TEA [102]3 years ago
6 0

Answer:

9. 40°

10. 50°

11. 270°

12. 310°

Step-by-step explanation:

m∠BPC = 40° because it is complementary to ∠APB, which is 50°.

Arc AB is 50° because it will be equal to the central angle, which is 50°.

Arc ADC is 270° because it will be equal to the central angle, which is 270°.

Arc ADB is 310° because it will be equal to the central angle, also 310°.

What is the constant of proportionality? 48= 4k
inna [77]

Answer:

The constant of proportionality is 12.

Step-by-step explanation:

Let's take a look at the formula give to us:

48=4k

First, we have to isolate the variable, K, by dividing 4 on both sides.

48/4=4/4 k

48/4=12

12=k

We can check the answer by plugging it back into the equation:

12*4=48

48=48

Hence, the variable k equals 12.

If the scale on a map is 1/4 in. = 50 miles, how many miles do 3 3/8 inches represent?
Korvikt [17]
Hey there Fish Girl!

So, if \left[\begin{array}{ccc}1/4 \end{array}\right] equals 50 miles, then we would do this multiplied by . . . . 

So, if we would want to go to 3 whole, we would then have to go to the number 3 of course. So then, we do \left[\begin{array}{ccc}4*3=12\end{array}\right] and then from this, we would have to multiply this my 50.

The reason to why we would have to do this is because 1/4 of a mile is 50, so then, sense we are trying to get to the number 3, then, from doing this,we would determine a figure out how many miles this would conclude to be.

\left[\begin{array}{ccc}12*50\end{array}\right]   =\left[\begin{array}{ccc}\boxed{\boxed{600}} \ so \ far!\end{array}\right]

So, now, we have covered 3 as a whole, then we would have to see how 3/8 and also 1/4 can relate to each other.

So, in this case,\boxed{\boxed{ \frac{3}{8} \ would \ be \ almost \ \boxed{half} \\ \ because \ it \ is \ almost  \frac{4}{8} }}

So, most likely, it would stay the same as it is, 1/4 because this is almost half to.

SO ALL WE WOULD NEED TO DO NOW IS TO ADD . . . . . 

\left[\begin{array}{ccc}\left[\begin{array}{ccc}\boxed{\boxed{600+50 \ or  \frac{1}{4}=650}} \end{array}\right]\end{array}\right]

YOUR CORRECT AND FINAL ANSWER TO THIS QUESTION WOULD BE. . . . 

\left[\begin{array}{ccc}650 \ miles\end{array}\right]

Hope this helps you fish Girl! :)

To approximate the number of bees in a hive, multiply the number of bees that leave the hive in one minute by 3 and divide by 0.
AlekseyPX

Answer:

There are about 5,357 bees in the hive

Step-by-step explanation:

Let

x ----->  the number of bees that leave the hive in one minute

y -----> the approximate number of bees in a hive

we know that

The formula to calculate the approximate number of bees in a hive is equal to

y=\frac{3x}{0.014}

For x=25

substitute

y=\frac{3(25)}{0.014}

y=5,357\ bees

therefore

There are about 5,357 bees in the hive
