Answer:
True, we use Pythagorean Theorem to verify if three sides form a triangle
Answer:
false because Pythagoras theorem is used to prove wether the given triangle is right angled or not whereas we need to make the sum of each angles Nd if it becomes 180 then we can proclaim that the given figure is a triangle

Amy bought x pencils at RM 0.60 each and y erasers at RM0.40 each. She sells the pencil at
RM0.85 each and the eraser at RM0.60 each. Write an algebraic expression for Amy's total profit,
in sen.
Answer:
Profit = 0.25x + 0.20y
Step-by-step explanation:
cost price of 1 pencil = RM 0.60
So, C. P. of x pencils = 0.60x
Similarly,
C. P. of y erasers = 0.40y
Total C. P. = 0.60x + 0.40y
Selling Price of x pencils = 0.85x
S. P. of y erasers = 0.60y
Total S. P. = 0.85x + 0.60y
Profit = Total S. P. - Total C. P.
= (0. 85x + 0.60y) - (0.60x + 0.40y)
= 0. 85x + 0.60y - 0.60x - 0.40y
= 0.85x - 0.60x + 0.60y - 0.40y
Profit = 0.25x + 0.20y

Emma needed a loan of $600 for repairs to her house. The bank loaned her the money at 10% interest for 2 years. What is the total amount of the loan?
Answer:
$720
Step-by-step explanation:
10% x 2 (since it's 2 years)
20% of 600 = 120
600 + 120 = 720
2x - 5y + 3z = 27
4x + 3y - 7z=-37
x - 2y + 5z = 30
I need help solving this with cramers rule
Step-by-step explanation: answer {x,y,z} = {1,-2,5}
/ Solve equation [3] for the variable x
[3] x = 2y - 5z + 30
// Plug this in for variable x in equation [1]
[1] 2•(2y-5z+30) - 5y + 3z = 27
[1] - y - 7z = -33
// Plug this in for variable x in equation [2]
[2] 4•(2y-5z+30) + 3y - 7z = -37
[2] 11y - 27z = -157
// Solve equation [1] for the variable y
[1] y = -7z + 33
// Plug this in for variable y in equation [2]
[2] 11•(-7z+33) - 27z = -157
[2] - 104z = -520
// Solve equation [2] for the variable z
[2] 104z = 520
[2] z = 5
// By now we know this much :
x = 2y-5z+30
y = -7z+33
z = 5
// Use the z value to solve for y
y = -7(5)+33 = -2
// Use the y and z values to solve for x
x = 2(-2)-5(5)+30 = 1
HELP What's greater -1 17/20 or -1 8/10
Use < or >
Answer:
The answer is -1 17/20 < -1 8/10.
Step-by-step explanation:
If you would calculate it to decimal, you should get:
a) -1 17/20= -1.85 or can be -37/20
b) -1 8/10= -1.8 or can be -9/5 or -1 4/5
As you can see, -1 8/10 has a larger decimal value so the answer would be -1 17/20 < -1 8/10.
Hope this helps and if you can mark this as brainliest. Thanks
Answer:
-1 17/20 < -1 8/10
Step-by-step explanation:

Answer:
A is smaller
Step-by-step explanation:
The surface area of a cylinder is ...
A = 2πr² +2πrh = 2πr(r+h)
Here, we have r=30 mm, h = 240 mm, so the surface area is ...
A = 2π(30 mm)(30 +240 mm) = 60,200π mm² ≈ 50,894 mm²
__
The box is 2 diameters square and 1 diameter high. Its surface area is ...
A = 2(LW +H(L+W)) = 2((120 mm)(120 mm) +(60 mm)(120 +120 mm))
A = 2(14400 mm² +14400 mm²) = 57,600 mm²
Comparing the two areas, we conclude that ...
A is smaller
_____
Alternate solution
Since r = d/2, the area of the cylinder is ...
A = 2π(d/2)(d/2 +4d) = 9πd²/2 ≈ 14.14d²
The area of the box is ...
A = 2((2d)(2d) +d(2d +2d)) = d²(2(4 +4)) = 16d²
Then 14.14 < 16, so A is smaller.

sandy and Selena both sell bracelets that they make. Sandy spent $25 on her materials to start and sells her bracelets for $10. Selena spent $73 on her materials and sells her bracelets for $26
After how many bracelets will the money taken in (y) and the number of bracelets sold (x) be the same for the girls?
Answer:
After 3 bracelets , the money taken in and the number of bracelets sold will be the same for the girls
Step-by-step explanation:
Let the number of bracelets that makes the amount of profit made be equal be x
For Sandy, her gain will be 10x - 25
For Selena, her gain will be 26x - 73
So equating both, we can find x
10x - 25 = 26x - 73
26x-10x = 73-25
16x = 48
x = 48/16
x = 3
To get the amount, we can make a substitution for x
we have;
10(3) - 25 = 30-25 = $5

Answer:
x=20
Step-by-step explanation:
The line equal 180 degrees, and we already know one angle so, 180-80=100. The two missing angles are equal to 100 so add them up and divide by 5.
2x + 3x =100
5x=100
x=20
which expression is not equal to 30
(9 x 10) + (4+1) + 12
2+(30-8÷4)

Lakita wants to go to trade school and study electronics for a two-year program. Her tuition and books will cost about $5,500 per year. She will also spend about $100 a month commuting from her parents’ house to school. How much will her education cost her in total?
Answer:
$13,400Step-by-step explanation:
Step one:
let us first compute the tuition and books for the two years
we are told that the tuition is $5,500 per year
For the two years,the tuition will be 5,500*2= $11,000
Step two:
we need to calculate the cost of transportation for the two years also
in two years there are 24 months
if Lakita will spend $100 per months
then in 24 months Lakita will spend= 24*100= $2400
Hence her education cost her in total is
=$11,000+$2400
=$13,400

Answer:
We can use the SAS. (B)
Step-by-step explanation:
- The triangles have a side in common (XZ): SIDE (S)
- Also, the triangles XWZ and XYZ have a right angle in the vertex Z: ANGLE (A)
- Lastly, the sides WZ and ZY have the same lenght, since they're marked with the same signal: SIDE (S)
So, the postulate SAS (side-angle-side) can be directly used to determine that XWZ and XYZ are congruents. Hence, the answer is the alternative B.
