Zelie planned for a square pool to have a side length of 28 ft but found that it needs to be 14 ft long to fit in her backyard. She found the change of scale below. StartFraction 28 feet minus 7 over 14 feet minus 7 EndFraction = StartFraction 21 over 7 EndFraction Which is Zelie's error? Zelie should have divided both numbers by 14. Zelie should have written the ratio as StartFraction 28 feet over 7 feet EndFraction. Zelie should have written the ratio as StartFraction 14 feet over 28 feet EndFraction.
Answers
Answer:
Zelie should have divided both numbers by 14
Step-by-step explanation:
Given
[tex]Actual = 28[/tex]
[tex]Measured = 14[/tex]
Required
Spot and correct Zelie's mistake
[tex]Zelie = \frac{28 - 7}{14 - 7} = \frac{21}{7}[/tex]
Scale is calculated as:
[tex]Actual = Measured * Scale[/tex]
[tex]28 = 14 * Scale[/tex]
Divide 28 and 14 by 14
[tex]28/14 = 14/14 * Scale[/tex]
[tex]2 = 1 * Scale[/tex]
[tex]2 =Scale[/tex]
[tex]Scale = 2[/tex]
Notice at this point:
[tex]28/14 = 14/14 * Scale[/tex]
Both sides were divided by 14.
Hence, option A answers the question.

A. Zelie should have divided both numbers by 14.

There are 2 overlapping triangles here. If the vertical lines are parallel, then these triangles are similar, and corresponding sides occur in a fixed ratio. In particular, we have
2/3 = (2 + x) / (3 + (x + 7))
Solve for x :
2/3 = (2 + x) / (10 + x)
2 (10 + x) = 3 (2 + x)
20 + 2x = 6 + 3x

Write equation in slope intercept form (x=mx+b). Find the slope (x) and the y-intercept (b) of the line
Answers
Answer:
y = (2/3)x - 1
Step-by-step explanation:
By refering the graph, we can see that y-intercept(b) = (a point of the y-axis) which is -1.
the coordiates i have taken:
(-3 , -3) ------ (-3 =x1, -3 =y1)
and
( 3, 1 ) --------( 3 = x2, 1 = y2)
To find slope,
slope(m) = rise/run = ( y2 - y1 ) / ( x1 - x2 )
=> ( 1 - (-3) ) / ( 3 - (-3) ) -----( negative × negative = positive. Hence the signs are positive. )
=> ( 1 + 3 ) / ( 3 + 3 )
=> 4 / 6
=> 2 / 3 ------(simplied after numerator and denominator got divided by 2)
now,
b = -1
m = 2/3
x = x ----(x remains same)
Therefore,
y=> mx + b
by substituting the values, we get,
y=> (2/3)x - 1

3. The area of a rectangle is 5/8 square foot. The width of the rectangle is 24
feet. What is the length of the rectangle?
a) 25/16 feet
b) 25/5 feet
c) 14 feet
d) 4 feet
Answers
Answer: 14
Step-by-step explanation:
Well, we know that the formula to fugure out area is :Length times Width
We also know that WIdth is 24. So 24 times __ =5/8.
Now, how do you figure out __? Well, let's first replace that as a variable to make it easier. Let's choose: x Now, we know that:
x * 24 = 5/8.
To figure out x, we need to do 5/8 divided by 24, right? When you solve that, the answer would be 15. The closest is 14, so I think the answer is 14.

HELP WITH MY MATH EXAM i don't know what to do and my head hurts a lot
Answers
Answer:
x = 154/13
Step-by-step explanation:
You are given the measures of all three angles in a triangle
so according to the Triangle Sum Theorem:
∠MNO + ∠OMN + ∠NOP = 180
1. Substitute the measures of the angles into the equation:
(3x + 11) + (2x + 20) + (8x - 5) = 180
2. Combine like terms:
(3x + 2x + 8x) + (11 + 20 -5) = 180
13x + 26 = 180
3. Isolate x by subtratcing 26 from both sides
13x + 26 -26 = 180 -26
13x = 154
4. Solve for x by dividing both sides by 13
13x/13 = 154/13
x = 154/13
