Answer:

4degrees

Step-by-step explanation:

Given the following

Height of the airplane = 37000feet

distance covered on landing = 100miles = 100(5280)

distance covered on landing  = 528,000feet

Using the SOH CAH TOA

sin theta = opposite/hyp

sin theta = 37000/528000

sin theta = 37/528

theta = arcsin (37/528)

theta = 4 degrees

Hence average angle at which the airplane must descend for landing is 4degrees

Answer:

(C) Sophie used the wrong height for the pyramid.

Step-by-step explanation:

she should have subtracted 4 from 30 because that was apart of the prism

The total volume is 7448  cubic millimeters. Sophie has made mistake in copying height of pyramid.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, a rectangular prism with a length of 28 millimeters, width of 21 millimeters, and height of 4 millimeters.

Volume of rectangular prism = Length×Width×Height

= 28×21×4

= 2352 cubic millimeters

A rectangular pyramid with a base of 28 millimeters by 21 millimeters and height of 26 millimeters.

Volume of a rectangular pyramid = (lwh)/3

= (28×21×26)/3

= 15288/3

= 5096 cubic millimeters

Total volume = 2352+5096

= 7448  cubic millimeters

Hence, Sophie has made mistake in copying height of pyramid.

Answer: 782.05 miles.

Step-by-step explanation: Percentage is a ratio expressed as fraction of 100, in other words, 61% is represented as [tex]\frac{61}{100}[/tex] or 0.61.

London slept 61% of the journey, so it means he was awake for 39% of the journey. Now the total trip is [tex]\frac{100}{100}[/tex] or 1, so the relationship will be

0.39 ---- 305 miles

   1   ----- x

[tex]x=\frac{305}{0.39}[/tex]

x = 782.05

The total length of the trip was 782.05 miles.

Answer:

14.90 to 16.70 tons

Step-by-step explanation:

We are given;

Sample size; n = 49

Mean; x¯ = 15.8

Sample standard deviation; s = 3.85

At 90% Confidence interval, z = 1.645

Formula for confidence interval is;

CI = x¯ ± z(s/√n)

Thus;

CI = 15.8 ± 1.645(3.85/√49)

CI = 15.8 ± 0.90

CI = 14.90 to 16.70 tons

Answer:

4448.23

Step-by-step explanation:

[tex]AV=PV(1+\frac{i}{n})^{nt}\\\\6000=PV(1+\frac{.06}{12})^{5*12}\\\\6000=PV*1.3488\\\\PV= 4448.23[/tex]

The present value of an investment that will be worth $6000 at the end of five years is, $4448.23

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Annual value = $6,000

Time = 5 years

Rate = 6%

Hence, We get;

A = P (1 + r/n)ⁿˣ

Substitute all the values, we get;

⇒ 6000 = P (1 + 0.6/12)⁶⁰

⇒ 6000 = P × 1.3488

⇒ P = $4448.23

Thus, The present value of an investment that will be worth $6000 at the end of five years is, $4448.23

y = 6x

Step-by-step explanation:

You can easily find the slope by using slope formula:

(y2-y1) / (x2-x1) (the numbers are subscript)

E.g: (24-12) / (4-2) = 12/2 = 6

m(slope) = 6

Answer: D , p = n (800 - 450) - 3000

Step-by-step explanation: Firstly, you have to account for how much money Rafael is making off of each computer (800 - 450). That factor is then multiplied by the variable "n" which represents the amount of computers sold. Lastly, since this is an equation to calculate his monthly profits, you have to subtract the rent that he is paying ($3000) from the total profit that he made off of selling the computers. Therefore, giving you the equation

P (profit) = n (amount of computers sold) (800-450) - 3000 (rent).

The equation that represents Rafael's monthly profit selling 'n' numbers of computers is D. P = n(800 - 450) - 3000.

An equation represents equality for the terms that are on the both side of the equal sign.

Given Rafael buys computers for 450 dollars and sells them for 800 dollars each.

He also had to pay 3000 dollars for rent and utilities for the store and the number of computers sold in each month is given by 'n'.

∴ The equation that represents his profit(P) in a month is,

P = n(800 - 450) - 3000.

Answer:

Step-by-step explanation:

An equation is like a sentence, just using a different language. Mathematical equations are telling you to do something, giving you information on how to respond, or come up with an answer. It's up to you to learn this language. However, once you know it, you can write in this language! You, too, can write algebraic equations.

Parts of a Mathematical Equation

A mathematical equation, also known as a statement, shows that two separate expressions are equal. The two expressions are usually connected by the "equal-to" (=) sign. You can find the expressions in a mathematical statement by looking at the left-hand side and the right-hand side of the equation, using the = sign as the point of reference.

Example: 2x + 3 = 11

It can be helpful to view equations as a scale in which weights are used to keep it balanced. The scale is balanced when what is placed on the right-hand side is equal in weight to what is on the left-hand side. Solving an equation can also be thought of in terms of adding weight to the left or right-hand side of the scale to balance it out.

Finding the solution to the equation involves manipulating the weights. Whatever is done on the right-hand side of the scale must also be done on the left-hand side to keep the scale balanced.

Your tools for this happen to be, most commonly, addition, subtraction, multiplication, or division.

Answer:

An equation uses symbols and numbers there are SO many equations you could make for example an easy one 6 x 5 = 30 there are two numbers you multiply to get a product. Whenever you write an equation you always put an equal sign which is this: = . This shows what you get from the equation. There are main parts the =, +, -, x, ÷ . All represent what you do to the two numbers you put on both sides of it.
