Answer:

The value of y is 110 degrees

Step-by-step explanation:

-we know that the Angle sum property of a quadrilateral is 360 degrees.

- so we can find the 4th angle

- and find y through the linear pair method.

The fourth angle=70 degrees

And y=180-70=110(Linear pair)

I need help with this distributive property question.

Elena-2011 [213]

The answer is -1. You multiply the 1/4 with the 5x and equal it to 3 multiplied by 5 and have gotten 15x, then multiply the 3 with the 2, as apart of the parentheses. Lasty you just leave the -9 on the side and solve the equation.

PLEASE HELP

NeTakaya

Answer:

12/12

Step-by-step explanation:

I would say simply perform the division already indicated.

(16 in)/(12 h) = 16/12 in/h = 4/3 in/h

Alternatively, divide the given rate by 1. The form 12/12 gives you the same thing as above:

(16 in)/(12 h)/(12/12) = (16/12) in/h = 4/3 in/h

If the cost, C(x), for manufacturing x units of a certain product is given by

Diano4ka-milaya [45]

Answer:

99 units.

Step-by-step explanation:

The cost function for manufacturing <em>x</em> units of a certain product is:

$C(x)=x^2-15x+34$

We want to find the number of units manufactured at a cost of $8350. Therefore:

$8350=x^2-15x+34$

Subtract 8350 from both sides:

$x^2-15x-8316=0$

This equation can be a bit difficult to factor, if even possible, so we can use the quadratic formula:

$\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

In this case, a = 1, b = -15, and c = -8316. Thus:

$\displaystyle x=\frac{-(-15)\pm\sqrt{(-15)^2-4(1)(-8316)}}{2(1)}$

Simplify:

$\displaystyle x=\frac{15\pm\sqrt{33489}}{2}$

Evaluate:

$\displaystyle x=\frac{15\pm183}{2}$

Therefore, our solutions are:

$\displaystyle x=\frac{15+183}{2}=99\text{ and } x=\frac{15-183}{2}=-84$

We cannot produce negative items, so we can ignore the second answer.

Therefore, for a cost of $8350, 99 items are being produced.

Discuss how you will use number sense to help plan a trip to your state capital. In your response, include the numbers that woul

nordsb [41]

To plan a trip to your state capital, you need the following numbers

The number of available routes
The distance
The speed limit
Time

Assume you're travelling by road, you need to highlight the number of routes between your state and the state capital.

The number of routes is a natural number (i.e. minimum of 1 e.g. 6, 8, 1). Because it is a natural number, the number of routes can never be 0.

Next is to determine the distance to the state capital through each route. In most cases, the distance between places are positive rational or irrational numbers (however, they can be approximated to natural numbers).

The speed limit on each route will also help in planning the trip. Speed limits are always represented as natural numbers. When you know the speed limit (and the distance), you can use that to predict how long (i.e. the time) the trip will take. The formula to use is:

$Speed = \frac{Distance}{Time}$

Make time the subject

$Time= \frac{Distance}{Speed }$

The value of time can be estimated/approximated as a natural number.

In addition to the previous number, you may also need the following numbers

The liters of fuel to use
The amount of fuel per liter

The essence of place value in these number (especially the numbers with decimal points) is to get an estimated value.
