Answer:

80,000,000

Step-by-step explanation:

The difference between 10,000,000 and 50,000,000 is 40,000,000 per hectare. The question states two hectares, so 40,000,000 x 2 is 80,000,000.

Hope that helps.

Lashonda sells beaded necklaces. Each large necklace sells for $5.30 and each small necklace sells for $4.50. How much will she

Tasya [4]

Answer:

$ 37.10 for the large necklaces sold

$ 17.20 for the small necklaces sold

$ 54.30 for the total necklaces sold

Step-by-step explanation:

For each large necklace it costs $5.30 so multiply $5.30 x 7= $37.10 because that's how many she sold. For each small necklace it costs $4.30 so multiply $4.30 x 4= $17.20 because that's how many she sold. If you want the total cost of all the necklaces sold you have to add the two prices together. Please give me the brainliest answer?

Lucy weighed an object on her balance and recorded amass of 36.5 grams . the weight on the label says it should . weigh 36.8 gra

Lunna [17]

Error in the weight is 0.3g (Difference between the actual 36.8g and the experimented 36.5g)
So %Error = Error/Correct value *100%
= 0.3/36.8 *100 =0.815% = 0.82% (2 significant figure)

PROBLEM: Riley has a rectangular shaped patio that is 13 feet long by 15 feet wide. He wants to DOUBLE THE AREA of the patio by

photoshop1234 [79]

Answer:

1) The equation that represents the total area of Riley's proposed ratio is $A' = (\sqrt{2}\cdot x)\cdot (\sqrt{2}\cdot y)$ .

2) The length and width of the new patio are approximately 18.4 feet and 21.2 feet, respectively.

Step-by-step explanation:

1) From Geometry we remember that area formula for the rectangle is represented by:

$A = x\cdot y$ (1)

Where:

$A$ - Area, measured in square feet.

$x$ - Length, measured in feet.

$y$ - Width, measured in feet.

From statement we know that Riley wants to double the area, that is:

$A' = 2\cdot A$ (2)

By applying (1) in (2), we get the following expression:

$A' = 2\cdot x\cdot y$ (3)

Given that Riley wants to double the area of the pation by increasing the length and width by the same amount, we can rearrange (3) by algebraic means:

$A' = \sqrt{2}\cdot \sqrt{2}\cdot x\cdot y$
