The hypotenuse of a right-angled triangle is 61 cm. If one of the remaining two sides is
11cm, find the length of other side.
Answer:
60cm
Step-by-step explanation:
the length of other side = sqrt (square root) hypotenuse^2 - the length of thrid side^3 = sqrt 61^2 - 11^2 = sqrt 60^2 = 60

Find the missing side of this right
triangle.
17
X
15
x=
Answer:
We can fine x by using the pythagoras formula
a²+b² = c²
Which C is X
And
a= 17
b= 15
So
a² + b² = c²
(17)² + (15)² = c²
289 + 225 = c²
514 = c²
√514 = c
22.67 = c
So basically X is (22.671)
The missing side of the given right angled triangle is 8 units.
In the given right angled triangle, the hypotenuse side is 17 units, base is 15 units and the height is x units.
By using Pythagoras theorem, we get
17²=15²+x²
289=225+x²
x²=289-225
x²=64
x=√64
x=8 units.
Therefore, the missing side of the given right angled triangle is 8 units.

The sum of two integers is 21. Fifteen less than double the square of the smaller integer is equal to the larger
integer. What are the two numbers?
Answer:
2x^2+x-36=0
(4,0)
2*4^2+4-15=21
Step-by-step explanation:
The addition is one of the four fundamental mathematical operations. The two integers are 4 and 17.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
Let the two unknown integers be represented by x and y, where x
Given that The sum of two integers is 21. Therefore, we can write,
x + y = 21
y = 21 - x
Also, Fifteen less than double the square of the smaller integer is equal to the larger integer.
2(x²) - 15 = y
Substitute the value of y from the first equation,
2(x²) - 15 = 21 - x
2x² - 15 = 21 - x
2x² + x - 15 - 21 = 0
2x² + x - 36 = 0
2x² + 9x - 8x - 36 = 0
x(2x + 9) -4(2x + 9) = 0
(x-4)(2x+9) = 0
x = (-9/2), 4
Since it is given that the number are integers, therefore, the only option is 4.
Further, the two integers are,
x = 4
y = 21 - x = 21 - 4 = 17
Hence, the two integers are 4 and 17.

Without stopping, Beth then travels 70 miles in 1.5 hours.
Find her average speed for the entire journey to 2 dp.
Answer:
41.54 mph
Step-by-step explanation:
you need to find the total distanceand total time to find the average speed
use distance/time = speed equation
time = 1.5 hours + 40 mins = 2 hours 10 mins
distance= 20 + 70 = 90 miles

So, based on my knowledge, you are learning the Distributive probability. So, what the Distributive property does is it basically allows to distribute the one of the numbers in the multiplication problem. In this problem, we can see that the 8 is being distributed into two groups of 4 to make (4 * 6) + (4 * 6). Then, we solve the things in the two parenthesis, making 24 + 24. Now, all we have to do is add 24 + 24, making 48.

is this algebra
Step-by-step explanation:
Answer:
1.)
A.) The graph does represent a proportional relationship because if you calculate the slope, it's 2/3, which is consistent throughout the line and with the given points.
Slope calculation:
[tex]\frac{y2-y1}{x2-x1} \\\\\frac{6-4}{9-6} \\\\\frac{2}{3}[/tex]
B.) The coordinate (0,0) represents that no laps have been completed nor has the time started
C.) The coordinate I chose is (6,4). It represents that 4 laps were completed in 6 minutes
2.) The values to represent a proportional relationship because once calculating the slope, which is 13, you can try it with other points. Even though there's some values missing between (6,78) and (10,130), the slope remains the same.
Slope Calculation:
[tex]\frac{y2-y1}{x2-x1} \\\\\frac{130-39}{10-3} \\\\\frac{91}{7} \\\\\frac{13}{1}[/tex]
3.)
A.) The constant of proportionality is 7/4 or 1.75
B.) y = 7/4x
4.) She'll run 8 miles because since 3/4 of an hour equates to 6 miles and there's 1/4 missing, 2 miles is 1/3 of 6 miles and 1/4 is 1/3 of 3/4 , so 1/4+1/4+1/4 = 3/4. She can run 8 miles (4*2) in 1 hour (4*1/4 hour)

200 people got an email 37 people clicked on it how do you get 18.5%
Answer:
37/200
Step-by-step explanation:
Event/Sample Space = .185 = 18.5%
Answer:
Step-by-step explanation:
If 37 people out of 200 people opened an e-mail, you can write it as 37/200.
The number above the bar is the numerator: 37
The number below the bar is the denominator: 200
Divide the numerator by the denominator to get fraction's value:
Val = 37 ÷ 200
Val = 0.185
To calculate the percent value:
0.185 = (Calculate fraction's value.)
0.185 × 100/100 =
(0.185 × 100)/100 = (Multiply that number by 100.)
18.5/100 =
18.5%; (Add the percent sign % to it.)
So that's how you get 18.5%
