The ratio of Oats to Maple syrup for 36 cookies is 192 grams: 816 grams. So the answer is Option C. 192 grams: 816 grams.
What is Ratio:Comparing two amounts of the same units and determining the ratio tells how much of one quantity is in the other.
when evaluating the relationship between two quantities or numbers. In general, x: y, which can be interpreted as "x is to y," is used to denote a ratio between two quantities.
Here we have
15 Cookies need 80g Oats
=> Amount of Oats for 1 cookie = 80g/15 gms
So the amount Oats for 36 Cookies = 80g/5 × 36 = 192 grams
15 Cookies need 340 grams of Maple syrup
=> Amount of Maple syrup for 1 cookie = 340/15 gram
So the amount of Maple syrup for 36 cookies = (340/15)×36 = 816 grams
By the above calculations,
For 36 Cookies we need 192 grams of Oats and 816 grams of Maple syrup
The Ratio of Oats to Maple syrup = 192 gram: 816 gram
Therefore,
The ratio of Oats to Maple syrup for 36 cookies is 192 grams: 816 grams. So the answer is Option C. 192 grams: 816 grams.

An engineer looks up at the top of a cell tower. The engineer stands 30 meters from the center of the tower with a line of sight of 37° from the horizontal. The engineer's eyes are 2
meters above the ground.
The value of the tangent of angle 37° is 3/4. Then the height of the cell tower will be 24.5 meters.
What is trigonometry?Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.
A specialist gazes toward the highest point of a cell tower. The specialist stands 30 meters from the focal point of the pinnacle with a view of 37° from the level. The designer's eyes are 2 meters over the ground.
Let 'h' be the height of the tower. Then we have
tan 37° = (h - 2) / 30
Simplify the equation, then we have
tan 37° = (h - 2) / 30
3/4 = (h - 2) / 30
4h - 8 = 90
4h = 98
h = 24.5 meters
The level of the cell pinnacle will be 24.5 meters.

What is probability ?Calculating or estimating how likely or "possible" something is to occur is the subject of probability. Words like "certain," "impossible," or "probable" can be used to express the likelihood of an event occurring. Probabilities in mathematics are always expressed as fractions, decimals, or percent with values ranging from 0 to 1.
Here,
Step 1: We see that a coin is tossed 100 times, but we only receive heads 27 times.
In other words, the odds of a head are 27/100 or 0.27.
It is thought that there will be an equal number of heads and tails on a fair coin (or very close, if not equal).
So, using a fair coin:
P(H)=P(T)=0.5
Step 2
But in this instance, P(H)=0.27, which is a long way from 0.5.
Therefore, coin is unfair.
It is true that the coin can be considered unfair.

By solving an inequality, we will see that option a is cheaper for more than 60 miles.
For what number of miles is option A better?We know that option A charges $25 per day plus $0.15 per mile, so the cost for x miles is given by the linear equation:
A(x) = $25 + $0.15*x
While for option B the fixed cost is $10 and the cost per mile is $0.40, so the cost equation is:
B(x) = $10 + $0.40*x
The cost of option a will be smaller when:
$25 + $0.15*x < $10 + $0.40*x
$25 - $10 < $0.40*x - $0.15*x
$15 < $0.25*x
$15/$0.25 < x
60 < x
So for 60 miles the cost is the same, for x > 60 miles the cost of option a will be smaller (because the slope is smaller).

Find the values of x and y.
Answer:
x = 90 , y = 43
Step-by-step explanation:
Since AB and AC are congruent , then Δ ABC is isosceles with base angles congruent , that is
∠ ABD = ∠ ACD = 47°
AD is the perpendicular bisector of BC , so
∠ ADB = x = 90
the sum of the 3 angles in Δ ABD = 180° , then
y = 180° - (90 + 47) = 180 - 137 = 43

Answer:
y = 0
Step-by-step explanation:
x + 2y = 2 ( subtract 2y from both sides )
x = 2 - 2y → (1)
x = - 4y + 2 → (2)
substitute x = 2 - 2y into (2)
2 - 2y = - 4y + 2 ( add 4y to both sides )
2 + 2y = 2 ( subtract 2 from both sides )
2y = 0 , then
y = 0

Bill write 4 page per hour. I the total number of page written proportional to the number of hour pent writing?
Equation used to represent the relation between the number of pages written to the number of hours used with constant of proportionality is
x = 4y.
As given in the question,
Let us consider number of pages write by Bill be 'x'
And number of hours represented by 'y'
Number of hours used by Bill to write 4 pages = 1 hour
Number of pages written by Bill in 1 hour = 4
Given :
Number of pages is proportional to the number of hours
⇒ x ∝ y
⇒ x = ky
Where 'k' is the constant of proportionality.
When x = 4 , y = 1
substitute the value in the equation,
4 = k(1)
⇒ k = 4
Now the required equation with the constant of proportionality k = 4 is:
x = 4y
Therefore, the required equation to represent the relation between number of pages written to the number of hours used with constant of proportionality is equal to x =4y.

You deposit $600 in a savings account. After 18
months, you check your statement and see that
you have earned $31.50 in interest. What is the
interest rate for your account?
Answer:
To calculate the interest rate for your account, you will need to use the formula for simple interest:
Interest = Principal x Rate x Time
In this case, the principal is the amount of money you deposited, or $600. The time is the number of months the money was in the account, or 18 months. And the interest is the amount of money you earned, or $31.50.
Plugging these values into the formula, we get:
$31.50 = $600 x Rate x 18
To solve for the rate, we can divide both sides of the equation by $600 and 18:
Rate = $31.50 / ($600 x 18)
Simplifying this expression gives us:
Rate = 0.01625
So, the interest rate for your account is approximately 1.625%.
