You are going to use an incline plane to lift a heavy object to the top of a shelving unit with a height of 6 ft. The base of the incline plane is 10 ft from the shelving unit. What is the length of the incline plane?

Answers

Final answer:

To determine the length of an inclined plane given the height (6 ft) and base (10 ft), use the Pythagorean theorem, which reveals that the length of the inclined plane is approximately 11.66 feet.

Explanation:

The student is asking about the length of an inclined plane when given the height and the base of the incline. To find the length of the inclined plane, we can use the Pythagorean theorem because the height, base, and the length of the incline form a right triangle.

The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, the hypotenuse is the length of the incline, the vertical side is the height of the shelving unit (6 ft), and the horizontal side is the base of the incline (10 ft).

The formula is: length of the incline2 = height2 + base2. Plugging in the numbers, we get: length of the incline2 = 62 + 102, which simplifies to length of the incline2 = 36 + 100. The square root of 136 gives us the length of the incline, which is approximately 11.66 feet.

The sum of three consecutive numbers is 42. What are the three numbers?

Answers

Answer:

13,14,15

Step-by-step explanation:

Let x be the first number

x+1 is the second number

x+2 = third number

x+ x+1 +x+2 = 42

Combine like terms

3x+3 =42

Subtract 3 from each side

3x+3-3 = 42-3

3x = 39

Divide each side by 3

3x/3 = 39/3

x = 13

The numbers are 13

13+1 =14

13+2 = 15

Answer:

13,14,15

Step-by-step explanation:

What three consecutive integers have a sum of 42? Which means that the first number is 13, the second number is 13 + 1 and the third number is 13 + 2. Therefore, three consecutive integers that add up to 42 are 13, 14, and 15.

The sum of -4 and 5 times a number is multiplied by 3. The result is 212 less than 7 times the number. What is the number?

Answers

Answer:

104

Step-by-step explanation:

First, put the word equation into a numerical equation.

-4+5x=7x-212 This is our equation

-4=2x-212 I subtracted 5x from both sides

208=2x I added 212 to both sides

104=x I divided both sides by 2

Final answer:

To solve the problem, we can set up an equation and solve for the variable 'x'. The number is x = -25.

Explanation:

To solve this problem, we can translate the given information into an equation. Let's assume the number is 'x'. The sum of -4 and 5 times 'x' is -4 + 5x. The equation becomes 3(-4 + 5x) = 7x - 212. We can simplify this equation and solve for 'x' to find the number.

First, distribute the 3 to -4 and 5x, which gives us -12 + 15x = 7x - 212. Then, combine like terms by subtracting 7x from both sides, which gives us -12 + 8x = -212. Next, add 12 to both sides to isolate the variable, resulting in 8x = -200. Finally, divide both sides by 8 to solve for 'x'. The number is x = -25.

#SPJ1

One day, River writes down the numbers $1,$ $2,$ $\dots,$ $999.$ River chooses one of the digits written down at random. What is the probability that River chooses a $7$?

Answers

Answer:

100/963

Step-by-step explanation:

The number 1,2,3,...,999 is written down.

First, we determine the total number of digits written down

1-9 =9 digits 10-99= 2(99 - 10 + 1) =2(90) digits100-999=3(999 - 100 + 1) =3(900) digits

Total Number of digits=9+2(90)+3(900) =2889

Number of Digit 7 between 1 and 999

In the Units’ place, 7 occurs once every decade (7, 017… 997)=10 X 10= 100 times In the Tens place, 7 occurs in the ten times every century (70–79, 170–179, …, 970–979) =10 X 10= 100 times In the hundreds’ place, 7 occurs once in the hundreds’ place (700, 701, …, 799) = 100 times

Therefore, the number 7 will be found a total of 300 times between 1 and 999.

Therefore, the probability of selecting a "7" = 300/2889

= 100/963

Final answer:

The probability that River chooses a 7 from the numbers 1 to 999 when randomly selecting a digit is approximately 0.111 or 11.1%. This is calculated by dividing the total occurrences of the digit 7 (321 times) by the total number of digits written (2889 digits).

Explanation:

To calculate the probability that River chooses a 7 from the numbers 1 to 999 when randomly selecting a digit, we must first determine the total number of times the digit 7 appears in this range. In numbers 1-9, 7 appears once; in numbers 10-99, it appears 10 times in the units place plus 10 times in the tens place; and in numbers 100-999, it appears 100 times in the units place, 100 times in the tens place, and 100 times in the hundreds place. Therefore, there are a total of 1 + 10 + 10 + 100 + 100 + 100 = 321 occurrences of the digit 7.

Next, we calculate the total number of digits written down from 1 to 999. For numbers 1-9, there are 9 digits. For 10-99, there are 90 numbers times 2 digits each, totaling 180 digits. For 100-999, there are 900 numbers times 3 digits each, totaling 2700 digits. The sum of all digits is 9 + 180 + 2700 = 2889 digits.

The probability that River chooses a 7 is the number of 7s divided by the total number of digits, which is 321/2889. Simplifying this fraction, we get a probability of approximately 0.111 or 11.1%.

The given triangle QRS is an isosceles triangle because [tex]QR = RS[/tex].

What is an isosceles triangle?

An isosceles triangle is a triangle that has two equal sides.

In the given triangle, the length of the sides are as follows:

[tex]QR = \sqrt{9 + 27.04} = \sqrt{36.04} = 6.003[/tex]

[tex]QS = \sqrt{64 + 3.53} = \sqrt{67.53} = 8.218[/tex]

[tex]RS = \sqrt{25 + 11.04} = \sqrt{36.04} = 6.003[/tex]

(Negative values are not taken)

In the given triangle, [tex]QR = RS[/tex].

Therefore, the given triangle QRS is an isosceles triangle.
