What is a right-angle triangle?A right-angle triangle is a triangle that has a right-angle.
Here, the sides of the triangle are 5, 10, and 12.
As per Pythagorean theorem for a right-angle triangle,
(Base)² + (Height)² = (Hypotenuse)²
Now, for the given triangle:
[tex](5)^{2} + (10)^{2}[/tex]
[tex]= 25 + 100\\= 125\\= 11.18[/tex]

Which system of equations could represent this situation, using variables to represent the number coins? x+y=11 and 25x+5y=265; x= number of quarters and y= number of nickels. x+y=12 and 25x+5y=265; x= number of quarters and y= number of nickels. x+y=13 and 25x+10y=265; x= number of quarters and y= number of dimes. x+y=12 and 25x+10y=265; x= number of quarters and y= number of dimes.
Answer:
x+y=13 and 25x+10y=265;
x= number of quarters and y= number of dimes.
Step-by-step explanation:
marked as right
The solution is Option A and Option C.
x + y = 11 and 25x + 5y = 265
x = number of quarters and y = number of nickels
x + y = 13 and 25x + 10y = 265
x = number of quarters and y = number of dimes
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total amount be A = $ 2.65
The value of 1 nickel = $ 0.05
The value of 1 dime = $ 0.10
The value of 1 quarter = $ 0.25
Now , the equation will be
a)
x + y = 11 and 25x + 5y = 265
x = number of quarters and y = number of nickels
On simplifying the system of equations , we get
25x + 5y = 265 be equation (1)
5x + 5y = 55 be equation (2)
Subtracting (2) from equation (1) , we get
20x = 210
x = 10.5
So , the value of y = 0.5
Substituting the value of x and y in equation (1) , we get
25 ( 10.5 ) + 5 ( 0.5 ) = 265
262.5 + 2.5 = 265
265 = 265
Therefore , the system of equations satisfies the conditions
c)
x + y = 13 and 25x + 10y = 265
x= number of quarters and y= number of dimes
On simplifying the system of equations , we get
25x + 10y = 265 be equation (1)
10x + 10y = 130 be equation (2)
Subtracting (2) from equation (1) , we get
15x = 135
x = 9
So , the value of y = 4
Substituting the value of x and y in equation (1) , we get
25 ( 9 ) + 10 ( 4 ) = 265
225 + 40 = 265
265 = 265
Therefore , the system of equations satisfies the conditions
Hence , The solution is Option A and Option C.
x + y = 11 and 25x + 5y = 265
x = number of quarters and y = number of nickels
x + y = 13 and 25x + 10y = 265
x = number of quarters and y = number of dimes

Median
Your answer
Answer:19
Step-by-step explanation:
17,18,18,19,21,22,46
The median of the given sequence i.e. 17,18,18,19 21,22,46 should be considered as the 19.
Calculation of the median:Since the given sequence is 17,18,18,19 21,22,46
There is total 7 numbers
So for that we have to apply the below formula
[tex]= ( n + 1) \div 2 \\\\= ( 7 + 1) \div 2\\\\= 8 \div 2[/tex]
= 4th term

Assume that y varies directly with x, then solve.
if y=-6.6 when x=9.9, find y when x=6.6
Answer:
y = - 4.4
Step-by-step explanation:
Given that t varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 6.6 when x = 9.9 , that is
- 6.6 = 9.9k ( divide both sides by 9.9 )
k = [tex]\frac{-6.6}{9.9}[/tex] = - [tex]\frac{2}{3}[/tex]
y = - [tex]\frac{2}{3}[/tex] k ← equation of variation
When x = 6.6, then
y = - [tex]\frac{2}{3}[/tex] × 6.6 = - 2 × 2.2 = - 4.4
Emily and John each ran at a constant speed for a 100-meter race. Emily gave John a 10-meter head start. Use the given data below to determine who won the race and by how many seconds
Answer:
Emily won the race; she finished 1.9 seconds ahead of John.
Note: The question is incomplete. The complete question is given below:
Emily and John each ran at a constant speed for a 100-meter race. Emily gave John a 10-meter head start. Use the given data below to determine who won the race and by how many seconds.
John's run
A 2-column table with 4 rows. Column 1 is labeled Time (seconds) with entries 4, 6, 8, 10. Column 2 is labeled Distance (meters) with entries 35, 47.5, 60, 72.5.
Emily's run
A graph titled Emily's Run has time (seconds) on the x-axis and Distance (meters) on the y-axis. Points are at (4, 32), (6, 48), (8, 64), and (10, 80)
Step-by-step explanation:
Step 1: Since, they ran at a constant speed, first, we calculate John's speed ;
Speed = (change in distance)/(change in time)
John's Speed = (72.5 - 60)/(10 - 8) = 6.25 m/s
Step 2: Then, we calculate Emily's speed;
Speed = (change in distance)/(change in time)
Emily's Speed = (80 - 64)/(10 - 8) = 8.00 m/s
Also, it was stated that Emily gave John a 10 m head start, therefore, John ran a distance of 90 m at 6.25 m/s while Emily ran a distance of 100 m at 8.00 m/s
Step 3: Time taken by both runners
Time = (Distance/Speed)
Time taken by John; time = (90/6.25) = 14.4 s
Time taken by Emily, Time = (100/8.00) = 12.5 s
Therefore, Emily won the race since her time to complete the race was shorter. She won the race by (14.4 - 12.5) = 1.9 s
Emily and John each ran at a constant speed for a 100-meter race. Emily gave John a 10-meter head start. Use the given data below to determine who won the race and by how many seconds.
✔ Emilywon the race by about
✔ 2seconds.

The sum of the smallest prime number and the second smallest prime number is divided by the third smallest prime number.
To find:
The remainder.
Solution:
Prime numbers are the numbers which are divided by only 1 or itself.
Smallest prime number = 2
Second smallest prime number = 3
Third smallest prime number = 5
The sum of the smallest prime number and the second smallest prime number is divided by the third smallest prime number.

Since 5 is completely divided by 5, therefore, t he remainder is 0.
Pls Help me I am really stuck 10 points
Answer:
2) x=6 3) x=4 m<EFH=21 m<EFG=83
Step-by-step explanation:
2) Basically they're giving you two parts of a whole angle. The entire angle is 127 degrees, split into two parts. one part being 83 degrees and the other is (9x-10). the way you solve for X is by making it into an equation. Angle JKM + angle MKL = angle JKL. So substitute the values they gave you into the one we just made.
(9x-10) + 83 = 127 then solve for x.
9x-10+83=127
9x+73=127
9x=54
x=6
3) this question is the same thing but now theres a variable on both sides of the equation. angle EFH +angle HFG = angle EGF. substitute then solve for x
(5x+1) + 62 = 18x+11
5x+63=18x+11 move the x variables to one side
52=13x
x=4
for the rest of the angles just plug in the x value to the equations for the smaller angles
m<EGF:
18x+11
18(4)+11= 83
m<EFH
5x+1
5(4)+1= 21
