Answer:
x < -1
Step-by-step explanation:
Let the unknown number be x
nine more than sum of eight times a number and seventeen, is expressed as;
9 > 8x + 17
Subtract 17 from both sides
9 - 17 > 8x+17-17
-8 > 8x
8x < -8
Divide both sides by 8
8x/8 < -8/8
x < -1
Hence the quotient is x < -1
A tetrahedron is a triangular pyramid whose four faces are identical equilateral triangles. The total lateral surface area is 93 square centimeters. Find the surface area of the tetrahedron.
Answer:
Step-by-step explanation:
The total area is four times a face area and the lateral area is three times a face area.
Let x be the total surface area then
x/93=4/3
x=4(93)/3

time, but Amy drives at 50 miles per hour and Ed drives at 40 miles per hour.
How much sooner will Amy arrive to the destination than Ed?
Answer:
Since there are two cars, each car, then, drove 104/2 = 52 miles. But one car is traveling 8 miles per hour faster.

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.

A researcher in sports equipment is investigating the design of racing swimsuits for women. The researcher selected a samp The difference in the sample mean swim times will be calculated. Which of the following is the appropriate inference procedure for analyzing the results?
a) A two-sample t-interval for a difference between sample means
b) A two-sample t-interval for a difference between population means
c) A one-sample t-interval for a sample mean
d) A one-sample t-interval for a population mean
e) A matched pairs t-interval for a mean difference
Answer: B. A two sample t-interval for a difference between population means.
Step-by-step explanation:
The appropriate inference procedure for analyzing the results is the two sample t-interval for a difference between population means.
The two-sample T-interval is simply used in the estimation of the difference that occurs in two population means. Since two independent groups mean are being considered, the appropriate test will then be two sample t-interval for a difference between population means

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.

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

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.

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.

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
