Answer:
1.) -5
2.) -4
Step-by-step explanation:
For number 1, you sub in -2 for x.
2 multiplied by -2 is -4, minus 1 = -5.
For the second one, sub in 5 for x.
-5 + 1 = -4.
Answer: 376.98192 mL
Step-by-step explanation:
We are going to use this equation.
V = π * r² * h
according to the question we have the value for r and h, if you replace the values into the equation we will get following product:
note: also keep in mind that value of π is 3.141516
V = π * r² * h
V = π * (4in)² * (10in)
V = 502.64256 in³
after we can divide this value in 4 equals parts
then we get the following equation:
502.64256 in³ / 4 = 125.66064 in³
after that that you can multiply this value by 3 to get the 3 parts of the cylinder vase for example:
125.66064 in³ * 3 = 376.98192 in³
and this result is the volume of water that we have to pour into the vase
Its 16/75 if its one of ur options hope it helps
1. The answer to addition problems is referred to as the sum, multiplication as the product, subtraction as the difference and division as the quotient. So...False.
2. You could turn the percent into a decimal, after rounding to 25, and multiply it by 121 to get about 30. However, I find it easier to just move the decimal one place to the left and multiply the product by how many tens are in the estimated percent.
10% = .10 .10 x 121 = 12.1 x 3 = 36.3 Which is still rather close and doesn't need a calculator.
3. Using the methods earlier, I'd say the best estimate is 45.
Answer:
Since we know that ABCD is an isosceles trapezoid, we can also asume that its diagonals have the same length, which means:
AC = BD
=> 7x - 21 = 5x + 13
=> 7x - 5x = 21 + 13
=> 2x = 34
=> x = 34/2 = 17
So the answer is C.
