A penguin population increases by 60%, representing an increase of 3840 penguins. How many penguins were there before the increase?
Answer:
2304
Step-by-step explanation:
The equation for this is 3840*0.6 which equals 2304. And to check, we can divide 2304 by 0.6, and that gives us 3840. I hope this helps! :)

Step-by-step explanation:
Barney was driving at 25 mph. A car pulls out 30 ft ahead of him. The coefficient of friction, f, is 0.7. Which statement is true? A Barney hits the car. B Barney stops less than a foot from the car. C Barney misses the car by 3 ft. D Barney's skid marks measure 23 ft.
Answer:
B Barney stops less than a foot from the car.
Step-by-step explanation:
From the information given:
The initial speed of barney [tex]v_o[/tex] = 25 mph
Coefficient of friction [tex]\mu[/tex] = 0.7
Recall that
1 mph = 0.447 m/s
Then
[tex]v_o[/tex] = 25 × 0.447 m/s
[tex]v_o[/tex] = 11.175 m/s
The force of friction acting on the barney is expressed as:
[tex]F = \mu N \\ \\ F = \mu mg[/tex]
[tex]ma = \mu mg[/tex]
[tex]a = \mu g[/tex]
a = 0.7 × 9.8 m/s
a = 6.86 m/s²
Since the force acts in an opposite direction to the motion of Barney, Thus the acceleration must also be negative.
a = -6.86 m/s²
Now;
Suppose Barney stops after traveling a distance (s), so that the final speed is zero.
Then;
Using the kinematic equation;
[tex]v^2 - v_o^2 = 2as[/tex]
[tex]0 - (11.17)^2 = 2 \times (-6.86) s[/tex]
[tex]-124.76 = -13.72 s[/tex]
[tex]s = \dfrac{124.76}{13.72}[/tex]
s = 9.09 m
Recall that;
1 m = 3.28 ft
So;
s = 9.09 m = 9.09 × 3.28 ft
s = 29.81 ft
∴
The distance traveled by the Barney is 29.81 ft which implies that Barney stops less than a foot from the car.

You plan to go snowboarding this weekend in Pennsylvania. The resort charges $15.75 per hour in addition to a $25 deposit to rent a snowboard. Write and solve a linear equation to find the total cost to rent the snowboard from 8:30 a.m. to 12:30 p.m.
Answer:
$88 in total
Step-by-step explanation:
x = number of hours
y = total cost to rent the snowboard.
$25 is already guaranteed
25 + 15.75x = y
since it is 4 hours from 8:30 a.m. to 12:30 a.m. you put 4 into x.
25+15.75(4) = y
88 = y
What is the measure of the vertex angle
Answer:
Vertex angle = 124°
Step-by-step explanation:
m<BAC = m<BCA (base angles of isosceles ∆ are congruent)
7x + 1 = 5x + 9
Collect like terms
7x - 5x = -1 + 9
2x = 8
divide both sides by 2
x = 4
Vertex angle = 180 - ((7x + 1) + (5x + 9)) (sum of triangle)
Plug in the value of x
Vertex angle = 180 - ((7*4 + 1) + (5*4 + 9))
Vertex angle = 180 - (29 + 29)
Vertex angle = 124°
A triangle has interior angles equal to 51 and 42 degrees.Find the interior angle x
Answer:
Angle x would be 87 degrees.
Step-by-step explanation:
Angles inside of a triangle add up to 180 degrees. So 51+42=93 and if you subtract 93 from 180, you get 87.

what is the slope of the line passing through he points ( 4, 3 ) and (1,-2 )?
Answer:
[tex]1\frac{2}{3}[/tex]
Step-by-step explanation:
The slope of a line is the change in a line, or the, [tex]\frac{rise}{run}[/tex] in a line. One can find the slope of a line using the formula,
[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Substitute in the known points and solve,
[tex](4, 3), (1, -2)[/tex]
[tex]\frac{(-2)-(3)}{(1)-(4)}\\[/tex]
Simplify,
[tex]\frac{-5}{-3}[/tex]
[tex]\frac{5}{3}\\\\1\frac{2}{3}[/tex]

the cost of 12 pencils is rupees 37 4 by 5 find the cost of one pencil
Answer:
Cost of 12 pencils = 37 4/5 = 189/5
Cost of 1 pencil = 189/5 ÷ 12
= 189/5 x 1/12 = 189/60 = 63/20 = 3 3/20
So required answer is 3 3/20

The price of a man's shirt went from $15 to $20. What was the percent of increase of the price of the shirt? A. 25% A. , 25%, B. 3313% B. , 33 and 1 over 3 percent, C. 20% C. , 20%, D. None of these D. , none of these,
Answer: 33 1/3%
Step-by-step explanation:
Percentage increase of the shirt will be calculated as:
= Price Increase / Old price × 100%
Price Increase = $20 - $15 = $5
Old price = $15
Percent increase = Price Increase / Old price × 100%
= 5/15 × 100
= 1/3 × 100
= 33 1/3%
Answer:
it would be -25% because 15 is less than 20

P is a rectangle length 40cm and width x cm the length of q is 25%more than the length of p
Answer:
the answer
the ratio x:y is 25:18
Step-by-step explanation:
we know that
the length of Q is 25% more than the length of p
so
length Q=1.25*40--------> 50 cm
the area of Q is 10% less than the area of p
Area Q=50*y
Area P=40*x
so
50*y=0.90*[40*x]---------> 50*y=36*x-------> x/y=50/36---> 25/18

What is the value of x?
Enter your answer in the box.
x =
Answer:
x = 5
Step-by-step explanation:
The interior angles of a triangle always have to add up to 180 degrees.
This means you can form an equation with the three angles you have:
(10x - 4) + (8x + 3) + 91 = 180
Then, solve:
[tex]10x-4+8x+3+91=180[/tex]
combine like terms
[tex]18x+90=180[/tex]
subtract 90 from both sides
[tex]18x = 90[/tex]
divide both sides by 18
[tex]x = 5[/tex]

SOME ONEEE PLZZ HELPP MEEEE
Answer:
2.5
Step-by-step explanation:
The minimum value is the minimum y-value a function includes. In this case, since you can see the function is periodic (it repeats itself periodically, hence periodic) and the smallest y-value the function encounters is 2.5 (doesn't go below this value), the minimum y-value is 2.5. I hope this made sense. If not, feel free to let me know.

Please help
9514 1404 393
Answer:
(x, y) = (7, -1)
Step-by-step explanation:
The expression for x makes it easy to use that for substitution.
3(-7y) +y = 20
-20y = 20 . . . . . collect terms
y = -1 . . . . . . . . . divide by -20
-7(-1) = x = 7 . . . use y in the second equation to find x
The solution is (x, y) = (7, -1).
