A competitive cliff-diver jumps from a height of 75 feet. Find the number of feet the diver is above the ocean in 2 seconds. Evaluate for t=2 by using the formula 75−16t2 , where t is time in seconds. (1 point) $$
To find the number of feet the diver is above the ocean after 2 seconds, we need to substitute t=2 into the formula 75 - 16t^2:
75 - 16(2)^2
First, we evaluate 2 squared:
75 - 16(4)
Next, we multiply 16 by 4:
75 - 64
Finally, we subtract 64 from 75 to find the answer:
11
Therefore, the diver is 11 feet above the ocean after 2 seconds.
82x(-13)
To calculate 82 multiplied by -13, simply multiply the two numbers together:
82 x (-13) = -1066
Therefore, 82 multiplied by -13 equals -1066.
Multiply −116 by 7. Write the answer as a mixed number.
To multiply -116 by 7, simply multiply the two numbers together:
-116 * 7 = -812
The product is -812. To write it as a mixed number, divide the product by the denominator (7) and write the result as the whole number and the remainder as the numerator:
-812 ÷ 7 = -116 remainder 4
Therefore, the answer as a mixed number is -116 4/7.
Multiply −1 1/6 by 7. Write the answer as a mixed number.
To multiply -1 1/6 by 7, we first convert the mixed number to an improper fraction.
-1 1/6 can be written as -7/6.
Now we multiply -7/6 by 7:
-7/6 * 7 = -49/6
To write the answer as a mixed number, we divide the numerator (49) by the denominator (6) and write the result as the whole number. The remainder becomes the numerator of the fractional part.
49 ÷ 6 = 8 remainder 1
Therefore, the answer as a mixed number is -8 1/6.
Of the cars in a used-car lot, 25 are the color gray. 13 of the gray cars are electrically powered vehicles. What fraction of the cars on the lot are both gray and electrically powered? Leave your answer in simplified fraction form.(1 point)
To find the fraction of cars on the lot that are both gray and electrically powered, we need to divide the number of gray and electrically powered cars (13) by the total number of cars on the lot (25).
Therefore, the fraction of cars on the lot that are both gray and electrically powered is 13/25.
Of the cars in a used-car lot, 2/5 are the color gray. 1/3 of the gray cars are electrically powered vehicles. What fraction of the cars on the lot are both gray and electrically powered? Leave your answer in simplified fraction form.(1 point)
To find the fraction of cars on the lot that are both gray and electrically powered, we need to multiply the fraction of gray cars (2/5) by the fraction of gray cars that are electrically powered (1/3).
(2/5) * (1/3) = (2 * 1) / (5 * 3) = 2/15
Therefore, the fraction of cars on the lot that are both gray and electrically powered is 2/15.
Lake Profondo has a depth of 84 feet. Lake Segundo is 56 as deep. What is the elevation at the bottom of Lake Segundo? (Remember, the elevation is below sea level. Account for this in your answer.)(1 point)
To determine the elevation at the bottom of Lake Segundo, we need to subtract the depth of Lake Segundo from the sea level.
Sea level is generally considered to be 0 feet. Since both lakes are below sea level, we need to account for this by subtracting the depths from 0.
Therefore, the elevation at the bottom of Lake Segundo would be: 0 - 56 = -56 feet.
The elevation at the bottom of Lake Segundo is -56 feet, indicating that it is 56 feet below sea level.
Lake Profondo has a depth of 84 feet. Lake Segundo is 5/6 as deep. What is the elevation at the bottom of Lake Segundo? (Remember, the elevation is below sea level. Account for this in your answer.)(1 point)
To determine the depth of Lake Segundo, we can calculate 5/6 of the depth of Lake Profondo.
Depth of Lake Profondo: 84 feet
Depth of Lake Segundo: (5/6) * 84 = (5 * 84) / 6 = 420 / 6 = 70 feet.
Now we need to account for the elevation below sea level. Since both lakes are below sea level, the elevation at the bottom of Lake Segundo would be the negative value of its depth.
Therefore, the elevation at the bottom of Lake Segundo would be: -70 feet.
The elevation at the bottom of Lake Segundo is -70 feet, indicating that it is 70 feet below sea level.
Divide −72 by −4 . Then divide the quotient by −9 . What is the final quotient? (1 point)
To divide -72 by -4, we get:
-72 / -4 = 18
Next, we divide the quotient (18) by -9:
18 / -9 = -2
Therefore, the final quotient is -2.
What is the quotient of 100÷(−10)÷5 ?(1 point) Responses −2 negative 2 −50 negative 50 2 2 −200
To solve the expression 100 ÷ (-10) ÷ 5, we need to perform the division from left to right.
First, let's divide 100 by -10:
100 ÷ (-10) = -10
Next, let's divide the result by 5:
-10 ÷ 5 = -2
Therefore, the quotient of 100 ÷ (-10) ÷ 5 is -2.
What is the quotient of 842.4 ÷ −0.6 ?(1 point) Responses
To find the quotient of 842.4 divided by -0.6, we can perform the division calculation:
842.4 ÷ (-0.6) = -1404
Therefore, the quotient of 842.4 ÷ -0.6 is -1404.
What is 4.65 converted to a fraction? The answer should be given in simplest form.
To convert 4.65 to a fraction, we need to understand the decimal place value.
The number 4.65 can be written as 4 whole units, plus an additional 0.65.
Since 0.65 is in the hundredths place, we can write it as:
65/100
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which in this case is 5:
65 ÷ 5 / 100 ÷ 5 = 13/20
Therefore, 4.65 can be simplified as the fraction 13/20.
Use long division to convert 6715 to a decimal.(1 point) Responses ≈6.14285 approximately equals 6.14285 ≈0.46 approximately equals 0.46 ≈6.47 approximately equals 6.47 6.715 6.715
To convert 6715 to a decimal using long division, we divide 6715 by 1000:
6.715
-----------------
1000 | 6715
The quotient is approximately 6.715.
Therefore, 6715 as a decimal is approximately 6.715.
A pilot is flying an airplane. Due to strong winds, the pilot decides to fly 4,000 feet lower to avoid excessive turbulence. It takes the pilot 3.5 minutes to make this adjustment. Interpret the quotient to describe the rate of change in the plane’s altitude. Give your answer to the nearest hundredth, and remember the plane is descending.(1 point)
To interpret the quotient describing the rate of change in the plane's altitude, we can divide the change in altitude (4000 feet) by the time it takes to make the adjustment (3.5 minutes).
4000 feet / 3.5 minutes ≈ 1142.86 feet per minute
Therefore, the rate of change in the plane's altitude is approximately 1142.86 feet per minute (descending).
A fire engine’s water tank holds 750 gallons of water. If the pump removes 250 gallons of water in 5 minutes, what is the change in the amount of water in gallons in 1 minute?(1 point) Responses 15 15 −15 negative 15 −50 negative 50 50 50
To find the change in the amount of water in gallons in 1 minute, we can divide the change in water (250 gallons) by the time (5 minutes).
250 gallons / 5 minutes = 50 gallons per minute
Therefore, the change in the amount of water in gallons in 1 minute is 50 gallons.
Use the properties of operations and rules for multiplying and dividing signed numbers to solve: (−4)×(7/15)×(−3/4)÷(7/15)
To solve the expression (-4) × (7/15) × (-3/4) ÷ (7/15), we can follow the order of operations, which is parentheses, multiplication/division from left to right, and then addition/subtraction from left to right.
First, we simplify the multiplication:
(-4) × (7/15) = -28/15
Next, we simplify the division by reciprocating the divisor and multiplying:
(-28/15) ÷ (7/15) = (-28/15) * (15/7) = -4
Therefore, the expression simplifies to -4.
Solve the following word problem. A fish is swimming at −10.8 meters, or 10.8 meters below sea level. Every 2 minutes it descends another 1.5 meters. How long will it take for the fish to reach a depth of −37.8 meters? Show your work and write a sentence to explain what your answer means.
To find out how long it will take for the fish to reach a depth of -37.8 meters, we can subtract the initial depth (-10.8 meters) from the target depth (-37.8 meters) and then divide it by the rate at which the fish descends (1.5 meters every 2 minutes).
Target depth - Initial depth = -37.8 - (-10.8) = -37.8 + 10.8 = -27 meters
Time = Depth / Rate = -27 / 1.5 = -18
Since time cannot be negative, we can interpret this as 18 minutes.
Therefore, it will take the fish 18 minutes to reach a depth of -37.8 meters.
