The Extreme Rock Climbing Club planned a climbing expedition. The total cost was $3200, which was to be divided equally among the members going. Prior to the trip,10 members decided not to go. If the cost per person increased by $160, how many people went on the expedition?
Answer:
x = 25.
Step-by-step explanation:
Original cost per person:: 2000/x
Changed cost per person:: 2000/(x-5)
---------------------------
Equation:: changed - original = 20
2000/(x-5) - 2000/x = 20
2000x - 2000x + 2000*5 = 20x(x-5)
10000 = 20x^2-100
----
500 = x^2 - 5x
------------------
x^2 - 5x - 500 = 0
(x+20)*(x-25) = 0
-----
Only positive root makes sense ====> x = 25.

Which question can be answered using the information from the histogram?
***Be careful with this question. There is only one correct answer. Choose A, B, C, or D.
Pay attention to the intervals.
a. How many animals weigh 4.9 pounds?
b. How many animals weigh between 5 and 10 pounds?
C. How many animals weigh less than 8 pounds?
d. How many animals weigh at least 15 pounds?
mature
Answer:
d. How many animals weigh at least 15 pounds?
Step-by-step explanation:
The histogram displayed holds information about the number of animals who have a certain certain weight interval. Hence, answering questions about a point weight such as the number of animals whose weight is 4.9. This is a point value and such information given by the histogram.
Similarly, number of animals for intervals which aren't Cleary and explicly stated on the horizontal x - axis of the histogram cannot be determined by the histogram such as ; number of animals weighing less than 8 pounds and number of animals weighing between 5 and 10 pounds.
However, the number of animals weight less Than 15 pounds can be obtained from the histogram. This includes the sum give by the first, second and third bar. This is about (8 + 17 + 10) = 35 animals.

Miss Allen read for 3/4 of an hour less than the student who read the most. How long sis Miss Allen read for?
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Allen = \frac{3}{4}hr[/tex] less than the most hour
Required
Hours read by Miss Allen
The question is incomplete, as the hours read by each student is not given.
To solve this, I will assume that the longest hours read by a student is x.
So, the expression for Miss Allen will be:
[tex]Allen = x - \frac{3}{4}hr[/tex]
Assume that [tex]x = 1hr[/tex]
The expression becomes
[tex]Allen = 1hr - \frac{3}{4}hr[/tex]
Take LCM and solve
[tex]Allen =\frac{4 - 3}{4}hr[/tex]
[tex]Allen =\frac{1}{4}hr[/tex]
The expression shown is the cost a customer pays for an item,where c is the cost the store pays for the item and 0.85c is the 85% price increase the store adds to the item. Which expression is equivalent to c+0.85c
Answer:
D. 1.85c
Step-by-step explanation:
The expression shown is the cost a custom pays for an item, where c is the cost the store which expression is equivalent c+0.85c?
A. 0.15c B. 0.85c C. 1.15c D. 1.85c
Given:
c + 0.85c
c standing alone has a coefficients of 1
The coefficients of 0.85c is 0.85
The two terms have the same variable c
Add both terms together
c + 0.85c
= 1.85c
Therefore,
c + 0.85c = 1.85c
D. 1.85c

Answer:
solution given:
Area of triangle ABC=½b×h=½×18×21=189km²
Area of square DEFG=l²=9²=81km²
Area of rectangle DHIJ=l×b=4×13=52km²
Total area =189+81+52=322 square kilometers.
Answer:
[tex] \rm\displaystyle A _{ \text{total}} = 322 {km}^{2} [/tex]
Step-by-step explanation:
refer the attachment
we have a triangle,a rectangle and a square
in order to figure out the area of the total figure we need to figure out the area the attached figure first
Triangle:the triangle has a base of 18 km and a height of 13+6+2=21km
thus,
the area of the triangle is
[tex] \displaystyle \frac{1}{2} \times 18 km\times 21km[/tex]
reduce fraction:
[tex] \displaystyle 9 km\times 21km[/tex]
simplify multiplication:
[tex] \displaystyle 189 km ^{2} [/tex]
Rectangle:the rectangle has a length of 13km and a width of 4km
thus,
the area of the rectangle is
[tex] \displaystyle 13km \times 4km[/tex]
simplify multiplication:
[tex] \displaystyle {52km}^{2} [/tex]
Square:the length of every sides of the square is 9km
thus,
the area of the square is
[tex] \displaystyle {(9km)}^{2} [/tex]
simplify square:
[tex] \displaystyle {81km}^{2} [/tex]
Area-total:[tex] \rm\displaystyle A _{ \text{total}} = A_{ \text{triangle}} + A_{ \text{rectangle}} + A_{ \text{square}}[/tex]
substitute:
[tex] \rm\displaystyle A _{ \text{total}} = 189 {km}^{2} + 52 {km}^{2} + 81 {km}^{2} [/tex]
simplify addition:
[tex] \rm\displaystyle A _{ \text{total}} = 322 {km}^{2} [/tex]

Answer:
495 ft²
Step-by-step explanation:
To answer this, you need to subtract the area of the rhombus from the area of the square.
SQUARE:
A = bh
25x25=625
RHOMBUS:
A = bh
13 x 10 = 130
625 - 130 = 495

Which expression uses the distributive property to represent the sum of 72 + 24?
Answer:
a+b
Step-by-step explanation:
or any letter as long as it has the plus sign
The required expression for the given property is 8(9 + 3).
What is distributive property?The distributive property for the product of a sum of numbers to other numbers states that it is equivalent to the sum of individual products. It can be written as a(b + c) = ab + ac.
The given expression is 72 + 24
In distributive form it can be written as,
GCF of 72 and 24 is 8.
Then, 72 = 8 × 9 and 24 = 8 × 3
Now, the given expression can be rewritten as below,
8 × 9 + 8 × 3
Take 8 as common to get,
8(9 + 3)
Hence, the expression that represents the distributive property is 8(9 + 3).
