At Bayside High School, 55% of the student body are boys. Thirty-five percent of the boys are on honor roll, and 40% of girls are on honor roll. What percent of the student body is on honor roll? Round to the nearest percent

Answers

Answer 1

Answer: If 55% of the student body are boys, then 45% are girls.

35% of boys are on the honor roll, so 35% of 55% are on the honor roll.

40% of girls are on the honor roll, so 40% of 45% are on the honor roll.

So now we need to find each of those numbers...

35% of 55% =
.35 * .55 = .1925 multiply by 100 to convert to percent

19.25% of boys (in the student body) are on honor roll

40% of 45% =
.40 * .45 = .18 multiply by 100 to convert to percentage

18% of girls (in the student body) are on honor roll

Add the two together to get the total percentage of student body that is on the honor roll...

19.25% + 18% = 37.25%

Round to the nearest percent

37%

Answer 2

Answer: So,

35% of 55% is equal to the percent of boys on honor roll in the student body.

100 - 55 = 45%, which is the percent of girls in the student body.

40% of 45% is equal to the percent of girls on honor roll in the student body.

35% * 55% = 19.25%

40% * 45% = 18%

Adding them up, we get:
19.25 + 18 = 37.25%

Round it to the nearest percent.
37.25 --> 37%

Rounded to the nearest percent, 37% of the student body is on honor roll.

What percent of 40.4 is 50.5

Answers

The solution of expression is, 125%

We have to given that,

To find what percent of 40.4 is 50.5.

Let us take,

x percent of 40.4 is 50.5.

Hence, We can write as,

x% of 40.4= 50.5

x/100 × 40.4 = 50.5

40.4x = 5050

x = 5050 / 40.4

x = 125

Therefore, The solution of expression is, 125%

Ship Co. produces storage crates that require 1.2 meters of material at $.85 per meter and 01 direct labor hours at $15.00 per hour Overhead is applied at the rate of $9 per direct labor hour What is the total standard cost for one unit of product that would appear on a standard cost card?

Answers

Answer:

$3.42

Step-by-step explanation:

Meters of material required = 1.2 meters

Cost per meter of material = $0.85

Direct labor hours = 0.1

Cost of direct labor per hour = $15

Overhead rate = $9 per direct labor hour

Standard cost per unit of product :

(Direct material cost per unit + direct labor cost per unit + overhead cost per unit)

Direct material cost per unit :

Material needed × cost per meter = (1.2 × $0.85) = $1.02

Direct labor cost per unit :

Direct labor hour × cost per hour = ( 0.1 × $15) = $1.5

Overhead cost:

0.1 * $9 = $0.9

Standard cost :

($1.02 + $1.5 + $0.9) = $3.42

How is the divisibility rule for 7 more complicated then the rules for 2,3,5 and 10?

Answers

Divisibility rule of 2: All even numbers are divisible by 2 means no remainder will be left. For example- 4,6,10,18,26 etc

Divisibility rule of 3: A number is divisible by 3 if the sum of the digits is divisible by 3. For example- 15,54,213,699 etc

Divisibility rule of 5: A number is divisible by 5 if the number's last digit is either 0 or 5. For example- 40,85,255,3600,6510 etc

Divisibility rule of 10: The last digit must be zero. For example-100,450,2500,3010,5860 etc

Divisibility rule of 7: To know if a given number is divisible by 7, we will take the last digit of the number and double it. Then we will subtract the result from the rest of the number. If the resulting number is evenly divisible by 7, then the original number is also divisible by 7. For example: 2555, 5509,203, 287 etc

Lets check for 2555. double the last digit. 5 is doubled to 10. Then subtract 10 from 255 this gives 245. 245 is divisible by 7, so 2555 is divisible by 7.

this is the reason, divisibility rule of 7 is complicated as compared to other given number.

Write the quadratic equation in general form and then choose the value of "b."(2x - 1)(x + 6) = 0

Answers

first of all to transfer (2x - 1)(x + 6) = 0 into a form where we can plug it into the quadratic formula we need to use the FOIL method.

(2x - 1)(x + 6) = 0
becomes
2x*x+2x*6+-1*x+-1*6
which simplifies to
2x^2 + 12x - x - 6
and then we add like terms to get
2x^2 + 11x - 6

now that it is in the correct form we can identify "a" "b" and "c" by following this form
ax^2 + bx + c
looking back at the equation we got earlier
2x^2 + 11x - 6

a=2,b=11,and c=-6

Answer:

The answer is b=11
