3/10 divided by -1/3

Mathematics
1 answer:
Snezhnost [94]3 years ago
8 0

Answer:

-9/10

Step-by-step explanation:

  1. Find the LCM of 10 and 3: 30
  2. Alter the numerators to fit the denominators: 3 × 3 = 9, -1 × 10 = -10
  3. Re-write the fractions: 9/30 ÷ -10/30
  4. 9/30 ÷ -10/30 = 9/30 × -30/10
  5. 9/30 × -30/10 = -270/300
  6. -\frac{270}{300} = -\frac{9}{10}  

I hope this helps!

daser333 [38]

Answer:

-1,512,390

Step-by-step explanation:

Given

a1 = 15

a_i = a_{i-1} -7

Let us generate the first three terms of the sequence

a_2 = a_{2-1}-7\\a_2 = a_1 - 7\\a_2 = 15-7\\a_2 = 8

For a_3

a_3 = a_{3-1}-7\\a_3 = a_2 - 7\\a_3 = 8-7\\a_3 = 1

Hence the first three terms ae 15, 8, 1...

This sequence forms an arithmetic progression with;

first term a = 15

common difference d = 8 - 15 = - -8 = -7

n is the number of terms = 660 (since we are looking for the sum of the first 660 terms)

Using the formula;

S_n = \frac{n}{2}[2a + (n-1)d]\\

Substitute the given values;

S_{660} = \frac{660}{2}[2(15) + (660-1)(-7)]\\S_{660} = 330[30 + (659)(-7)]\\S_{660} = 330[30 -4613]\\S_{660} = 330[-4583]\\S_{660} = -1,512,390

Hence the sum of the first 660 terms of the sequence is  -1,512,390

vladimir1956 [14]

y = -3.7x + 1 when x = -2

Plug in:

y = -3.7(-2) + 1

-3.7(-2) = 7.4

y = 7.4 + 1

7.4 + 1 = 8.4

y = 8.4

Answer - C) 8.4
