Answer:
x = 99°
Step-by-step explanation:
Given that,
The first angle = 40°
The second angle = 41°
We need to find the value of x. We know that the sum of angles of a triangle is equal to 180°. So, using this property.
40+41+x = 180
81+x=180
x = 180-81
x = 99°
So, the value of x is equal to 99°.

Alternate exterior angles congruent.
Which angle forms a pair of alternate
exterior angles with angle 1?
Answers
Answer:
<1 = <8
Step-by-step explanation:
Pair of alternate exterior angles are formed when two parallel lines are cut across by abl transversal line. The two angles are found on the other side of the parallel lines but located on opposite sides along the transversal line.
Thus, <1 and <8 are exterior angles of the parallel lines that are crossed by the transversal and they are on the alternate sides along the transversal.
Therefore, <1 and <8 form a pair of alternate exterior angles.
<1 = <8

A sample of 9 adult elephants had an average weight of 11,773 pounds. The standard deviation for the sample was 24 pounds. Find the 99% confidence interval of the population mean for the weights of adult elephants. Assume the variable is normally distributed. Round intermediate answers to at least three decimal places. Round your final answers to the nearest whole number.
Answers
Answer:
99% C.I of the population mean is ( 11746, 11800 )
Step-by-step explanation:
Given the data in the question;
Sample size n = 9
mean x" = 11773
standard deviation s = 24
for 99% confidence interval
∝ = 1 - 99% = 1 - 0.99 = 0.01
∝/2 = 0.01/2 = 0.005
degree of freedom df = n - 1 = 9 - 1 = 8
now, Critical t-value : [tex]t_{\alpha /2, df[/tex] = [tex]t_{0.005, 8[/tex] = 3.355
Now, at 99% Confidence interval of the mean population is;
x" ± [ [tex]t_{\alpha /2, df[/tex] × s/√n ]
we substitute
11773 ± [ 3.355 × 24/√9 ]
11773 ± [ 3.355 × 8 ]
11773 ± 26.84
so
⇒ {11773 - 26.84}, {11773 + 26.84}
⇒ ( 11746, 11800 )
Therefore, 99% C.I of the population mean is ( 11746, 11800 )

Answer: 16.81 min
Step-by-step explanation:

Half-time [tex]T_{\frac{1}{2}}=6\ min[/tex]
Decay at any time t is given by
[tex]A=A_o2^{\dfrac{-t}{T_{\frac{1}{2}}}}[/tex]
put values
[tex]\Rightarrow 139=970\cdot 2^{\dfrac{-t}{6}}\\\\\Rightarrow 2^{\dfrac{t}{6}}=6.978\\[/tex]
Taking log both sides

Last year, Lamar deposited $12,000 into an account that paid 6% interest per year and $4,000 into an account that paid 5% interest per year. No withdrawals were made from the accounts. What was the total interest earned at the end of 1 year? What was the percent interest for the total deposited?
Answers
Answer:
$920
5.75%
Step-by-step explanation:
interest earned on deposit can be determined by determining the simple interest
Simple interest = principal x time x interest rate
principal = the amount deposited
Time = the duration of the deposit
interest rate = the percentage on deposit that would be earned
$12,000 x 0.06 x 1 = $720
$4000 x 0.05 = $200
Total = $720 + $200 = $920
Percentage interest for the total deposit = (total interest earned / total amount deposited ) x 100
total amount deposited = $12,000 + $4,000 = $16,000
($920/$16,000) x 100 = 5.75%

The 5 percent sales tax on Aaron's purchase of gloves and a scarf came to $1,90 before tax the price of the gloves was $16 what was the price of the scarf before tax A. $17.10 B. $22.00 C. $39.90 D. $38.00
Answers
Answer:
$22.00
Step-by-step explanation:
sales price x .05 = $1.90
Sales price = $1.90/.05
sales price = $38.00
total sales price less price of gloves = price of scarf
$38.00 - $16.00 = $22.00

A group of 10 friends decides to head up to a cabin in the woods (where nothing could possibly go wrong). Unfortunately, a number of these friends have dated each other in the past, and things are still a little awkward. To get the cabin, they need to divide up into some number of cars, and no two people who dated should be in the same car.
a. What is the smallest number of cars you need if all the relationships were strictly heterosexual? Represent an example of such a situation with a graph. What kind of graph do you get?
b. Because a number of these friends dated there are also conflicts between friends of the same gender, listed below. Now what is the smallest number of conflict-free cars they could take to the cabin?
Friend A B C D E F G H I J
Conflicts with BEJ ADG HJ BF Al DJ B CI EHJ ACFI
c. What do these questions have to do with coloring?
Answers
Answer:
a) 3
b) 3
c) because of the permutations and combinations involved
Step-by-step explanation:
a) Determine the smallest number of cars needed
The number of cars are the same as conflict free cars
hence we can group the friends without conflict into the same car
1st car we will have : ACFI in it
2nd car we will have : GD in it
third care we will have : BEJH in it
∴ number of car needed = 3
b) number of conflict free cars = 3
c) Coloring is important in the question because of the permutations and combinations involved
