Step-by-step explanation:
Ive friends each knit one part of a scarf that is 1 5/ 12 yards long.
Hencfy, the fractions of the scarf each friend could have knit is calculated by comparing the options
A. 1 /12 + 2 /12 + 3 /12 + 8 /12 + 4 /12
Lowest Common Denominator = 12
Hence = 18/12 = 1 6/12 = 1 1/2
Option A is wrong
B. 1 /12 + 6/ 12 + 3 /12 + 2 /12 + 4 /12
Lowest Common Denominator = 12
Hence = 16/12 = 1 4/12 = 1 1/3
Option B is wrong
C. 2/12 + 3/ 12 + 3/ 12 + 2/ 12 + 5/ 12
Lowest Common Denominator = 12
Hence = 15/12 = 1 3/12 = 1 1/4
Option C is wrong
D. 5 /12 + 1 /12 + 4/ 12 + 2 /12 + 5 /12
Lowest Common Denominator = 12
Hence = 17/12 = 1 5/12
Option D is correct
Therefore, the fractions of the scarf each friend could have knit is Option D

where is the sand dollar
Answer:
maybe the palm tree is at 5 the rock at -2 and the sand dollar at 0?
or, somthing like that
Step-by-step explanation:
The sand dollar is at zero which is 2 units away from rock and five units away from palm tree
What is Number system?A number system is defined as a system of writing to express numbers.
A sand dollar is 2 units away from rock and five units away from palm tree, We have to find the location of the sand dollar
Let the rock is at -2 on number line
The palm tree is at 5 on number line
So the sand dollar is at 0, as zero is two units away from rock and tree is five units away
Hence, the sand dollar is at zero which is 2 units away from rock and five units away from palm tree

Which function is graphed below?
On a coordinate plane, an exponential decay function is shown. The curve starts in quadrant 2 and decreases into quadrant 1. It crosses the y-axis at (0, 3) and approaches y = 0 in quadrant 1.
1)y = one-third (3) Superscript x
2)y = 3 (one-third) Superscript x
3)y = (one-half) Superscript x Baseline + 2
4)y = (2) Superscript x Baseline minus 1
By solving a system of equations, we will see that the rational function is:
[tex]f(x) = \frac{12}{(x + 2)} -3[/tex]
Which rational function is graphed below?
First, we need to see the x-value of the vertical asymptote, here we can see that the vertical asymptote happens at x = -2, then the denominator will be something like:
d = (x - (-2)) = (x + 2).
Then our rational function will be something like:
[tex]f(x) = \frac{a}{(x + 2)} + c[/tex]
In the graph we can see two things, first:
f(0) = 3
f(1) = 1
Replacing that in our function, we get:
[tex]\frac{a}{(0 + 2)} + c = 3\\\\ \frac{a}{(1 + 2)} + c = 1[/tex]
This is a system of equations, that can be rewritten as:
a/2 + c = 3
a/3 + c = 1
Isolathing c in both equations, we get:
a/2 - 3 = -c = a/3 - 1
Then we have:
a/2 - 3 = a/3 - 1
Now we can solve this for a:
a/2 - a/3 = 3 - 1
a/6 = 2
a = 2*6 = 12
And the value of c is given by:
-c = a/3 - 1 = 12/3 - 1 = 4 - 1 = 3
c = -3
Then the rational function is:
[tex]f(x) = \frac{12}{(x + 2)} - 3[/tex]

Answer:
c. 60
Step-by-step explanation:
If we know that d is 90 degrees. We can make a conclusion that we have a 30, 60, 90 triangle. D is 90 and a triangle is 180 degrees. So we can automatically knock off 90 from the 180 giving us another 90. Now we know that we have a 30 and 60 to work with. F is an angle that is larger than E. So E is 30 and F is 60.
Liam spent $4.76 on a salad bowl, and $3.81 on a cup of coffee. He paid using TWO ten dollar bills. What was Liam's change?
Answer:
11.43
Step-by-step explanation:
You can start this by adding the total cost of the salad and the coffee.
4.76 + 3.81 = 8.57
Then you have the paid amount of 20 bucks because there was two tens.
20 - 8.57 = 11.43.
A shop keeper buys a pair of shoes for birr 180 and sells it for birr 225 what is the percentage profit
Answer:
Percentage profit = 20%
Step-by-step explanation:
Given the following data;
Cost price = birr 180
Selling price = birr 225
To find the percentage profit;
First of all, we would determine the profit;
Profit = selling price - cost price
Profit = 225 - 180
Profit = birr 45
Next, we would determine the percentage profit;
[tex] Percentage \; profit = \frac{profit}{selling \; price} * 100[/tex]
[tex] Percentage \; profit = \frac{45}{225} * 100[/tex]
[tex] Percentage \; profit = 0.2 * 100[/tex]
Percentage profit = 20%

a dilation with a scale factor less than 1 and then a
translation
a dilation with a scale factor greater than 1 and then
a reflection
a dilation with a scale factor greater than 1 and then
a translation
Answer:
a dilation with a scale factor greater than 1 and then a translation (the last option)
The composition of transformation is a dilation with a scale factor greater than 1 and then a translation.
What is Translation?A translation only moves a shape up, down, or from side to side; it has no effect on how it appears.
We have a transformations maps LMN to L'M'N'.
As the size of Triangle L'M'N' is larger as compared to LMN.
The compression is represented by a scale factor with an absolute value between 0 and 1, while the enlargement is represented by a scale factor with an absolute value greater than 1.
Thus, dilation with a scale factor greater than 1 and then a translation.

In the past 4 months, Alex has lost 8 pounds, gained 9 pounds, lost 2 pounds, and lost another 6 pounds. Find his total change in weight.
please provide with strategies!! ❤️
=============================================================
Explanation:
Draw a vertical number line. Let's say we start at 0 on the number line. Zero means no net change (he doesn't gain weight, nor does he lose weight either).
Losing 8 pounds means we go down 8 units. Think of it like being at the ground level and then going down 8 floors to the basement level of a large building (eg: parking garage maybe).
After this movement, we're at -8 on the number line. Then move up 9 units to arrive at +1 or just 1 on the number line. So Alex has gained those 8 pounds back to his original weight, plus an extra pound. So that's why -8+9 = 1.
Then move down 2 units to get to -1. Lastly, from -1 move 6 units down to get to -7.
So overall, Alex has lost 7 pounds when everything is said and done.
Refer to the diagram below. We start at point A, move to point B after losing 8 pounds, then to C when gaining 9 pounds, and so on until we get to point E. Point E is at -7 on the vertical number line to represent that he lost 7 pounds.
----------------
We can think of it in another way:
add up all the losses to get
loss of 8 + loss of 2 + loss of 6 = loss of 16
So he lost 16 pounds if we ignore the "gained 9 pounds", but we have to account for that. So we'll take 9 away from 16 to get 16-9 = 7.
Overall, Alex lost 7 pounds.

Answer:
5/12 hour or 25 minutes
Step-by-step explanation:
The formula is
distance = rate * time
changing minutes to hours (50 * 1 /60 ) = 5/6 hours
distance = 20 mph * 5/6 hours
distance = 50/3 miles
We need to go the same distance at 40 mph
50/3 = 40 mph * time
Multiply each side by 1/40
50 /3 * 1/40 = 40 * 1/40 *t
50/3 *1/40 =t
5/12 of an hour
Changing back to minutes
5/12 * 60 =25
