Answer:
the options were not copied correctly, option B could be correct but it is missing the division signs:
B. p / 100 = 2.4 / 15
the percentage of medicine used in 1 hour:
p / 100 = (15 - 12.6) / 15 = 2.4 / 15
p / 100 = 0.16
p = 0.16 x 100 = 16%
another option could be C but it would be missing the multiplication signs:
C. p x 15 = 100 x 2.4
p x 15 = 240
p = 240 / 15 = 16%

A force of 52 N acts upon a 4 kg block sitting on the ground. Calculate the acceleration of the object.
The acceleration of the block is 13 m/sec².
What is Acceleration?Acceleration is defined as the rate of change of velocity with respect to time, It is a vector quantity with units of m/sec².
Force = 52 N
Mass of the block = 4kg
Acceleration =?
The formula for the force applied to any object is given by
F = mass * Acceleration
Substituting the values
52 = 4 * Acceleration
Acceleration = 52 / 4 = 13 m/sec².
Therefore, The acceleration of the block is 13 m/sec².

Answer:
8. The length of the longest side is 40 ⇒ H
Step-by-step explanation:
8. In the given figure
∵ The triangle has two equal sides 2x + 12 and 5x - 9
→ Equate their expressions to find the value of x
∴ 5x - 9 = 2x + 12
→ Add 9 to both sides
∵ 5x - 9 + 9 = 2x + 12 + 9
∴ 5x = 2x + 21
→ Subtract 2x from both sides
∵ 5x - 2x = 2x - 2x + 21
∴ 3x = 21
→ Divide both sides by 3 to find x
∵ [tex]\frac{3x}{3}[/tex] = [tex]\frac{21}{3}[/tex]
∴ x = 7
∵ The longest side is 6x - 2
→ Substitute the value of x in its expression to find its length
∴ The longest side = 6(7) - 2 = 42 - 2
∴ The longest side = 40
∴ The length of the longest side is 40

[tex] \rm Solve \: for \: b: \\ \rm \longrightarrow A = \dfrac{1}{2} bh \\ \\ \rm A = \dfrac{bh}{2} \: is \: equivalen t \: to \: \dfrac{bh}{2} = A: \\ \rm \longrightarrow \dfrac{bh}{2} = A \\ \\ \rm Divide \: both \: sides \: by \: \dfrac{h}{2} : \\

Answer:
b in terms of A and h will be:
[tex] \boxed{ \rm{b = \frac{2A}{h} }}[/tex]
Step-by-step explanation:
This is basically the formula for finding the area(A) of the triangle in terms of b and h. We have to solve for b in terms of A and h.
[tex] \rm{A = \dfrac{1}{2} bh}[/tex]
Multiplying 2 in the LHS. This is shift because inverse of division is multiplication.
[tex] \rm{2A = bh}[/tex]
Dividing h from both sides,

What is the probability of being born in May or on the 30th of any month?
Answer: 41/365
Step-by-step explanation:
The probability of being born in May is 31/365 (May has 31 days and there are 365 days in a year).
The probability of being born on the 30th of the month is 11/365 (11 months have at least 30 days). However, since we have included May 30 in our MAy probability, we need to use the probability of 10/365.
Add the two probabilities together, and the probability of being born in May or on the 30th is 31/365 + 10/365 = 41/365.

Graph: y-3=1/2(x+2)
Answer:
Step-by-step explanation:
First you need to find the Slope Intercept form or find the point and slope.
The point is: (-2,3)
and the slope is: 1/2
y - 3 = 1/2(x + 2)
y - 3 = 1/2x + 1
y = 1/2x + 1 + 3
y = 1/2x + 4
Slope intercept form: y = 1/2x + 4

Which is one characteristic of hurricanes?
occur mostly inland
create widespread damage
last for a short amount of time
gain strength after passing over land
9514 1404 393
Answer:
create widespread damage
Step-by-step explanation:
Hurricanes are tropical storms that generally develop over the Atlantic ocean. The ones of concern in the US are the ones that follow a westward path. They generally gain strength over water, and dissipate over land. They can last several days, though their movement generally means the worst impact in a given area lasts only a matter of hours. (Clean-up may take months or years.)
Hurricanes are one of the largest of storm systems, so can cause widespread damage.

What is the y-value to the solution of y = 5x -4 and y = 2x + 8
Answer:
At the bottom!
Step-by-step explanation:
Put the two equations into the same standard form:
2x-y=8
-5x+2y=3
Now if you add the two equations up, guess what will happen?
You will "eliminate" the y variable, and only be left with the x variable.
Technically, you will get:
2x-y+2+28-5x+29+2y=8+23
-3x+20y=11
-3x=11
Write the equation of the line that goes through (-3.9, -1.4) and is PERPENDICULAR to 6x + 2y = 9
9514 1404 393
Answer:
10x -30y = 3
Step-by-step explanation:
In general form, you can start by swapping the x- and y-coefficients, negating one of them. To find the new constant for the equation, substitute the values for the given point
2x -6y = 2(-3.9) -6(-1.4)
2x -6y = 0.6
Multiplying by 5 will make the numbers be integers, so will put the equation in standard form.
10x -30y = 3
