Answer:
Rock travels about 8.2x²meters higher on the moon than on the Earth.
Step-by-step explanation:
Expression showing the height of a rock thrown into the air at Earth is,
f(x) = -9.8x² + 10x + 1.5
Similarly, expression showing the height of rock thrown on the moon is,
g(x) = -1.6x² + 10x + 1.5
Difference in the height of the rock thrown on moon = g(x) - f(x)
= (-1.6x² + 10x + 1.5) - ( -9.8x² + 10x + 1.5)
= -1.6x² + 9.8x² + 10x - 10x + 1.5 - 1.5
= 8.2x²
Therefore, rock travels about 8.2x²meters higher on the moon than on the Earth.

Step-by-step explanation:
Suppose y varies directly as x, and y = 7 when x = 2. Find x when y = 21.
Answer:
Step-by-step explanation:
y = k x X
7 = k x 2
7/2 = k...............1
hence y = 7/2x (substituting eq 1)
y = 21
therefore, x = 2y/7
x = 2 x 21
7
x = 2 x 3
x = 6
The required value of x is 6, when y =21 and y directly varies as x.
What is proportion?A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio.
Given that,
y directly varies as x,
Implies that,
y ∝ x
or y = k x (1)
When x = 2 and y = 7, from equation (1)
7 = k × 2
k = 7 / 2
To find the value of x when y = 21,
Substitute values of k = 7 /2 and y = 21 in equation (1),
21 = (7 / 2) × x
3 × 2 = x
x = 6
The value of x when y = 21, is 6.

what is the awser PLZ HELP!!!!!!!!!!!!!!!!!!!!!!!!!
I WILL REPORT U IF U PUT SOMETHING SILLY
Answer:
x = 7 1/3
Step-by-step explanation:
First, add 1/2 and 6
1/2 + 12/2 = 13/2 = 6 1/2
Our equation now:
13/2 over 3 - x - 3 over 2 = 0
Next, divide 13/2 by 3
13/2 divided by 3 = 13/6
Our equation now:
13/6 over 3 - (x - 3) over 2 = 0
Now, find common denominators and simplify
13/6 - ((x - 3) times 3) over 6 = 0
22 - 3x over 6 = 0
Multiply by six on both sides
22 - 3x = 0
Subtract 22 from both sides
-3x = -22
Divide by -1
3x = 22
Divide both sides of the equation by 3
x = 22/3
x = 7 1/3
Hope this helps!

Answer:

A motorboat heads upstream a distance of 24 miles on the Guadalupe River, whose current is flowing at 3 miles/hour. Which expression can represent the total time it takes to complete a round-trip up and back, where b is the speed of the boat in miles/hour?
Answer:
24/b-3 + 24/b+3
Step-by-step explanation:
For PLATO users!!!!
This expression represents the total time, Time = [tex]\frac{24}{b-3} + \frac{24}{b+3}[/tex]
What is distance?Distance is defined as the product of the speed and time.
Given,
b = the speed of the boat in miles/hour
let, effective speed upstream = (b+3)
effective speed downstream = (b-3)
∵Time = distance/ speed
Given that, upstream a distance of 24 miles
Time = [tex]\frac{24}{b-3} + \frac{24}{b+3}[/tex]
This expression represents the total time it takes to complete a round-trip up and back.

Nathalie has some quarters, dimes, and nickels. The ratio of the number of quarters to the number of dimes to the number of nickels that she has is $9:3:1$. The total value of these coins is $18.20. How many coins does Nathalie have?
Answer:
the answer is 91
Step-by-step explanation:
One group of 9 quarters, 3 dimes, and 1 nickel has the value of $9 \times 25 + 3 times 10 + 5=26 cents or 2.60 in total.
Since the coins she has are in this same ratio 9:3:1, we can split her coins up into groups of 9 quarters, 3 dimes, and 1 nickel, with each group having a value of 2.60
Because the total value of her coins is 18.20and 18.20\2.60=7, she has 7 of these groups of coins.
Each of these group contains 13 coins, so she has 7 times 13 = 91 coins in total.
Each of these group contains 13 coins, so she has total 91 coins.
What are nickles, dimes, quarters and cents?A dollar is further divided into some majorly used parts as:
A cent = 100th part of a dollar = $1/100 = $0.01
A nickle= 20th part of a dollar = $1/20 = $0.05
A dime = 10th part of a dollar = $1/10 = $0.10
A quarter = 4th part of a dollar = $1/4 = $0.25
One group of nine quarters, 3 dimes, and 1 nickel has the value of $9
25 + 3 times 10 + 5=26 cents or 2.60 in total.
Since the coins Nathalie has are in this same ratio 9:3:1, thus we can split her coins up into groups of 9 quarters, 3 dimes, and 1 nickel, with each group having a value of 2.60
Due to the total value of her coins is 18.20
18.20/2.60=7,
Hence, she has 7 of these groups of coins.
Each of these group contains 13 coins, so she has total ;
7 x 13 = 91 coins

Simplify the expression. 1.7 – 2.7 – 1.34 + 4.9 – 1.48
explain im lost
Answer:
0.08
Step-by-step explanation:
1.7 – 2.7 – 1.34 + 4.9 – 1.48
2.7
- 1.7 (subtract 1.7 from 2.7)
--------
-1.0 [2.7 is greater than 1.7 and 2.7 is negative(in the ques) , therefore 1.0 is negative]
-1.0-1.34
we know that (-) (-) is (+)
therefore add -1.34 with -1.0
1.34
+ 1.0
-----------
-2.34 [since 1.34 is greater and it is negative]
-2.34+4.9
we know that (-)(+) is (-)
therefore subtract -2.34 from 4.9
4.90 ← (we put zero so that we can subtract without getting confused)
- 2.34
------------
1.56 [1.56 is positive because 4.9 is greater and it is positive]
1.56-1.48
here, digit before the decimal point is same but after decimal point .56 is greater than .48 therefore subtract 1.48 from 1.56
1.56
- 1.48
-----------
0.08
therefore, 1.7 – 2.7 – 1.34 + 4.9 – 1.48 = 0.08
