Math can help you if you ever wanna build a desk in the future;)
Maths can be used in the day-to-day shopping at home groceries and vegetables etc.
What is maths?Numbers, formulae, and related structures, shapes, and the spaces in which they are contained, as well as quantities and their variations, are all covered in the field of mathematics.
An example of daily life is if you are going to the market to purchase fruits the cost of 1 kg of apple is 200rs but you want to buy 30 rs apple only. Then the amount in kg for the 30rs apple will be calculated by using maths.
200rs apple = 1 kg
1 rs apple = 1 / 200 kg
30 rs apple = ( 1 x 30 ) / 200
30 rs apple = 0.15 kg or 150 grams
In this way, you will get the exact amount of apple for 30 rupees amount by using mathematics
Therefore, maths can be used in the day-to-day shopping at home groceries and vegetables, etc.

If a wave has a wavelength of 20 meters and is
traveling at a rate of 60m/s, what is its
frequency?
Answer:
Frequency of wave = 3 Hertz
Step-by-step explanation:
Given that:
Wavelength of wave = 20 meters
Velocity of wave = 60m/s
We know that:
v = fλ
Here,
v = velocity , f = frequency and λ = wavelength
Putting values in formula
60 = f(20)
20f = 60
Dividing both sides by 20
[tex]\frac{20f}{20}=\frac{60}{20}[/tex]
f = 3 Hertz
Hence,
Frequency of wave = 3 Hertz

The base of an isosceles triangle is seven less than twice one of the congruent sides. If the perimeter of the triangle is 63 cm, find the length of each side.
Answer:
17.5
Step-by-step explanation:
let 'x' = each congruent side
let '2x - 7' = side of base
x + 2x - 7 = 63
3x = 70
x = 17.5
Write two multiplication equations that compare the number of blue fish 16 to the number of yellow fish 4
Answer:
b = 4y
y = 1/4 * b
Step-by-step explanation:
Number of Blue fish = 16
Number of yellow fish = 4
Let:
Blue fish = b
Yellow fish = y
b = 4y
b = 4(4)
b = 16
From ;
b =4y
y = b/4
y = 1/4 * b
Hence,
y = 1/4 * 16
y = 16/4
y = 4

TODAY ONLY: Towels are 30% off at the Towel Emporium. If our total before discount was $99.30, what is the price we will pay?
Answer:
$69.51
Step-by-step explanation:
To solve the discount problem we have to multiply the price by the new percent (trust me it will make sense later)
To find the new percent after the 30% discount we have to subtract 30% from 100% which will leave us with 70% or 0.70
Now we multiply:
$99.30 x 0.70 = 69.51
So the new price after the discount is $69.51

Answer: b the second answer
Step-by-step explanation:
2. Write the slope-intercept form of the equation of the line described.
Parallel to y=-x-5; through (4, -3)
Answer:
y = -x + 1
Step-by-step explanation:
We're putting it into the form y=mx+b where m is the slope, and b is the y-intercept.
When two lines are parallel, they have the same slope, so the slope is going to be -1.
New equation: y = -x + b.
Now, you know that (4, -3) is a solution so you can plug in x = 4 and y = -3, then see what value of b make the equation true.
-3 = -4 + b
add 4 to both sides
1 = b
This means that the equation is y = -x + 1

An angle measures 58.6° less than the measure of its complementary angle. What is the
measure of each angle?
Answer:
Your answer is 31.4°.
Step-by-step explanation:
The answer itself just requires very simple thinking. Complementary angles are any two angles that add up to 90 degrees. We are given ANGLE<1, so all we have to do is subtract 90 from 58.6 to find ANGLE<2.
90°-58.6°= 31.4°

a || b . Find the value of the star.
Record your answer as a decimal. Round to the nearest hundredth if necessary.
Answer:
The star equals 96
Step-by-step explanation:
The star will be equal to 5x-14 because they are vertically opposite.
The two exterior angles are supplementary. Set up the equation
5x - 14 + 3x + 18 = 180 Combine the terms on the left.
8x + 4 = 180 Subtract 4 from both sides
8x = 180 - 4 Combine
8x = 176 Divide by 8
x = 176 / 8
x = 22
===================
5x - 14
5*22 - 14
