Answer:
15 x 20 x 4 = 1,200
6 x 4 = 24, 24 divided by 2 ( x 1/2 ) = 12
12(area of 1 triangle) x 12(width) = 144
Formula area of a triangle:
B(base) x H(height) x 1/2(basically just dividing by 2)
Formula volume of a rectangular prism:
L x W x H
Answer:
1) 1200
2) 144
Step-by-step explanation:
1:
Volume Of A Cube: L * W * H
Substitute: 25 * 20 * 4
2:
Volume Of A Triangular Prisism: 0.5 * B * A * H
Substitute: 0.5(6 * 4) * 12

from the house is the base of the ladder?
A. 4 feet
B. 6 feet
C. 9.06 feet
D. 4.22 feet
Answers
Answer:
Distance of ladder from base = 4.22 feet (Approx.)
Step-by-step explanation:
Given:
Length of ladder = 10 feet
Angle with ground = 65°
Find:
Distance of ladder from base
Computation:
Length of ladder (hypotenuse) = 10 feet
Distance of ladder from base (Base)
Using trigonometry function
Cosθ = Base / Hypotenuse
Cosθ = Distance of ladder from base / Length of ladder
Cos65 = Distance of ladder from base / 10
0.4226 = Distance of ladder from base / 10
Distance of ladder from base = 0.4226 x 10
Distance of ladder from base = 4.226
Distance of ladder from base = 4.22 feet (Approx.)

what is the domain of the relation enter each value on the same line separated by commas. consider the relation { (9,1), (4,5), (6,2), (8,6), (1,2)}
Answers
Answer:
D = {1, 4, 6, 8, 9}
Step-by-step explanation:
A relationship maps elements from a set (the domain, the set of the inputs) into elements from another set (the range, set of the outputs).
Such that the usual notation is: (x, y)
this says that the relationship maps the element x into the element y.
In this case, we have the relation:
" { (9,1), (4,5), (6,2), (8,6), (1,2)}"
The inputs are the first value for each pair, then the set of the inputs (also called the domain) is:
D = {9, 4, 6, 8, 1}
And we can rewrite this in order to get:
D = {1, 4, 6, 8, 9}

To do this, we make use of Euler's formula
[tex]F + V - E = 2[/tex]
Where
[tex]F \to Faces; V \to Vertices; E \to Edges[/tex]
[tex](a):\ Faces = 8; Vertices = 12; Edges = 6[/tex]
Using: [tex]F + V - E = 2[/tex]
[tex]8 + 12 - 6 = 2[/tex]
[tex]14 = 2[/tex]
The above equality is false. Hence, (a) does not exist
[tex](b):\ Faces = 6; Vertices = 6; Edges = 4[/tex]
Using: [tex]F + V - E = 2[/tex]
[tex]6 + 6 - 4 = 2[/tex]
[tex]8 = 2[/tex]
The above equality is false. Hence, (b) does not exist
[tex](c):\ Faces = 20; Vertices = 30; Edges = 12[/tex]
Using: [tex]F + V - E = 2[/tex]
[tex]20 + 30 - 12 = 2[/tex]
[tex]38 = 2[/tex]
The above equality is false. Hence, (c) does not exist

A pack of clothes pins has 1 quarter yellow 2 thirds red and the rest blue how much blue pins are there
Answers
Answer: 1/12
Step-by-step explanation:
First make all the fractions have the same denominator. To do that, multiply the fractions by a number that will get them the same denominator. In this case, multiply 1/4 by 3, and 2/3 by 4.
1/4 x 3/3 = 3/12
2/3 x 4/4 = 8/12
then you have 3/12 + 8/12 = 11/12
so, blue is 1/12
Answer:
1/12 of the pins are blue
Step-by-step explanation:
¼ yellow & ⅔ red
First you have to find a common denominator.
4×3 =12 & 3×4 =12 so the common denominator is 12.
Now × the numerator on the fraction with the same number that you x the denominator and you will get 3/12 and 8/12.
3/12 +8/12 = 11/12
12/12 - 11/12 = 1/12
Therefor 1/12 of the pins are blue

Answer:
Hello, so the answer is 21.
Step-by-step explanation:
Okay so first we want to do it order, so the order you do it in is the order of PEMDAS which stands for Parentheses, Exponents, Multiplication, Division , Addition and Subtraction.
So in this situation we have parenthesis, multiplication, subtraction and addition, so we start with the parenthesis, (8 x 3) which is 24. So then we move on to +6 (positive six) and -9 (negative 9) basically -9 minus 6 is -3.
Sooo now we have -3 and 24. The three is negative because -9 minus 6 is -3, and you have to put the sign of the bigger number.
Now, 24 minus 3 equals 21. So there we have it :)

Compare the triangles and determine whether they be proven congruent, if possible, by SSS, SAS, ASA, AAS, or HL. Write your answer in the box.
Answers
========================================================
Explanation:
The sides shown by the single tickmark are the same length. That's one "S" of "SSS".
The sides shown with double tickmarks are the same length. This is another "S" of "SSS".
Lastly, the third unmarked sides of each triangle overlap together perfectly. We consider this a shared side. They are the same length due to the reflexive property. This is the third "S" of "SSS".
The order of the "S" terms mentioned above doesn't matter. All that matters is that we have three pairs of congruent sides. This is enough to use the SSS congruence theorem to prove the two triangles are congruent.
--------------
Extra info:
We don't have any information about the angles, so we cannot use ASA, SAS, or AAS.
We can't use HL because that only applies to right triangles.
Santiago buys a new computer for $3000. He pays it off in 2 years and pays $480 in simple interest. What was the interest rate?
Answers
Answer:
8%
Step-by-step explanation:
We can solve this by making use of the simple interest formula
I= PRT/100
480= 3000×R×2/100
480= 6000R/100
Cross multiply
48000= 6000R
R= 48000/6000
= 8%
Hence the rate is 8%
