Answer:
9.9
Step-by-step explanation:
The applicable geometric mean rule tells you ...
y = √(9(9+2)) = √99
y ≈ 9.9
__
Additional comment
In this geometry, the right triangles are similar. Ratios of corresponding sides are equal.
hypotenuse/long side = y/9 = (9+2)/y
y^2 = (9)(11)
y = √99 . . . . as above
The long leg is the geometric mean of the (adjacent) long segment and the full hypotenuse.

It takes 5 days to repair 1,250 meters of road. At this rate, how many days will it take to repair 8 kilometers of road?
Answers
Answer :
no. of days used to repair 1250m of road = 5
no. of days used to repair 1m of road = 5/1250
no. of days used to repair 8000m of road (8*1000m ) = 5/1250*8000= 32 days

What is Rectangle?An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°).
A rectangle has equal and parallel opposite sides.
A rectangle has two dimensions—length and width—because it is a two-dimensional form. The rectangle's longer side is its length, while its shorter side is its breadth.
We have a figure of rectangle whose length = 10 + 2x or 18
and width = 10 or 2y+ 4
As, we know the opposite sides of rectangle are equal.
So, 10+ 2x = 18
2x = 8
x= 4
and, 10 = 2y+ 4
2y= 6
y= 3
So, the value of y is 3.

Step-by-step explanation:
2: 1.50+x=π This problem is impossible. This is because Pi is a number that goes for infinitiy so there is no answer for x. This also means ∞ can also be an answer.
Answer:
1. 9
2.
Step-by-step explanation:
1. Mara has $640 in her bank account, she withdraws $30 each month. We don't know how many months will she withdraw until 370$. Let's write an expression first:
640 - 30x = 370
Now, subtract both sides by 640 to get -270:
-30x = -270
Last, divide both side by -30:
-30x = 270
x = 9
Now, we know she withdraws $30 for 9 months.

[tex]\frac{5z+1}{3}[/tex] = 7 ( multiply both sides by 3 to clear the fraction )
5z + 1 = 21 ( subtract 1 from both sides )
5z = 20 ( divide both sides by 5 )
z = 4
(b)
[tex]\frac{5x}{3}[/tex] + 3 = x + 7 ( multiply through by 3 to clear the fraction )
5x + 9 = 3x + 21 ( subtract 3x from both sides )
2x + 9 = 21 ( subtract 9 from both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Find the geometric mean between 28 and 32. Round to the nearest tenth if necessary.
Answers
Answer: The geometric mean is √24 * 32 = √768 = 16√3.
The geometric mean between 28 and 32 is 28.29 after using the formula of the geometric mean.
What is mean?
It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
Let x be the geometric mean between 28 and 32
The formula for the geometric mean:
x = √(a×b)
x = √(28×32)
x = √800
x = 20√2
x = 28.284
or
x = 28.29
Thus, the geometric mean between 28 and 32 is 28.29 after using the formula of the geometric mean.

A local bakery sells cupcakes for $3.50 each. The fixed monthly cost totals $275 which includes rent, utilities, and wages. Each cupcake costs the bakery 0.90 to make.
Answers
Answer: 110 cupcakes
Step-by-step explanation:
Assuming this question is asking for the breakeven point, you can find that by using the formula:
= Fixed cost / Contribution margin
Contribution margin = Sales price - variable cost (amount to make one cupcake)
= 3.50 - 0.90
= $2.60
Breakeven point = 275 / 2.60
= 109.77
= 110 cupcakes

An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 9 more than three times the length of the bottom of the triangle. The last side is 9 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle. What is the expression for the perimeter of the triangle?
Answers
Answer:
The perimeter of the triangle can be expressed as 5x + 18.
Step-by-step explanation:
Perimeter of an object is the sum of the length of its sides.
For the required triangle, we have;
length of the base = x
length of the second side = 3x + 9
length of the third side = x + 9
Perimeter of the triangle = length of the base + length of the second side + length of the third side
= x + (3x + 9) + (x + 9)
= x + 3x + 9 + x + 9
= 5x + 18
The perimeter of the triangle can be expressed as 5x + 18.

a. 5
b. 0.5
C. -5

Answer:
C. -5
Step-by-step explanation:
for g(x) =ax and f(x) = x, both are linear function. There is nothing to be upward or downward and both are lines nothing to compare its narrowness.
If g(x) = ax² vs f(x) = x²
Then a = -5 is the answer (-: downward and 5: vertical stretch)

Sarah and Nathan each picked a bucket of strawberries. Sarah picked 4 1/4 and Nathan picked 3 3/4. How much more did Sarah pick than Nathan?
Answers
Answer: 1/2 buckets
Step-by-step explanation:
Sarah picked 4¹/₄ buckets of grapes and Nathan picked 3³/₄ buckets.
To find out how much Sarah picked more than Nathan, simply subtract Nathan's buckets from Sarah's.
First convert the fractions to improper fractions:
4¹/₄ = 17/4
3³/₄ = 15/4
As the have the same denominator, you can directly subtract them:
= 17/4 - 15/4
= 2/4
= 1/2 buckets
