90+52= 142
180-142= 38
Answer:
38
Step-by-step explanation:
all the angles that add up to 180. so you have a 90 degree angle and a 52 degree angle. if you add 90 + 52 you get 142. if you subtract 142 from 180 you end up with 38. so angle R is 38 degrees

In the school chorus, 3 9 of the students are fourth graders. In simplest form, what fraction of the students in the school chorus are fourth graders?
Answers
Answer: 1 / 3
Step-by-step explanation:
3/9 of the students in the school choir are fourth graders.
To take a fraction to its simplest form, divide both of the numbers in the fraction by their highest common factor.
3 factors = 1 , 3
9 factors = 1, 3 , 9
Highest common factor = 3
Divide both numbers by 3

what percent is 52.8 of 55? also how did u get itttt
Answers
Answer:
The answer is 96%.
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 55 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 55, so we can write it down as 100%=55.
4. We know, that x% equals 52.8 of the output value, so we can write it down as x%=52.8.
5. Now we have two simple equations:
1) 100%=55
2) x%=52.8
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=55/52.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 52.8 is what percent of 55
100%/x%=55/52.8
(100/x)*x=(55/52.8)*x - we multiply both sides of the equation by x
100=1.0416666666667*x - we divide both sides of the equation by (1.0416666666667) to get x
100/1.0416666666667=x
96=x
x=96
now we have:
52.8 is 96% of 55

You would add 1 to each side to make the p alone
-2 =p - 1

-1 = p
To check, you can put p in the original equation
-2 = -1 - 1
-2 = -2 which means this is correct

Answer:
A. d = 0 -- one (1) solution
B. x = {1, 3.5}
Step-by-step explanation:
A. The discriminant for ax²+bx+c = 0 is ...
d = b² -4ac
For the given equation, this is ...
d = (-36)² -4(9)(36) = 0
The discriminant is zero (0).
The discriminant divided by the leading coefficient (a=2) will give the difference between the two roots of the equation. When the difference is zero, as here, both roots are the same. Effectively, there is one (1) solution to the equation.
__
B. The equation can be factored as ...
2x² -9x +7 = (2x -7)(x -1) = 0
The solutions are the values of x that make the factors be zero:
2x -7 = 0 ⇒ x = 7/2
x -1 = 0 ⇒ x = 1
The solutions are x = 7/2 or x = 1.
A book sold 36,600 copies in its first month of release. Suppose this represents 7.1% of the number of copies sold to date. How many copies have been sold to date?
Answers
Answer:
515,493 copies sold
Step-by-step explanation:
Since this is a ratio problem and we have three values and one variable that we need to find (copies sold to date) then we can use the Rule of three to solve this problem. We simply need to multiply the diagonal values and divide by the third value to get the variable. This can be seen below...
36,600 copies <=====> 7.1%
x copies <========> 100%
(36,600 * 100) / 7.1 = 515,492.96
Since the number of books cannot be a decimal we must round up to the nearest book sold, which would mean that the number of copies sold to date is 515,493 copies sold
Saffron is very expensive spice. A shop selling saffron for $ 7.35 per gram.
Write the formula for the cost (y), in dollars, of g grams of saffron.*
a) y = 7.35g
b)g=7.35 y
c) y = 7.35+g
Answers
Answer:
A
Step-by-step explanation:
B is wrong because it's saying to multiply the cost by $7.35.
C is wrong because it's telling you to add the amount of grams to $7.35.
A is the correct answer because you have to mutiply the cost by the grams which is what a number by a variable means.
