What is Trigonometry?

Trigonometry is a field of mathematics that explores the connections between triangle side lengths and angles.

Solution:

In the triangle ABC,

The perpendicular = BC

The Base = AB = 6 miles

by using the trigonometric ratio "tan"

tan (58) = BC / AB

8.33 = BC / 6

49.98 miles = BC

BC = 50 miles (approx)

Step-by-step explanation:

Answer:9/7

Step-by-step explanation:

a) An algebraic expression for the gasoline left in the fuel tank is L = 0.4w.

b) If w = 15.5, the amount of gasoline left in the tank at the end of the journey was 6.2 gallons.

An algebraic expression is a mathematical statement that combines constants and variables together with mathematical operands.

The mathematical operands include addition, subtraction, division, multiplication, etc.

Let L = the amount of gasoline left

Let the full capacity of the fuel tank = w gallons

Gasoline consumed on the journey = 60% = 0.6

L = w - 0.6w

L = 0.4w

If w = 15.5

L = 0.4(15.5)

= 6.2 gallons

Answer:

  no change

Step-by-step explanation:

Given a temperature rise of 3.85 °F over 4 hours after noon, when the temperature is 85.4 °F, you want to know the change between 4 pm and 5 pm if the temperature at 5 pm is 89.25 °F.

The temperature at 4 pm is the sum of the noon temperature and the change in the 4 hours after noon:

  85.4 °F + 3.85 °F = 89.25 °F

The change from 4 pm to 5 pm is the difference between the 5 pm temperature and the 4 pm temperature:

  82.25 °F -89.25 °F = 0 °F

There is no change in the temperature between 4 pm and 5 pm.

Answer:

a: 0.3125kg

b: 4

Step-by-step explanation:

for a we simply calculate 5 * 0.5 ^ 4.
we then see that the weight after 4 minutes is smaller than 0.5kg, but if we go back to 3 minutes (by multiplying our solution to a by 2), giving us 0.625kg, which is now bigger than 0.5kg. meaning 4 minutes is the first whole amount that will give us a weight smaller than 0.5kg.

Step-by-step explanation:

The hire purchase price of a refrigerator is $6509.A deposit of $500 is made and the reminder is paid in equal monthly payments of $250. Calculate the number of monthly payments that must be made.

amount paid over x months:  

$6509 - $500 = $6,009

Equal payments of $250:

$6,009 / $250 = 24.036 months of payments

[Depending on if they want the answer rounded up, answer may become 25]

Answer:

hire purchase= $6509

deposit=$500

monthly payment=$250

no of monthly payment that must be made=hire purchase - deposit divided by monthly payment

$6509-$500/$250=$6009/$250= 24.036 month

The volume of the cylinder in cubie centimeter is 628 [tex]cm^{3}[/tex]

How to find the volume of cylinder?

1. Find the radius of the circular base: Since both circles are the same size, either one will work. Move on if you are aware of the radius. If you don't know the radius, you can divide the diameter of the circle by 2.

2. Find the height of the cylinder : Continue if you already know the height. Otherwise, measure it with a ruler. The height is determined by the separation of the two bases' edges.

diameter (d) = 20

radius = [tex]\frac{20}{2}[/tex]

What is an exponent?

Exponent is the process of expressing large numbers in terms of powers. In other words, the exponent describes how many times a number has been multiplied by itself.

According to the zero exponent rule, any base with a zero exponent is equal to one. For instance, [tex]x^{0} = 1[/tex].

We have,

[tex]= \frac{1.25\\ * \\ 10^{-3}}{1.25 \\ * \\ 10^{-3}}[/tex]

[tex]= \frac{1.25\\ * \\ 10^{-3}}{1.25 \\} * 10^{3}[/tex]

Using the multiplication rule of fraction [tex]a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}[/tex]

[tex]= \frac{1.25 \ * \ 10^{-3} \ * \ 10^{3}}{1.25 \\}[/tex]

= [tex]= 10^{-3} * 10^{3}[/tex]

By applying the exponent rule [tex]\:a^b\cdot \:a^c=a^{b+c}[/tex] we get,

Add or subtract the numbers = 3 + 3 = 0

[tex]= 10^{0}[/tex]

20 x 4 = 80

Answer:

x = 20 degrees ; y = 70 degrees

Step-by-step explanation:

angle supplementary to 40 = 180 - 40 = 140 degrees

in isosceles triangle has the angles of the base with the same measure

140 + (2x) = 180

2x = 180 - 140

2x = 40

2/2 x = 40/2

x = 20 degrees

90 - 20 = 70 degrees

70 + y + 40 = 180

110 + y = 180

y = 180 - 110

y = 70 degrees

Answer:

Step-by-step explanation:

An amount of $ 92,495.60 must be the initial deposit to become into $ 300,000 by compound interest.

In this problem we must determine the initial deposit that must become into $ 300,000 by compound interest after a period of 30 years. Compound interest model is a model where money gains interest continuously, whose formula is:

C' = C · (1 + r / 100)ⁿ

Where:

If we know that C' = 300,000, r = 4 and n = 30, then the initial deposit is:

C = C' / (1 + r / 100)ⁿ

C = 300,000 / (1 + 4 / 100)³⁰

C = 92,495.60

Answer: 26/24

Step-by-step explanation:

First we have to convert 5/6 with a denominator of 24 so 6 times what makes 24, that is 4 & whatever you do with the denominator, you have to do it with the numerator. So 5 times 4 is 20, the new fraction is 20/24. Now, we need to find what we need to add with 20/24 to get 41/24, so we subtract 20/24 from 41/24 & that is 21/24. We can check if it's correct by adding both 21/24 and 20/24 & that makes 41/24.

A line segment that bisects another line segment at a 90° angle is known as a perpendicular bisector.

A line segment that bisects another line segment at a 90° angle is known as a perpendicular bisector. In other terms, a perpendicular bisector separates a line segment into two equal halves by intersecting it at a 90° angle.

Given coordinates of the endpoints of a line segment  (-9, 3) and (-3,-1).

What is a Quadratic equation ?

A second-degree equation of the form ax² + bx + c = 0 is known as a quadratic equation in mathematics. Here, x is the variable, c is the constant term, and a and b are the coefficients. Since x is a second-degree variable, this quadratic equation has two roots, or solutions.

The given expression is,

x = x² - 20

We have to make the equation in quadratic form i.e, ax² + bx + c = 0

so, first take x to the right side

0 = x² - 20 - x

Now swap the equation,

x² - 20 - x = 0

put 'x' term in middle and constant term at last like this,

x² - x - 20 = 0
