Answer: 30%

Step-by-step explanation:

Percent error = \dfrac{|\text{Estimated value - Actual value}|}{\text{Actual value}}\times100\%

Estimated number of games win this year = 7

Actual number of games won = 10

Now ,   the percent error of Doug’s estimate = \dfrac{|7-10|}{10}\times100\%= \dfrac{3}{1}\times10\%=30\%

Hence, the percent error of Doug’s estimate = 30%

Answer: the ANSWER IS 11 sqt

Step-by-step explanation:

Factor 1331 into its prime factors

          1331 = 113

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

Factors which will be extracted are :

          121 = 112

Factors which will remain inside the root are :

          11 = 11

To complete the simplification we take the squre root of the factors which are to be extracted. We do this by dividing their exponents by 2 :

          11 = 11

The simplified SQRT looks like this:

        11 • sqrt (11)  

Simplified Root :

11 • sqrt(11)

The length around the outside of semicircle O from point L through point M to point N is 14 centimeters. The perimeter of semici
Luden [163]
The area would be 83.67 cm.

A semicircle is half of a circle.  The perimeter of the semicircle would be half of the perimeter (circumference) of the entire circle.  The formula for circumference is:

C=πd

Using our information, we have  

22.92 = 0.5(3.14)d
22.92 = 1.57d

Divide both sides by 1.57:

22.92/1.57 = 1.57d/1.57
14.6≈d

Since the diameter is 14.6, the radius is 14.6/2 = 7.3.

We use the radius for the area of the semicircle:

A=0.5πr²
=0.5(3.14)(7.3)²
=83.67

Divide 50 into the ratio 1:4
Alex787 [66]
The answer is 10:40 
so 1:4
add it up
1+4=5

so 5 total units
$50=5 units
divide by 5
$10=1 unit

so 1:4=10:10 times 4=10:40

A container holds 44 cups of water. how much is this in gallons
Zepler [3.9K]

Answer:

44 cups = 27.5 gallons

Step-by-step explanation:

Using the conversion:

  • 1 cup = 0.625 gallons

We can find what is 44 cups in gallons.

=> 1 cup = 0.625 gallons

=> 44 x 1 = 0.625 x 44

=> 44 cups = 0.625 x 44 gallons

=> 44 cups = 27.5 gallons

Therefore, 44 cups = 27.5 gallons.

Hoped this helped.
