Step-by-step explanation:
C.P=5×1=Rs.5
S.P.=4×1=Rs.4
Loss=C.P.=S.P.
=Rs.5-Rs.4
=Re.1
loss%=loss/C.P ×100
=1/5×100%
=20%
Find the length of the third side. If necessary, round to the nearest tenth.
20
25
Answer:
15
Step-by-step explanation:
hypotenuse (h) = 25
perpendicular (p) = 20
base (b) = ?
we know by using Pythagoras theorem we get
b = √h² - p²
= √25² - 20²
= √225
= 15

solve please :) need to figure out which one is true
Answer:
Option B is true
Step-by-step explanation:
The formula for Cos is Adjacent/hypotenuse. 12 is Adjacent to angle e, and 17 is the hypotenuse.
Answer:
B: cos e = 12/17
Step-by-step explanation:
When using the SOHCAHTOA method you can see that Cos is adjacent over hypotenuse and in the triangle diagram they give you the measurements of the hypotenuse and the adjacent only, so you know that they would be using the cos equation.
A chord consists of notes that sound good together. The C major chord starting at middle C has the following frequencies: C - 262 Hz E - 330 Hz G - 392 Hz determine the ratio of the frequency of E to C. Express the answer in a simple integer ratio. How many E waves will fit in the length of four C waves. a. 2 b. 3
Answer:
The frequency of note E is:
f(E) = 330 Hz
The frequency of note C is:
f(C) = 262 Hz
The ratio of the frequency of note E to the frequency of note C is just the quotient of these two frequencies:
r = f(E)/f(C) = 330Hz/262Hz = 330/262 = 1.26
Now, we want to find how man E waves will fit in the length of four C waves.
Note that here the word "length" is used, so we need to work with the wavelengths, not with the frequencies.
For waves, we have the relationship:
v = f*λ
where:
v = velocity (in this case, velocity of the sound = 343 m/s)
f = frequency
λ = wavelength.
So, the length of a single E wave is:
λ(E) = (343 m/s)/(330 1/s) = 1.04 m
And the length of a single C note is:
λ(C) = (343 m/s)/(262 1/s) = 1.30 m
In four C waves, the length is:
4*λ(C) = 4*1.30m = 5.2m
The number of E waves that fit in the length of four C waves is equal to the quotient between the length of four C waves and one E wave:
N = (4*λ(C))/(λ(E) ) = (5.2 m)/(1.04m) = 5.14
So we can fit 5 E waves into four C waves.
Answer:
The ratio of the frequency of E to C can be found by dividing the frequency of E by the frequency of C:
330 Hz / 262 Hz ≈ 1.26
To express the answer in a simple integer ratio, we can divide both 330 Hz and 262 Hz by their greatest common factor, which is 2:
330 Hz / 2 = 165 Hz
262 Hz / 2 = 131 Hz
So the ratio of the frequency of E to C is:
165 Hz / 131 Hz = 15/12 ≈ 1.25
This ratio is approximately equal to 5/4
Therefore, the answer is (A) 5 to 4

B
-0.59 and -3.41
са
3.41 and 0.59
D

B
Step-by-step explanation:
x^2 + 4x + 2 = 0; a=1, b=4, c=2
D= b^2 - 4ac = 16 - 8 = 8>0
-> x1/2= (-b +/- √D)÷2×a= (-4 +/- √8)÷2= 2(-2 +/- √2)÷2

Find the exact solution to the equation. 5^(6-2x) = 25
Answer:
x = 2
Step-by-step explanation:
Note that 25 = 5² , then
[tex]5^{(6-2x)}[/tex] = 5²
Since the bases on both sides are 5 then equate the exponents
6 - 2x = 2 ( subtract 6 from both sides )
- 2x = - 4 ( divide both sides by - 2 )
x = 2

Find the circumference of a circle.
Answer:
56.52
Step-by-step explanation:
1. multiply your r by 2
so 9*2= 18
2. multiply that by pi, which you substitute 3.14 in for
so 18*3.14=56.52
Radius ( r ) = 9 inches
[tex] \blue{To \: find\:-}[/tex]Circumference of the Circle ?
[tex] \blue{Solution\:-}[/tex]Circumference of the Circle = 2πr
Putting the value of r in the formula -
[tex] = 2\pi r[/tex]
[tex] = 2 \times \frac{22}{7} \times 9[/tex]
[tex] = 56.5 \: inches[/tex]
[tex] \mathsf \pink {Hence, \: the \: circumference \: of \: the \: circle \: is \: 56.5 \: in.}[/tex]
Your friend has n pennies. You have 29 pennies. You and your friend have a total of 40 pennies. Which equation could be used to find n?
Answer:
40-29=n
Step-by-step explanation:
You have 29 in total yall have 40
so to find ur friends we subtract
Answer:
Step-by-step explanation:
your pennies + your friends pennies = the total number of pennies between you two
so the equation would be :
29 + n = 40
(im not sure if you wanted it solved for n but here is the solution just in case)
29 + n = 40
n = 40 - 29
n = 11

Answer:
Quarter pounder has -580 calories and the Whooper has
1589 calories
Step-by-step explanation:
Let x represent quarter pounders and y represent the Whoppers.
2 QP and 3 Whoppers provide 3607 calories and one of each provide 1009. so let set up the system
[tex]2x + 3y = 3607[/tex]
[tex]x + y = 1009[/tex]
Apply subsitution method
[tex]y = 1009 - x[/tex]
[tex]2x + 3(1009 - x) = 3607[/tex]
[tex]2x + 3027 - 3x = 3607[/tex]
[tex] - x + 3027 = 3607[/tex]
[tex] - x = 580[/tex]
[tex]x = - 580[/tex]
Plug the system back into one of the equations and we get
[tex]y = 1589[/tex]

a sequence U1, U2,U3...... is defined by the relation Un +1 = 2Un +5. if U1 =2, find U1
Correct question:
a sequence U1, U2,U3...... is defined by the relation [tex]U_{n +1} = 2U_n +5[/tex]. if U1 =2, find U2 and U3
Answer:
U2 = 9
U3 = 23
Step-by-step explanation:
Given sequence;
[tex]U_{n +1} = 2U_n +5[/tex]
U1 = 2
U2 = ?
[tex]U_{n +1} = 2U_n +5\\\\U_2 = 2(U_1) + 5\\\\U_2 = 2(2) + 5\\\\U_2 = 4 + 5\\\\U_2 = 9[/tex]
Solving for U3;
[tex]U_3 = 2(U_2) + 5\\\\U_3 = 2(9) + 5\\\\U_3 = 18 + 5\\\\U_3 = 23[/tex]
