Answer:

Option D is the correct choice.

Step-by-step explanation:

We are provided angle of elevations of two artifacts buried beneath the ground and we are asked to find distance between these two elevations.

We will find distance between these elevations by taking the difference of two.

35:\frac{4}{7}--8:\frac{2}{7}

35:\frac{4}{7}+8:\frac{2}{7}=43:\frac{6}{7}

Since we know that distance is always positive so option A is incorrect.

Therefore, option D is the correct choice and distance between these two elevations is 43:\frac{6}{7}.

Answer:

The correct option is D.

Step-by-step explanation:

It is given that an archaeologist discovered two artifacts buried beneath the ground.

Elevation of first artifact = -8\frac{2}{7}

Elevation of second artifact = 35\frac{4}{7}

We need to find the distance between these two elevations.

Distance = Elevation of first artifact - Elevation of second artifact

Distance=-8\frac{2}{7}-(35\frac{4}{7})

Distance=-(8+\frac{2}{7})-(35+\frac{4}{7})

Distance=-8-\frac{2}{7}-35-\frac{4}{7}

On further simplification we get

Distance=-43-\frac{6}{7}

Distance=-(43+\frac{6}{7})

Distance=-43\frac{6}{7}

Distance can not be negative. So, find the absolute value.

Distance=|-43\frac{6}{7}|

Distance=|43\frac{6}{7}|

Therefore, the correct option is D.

Is 92 1/2 pounds equivalent to 1,480 ounces
kow [346]
Hi there!

Since

16 ounces = 1 pound,

We should divide 1480 by 16 and see if it equals 92.5.

1480 ÷ 16 = 92.5
92.5 = 92.5

Answer:
Yes.

Hope this helps!

The mean of the data set is 15.What number is missing? 9,12,16,18,23
maxonik [38]

The number 12 is missing in the data set.

<u>Step-by-step explanation</u>:

  • The numbers are 9,12,16,18,23.
  • The missing number is assumed to be 'x'

Mean = Sum of the integers / Total number of integers.

15 = (9+12+16+18+23+x) / 6

15 = (78+x) / 6

90 = 78+x

x = 90-78

x = 12

Julio started biking to the park traveling 8 mph, after some time the bike got a flat so Julio walked the rest of the way, trave
USPshnik [31]

Answer:

Julio travel <u>3 hours</u> by biking and <u>4 hours</u> by walking.

Step-by-step explanation:

Given:

Julio started biking to the park traveling 8 mph, after some time the bike got a flat so Julio walked the rest of the way, traveling 7 mph.

If the total trip to the park took 7 hours and it was 52 miles away.

Now, to find the time Julio travel at each speed.

The speed travelled by the bike = 8 mph.

The speed travelled by the walking = 7 mph.

Let the time Julio travel with bike be x.

And the time Julio travel by walking be y.

As, given Julio started biking to the park traveling, after some time the bike got a flat so Julio walked the rest of the way,

Thus, the total time taken:

x+y=7

y=7-x\ \ \ .......(1)

So, the distance travelled by bike:

Speed × time

8\times x=8x

And, the distance travelled by walking:

Speed × time

7\times y=7y

Now, the total distance travelled by Julio:

8x+7y=52

Substituting the value of x from equation (1) we get:

8x+7(7-x)=52

8x+49-7x=52\\\\x+49=52

<em>Subtracting both sides by 49 we get:</em>

x=3.

<em>The time Julio travelled with bike = 3 hours.</em>

Now, to get the time Julio travelled by walking by substituting the value of x:

y=7-x\\\\y=7-3\\\\y=4\ hours.

<em>The time Julio travelled by walking = 4 hours.</em>

Therefore, Julio travel 3 hours by biking and 4 hours by walking.
