Write two different expressions to represent the number that results when x is increased by 40%.

dedylja [7]

Answer:

$x+ 0.4x$

$1.4x$

Step-by-step explanation:

When x is increased by 40%, then we find 40% of x and add it to x.

$x + \frac{40}{100} x$

We can simplify this to get;

$x + \frac{4}{10} x$

This is the same as:

$x + 0.4x$

When we add we obtain:

$1.4x$

R 3.5 Mellom hvilke to hele tall ligger kvadratroten til a) 35 b) 67 c) 93

NikAS [45]

Answer:

a) 5, 6

b) 8, 9

c) 9, 10

Step-by-step explanation:

It is useful to know the squares of small integers:

5² = 25

6² = 36

7² = 49

8² = 64

9² = 81

10² = 100

Then the problem becomes one of identifying the perfect squares the given number lies between

a) 25 < 35 < 36 ⇒ 5 < √35 < 6

b) 64 < 67 < 81 ⇒ 8 < √67 < 9

c) 81 < 93 < 100 ⇒ 9 < √93 < 10
