Answer: Monica
Step-by-step explanation:
Given
Monica has a 20% chance of winning a prize
Brianne has a [tex]\frac{1}{10}[/tex] chance of winning a prize
20% chance refers to
[tex]\dfrac{20}{100}=\dfrac{2}{10}[/tex]
As
[tex]\dfrac{2}{10}>\dfrac{1}{10}[/tex]
therefore, monica is more likely to win the prize.
Verify the identity. (cos x/ 1+ sin x) + (1+ sin x/cos x) = 2 sec x
Answer:
LHS
[tex]\frac{cos x}{1+ sin x} + \frac{1+ sin x}{cos x} \\=\frac{cos2(x)+1+2sin(x)+sin2(x)}{cos(x)(1+sin(x)} \\= \frac{2+2sin(x)}{cos(x)(1+sin(x))} \\\\=\frac{2 (1 + sin(x))}{cos(x)(1+sin(x))} \\= \frac{2}{cos (x)} \\= 2 sec x[/tex]
= RHS PROVED

Step-by-step explanation:
A square garden has sides that are 17 meters long. Fencing costs $9.00 per meter. How much would it
cost to put a fence around the garden?
Answer:
$612
Step-by-step explanation:
Each side of the square garden is 17 meters, and fencing costs $9 per meter. "Around" is the key word, as it indicates perimeter. So, we just need to account for each side of the garden, and not the entirety of the garden. So,
17 · 9 = 153
This means that to cover one side of the garden, it would cost $153. Now, we just need to account for all sides of the garden.
153 x 4 = 612
Answer:
The answer would be 612$ to put a fence around the garden
or 153 for 17 meters
Step-by-step explanation:
I believe that it is 612 because it says sides
let me know if it is correct
A storeowner plans to have his annual "Going Out of Business Sale." If each month has an equal chance of being selected, find the probability that the sale will be in a month that begins with the letter J or A.
Answer:
Step-by-step explanation:
How many months begin with J or A ? 5
How many months total? 12
The probability that the sale will be in a month begins with the letter J or A. is 5/12
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
A store owner plans to have his annual "Going Out of Business Sale." If each month has an equal chance of being selected,
The total number of months begins with J or A = 5
The total months =12

Machine machine with 140 gallon capacity needs to be filled with water/glycol mixture. Someone has already pump 50 gallons of 60% glycol blend into the machine. How much more glycol must you add an order to get a 50% concentration?
Answer:
40 gal
Step-by-step explanation:
The capacity of the machine is 140 gallons, and it must be filled.
In a 50% glycol solution, the amount of glycol in 140 gallons of solution is
50% * 140 gallons = 70 gallons.
Once the machine is full with 140 gallons of 50% glycol solution, it will have 70 gallons of glycol.
The machine now has 50 gallons of 60% glycol solution.
60% * 50 gallons = 30 gallons
The machine has now 30 gallons of glycol.
70 gal - 30 gal = 40 gal
You must add another 40 gallons of glycol.

A basketball stadium has 15 ,002 zero seats the lower level has 54 than three times as many seats as the upper level the middle level has 40 more than twice as many seats as the upper level used to solve for x and found that the upper level has 2,502 sears
Answer:
There are 7456 seats on the lower level and there are 5044 seats on the middle level.
Step-by-step explanation:
Let 'X" be the number of seats on the upper level. Then we can find how many seats are on the lower level by solving the following equation...
# of seats on the lower level = 3x - 50
# of seats on the lower level = 3(2502) - 50
# of seats on the lower level = 7456
Now we just make the equation for the number of seats on the middle level, and so we get...
# of seats on the middle level = 2x + 40
# of seats on the middle level = 2(2502) + 40
# of seats on the middle level = 5044

A triangle has sides with lengths of 26 inches, 73 inches, and 76 inches. Is it a right triangle?
Answer:
No, it is not a right triangle.
Step-by-step explanation:
We know that there are 2 legs and 1 hypotenuse. The hypotenuse is 76 because it is the largest number. And the two legs are 73 and 26. Now to find if it is a right triangle we will take 73 and multiply it by itself, which is 5,329. Now we will do the same with 26 and we get 676. Then we add 676 to 5,329 and we get 6,005. Because we are trying to find the hypotenuse, we have to find what number when squared makes 6,005. Since 76 x 76 = 5,776 it is not a right triangle.

(45 is incorrect I know that already)
Answer:
∠ B = 60°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
(10x - 45)° is an exterior angle of the triangle , then
10x - 45 = 3x + 4x = 7x ( subtract 7x from both sides )
3x - 45 = 0 ( add 45 to both sides )
3x = 45 ( divide both sides by 3 )
x = 15
Then
∠ B = 4x = 4 × 15 = 60°
Answer:
∡B=60°
Step-by-step explanation:
x = 15
so 4x = 60
7x + 180 - (10x-45) = 180
-3x + 225 = 180
-3x = -45
x = 15
