Mrs. Hart spent 3/5 of her money on a bag and 1/6 on a belt. She had $14 left. How much money did she have initially?

klasskru [66]

Answer:

$60

Step-by-step explanation:

Let x represent the initial money she had

She spent 3/5 of her money on a bag, That is;

3/5 of x

= 3/5 * x

and 1/6 of x on a belt

Therefore, the total money she spent is

3/5 * x + 1/6 * x

She had $14 left after all her purchases

To find how much she had left, sum up all her spending and what she has left

3/5 * x + 1/6 * x + 14 = x

collect like terms

3/5 x + 1/6 x - x = -14

23/30 x -x = -14

-7/30x = -14

x = $60

In a race Brian Collins has to cross 10 hurdles. Find the probability that he jumps a hurdle is 2/3. Find p(knocks down all hurd

Natalija [7]

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

Probability that he jumps a hurdle = $\frac{2}{3}$

Total number of hurdles = 10

Probability that he knocks down = $1-\frac{2}{3}=\frac{1}{3}$

So, Probability (knocks down all hurdles ) is given by

$(\dfrac{1}{3})^{10}\\\\=\dfrac{1}{59049}$

Hence, Option 'a' is correct.

Help asap I will give u huge amount of brainly points

Minchanka [31]

Answer:

$\boxed{\sf -\dfrac{5}{8}}$

Use BODMAS rule,

where:

brackets
order
division
multiplication
addition
subtraction

Given expression:

$\rightarrow \sf -\dfrac{1}{5} \times [\:4-14\times\left(\dfrac{1}{4} \right)^2]$

simplify exponent

$\rightarrow \sf -\dfrac{1}{5} \times [\:4-14\times\left(\dfrac{1}{16} \right)]$

$\rightarrow \sf -\dfrac{1}{5} \times [\:4-\(\dfrac{14}{16}]$

$\rightarrow \sf -\dfrac{1}{5} \times [\:4-\(\dfrac{7}{8}]$

$\rightarrow \sf -\dfrac{1}{5} \times [\:\dfrac{32}{8} -\(\dfrac{7}{8}]$

$\rightarrow \sf -\dfrac{1}{5} \times [\:\dfrac{25}{8}]$

multiply fractions

$\rightarrow \sf -\dfrac{25}{40}$

$\rightarrow \sf -\dfrac{5}{8}$
