The required rounding of the number 8.31 ÷ 1.87 is 4.4.
Given that,
To find the simplified value for 8.31÷1.87.
A recurring Decimal is defined as also named repeating decimal, is a decimal number that only consists of repeating digits after a certain interval after the decimal. For example, 94.642642642..., 213.569569... etc.
Here,
8.31÷1.87 = 4.444
Where 4 is a repeating decimal so the round to 1 decimal point is 4.4
Thus, the required rounding of the number 8.31 ÷ 1.87 is 4.4.

A cylinder has a volume of 200 cubic centimeters. If the height of the cylinder is 10 centimeters, what is the radius of the cylinder?
Answer:
The radius of the cylinder is 2.52 cm.
Step-by-step explanation:
The formula for the volume of a cylinder of radius r and height h is
V = πr²h. We can solve this for r² by dividing both sides of the equation by πh:
r² = V / (πh)
Then the desired radius is found by taking the square root of this.
r = √{V / [πh]}
200 cm^2
Here, r² = ------------------- = 6.37 cm^2
3.14(10 cm)
and so r = √6.37 cm^2 = 2.52 cm
The radius of the cylinder is 2.52 cm.
Answer:
radius = 2.52 cm
Step-by-step explanation:
[tex]Volume = \pi r^2 h\\\\200 = \pi r^2 \times 10\\\\\frac{200}{10 \times \pi} = r^2 \\\\6.332 = r^2 \\\\\sqrt{6.332} = r \\\\r = 2.52 \ cm[/tex]
3(h+6) = 2(-5-2h) Solve for h
Answer:
h = -4
Step-by-step explanation:
3(h+6) = 2(-5-2h) Solve for h.
Apply distributive property first on both sides.
3(h+6) = 2(-5-2h)
3h+18 = -10-4h
Next, put the terms with h on one side and the numbers on the other.
3h+18 = -10-4h
7h = -28
Divide both sides by 7 and you have your answer.
7h = -28
h=-4
Answer:
-4
Step-by-step explanation:
First, expand the brackets by multiplying the left bracket all by 3 and the right all by 2. This gives 3h+18=-10-4h.
You want h all on one side, so add 4h to both sides, leaving 7h+18=-10.
Subtract 18 on both sides to leave only h and the coefficient on the left. This gives 7h=-28.
Dividing both sides by 7 isolates the x and gives h=-4.

Identify the mistake.
The mistake is that it is 1/16 not 16. The person probably did the reciprocal or incorrectly used the fraction
Answer:
The exponent for the answer should be -2. Therefore, the answer will be 4⁻² or 1/16.
Step-by-step explanation:
When dividing fractions, you subtract the exponents as long as they have the same base.
Since the exponents both have the base of 4, subtract 9 - 11.
9 - 11 = -2
The exponent would be -2 and the answer would be 4⁻².
When an exponent is negative, you take the inverse of the base raised to the positive exponent.
Since 4² = 16 or 16/1, 4⁻² would be 1/16.
The answer would be 4⁻² or 1/16.

Therefore, that's the probability
Solve for f: efg - h = i
Given:
The equation is:
[tex]efg-h=i[/tex]
To find:
The value of f.
Solution:
We have,
[tex]efg-h=i[/tex]
We need to isolate f to find the value of f.
Adding h on both sides, we get
[tex]efg-h+h=i+h[/tex]
[tex]efg=i+h[/tex]
Dividing both sides by [tex]eg[/tex], we get
[tex]\dfrac{efg}{eg}=\dfrac{i+h}{eg}[/tex]
[tex]f=\dfrac{i+h}{eg}[/tex]
Therefore, the value of f is [tex]f=\dfrac{i+h}{eg}[/tex].

Answer:
(a) -12
(b) 37
(c) -840
Step-by-step explanation:
We simply have to plug in the values for each expression.
2 + -3(3) - 5 = 2 + -9 - 5 = -7 - 5 = -12
5(2) - 4(-3) + 3(5) = 10 - -12 + 15 = 10 + 12 + 15 = 22 + 15 = 37
7(2^3)(-3)(5) = 7(8)(-15) = 56(-15) = -840

Chang wants to rent a boat and spend at most $44. the boat cost $8 per hour, and chang has a discount coupon for $4 off. what are the possible numbers of hours chain could rent the boat? Use "t" for number of hours .
Answer:
6 hours.
Step-by-step explanation:
Here's my work.
Chang only wanted to spend $44, and the boat costs $8/hr. So, the variable would only be 8t, and you would put 44 on the other side.
Then, you'd put -4 on the side with 8t, because you can take off $4.
So, the setup would be;
44 = 8t - 4.
The sum of three numbers is 10. Two times the second number minus the first number is equal to 12. The first number minus the second number plus twice the third number equals 7. Find the numbers.
9514 1404 393
Answer:
(-2, 5, 7)
Step-by-step explanation:
The problem statement lets us write three equations for the three numbers x, y, and z.
x + y + z = 10
-x + 2y = 12
x - y + 2z = 7
__
Adding the second equation to each of the other two gives ...
3y +z = 22
y +2z = 19
Subtracting the second of these from double the first gives ...
2(3y +z) -(y +2z) = 2(22) -(17)
6y +2z -y -2z = 44 -19
5y = 25
y = 5
z = 22 -3(5) = 7 . . . . . . from 3y+z=22
x = 10 -5 -7 = -2 . . . . . .from x+y+z=10
The numbers are (x, y, z) = (-2, 5, 7).
What is the solution to this system?
x - y = 6
y = 2x - 5

Kayden is a stunt driver. One time, during a gig where she escaped from a building about to explode, she drove at a constant speed to get to the safe zone that was 160 meters away. After 3 seconds of driving, she was 85 meters away from the safe zone. Let D(t) denote the distance to the safe zone D (measured in meters) as a function of time t (measured in seconds).
Which of the below formulas is the correct function's formula?
A. D(t) = -25t + 160
B. D(t) = 25t + 160
C. D(t) = -25t - 160
D. D(t) = 25t - 160
Step-by-step explanation:
A. D(t) = -25t + 160
this is the correct answer because if you substitute 3 you get 85

a right triangle has legs of lengths 6 and 2, what is the length of the hypotenuse to the nearest tenth
Answer:
6.3
Step-by-step explanation:
[tex]6^{2} + 2^{2} = x^{2}[/tex]
40 = [tex]x^{2}[/tex]
[tex]\sqrt{40} = \sqrt{x^{2} }[/tex]
x = 6.3
Answer:
6.3
Step-by-step explanation:
Pythagoras' Theorem (or Pythagorean Theorem) states a²+b²=c², where c is the hypotenuse.
We can use this equation and swap a and b for 6 and 2. This gives 6²+2²=c², which can be expanded to 36+4=c², and further c²=40.
To work out c, we need to square root both sides, leaving c=6.3245553203367586639977870888654, which rounded to 1 decimal place (nearest tenth) is 6.3.
