Answer:
Train A : 143 tons ; Train B : 18 tons
Step-by-step explanation:
Call train A as A, train B as B
A + B = 161t
A - B = 125t
A = (161+125) : 2 = 143t
B = 143t - 125t = 18t

The formula of Sridharacharya is used. Then the solutions of the equation are 73.19 and -13.19.
What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
The equation is given as
[tex]\rm 4\sqrt{5x + 66} = x +10[/tex]
Squaring both sides, we have
16(5x + 66) = (x + 10)²
16(5x + 66) = x² + 100 + 20x
On simplifying, we get
x² + 100 + 20x -80x - 1056 = 0
x² - 60x - 956 = 0
On solving by formula method, we have
a = 1; b = -60; and c = -965
[tex]\rm x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}\\\\\\x = \dfrac{-(-60) \pm \sqrt{(-60)^2 - 4*1*(-965)}}{2*1}\\\\\\x = 73.19, \ -13.19[/tex]
Thus, the solutions of the equation are 73.19 and -13.19.

in class of 30 children, 60%
can swim. How many children
cannot swim?
Answer: 12 children
Step-by-step explanation:
If 60% can swim, then that means 40% do not swim.
40% = 4/10 = 2/5
2/5 * 30 children = 12 children.
Answer:
12 children cannot swim
Step-by-step explanation:
100% - 60% = 40%
40% cannot swim.
40% can become 0.4.
30 children * 0.4 = 12 children cannot swim

A coin is being flipped 400 times. What is the probability of it landing on heads at most 170 times, rounded to the nearest tenth of a percent?
"at most" is throwing me... what is the formula?
Hello!
We have two probabilities we can use; we have 170/400, for our experiment, and 1/2, which is our theoretical probability.
To solve, we just multiply the two probabilities.
=0.2125≈21.3
Therefore, we have about a 21.3% chance of this event occurring.

Amy volunteers at an animal shelter. She worked 10 hours in March, 12 hours in April, 14 hours in May, and 16 hours in June. If the pattern continues, how many hours will she work in December? Make a table to find the answer.
Answer:
28
Step-by-step explanation:
3th (March): 10
4th: 12
5th: 14
6th: 16
7th: 18
8th: 20
9th: 22
10th: 24
11th: 26
12th ( December): 28
The 4th, 5th, 6th ect are the months because i cant remember the order or how to spell rn
March (1) = 10 hours (first month, second month.. so on)
April (2) = 12 hours (+2)
May (3) = 14 hours (+2)
June (4) = 16 hours (+2)
July (5) = 18 hours (+2)
August (6) = 20 hours (+2)
September (7) = 22 hours (+2)
October (8) = 24 hours (+2)
November (9) = 26 hours (+2)
December (10) = 28 hours (+2)
Amy works 2 extra hours every month.
By December, she would have worked 28 hours.

In how many different ways can a committee with 2 members, be chosen from a group of 4 people?
Answer:
Step-by-step explanation:
We need 2 people out of a group of 4
Let's take a random person, and another to group with the random person we picked. We can group them with 3 different people ( 3 ways )
Now, repeat again, and pick a person to group with the person who is grouped with the first person (except the first person themself) (2 ways)
And repeat again, you will group them with the last person.
So in total, you have 3 + 2 + 1 = 6 ways to pick 2 people from a group of 4.

Step-by-step explanation:
f(0) = 0 , f(2) = -4 , f(4) = -2
0 = f(2x) → f(0) = f(2x) → x = 0 (0,0)
-4 = f(2x) → f(2) = f(2x) → x = 1 (1,-4)
-2 = f(2x) → f(4) = f(2x) → x = 2 (2,-2)
shape of the graph remain without change in vertical axis , but it is compressed in the horizontal direction.

Original price $69.80 with a 15% discount, what is the new price.
Answer:
$59.33
Step-by-step explanation:
To begin, let's start with what we know
Item = 69.80
Discount = 15% or 0.15
So, let's put it into this formula
New Price = Item ( 1 - Discount) Note: P is the final price
= 69.80 ( 1 - 0.15)
= 69.80 ( 0.85 )
= 59.33
The new price is $59.33.
If you have any questions, please let me know in the comments. If you could mark this answer as the brainliest, I would greatly appreciate it!
Answer:
$59.33
Step-by-step explanation:
To find the new price, we need to know what is 15% of 69.80, and then subtract the result from 69.80. To find the percent, we multiply the number by the percent using decimals for the percent. 15% is 0.15, so we multiply 69.80 * 0.15 = 10.47
Next, subtract 10.47 from 69.80.
69.80 - 10.47 = 59.33
The new price is 59.33.
Another method is that since 69.80 is 100 percent, then the new price will be 100% - 15% = 85%. Multiply the 85 percent by 69.80, and find your answer.
0.85 * 69.80 = 59.33
Hope this helps.
