Harriet traveled 1,249 meters by bicycle. Then she traveled 2,987 meters by boat and 66,245 meters by hot air balloon. How many meters did Harriet travel altogether?

Answers

Answer 1
Answer:

Answer: 70,481 meters

Step-by-step explanation:

Given: The distance traveled by bicycle = 1,249 meters

The distance traveled by boat = 2,987 meters

The distance traveled by hot air balloon =  66,245 meters

The distance traveled by Harriet altogether is given by :-

D=1,249+2,987+66,245\text{ meters}\n\n\Rightarrow D=70,481\text{ meters}

Hence, the distance traveled by Harriet altogether is 70,481 meters.
Answer 2
Answer:

Answer:

70,481 meters.

Step-by-step explanation:

We have been given that Harriet traveled 1,249 meters by bicycle. Then she traveled 2,987 meters by boat and 66,245 meters by hot air balloon.

To find the total distance traveled by Harriet we will add the distance traveled by bicycle, boat and hot air balloon.

\text{Total distance traveled by Harriet}=\text{1,249 meters + 2,987 meters + 66,245 meters}

\text{Total distance traveled by Harriet}=\text{70,481 meters}

Therefore, Harriet traveled 70,481 meters altogether.

At a country concert, the ratio of the number of boys to the number of girls is 2:7. If there are 250 more girls than boys, how many boys are at the concert?

Answers

Boys : Girls = 2:7
let the no. of boys be x
so no of girls = 250+x
so, x:(250+x) = 2:7
x/(250+x) = 2/7
7x = 500+2x
7x-2x = 500
x = 500/5 =100

in a standard deck of t2 playing cards, there are 4 aces, 4 kings, 4 queens, and 4 Jacks. All other cards have number values. the kings, queens, and Jack's are called face cards. You are dealt 2 cards in a sequence. calculate the probability of being dealt a 3 and then a 10. write your answer as a decimal to the nearest hundredth​

Answers

Answer:

0.01

Step-by-step explanation:

Assuming the deck is the national playing deck with 52 cards.

Your probability of getting a 3 from the entire deck is 4/52. This number is the same for 10.

To get the probability of pulling a 3 and a 10 afterwards, you must multiply these two fractions (you're expecting a lower percentage).

4/52 * 4/52 = 0.0059

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

The fractions are:

8/7, 1 2/5, x, 1 2/3, 2

Or

8/7, 7/5, x, 5/3, 2

1.142, 1.4, x, 1.667, 2

x could be

x = 1 1/6 = 1.166

Thus, the value of x could be 1 and one-sixth, or StartFraction 8 Over 5 EndFraction option (A) and (B) are correct.
