The longest straw that can fit inside a 5-inch cylindrical cupm if the straw is placed at the angle in the cup, is 6- inches.
what is the approximate length of the cylinder's radius?
Since the straw is 6 inches long, the approximate length of the cylinder's radius is 3.32 in
To find the radius of the cylinder, we need to apply Pythagoras' theorem.
What is Pythagoras' theorem?Pythagoras' theorem states that in any right-angled triangle, the square of the hypotenuse side equals the sum of the squares of the other two sides.
Mathematically, c² = a² + b² where
c = hypotenusea and b = other sides.Now, since the 6 inch straw inclined at an angle forms a right angle with the radius,r and length of the cylinder, h.
Since the length of the straw is the hypotenuse side, L we have that
L² = h² + r²
Radius of the cylinderMaking r the radius of the cylinder subject of the formula, we have
r = √(L² - h²)
Given that
L = 6 in and h = 5 inSubstituting the values of the variables into the equation,we have
r = √(L² - h²)
r = √(6² - 5²)
r = √(36 - 25)
r = √11
r = 3.316 in
r ≅ 3.32 in
So, the approximate length of the cylinder's radius is 3.32 in

Instead of using the values {1, 2, 3, 4, 5, 6} on dice, suppose a pair of dice have the following {1, 2, 2, 3, 3, 4} on one die and {1, 3, 4, 5, 6, 8} on the other. Find the probability of rolling the sum of 7 with these dice. Be sure to reduce.
The dice will show a sum of 7 if you roll
• 1 and 6
• 2 and 5 (2 ways)
• 3 and 4 (3 ways)
so there are 6 ways of rolling a sum of 7. Out of 6 × 6 = 36 possible outcomes, the probability of rolling a sum of 7 is 6/36 = 1/6.

C) $8,287.61 D) $7,650.44
Answer:
$7650.44
Step-by-step explanation:
Annual interest rate = 4.02%
but compound 4 times per year, means quarterly compound
quarterly interest rate = 4.02%/4 = 1.005%
Account balance = 4734 * (1.01005)^48 [compound 4 times a year for 12 years]

What angles are coterminal to an angle measuring 2π3 or −11π7?
By definition of coterminal angles, the angle 2π/3 has two coterminal angles: θ' = 14π/3 and θ' = - 4π/3. The angle - 11π/7 has no coterminal angles.
How to find coterminal angles
Two angles are coterminal when their terminal ends have the same direction. By the fact that two consecutive coterminal angles have a difference of 2π, we find the following definition:
θ' = θ ± 2π · i, i ∈ [tex]\mathbb{N}_{O}[/tex] (1)
Now we proceed to determine the coterminal angles for each case:
a) θ = 2π/3
θ' = 14π/3, θ' = - 4π/3
b) θ = - 11π/7
There are no coterminal angles.
By definition of coterminal angles, the angle 2π/3 has two coterminal angles: θ' = 14π/3 and θ' = - 4π/3. The angle - 11π/7 has no coterminal angles.

Hi Student!
Usually the first step that I take for any problem would be to gather any important information that would be needed in the problem. However, for this problem, it is pretty straight forward because we just need to solve for the unknown which is x.
Add 3 to both sides
[tex]8x - 3 = 7[/tex][tex]8x - 3 + 3 = 7 + 3[/tex][tex]8x = 10[/tex]Divide 8 from both sides
[tex]\frac{8x}{8} = \frac{10}{8}[/tex][tex]x = \frac{10}{8}[/tex][tex]x = 1.25[/tex]For the first equation, we were able to solve for x and get that the solution for the unknown is 1.25
Subtract 5 from both sides
[tex]5+7x=24[/tex][tex]5 - 5+7x=24- 5[/tex][tex]7x=19[/tex]Divide both sides by 7
[tex]\frac{7x}{7}=\frac{19}{7}[/tex][tex]x=\frac{19}{7}[/tex]For the second equation, we are able to solve for x and get that the solution for the unknown is 19/7
Subtract 6 from both sides
[tex]5=6+4x[/tex][tex]5-6=6-6+4x[/tex][tex]-1=4x[/tex]Divide both sides by 4
[tex]\frac{-1}{4}=\frac{4x}{4}[/tex][tex]\frac{-1}{4}=x[/tex][tex]-0.25=x[/tex]For the final equation, we are able to solve for x and get that the solution for the unknown is -0.25
Answer:
1) [tex]x=\frac{5}{4}=1\frac{1}{4}[/tex]
2) [tex]x=\frac{19}{7}=2\frac{5}{7}[/tex]
3) [tex]x=-\frac{1}{4}[/tex]
Step-by-step explanation:
1) 8x - 3 = 7
1. Group all constants on the right side of the equation
[tex]8x-3=7[/tex]
Add 3 to both sides:
[tex]8x-3+3=7+3[/tex]
Simplify the arithmetic:
[tex]8x=7+3[/tex]
Simplify the arithmetic:
[tex]8x=10[/tex]
2. Isolate the x
[tex]8x=10[/tex]
Divide both sides by 8:
[tex]\frac{8x}{8}=\frac{10}{8}[/tex]
Simplify the fraction:
[tex]x=\frac{10}{8}[/tex]
Find the greatest common factor of the numerator and denominator:
[tex]x=\frac{5\cdot 2}{4\cdot 2}[/tex]
Factor out and cancel the greatest common factor:
[tex]x=\frac{5}{4}[/tex]
2) 5 + 7x = 24
1. Group all constants on the right side of the equation.
[tex]5+7x=24[/tex]
Subtract 5 from both sides:
[tex]5+7x-5=24-5[/tex]
Group like terms:
[tex]7x+5-5=24-5[/tex]
Simplify the arithmetic:
[tex]7x=24-5[/tex]
Simplify the arithmetic:
[tex]7x=19[/tex]
2. Isolate the x
[tex]7x=19[/tex]
Divide both sides by 7:
[tex]\frac{7x}{7}=\frac{19}{7}[/tex]
Simplify the fraction:
[tex]x=\frac{19}{7}[/tex]
3) 5 = 6 + 4x
1. Swap sides
[tex]5=6+4x[/tex]
Swap sides:
[tex]6+4x=5[/tex]
2. Group all constants on the right side of the equation
[tex]6+4x=5[/tex]
Subtract 6 from both sides:
[tex]6+4x-6=5-6[/tex]
Group like terms:
[tex]4x+6-6=5-6[/tex]
Simplify the arithmetic:
[tex]4x=5-6[/tex]
Simplify the arithmetic:
[tex]4x=-1[/tex]
3. Isolate the x
[tex]4x=-1[/tex]
Divide both sides by 4:
[tex]\frac{4x}{4}=\frac{-1}{4}[/tex]
Simplify the fraction:
[tex]x=\frac{-1}{4}[/tex]

Linear equations with one unknownThe most common use of linear equations is to solve problems involving an unknown variable, generally (but not always) x, and a known constant.
Solving linear equations requires isolating the unknown variable on one side of the equation and simplifying the remainder. Anything done to one side of the equation must also be done to the other when simplifying.
An equation of:
[tex]ax+b=0[/tex]
A typical linear equation with one unknown is in which a and b are constants and x is the unknown variable. In this case, we would isolate x by removing b from both sides of the equation before solving for it. We'd then multiply both sides of the equation by a, yielding the following result:
[tex]x = -\frac{b}{a}[/tex]

Answers: 585, 587, and 593
Basically everything except 599
==============================================================
Why?
Those answers in bold are closer to 590 than they are to 580 or 600. When rounding to the nearest ten (not tenth) we look at the units digit. If it is 5 or larger, then we bump the tens digit up by 1 and replace the units digit with a 0.
This explains why 585 and 587 round to 590
The number 599 rounds to 600 for similar reasoning, but we cross it off the list since we want 590.
The number 593 rounds to 590 because the 3 in the units digit isn't 5 or larger. So we just replace the 3 with 0 and keep everything else as is.
