Formula:- I = PRT/100
Where,
I is interestP is principleR is rateT is time⇒ I = 500×5×3/100
⇒ I = 7500/100

what is an area of a trapezoid
Answer:
144
Step-by-step explanation:
Required area= Area of rectangle +2×(Area of Triangle)
=(10×8)+2×(1/2×8×8)
=80+64=144 in²
Answer:
144 in²
Step-by-step explanation:
To solve for the area of a trapezoid divided into a parallelogram (in this case a rectangle) and two triangles, you calculate the area of each part and add it together.
the area of a triangle = (base • height) / 2
the area of a parallelogram = (base • height)
so:
1. Calculate area of first triangle. 8 • 8 = 64, 64/2 is 32
2. Calculate the area of the second triangle. Since in this situation you have two equal triangles, you multiply the answer to the first part by 2 and get 64 in² again.
3. Calculate the area of the rectangle. 8 • 10 = 80 in²
4. Add the two numbers together. 80 + 64 = 144 in²
Savannah's favorite candles are so popular that the price has been
increased. The price for a 24 oz. candle used to be $20, but now it is $28.
By what percentage has the price been marked up? *
Answer
70%
85%
48%
40%
Answer:
40%
Step-by-step explanation:
The increase was $8. Divide the increase by the original amount.
8/20 = .4
The decimal answer 0.4 converts to a percent answer of 40%. (.4×100=40)
The candle was marked up 40%.

Instead of pricing, the food outlets can improve the physical and quality aspects of their chicken brands, increase consumer advertising, trade promotions, product differentiation, and locate their outlets in niche markets.
Thus, physical and quality improvements, outlet location and trade promotions, differentiation, and advertising can become non-price competition strategies for these food outlets.

A turtle lives in a garden and a hedgehog lives in the woods. They leave their homes at the same time walk toward each other and meet in 5 hours. The turtle walks 10 meters per hour slower than the hedgehog. If the turtle had left home 4 1/2 hours earlier than the hedgehog had left his home, the two would meet 150m from the woods. Find the distance between the garden and the woods. PLEASE EXPLAIN WHY.
Based on the calculations, the distance between the garden and the woods is equal to 383 meters.
How to calculate the distance.
First of all, we would assign a variable to the different speeds of the turtle and hedgehog as follows:
Let the turtle's speed be S₁.Let the hedgehog's speed be S₂.Mathematically, distance is given by this formula:
Distance = speed × time
Translating the word problem into an algebraic expression, we have;
If they both meet in 5 hours:
D = (S₁ + S₂) × 5
D = 5S₁ + 5S₂ ......equation 1.
Turtle's speed is 10 meters per hour slower than the hedgehog:
S₁ = S₂ - 10 .....equation 2.
If the turtle had left home 4.5 hours earlier than the hedgehog had left his home:
9.5S₁ + 5S₂ = D + 150 .....equation 3.
Substituting enq. 2 into eqn. 1, we have:
D = 5(S₂ - 10) + 5S₂
D = 5S₂ - 50 + 5S₂
D = 10S₂ - 50 .....equation 4.
Equating eqn. 3 and eqn. 4, we have:
10S₂ - 50 = 9.5(S₂ - 10) + 5S₂ - 150
10S₂ - 50 = 9.5S₂ - 95 + 5S₂ - 150
10S₂ - 50 = 14.5S₂ - 245
14.5S₂ - 10S₂ = 245 - 50
4.5S₂ = 195
S₂ = 195/4.5
S₂ = 43.3 m/h.
Now, we can find the distnace:
D = 10S₂ - 50
D = 10(43.3) - 50
D = 433 - 50
D = 383 meters.

The profit to the company will be maximum that means pear company should produce 11000 phones for the maximum profit.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
Function representing the cost to the manufacturer is,
C(x) = -20x²+ 48000x + 19351
A function that represents the revenue generated is,
R(x) = -23x² + 114000x
Function representing profit to the company,
Profit = Revenue generated - Cost price
= -23x² + 114000x - ( -20x²+ 48000x + 19351)
= -23x² + 20x² + 114000x - 48000x - 19351
P(x) = -3x² + 66000x - 19351
Since this function is a quadratic function, the maximum price generated would be x = -b/2a
From the given quadratic function, a = (-3), b = 66000 and c = -19351
x = - 66000/ 2(-3)
x = -66000/-6
x = 11000
x = 11000 the profit to the company will be maximum.
That means pear company should produce 11000 phones for the maximum profit.

A) 54, 66, 78
B)
55, 68,81
C) 1,2,3
D) 55,70,83
Answer:
B) 55, 68,81
Step-by-step explanation:
42-29=13
29-16= 13
So 42 + 13= 55
55+ 13= 68
68+ 13= 81
Answer:
B) 55, 68, 81
Step-by-step explanation:
Given sequence: 3, 16, 29, 42
To determine if the sequence is arithmetic or geometric, work out the difference in the terms.
[tex]\sf 3 \underset{+13}{\longrightarrow} 16 \underset{+13}{\longrightarrow} 29 \underset{+13}{\longrightarrow} 42[/tex]
This sequence adds 13 each time, so as the common difference is constant, it is an arithmetic sequence. To find the next term in the sequence, simply add 13 to the last term:
42 + 13 = 55
55 + 13 = 68
68 + 13 = 81
Therefore, the next three terms in the given sequence are 55, 68, 81
To solve this using the general form of an arithmetic sequence:
[tex]a_n=a+(n-1)d[/tex]
where:
[tex]a_n[/tex] is the nth terma is the first termd is the common difference between termsGiven:
a = 3d = 13[tex]\begin{aligned}\implies a_n & =3+(n-1)13\\ & = 3+13n-13\\ & = 13n-10\end{aligned}[/tex]
Therefore, the next 3 terms in the sequence are:
[tex]\implies a_5=13(5)-10=55[/tex]
[tex]\implies a_6=13(6)-10=68[/tex]
[tex]\implies a_7=13(7)-10=81[/tex]

Farmer Brown had 25 cows and chickens. They had a total of 72 legs. How many cows and how many chickens did Farmer Brown have?
Solution:Let the number of cows be "x" and the number of chickens be "y".
According to question,
x + y = 25 4x + 2y = 72 -->(ii)
=> 4(x + y) = 25 × 4
=> 4x + 4y = 100 -->(i)
By Elimination method,
Equation (i) - (ii)
(4x + 4y) - (4x + 2y) = 100 - 72
=> 4x + 4y - 4x - 2y = 28
=> 2y = 28
=> y = 28/2
=> y = 14
Putting the value of "y" in Equation (ii)
4x + 2y = 72
=> 4x + 2 × 14 = 72
=> 4x + 28 = 72
=> 4x = 72 - 28
=> 4x = 44
=> x = 44/4
=> x = 11
Therefore,Total number of cows = 11
Total number of chickens = 14
Note: In the second equation of this question I've taken 4 and 2.
The reason behind it is simple. Since, I've assumed the number of cows is "x" and a cow has four legs that why infront of "x" I've put 4.
And a chicken has 2 legs and I've assumed it as "y" therefore infront of "y" I've put 2.
======================================
Question no.10:Farmer Brown had 28 cows and chickens. They had a total of 96 legs. How many cows and how many chickens did Farmer Brown have?
Solution:Let the number of cows be "x" and the number of chickens be "y".
According to question,
x + y = 28 4x + 2y = 96 -->(ii)
=> 4(x + y) = 28 × 4
=> 4x + 4y = 112 -->(i)
By Elimination method,
Equation (i) - (ii)
(4x + 4y) - (4x + 2y) = 112 - 96
=> 4x + 4y - 4x - 2y = 16
=> 2y = 16
=> y = 16/2
=> y = 8
Putting the value of "y" in Equation (ii)
4x + 2y = 96
=> 4x + 2 × 8 = 96
=> 4x + 16 = 96
=> 4x = 96 - 16
=> 4x = 80
=> x = 80/4
=> x = 20
Therefore,Total number of cows = 20
Total number of chickens = 8
Note: In the second equation of this question I've taken 4 and 2.
The reason behind it is simple. Since, I've assumed the number of cows is "x" and a cow has four legs that why infront of "x" I've put 4.
And a chicken has 2 legs and I've assumed it as "y" therefore infront of "y" I've put 2.

mean? Assume the population standard deviation is 38 minutes. Round your final answer up to the next whole number.
Using the z-distribution, as we have the population standard deviation, it is found that a sample of 96 people must be taken.
What is the margin of error for the z-distribution?It is given by:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which:
z is the critical value.[tex]\sigma[/tex] is te population standard deviation.n is the sample size.In this problem, we have a 99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.
Additionally, we have that [tex]\sigma = 38, M = 10[/tex], hence we solve for n to find the minimum sample size needed.
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]10 = 2.575\frac{38}{\sqrt{n}}[/tex]
[tex]10\sqrt{n} = 38 \times 2.575[/tex]
[tex]\sqrt{n} = 3.8 \times 2.575[/tex]
[tex](\sqrt{n})^2 = (3.8 \times 2.575)^2[/tex]
