Answer:
[tex]Height = 2.5[/tex]
Step-by-step explanation:
Given
[tex]Volume = 35[/tex]
[tex]Length =7[/tex]
[tex]Base=4 cm[/tex]
Required
Determine the height
The volume is calculated as:
[tex]Volume = Height * Base\ Area[/tex]
Since, it has a triangular cross-section, the expression becomes:
[tex]Volume = Height * \frac{1}{2} * Base * Length[/tex]
So, we have:
[tex]35 = Height * \frac{1}{2} * 4 * 7[/tex]
[tex]35 = Height * 14[/tex]
[tex]Height = 35/14[/tex]
[tex]Height = 2.5[/tex]

Find the RANGE for the function f(x) = -4x - 9 if D = {1/2 ,0}
Answer:
-11, and -9 is the range for 1/2 and 0 respectively
Step-by-step explanation:
find the missing lengths of the sides
Answer:
a=9, c=19
Step-by-step explanation:
Aight so basically in 30, 60, 90 triangles there is a formula for the sides
the hypotenuse(the longest side)=2a
The tiny side (the smallest side)=a
and the middle child =[tex]a\sqrt{3}[/tex]
Based on that we see that a is 9
and since c=2a then it's 18

lim x>infinity x^2 - ln(2/x)/3x^2 + 2x
Answer:
1/3
Step-by-step explanation:
[tex][x^2 - ln(2/x)]/[3x^2 + 2x]\\[/tex]
∞/∞
[tex]\frac{d}{dx}[x^2-ln(2/x)] =2x+\frac{1}{x}\\ \frac{d}{dx}[3x^2+2x]=6x+2\\\frac{2x+\frac{1}{x}}{6x+2}[/tex]
Also ∞/∞
[tex]\frac{d}{dx}[2x+\frac{1}{x}]=2-1/x^2\\\frac{d}{dx}[6x+2]=6\\\\[/tex]
[tex]\lim_{x \to \infty} \frac{2-\frac{1}{x^2} }{6}\\=\frac{2}{6} \\=\frac{1}{3}[/tex]

Find the value of the expression a--b* for a = 2 and b= 1
Answer:
3
Step-by-step explanation:
Given the expression a --b
Given that
a = 2
b = 1
Substitute into the expression
a--b
= 2 --1
= 2 - (-1)
= 2 + 1
= 3
Hence the required value is 3

Answer:
C
Step-by-step explanation:
Evolution is where organisms have developed over time from simple to complex. Therefore we can rule out D because older rock layers should have simple organisms and A because new rock layers should have more complex organisms. The previous organisms will be unlike those of today, therefore the correct answer is C.

What is 566.8 divided by 52
Step-by-step explanation:
Step 1
The first step is to set up our division problem with the divisor on the left side and the dividend on the right side, like we have it below:
5 5 2
Step 2
We can work out that the divisor (5) goes into the first digit of the dividend (5), 1 time(s). Now we know that, we can put 1 at the top:
1
5 5 2
Step 3
If we multiply the divisor by the result in the previous step (5 x 1 = 5), we can now add that answer below the dividend:
1
5 5 2
5
Step 4
Next, we will subtract the result from the previous step from the second digit of the dividend (5 - 5 = 0) and write that answer below:
1
5 5 2
- 5
0
Step 5
Move the second digit of the dividend (2) down like so:
1
5 5 2
- 5
2
Step 6
The divisor (5) goes into the bottom number (2), 0 time(s), so we can put 0 on top:
1 0
5 5 2
- 5
2
Step 7
If we multiply the divisor by the result in the previous step (5 x 0 = 0), we can now add that answer below the dividend:
1 0
5 5 2
- 5
2
0
Step 8
Next, we will subtract the result from the previous step from the third digit of the dividend (2 - 0 = 2) and write that answer below:

Good Luck Studying ^-^
please help find the perimeter
Answer:
Perimeter of the given figure = 28 units
Step-by-step explanation:
Perimeter of the given figure = Length of AB + Length of BC + Length of CD + Length of DE + Length of EF + Length of FG + Length of GH + Length of AH
Length of AB = 4.5 units
Length of BC = 2 units
Length of CD = 2 units
Length of DE = 4 units
Length of EF = 5.5 units
Length of FG = 1.5 units
Length of HG = 1 units
Length of AH = 7.5 units
Perimeter of ABCDEFGH = 4.5 + 2 + 2 + 4 + 5.5 + 1.5 + 1 + 7.5
= 28 units

Two boys A and B are a two diametrically opposite points on a circle. at one instant the two start running on the circle
Step-by-step explanation:
let the distance travel by both be a&b
a has a distance of d1 like wise b
speed=distanc/time
d1=2v
d2=4v
total distance
d1+d2=180
2v+4v=180
6v=180
v=30
d1=2*30
d1=60
d2=4*20
d2=120
now start u get u starting
not that there meet at same point so now calculate the time they will trave in there various direction
time=distance/velocity
but they but move at a standard velocity
Answer:
is this the full question: Two boys A and B are at two diametrically opposite points on a circle. At one instant the two start running on the circle; A anticlockwise with constant speed v and B clockwise with constant speed 2v. In 2 minutes, they pass each other for the first time. How much later will they pass each other for the second time?
if yes than this is the answer:-
A speed = v
B speed = 2v
Time to meet = 2 minutes
d= pi r ( distance they have to run to meet)
they are running towards each other.
(2v+v)
speed = 3v
d=rt
pi*r = 3v*2
r= 6v/pi
circumference = 2* pi*r
=2*pi*(6v/pi)
=12v
...
Now distance to travel to meet = 12v
speed = 3v
t=d/r
t= 12v/3v
t= 4 minutes
I hope this helps a little bit.
