Answer:
Rate in still water = 48 mph.
Rate of current = 14 mph.
Step-by-step explanation:
Let the rate in still water be x and rate of the current be y miles per hour.
Upstream:
x - y = 102/3
Downstream:
x + y = 186/3
Adding the 2 equations
2x = 102/3 + 186/3 = 34 + 62
2x = 96
x = 48 mph.
So 48 - y = 34
y = 48 - 34 = 14 mph.

yo can get answer
solve the inequality please
Answer:
The solution is 4 >/= -21
4 is greater than or equal to negative 21
Step-by-step explanation:
7x + 4 >/= 7(x - 3)
We'll start by distributing the y7 to the items in parentheses
7x + 4 >/= 7x - 21
Subtract 7x from both sides
4 >/= -21

Answer:
Landon's purchase: p +5g = 17.55Lesley's purchase: 4p +2g = 13.50pretzel: $1.80granola bar: $3.15Step-by-step explanation:
The equation representing either purchase will multiply the number of items by their cost, for each item, and show the total as the cost of the purchase. Here, p is defined as the cost of a pretzel; g is defined as the cost of a granola bar.
Landon's purchase
1 pretzel + 5 bars will cost 1p +5g
That cost is 17.55, so the equation is ...
p +5g = 17.55
Lesley's purchase
4 pretzels + 2 gars will cost 4p +2g
That cost is 13.50, so the equation is ...
4p +2g = 13.50
__
To solve, you can subtract the second equation from 4 times the first:
4(p +5g) -(4p +2g) = 4(17.55) -(13.50)
18g = 56.70 . . . . collect terms
g = 3.15 . . . . . . . . divide by 18
Then the cost of a pretzel can be found using the first equation.
p + 5(3.15) = 17.55
p = 1.80
The cost of a pretzel is $1.80; the cost of a granola bar is $3.15.

A politician claims that 20% of the millions of votes cast for his opponent are fraudulent. To test this claim, an investigator collects a random sample of 90 ballots and contacts the voters whose names appear on the ballots to determine if each ballot is in fact fraudulent. Use a normal approximation to find the probability that less than 10 of the selected ballots turn out to be fraudulent, assuming the politician's claim is correct.
Answer:
"0.0125" is the right solution.
Step-by-step explanation:
The given values are:
Random sample,
n = 90
Claims,
p = 20%
or,
= 0.20
By using normal approximation, we get
⇒ [tex]\mu = np[/tex]
On substituting the values, we get
⇒ [tex]=90\times 0.20[/tex]
⇒ [tex]=18[/tex]
Now,
The standard deviation will be:
⇒ [tex]\sigma=\sqrt{np(1-p)}[/tex]
On putting the above given values, we get
⇒ [tex]=\sqrt{90\times 0.20\times (1-0.20)}[/tex]
⇒ [tex]=\sqrt{18\times 0.8}[/tex]
⇒ [tex]=\sqrt{14.4}[/tex]
⇒ [tex]=3.7947[/tex]
hence,
By using the continuity correction or the z-table, we get
⇒ [tex]P(x < 10) = P(x < 9.5)[/tex]
⇒ [tex]P(x < 10) = P(\frac{x-\mu}{\sigma} -\frac{9.5-18}{3.7947} )[/tex]
⇒ [tex]P(x < 10) = P(Z < -2.24)[/tex]
From table,
⇒ [tex]P(x < 10) = 0.0125[/tex]

What is the solution to this system of equations?
x − 2y = 15
2x + 4y = -18
A. x = 1, y = -6
B. x = 1, y = -7
C. x = 3, y = -6
D. x = 3, y = -7
Answer:
C. x = 3, y = -6 is the answer.
Step-by-step explanation:
1. Isolate x for x = 2y = 15 -> x = 15 + 2y
2. Substitute x = 15 + 2y -> [2 (15 + 2y) + 4y = -18]
3. Simplify -> [30 + 8y = -18)
4. Isolate y for 30 + 8y = -18 -> y = -6
5. For x = 15 + 2y, substitute y = -6 -> x = 15 + 2(-6)
So, x = 3 and y = -6 are the solutions to this system of equations.

Solve the following system of equations using the elimination method.
5x + y = 9
Answer:
x= -1/5y+9/5
Step-by-step explanation:
5x+y=9
Step 1
First you need to add -y to both sides, basically subtracting y
5x+y-y= 9-y
Step 2
Divide both sides by 5, or multiply by 1/5. You want to do this because to cancel out 5, so you multiply the reciprocal, or divide the constant.
1/5*5x=-y+9/5
Then, you will get the answer
Hope this helps, sorry if it is wrong, I am just 4th grade :(

Which describes how the figure below was transformed?
Answer: Rotation
Step-by-step explanation: This is a rotation because the figure is rotated 90°. This is not a translation because it isn't moved to a different position. This is not a reflection because it isn't mirrored. This is not a dilation because the size didn't change. Therefor, it is a Rotation, because this figure was rotated 90°

P varies inversely with the square of Q. When Q is 8, P 9. Find the value of P when Q is 3.
Answer:
P
[tex] \alpha [/tex]
1/q²
P=k/Q²
K=P×Q²
Where P=9
Q=8
K=?
K=9×8²
K=9×64
K=573
So where K= 573
Q=3
P=?
P=K/Q²
P=573/3²
P=573/9
P=63.67
