The approximate value of 九十√70 is 11.51, correct option is 11.51.

<h3>What is an approximation?</h3>

An approximation is anything that is similar, but not exactly equal, to something else.

Now, the value of 九 is given as 22/7 is 3.142

To the nearest hundredth, it can be written as 3.14

The value of +√70 is given as 8.366

To the nearest hundredth as 8.37

For the required value of the expression we can write,

九十√70

Put the value of 九 = 3.14

and value of √70 = 8.37

Putting values in expression we have,

九十√70 = 3.14 + 8.37

⇒九十√70 = 11.51

Hence,the approximate value of 九十√70 is 11.51.

So,the correct option is 11.51.

Which car can travel at the slowest rate? Plz help fast

grigory [225]

Answer:

Step-by-step explanation:

Let's find unit rate of each (number of miles traveled in 1 hour). For that we will divide the distance by time to get the unit rate.

Note: $rate=\frac{Distance}{Time}$

(A)

rate = $\frac{300}{4}=75$ mph (miles per hour)

(B)

rate = $\frac{450}{6}=75$ mph

(C)

rate = $\frac{750}{10}=75$ mph

(D)

rate = $\frac{800}{12}=66\frac{2}{3}$ mph

<u>As we can see, the first 3 rates are same, 75 mph, and the last one is $66\frac{2}{3}$ mph. So clearly, the last rate is the slowest.</u>

D is the right answer.

An ellipse has a center at the origin, a vertex along the major axis at (20, 0), and a focus at (16, 0). the equation of the ell

olga_2 [115]

If the center is at (0, 0) and the vertex is at (20, 0), then the distance, a, is the length from the center to the vertex, 20. The distance from the center to the focus is c. The distance from the center to the focus is 16, so c = 16. The formula we use to find the focus is $c^2=a^2-b^2$ . We have our c value and our a value, so we will sub in those to find b. $16^2=20^2-b^2$ and 256 = 400 - b^2. -b^2 = -144, so b = 12. There you go!
