Step-by-step explanation:
a gazelle can run away from a cheetah with a speed of 35.0 m/s. if the average gazelle has a mass of 40.00 kg, what is the gazelles kinetic energy,in kilojoules?HELPPP
9514 1404 393
Answer:
24.5 kJ
Step-by-step explanation:
Kinetic energy is given by the formula ...
KE = 1/2mv² . . . . . where m = mass
The gazelle's kinetic energy is ...
KE = 1/2(40 kg)(35 m/s)² . . . . . where m is meters
= 24,500 J . . . . . . 1 J = 1 kg·m²/s²
= 24.5 kJ . . . . . . . 1000 J = 1 kJ

8 Black pencils cost 15e cach and coloured
pencils cost 2lc cach. Ir 24 pencils cost
$4,02, how many of them were black (Hint
let there be + black pencils. Thus there are
24 – x coloured pencils. Work in cents.)
of
Answer:
17 black pencils
Step-by-step explanation:
Cost of black pencils; 15 cents each
Cost of colored pencils; 21 cents each
We are told that 24 pencils cost $4.02 = 402 cents
Let black pencils be x and let colored pencils be y.
Thus;
x + y = 24 - - - (eq 1)
Also,
15x + 21y = 402 - - - (eq 2)
From eq 1, y = 24 - x
Thus putting it in eq 2 gives;
15x + 21(24 - x) = 402
15x + 504 - 21x = 402
504 - 402 = 6x
x = 102/6
x = 17

Please answer as quickly as you can! ♥ Find two possible dimensions for a cylinder that has a volume of 64π cm³.
Answer:
Possible dimensions are [tex]r=4\,\,cm\,,\,h=4\,\,cm[/tex] and [tex]h=16\,\,cm\,,\,r=2\,\,cm[/tex]
Step-by-step explanation:
Given:
Volume of a cylinder is [tex]64\pi\,\,cm^3[/tex]
To find: Dimensions of a cylinder
Solution:
Let [tex]r,h[/tex] denote height of a cylinder.
Volume of a cylinder = [tex]\pi r^2h[/tex]
Therefore,
[tex]64\pi=\pi r^2h\\64=r^2h\\4^2\,4=r^2h[/tex]
One possible dimension can be [tex]r=4\,\,cm\,,\,h=4\,\,cm[/tex].
Also, [tex]64=r^2h[/tex] can be written as [tex]16(2^2)=hr^2[/tex]
So, another possible dimension can be [tex]h=16\,\,cm\,,\,r=2\,\,cm[/tex]

y = –x + 4 in standard form
Answer:
x-y=4
Step-by-step explanation:
y=x−4
The standard form of a linear equation is
Ax+By=C.
Rewrite the equation with the sides flipped.
x−4=y
Move all terms containing variables to the left side of the equation.
Tap for more steps...
x−y−4=0 Add 4
to both sides of the equation.
x−y=4

8. Find the slope of the line that contains the
following points:
b. (6, -2) and (-3, 1).
Answer:
slope = [tex]-\frac{1}{3}[/tex]
Step-by-step explanation:
1) Find the slope with the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] (in which [tex]m[/tex] represents the slope). The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and the [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. Thus, substitute the x and y values of the given points (6, -2) and (-3, 1) into the appropriate places in the formula and solve:
[tex]m = \frac{(1)-(-2)}{(-3)-(6)} \\m = \frac{1+2}{-3-6} \\m = \frac{3}{-9} \\m = -\frac{1}{3 }[/tex]
Thus, the slope is [tex]-\frac{1}{3}[/tex].

Use the square root property to solve: 5x^2+8 =133
Please help
Answer:
x = ± 5Step-by-step explanation:
See the steps
5x^2+8 = 1335x^2 = 133 - 85x^2 = 125x^2 = 125/5x^2 = 25√x² = √25x = ± 5Answer:
x=5
x=−5
Step-by-step explanation:
5x^2+8 =133
Subtract 8 from both sides.
5x^2=133−8
Subtract 8 from 133 to get 125.
5x^2=125
Divide both sides by 5.
x^2=125/5
Divide 125 by 5 to get 25.
x^2=25
Take the square root of both sides of the equation.
x=5
x=−5

What is the minimum velocity attained on the interval 0
Answer:
0.630
Step-by-step explanation:
Simply evaluating, we get v (0) = 1, v (0.31831) = 0.630, v (2) = 1.566. Thus, the minimum velocity over the interval [ 0, 2] is 0.630.

Michael reads 12 pages of a book in 18 minutes, 8 pages in 12 minutes,and 20 pages in 30 minutes. Is this a proportional relationship? If so, what is the constant of proportionality? What does it represent? Write an equation to represent this situation.
Answer:
y = 2/3xStep-by-step explanation:
Reading rate is y pages per x minutes and proportional relationship formula is:
y = kxThe coefficient is:
k = y/xLet's verify if the given numbers fit into the same relationship:
12/18 = 2/38/12 = 2/320/30 = 2/3We confirm all same and it means k = 2/3
Required equation is:
y = 2/3xThis represents that Michael reads 2 pages per 3 minutes and for x minutes he reads 2/3x pages
The sum of four consecutive integers is 170. Write an equation that can be used to find the smallest integer.
Answer:
The Equation to find the smallest integer =
4x + 6 = 170
The smallest integer = First integer = x = 41
Step-by-step explanation:
Four consecutive integers is represented by:
First Integer = x
Second Integer = x + 1
Third Integer = x + 2
Fourth Integer = x + 3
The sum of four consecutive integers is 170.
x + x + 1 + x + 2 + x + 3 = 170
The Equation to find the smallest integer =
4x + 6 = 170
4x = 170 - 6
4x = 164
x = 164/4
x = 41
Therefore:
The Equation to find the smallest integer =
4x + 6 = 170
The smallest integer = First integer = x = 41

Some money was invested at 12% interested for 2 years. If the interest was $21, how much was invested?
Answer:
$87.5 was invested
Step-by-step explanation:
10.5 is 12% of 87.5, so if the money was in the bank for 2 years, we would have to do 10.5*2 which is 21, and that's how much money was gained from the investment.

What is the solution to -2(2x - 3)= 4 - (3x + 5)?
Answer:
x=7
Step-by-step explanation:
expand -2(2x-3): -4x+6
expand 4-(3x-5): -3x-1
it's now -4x+6=-3x-1
subtract 6 from both sides
-4x+6-6=-3x-1-6
simplify
-4x=-3x-7
add 3x to both sides
-4x+3x=-3x-7+3x
simplify
-x=-7
divide both sides by -1
[tex]\frac{-x}{-1}[/tex]=\ [tex]\frac{-7}{-1}[/tex]
simplify
x=7

Please help me, I'm giving away the rest of my points for this 2 part question..
for the second part the answer choices are
A: Right
B: Obtuse
C: Isosceles
D: Equilateral
Answer:
First part
angle ABC=94 degrees
angle BCD=25 degrees
angle ACB=43 degrees
Second part
C) isosceles and obtuse because angle ABC is greater than 90 degrees and angle ACB=angle CAB
Step-by-step explanation:
All triangles contain 180 degrees.
Triangles ADB and CDB are congruent because side-angle-side theorem.
Since angle ABD=133 degrees, angle CBD=133 degrees because corresponding angles of congruent triangles are equal.
angle ABC=360-133-133=94 degrees
angle BCD=180-133-22=25 degrees
angle ACB=(180-94)/2=43
