The straight-line distance after walking 9 blocks east and 5 blocks north can be calculated using the Pythagorean theorem, resulting in a distance of approximately 10.3 blocks, which is shorter than the total 14 blocks walked.

The question involves finding the straight-line distance between two points in a two-dimensional city grid.

When walking 9 blocks east and then 5 blocks north, you are creating a right-angled triangle where the straight-line distance is the hypotenuse of the triangle.

To calculate this, we can use the Pythagorean theorem.

To find the straight-line distance, you square the number of blocks walked east (9 blocks squared) and north (5 blocks squared), and then find the square root of their sum:
Hypotenuse = √((9 blocks)² + (5 blocks)²).
This results in a straight-line path of √(81 + 25) = √106, which is approximately 10.3 blocks.

Hence, even though you walked 14 blocks, the straight-line path is only about 10.3 blocks long, which is considerably shorter than the path you walked.

The point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

We have the point (-1, 6) and the slope m = -3. Substitute:

[tex]y-6=-3(x-(-1))\\\\\boxed{y-6=-3(x+1)}\to\boxed{B)}[/tex]

Answer:

the boat was sold for $17,250

Step-by-step explanation:

Jimmy made a 15% profit, that means that  the 15% of the cost is going to be his profit, so the 15% of $15,000 is:

$15,000(0.15)= $2,250

If his profit is 2,250, the price of the boat is going to be the initial cost plus the profit. So:

Price=$15,000 + $2,250 = $ 17,250

Then, the boat was sold for $17,250

Using proportions and the profit concept, it is found that the boat sold for $17,250.

The rule of three is:

$15,000 - 1

$x - 1.15

Applying cross multiplication:

[tex]x = 15000(1.15) = 17250[/tex]

The boat sold for $17,250.

A total of 41 barrels can be completely filled with 1,250 gallons of water, leaving 20 gallons of water leftover in the tank.

Suppose a water tank contains 1,250 gallons of water and this water is used to fill 30-gallon barrels. In that case, we can calculate the number of barrels that can be completely filled and the remaining water by dividing the total water volume by the volume of one barrel.

First, divide 1,250 gallons by 30 gallons per barrel:

[tex]\frac{1250}{30}[/tex] = 41.66

This division gives us 41 complete barrels, with a remainder indicating that 20 gallons of water will be left.

Therefore, 41 barrels can be completely filled, and 20 gallons of water will remain in the tank.

A better estimate for the length of an ironing board would be 120 inches, or 10 feet. This exercise illustrates the importance of carefully calculated approximations rather than relying on rough 'guesstimates'.

A better estimate for the length of an ironing board would be 120 inches, or 10 feet. This estimate is closer to the final approximate value mentioned in the discussion. However, the early estimate of 3 inches was significantly off. This exercise illustrates the importance of carefully calculated approximations rather than relying on rough 'guesstimates'.

To estimate the value of 98.5*13, you round 98.5 to 100 and 13 to 10, and then multiply to get an estimated product of 1000, which is a simple calculation that provides a close approximation to the precise answer of 1,280.5.

To estimate the value of 98.5*13, you can round 98.5 to the nearest ten and 13 to the nearest ten. So, 98.5 is approximately 100 and 13 is approximately 10. To estimate the product, you multiply these two numbers:

100 * 10 = 1000

The estimated value of 98.5*13 is therefore around 1000. The calculator gives 1,280.5 as the precise answer, but our estimate simplifies the calculation while providing a close approximation.

The number of pots required to plant 24 seeds will be 8.

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that Anna buys 24 seeds and plants 3 in each pot. She has 5 pots.

The number of the pots will be calculated as Anna needs 3 more pots. 3 times 5 is 15 seeds. And she has 24 seeds. so 24 divided by 3 is 8. 8 minus 5 is 3.

Number = 24 / 3 = 8 pots

Therefore, the number of pots required to plant 24 seeds will be 8.

Answer:

B. l = -0.15t + 80

Step-by-step explanation:

From the options we can see that the relation between the battery level (I) and the time elapsed (t) is modeled by the equation of a line, that is:

I = a*t + b

where a and b are some constants, I is in % and t is in minutes.

At t = 0 (when Wally starts to play) the battery is 80%, that is:

80 = a*0 + b

80 = b

At t = 40 minutes the battery is 74%, then:

74 = a*40 + 80

74 - 80 = a*40

-6 = a*40

-6/40 = a

-0.15 = a

Then, the equation is I = -0.15*t + 80
