A rectangular pool has a width of 24 feet. A second rectangular pool has a perimeter of 48 feet, which
is __1
3
the perimeter of the first pool
Answer:
Let x = the length
Let P = the perimeter of the first pool
48 = (1/3)P
144 feet = P
P = 2l + 2w
144 = 2x + 2(24)
144 = 2x + 48
96 = 2x
48 feet = x

Given that p(-3) = 0, p(-1) = 0, and p(5) = 0, which expression could be p(x)?
A) x3–x2–17x –15
B) x3+ x2–17x + 15
C) x3–3x2–13x + 15
D) x3–9x2+ 23x –15
Answer:B
Step-by-step explanation:
The expression which satisfies all three points will be x³–x²–17x –15.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
The given points are p(-3) = 0, p(-1) = 0, and p(5) = 0,
So checking the points in the function:-
P(x) = x³–x²–17x –15.
p(-3) = (-3)³–(3)²–(17x-3) –15 = -27 - 9 + 51 -1 5 = 0
p(-1) = (-1)³– (-1)²–( 17x -1) –15 = -1 -1 + 17 - 15 = 0
p(-5) = (5)³–(5)²–(17x5) –15. = 125 - 25 -85 - 15 = 0
Therefore the expression which satisfies all three points will be x³–x²–17x –15.

how do i solve this and what is the answer?
Answer:
I totally get why you are asking , how do I solve this. there is so much implied about this
Step-by-step explanation:
1st you have to recognize that ∠ACB ( in my drawing ) has that same angle as the arc from A to B , so that's implied. next you have to recognize that the triangle formed by ACB with the 124 degree angle at C is an isosceles and therefore has identical angles at A and B so that's 180 = 124 + 2A , so A = 28° and so does B , then , b/c we know that small angle... you also have to know, that the line AC is perpendicular to AD. that they from a right angle and there for... you now know , that ∠BAD is the other part of that 90 or 90= 28 + ∠BAD so ∠BAD = 62°
I went through that kinda fast, there was several "leaps" of using logic to get to the correct answer , using things you know from prior understanding about angles , circles and geometry, you are putting all of the parts together here. :/ kinda daunting in some ways.
PLEASE HELP!!!!!!!!!!! A clown has two performances today, in cities A and B, which are 240 km apart. The clown drives from City A to City B at a certain speed and performs. On his way back to City A, he drives half the distance at the same speed as before, but then increases his speed by 10 km/h to be on time for his performance in City A. Thus, the drive from B to A takes 2/5 of an hour less than the drive from A to B. At what speed does the clown drive from A to B?
Answer: 50 km/hr
240 = rt
120 = rt1
120 = (r+10)t2
t1 + t2 = t - 2/5 ==> t2 = 1/2 t - 2/5
So you get
240 = rt
120 = (r + 10)(1/2 t - 2/5)
Solve the system
You het 50 km/hr

whats 4 x 2/3 as a multiple of a unit fraction
The expression 4 x 2/3 as a multiple of a unit fraction is 8/3, which is equal to (1/3) x 8.
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.
To express 4 x 2/3 as a multiple of a unit fraction, we need to find a fraction that can be multiplied by a whole number to give us 4 x 2/3.
First, we can simplify 2/3 by dividing both the numerator and denominator by their greatest common factor, which is 1. This gives us:
2/3 = 2 ÷ 1 / 3 ÷ 1 = 2/3
Next, we can multiply 4 by 2/3 to get:
4 x 2/3 = 8/3
To express 8/3 as a multiple of a unit fraction, we can use the fact that any fraction can be expressed as a sum of unit fractions. We can start by expressing 1/3 as a unit fraction:
1/3 = 1 ÷ 3
Next, we can multiply both the numerator and denominator of 1/3 by 3 to get:
1/3 = 3 ÷ 9
Now we can express 8/3 as a sum of unit fractions:
8/3 = (3/9) x 8 = (1/3) x 8 = 8 ÷ 3
Therefore, 4 x 2/3 as a multiple of a unit fraction is 8/3, which is equal to (1/3) x 8.

subtract and write the difference in simplest form 12 5/8 - 7 1/3
Answer:
5 7/24
Step-by-step explanation:
Given the following mathematical expression;
12 5/8 - 7 1/3
First of all, we would subtract the whole numbers;
12 5/8 - 7 1/3 = (12 - 7) 5/8 - 1/3
12 5/8 - 7 1/3 = 5 [5/8 - 1/3]
Next, we subtract the fractions from each other;
5/8 - 1/3
Lowest common multiple (lcm) = 24
5/8 - 1/3 = (15 - 8)/24
5/8 - 1/3 = 7/24
Combining the two parts, we have;
12 5/8 - 7 1/3 = 5 7/24

Nolan invested $5,300 in an account paying an interest rate of 3.8% compounded
annually. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest tenth of a year, for the value of the account to reach $6,880?
HELP
Answer:
7
Step-by-step explanation:
did the question
The amount of money would be $6,880 in the account after 7 years.
What is Compound interest?Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.
A = P(1+r/100)ⁿ
Where:
A = the future value of the investment or loan
P = the principal investment or loan amount
r = the interest rate (decimal)
n = the number of compound periods
Given data as follows:
p = $5,300
r = 3.8%
A = $6,880
A = P(1+r/100)ⁿ
Substitute the values of p,r, and A in the formula,
6,880 = 5,300(1 + 3.8/100)ⁿ
6,880/5,300 = (1 + 0.038)ⁿ
1.2981 = (1.038)ⁿ
n = 6.9954
Rounded to the nearest digit, and we get
n = 7
Therefore, the amount of money would be $6,880 in the account after 7 years.
