An algebraic expression is a mathematical phrase that contains numbers, variables (like x or y) and operators (like add,subtract,multiply, and divide).
We have to form the algebraic expression for the phrase
" The product of 86 and the depth of the river"
Let the depth of the river be 'd'
Therefore, the algebraic expression = Product of '86' and 'd'
= [tex] 86 \times d [/tex]
= 86d.
Therefore, the algebraic expression for the given phrase is "86d".

4.Krissa drew a circle with a radius of 4 inches.
Fill in the blanks.
The area of the circle is _______ square inches and the circumference is _______ inches.
64π, 16π
16π, 8π
16π, 64π
8π, 16π
To calculate the area of a circle, use the formula A = πr², where r is the radius. For this specific circle with a radius of 4 inches, the area is 16π square inches, and the circumference formula is C = 2πr, resulting in a circumference of 8π inches.
To find the area of a circle: A = πr². Substituting the given radius of 4 inches, we get Area = π(4)² = 16π square inches. The circumference of a circle is C = 2πr. Substituting the radius, we get C = 2π(4) = 8π inches.

If the height of Mount Everest is about 8.8×103 meters, and the height of the Empire State Building is about 3.8×102 meters, which of these statements is true?
Answer:
option C is correct, i.e. Mount Everest is about 23 times as tall as the Empire State Building .
Step-by-step explanation:
Given options are:-
A. There is no way to compare these heights .
B. Mount Everest is about 40 times as tall as the Empire State Building .
C. Mount Everest is about 23 times as tall as the Empire State Building .
D. The Empire State Building is about 23 times as tall as Mount Everest.
Given the height of Mount Everest is about 8.8×10^3 meters, and the height of the Empire State Building is about 3.8×10^2 meters.
Finding ratios of given heights:-
[tex]\frac{Mount\;\;Everest}{Empire\;\;State\;\;Building} =\frac{8.8*10^3m}{3.8*10^2m} \\\\\frac{Mount\;\;Everest}{Empire\;\;State\;\;Building} =23.15789474 \approx 23 \\\\Mount\;\;Everest=23*(Empire\;\;State\;\;Building)[/tex]
Hence, option C is correct, i.e. Mount Everest is about 23 times as tall as the Empire State Building .

Which choice is the conjugate of the expression below when x -5?
4 - x+5
A. 4 + x - 5
B. 4 - x - 5
C. 4 - x + 5
D. 4 + x + 5
The option which is the conjugate of the expression 4 - (x + 5) will be D. 4 + (x + 5).
What is a conjugate?It should be noted that conjugate simply means changing the sign that is between two terms in a binomial.
In this case, the given expression is 4 - (x + 5). Therefore, one simply has to change the subtraction sign. This means one has to has to change the subtraction sign to addition. This will be 4 + (x + 5).
In conclusion, the correct option is 4 + (x + 5).

The conjugate of the expression 4 - (x + 5) is formed by changing the minus sign to a plus sign, resulting in the expression 4 + x + 5, which corresponds to option D.
Explanation:The conjugate of a binomial expression like 4 - (x + 5) is obtained by changing the sign between the two terms. Hence, the conjugate of this expression would change the subtracted term (-x - 5) to its additive inverse, which is (+x + 5). Therefore, the correct choice is 4 + x + 5, which is option D.

What is the equation of the midline for the function y = 2sin(x - π) + 3
The equation of the midline for the function 2sin (x - π) + 3 is y = 3.
What is the Midline of a Function?The midline of a function is the line horizontal to the minimum value and maximum value of the function.
Given function is 2sin (x - π) + 3.
We know the trigonometric formula,
sin (A - B) = sin A cos B - cos A sin B
sin (x - π) = sin x cos π - cos x sin π
= (sin x × -1) - (cos x × 0) [Since cos π = -1 and sin π = 0]
= -sin x
So, 2sin (x - π) + 3 = -2sinx + 3
Now, we know that,
-1 ≤ sin x ≤ 1
Multiplying whole sides by -2,
2 ≥ -2sin x ≥ -2
[since the inequality sign changes when negative is multiplied or divided]
Adding 3 throughout,
5 ≥ -2sin x + 3 ≥ 1
Maximum value is 5 and minimum value is 1.
Midline value = (5 + 1) / 2 = 3
So the equation of the midline is y = 3.
Hence the equation of midline is y = 3.

First question:
Your total restaurant bill is the items you have purchased plus the sales tax and plus the tip (if there’s any). Sales tax is added to your purchase because this is tax imposed to the consumer and not to the buyer. The buyer is only required to collect this tax from the buyer.
Second question:
A check is a financial instrument wherein the bank is required to pay when presented or encashed to them. You just have to make sure that you have account balance to that certain bank.
Third question:
The way of payment not any more common in the most modern economies is the bartering. Both credit cards and cash are the most common way of paying for your purchases.
Answer:
1. the items purchased plus sales tax and tip.
2. a promissory note (I.O.U.)
3. bartering

Suppose that 24% of people own dogs. if you pick two people at random, what is the probability that they both own a dog?
To find the probability that both people randomly picked own a dog, we multiply the probability of one person owning a dog (24%) by itself, resulting in a 5.76% chance that both own a dog.
The question is asking us to calculate the probability that two randomly selected people both own a dog, given that 24% of people own dogs. Since the events (each person owning a dog) are independent, the probability of both events happening is the product of their individual probabilities.
Let's denote the probability of one person owning a dog as P(dog) = 0.24. Then, for two independent people, the probability that both own a dog is [tex]P(dog) \times\ P(dog) = 0.24 \times\ 0.24 = 0.0576.[/tex]
So, the probability that both people picked at random own a dog is 5.76%.
