get the value of 1y. Divide both sides by -8
y= -3

Final answer: y=-3

12.
This is the associative property of addition (D).
It states that when adding three terms, the sum is equal no matter the grouping (parentheses).

At the movie theatre, child admission is S5.20 and adult admission is $8.30. On Tuesday, 156 tickets were sold for a total sales

Annette [7]

Answer:

So, 89 Adult tickets were sold.

Step-by-step explanation:

So, we first name our variables, say, a for number of adult tickets, and c for child tickets.

Then we write our system of equations, first the total $ sale:

5.2c + 8.3a = 1087.10

Then we write the 2nd equation, the total number of tickets:

c + a = 156

Now, we can solve the system:

We do have different methods, let's to by subsitution.

make some change to the 2nd equation, to make c the subject: c = 156 - a

Now we plug that into the 1st equation:

5.2(156 - a) + 8.3a = 1087.10

811.2 - 5.2a + 8.3a = 1087.10

811.2 + 3.1a = 1087.10

3.1a = 275.9

a = 89
