John was 40" tall in 2008 and 46" tall in 2010. Dave was 53" tall in 2003 and 70" tall in 2007. Who is growing at
a faster rate? If each person keeps growing at the same rate, how tall can we expect each to be in 2011? Is this
a reasonable expectation?
Answer:
John is growing at a faster rate.
Step-by-step explanation:
John grew 6 inches in 2 years, while Dave grew 7 inches in 4 years. We can expect John to grow another 3 inches by 2011, making John 49 inches tall in 2011. We can expect Dave to grow about another 7 inches by 2011, since another 4 years has passed. This seems reasonable enough...
how does cheese spoil?
Answer:
Microbiological spoilage of cheese is one of the important reasons that render the nutritious and tasty cheese not only inedible but also a potential source of infection. The spoilage may be due to bacteria or fungi. The defect due to contamination may arise from the surface of the cheese showing visual and organoleptic changes or it may be hidden internally.
Answer:
Cheese: It smells like sour milk.
If you spot mold on hard cheese, it's generally safe to cut off the moldy part and eat the rest, since the spores likely will not have spread throughout the cheese. Another sign that cheese has gone bad is a smell or taste of spoiled, sour milk.

Jon and Lexi are playing a marble game. According to their rules, 4 points are awarded for each red marble collected and 3 points are awarded for each blue marble collected. Which expression represents Jon's total score if he has r red marbles and b blue marbles?
4r − 3b
2r − 3b
4r + 3b
7rb
Answer:
i believe the answer is 4r - 3b
Answer:
4r+3b
Step-by-step explanation:
4 red awarded = 4r
3 blue awarded = 3b
Score = 4r + 3b

Tickets for a high school football game cost $2.50 each if purchased in advance. They cost $3.75 each if bought at the gate on the day of the game. For a particular game , 250 tickets were sold at the gate. If the sales totaled $1750, how many tickets were sold in advance?
250*3.75=937.5
1750-937.5=812.5
812.5/2.5=325
325 tickets were sold in advance :)
Answer:
1,500 tickets were sold in advance.
Step-by-step explanation:
$ 1,750 - 250 tickets = 1,500 tickets

Analyze the following equation.
43 = k/99
Which math step will most efficiently solve the equation?
Add 99 to both sides of the equation.
Subtract 99 from both sides of the equation,
Multiply both sides of the equation by 99.
Divide both sides of the equation by 99.
Answer:
Multiply both sides by 99
Step-by-step explanation:

-6(x+2)=5(3x+6)
i wasn’t here when we did this
Answer:
x=-2
Step-by-step explanation:
-6(x+2)=5(3x+6)
-6x-12=15x+30 distribute the outside numbers
-6x=15x+42 add 12 on both sides
-21x = 42 subtract 15x on both sides
x=-2 divide by -21 on both sides.

In a normal distribution, what is the probability that a data value will fall above the
data value associated with a z-score of 0.15?
A 55.96%
B 53.98%
C 44.04%
D 46.02%
Answer: C 44.04%
Step-by-step explanation:
in a normal distribution,
P(Z>z)= 1-P(Z<z) (*)
Here , we need to find : P(Z>0.15)
By using (*) , P(Z>0.15)=1- P(Z<0.15)
= 1- 0.5596 [By p-value table]
= 0.4404
= 44.04% [multiply 100 to convert into percent]
∴ the probability that a data value will fall above the data value associated with a z-score of 0.15 = 44.0%
hence, correct option : C 44.04%

plzzzzzzzzzzzzzzz help me!!!!!!!
look at the screenshot
Answer:
Step-by-step explanation:
GH bisects ∠FGI.
So, ∠HGI =∠FGH
6x - 17 = 5x - 8 {Add 17 to both sides}
6x = 5x - 8 + 17
6x = 5x + 9 {Subtract 5x form both sides}
6x - 5x = 9
a) x = 9
b) ∠FGH = 5* 9 - 8
= 45 - 8
∠FGH = 37
c) ∠HGI = 6*9 - 17
= 54 - 17
∠HGI = 37
d) ∠FGI = ∠FGH + ∠HGI
= 37 + 37
∠FGI = 74
very simple

Can someone figure this out??
Answer:
x = 6 2/3
Step-by-step explanation:
We can use ratios to solve
x/4 = 15/9
Using cross products
9x = 4*15
9x = 60
Divide each side by 9
x = 60/9
x = 20/3
x = 6 2/3
Subtract 8 – (-2).

2x - 1y = -9
y = - 5 - 5x
Answer:
x = - 7 and y = 30
Step-by-step explanation:
2x - y = -9
subtract 2x from either side
-y = -9 - 2x
divide either side by -1
y = 9 + 2x
Plug in 9 + 2x for y
9 + 2x = -5 - 5x
Add 5 to either side and subtract 2x from either side
14 = -2x
divide either side by -2
-7 = x
plug in -7 for x in one of the equations
y = -5 - ( 5 x -7 )
y = -5 - ( - 35)
y = -5 + 35
y = 30
plug in x and y
30 = -5 - ( 5 x -7)
30 = -5 - (-35)
30 = -5 + 35
30 = 30
Answer:
B. −19

In a group of 28 students, 12 study both Art and Biology.
12 study Biology but not Art.
4 study neither subject.
Given that a randomly selected student studies Art, what is the probability the student studies Art and Biology?
Answer:
100%
Step-by-step explanation:
Use conditional probability:
P(B | A) = P(B and A) / P(A)
P(B | A) = (12/28) / P(A)
We need to find the probability that a student studies art.
P(A or B) = P(A) + P(B) − P(A and B)
24/28 = P(A) + (12+12)/28 − 12/28
P(A) = 12/28
P(B | A) = (12/28) / (12/28)
P(B | A) = 1
What this means is that all of the students who study art also study biology.
