we are given

The scale is

\frac{1}{2} inch=3miles

the distance from Happy Hill Park to Rainbow Valley Park is 4 1/2 inches

we can change it into rational form

and we get

=\frac{9}{2}inch

so, we can multiply both sides by 9

9*\frac{1}{2} inch=9*3miles

now, we can simplify it

\frac{9}{2} inch=27 miles

so, the actual distance between the two parks is 27 miles........Answer

Alborosie

Answer:

∠ BDA = 55° , ∠ BCA = 70°

Step-by-step explanation:

∠ BOA = 360° - 250° = 110° ( angles round a point )

The central angle is twice the angle on the circle, subtended on the same arc

∠ BDA = \frac{1}{2} ∠ BOA = \frac{1}{2} × 110° = 55°

OBCA is a tangent kite

Opposite angles sum to 180° , then

∠ BCA = 180° - ∠ BOA = 180° - 110° = 70°

tresset_1 [31]

The speed of Maglev train is 267 miles per hour.

Step-by-step explanation:

Given,

Speed of Maglev train = 430 kilometers per hour

We know that;

1 kilometer = 0.62 miles

Therefore,

430 kilometers = 0.62*430

430 kilometers = 266.6 miles

Rounding off to nearest whole number

430 kilometers = 267 miles

The speed of Maglev train is 267 miles per hour.

Ksenya-84 [330]

Answer:

x = 162 cards need to be dealt with

Step-by-step explanation:

Given:

- Estimation of likelyhood of next card to be queen, a king, or an ace:

                                  ( 64 - 0.2*x ) / ( 208 - x )

Find:

For what values of x is this likelihood greater than 70%?

Solution:

- Use the likely-hood estimation relation and set up the inequality as follows:

                                 ( 64 - 0.2*x ) / ( 208 - x ) > 0.7

                                 ( 64 - 0.2*x ) > 0.7*( 208 - x )

                                   64 - 0.2*x > 145.6 - 0.7*x

                                          0.5*x > 81.6

                                                 x > 163.2

- It would require 162 cards to be dealt with for the probability of next card being queen, a king, or an ace is greater than 70%
