Answer:

317.21 (sales price)

259.53 (discount amount)

Step-by-step explanation:

First, we need to divide.

576.75/100=5.7675 (note that I will be rounding at the end)

5.7675 x 55 (100-45) = 317.2125

Rounds to: 317.21

Now, we need to find the discount amount.

 576.75

-317.21

=259.53

Answer: 30°

Step-by-step explanation:

we have to find the angle adjacent with the right angle. For this we use the (-).

At this point, I am guessing you know how to use SOH-CAH-TOA, for this one we use SOH so sin. If you have a calculator set it on degree mode, then plug it in as sin⁻₁(), we put it like that because the missing angle has the given number opposite and the hypotenuse. It solves it and now we get 30 for the answer. I dont know if that made sense, tell me if it didnt so I can explain it better.

Answer:

78%

Step-by-step explanation:

85 × 6 = 510

85 + 78 + 92 + 84 + 93 = 432

510 - 432 = 78

Check

85 + 78 + 92 + 84 + 93 + 78 = 510

510 ÷ 6 = 85

Answer:

  77/85

Step-by-step explanation:

Given:

  cos(A) = 4/5

  sin(B) = 15/17

Find:

  cos(A-B)

Solution:

From your knowledge of Pythagorean triples, you know that one of them is (3, 4, 5) and another is (8, 15, 17). Using your imagination, or by drawing the triangles, you can determine the needed trig functions to be ...

  sin(A) = 3/5

  cos(B) = 8/17

__

Alternatively, you can use the Pythagorean identity to find ...

  sin(A) = √(1 -cos²(A)) = √(1 -(4/5)²) = √(9/25) = 3/5

  cos(B) = √(1 -sin²(B)) = √(1 -(15/17)²) = √(64/289) = 8/17

__

Then application of the angle difference formula is straightforward.

  cos(A -B) = cos(A)cos(B) +sin(A)sin(B)

  cos(A -B) = (4/5)(8/17) +(3/5)(15/17) = (32 +45)/85

  cos(A -B) = 77/85

_____

Some graphing calculators can express the result ...

  cos(arccos(4/5) -arcsin(15/17)) ≈ 0.90588235294

  ... as the fraction 77/85

Answer:

girls 57/100 57% 0.57

Step-by-step explanation:

boys 43/100 43% 0.43

all the ways

The portion of girls in the fourth grade class will be 57/ 100 and in the decimal form it will be 0.057.

It is given that there are total 100 students at a school in fourth grade out of which 57 are girls.

We have to find out the portion of girls in the fourth grade class and express it to decimal.

What is the decimal fractions ?

Decimal fractions are the fractions in which the denominator must be 10 or a multiple of 10 i.e., 100, 1000, 10000, and so on.

As per the question ;

57 are girls out of total 100 students in a class at a school.

The number of boys will be ;

= 100 - 57 = 43

The no. of girls in fraction form will be ;

= 57 / 100

and in the decimal form it will be ;

= 0.057

The no. of boys in decimal form will be ;

= 47 / 100

= 0.047

Thus , the portion of girls in the fourth grade class will be 57/ 100 and in the decimal form it will be 0.057.
