Is it possible for any angle A, sinA=7/5Explain.
Answer:
No
Step-by-step explanation:
note [tex]\frac{7}{5}[/tex] = 1.4
and sinA is defined for - 1 ≤ sinA ≤ 1
Thus sinA ≠ [tex]\frac{7}{5}[/tex]

The length of each side of a square is halved. What
fraction of the original perimeter is the new perimeter?
Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Halving the side of the square, results in the perimeter being halved.
new perimeter = [tex]\frac{1}{2}[/tex] original perimeter

Now check your work by using the GeoGebra geometry tool to repeat parts A through D. Open GeoGebra, and complete each step below. If you need help, follow these instructions for using GeoGebra. You will take a screenshot of your work when you are through, so be sure to clearly label your construction as you work.
Plot points A, B, and C, and draw a polygon, ΔABC, through the points.
Draw a line perpendicular to AC¯ through point B.
Label the intersection of the line perpendicular to AC¯ through B and AC↔ point D.
Measure and display the slopes of AC↔ and BD↔.
Display the equations of AC↔ and BD↔ in the Algebra margin.
Measure and display the lengths of AC¯ and BD¯.
Calculate and display the area of ΔABC.
Take a screenshot showing the geometric construction and the Algebra margin, save it, and insert the image in the space below.
Part F
Compare the calculations displayed in GeoGebra with the calculations you completed in parts A through D. Look in the Algebra margin too. Do the results in GeoGebra match the results you obtained earlier? If not, where do the discrepancies occur? You might have to rearrange equations algebraically to determine whether two equations match.
Part G
You’ve seen two methods for finding the area of ΔABC—using coordinate algebra (by hand) and using geometry software. How are the two methods similar? How are they different? Why might coordinate algebra be important in making and using geometry software?

A preschool bought 10 gallons of milk for two classrooms. One week, the first class drank 9 quarts. The second class drank 1/3 that amount.
1 gallon = 4 quarts
How many more quarts must they drink altogether to finish all the milk?
Hello :D
10 gallons = 40 quarts
1/3 = 3 quarts
9 quarts + 3 quarts = 12 quarts
40 - 12 = 28 quarts
They must drink 28 quarts to finish all the milk
-3(x² +2x-3)+3(x²+4x)
6x + 9
I hope this helps!
Answer:
= 6x +9
Step-by-step explanation:
1. you need to multiply -3 by x² + 2x - 3
so you got -3x² -6x + 9
2. Then, you need to multiply 3 by (x²+4x)
= 3x² + 12x
3. -3x² - 6x + 9 + 3x² + 12x
4. then you need to solve with the same
= - 3x² + 3x²
= 0
= - 6x + 12x
= 6x
5. lastly you will got the answer.
# = 6x +9

PLS HELP ME SLOPE INTERCEPT FORMMM
through: (1, -1), parallel to y=5/3x
Step-by-step explanation:
the slope = 5/3
through (1, -1)
the equation :
y -(-1) = 5/3 (x -1)
y+1 = 5/3 x -5/3
y = 5/3 x -5/3 -1
y = 5/3 x - 8/3 or y = 5/3 x - 2⅔

=> f(6) = 12 + 4
=> f(6) = 16
Solve the following equation. Show your work for credit.
3х -40 = 1/2x + 35
Answer:
x=30
Step-by-step explanation:
Let's solve your equation step-by-step.
3x−40=12x+35
Step 1: Subtract 1/2x from both sides.
3x−40−12x=12x+35−12x
52x−40=35
Step 2: Add 40 to both sides.
52x−40+40=35+40
52x=75
Step 3: Multiply both sides by 2/5.
(2/5)*(5/2 x)=(2/5)*(75)
x=30

An equilateral triangle measures 5 by 3/8 cm on one side. What is the perimeter of the traingle
Step-by-step explanation:
in an equilateral triangle all 3 sides have the same length.
so, when one side measures 5 3/8 cm, then all 3 sides have the same length.
this "5 by 3/8 cm" phrasing is strange. normally that would be used for an area giving 2 dimensions. but here it is clearly meant to describe one dimension, length.
so, I can only assume this means the side is 5 3/8 cm long.
the perimeter of the triangle is simply the sum of all ways needed to walk around the whole triangle : the sum of all 3 sides.
we could do this 2 ways (1. convert 5 3/8 into one big fraction and do the calculation, 2. stay with 5 3/8 and do the calculations there).
I think 1. it's easier to understand and to also use it for other similar problems.
so,
5 3/8 = (5×8 + 3)/8 = (40 + 3)/8 = 43/8
we have 3 sides of equal length
Perimeter = 3×43/8 = 129/8 = 16 1/8 cm
One side of the equilateral triangle is given, then the perimeter of the triangle will be equal to 16. (1/8) or 129/8.
What is perimeter?The complete distance around a shape is referred to as its perimeter. It is any two-dimensional geometric shape's perimeter or outline length. Based on the measurements, the circumference of multiple figures may be equivalent.
As per the given data in the question,
One side of the triangle = 5 3/8
= 43/8
All the sides of the equilateral are equal, then,
Perimeter, P = 3 × side
P = 3 × 43/8
P = 129/8 or 16(1/8)
