Answer:
First Side = 21 units
Second side = 21 units
Third side = 21 units
Step-by-step explanation:
Here, the three sides of the equilateral triangle are:
(2 x-7) cm , ( x + y - 9) cm and ( y + 5) cm
Now, a triangle is said to be an EQUILATERAL TRIANGLE if all three sides of the triangles are equal in the measure.
⇒ For the given triangle to be equilateral:
(2 x-7) = ( x + y - 9) = ( y + 5)
Consider third and second term, we get:
x + y -9 = y + 5
or, x - 9 = 5
⇒ x = 9 + 5 = 12, or x = 14
Also,from first and second term :
(2 x-7) = ( x + y - 9)
⇒ 2(14) - 7 = (14 + y) - 9
⇒ 28 - 7 -14 + 9 = y
or, y = 16
Hence, First Side = 2 x - 7 = 2(14) - 7 = 21 units
Second side = x + y - 9 = 14+ 16 - 9 = 21 units
Third side = y + 5 = 16 + 5 = 21 units

If the adult dosage of the medicine is 180 milligrams (mg), what is 1/3 of the adult dose?
The 1/3 of the adult dosage of the medicine will be 60 milligrams(mg).
What is a fraction?A fraction is a number that is less than 1.
For example, a number 0.5 than is called a fraction number because it is less than 1.
Given that the adult dosage of the medicine is 180 milligrams(mg).
The 1/3 of the 180 milligrams(mg) will be
⇒ 180×1/3
⇒ 60 hence, 60 milligrams(mg) is one-third of adult dosage.

#SPJ2
To find 1/3 of the adult dosage of 180 mg, you simply divide by 3, which results in a dose of 60 mg. This method ensures safe and accurate medication dosing.
If the adult dosage of the medicine is 180 milligrams (mg), then 1/3 of the adult dose can be calculated by dividing the adult dose by 3. So, you would perform the following calculation:
1/3 of 180 mg = 180 mg / 3 = 60 mg.
Therefore, 1/3 of the adult dosage of the medicine is 60 mg.

The graph of this relationship is a ______.
The slope of the graph is ______.
Step-by-step explanation:
y = mx + b
Your equation is y = 3/5x, which means you're "missing" the B
Whichhhhh, just means you're starting at (0,0)
Now, m represents the slope. So your slope was given right off the bat, 3/5.You start at (0,0) and you count up 3, and right 5. Or you could do down 3 and left 5This gives you a line with a slope of 3/5Hopefully my drawing kind of explains it better

16 factory workers made 40 pieces in a certain amount of time.
a)Do these quantities (number of workers and number of pieces produced) vary directly or inversely?
b)Find the constant of variation.
a) The quantities vary directly
b) The constant of variation is 2.5
Step-by-step explanation:
Lets us revise the direct and inverse variation
If y varies x directly, then y = kx, that means the ratio between them is constant ( [tex]\frac{y}{x}=k[/tex] ) , they increased together and decreased together, k is the constant of variationIf y varies x inversely, then yx = k, that means when x increased y must be decrease ( [tex]y=\frac{k}{x}[/tex] ) k is the constant of variation∵ 16 factory workers made 40 pieces in a certain amount of time
- If the number of worker increased, then the number of pieces
increased in the same certain time, if the number of worker
decreased, then the number of pieces also decrease in the
same certain time
∴ The the number of workers and the number of pieces produce
vary directly
∴ Number of pieces produced = k × number of worker
a) The quantities vary directly
∵ The number of worker = 16
∵ The number of pieces produced = 40
- Substitute these values in the equation of variation above
∴ 40 = k × 16
- Divide both sides by 16
∴ k = 2.5
b) The constant of variation is 2.5

In △ABC, point P∈AB so that AP:BP=1:2. Point R ∈ PB that PR:BR=1:2. Point Q∈BC so angle BQR = angle BCP. Find ratio of PQC to ABC.
Answer:
Ratio of PQC to ABC is 2:9.
Step-by-step explanation:
In ΔBRQ and ΔBPC
∠BQR = ∠BCP (given) and ∠B is common for both triangles, so from AAA similarity ΔBRQ and ΔBPC are similar.
⇒ BQ : QC = BR : RP = 2 : 1 →(1)
now draw perpendiculars from points A and P to BC line segment. Call the projected points as A' and P'.
It is clear that lines AA' and PP' are parallel. So in ΔBPP' and ΔBAA' we have AAA similarity with common angle at B.
⇒PP' : AA' = BP : BA = 2 : 3 →(2) (∵ AP : PB = 1 : 2)
area of ΔPQC = 0.5×PP'×QC
area of ΔABC = 0.5×AA'×BC
area of ΔPQC : area of ΔABC = (0.5×PP'×QC)/(0.5×AA'×BC)
=(PP'/AA')×(QC/BC)
=(2/3)×(1/3) (∵ from (1) and (2))
=2/9.
∴ Ratio of PQC to ABC is 2:9

24. Jack's mother is 44 years old. She is 4 years older than 8 times Jack's age. The
equation 8a + 4 = 44 represents this situation.
How old is Jack?
A. 5
B. 6
c. 9
d.13
Answer:
Jack is five. so, it's A
Step-by-step explanation:
subtract 4 from both sides of the equation. You can cancel out the four on the left, and get 40 on the right (since you took four away from 44.)
Then, divide by 8 on both sides. The eight is canceled out on the left. eight goes into 40 five times, meaning a=5.
The correct option is (A) 5. To find Jack's age, subtract 4 from both sides of the equation 8a + 4 = 44 and then divide by 8. This results in a = 5, meaning Jack is 5 years old.
To solve the given equation, 8a + 4 = 44, for Jack's age, we first need to isolate the variable a, which represents Jack's age. This can be done by first subtracting 4 from both sides of the equation to undo the addition.
8a + 4 - 4 = 44 - 4
8a = 40
Next, we divide both sides of the equation by 8 to undo the multiplication and solve for a:
8a / 8 = 40 / 8
a = 5
Therefore, Jack's age is 5 years old, which corresponds to option A.

Point M is located at (-6, 6) What is located 5 units from point M
The points located 5 units from the point M (-6, 6) are (-1, 6), (-11, 6), (-6, 11) and (-6, 1).
To find a point located 5 units from point M in any direction, you can use the coordinates of point M and adjust them based on the distance.
If point M is located at (-6, 6), and you want a point 5 units away, you can choose a direction (left, right, up, or down) and adjust the coordinates accordingly.
For example, if you want a point 5 units to the right of M, you add 5 to the x-coordinate:
[tex]x_{new[/tex] = -6 + 5 = -1
So, a point located 5 units to the right of M is (-1, 6).
If you want a point 5 units to the left of M, you subtract 5 from the x-coordinate:
[tex]x_{new[/tex] = -6 - 5 = -11
So, a point located 5 units to the left of M is (-11, 6).
Similarly, the y-coordinate can be modified for points 5 units above or below M.
For example, if you want a point 5 units to the top of M, you add 5 to the y-coordinate:
[tex]y_{new[/tex] = 6 + 5 = 11
So, a point located 5 units to the top of M is (-6, 11).
If you want a point 5 units to the bottom of M, you subtract 5 from the y-coordinate:
[tex]y_{new[/tex] = 6 - 5 = 1
So, a point located 5 units to the bottom of M is (-6, 1).
If a certain brand of icecream is 99% fat free, how many cups would you have to eat to ingest the same amount of fat that would be in 1 cup of regular icecream?
Answer:
10,000 cups
Step-by-step explanation:
Direct proportional quantities are such that their quotients are always the same number. Example: If I need one cup of sugar to prepare 5 candies, I will need 2 cups of sugar to prepare 10 candies. The quotient 5/1 is equal to the quotient 10/2
Let's suppose a cup of regular ice cream would have 100 parts of fat.
The brand of ice cream mentioned in the question is 99% fat-free which means for every cup of their ice cream, we'll only get 1 part of fat. The relation is 100/1.
If we wanted 100 parts of fat out of fat-free ice cream we would need 100*100/1=10,000 cups of it
These numbers won't change if we used another number instead of 100 in the example shown.
• What is the solution to 5x+ 20 = 7(x+2)?
For this case we must find the solution of the following equation:
[tex]5x + 20 = 7 (x + 2)[/tex]
Applying distributive property on the right side of the equation we have:
[tex]5x + 20 = 7x + 14[/tex]
Subtracting 7x from both sides of the equation:
[tex]5x-7x + 20 = 14\\-2x + 20 = 14[/tex]
Subtracting 20 from both sides of the equation:
[tex]-2x = 14-20[/tex]
Different signs are subtracted and the major sign is placed.
[tex]-2x = -6[/tex]
Dividing between -2 on both sides of the equation:
[tex]x = \frac {-6} {- 2}\\x = 3[/tex]
Thus, the solution of the equation is[tex]x = 3[/tex]
Answer:
[tex]x = 3[/tex]

A student cost for last semester at her community college was 2000.She spent $220 of that on books.what percent of last semester college costs was spent on books??
11% of college costs was spent on books.
Step-by-step explanation:
Total cost for last semester = $2000
Amount spent on books = $220
Percent of amount spent on books = [tex]\frac{Amount\ spent\ on\ books}{Total\cost\ for\ semester}*100[/tex]
Percent of amount spent on books = [tex]\frac{220}{2000}*100\\[/tex]
Percent of amount spent on books = [tex]\frac{22000}{2000}[/tex]
Percent of amount spent on books = 11%
