When taking the sine and cosine of different angles in your calculator, why are they sometimes the same? Why do they sometimes produce the same answer? ex: sin 55* = 0.819152044 and cos35* = 0.819152044 or sine 30* and cos 60*
Answer:
sin(theta) = 90 - cos(theta)
cos(theta) = 90 - sin(theta)

Liz flips a coin 50 times. The coin lands heads up 24 times and tails 26 times. Based on Liz’s results, what is the experimental probability of the coin landing on heads?
Answer:
48%
Step-by-step explanation:
First, lets start with what we know.
Coin was flipped 50 times. Landed Heads 24 times, and landed tails 26 times.
Now, we want this in a percentage. So:
24 = x
50 = 100
We know that 50 is 100/2. So, we can multiply both of the numbers to get a percentage.
24 × 2 = 48
26 × 2 = 52
In conclusion, the experimental probability for the coin landing on heads is:
48/100 OR 48%
11. Kona wants to bake at most 30 loaves of banana bread and nut bread for a bake sale. Each loaf of banana bread sells for $2.50, and each loaf of nut bread sells for $2.75. Kona wants to make at least $44. Let x represent the number of loaves of banana bread and let y represent the number of loaves of nut bread Kona can bake. Write a system of inequalities to model the situation.
12. What is a combination of loaves of banana bread and loaves of nut bread that would be a solution to the system from problem 11?
Answer:
x + y ≤ 30
2.5x + 2.75y ≥ 44
At the gym, Jasper was able to bench press 224 pounds, which was StartFraction 7 over 8 EndFraction of the weight that Balin was able to bench press. Which shows the correct equation and value of x, the weight that Balin could bench press
Answer:
Balin could bench press 256 pounds.
Step-by-step explanation:
Jasper was able to bench press 224 pounds, which is 7/8 of x, which is the weight that Balin was able to bench press. So, mathematically:
[tex]\frac{7}{8}x = 224[/tex]
[tex]7x = 224*8[/tex]
[tex]x = \frac{224*8}{7} = 256[/tex]
Balin could bench press 256 pounds.

Answer:
$82.22
Step-by-step explanation:
Price of meal before discount: $78.31
They leave a 20% tip that applies to the cost of the meal before the discount, so the tip is 20% of $78.31.
Now we calculate the amount of the tip.
20% of $78.31 =
= 0.2 * $78.31
= $15.66
The tip is $15.66. We will apply it later after we use the discount.
The meal's original price was $78.31 before the discount.
The discount is 15%. Now we find the amount of the discount.
15% of $78.31 =
= 0.15 * $78.31
= $11.75
The discount due to the coupon is $11.75
The final price of the meal is the original price, minus the discount, plus the tax.
final price = $78.31 - $11.75 + $15.66 = $82.22

Show work
Answer:
Step-by-step explanation:
Given functions are,
f(x) = 2x - 3
g(x) = x³ - 2
h(x) = x² - 3x + 5
(10). f(4) = 2(4) - 3
= 5
g(-2) = (-2)³ - 2
= -8 - 2
= -10
f(4) + g(-2) = 5 -10 = -5
(11). g(3) = 3³ - 2 = 25
h(1) = 1² - 3(1) + 5
= 1 - 3 + 5
= 3
g(3) - h(1) = 25 - 3 = 22
(12). f(2) = 2(2) - 2 = 2
h(-3) = (-3)² - 3(-3) + 5
= -27 + 9 + 5
= -13
f(2).h(-3) = 2(-13) = -26

Two side length of a triangle are given as 9 cm and 5 cm. What could be the length of its third side?
Answer: Two sides are given 5 cm and 9 cm. .Therefore, the third side can not be greater than or equal to (9+5)=14 cm and it can not be less than or equal to (9–5)=4 cm
Step-by-step explanation:
Please Give me brainliest
Answer:
Step-by-step explanation:
the length to the third side can be
a) a^2+b^2=c^2
a=9, b=5
c^2=81+25=106
c=sqrt106=10.29
or
a=5, c=9
b^2=c^2-a^2
b^2=81-25=56
b=sqrt56=7.48
Find the value of x.
Answer:
x = 18°
Step-by-step explanation:
The sum of interior angles of any polygon is given by:
180(n -2) , where n is the number of sides of that polygon.
So for this pentagon;
The sum of its interior angles = 540°
∴
90 + (9x -6) + (3x + 23) + 95 + (7x - 4) = 540
19x + 198 = 540
19x = 540 - 198 = 342
x = 342 ÷ 19 = 18°

Donovan can type 45 words per minute. He needs to type a report that is 9 pages long. Each page has about 300 words. What is a reasonable amount of time for Donovan to type the report?Answer options with 4 optionsA.30 minutesB.45 minutesC.60 minutesD.75 minutes
Answer:
60
Step-by-step explanation:
He needs to write 300*9 pages which is 2700
We know that he writes 45 pages a minute
his speed can be shown through the following equations
45x=pages typed
where x=minutes
so we set up our problem
45x=2700
we divide by 45 and get x=60

A borrower has a monthly payment of $1,980 on a loan with a monthly constant of 6.45. What is the loan amount (to the nearest hundred)
Answer:
loan amount = $307,000
Step-by-step explanation:
given data
monthly payment = $1,980
monthly loan constant = 6.45
to find out
loan amount
solution
we get here loan amount that is express as
loan amount = ( monthly payment ÷ monthly loan constant ) × 1000 .........1
put here value
loan amount = ( 1980 ÷ 6.45 ) × 1000
loan amount = $307,000
The are of a rectangular picture frame is 93.5 square inches. The are formula for a is A=l•w. Write and solve an equation to find the width, w, of the picture frame
I will give the brainliest plzz help me
The width of the the rectangular picture frame is equals 8.5 inches
What is the width of a rectangle?A rectangle has four sides, but because the sides are paired, there are only two unique dimensions. Conventionally, the width is the shortest of these two dimensions, but when the rectangle is presented as lying on its side, the horizontal side is usually called the width.
Given here, the formula as A = l × w and the length l = 11 inches and area of a rectangular picture frame is 93.5 square inches
thus, using the formula we get ⇒ 93.5 = 11 × w
⇒ w = 93.5/11
⇒ w = 8.5 inches
Hence, The width of the the rectangular picture frame is 8.5 inches
