Leah flips a coin, and then she spins a spinner with 3 equal sections colored red, green, and blue. What is the probability that
the coin flips heads, and
the spinner lands on either red or blue?
Enter your answer as a percentage, to the nearest percent.

Answers

Answer 1

Answer:

1/3 ! i think?

Step-by-step explanation:

there's a 1/2 chance it lands on heads and a 2/3 chance it lands on red or blue and 1/2 x 2/3 is 1/3

Answer 2

The probability that the coin flips heads, and the spinner lands on either red or blue is 1 by 3.

Calculation of the probability:

Since Leah flips a coin, and then she spins a spinner with 3 equal sections colored red, green, and blue.

Since there is half chance for heads and 2 by 3 for landing on red or blue

So, the probability should be

[tex]= 1/2 \times 2/3 \\\\= 1/3[/tex]

Hence, The probability that the coin flips heads, and the spinner lands on either red or blue is 1 by 3.

A bakery sells taro, red bean and green tea pues. 65% of the pies are taro pies. 40% of the remaining pies are red bean pies. How many pies are there altogether?​

Answers

Answer: 1,800 pies in total

Step-by-step explanation:

A key detail missing is that there are 378 green tea pies.

Assuming the total number of pies is x.

65% of this is taro pies. This leaves 35% to be red bean pies and green tea pies.

If 40% of this remaining 35% are red bean pies, that means that 60% are green tea pies.

= 35% * 60%

= 21% of the total are green tea pies

There are 378 green tea pies and this is 21% of the total number of pies.

378 = 0.21 * x

x = 378 / 0.21

= 1,800 pies in total

the scale on a map is 1:25000. how many km on the ground is represented by 6cm on the map?

Answers

Given:

The scale on a map is 1:25000.

To find:

How many km on the ground is represented by 6cm on the map?

Solution:

Let x be the km on the ground.

We know that,

1 km = 1000 m

1 m = 100 cm

So,

1 km = 100,000 cm

x km = 100,000x cm

The scale on a map is 1:25000. It means the ratio of map and ground is equal to 1:25000.

[tex]\dfrac{1}{25000}=\dfrac{6}{100,000x}[/tex]

[tex]\dfrac{100,000x}{25000}=6[/tex]

[tex]4x=6[/tex]

[tex]x=\dfrac{6}{4}[/tex]

[tex]x=1.5[/tex]

Therefore, 1.5 km on the ground is represented by 6cm on the map.
