What does the initial value mean for this function?

1 answer:

5 0

She saves 10 per week.......after 4 weeks, she had 90

so if she started with nothing, after 4 weeks she would have 40.....but for her to have 90, she would have had to have started with (90 - 40) = 50.

Think about it....she starts with 50....and then saves 10 for 4 weeks giving her 40......and now she has 40 + 50 = 90

so ur answer is : Roberta had $ 50 before she started to save money each week

The following masses are given in kilograms. Use metric prefixes on the gram to rewrite them so the numerical value is bigger th

vovangra [49]

Answer:

a) 38 mg

b) 230 Exa-g

c) 24 ng

d) 8 Eg

e) 4.2 g

Step-by-step explanation:

Given:

a) 3.8×10⁻⁵ kg

1 kg = 10⁶ mg

Multiply the above value by 10⁶

we get

3.8×10⁻⁵ × 10⁶ = 38 mg

b) 2.3 × 10¹⁷ kg

2.3 × 10²⁰ g

1 exa = 10¹⁸

multiply by 10⁻¹⁸

we get

230 Exa-g

c) 2.4 × 10⁻¹¹ kg

24 × 10⁻⁹ g

1 g = 10⁹ ng

thus,

24 × 10⁻⁹ g × 10⁹ = 24 ng

d) 8×10¹⁵ kg

8 × 10¹⁸ g

1 exa gram = 10¹⁸ g

( 8 × 10¹⁸ ) × 10⁻¹⁸ = 8 Eg

e) 4.2 × 10⁻³ kg

4.2 × 10⁻³ × 10³ = 4.2 g

What is the value of m in the equation 1/2m -3/4 n=16,when n =8?

maks197457 [2]

Hi,

Equation;

$n = 8 \\ \frac{1}{2} m - \frac{3}{4} n = 16$

Variable n is given so no need to write it down. Instead use 8.

Solving:

$\frac{1}{2} m - \frac{3}{4} 8 = 16 \\ \frac{1}{2} m - 3 \times 2 = 16 \\ \frac{1}{2} m - 6 = 16 \: \: \: | \times 2 \\ m - 12 = 32 \\ m = 32 + 12 \\ \\ m = 44 \: \: \: \: \: \: \: (result)$

Hope this helps.
