Write an equation and solve round to the nearest hundredth when necessary 19 is what percent of 40

Mathematics
1 answer:
german3 years ago
4 0

Answer:

Final answer is 47.5%.

Step-by-step explanation:

Let the missing percent is x.

Then x percent of 40 can be written as: 40\cdot\frac{x}{100}.

Given that resulting percent value is 19.

So we can set both equal.

40\cdot\frac{x}{100}=19

40x=19\cdot100

40x=1900

x=\frac{1900}{40}

x=47.5

So the final answer is 47.5%.

Pani-rosa [81]

Given:

The inequality is

x+19\leq 23

To find:

The value of x and then graph on the number line.

Solution:

We have,

x+19\leq 23

Subtracting 19 from both sides, we get

x+19-19\leq 23-19

x\leq 4

It means all the real values of x which are less than or equal to 4 are in the solution set. So, an arrow approaches towards left from x=4 as shown in the below figure.

Use the multiplier method to decrease £27 by 8%. You must show your working.
Nitella [24]

Answer:

decrease by 2.16

Step-by-step explanation:

Convert the problem to an equation using the percentage formula: P% * X = Y.

P is 10%, X is 150, so the equation is 10% * 150 = Y.

Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.

katen-ka-za [31]

The total length of red and blue ribbons is 10.2 m.

Given that, the length of the red ribbon =2.4 m and the length of the blue ribbon =7.8 m.

<h3>How to add two decimals?</h3>

Adding decimals is similar to the usual addition of whole numbers. We know that a decimal number is a number with a whole number part and a fractional part which is separated by a decimal point.

Now, the length of the red ribbon + the length of the blue ribbon=2.4+7.8

=10.2 m

Therefore, the total length of red and blue ribbons is 10.2 m.
