Which expression gives the length of QR in the triangle shown below?
Answer:
sqrt( 17^2+ 25^2)
Step-by-step explanation:
Since this is a right triangle, we can use Pythagorean theorem
a^2+b^2 = c^2 where a and b are the sides and c is the hypotenuse
Taking the square root of each side
sqrt(a^2+b^2) = QR
sqrt( 17^2+ 25^2) = QR
Answer:
[tex] \small \sf A. \sqrt{25 {}^{2} + 17 {}^{2} } [/tex]
Step-by-step explanation:
Using pythagoras theorem
( Base) ² + ( Perpendicular) ² = (Hypotenuse) ²
( QS)² + ( RS)² = (OR )²
( 25 )² + ( 5 )² = OR²
Taking square root of each side.
[tex] \sqrt{25 {}^{2} + 17 {}^{2} } = \sqrt{OR}[/tex]
[tex] \sqrt{25 {}^{2} + 17 {}^{2} } = {OR}[/tex]
Which one is greater 5.3 or 5 1/3
Answer:
5 1/3 > 5.3
Step-by-step explanation:
1/3 = 0.333... so 5 1/3 > 5.3 as 5 1/3 = 5.333...
The fraction 5 1/3 is greater than 5.3.
What is a fraction?A number expressed as a quotient, in which a numerator is divided by a denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. A fraction represented with its quotient and remainder is a mixed fraction.
For the given situation,
The decimal number is 5.3.
The mixed fraction is 5 1/3.
First, convert this fraction to a decimal number to check which is greater.
[tex]5\frac{1}{3}=\frac{16}{3}[/tex]
⇒ [tex]5.33[/tex]
On comparing these two decimals 5.33 and 5.3, we can conclude that 5 1/3 is greater than 5.3.

Answer:
See answers below
Step-by-step explanation:
Find the diagram attached
To get AB, use the pythagoras theorem;
AB² = 12² + 9²
AB² = 144 + 81
AB² = 225
AB = √225
AB = 15
Since
Hypotenuse = AB
sin <A = BC/AB
Sin <A = 12/15
Sin <A = 4/5
<A = arcsin(0.8)
<A = 53.13degrees
Sin <B = AC/AB
Sin<B = 9/15
Sin <B = 0.6
<B = arcsin(0.6)
<B = 36.87degrees
the interest for 3 years on Rs2400is Rs576 find the interest on Rs 4200 for 2 yrs at the same rate of interest
Answer:
Solution given:
time [t]=3years
principal [p]=Rs2400
rate[r]=?
simple interest [S.I]=Rs 576
we have
S.I=ptr/100
576=2400*3*r/100
576=72r
r=576/72
r=8%
now
principal [p]=Rs 4200
time[t]=2years
rate[r]=8%
simple interest [S.I]=?
we have
S.I= ptr/100=4200*2*8/100=Rs 672
The required interest is Rs 672.

A lock has a 3-number code made up of 16 numbers. If none of the numbers are allowed to repeat, how many different ways can you choose three different numbers in order for a unique code?
Answer:
137
Step-by-step explanation:
The number of ways we can choose three different numbers in order for a unique code for this case is 2730
What is Combination?A combination is a technique to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
We can use combinations for this case,
Total number of distinguishable things is m.
Out of those m things, k things are to be chosen such that their order doesn't matter.
This can be done in total number of ways,
⇒ [tex]^{m} C_{k} =[/tex] m! / (m - k)! k!
If the order matters, then each of those choice of k distinct items would be permuted k! times.
So, total number of choices in that case would be:
⇒ [tex]^{m} P_{k} =[/tex] m! / (m - k)!
This is called permutation of k items chosen out of m items (all distinct).
Given that:
The considered lock as a 3 number code
There are 15 numbers available.
None of the number can repeat.
In a lock, the order of the way numbers are arranged matters.
Because of no repetition allowed, we can simulate this situation as:
The number of ways we can choose 3 numbers out of 15 numbers with order = The number of different ways we can choose three different numbers in order for a unique code.
And we have:
The number of ways we can choose 3 numbers out of 15 numbers with order is,
⇒ [tex]^{m} P_{k} =[/tex] m! / (m - k)!
⇒ [tex]^{15} P_{3} =[/tex] 15! / (15 - 3)!
= 15! / 12!
= 2730
Thus, The number of ways we can choose three different numbers in order for a unique code for this case is 2730

The school events committee is planning to buy a banner and some helium balloons for graduation night. A store charges them $35 for the banner and $3 for each helium balloon. If the committee has at most $125 to spend, how many helium balloons can they buy
Answer:
30 baloons
Step-by-step explanation:
1. Remove the price of the banner from the total amount you can spend. You should then end up with $90
2. Divide 90 by 3, because each balloon costs $3. You should end up with 30.
Answer:
30 balloons
Step-by-step explanation:
Cost of banner = $ 35
Remaining amount after paying for banner = 125 - 35 = $90
Number of balloons = Remaining amount ÷ cost of one balloon
= 90 ÷ 3
= 30
What is the solution to –2(8x – 4) < 2x + 5? x > x is greater than StartFraction 1 Over 6 EndFraction. x < x is less than StartFraction 1 Over 6 EndFraction. x > 6 x < 6
Answer:
x > 1/6.
Step-by-step explanation:
–2(8x – 4) < 2x + 5
-16x + 8 < 2x + 5
-18x < -3
x > 1/6.
The solution to the inequality expression is x > 1/6
Given the inequality expression
–2(8x – 4) < 2x + 5
Expand the parenthesis
-16x + 8 < 2x + 5
Subtract 5 from both sides
-16x + 8 - 5 < 2x + 5 - 5
-16x + 3 < 2x
-16x - 2x < -3
-18x < -3
Divide both sides by -18
-18x/-18 > -3/-18
x > 1/6
Hence the solution to the inequality expression is x > 1/6

The item can be anything really. I'm going to add a trampoline which is a square shown in purple. The square is rotated 45 degrees so it looks like a diamond shape. The rotation isn't necessary but I figured to spice things up compared to the other figures which were mostly squares or rectangles. If we split the purple square into 4 triangles, and apply the pythagorean theorem, then we can find the length of each side of the purple square to be roughly 2.828 cm.
Scaling things up, the trampoline in real life is 2*2.828 = 5.656 meters along each dimension.
With any square the angles are always 90 degrees.

Does anyone know how to solve this?
Given :
A right angle triangle ABC .
To Find :
The perimeter of ABC .
Solution :
Since, triangle ABC is right angled and angle ∠ABC is 46° .
So, AC = AB cos 46° = 7.64 units.
Also, CB = AB sin 46° = 7.91 units.
Therefore, the perimeter of ΔABC is :
P = 11 + 7.64 + 7.91 units
P = 26.55 units
Hence, this is the required solution.

volume of cylinder with a base radius of 5 and height of 3
Answer:
235.5.
Step-by-step explanation:
VOLUME: THE AMOUNT OF SPACE OCCUPIED BY A 3D OBJECT.
The formula for volume of a cylinder is:
[tex]pi*r^2*h (3.14 * radius *radius * height)[/tex]
The radius of this cylinder is 5 and the height is 3.
Now, we can plug the numbers in the formula.
SOLVE:
[tex]pi *5^2*3(3.14*5*5*3)=235.5.[/tex]
The product of the equation is 235.5.
I, therefore, believe the volume of this cylinder is 235.5.
