Round off 54.3223 to 1 decimal place

Answers

Answer:

54.3

Step-by-step explanation:

since it is mentioned 54.3223, then u should see the two decimal places as they are asking to round it off to one decimal place. so we should see 54.32 only

if the second decimal is less than 5, then you should write the first decimal as it is like the above mentioned question (remember we are only supposed to mention one decimal place)

but if it is 5 or more, then you should move the first decimal to the next number. for example, 54.678. for this you should write 54.7 because the second decimal is more than 5

if they are asking to round it off to 3 places then you should see 4 decimal places

с

13.5 cm
A
B

Answers

Answer:

AB ≈ 8.86 cm

Step-by-step explanation:

Using the sine ratio in the right triangle

sin41° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{13.5}[/tex] ( multiply both sides by 13.5 )

13.5 × sin41° = AB , then

AB ≈ 8,86 cm ( to 3 significant figures )

Answer:

8.87

Step-by-step explanation:

use the sin law for right triagles sin(θ)= opposite/hypotenuse so

sin(41)=(AB)/13.5

13.5×sin(41)=AB

8.87=AB

Original Price $69.80 Percent of Discount 60% Sale Price = ?

Answers

Answer:

$27.92

Step-by-step explanation:

To find the sale price, multiply the original price by 0.4:

69.8(0.4)

= 27.92

So, the sale price is $27.92

The amount for sale is $27.92.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Original Price = $69.80

And, Percent of Discount = 60%

Hence, Sale price is find as;

Sale price = $69.80 - 60% of 69.80

                = $69.8 - 60/100 × 69.80

                = $69.80 - $41.88

                = $27.92

inches long. At the same time, ber teddy bear casts a
shadow that is eight inches long. How tall is the teddy
bear?

Answers

Answer:

20

Step-by-step explanation:

30:12 is the original ratio. So if you divide both sides by the numbers' GCF of 6 you'll get a simplified ratio of 5:2. Then multiply both sides by 4 to keep the ratio constant, then you'd get 20:8. So when the teddy bear casts a shadow of 8 inches long the actual teddy bear is 20 inches tall. Hope this helps!

water flows through a pipe at a rate of 7 cubic meters per month. Express this rate of flow in gallons per minute. Round your answer to the nearest hundredth.

Answers

Answer:

0.04

Step-by-step explanation:

The rate of flow is 0.043 gallons per minute.

How to convert litres to gallons ?

Divide by 0.264 to obtain litres from gallons and multiply by 0.264 to obtain in gallons from litres.

According to the given question

Water flows through a pipe at a rate of 7 cubic meters per month.

We know 1 cubic meter is = 1000 litre

∴ 7 cubic meters per is

= (7 × 1000) litre

= 7000 litre

= (7000 × 0.264) gallons

= 1848 gallons per month

Now 1 month is

= ( 1 × 30 × 24 × 60 ) minutes.

=43200 minutes

So in 43200 minutes 1848 gallons of water flows through that pipe

∴ In a unit minute or per minute it the rate of flow will be

= 1848/43200 gallons per minute

= 0.043 gallons per minute.

Answers

Answer:

A. x = -3

B. x = 2

C. x = 9/10

Step-by-step explanation:

(A) –12x + 9 = –15x

Collect like terms

9 = -15x + 12x

9 = -3x

x = 9 / -3

x = -3

(B) 4.5x + 11.5 = 8.5x + 3.5

4.5x - 8.5x = 3.5 - 11.5

-4x = -8

x = -8 / -4

x = 2

(C) 23x – 9 = 13x

-9 = 13x - 23x

-9 = -10x

x = -9 / -10

x = 9/10
