i need an explanation please...
Answer:
window sill height =9.75 meters
Step-by-step explanation:

On a Saturday, Saul can cut 4 lawns in 6 hours. If Mitch can mow lawns at the same rate, how long will it take him to mow 9 lawns?
12 hours
12 3/4 hours
6 hours
13 1/2 hours
Answer:
13 1/2 is your answer.
Step-by-step explanation:
With the same ratio the time taken Mitch to mow 9 lawns will be 13 + 1/2 thus option (D) is correct.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
Saul can cut 4 lawns in 6 hours.
The ratio of hours to lawns will be as,
6/4
Suppose the time taken to mow 9 lawns to Mitch is x hours.
The ratio of hours to lawns will be as
x/9
Since the rate is the same thus ratio must be the same.
x/9 = 6/4
x = 6/4 x 9
x = 13.5 = 13 + 1/2
Hence"With the same ratio, the time taken Mitch to mow 9 lawns will be 13 + 1/2".

Cheyenne bought 60 tickets for rides at an amusement park. Each ride costs 4 tickets, and Cheyenne has been on x rides so far. Write an expression is equivalent to the number of tickets that Cheyenne has left?
Answer:
x=number of rides taken
y=number of tickets left
60=4(x)+y
For x=4 simplify 2x+(6-3)2

3. State if each of the labeled points is a local min, max or
neither.
Is the function even or odd? Explain.
Please explain right I’m giving 100 points in this that means the 2 people Who answers this will get 50 each
Answer:
(5, 7) is a local maximumFunction is oddStep-by-step explanation:
As we see on the graph:
point (1,2) on the falling section,point (3,3) on the rising section,point (5,7) on the top section,... of the local intervals. therefore only point (5, 7) is a local maximum.
Absolute minimum is - oo, absolute maximum is + oo
A function is even if its graph is symmetric with respect to the y-axis. A function is odd if its graph is symmetric with respect to the origin.The given function is odd as per above definition

Step-by-step explanation:
Given: f(1) = 3x– 7, 9(x) = 2x^2 – 3x +1, h(x) = 4x + 1, k(x) = –x^2+3
Find: (h o g) (x)
Answer:
(h o g) (x) = h(g(x))
Step-by-step explanation:
(h o g) (x) = h(g(x)) = 4(g(x))+1 = 4(2x^2 -3x + 1 ) + 1
= 4*2x^2 - 4*3x + 4*1 + 1
= 8x^2 - 12x + 4 + 1
= 8x^2 - 12x + 5

The answer is below
Step-by-step explanation:
The question is not complete. But I would solve a similar question.
Solution:
A quadrilateral is a polygon shape with four sides and four angles.
Two polygons are said to be similar if they have the same shape and the ratio of their corresponding sides are equal to each other (that is their corresponding sides are in the same proportion).
Given that Quadrilateral ABCD is similar to quadrilateral GHIJ, hence their corresponding sides are similar.
[tex]\frac{AB}{GH} = \frac{AD}{GJ} \\\\\frac{x}{24} = \frac{4}{12} \\\\x=\frac{4*24}{12}\\\\x=8[/tex]

A rental car company charges $31 per day to rent a car and $0.13 for every mile
driven. Jocelyn wants to rent a car, knowing that:
She plans to drive 500 miles.
• She has at most $220 to spend.
.
Write and solve an inequality which can be used to determine d, the number of days
Jocelyn can afford to rent while staying within her budget.
Answer:
The number of days is at most 5 days
= d ≤ 5 days
Step-by-step explanation:
A rental car company charges $31 per day to rent a car and $0.13 for every mile driven. Jocelyn wants to rent a car, knowing that:
She plans to drive 500 miles.
• She has at most $220 to spend.
At most means Less than or equal to $220
The inequality for expressing this = ≤
Hence, the inequality which can be used to determine d, the number of days Jocelyn can afford to rent while staying within her budget.
$31 × d + $0.13 × 500 miles ≤ $200
The inequality is given as:
31d + 65 ≤ 220
Solving further
31d ≤ 220 -65
31d ≤ 155
d ≤ 155/31
d ≤ 5
Therefore, the number of days is at most 5 days
if x:y=3:5 find the ratio 3×+4y:8x +5y
Answer:
29: 49
Step-by-step explanation:
Since x:y= 3:5,
[tex] \frac{x}{y} = \frac{3}{5}[/tex]
Cross multiply:
[tex]5x = 3y[/tex]
Divide by 5 on both sides:
[tex]x = \frac{3}{5} y[/tex]
[tex] \frac{3x + 4y}{8x + 5y} \\ = \frac{3( \frac{3}{5}y) + 4y }{8( \frac{3}{5}y) + 5y } \\ = \frac{ \frac{9}{5}y + 4y }{ \frac{24}{5}y + 5y } \\ = \frac{9y + 5(4y)}{24y + 5(5y)} \\ = \frac{9y + 20y}{24y + 25y} \\ = \frac{29y}{49y} \\ = \frac{29}{49} [/tex]
Thus, 3x+4y: 8x+5y= 29: 49.

Answer:
((4 x 16) ÷ 2) - 8
Step-by-step explanation:
There are many ways to solve this equation, but an easy one would be ((4 x 16) ÷ 2) - 8
4 times 16 = 64
64 ÷ 2 = 32
32 - 8 = 24
Hope this helps :)
