Find the values of x and y.
Answers
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

To earn a "C" in Probability, Sam must get a grade average of at least 70%.
Sam's test scores are 62, 71, and 65. His final exam score counts as 3 test
scores in the average. What is the minimum score Sam needs to get on his
final exam to get a "C" in the course?
Answers
The minimum score Sam needs to get on his final exam to get a "C" in the course is 82.
What is a probability?
A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
Given that, Sam's test scores are 62, 71, and 65.
The total score in three test is (62 + 71 + 65) = 198
Assume that, he scored x in the final test.
Total score of Sam is 198 + x.
He needs to score 70% means he needs to score 70 out of 100.
According to question,
(198 + x)/ 400 ≥ 70/100
Multiply both sides by 100:
(198 + x)/ 4 ≥ 70
Multiply both sides by 4
198 + x ≥ 280
x ≥ 280 - 198
x ≥ 82

Answers
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

Answers
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.

The amount of time a certain brand of light bulb lasts is normally distribued with a
mean of 1900 hours and a standard deviation of 45 hours. Out of 670 freshly installed
light bulbs in a new large building, how many would be expected to last more than
1890 hours, to the nearest whole number?
Answers
To calculate the area under the normal distribution curve, we first need to standardize the value 1890 hours. This means we need to convert it to a z-score, which represents the number of standard deviations above or below the mean a value is. To standardize a value, we use the following formula:
z = (x - mean) / standard deviation
In this case, we have x = 1890, mean = 1900, and standard deviation = 45, so the z-score is:
z = (1890 - 1900) / 45 = -0.22
We can now use this z-score to look up the corresponding area under the normal distribution curve using a table of the standard normal distribution. This table gives the area under the curve between the mean and a given z-score. Since our z-score is negative, we need to look up the area to the left of the mean. In this case, the area is 0.4162.
We can now multiply this probability by the total number of light bulbs, 670, to find the number of light bulbs that are expected to last more than 1890 hours. This is:
0.4162 * 670 = 278.29
Rounded to the nearest whole number, this is 278 light bulbs. So we would expect about 278 out of 670 freshly installed light bulbs in the new large building to last more than 1890 hours.
The answer is 278 light bulbs.

12/24
Answers
A class is planning a trip to the local City Museum of Art. The class needs 3 trucks and 1 car to transport all 22 people on the trip.
What is the system of equations?Generally, To solve this problem, we can set up a system of equations using the information given. Let C be the number of cars needed and T be the number of trucks needed.
The first equation will represent the number of people that can be transported in the cars: 4C + 6T = 22
The second equation will represent the number of drivers: C + T = 4
Now we can solve this system of equations using elimination or substitution.
Using elimination, we can multiply the first equation by 2 and the second equation by 4 to get: 8C + 12T = 44 4C + 4T = 16
Then we can subtract the second equation from the first equation to get: 4C + 8T = 28
Then we can divide both sides by 4 to get: C + 2T = 7
Then we can substitute this value for C in the second equation to get: 7 - 2T = 4 T = 1.5
Since T represents the number of trucks, which must be a whole number, this solution is not possible.
Using substitution, we can solve for C in the second equation and substitute it into the first equation: C = 4 - T 4(4 - T) + 6T = 22 16 - 4T + 6T = 22 2T = 6 T = 3
Substituting this value for T into the second equation, we get: C = 4 - 3 C = 1

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?
Answers
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%.

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

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

Answer:
m∠QRS = 30°
m∠SRT = 75°
Step-by-step explanation:
Given;m∠QRT = 105°m∠QRS = (6x)°m∠SRT = (14x + 5)°To Find;m∠QRS and m∠SRTNow,
The sum of m∠QRS and m∠SRT is equal to m∠QRT which is 105°
So,
m∠QRS + m∠SRT = m∠QRT
(6x)° + (14x + 5)° = (105)°
6x + 14x + 5 = 105
20x + 105 - 5
20x = 100
x = 100/20
x = 5
Thus, The value of x is 5°
Now,
m∠QRS = (6x)° = 6 × 5 = 30°
m∠SRT = (14x + 5)° = 14(5) + 5 = 70 + 5 = 75°
Triangle ABC is a right triangle, with right angle B. Side AC has a
length of 13. Side AB has a length of 5. Find the length of side
CB.
Answers
The length of side BC is approximately 10.928.
What is the right triangle?
In a right triangle, the side opposite the right angle is called the hypotenuse. In triangle ABC, side AC is the hypotenuse, and sides AB and BC are the other two sides.
To find the length of side BC, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.
We can use the given information to write the Pythagorean theorem in the form:
AC^2 = AB^2 + BC^2
Substituting the given lengths, we get:
13² = 5² + BC²
Solving for BC, we get:
BC = √(13² - 5²)
= √(144 - 25)
= √(119)
= approximately 10.928
Therefore, the length of side BC is approximately 10.928.
