The perimeter of triangle ABC is 138 cm and BC || DE. Is triangle ABC = triangle ADE? Which conjecture supports your conclusion?
please help me it’s due in 30 minutes!!
Answers
Answer
yes triangle ABC is equal to triangle ADE
Step-by-step explanation:
x=46 cm, I got this after simplifying the equation of triangle ABC, x+4+x-4+x=138 cm, so this equation simplifies to 3x as +4-4 cancels out and there're 3 x's, so divide 138 by 3 and you get 46 cm, so AB is 50 cm, BC is 42 cm, and AC is 46 cm, this means EA is equal to EC, now here come a property of equality, EC attaches 2 parallel lines, as does DB, this means these 2 lines are transversals, so a number of angles are equal as well, corresponding angles are congruent, a.k.a equal to each other along with alternate interior angles, so since line DB AND line EC are transversals, we can deduce angle ADE is congruent to angle ABC, and angle DEA is equal to ACB, this mean we have 2 congruent angles, and 1 congruent set of sides, this mean that the 2 triangles are congruent due to Angle Angle Side, if your teacher doesn't use these terms, look it up, but the answer in short is yes, they are congruent or equal
We proved that ABC = triangle ADE by the concept of vertically opposite angles and given perimeter.
What is congruency?We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.
We know when a transversal intersects two parallel lines vertically opposite angles are equal hence DE ≅ CB.
Given, (x + 4) + x + (x - 4) = 138.
3x = 138.
x = 46.
Now, BC = ED = (46 - 4) = 42 cm.
Assuming DA to be y.
∴ 46 + 42 + y = 138.
y = 50
And AB = x + 4 = 50 hence proving triangle ABC = triangle ADE.

Mary earns $12 per hour, plus 10% commission on all her sales. Mary worked 10 hours and her sales were $1,500. How much money
did Mary earn?
Answers
First, you multiply 12 and 10 to get how much money she earned in 10 hours. She earned 120 dollars in 10 hours. Next, you multiply 10% and 1500. You turn 10% into 0.10, and multiply by 1500 to get 150. Finally you would add 150 and 120 to get $270. Mary earned $270.

Answers
explanation:
we know that 2 CDs and 6 DVDs cost $156 and 1 CD and 9 DVDs cost $210.
this gives us the equations:
2x + 6y = 156
and
1x + 9y = 210
where x is CDs and y is DVDs
multiply the top equation by 9 and the bottom by -6 to solve for x:
18x + 54y = 1404
-6x - 54y = -1260
add from top to bottom:
12x = 144
divide both sides by 12 to get:
x= $12
Fatima invests a total of $29,000 in two accounts. The first account earned a rate of return of 11%. However, the second account suffered a 7% loss in the same period. At the end of one year, the total of money gained was $1,570.00. How much was invested into each account?
Answers
Step-by-step explanation:
given data:
gained = $1,570
amount invested = $29,000
0.11x – 0.07( $29,000 – x ) = 1540
0.11x – ( 2030 – 0.07x ) = 1540
0.11x + 0.07 = 1540 +2030
0.18x = 3570
divide both sides by 0.18
x = 19833.33 ( amount invested at 11%.
$29,000 – 19833.33
= $9166.7 ( amount invested at 7%)

You are designing a hike that starts at the top of the canyon, above sea level. You plan to stop at three locations: •a scenic landmark, which is at sea level •famous boulder, which is below sea level •the bottom of the canyon, which is 600 feet below sea level
Answers
Answer:
Hello your question is incomplete attached below is the complete question and solution as well as the detailed solution
Step-by-step explanation:
The total change in elevation as represented in the number line is
600 - 600 = 0 ( sea level )
below sea level = 0 - 200 = -200 (where the famous boulder is located)
-200 -400 = - 600 feet ( bottom of canyon)
Sam travel 20 miles in three hours. Sam walked part of the distance at a speed of 4 mph. Sam rode his bicycle for the remaining distance at a speed of 12 mph. How many hours did Sam spend walking? How many hours did Sam spend biking?
Answers
Answer:
Sam sokey 0.5 hours biking and 3.5 hours walking
Step-by-step explanation:
Here, we want to know the number of hours spent walking and biking
Mathematically; distance = speed * time
Let the number of hours spent walking be x and the number of hours spent biking be y
Mathematically;
x + y = 3 •••(i)
distance spent walking = 4 * x = 4x miles
distance spent biking = 12 * y = 12y miles
4x + 12y = 20
divide through by 2
2x + 6y = 10 ••••••(ii)
From i , x = 4-y
Substitute this into ii
2(4-y) + 6y = 10
8 - 2y + 6y = 10
8 + 4y = 10
4y = 10-8
4y = 2
y = 2/4 = 0.5 hours
The number of hours spent walking = 4-0.5 = 3.5 hours

(C) Divide: 124 ÷ 20 = 6.2
(D) Subtract: 124 – 24.8 = 99.2
(E) Add: 124 + 24.8 = 148.8
(F) Subtract: 124 – 6.2 = 117.8

Given parameters:
Number of strikeouts last year = 124
Percent reduction = 20%
Unknown:
Number of strikeouts this year =?
Solution:
To find the number of strikeout this year,
Convert 20% to a decimal = [tex]\frac{20}{100}[/tex] = 0.2
Now; Multiply: 0.2 × 124 = 24.8
The number of strikeouts this year = 124 - 24.8 = 99.2
