Help me if you are good at finding areas please? A sticker on the rear window of a truck is rectangular in shape with two green triangular sections, as shown below. The two triangles are similar. If AB = 12 cm, BC = 6 cm, and EF = 4.5 cm, what is the total area for both triangles? (Check the picture)
Answers
Answer:
[tex]\frac{x}{y}[/tex]45 long
Step-by-step explanation:
The total area of both the triangles is 56.25 square units.
What is the scale factor of similar triangles?When two triangles are similar, the reduced ratio of any two corresponding sides is called the scale factor of the similar triangles.
What is area?The space occupied by a flat shape or the surface of an object is called area.
What is the formula for area of triangle?Area = (1/2) × base × height
According to the given question.
We have a two triangles, which are similar to each other.
Let the length of the side DE in triangle DEF be x.
Since, ABC similar to DEF
⇒[tex]\frac{AB}{DE} =\frac{BC}{EF}[/tex]
⇒[tex]\frac{12}{x} =\frac{6}{4.5}[/tex]
⇒[tex]\frac{12(4.5)}{6} = x[/tex]
⇒[tex]2(4.5)=x[/tex]
⇒ [tex]x = 9[/tex]
Now, area of triangle ABC = [tex]\frac{1}{2}(6)(12)=36 square units[/tex]
Area of triangle DEF = [tex]\frac{1}{2} (9)(4.5)= 20.25square units[/tex]
Therefore,
The total area for both the triangles
= 36 + 20.25
= 56.25 square units
Thus option B is correct.

Suppose WX = 4x - 8 and WZ = 2x + 2. Solve for x
Answers
Answer: 5
Step-by-step explanation:
Because the shape is a kite we can tell that WX and WZ are congruent.
So 4x-8 = 2x+2
Add 8 to both sides
4x = 2x+10
Subtract 2x
2x = 10
Divide by 2
x = 5
A certain drug is made from only two ingredients: compound A and compound B. There are 3 milliliters of compound A used for every 4 milliliters of compound B. If a chemist wants to make 378 milliliters of the drug, how many milliliters of compound B are needed?
Answers
Answer:
216 milliliters
Step-by-step explanation:
Since, there are 3 milliliters of compound A used for every 4 milliliters of compound B.
Therefore,
A : B = 3 : 4
Let the common multiplier of the given ratios be x.
So, A = 3x & B = 4x
Since, chemist wants to make 378 milliliters of the drug.
Therefore, total volume of drug = 378 milliliters.
3x + 4x = 378
7x = 378
x = 378/7
x = 54
4x = 4*54 = 216
Thus, 216 milliliters of compound B are needed.

Step-by-step explanation:
5 sides
(180 x 5) - 360 = 540° total of interior angles
540 - 90 - 90 = 360° total for the 3 unknown angles

Find the approximate length of the line AB PLZZZZZZZZZZZZZZZZZZ HELPPPPPP
Answers
Answer:
Approximate length of line AB is 8.6
Step-by-step explanation:
Input Data :
Point 1 (xA, yA) = (8, 2)
Point 2 (xB, yB) = (3, 9)
Objective :
Find the distance between two given points on a line?
Formula :
Distance between two points = √(xB − xA) ^2 + (yB − yA)^2
Solution :
Distance between two points = √(3 − 8) ^2 + (9 − 2) ^2
= √(−5) ^2 + 7^2
= √25 + 49
= √74
= 8.6023
Distance between points (8, 2) and (3, 9) is 8.6023

Answer:
First choice
12.0
Step-by-step explanation:
Make a right triangle, drawing straight lines, down from point A and left from point B. Use the pythagorean theorum to solve.
I will use "x," "y," and "z" as sides of the triangle as to not confuse between points a and b.
Line AB is line z
x^2 + y^2 = z^2
8^2 + 9^2 = z^2
64 + 81 = z^2
145 = z^2
(find square roots of both)
12.0416 = z

A national study report released by the Center for Studying Health System Change (HSC) in 2010, indicated that 20.9% of Americans were identified as having medical bill financial issues. Many people in families with problems paying medical bills in 2010 experienced severe financial consequences from their medical debt, with about two-thirds reporting problems paying for other necessities and a quarter considering bankruptcy, the study found. What if a news organization randomly sampled 400 Americans from 10 cities and found that 90 reported having such difficulty. A test was done to investigate whether the problem is more severe among these cities. The result of this test is ________.
Answers
Answer:
The result of this test is 0.2156
Step-by-step explanation:
Given the data in the question;
The proportion of Americans having medical bill financial issues is ;
p = 20.9% = 0.209
CLAIM;
The problem is more severe among the cities
so
H₀ : p = 0.209
H₁ : p > 0.209 { this is our claim }
population n = 400
number of people that reported difficulty x = 90
so
sample proportion p" = x / n = 90 / 40 = 0.225
Test Statistics;
z = [ (p"-p) / √( (p(1-p))/n ) ]
we substitute
z = [ (0.225 - 0.209) / √( (0.209(1-0.209)) / 400 ) ]
z = [ 0.016 / √0.0004132976 ]
z = [ 0.016 / 0.0203297 ]
z = 0.787
P-VALUE
p-value = P( Z ≥ z )
p-value = P( Z ≥ 0.787 )
p-value = P( Z ≤ -0.787 )
from normal distribution table;
p-value = P( Z ≤ -0.787 ) = 0.2156
p-value = 0.2156
Therefore, The result of this test is 0.2156

Triangle G F E is cut by line segment H J. Line segment H J goes from side G E to F E. The length of G F is 4 x minus 4, the length of H J is x + 3, and the length of J E is x minus 1.
If H is the midpoint of GE and J is the midpoint of FE, determine the following lengths.
HJ =
JE =
Answers
Answer:
HJ = 8 JE = 4
Step-by-step explanation:
it is given that H is the midpoint of GE and J is the midpoint of FE. According to the midpoint theorem the line segment connecting the midpoint of two sides is parallel to the three side and its length is half of the third side. since JH is connecting the midpoints.
HJ= 1/2 (GF)
x + 3 = 1/2 (4x - 4)
x + 3 = 2x - 2
x = 5
^ Thus meaning the value of x is 5.
Now you just fill into your equations:
HJ = x + 3 = (5) + 3 = 8
JE = x - 1 = (5) - 1 = 4
Therefore, HJ = 8; JE = 4.
Answer:
HJ = 8
JE = 4
