Answer:
AC equals CB times CD all over CE
The lengths of the sides of the scaled drawing can be determined from the
relation between similar triangles.
The expression that will help Jolene determine the length segment AC is the option;
[tex]\displaystyle \underline{CD= \frac{CB\cdot CD}{CE}}[/tex]Reasons:
The given parameters are;
The figure Jolene is trying to create = A scaled up blue print
Given that in ΔACB and ΔABC, we have;
DE and AB are parallel
Therefore;
∠CED ≅ ∠CBA by corresponding angles
∠CDE ≅ ∠CAB by corresponding angles
∠C ≅ ∠C by reflexive properties
ΔCDE ~ ΔACB by Angle-Angle similarity postulate
Therefore, by similar triangles, and triangle proportionality, we have;
[tex]\displaystyle \frac{AC}{CD} = \mathbf{\frac{CB}{CE}}[/tex]
Therefore;
[tex]\displaystyle CD= \mathbf{ \frac{CB\cdot CD}{CE}}[/tex]
Therefore, if segments DE and AB are parallel, the expression that will help Jolene determine the length segment AC is; [tex]\displaystyle CD= \frac{CB\cdot CD}{CE}[/tex]

Help! What can we do to kill off the zombies?? The scientists realize that salt kills the zombies, if enough is poured on them (one full can). The reaction between the salt and zombie blood causes the zombie to disintegrate. Morton's salt has a plant in Tooele county just west of Grantsville, and can distribute cans of salt to people residing in Utah. If Morton's salt can distribute 300,000 cans of salt each day, write an equation to model the number of cans of salt distributed after n days.

Musi measured the length and width of a soccer field and then made a drawing of the soccer field . He decided to use 1 mm on his ruler to represent 3 m on the soccer field. If his measurement of the width of the soccer field was 63m , what is the width of his drwaing?
If his measurement of the width of the soccer field was 63m , the width of Musi's drawing for a 63 m wide soccer field is 21 mm.
Musi's ruler represents 1 mm as 3 m on the soccer field. To find the width of his drawing for a 63 m wide soccer field, we can set up a proportion to relate the real width to the width on his drawing.
Let "x" represent the width of his drawing in millimeters.
The proportion can be set up as follows:
1 mm (on the drawing) / x mm (real width on the field) = 3 m (on the drawing) / 63 m (real width on the field)
Now, cross-multiply and solve for "x":
1 * 63 m = 3 * x mm
63 = 3x
Divide both sides by 3 to find the width of his drawing:
x = 63 / 3
x = 21
So, the width of Musi's drawing for a 63 m wide soccer field is 21 mm.
In summary, Musi used a scale of 1 mm to represent 3 m on the soccer field. Therefore, the width of his drawing for a 63 m wide soccer field is 21 mm.

Answer:
1. Enlarge, Shrink
2. Smaller
3. Bigger
Step-by-step explanation:
Dilation is something expanding or shrinking, like how your eyes dilate.
Simply think of the scale factor as what you are multiplying the entire figure by. If you are multiplying it by let's say 2, it would double in size, thus getting larger. If you were to multiply it by 1/2, then it would decrease, or shrink, to half its original size.
Answer:
1: enlarge, shrink
2: smaller
3: bigger

Maria started her savings account with $105. she adds $10 to it each month, including the first month. Jana Rae started her account with $0 she adds $25 to it each month. after how many months will the girls have the same amount in their accounts? how much will they have?
Answer:
After 7 months, the girls will have the same amount in their accounts. They will have 175.
Step-by-step explanation:
Maria:
Starts with $105
Adds $10 each month
Jana Rae:
Starts with $0
Adds $25 each month
Set up an equation for both Maria and Jana.
m will represent the number of months.
Maria: 105 + 10m
Jana: 0 + 25m
You can do guess and check.
Let’s say m is equal to 6.
Subsitute m with 6 for both equations and check if they both end up having the same answer.
Maria: 105 + 10(6) = 165
Jana: 0 + 25(6) = 150
Is 165 and 150 equivalent? No
Let’s try m = 7 and do that same thing.
Maria: 105 + 10(7) = 175
Jana: 0 + 25(7) = 175
Now is the answer equal? Yes
So therefore, after 7 months, the girls will have the same amount in their accounts. They will have 175.

Ms. Dirr is selling her car to her sister. The original price of the car was $24,179 and
each year the car decreasing (goes down) by $3000. Write a function rule where C =
value of the car and y = number of years
O C = 3000 - 24179y
O C = 24179 - 3000y
O C = 3000 + 24179y
OC - 24179 + 3000y
Answer: 24,179 - 3000y
Step-by-step explanation: Each year the car goes down by 3000 since you said it was decreasing, so y represents the year and you eould out it next to the 3000 to represent that 3000 is being decreased every year.

Explain why it does not matter which point you choose when writing the
equation of the line in point-slope form, given two points.
Answer:
because, it will completely change the slope
Step-by-step explanation:
It does not matter which point you choose when writing the
equation of the line in point-slope form because the slope of the line remains same.
What is a slope ?A slope can be thought of as rate of change of y axis with respect to x axis.
We have been asked in this statement that why it doesn't matter that which point we choose when writing the equation in point slope form.
Let us understand this with an example,Suppose we have two pair of points. (x₁,y₁) = (2,3) and (x₂,y₂) = (5,9).
We know slope(m) is = (y₂-y₁)/(x₂-x₁).
Slope(m₁) = (9-3)/(5-2)
= 6/3
= 2.
Now if interchange the points (x₁,y₁) = (5,9) and (x₂,y₂) = (2,3).
Slope(m₂) = (3-9)/(2-5)
= -6/-3
= 2.
So, even when interchanging the points the slope m₁ = m₂ this is the reason why it doesn't matter which point we choose.

c)If you receive an extra money of $9.50 from people, then how much will be saved for each group?(Include all the groups)
Answer:
a) there are three groups here
total cash = $120.50
each group takes = $120.50 / 3
each group have = $40.17
b) Total no of groups = 4
Total cash = $120.50
each group takes = $120.50 / 4
Each group have = $30.13

What is the slope of the line that passes through the points (-4,-2) and (-4,22)
Answer:

Step-by-step explanation:
( x1, y1 ) = ( - 4, - 2 )
Here,
x1 = - 4
y1 = - 2
( x2, y2 ) = ( - 4, 22 )
Here,
x2 = - 4
y2 = 22
Formula : -

Find the missing side of each triangle. Round your answers to the nearest tenth if necessary. (Please Show)
Answer:
x = 12.2 mi
Step-by-step explanation:
Given the two sides of the right triangle:
a = 6.1 mi
b = 10.6 mi
c = x
Use the Pythagorean Theorem to solve for the value of the hypotenuse, x:
c² = a² + b²
c² = (6.1)² + (10.6)²
[tex]\sqrt{(c^{2})} = \sqrt{37.21 + 112.36}[/tex]

Tiffany is filling her daughter's pool with water from a hose. She can fill the pool at a rate of 1/10 gallons per second.
Create at least three equivalent ratios that are associated with the rate. Use a double number line to show your work.
The three equivalent ratios are 6/1 gallons/minute, 1/40 quarts/second and 360/1 gallons/hour.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given that, Tiffany can fill the pool at a rate of 1/10 gallons per second.
Equivalent ratios are the ratios that are the same when we compare them.
We know that, 60 seconds =1 minute
1/10 × 60 = 6 gallons/minute
1 gallon = 4 quarts
1/10 = 1/10×4 = 1/40 quarts/second
1 hour =60 minute
So, 6 gallons/minute =6×60
= 360 gallons/hour
Here, 6 gallons/minute = 1/40 quarts/second = 360 gallons/hour
Therefore, the three equivalent ratios are 6/1 gallons/minute, 1/40 quarts/second and 360/1 gallons/hour.
