Step-by-step explanation:
A bill originally amounting Rs 1550, now amounts to Rs 1736 after adding VAT. Find the VAT rate.kaabil original amounting
Answer: 12%
Step-by-step explanation:
Original amount = Rs 1550
VAT = Rs 1736 - Rs 1550 = Rs 186
VAT rate = VAT/Original amount × 100
= 186/1550 × 100
= 18600/1550
= 12%
Therefore, the VAT rate is 12%.
Check:
= Rs 1550 + (12% × Rs 1550)
= Rs 1550 + $186
= Rs 1736

Answer:
interest: 945, FV: 6345
FV= 323711.4, Interest: 226211.4
25.21 years
Step-by-step explanation:
question 1:
simple interest formula
PV(1+it)
30 months is equal to 30/12 years or 2.5 (so t= 2.5)
5400(1+.07*2.5)= 6345
This is the future value, to find the interst subtract the present value
6345-5400= 945
2.)
future value of continously compounding interst:
PV(e^(it))
97500*e^(.06*20)= 323711.4

Answer:
43.82 mph
266.67 feet
Step-by-step explanation:
Given :
S = √30fl
S = speed of car
f = drag Coefficient
l = Length of skid mark
If f = 0.8 ; l = 80 feets
s = √30fl
s = √(30*0.8*80)
s = √1920
s = 43.817
s = 43.82 mph
B.)
s = 80 mph
f = 0.8
s = √30fl
80 = √30*0.8*l
80 = √24l
Square both sides
80² = 24l
6400 = 24l
l = 6400/24
l = 266.67 feets
Twice a number added to another number is –8. The difference of the two numbers is 2. Find
the numbers
Answer:
-2 and -4
Step-by-step explanation:
→ Make variable's for each number
x is the first variable and y is the second
→ Form equations
2x + y = -8
x - y = 2
→ Solve
3x = -6
→ Divide both sides by 3
x = -2
→ Resubstitute that into one of the equations
-2 - y = 2
→ Add 2 on both sides
-y = 4 therefore y = -4

1. Cheryl Douglas works 43 hours in a week for an exempt salary of $1,827 per week. What are Cheryl's gross weekly earnings?
Answer:
$1827
Step-by-step explanation:
Since Cheryl is said to be paid an exempt salary. Then it can be said that Cheyk does not qualify for minimum wage or overtime pay, Hence, exempt payment is in terms or salary rather than wage. Similarly. Gross earning refers the amount a worker receives as income over a certain period of time. The gross income has not been subjected to tax charges or any form of deduction. Hence, it could be said to be the outright earning paid to an employee before any deduction is made.
Hence, Cheryl's gross weekly earning is $1827 per week.

Step-by-step explanation:
10x-3(x-6)=x+30
Distribute
10x -3x+18 = x+30
Combine like terms
7x +18 = x+30
Subtract x from each side
7x-x +18 = x+30-x
6x +18 = 30
Subtract 18
6x+18-18 = 30-18

What are the zeros of P(m) = (m2 – 4)(m2 + 1)?
Answer:
m=4, -1
Step-by-step explanation:
if i am interpreting this correctly, you are wanting to find at what value of m would the solution be zero.
so, there are two expressions that can cause an answer of 0.
1) if 0=m2-4
so solve for m2, and you get 4=m2
2) if 0=m2+1
solve for m2, and you get -1=m2
you can check your work by plugging the values back into the equation.
P(m)=(4-4)(4+1)
=(0)(5)
=0
and
P(m)=(-1-4)(-1+1)
=(5)(0)
=0

I need help with this question. I have a few correct and need help with the ones that are not.
Step-by-step explanation:
For the first one, you have the -2 step right, but now we're at
f(x) -2 = x³
We have to take the cube root of each side to solve for x, which looks like
∛(f(x)-2) = x or (f(x)-2)^(1/3) = x. This makes our inverse function ∛(x-2) Putting a 3 to the side multiplies the value by 3, and doesn't cube root it.
For your next incorrect answer, you simply need to plug the inverse function that I just gave in.
For the one after that, the question is asking to plug in f(x). We know that our inverse is ∛(x-2) , and the question is asking to plug f(x) in for x here. Thus, in the box, simply put down x³+2
For the last incorrect answer, we need to find the cube root of something, and by plugging in f(x) into the previous one, we are left with ∛(x³+2-2). Therefore, in the box, simply put down x³ as that is what's left
Find the Surface Area and the Volume.
Answer:
volume = 1,000
surface area = 930
Step-by-step explanation:
the volume = (½×(14+6) ×4) × 25

the surface area =
(2×½×(14+6) ×4) + ((14+7+7+6) ×25)

Question 4-6. Earth is 93 million miles from the Sun. Pluto is 4.67 billion miles from the Earth.Calculate the ratio of the distance from Pluto to Earth to the distance from Earth to the Sun. Use scientific notation to calculate the ratio and express your answer in standard notation. (round to the hundredths place)
Answer:
PE/SE = 5.02×10¹
Step-by-step explanation:
Sun-Earth (SE) = 93×10⁶ miles
Pluto-Earth (PE) = 4.67×10⁹ miles
so, PE/SE = (4.67×10⁹) / (93×10⁶) = (4.67×10³)/93 =
= 50.215053763440860215... =
= 5.02×10¹ / 1 or simply 5.02×10¹
in other words, Pluto is a little bit more than 50 times farther away from Earth, than Earth is from the Sun.
The filling variance for boxes of cereal is designed to be .02 or less. A sample of 41 boxes of cereal shows a sample standard deviation of 0.16 ounces.

b. State the null and alternative hypotheses.
c. Calculate the value of the test statistic (to 2 decimals).
d. The p-value is:_______
e. What is your conclusion?
Answer:
-
Null hypothesis H₀ : σ² ≤ 0.02
Alternative hypothesis Hₐ : σ² > 0.02
- Chi Square = 51.2
- p-value = 0.1104
- since the calculated p-value ( 0.1104 ) is greater than the level of significance ( 0.05 ).
We fail to reject null hypothesis.
- So at, 5% level of significance, there is no evidence to support that the variance in the cereal box fillings is designed to be 0.02 or less.
Step-by-step explanation:
Given the data in the question;
filling variance for boxes of cereal is designed to be .02 or less
sample size n = 41 boxes
standard deviation S = 0.16 ounces
level of significance = 0.05
Hypothesis;
Null hypothesis H₀ : σ² ≤ 0.02
Alternative hypothesis Hₐ : σ² > 0.02
{ Upper tail test }
Test statistics;
Chi Square = [ ( n-1 ) × S² ] / σ²
Chi Square = [ ( 41-1 ) × (0.16)² ] / 0.02
Chi Square = [ 40 × 0.0256 ] / 0.02
Chi Square = 1.024/ 0.02
Chi Square = 51.2
Degree of freedom df = n - 1 = 41 - 1 = 40
Chi square value at 0.05 and df of 40 = 55.7585
p-value = 0.1104
since the calculated p-value ( 0.1104 ) is greater than the level of significance ( 0.05 ).
We fail to reject null hypothesis.
So at, 5% level of significance, there is no evidence to support that the variance in the cereal box fillings is designed to be 0.02 or less.
A positive real number is 5 more than another. When - 10 times the smaller is added to the square of the larger, the result is 57. Find the numbers.
Answer:
4√2 and 5+4√2
Step-by-step explanation:
Let the two numbers be x ad y
Smaller = y
Bigger = x
If a positive real number is 5 more than another, then;
x = 5 + y ... 1
When - 10 times the smaller is added to the square of the larger, the result is 57, then;
-10y + x² = 57 ...2
Substitute 1 into 2;
-10y + (5+y)² = 57
-10y + 25+10y+y² = 57
y²+25 = 57
y² = 57 - 25
y² = 32
y = √32
y = 4√2
Since x = 5 + y
x = 5 + 4√2
Hence rhe numbers are 4√2 and 5+4√2

1. Round 0.007492 to the nearest hundredth.
Answer:
The answer is 0.01
Step-by-step explanation:
so in order to round it you have to know after the decimal it goes: tenths, hundreds, thousands (0 tenths, 0 hundreds, 0 thousands)
So 0.007492, take the first 3 numbers after the decimal, 0.007, since it will be in the hundreds place, lets see if we can round the 0 up. If the number behind 0 is greater then or equal to 5 round up, if the number is less then 5 then it stays the same. Since 7>5 it rounds up, so the 0 becomes 1. So your new number will be 0.01
Hoped this helped :D
By rounding 0.007492 to the nearest hundredth, we get 0.01.
What is the method of rounding a number?The number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Measure of opposite side (KL) = 7.4
Measure of adjacent side (ML) = 14
By applying tangent rule in the given triangle,
tan(∠LMK) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
