i hope this helps :)
Let us first resolve the given numbers into prime factors.
By prime factorization,
[tex] \longmapsto [/tex] √8 = √( 2 × 2 × 2)
[tex] \longmapsto [/tex] √8 = 2√2
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
[tex] \longmapsto [/tex] √98 = √( 2 × 7 × 7)
[tex] \longmapsto [/tex] √98 = 7√2
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
[tex] \longmapsto [/tex] √32 = √( 2 × 2 × 2 × 2 × 2)
[tex] \longmapsto [/tex] √32 = 2 × 2√2
[tex] \longmapsto [/tex] √32 = 4√2
According to the question,
[tex] \longmapsto [/tex] √8+√98+√32
[tex] \longmapsto [/tex] 2√2 + 7√2 + 4√2
Taking √2 as common.[tex] \longmapsto [/tex] √2(2 + 7 + 4)
[tex] \longmapsto [/tex] √2(13)
[tex] \longmapsto [/tex] 13√2
So, we get that :

Answer:
14 days
Step-by-step explanation:
you divide the total distance, 35, by the amount of miles ran per day, 2.5, to get 35/2.5=14.
A kite has A = 120 cm2 and d1 = 16 cm. Identify the length of d2.
Answer:
d₂ = 15 cm
Step-by-step explanation:
The area (A) of a kite is calculated as
A = [tex]\frac{1}{2}[/tex] d₁d₂
Here A = 120, d₁ = 16 , then
[tex]\frac{1}{2}[/tex] × 16 × d₂ = 120
8d₂ = 120 ( divide both sides by 8 )
d₂ = 15 cm

Kelli Rae invested $220,000 in a savings account with simple interest. After 10 years, Kelli Rae had $250,000. What is the interest rate on this account?
Answer:
Interest rate = 1.363% (Approx.)
Step-by-step explanation:
Given:
Amount invested P = $220,000
Amount after 10 year = $250,000
Number of year = 10 year
Find:
Interest rate
Computation:
A = P + I
Amount of interest = $250,000 - $220,000
⇒ Amount of interest = $30,000
Amount of interest = PRT
⇒ 30,000 = (220,000)(R)(10)
⇒ 30,000 = (2,200,000)(R)
⇒ R = 0.013636
Interest rate = 1.363% (Approx.)

hello there!
as you said, there is only able one output ( y ) for each input ( x ) for it able to become a function
here is a little example of a "table" to help me explain this a little better for you!
input ( x ) | output ( y)

Write 174% as a fraction in simplest form.
Answer:
The answer should be [tex]\frac{87}{50}[/tex]
Step-by-step explanation:
1.74 = [tex]\frac{174}{100}[/tex] = [tex]\frac{87}{50}[/tex]
Answer:
174% = 87/50 = 1 37/50 as a fraction
Step-by-step explanation:
174% = 174/100
Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(174,100) = 2. So,
(174÷2)/(100÷2) = 87/50 when reduced to the simplest form.
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 174/100 is also equal to 1 37/50 when expressed as a mixed number.

What is the equation of the line that is parallel to the line 6x+3y=4 and has a y-intercept of −6?
Answer:
y=-2x-6
Step-by-step explanation:
Slope intercept form of a line: y=mx+b (m is the slope and b is the y-intercept)
Convert our given line 6x+3y=4 into slope-intercept form to find the slope
Subtract 6x on both sides
3y=-6x+4
Divide 3 on both sides
y=-2x+4/3
The slope of the given line is the coefficient of x, -2
Parallel lines have the same slope, so the equation we're solving for also has a slope of -2
We also know that the y-intercept is -6, so we now have all the info we need to make the equation:
y=-2x-6
a1 + a2 + a3 + a4 + a5

The perimeter of a rectangular chicken coop is 30 feet. the width is w feets and the length is w + 4 feet. what is the length and width of the coop
The width and length of the chicken coop are 5.5 feet and 9.5 feet respectively.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a rectangle is given by P = 2L + 2W, where L is the length, W is the width and P is the perimeter.
We know that the width is w feet and the length is w+4 feet.
Given that the perimeter of the chicken coop is 30 feet, we can set up the following equation:
30 = 2(w + 4) + 2w
We can simplify this equation by combining like terms:
30 = 2w + 8 + 2w
30 = 4w + 8
22 = 4w
w = 5.5
So the width of the coop is 5.5 feet.
To find the length of the coop, we can use the information that the width is 5.5 feet and the length is w+4 feet.
The length of the coop is 5.5 + 4 = 9.5 feet

Given that x^6 = 64, which of the following could be the value of 9x^2 + 3x ?
Answer:
42,-42
Step-by-step explanation:
We first solve for x from x^6 = 64, by taking the root of both sides, and we get x = 2,-2
We then plug in both of the x values and get 42,-42
PS: That should be the right answer but you didn't include the possible answers, and I somehow also got 30 when plugging in -2, but just try it yourself to be safe.

Ann has $ 1, $10, and $20 bills. She has 4 times as many $20 bills as $10 bills. She has 3 times as many $1 bills as $20 bills. She has a total of $204 . Drag and drop the number of $1, $10, and $ 20 bills she has.
Answer:
Ann has 24 $1 bills, 2 $10 bills, and 8 $20 bills.
Step-by-step explanation:
Given that Ann has $1, $10, and $20 bills, and she has 4 times as many $20 bills as $10 bills and 3 times as many $1 bills as $20 bills, taking a total of $204, to determine the number of $1, $10, and $20 bills she has, she needs to perform the following calculation:
1 = 3x20 = 3x4x10 = 12x10
20 = 4x10
10 = 10
(12 x 1) + (4 x 20) + 10 = 12 + 80 + 10 = 102
(24 x 1) + (8 x 20) + (2 x 10) = 24 + 160 + 20 = 204
So Ann has 24 $1 bills, 2 $10 bills, and 8 $20 bills.
