Answer:

c = -8

Step-by-step explanation:

c/2 + 5 = 1

Move number 5 next one. Basicly one side it number one side are for letters. but the sings change. + tunrs to - - turns to +. x turns into / / turns into x

c/2+ 5 -5 = 1 -5

Simplify

c/2 = -4

Multiply all terms by the same value to eliminate fraction denominators

c/2= -4

2 x c/2 = 2 ( -4 )

Simplify

2 x c/2 (cross out both of the twos)

c= 2 (-4)

c=-8

Hope this helps =)

A sequence is constructed according to the following rule: its first term is 7, and each next term is one more than the sum of t

Iteru [2.4K]

Answer:

Step-by-step explanation:

According to the described rule, we have

$a_1=7\\ \\a_1^2=7^2=49\Rightarrow a_2=4+9+1=14\\ \\a_2^2=14^2=196\Rightarrow a_3=1+9+6+1=17\\ \\a_3^2=17^2=289\Rightarrow a_4=2+8+9+1=20\\ \\a_4^2=20^2=400\Rightarrow a_5=4+0+0+1=5\\ \\a_5^2=5^2=25\Rightarrow a_6=2+5+1=8\\ \\a_6^2=8^2=64\Rightarrow a_7=6+4+1=11\\ \\a_7^2=11^2=121\Rightarrow a_8=1+2+1+1=5\\ \\\text{and so on...}$

We can see the pattern

$a_5=a_8=a_{11}=a_{14}=...=5\\ \\a_6=a_9=a_{12}=a_{15}=...=8\\ \\a_7=a_{10}=a_{13}=a_{16}=...=11$

In other words, for all $k\ge 2$

$a_{3k-1}=5\\ \\a_{3k}=8\\ \\a_{3k+1}=11$

Now,

$a_{2018}=a_{3\cdot 673-1}=5$

Find the length of YZ

emmainna [20.7K]

Larger triangle’s base length

a^2 + b^2 = c^2
a^2 + 3^2 = 8^2
a^2 = 8^2 - (3^2)
sqrt(a^2) = sqrt(55)
a = sqrt(55)
__________________

Smaller triangle’s base length:

The same formula applies.
a^2 + 3^2 = 5^2
a^2 = 5^2 - (3^2)
sqrt(a^2) = sqrt(16)
a = 4
____________

The finale!

Add the two side lengths of a, which is sqrt(55) + 4 (exact answer)
or... 11.416 (unrounded to thousandths place)

Good luck to you!

This bottle holds 720ml.It is 3/8 full.How much liquid is in the bottle?

chubhunter [2.5K]

Answer: It should be 270 ml

Step-by-step explanation:

To find 3/8 of 720, we need to know 1/8

Divide 720 by 8, this gives you 90

Now multiply 90 by 3 to get 3/8

Answer is 270 ml
