What length is the real boat?
Answers
Answer:

b) The scale model is 9 inches , and the real height is H = 45 feet
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
The proportion of scale model of the boat to the real boat is 1 : 5
Now ,
a)
The height of the real boat is 15 feet and the scale model is k inches
From the proportion , we get
1 / 5 = k / 15
Multiply by 15 on both sides , we get
k = 3 inches
b)
The scale model is 9 inches , and the real height is H
From the proportion , we get
5 / 1 = H / 9
Multiply by 9 on both sides , we get
H = 45 feet
Hence , the proportion is solved

What is Cos^-1( -sq2/2)? Pleaseee help ASAPOL
Answers
Answer:
s cos^(-1)(-(q^2 s)/2) + sqrt(4 - q^4 s^2)/q^2 + constant
Step-by-step explanation:
Take the integral:
integral cos^(-1)(-(q^2 s)/2) ds
For the integrand cos^(-1)(-(q^2 s)/2), substitute u = -(q^2 s)/2 and du = -q^2/2 ds:
= -2/q^2 integral cos^(-1)(u) du
For the integrand cos^(-1)(u), integrate by parts, integral f dg = f g - integral g df, where
f = cos^(-1)(u), dg = du, df = -1/sqrt(1 - u^2) du, g = u:
= -(2 u cos^(-1)(u))/q^2 + 2/q^2 integral-u/sqrt(1 - u^2) du
Factor out constants:
= -(2 u cos^(-1)(u))/q^2 - 2/q^2 integral u/sqrt(1 - u^2) du
For the integrand u/sqrt(1 - u^2), substitute p = 1 - u^2 and dp = -2 u du:
= -(2 u cos^(-1)(u))/q^2 + 1/q^2 integral1/sqrt(p) dp
The integral of 1/sqrt(p) is 2 sqrt(p):
= (2 sqrt(p))/q^2 - (2 u cos^(-1)(u))/q^2 + constant
Substitute back for p = 1 - u^2:
= (2 sqrt(1 - u^2))/q^2 - (2 u cos^(-1)(u))/q^2 + constant
Substitute back for u = -(q^2 s)/2:
Answer: = s cos^(-1)(-(q^2 s)/2) + sqrt(4 - q^4 s^2)/q^2 + constant

The midpoint of AB is M(-3,-3). If the coordinates of A are (-5, -1), what are
the coordinates of B?
Answers
Answer:
The coordinates of B are (-1, -5).
Step-by-step explanation:
Since the x-coodinate of M is 2 greater than that of B (note that -3 = -5 + 2), the x-coordinate of B is found by adding 2 to -3, obtaining -1. The y-coordinate of M is -3, which is 2 less than the y-coordinate of A; Thus, the y-coordinate of B is 2 less than -3, that is, -5.
The coordinates of B are (-1, -5).

At an apple orchard, customers use a standard-size box when picking apples. The table shows the total weight of the box of apples and the weight of the apples alone.
Question: Which statement is true?
The equation a= 7.5t models the relationship.

If the total weight of the box is 20 lb, then the weight of the apples is 21.5 lb.

Answers
Answer:
here's the right answer- someone on a different website said the same weird thing as the person before me smh
Step-by-step explanation:
If the total weight of the box is 15 lb, then the weight of the apples is 13.5 lb.
Option (2) is correct.
What is an equation?Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics. Simple algebraic equations with merely addition or multiplication to differential equations, exponential equations with exponential expressions, and integral equations are examples of different types of equations. They are employed to represent a number of physics laws.
As per the given data:
The table shows the total weight of the box and the weight of the apples.
From the table:
Total weight of the box - weight of apples = weight of box
7.5 - 6 = 1.5 lb
10 - 8.5 = 1.5 lb
12.5 - 11 = 1.5 lb
If the total weight of the box is 15 lb and the weight of the apples is 13.5 lb
15 - 13.5 = 1.5 lb {weight of box}
Which satisfies the data in the table.
Hence, If the total weight of the box is 15 lb, then the weight of the apples is 13.5 lb.
