Triangles multiple choice!!
Answer:
B
Step-by-step explanation:
Using Pythagoras' identity in right triangle ABC
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
AB² + AC² = BC² , substitute values
5² + AC² = 13²
25 + AC² = 169 ( subtract 25 from both sides )
AC² = 144 ( take the square root of both sides )
AC = [tex]\sqrt{144}[/tex] = 12
Since the triangles are congruent then corresponding sides are congruent, then
DE = AC = 12 inches → B

Find the unit rate.
1/2 pound : 5 days
Answer:
= 0.2 pound per day
Step-by-step explanation:
This is a fraction equal to
1 pound ÷ 5 days
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 5
1 pound ÷ 5
5 days ÷ 5
=
0.2 pound
1 day
=
0.2 pound
day
= 0.2 pound per day

radius of a circle with a circumference of 50.26
Answer:
16 cm
Step-by-step explanation:
Circumference is equal to 2 pi r.
Isolating r gives us C/2pi = r
50.26/2pi = 8, exactly.
Diameter is equal to 2r, so the diameter is 16 cm.
Answer:

if the sum of the first n terms of the series 4+7+10+..... is 209, find n
Answer:
Step-by-step explanation:
wow, this is kinda complicated math for HS.. :? we have to know what type of series this is, and that means knowing all the different kinds.. unless maybe in the instructions it tells you you are working with arithmetic series? It is one of those so we can use those formulas... other series can have much more complex formulas.. series comes up in Calc II in college.. but .. unless you're going to be an engineer you probably don't need it.. soooooo anyway..
we can use Sn = n/2(2a1 + d(n-1) )
where d is the difference of a2 -a1 ( this will be the same for all terms)
since we're given Sn = 209 set the problem to 209 and solve for n :/
sounds hard huh.. :? let's see
209 = n/2( 2(4) + 3(n-1))
209 = n/2(8 + 3n-3)
209 = n/2(5+3n)
2*209 = n(5+3n)
418 = 3[tex]n^{2}[/tex] + 5n
0 = 3[tex]n^{2}[/tex] + 5n-418 ( use quadratic formula to find n )
( -5 ± [tex]\sqrt{5^{2}-4*3*(-418) }[/tex] ) / 2(3)
( -5 ±[tex]\sqrt{25+5016}[/tex] ) / 6
( -5 ±[tex]\sqrt{5041}[/tex] ) / 6
( -5 ± 71 ) / 6 ( they were nice to us and make it work out perfectly :) )
positive route = 71-5 /6 = 66/6 =11
negative route = 71-(-5) /6 = 71+5/6 = 76/6 = 12[tex]\frac{2}{3}[/tex]
since 12[tex]\frac{2}{3}[/tex] isn't going to really work for us... let's try 11
an= a1 + d(n-1)
an = 4 + 3(11-1)
an = 4 + 30
an = 34
now let's see if we can get 209 for our 11 terms of the series
Sn = 11/2(2(4) + 3(11-1))
Sn = 11/2(8 + 30)
Sn = 418 /2
Sn = 209 yay.. we got it.. it's the 11th term.. and thank you quadratic formula. You get a Christmas present this year :P
n = 11
The number of the terms of the sequence will be equal to 11.
What is an arithmetic progression?The sequence in which every next number is the addition of the constant quantity in the series is termed the arithmetic progression.
Given series is 4+7+10+..... and the sum of the terms of the series is 209.
The summation of the n terms of the series is written by the formula below,
Sn = n / 2 [( 2a+(n-1)d]
Substitute the values in the equation above,
209 = n / 2 [(2 x 4 + ( n -1)3]
418 = n(5+3n)
3n² + 5n - 418 = 0
The above quadratic equation will give two values of n. The values of n are,
n = 11
n = -12.55
The terms can not be equal to a negative number.
Therefore, the number of the terms of the sequence will be equal to 11.

which fraction is equivalent to 2/6
Answer:
1/3, 2/6, 3/9, 4/12..are equivalent fractions. Equivalent fraction of a given fraction is got by multiplying or dividing its numerator and denominator by the same whole number. For example, if we multiply the numerator and denominator of 2/3 by 4 we get.
Step-by-step explanation:
The equivalent fractions of the given fraction [tex]\dfrac{2}{6}[/tex] are [tex]\dfrac{4}{12} ,\dfrac{6}{18} ,\dfrac{8}{24}[/tex] .
The fractions which have the same value but can have different numerators or denominators when either multiplying , dividing or converting it into the lowest form is called equivalent fractions
The upper part of a fraction or part of a whole is called numerator and the lower part of a fraction or the whole is called denominator.
Equivalent fraction can be obtained by multiplying numerator and denominator with the same number .
Example : equivalent fraction of [tex]\dfrac{5}{8}[/tex] is
[tex]\dfrac{5}{8} = \dfrac{5 \times 1 }{8 \times 1} =\dfrac{5\times2}{8\times2} ........=\dfrac{5}{8}[/tex]
According to the data provided in the problem
[tex]\dfrac{2}{6} = \dfrac{2 \times 1 }{6 \times 1} =\dfrac{2\times2}{6\times2} ........=\dfrac{2}{6}[/tex]
Thus the equivalent fractions of [tex]\dfrac{2}{6}[/tex] are [tex]\dfrac{4}{12} ,\dfrac{6}{18} ,\dfrac{8}{24}[/tex]

determine the missing angle
Answer:
Angle A = 77, Angle B = 41
Step-by-step explanation:
Triangles add up to 180 degrees. Your equations would be 62 + (2x-5)+x=180.
Simplify: 57 + 3x = 180
Solve for x: 3x = 123
X = 41.
Then insert X to find angle A.
2(41) - 5 = 77

Side BC is 4 meters long. Side CD is twice the length of the side BC. What is the length of side LM. Explain your reasoning.
Answer:
LM = 18
Step-by-step explanation:
BC = 4
CD is twice that, so CD is 8
Now, remembering that the area of ABCD = 32 and JKLM = 72, divide 72 by 32.
You get 2.25. This is how much bigger JKLM is than ABCD.
Using that, multiply the length of CD (which is 8) by 2.25 to get the length of LM.
You'll get 18.
