Answer:

Step-by-step explanation:
9x + 25 + x + 5 = 180
Add numbers = (25 + 5 = 30)
9x + 30 + x = 180
Combine like terms = (9x + x = 10x)
10x + 30 = 180
Subtract 30 from each side (10x + 30 - 30 = 180 - 30)
10x = 150
Divide 10 from each side (10x/10 = 150/10)
x = 15

The radius of a sphere is increasing at a rate of 2 mm/s. How fast is the volume increasing (in mm3/s) when the diameter is 40 mm
Answer:
[tex]\dfrac{dV}{dt}=502.65\ mm^3/s[/tex]
Step-by-step explanation:
The volume of a sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3[/tex]
The rate of change of volume means,
[tex]\dfrac{dV}{dt}=\dfrac{d}{dt}(\dfrac{4}{3}\pi r^3)\\\\\dfrac{dV}{dt}=\dfrac{4}{3}\pi \times 3r\times \dfrac{dr}{dt}[/tex]
We have, [tex]\dfrac{dr}{dt}=2\ mm/s\ and\ r=40\ mm[/tex]
So,
[tex]\dfrac{dV}{dt}=\dfrac{4}{3}\pi \times 3\times 20\times 2\\\\=502.65\ mm^3/s[/tex]
So, the volume is increasing at the rate of [tex]502.65\ mm^3/s[/tex].

-4n>24 write a answer as an inequality
Answer:
n < -6
Step-by-step explanation:
-4n>24
Divide each side by -4, remembering to flip the inequality
-4n/-4 < 24/-4
n < -6
Answer:
n < -6
Step-by-step explanation:
We are given the following equation and asked to solve for n:
-4n > 24Divide both sides by -4 to isolate n by itself, and since we are dividing/multiplying a negative number on both sides, we need to flip the inequality sign:

In a certain country, the true probability of a baby being a boy is 0.519. Among the next nine randomly selected births
in the country, what is the probability that at least one of them is a girl?
Answer:
0.9973
Step-by-step explanation:
Given :
Probability of girl, probability of success , 1 - p = 1 - 0.519 = 0.481
1 - p = 0.481
n = 9
Probability that atleast one is girl
Usingbthe binomial probability distribution :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
USing the binomial probability calculator :
p(x ≥ 1) = p(x=1) + p(x=2) + p(x=3) + p(x=4) + p(x=5) + p(x=6) + p(x=7) + p(x=8) + p(x=9)
p(x ≥ 1) = 0.9973 ( from calculator).
16. On a yachting trip in the South Pacific, you discover a previously unknown island. You notice that there is a population of especially fluffy and particularly cute long-eared rabbits living there. These rabbits seem to have no predators at all on the island, and their mating habits seem to be perfectly random. When they are first surveyed, they have an average ear length of about 18 cm. When they are sampled again in five years, what will likely be true of their ear length
Answer: Their ear length will be thesame because there's no force of evolution.
Step-by-step explanation:
Based on the information given in the question as we are informed that the rabbits have no predators and that their mating habits seem to be perfectly random.
We should note that when they are sampled again in five years, due to the fact that there's no source of evolution, their ear length will be thesame. Also, their offspring number will be thesame as well.

Can someone help me with this please
Answer:
Step-by-step explanation:
As we know, the four angles of the rectangle are 90°.
So, we need to find ∠AEB first.
∠AEB=180-44-90 (∠s sum of Δ)
= 46°
We can then work out x.
x=180-59-46 (adj. ∠s on st. line)
x=75°

solve using elimination method. show work -3×+4y=1 -4×+5y=-2
Answer:
Multiply the first equation by 4 and the second equation by -3:
-12x + 16y = 4
12x - 15y = -6
‣ Add the equations:
‣ Solve for y:
y = -2
‣ Substituting y = -2 into the first equation, we get:
-12x + 16 ⋅ (-2) = 4
‣ Solve for x:
x = -3
‣ Solution:
x = -3, y = -2)

The total weight of 9 bags of potatoes is 36 kilograms each bag weights the same amount what is the weight in grams of each bag of potatoes
Answer:
4000
Step-by-step explanation:
36kg = 36000g
36000g/9 bags = 4000g
The weight of one bag of potatoes is 4 Kg,
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
The total weight of 9 bags of potatoes is 36 kilograms.
Then, weight of one bag of Potato is
= 36/9
= 4 Kg
Thus, One bag weigh 4 Kg.
