60 / 3 = 20.  25 / 5 = 5.  This means that the you get 20cm by 5 cm.  However, you must do the sum again with the new dimensions.  20 / 3 = 6.6666666. 5 / 5 = 1.  The final dimensions of the map are 6.66666cm (6 1/3 cm) by 1cm.

Bill's golf bag contains 9 white golf balls, 6 yellow golf balls, 1 orange golf ball, and 1 pink golf ball. Without looking, Tim
BaLLatris [955]

Answer:

The correct answer is 0.0330 and the events are independent.

Step-by-step explanation:

Total number of balls in Bill's golf bag = 17

Let A be the event of drawing a white ball and B be the event of drawing an orange ball.

Number of white balls Bill has in his bag is 9.

Probability of the event A in the first draw = \frac{9}{17}

Number of orange ball in Bill's bag is 1.

Probability of event B in the second draw = \frac{1}{16}

Thus total probability for Tim to tee off with a white ball and putt with an orange ball = \frac{9}{272} = 0.0330

The above events are independent on each other.

Westkost [7]

Answer: The best estimate for the amount of money she saves to buy clothes = $ 562.5

Step-by-step explanation:

Given: Breanna saves 75% of her earnings to buy new school clothes.

Earnings for Breanna = $ 750

The amount of money she saves to buy clothes = 75% of 750

= 0.75 x  750   [75%= 0.75]

= $ 562.5

Hence, the best estimate for the amount of money she saves to buy clothes =  $ 562.5

A ball is thrown into the air with an upward velocity of 36 ft/s. It’s height h in feet after t seconds is given by the function
777dan777 [17]

Answer:

Time taken for the ball to hit the ground back = 3.08 s

Step-by-step explanation:

h(t)= -16t² + 48t + 4

when will rhe object come back to hit rhe ground?

When the ball is at the level.of the ground, h(t) = 0.

0 = -16t² + 48t + 4

-16t² + 48t + 4 = 0

Solving the quadratic equation

t = 3.08 s or t = -0.08 s

Since the time cannot be negative,

Time taken for the ball to hit the ground back = 3.08 s

Hope this Helps!!!

Show 46/200 on the hundredths grid. then write the fractions as a demical
SSSSS [86.1K]
If we want to has 100 in the denominator we have to divide numerator and denominator by 2. Then total value of fraction doesnt change.
\frac{46}{200}= \frac{46:2}{200:2}= \frac{23}{100}
Now read the fraction, its 23 hundreds, now just write as decimal, so, 0.23
