Answer:

40 degrees

Step-by-step explanation:

The 100 degree angle is supplementary to angle CED. This means CED will end up being 80 degrees. Since the angles in all triangles equate to 180 degrees 80 + 60 + angle D must equal 180 degrees. Therefore, angle D has to be 40 degrees.

What is the future value of $845 a year for seven years at an interest rate of 11.3 percent? $6,683.95 $6,075.69 $8,343.51 $8,00

k0ka [10]

The future value of cash whose initial value is $845, at the rate of 11.3% for 7 years will be calculated using the compound interest rate, that is:
A=p(1+r/100)^n
where:
A=future amount
r=rate=11.3%=0.113
time=7 years
thus the future value of our cash will be:
A=845(1+0.113)^7
A=845(1.113)^7
A=$1,787.82

How Many Close Confidants Do People Have? In a recent study,1 2006 randomly selected US adults (age 18 or older) were asked to g

yaroslaw [1]

Answer:

0.08065

Step-by-step explanation:

Given that in a recent study,1 2006 randomly selected US adults (age 18 or older) were asked to give the number of people in the last six months with whom you discussed matters that are important to you.

If X is random variable then X has mean 2.2 and s = 1.4

n=2006

Std error of mean = $\frac{1.4}{\sqrt{2006} } \\=0.03126$

For 99% since sample size is large, t and z distn almost coincide.

Hence we can take 2.58 as critical value

Margin of error at 99% = $2.58*0.03126\\=0.08065$

Say you wanted to give someone 35000 berries, but every time you give someone berries, it takes away 30%. How could you calculat

VladimirAG [237]

Answer:

What I understand is that I need to give someone an exact number so that when 30% is taken, they keep exactly 35,000

To make the statement above true, we would need to divide 35,000 by 7 since the answer would be 10% of the number we need. Once we do this we get 5000 which is 10% now we multiply 5000 by 10 to get 100% and we get 50.000 once we give this amount to the person and 30% is taken away they are left with 35,000

PLEASE HELP!!!! TIMED EXAM

alexandr402 [8]

Answer:

The correct option is V = one-third (6) (4) (8).

Step-by-step explanation:

The volume of a rectangular pyramid is:

$V=\frac{1}{3}\ l\times b\times h$

Here,

V = volume

l = length

b = base

h = height

The information provided is:

l = 6 inches

b = 4 inches

h = 8 inches.

Compute the equation of the volume of a rectangular pyramid as follows:

$V=\frac{1}{3}\ l\times b\times h$

$=\frac{1}{3}\times 6\times 4\times 8$

Thus, the correct option is V = one-third (6) (4) (8).
