If 65% of something is 112, what is 100%?

2 answers:

8 0

Do this:
65/100 = 112/x then cross multiply
65x = 11,200, then divide by 65 on both sides of the equation
x = roughly 172.3
So the 100 % = about 172.3

100%-65%=35% you would multiply.35 by 112 which is 42.7 then you would add 42.7 to 112 which is 164.7 and then you would just round it and get 164 and that would be your answer.

Given the Arithmetic series A1+A2+A3+A4

natali 33 [55]

Answer:

$S _{19} = 760$

Step-by-step explanation:

$a1 = 13 \\ a2 = 16 \\ d = a2 - a1 = 16 - 13 = 3 \\ d = 3 \\ a _{n} = l = 67 \\$

now,

$a _{n} = a + (n - 1) \times d \\ 67 = 13 + (n - 1) \times 3 \\ 67 = 13 + 3n - 3 \\ 67 - 13 + 3 = 3n \\ 57 = 3n \\ 3n = 57 \\ \\ n = \frac{57}{3} \\ \\ n = 19$

now the sum of the numbers

$S _{n} = \frac{n}{2} (a + l) \\ \\ S _{19} = \frac{19}{2} (13 + 67) \\ \\ S _{19} = \frac{19}{2} (80) \\ \\ S _{19} = \frac{19}{2} \times 80 \\ \\ S _{19} = 19 \times 40 \\ S _{19} = 760$

A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 100 nails an

ExtremeBDS [4]

Answer:

The system 150x+400y=1950 and x = y+2 could be used to determine the number of small boxes and large boxes ordered where x represents the number of small boxes and y represent the number of large boxes.

Step-by-step explanation:

Given,

Number of nails in small box = 150 nails

Number of nails in large box = 400 nails

Total nails in ordered boxes = 1950 nails

Let,

x be the number of small boxes ordered.

y be the number of large boxes ordered.

According to given statement;

150x+400y=1950 Eqn 1

The contractor bought 2 more small boxes than large boxes

x = y+2 Eqn 2
