Answer and Step-by-step explanation:
Assuming the room is a type of rectangle, we need to divide the area by the width to get the length.
So, do 400 divided by 20 to get the length, as length times width equals the area.
400 divided by 20 = 20.
The length of the room is 20 ft. (meaning the room is a perfect square.

x : y = 5 : 3
and
x + y = 56
Work out the value of x - y
Answer:
14
Step-by-step explanation:
x / y = 5 / 3, then 3x = 5y , x = 5/3y
we can type 5/3y instead of x ;
5/3y + y = 8/3y = 56, then y = 21
.
now let's find x ;
x - 21 = 56, then x = 35
x - y = 35 - 21 = 14

Ron earned 13200 in interest on an account with a principal amount of 24000 and an interest rate of 11%. How long were the funds in the account?
Answer:
5 yearsStep-by-step explanation:
It is assumed the interest is simple.
Use the interest formula:
I = PrtWe have:
I = 13200P = 24000r = 11% = 0.11Substitute values and solve for t:
13200 = 24000*0.11t13200 = 2640tt = 13200/2640t = 5 yearsSolve the equation by factoring: 12y^3 – 13y^2 + 3y = 0
Answer:
y = 0, y = [tex]\frac{1}{3}[/tex], y = [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Given
12y³ - 13y² + 3y = 0 ← factor out y from each term
y(12y² - 13y + 3) = 0
y(3y - 1)(4y - 3) = 0 ← in factored form
Equate each factor to zero and solve for y
y = 0
3y - 1 = 0 ⇒ 3y = 1 ⇒ y = [tex]\frac{1}{3}[/tex]
4y - 3 = 0 ⇒ 4y = 3 ⇒ y = [tex]\frac{3}{4}[/tex]

Elena thinks length BC is 16.5 units. Lin thinks the length of BC is 17.1 units. Do you agree with either of them? Explain or show your reasoning.
Answer:
Option D, I agree with neither Elena nor Lin
Step-by-step explanation:
The remaining part of the question is attached herewith
Solution
As we can see in the image
ED is perpendicular to AB and BC is perpendicular to AB
Thus, as per the Pythagoras theorem,
AC^2 = AB^2 + BC^2
14^2 = 6^2 + BC^2
BC^2 = 196-36 = 160
BC = 12.649 OR 12.65
Hence, option D
I agree with neither Elena nor Lin

A teacher asks five different students to write an equation with a solution of x = 4. The students and their equations are shown below.
Student Adrian Bert Camille Daniel Etsuko Equation 2x + 6 = 2 2x-9 = -1 - 2x + 12 = 4 2(x + 2) = 10 2(x - 10) = -12
Which of the following students correctly wrote an equation with x = 4 as the solution? Select three that apply.
A. Bert
B. Daniel
C. Etsuko
D. Adrian
E. Camille
Answer:
I'm assuming the order corresponds the student to the equation. Because of this, the answer is simple:
Bert, Etsuko, and Camille.
Step-by-step explanation:
2x-9=-1, 2x=8, x=4
2(x-10)=-12, x-10=-6, x=4
-2x+12=4, -2x=-8, x=4

One angle of a right measures 79°. What is the measure of the other acute angle?
Answer:
11
Step-by-step explanation:
Sum of all angles = 180
Right angle = 90
Acute angle = 79
90+79 =169
180 -169 = 11
Answer:
11 degrees
Step-by-step explanation:
a right angle = 90 degrees
90-79=11 degrees

In a right triangle, angle θ has a cosine value of 0.755. The side adjacent to angle θ has a length of 51.5 mm. What is the length of the hypotenuse of the triangle?
68.2 mm
38.9 mm
92.5 mm
41.0 mm
Answer:
I got that it was 68.2mm.
Step-by-step explanation:
Option A is correct, the length of the hypotenuse of the triangle is 68.2 mm.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side to the hypotenuse. That is:
cos(θ) = adjacent/hypotenuse
We know that cos(θ) = 0.755 and the length of the adjacent side is 51.5 mm.
Let's denote the length of the hypotenuse by "h".
Then we can solve for "h" as follows:
cos(θ) = adjacent/hypotenuse
0.755 = 51.5/h
h = 51.5/0.755
h = 68.21 mm
Therefore, the length of the hypotenuse of the triangle is approximately 68.2 mm.

x=1? How to find coordinates::(
Answer:
Q'(1, -5)
R'(1, 1)
S'(5, -5)
Step-by-step explanation:
Since you're reflecting deflecting across x equals to 1 ,also our Q and R Coordinates are on the line x equals to 1 so it's going to stay same only the S coordinates would change. the X value for the coordinates gonna be +ve and Y value gonna be -ve. Because after the reflection of the point the point would lie in the fourth quadrant and in the Forth quadrant Xvalue is positive and Y value is negative.

Martin is interested in the effects of different kinds of instruction on videogame performance. Martin asks 30 college freshmen to each play 1 hour of Ratchet and Klank. Participants are randomly assigned to one of three instruction groups: (1) complete the tasks as quickly as possible, (2) conserve as much health as possible (i.e., play more carefully), or (3) find gold bolts (worth lots of money in equipment and ammunition). Obviously, even in a single instruction group, not all players will obtain the same final score. These differences in an instruction group reflect:
Answer:
Between - groups variance
Step-by-step explanation:
From the question we see that the college freshmen are assigned to one of the three given groups. This means that they are exposed to different experimental conditions and thus it means that the variation differs as a result of different experimental conditions between the groups.
Thus, these differences reflect between - group variance.
