Mathematics

Sloan [31]3 years ago

Answer:

189 students

Step-by-step explanation:

  1. 2/9 = 6th grade
  2. 2/9 = 42 students
  3. So therefore, 2/9 = 42/x
  4. Let's break down the equation above. The original fraction is 2/9. The numerator represents the 6th grade students, and the denominator represents the total number of students in the school. So, if we expand that to actual numbers in the school, it would be 42 over the total number of students in the school (represented by x).
  5. Let's solve it now in the steps below
  6. Write out the equation: \frac{2}{9} = \frac{42}{x}  
  7. Cross multiply, then divide: 9 × 42 = 378, 378 ÷ 2 = 189
  8. So, the total students in the school are 189 students.

I hope this helps!

What is the length of the missing base of the trapezoid?
Eddi Din [679]

Answer:

6 inches

Step-by-step explanation:

Area = (base1 + base2)/2 · height

base1 = b

base2= 8

height = 3

Area = 21

21 = (b+8)/2 ·3

21 = 3(b+8)/2

multiply both sides by 2

42 = 3(b+8)

divide both sides by 3

14 = b+8

subtract 8 from both sides

b = 6 in

Jake has two pet guinea pigs named fluffy and scruffy. Fluffy is8 1/8 inches long. Scruffy is 10 1/4 inches long. How much longe
miss Akunina [59]

Answer:

Scruffy is 2\frac{1}{8} inches longer than Fluffy.

Step-by-step explanation:

Length of Scruffy = 10\frac{1}{4} inches

Length of Fluffy = 8\frac{1}{8} inches

We have to calculate how much Scruffy is longer than Fluffy.

Difference of their lengths = 10\frac{1}{4}-8\frac{1}{8}

                                            = (10 - 8) + (\frac{1}{4}-\frac{1}{8})

                                            = 2 + (\frac{2-1}{8})

                                            = 2 + \frac{1}{8}

                                            = 2\frac{1}{8} inches

Therefore, Scruffy is 2\frac{1}{8} inches longer than Fluffy.
