Hey there!

-11b + 7 = 40

  • SUBTRACT by 7 on each of your sides.

-11b + 7 - 7 = 40 - 7

Cancel out: 7 - 7 because that gives you 0

Keep: 40 - 7 because it helps us solve for our answer

40 - 7 = 33

  • DIVIDE both sides by -11

11b/-11 = 33/-11

Cancel out: -11b/-11 because it equals 1

Keep: 33/-11 because it gives you -3

33/-11 = 33 ÷ -11 = 3

<h3><u>b</u><u> = -3 </u></h3>

Good luck on your assignment and enjoy your day!

Answer:

b = -3

Step-by-step explanation:

<u>Step 1:  Subtract 7 from both sides</u>

-11b + 7 - 7 = 40 - 7

-11b = 33

<u>Step 2:  Divide both sides by -11</u>

<u />-11b / -11 = 33 / -11

b = -3

Answer:  b = -3

Find the m &lt; t rounded to the nearest degree
serg [7]

Answer:

28° (Answer A)

Step-by-step explanation:

Note that tan t = 8/15 = 0.533

Applying the inverse tangent function, we get

t = arctan 0.533 = 0.4900 radian

Mult. this by the radian-degree conversion factor results in:  28.072°

and when rounded off to the nearest degree, the measure of angle T is 28°  (Answer A)

You have two parents, four grandparents, eight greatgrandparents, and so forth.
Leviafan [203]
A.
In the first generation we have 2 ancestors.
In the second generation we have 4 ancestors or 2^{2} ancestors.
In the third generation we have 8 ancestors ot 2^{3} ancestors.

We can see that each succesive generation has two times more members. The sum is:
2+4+8+16+...+ 2^{40}

To calculate number of ancestors we can use formula <span>for the sum of a geometric sequence. Geometric sequence is sequence of numbers that differ by a certain factor. This factor is called ratio. Formula is:
</span>S= a_{1} * \frac{1- r^{n} }{1-r}
<span>Where:
S -> sum
a1 -> first member of a sequence
r -> ratio
n -> number of elements

For this question:
a1 = 2
r = 2
n = 40
</span>S= 2* \frac{1- 2^{40} }{1-2} =2 199 023 255 550
<span>
b.
1 generation = 25 years
40 generations = 40 * 25 = 1000 years

c.
Total number of people who have ever lived = </span>10^{10}
Number of ancestors in 40 generations = 2.2*10^{12}

The number of ancestors is greater than total number of people who have ever lived. This means that not all ancestors were distinct and that in each generation both men and women had children with more than one partner.

According to the general equation for conditional probability, if P(A upside down u B)= 5/7 and P(B)=7/8 , what is P(A|B)?
natta225 [31]
P(A | B) = \frac{P(A \cap B)}{P(B)}


P(A|B) = \frac{5/7}{7/8}


P(A|B) = \frac{5}{7} \div \frac{7}{8}


P(A|B) = \frac{5}{7}\times\frac{8}{7}


P(A|B) = \frac{5*8}{7*7}


P(A|B) = \frac{40}{49}
