Are these triangles similar?
Answer:
B. Yes, by the AA Similarity Postulate
Step-by-step explanation:
This triangles are both similar based on the AA Similarity Postulate. We know that all angles are equal because...
m∠ABE = m∠CBD = 42° (because they are veridical/opposite angels)
m∠AEB = 180° - m∠ABE - m∠EAB = 180° - 42° - 53° = 85°
Then from here we know that
m∠BDC = 180° - 85° - m∠CBD
m∠BDC = 95° - 42°
m∠BDC = 53°
From here we see that they are similar because of the AA Similarity Postulate, since
m∠ABE = m∠CBD = 42°
m∠BDC = m∠EAB = 53°
m∠AEB = m∠BCD = 85°

6th term 25,75,225,675,.... is it arithmetic or geometric. what's the explicit equation and the given term
Answer:
see explanation
Step-by-step explanation:
There is a common ratio r between consecutive terms, that is
[tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{75}{25}[/tex] = 3
[tex]\frac{a_{3} }{a_{2} }[/tex] = [tex]\frac{225}{75}[/tex] = 3
[tex]\frac{a_{4} }{a_{3} }[/tex] = [tex]\frac{675}{225}[/tex] = 3
This indicates the sequence is geometric with explicit formula
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 25 and r = 3 , then
a₆ = 25 × [tex]3^{5}[/tex] = 25 × 243 = 6075

There are 40 animals in Mang Roman's farm.The ratio of cows to carabaos to goats to horses is 4:2:3:1. How many animals of each kind are there in Mang Roman's farm.
Answer:
there are
16, 8, 12 and 4 different animals
Step-by-step explanation:
Step-by-step explanation:
Step one:
given data
Number of Animals = 40
The given ratio is = 4:2:3:1
The total ratio is = 4+2+3+1= 810
Step two;
Applying the part to all method
The first animal
4/10=x/40
cross multiply
10x= 40*4
divide both sides by 10
x= 160/10
x= 16
for second we have
2/10=x/40
cross multiply
10x= 40*2
divide both sides by 10
x= 80/10
x= 8
for the third we have
3/10=x/40
cross multiply
10x= 40*3
divide both sides by 10
x= 120/10
x= 12
for the fourth we have
1/10=x/40
cross multiply
10x= 40*1
divide both sides by 10
x= 40/10
x= 4

A coin has heads on one side and tails on the other. The coin is tossed 50 times and lands
heads up 19 times. How does this frequency compare to the expected frequency based on
the probability of the coin landing with heads up?
Answer: A “The Frequency is 31 lower than expected.”
Step-by-step explanation:
The frequency is 12 fewer than expected.
What is relative frequency?Relative frequency or experimental probability is calculated from the number of times an event happens, divided by the total number of trials in an actual experiment.
The experimental relative frequency at which the coin lands heads up is [tex]\frac{19}{50}[/tex] or 0.38.
If the coin were a fair one, we would expect that it had heads up 25 out of 50 times, which would be a relative frequency of 0.50.
Since this is not happening, we conclude that the coin is NOT a fair one.
Expected frequency = 0.50
Experimental relative frequency = 0.38
= 0.50 - 0.38
= 0.12 or 12 %
Hence, the frequency is 12 fewer than expected.

Sara went shopping. She bought six oranges at $0.25 each, two apples at $0.40 each, three plums at $0.18 each. She gave the cashier $5.00. How much change will Sara receive from the $5.00?
Answer:
$2.16
Step-by-step explanation:
Amount of change received
= $[5.00-0.25(6)-0.40(2)-0.18(3)]
= $(5.00-1.50-0.80-0.54)
= $2.16
A cat chased after a dog for l mile, and then stop to rest. As soon as the cat sotped,the dog chased after the cat for 1500 yard back towards their starting point. How many yards were the ainmals for her starting point?
Answer:
0.14768 mile
Step-by-step explanation:
Given that:
Distance at which cat chased dog = 1 mile ; hence they've moved 1 mile from their starting position
Distance for. Which dog chased cat =. 1500 yards towards starting position
Converting miles to yards
1 mile = 1760 yards
1 yard = 0.000568 mile
Number of miles the animals are from Their starting position :
1760 yards - 1500 yards = 260 yards
260 * 0.000568 = 0.14768 mile

Answer:
12
Step-by-step explanation:
The required equation of the line that is parallel to the given line is 4y - 10x = 12. Option B is correct.
Given that,
Which equation represents a line parallel to the line whose equation is 2y - 5x = 10 is to be determined.
What is the slope of the line?
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The property of the parallel line state that the slope of the parallel line are always equal.
So the slope of line given in B 4y - 10x = 12 is m = 5 and slope of the given line is m = 5 which are equal.

A king owned land outside of his castle he has partitioned the land to give as gifts to his 5 sons what fraction of land did the king give to each of his sons here is zeke solution andy got 1/2 bill got 1/5 carl got 1/5 dirk got 1/8 and evan got 1/8 identify zeke's two errors correct them and explain why your answers are correct
Picture relating to the question is attached
Answer:
Andy = 1/2
Bill = 1/8
Carl = 1/8
Evan = 1/8
Dirk = 1/8
Step-by-step explanation:
According to the picture depicting the sharing of the land :
Fraction of the total rectangular plot = 1
Andy got a portion of the whole divided into 2 = 1/2
Fraction left after Andy's portion:
1 - 1/2 = 1/2
1/2 of the fraction left was divided equally between Dirk and Evan
Hence ;
1/2 of 1/2 = 1/2 * 1/2 = 1/4
Dirk's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
Evan's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
Fraction of land left :
1 - (1/2 + 1/8 + 1/8) = 1 - 3/4 = 1/4
1/4 was divided equally into 2 for Bill and Carl:
Bill's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
Carl's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8

(5x - 15) - (2x + 5) = 3x - 20
(2x + 5) - (5x - 15) = - 3x + 20
The sum is ___
Step 1: Simplify both sides of the equation.
5x−15−(2x+5)=3x−20
5x−15+−1(2x+5)=3x−20(Distribute the Negative Sign)
5x+−15+−1(2x)+(−1)(5)=3x−20
5x+−15+−2x+−5=3x−20
5x+−15+−2x+−5=3x+−20
(5x+−2x)+(−15+−5)=3x−20(Combine Like Terms)
3x+−20=3x−20
3x−20=3x−20
Step 2: Subtract 3x from both sides.
3x−20−3x=3x−20−3x
−20=−20
Step 3: Add 20 to both sides.
−20+20=−20+20

z°=(5x-10)°[Being the pair of vertically opposite angle]
z+70°=180[Being the pair of straight angle]
or, z=180-70
z= 110
Again ,
z=(5x-10)°

MARKING BRAINLIEST IF YOU ACTUALLY TRY
Answer:
Elena could tell without finishing by simplifying both sides. The next step would have been 30x +24x = 30x+24. This would have been simplified down to x=1
Step-by-step explanation:
She got to the last line 36x + 18 = 36x + 18 when she stopped and said the equation has infinitely many solutions.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equation is given as,
12x +6(4x + 3) = 6(6x + 4) - 6
Simplify the equation, then we have
12x +6(4x + 3) = 6(6x + 4) - 6
12x + 24x + 18 = 36x + 24 - 6
36x + 18 = 36x + 18
She got to the last line 36x + 18 = 36x + 18 when she stopped and said the equation has infinitely many solutions.
