Answer:
Runner 1 = 9th place
Runner 2 = 10th place
Runner 3 = 11th place
Runner 4 = 12th place
Runner 5 = 13th place
Step-by-step explanation:
Given that:
Number of runners = 5
Total points scored = 55
Finishing spot for each runner (they finished one after the other)
Hence,
x, (x + 1), (x + 2), (x + 3), (x + 4)
x + x + 1 + x + 2 + x + 3 + x + 4 = 55
5x + 10 = 55
5x = 55 - 10
5x = 45
x = 9
Hence,
Runner 1 = 9th place
Runner 2 = 10th place
Runner 3 = 11th place
Runner 4 = 12th place
Runner 5 = 13th place

B. The typical value is greater in set A. The spread is greater in set B.
C. The typical value is greater in set B. The spread is greater in set A.
D. The typical value and the spread are both greater in set B.
Answer:
c. the typical value is greater in set b. the spread is greater in set a
Step-by-step explanation:
The typical value is greater in set A. The spread is greater in set B.
The correct answer is an option (B)
What is the typical vale?"It is the average value (mean) of the data"
What is spread of the data?"It is the measure of how far the values in a data set are away from the mean.""The simplest measure for the spread of the data is range of the data set."What is the range of the data?"It is the difference between maximum and minimum value."
For given example,
We can observe that the typical value for set A is between 7 and 8
and the typical value for the set is in between 4 to 5.
So, the typical value is greater in set A
The range of the set A is :
R = 9 - 6
R = 3
The range of the set B:
R = 7 - 0
R = 7
So, the spread is greater in set B.
Therefore, the typical value is greater in set A. The spread is greater in set B.
The correct answer is an option (B)

real
1 feet = 12 inches
5 feet = 60 inches
scale
3 inches = 20 feet
60 inches=
60/3 = 20
20*20= 400
therefore 5 feet tall equall 400 feet

What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The scale of the model is,
⇒ 3 inches = 20 feet
Now,
Since, The scale of the model is,
⇒ 3 inches = 20 feet
And, The model is 5 feet tall.
Since, 1 feet = 12 inches
So, 5 feet = 60 inches
Here, The scale of the model is,
⇒ 3 inches = 20 feet
So, The actual length of the building = 60 × 20/3
= 400 feet

Answer:
264 boxes of crayons
Step-by-step explanation:
HI there!
To solve this, first we have to find out how many classes there are in total to make this easier.
Since they’re giving crayons to grades K-2, That means 3 grades will be getting crayons. If there’s 4 classes in each grade, multiply 4 by 3 to find the total amount of classes, which is 12.
Now to find the total amount of crayons, we multiply 12 by 22 to find the total amount of crayons bought.
They need to buy 264 boxes of crayons.
Hope this helps!

Chanasia has 11.25 gallons of paint. She wants to use 2 5 of the paint to paint her living room. How many gallons of paint will Chanasia use?
Answer: 4.5 gallons
Step-by-step explanation:
From the question, Chanasia has 11.25 gallons of paint and she wants to use 2/5 of the paint to paint her living room.
The number of gallons of paint that Chanasia will use would be calculated by multiplying the fraction by the total gallons of paint. This will be:
= 2/5 × 11.25
= 0.4 × 11.25
= 4.5 gallons

The weights of 5 adult Chihuahuas recorded by a
veterinarian are listed below. What is the median weight
of the Chihuahuas?
2,850 g, 1,880 g, 1,530 g, 1,920 g, 2,850 g
A 2,850 g
B 1,920 g
c 2,206 g
D
1,530 g
Answer:
B. 1, 920
Step-by-step explanation:
To get the median, you order from lowest to highest.
So;
1, 530 , 1,880 , 1,920 , 2,850 , 2,850
Then you find the middle ground / the number in the middle. Since it's odd, all we have to do is look at the number directly in the middle. So the answer is B. 1, 920.

a group buys 6 hot dogs and 3 hamburgers for a total of $27.75. the hamburgers cost $1.75 more than a hot dog. what is he cost of the hamburger
Answer:
Cost of one hamburger = $4.25
Step-by-step explanation:
Let,
Cost of one hot dog = x
Cost of one hamburger = y
According to given statement;
6x + 3y = 27.75 Eqn 1
y = x + 1.75 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
6x + 3(x+1.75) = 27.75
6x + 3x + 5.25 = 27.75
9x = 27.75 - 5.25
9x = 22.50
Dividing both sides by 9
[tex]\frac{9x}{9}=\frac{22.50}{9}\\x=2.50[/tex]
Putting x=2.50 in Eqn 2
y = 2.50 + 1.75
y = 4.25
Hence,
Cost of one hamburger = $4.25

The size of a pancake is measured by its radius. The corner shop charges $12 for a 3-inch personal pancake. The largest pancake is a 6-inch pancake that costs $20. How many times larger is the area of the largest pancake than the personal pancake? A. 2 B. 3 C. 4 D. 6
Answer:
C. 4
Step-by-step explanation:
A pancake is circular in shape
Hence, the area of a circle = πr²
HenceThe corner shop charges
a) $12 for a 3-inch personal pancake.
For personal pancake
r = 3 inches
πr² = π × 3²
= 28.274333882 square inches
= 28.3 square inches
b) The largest pancake is a 6-inch pancake that costs $20.
For Largest pancakes
r = 6 inches
πr² = π × 6²
= 113.09733553 square inches
Approximately = 113.1 square inches
How many times larger is the area of the largest pancake than the personal pancake?
This is calculated as :
Largest pancake/Personal pancake
= 113.1/28.3
3.9964664311 inches
Approximately = 4
Option C is the correct option

The Montoya family and the Cooper family are seeing a movie together in the theater. At the concession stand, Mr. Montoya paid $20 for 3 large popcorns and 1 large drink that his family will share. Mrs. Cooper bought 3 large popcorns and 3 large drinks and paid $30. How much does each item cost?
Answer:
Both items cost $5 each
Step-by-step explanation:
Given data
let popcorn be x
and drink be y
Mr. Montoya paid $20 for 3 large popcorns and 1 large drink
so
3x+y= 20-------------1
and
Mrs. Cooper bought 3 large popcorns and 3 large drinks and paid $30
so
3x+3y= 30----------------2
solve 1 and 2 above
3x+y= 20
y= 20-3x
put y= 20-3x in eqn 2
3x+3(20-3x)= 30
3x+60-9x= 30
collect like terms
3x-9x= 30-60
-6x= -30
x= 30/6
x= $5
put x= 5 in y= 20-3x
y= 20-3*5
y= 20-15
y= $5
