Ilya [14]3 years ago
5 0

Answer:

The answer may be slightly off for a multiple choice question. but for fill in the blank, it should be fine to plur 340.83 as the answer

Step-by-step explanation:

First you find the percentage of tye 1st event

That would be represented by "56 is what percentage of 345?"

to find this, divide 56 by 345, which is .1623

then multiply is by 100 which is 16.23

This says that 16.23 percent of the cars that passed by were SUVS.

Finally, find what 16.23 percent of 2100 would be.

divide 2100 by 100 which is 21. then multiply it by 16.23 which is 340.83.

The diameter of a sphere is 21.6 cm. What is the sphere's volume? Round to the nearest tenth, if necessary.
NeX [460]
By definition, the volume of a sphere is:
 V =  \frac{4}{3}  (\pi) (r ^ 3)

 Where,
 r: sphere radio
 Substituting values we have:
 V =  \frac{4}{3}(3.14)(( \frac{21.6}{2} ) ^ 3)

 V = 5273.99424
 Rounding the result to the nearest tenth:
 V = 5274.0 cm ^ 3
 Answer:
 the sphere's volume is:
 V = 5274.0 cm ^ 3

Can someone please answer this really quick question?
julia-pushkina [17]

|2x-3|=2x-1

need to consider two cases

(1) 2x-3<0 --> x<3/2

-(2x-3)=2x-1

x=1, and this is <3/2 so that's a valid solution

(2) 2x-3>=0 --> x>=3/2

2x-3=2x-1

-3 = -1 so there no solution for x>=3/2


The single solution is x=-1

Will give 50points Pleasee help urgent!
Lorico [155]

Answer:

a = 10; a = 2

Step-by-step explanation:

Step 1: Use the Pythagorean theorem to solve this equation

    1. Orignal eqaution: (a + 2)² + (a - 5)² = (a + 3)²

    2. Expand (a + 2)² + (a - 5)² which will give us 2a² - 6a + 29

    3. Expand (a + 3)² giving us a² + 6a + 9

    4. Simplified equation: 2a² - 6a + 29 = a² + 6a + 9

Step 2: Subtract 9 from both sides

    1. 2a² - 6a + 29 - 9 = a² + 6a + 9 - 9

    2. Simplify: 2a² - 6a + 20 = a² + 6a

Step 3: Subtract 6a from both sides

    1. 2a² - 6a + 20 - 6a = a² + 6a - 6a

    2. Simplify: 2a² -12a + 20 = a²

Step 4: Subtract a2 from both sides

    1. 2a² - 12a + 20 - a² = a² - a²

    2. Simplify: a² - 12a + 20 = 0

Step 5: Use the quadratic formula to solve for a

    1. Quadratic formula: a = -b += √b² - 4ac/2a

    2. Plug in the correct values: a = -(-12) += √(-12)² + 4(1)(20)/2(1)

    3. Simplify the numerator and denominator: 12 += 8/2

    4. Final equation: a = 12 - 8/2  or a = 12 + 8/2

    5. Hence, the answer is 10 or 2
