Answer:

She has descended a total of 18 feet from the top to her friend.

Step-by-step explanation:

Anna is 26 ft. high on a rock-climbing wall.

She descends to the 15-foot mark,means she come to a height of $26-15=11$ feet and rests.

Then climbs down until she reaches her friend, who is 8 feet from the ground.

So, she climbs down $15-8=7$ feet more.

Hence, in total Anna has descended $11+7=18$ feet

The answer : She has descended a total of 18 feet from the top to her friend.

In one baseball season, Nolan hit twice the difference of the number of home runs Mrs. Davis hit and 6. Altogether, they hit 18

Alborosie

Answer:

Nolan hitted 8 home runs

Step-by-step explanation:

Let's call the number of home runs that Nolan hitted by N, and that Davis hitted by D.

So, we can write the following equations:

N = 2 * (D - 6)

N + D = 18

Now we can solve the system of equations, using the value of N from the first equation in the second one:

2 * (D - 6) + D = 18

2*D - 12 + D = 18

3*D = 30

D = 10

Now we find N:

N + D = 18

N + 10 = 18

N = 8

So we have that Nolan hitted 8 home runs.

Let X denote the total snowfall in the Twin Cities in December of a given year, measured in centimeters. The five-number summary

Gre4nikov [31]

Answer:

Concept: Caclulating Standard Variables

We have a five number summary which is more than enough information to calculate our mean.
The mean is the sum of all the numbers divided by the nth number of numbers.
Note that we can only find a rough estimation not the EXACT value
We do (min +max + 2(Q1+median+Q3))/8
Now let's plug in our values!
(0+85.3+2(8.4+17.4+30.9))/8
Which gives us option B
