To find the time it takes to empty the cistern, we first need its total volume. The radius is half the diameter, so r=10/2=5 feetr = 10 / 2 = 5\text{ feet}. The formula for the volume of a cylinder is V=π×r2×hV = \pi \times r^2 \times h. Plugging in our values: V=3.14×52×6=3.14×25×6=3.14×150=471 cubic feetV = 3.14 \times 5^2 \times 6 = 3.14 \times 25 \times 6 = 3.14 \times 150 = 471\text{ cubic feet}. The pump removes 31.4 cubic feet31.4\text{ cubic feet} of water each minute. Dividing the total volume by the rate gives the time: 471/31.4=15 minutes471 / 31.4 = 15\text{ minutes}.

A military training field is rectangular, measuring 160160 yards wide and 300300 yards long. A recruit must travel from one corner of the field to the opposite corner. If the recruit runs directly across the diagonal instead of moving along the outer edges of the two sides, how many yards does the recruit save?

Cevabı ve açıklamayı göster

Cevap: 120

Cevap

120 yards
The route along the edges is the sum of the width and length (160+300=460160 + 300 = 460 yards). The diagonal route is the hypotenuse of the right triangle formed by these sides, calculated as 1602+3002=340\sqrt{160^2 + 300^2} = 340 yards. The distance saved is 460−340=120460 - 340 = 120 yards.

Adım Adım Çözüm

1
Calculate the total distance if traveling along the two outer edges of the rectangular field.
160+300=460160 + 300 = 460 yards.
This establishes the longer route distance to compare against the diagonal shortcut.
2
Set up the Pythagorean theorem to find the length of the diagonal route.
1602+3002=c2160^2 + 300^2 = c^2
The rectangular field forms a right triangle where the width and length are the legs, and the diagonal is the hypotenuse.
3
Solve for the diagonal length (cc).
c=115600=340c = \sqrt{115600} = 340 yards.
This gives the exact distance of the direct route.
4
Calculate the difference between the two routes.

A surveyor is mapping a plot of land and launches a drone from a perfectly flat field. The drone ascends vertically to an altitude of 3030 meters. It then travels horizontally in a straight line for 1616 meters to photograph a landmark. What is the direct line-of-sight distance, in meters, from the launch point on the ground to the drone?

Cevabı ve açıklamayı göster

Cevap: 34

Cevap

The direct line-of-sight distance is 3434 meters.
The drone's flight path forms a right-angled triangle relative to the starting point. By applying the Pythagorean theorem (a2+b2=c2a^2 + b^2 = c^2), we square the vertical distance (302=90030^2 = 900) and the horizontal distance (162=25616^2 = 256). Adding these values yields 11561156. Taking the square root of 11561156 gives the direct line-of-sight distance, which is 3434 meters.

Adım Adım Çözüm

1
Model the drone's flight path as a right-angled triangle.
The vertical ascent forms one leg (a=30a = 30) and the horizontal flight forms the other leg (b=16b = 16). The direct line-of-sight distance is the hypotenuse (cc).
Vertical and horizontal movements are perpendicular, creating a 90∘90^\circ angle.
2
Apply the Pythagorean theorem to calculate the hypotenuse.
a2+b2=c2a^2 + b^2 = c^2 becomes 302+162=c230^2 + 16^2 = c^2.
The Pythagorean theorem relates the lengths of the legs to the length of the hypotenuse in any right triangle.
3
Square the lengths of the two legs and add them together.
900+256=1156900 + 256 = 1156. So, c2=1156c^2 = 1156.
This evaluates the left side of the equation to isolate c2c^2.
4
Take the square root of the sum to find the actual distance.
c=1156=34c = \sqrt{1156} = 34.
Taking the square root of c2c^2 yields the length of the hypotenuse.

60
The correct answer is found by first determining the hypotenuse of the right-triangular lot, which is 100 yards (602+802=100260^2 + 80^2 = 100^2). The total perimeter is 240 yards (60 + 80 + 100). Because the post spacing is given in feet, the perimeter must be converted to 720 feet (240 × 3). Finally, dividing the 720-foot boundary by the 12-foot spacing requirement yields exactly 60 posts.

Adım Adım Çözüm

1
Find the length of the third side of the lot using the Pythagorean theorem (a2+b2=c2a^2 + b^2 = c^2).
602+802=3600+6400=1000060^2 + 80^2 = 3600 + 6400 = 10000. The square root of 1000010000 is 100100 yards.
The boundary of a right-triangular lot includes the hypotenuse, which must be found to calculate the total perimeter.
2
Calculate the total perimeter of the triangular lot.
60+80+100=24060 + 80 + 100 = 240 yards.
The fencing will enclose the entire boundary of the lot.
3
Convert the perimeter into feet to match the unit of the post spacing.
240 yards×3 feet/yard=720 feet240 \text{ yards} \times 3 \text{ feet/yard} = 720 \text{ feet}.
Measurements must be in the same unit (feet) before dividing.
4
Divide the total perimeter by the distance required between each post.
720÷12=60720 \div 12 = 60 posts.
For a closed loop, the total number of posts equals the total perimeter divided by the spacing distance.

The pool's base has an area of 40×25=1,00040 \times 25 = 1,000 square feet. When 1,5001,500 cubic feet of water is removed, the water level drops by 1,500÷1,000=1.51,500 \div 1,000 = 1.5 feet. Subtracting this drop from the initial depth of 88 feet gives a new depth of 6.56.5 feet. Alternatively, finding the original volume (8,0008,000 cubic feet), subtracting the removed water (6,5006,500 cubic feet), and dividing by the area (1,0001,000 square feet) also yields 6.56.5 feet.

Adım Adım Çözüm

1
Calculate the base area of the rectangular pool.
1,0001,000 square feet
The base area is needed to determine how changes in volume affect the depth of the water. Area = length ×\times width = 40×25=1,00040 \times 25 = 1,000.
2
Determine the change in the water depth.
The depth drops by 1.51.5 feet.
Dividing the removed volume by the base area gives the vertical drop in water level. 1,500÷1,000=1.51,500 \div 1,000 = 1.5.
3
Calculate the new depth.
6.56.5 feet
Subtract the drop in water level from the initial depth. 8−1.5=6.58 - 1.5 = 6.5.

The correct answer accurately calculates the diagonal length using the Pythagorean theorem (452+242=c245^2 + 24^2 = c^2, so c=51c = 51 yards) and then converts that distance into feet by multiplying by 3 (51×3=15351 \times 3 = 153 feet).

Adım Adım Çözüm

1
Apply the Pythagorean theorem (a2+b2=c2a^2 + b^2 = c^2) to find the diagonal length of the zip line in yards.
242+452=576+2025=260124^2 + 45^2 = 576 + 2025 = 2601 square yards.
The vertical height and horizontal distance form a right triangle with the zip line acting as the hypotenuse.
2
Calculate the square root of the sum to find the actual length.
2601=51\sqrt{2601} = 51 yards.
This isolates cc (the hypotenuse) to give the actual length of the zip line in yards.
3
Convert the length from yards to feet.
51×3=15351 \times 3 = 153 feet.
The question specifically asks for the length in feet, and there are 33 feet in one yard.
