Answer:
[tex]\frac{4}{9}[/tex]
Step-by-step explanation:
There are two of them, so we will divide the lawn area mowed by 2.
[tex]\frac{8}{9}/\frac{2}{1}= \frac{8}{9}*\frac{1}{2}=\frac{8*1}{9*2} =\frac{8}{18} =\frac{4}{9}[/tex]
-> This also can be simplified with seeing that 8 / 2 = 4, so [tex]\frac{4}{9}[/tex], but I wanted to show the whole mathematical process.
Find the linear equation from this table
Answer:
y=2x+5
Step-by-step explanation:
The slope-intercept form of a linear equation is:
y=mx+b
Where m is the slope and b is the y-intercept.
We can start by finding the slope...
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We can use any two x, y pairs to solve for the slope. In this case let's use (0,5) and (2,9)...
[tex]Slope=\frac{9-5}{2-0}=\frac{4}{2}=2[/tex]
The y-intercept is where the line intersects the y-axis. This means that the x value is 0. In the table we can see when the x value is 0, the y value is 5 meaning the y-intercept is 5...
y=2x+5

What is the constant of proportionality in this proportional relationship? PLS I WILL MAKE U BRAINLELIST
Answer:
The constant of proportionality is [tex]k=\frac{7}{9}[/tex]
Step-by-step explanation:
Recall that the equation for direct variation is [tex]y=kx[/tex] where [tex]y[/tex] varies directly with [tex]x[/tex] and [tex]k[/tex] is the constant of proportionality.
Here, [tex]k=\frac{7}{9}[/tex] since [tex]2(\frac{7}{9})=\frac{14}{9}=1\frac{5}{9}[/tex], [tex]3(\frac{7}{9})=\frac{21}{9}=2\frac{3}{9}[/tex], and so on.

Kamara has a square fence kennel area for her dogs in the backyard. The area of the kennel is 64 ft squared. What are the dimensions of the kennel? How many feet of fencing did she use? Explain.
Answer:
dimensions: 8 ft x 8 ft ║ 32 ft of fence she used.
Step-by-step explanation:
area of the kennel is 64 ft²as its a square, its formula for area: length²
using the formula:
length² = 64
length = √64
length = 8 ft
→ The dimensions of the kennel is 8 ft x 8 ft
Using the length, we can find; how many fencing she used:
formula used: 2 ( length + length )
using the formula:
2 ( 8 + 8 )
2 ( 16 )
32 ft

A bucket of water of mass 15 kg is pulled at constant velocity up to a platform 40 meters above the ground. This takes 16 minutes, during which time 5 kg of water drips out at a steady rate through a hole in the bottom. Find the work needed to raise the bucket to the platform. (Use g=9.8m/s^2.)
Answer:
4900 J
Step-by-step explanation:
The average mass of water raised is ...
(15 kg +(15 -5) kg)/2 = 12.5 kg
The work done to raise it 40 m is ...
W = mgh = (12.5 kg)(9.8 m/s^2)(40 m) = 4900 J

4. Lucy is k years old. She has a sister who is three years younger than she is and
another sister who is five years less than twice Lucy's age. Write an expression, in
simplified form, for the sum of the three girls' ages.
Answer:
4k - 8
Step-by-step explanation:
Lucy is k years old so we know k is an important part of this problem.
Sister 1 is 3 years younger, so she is k - 3 years old.
Sister 2 is 5 years less than twice Lucy's age therefore, she is 2k (twice Lucy's age) - 5 years old.
Now we have: k + (k - 3) + (2k - 5)
We can simplify like terms with the k's and get 4k. then we add (-3) and (-5) to get 4k - 8.
