Answer:
x + 90 + 63 = 180
Step-by-step explanation:
∠A + ∠B + 45 + 63 = 180 {Straight line angles}
From the figure we know that , ∠B + 45 = 90
Therefore, ∠A + 90 + 63 = 180
Answer:
Option B is correct.
Step-by-step explanation:
∠A = 27
27 + 90 + 63 = 180
you can see that square right. the square is 90.

A Businessman exchange Nepali currency rupees 660000 INR to US Dollar at the rate of Dollar 1 is equal to INR rupees 110 after 4 days Nepali currency is revaluated by 10% and he has changed the dollars INR to Nepali currency again what is his gain or loss find it
Answers
Answer:
Gain = $666.67
Step-by-step explanation:
The businessman exchanged 660000 INR to US Dollar using the exchange rate of $1 = INR 110
Value of the money in dollars is;
(660000 × 1)/110 = $6000
Now, Nepali currency is reevaluated by 10%. This means it's value has gone up by 10%.
Thus, exchange rate of $1 is now;
110 - 10%(110) = INR 99
Thus, 660000 INR to US Dollar using this new exchange rate gives;
(660000 × 1)/99 = $6666.67
Therefore he made a gain.
Gain = 6666.67 - 6000
Gain = $666.67

Step-by-step explanation:
To solve a system of equations, solve one or both of the equations for the same variable. Then multiply one of the equations such that the coefficients of one variable are the additive inverse of the variable in the other equation. After doing so, add the two equations, then solve for the other variable using inverse operations. Finally, substitute the value of the other variable into one of the original equations in the system and solve for the unknown variable.
2x + y = 3
y = x - 2
First, manipulate the first equation such that the equation is solved for (y), this can be done using inverse operations,
y = 3 - 2x
y = x - 2
Now multiply the second equation by (2) so that the (x) coefficients are additive inverses of each other,
y = 3 - 2x
2y = 2x - 4
Add the equations,
3y = -1
Inverse operations,
3y = -1
/3 /3
y = [tex]-\frac{1}{3}[/tex]
Now back solve, substitute the value of (y) into the equation and solve for (x),
[tex]y=x-3\\[/tex]
Substitute,
[tex](-\frac{1}{3})=x-3[/tex]

Solve. Suppose that 1,000 students took a math examination wherein the maximum score that they can obtain is 100. Their average score is 70 with a standard of the deviation of 5. How many of the students obtained a score from 70 to 95?
Answers
Answer:
prolly like 689
Step-by-step explanation:
As per the given data, approximately 499 of the 1,000 students obtained a score from 70 to 95.
What is z-score?A standardized score is an example of a z-score. A z-score is a measure of how far a data point is from the mean in a distribution.
To solve this problem, we need to calculate the number of students who obtained a score from 70 to 95.
First, we need to calculate the z-scores for these two scores using the formula:
z = (score - mean) / standard deviation
For a score of 70:
z = (70 - 70) / 5 = 0
For a score of 95:
z = (95 - 70) / 5 = 5
Next, we need to find the area under the standard normal distribution curve between these two z-scores using a standard normal distribution table or calculator.
The area between z = 0 and z = 5 is approximately 0.499, or 49.9%.
Finally, we can calculate the number of students who obtained a score from 70 to 95 by multiplying this proportion by the total number of students:
Number of students = proportion x total number of students
Number of students = 0.499 x 1000
Number of students ≈ 499
Therefore, approximately 499 of the 1,000 students obtained a score from 70 to 95.

Beth says 20-5x3 is 45, pat says 20-5x3 is 5. who is right?
Answers
Answer:
Pat is right
Step-by-step explanation:
first multiply/divide then add/subtract,
Beth: 20 - 15 = 45 => 5 ≠ 45
Pat: 20 - 15 = 5 => 5 = 5
Answer:
Pat
Step-by-step explanation:
There is only one correct answer. To find it, you must follow the correct order of operations.
There is a subtraction and a multiplication. There are no parentheses.
The rule is that you must do the multiplication before the subtraction.
20 - 5 * 3 =
= 20 - 15
= 5
In order to get Beth's answer, you'd have to do the subtraction first. If there were parentheses like this: (20 - 5) * 3, then you'd do the subtraction first getting 15 * 3 which is 45, but the problem has no parentheses, so the correct answer is 5.
The correct answer is 5, and Pat is correct.

In the triangle above, the measure of A is 66°, and the measure of B is 68°. What is the measure of C?
Answers
Answer:
46°
Step-by-step explanation:
Given that :
Angle, A = 66°
Angle B = 68°
The sum of angles in a triangle is given by :
A + B + C = 180° (sum if angles una triangle)
66° + 68° + C = 180°
134° + C = 180°
C = 180° - 134°
C = 46°
Hence, angle C is 46°

The Peak Library Book Club was doing a bake sale. Their goal was $550 for the entire week. The sale has lasted 4 days so far and each day they raised about $135.50. Will they make their goal by day 4? If not, how much do they need on day 5 to meet it?
Answers
Answer: See explanation
Step-by-step explanation:
Since their goal was $550 for the entire week and the sale has lasted 4 days already and each day they raised about $135.50, the amount raised for the 4 days will be:
= $135.50 × 4
= $542.00
No, they won't make their goal by the 4th day.
The amount needed on the 5th day will be:
= $550 - $542
= $8
They'll need $8 on the 5th day.
