Write in decimal notation 35 233/1000

1 answer:

6 0

Is that 35 and 233 over 1,000? If so, the 35 remains there since it's a whole number and 233/1,000 isn't greater than 1. 233/1,000 is the same thing as 0.233. That means that all you need to do is add 35 + 0.233.
35 + 0.233 = 35.233.

Calculate the constant of variation if y varies directly as x.

luda_lava [24]

Answer:

Option A is correct.

The constant of variation is, $-\frac{3}{2}$

Step-by-step explanation:

The Direct variation says that:

if a vary directly to b then, the equation is of the form: a = kb where k is the constant of variation.

Given: if y varies directly as x.

By definition of direct Variation:

y = kx where is the constant of variation.

It is also given that: y = -3 and x =2

Solve for k;

-3 = 2k

Divide both sides by 2 we have;

$k = -\frac{3}{2}$

Therefore, the constant of variation is, $-\frac{3}{2}$

Cho is driving a car. He gets to his destination, which is 72 miles away, in 1 hour and 30 minutes. a. The equation d = rt can b

Kay [80]

Answer:

50 miles per hour

Step-by-step explanation:

In this question, we are asked to substitute the information given into the equation. First we need consistency on units. Hence the 1hr 30 minutes is same as 1.5hrs

Now since d =rt

We need to get r = d/t

This means r = 75/1.5 = 50 miles per hour

*At first a price was decreased by 12%, then it was discounted again by an additional 5%. What is the percent of the total disco

ratelena [41]

The percent of total discount is 16.4 %

Solution:

Given that,

At first a price was decreased by 12%, then it was discounted again by an additional 5 %

To find: Percent of total discount

Let "x" be the original price

At first a price was decreased by 12%

Therefore,

Discounted price = original price - 12 % of original price

Discounted price = x - 12 % of x

$Discounted\ price = x - \frac{12}{100} \times x\\\\Discounted\ price = x - 0.12x\\\\Discounted\ price = 0.88x$

It was discounted again by an additional 5%

Therefore,

Discounted price = 0.88x - 5 % of 0.88x

$Discounted\ price = 0.88x - \frac{5}{100} \times 0.88x\\\\Discounted\ price = 0.88x - 0.05 \times 0.88x\\\\Discounted\ price = 0.88x - 0.044x\\\\Discounted\ price = 0.836$

Thus the percent of total discount is:

$Percent = 100 \% - 0.836 \times 100 \%\\\\Percent = 100 \% - 83.6 \%\\\\Percent = 16.4 \%$

Thus the percent of total discount is 16.4 %
