The whole second is the first number to the left of the decimal (_.)

So, 35.78 = 36 because 7>5.

39.51 = 40 because 5 = 5.

40 - 36 = 4.

Bailey won the race by about 4 seconds.

Answer:

The estimate time by which Bailey wins the race by Elena is:

4 seconds.

Step-by-step explanation:

The times of completion of a swim race by Bailey and Elena are given as:

Bailey: 35.78 seconds  

Elena: 39.51 seconds

Clearly from the time we could observe that the time taken by Bailey is less as compared to Elena.Hence, Bailey wins the race.

Hence, the time taken by them to the nearest second is:

Bailey: 36 seconds.

Elena: 40 seconds.

Hence, the estimate time by which Bailey wins by Elena is:

40-36=4 seconds.

Hence, the estimate time is:

4 seconds.

HELP WITH THIS MATH PROBLEM 93. Points
nadya68 [22]

Answers:

4;  20;  3x² - 4x + 3; 52;  17

Step-by-step explanation:

f(-1):  replace x in f(x) = x² + 3 with -1:  f(-1)  =  (-1)² + 3 = 4

f(-4) + g(-1) = (-4)² + 3 + <em>2(-1) + 3</em>  =  16 + 3 <em>- 2 + 3</em> = 20   <em>(since g(x) = 2X + 3)</em>

<em />

3f(x) - 2g(x) = 3[x² +3] - 2[2x + 3} = 3x² + 9 - 4x - 6  =  3x² - 4x + 3

f(g(2)):  First, evaluate g(2).  It is g(2) = 2(2) + 3 = 7.  Next, use this output, 7, as the input to f(x):    f(g(x)) = (7)² + 3 = 49 + 3 = 52

g(f(2)):  First, evaluate f(x) at x = 2:  f(2) = (2)² + 3 = 7.  Next, use this 7 as the input to g(x):     g(f(2)) = g(7) = 2(7) + 3 = 17

What is 2(x + 4)=2(-8- x) - 2x
Maru [420]

Answer:

You want to solve for x, the first thing you need to do is distribute

The 2 through the x+4 then the other 2 through the -8-x

2(x+4)= 2x+8

2(-8-x)= -16-2x

2x+8=-16-2x-2x (combine like terms on the right side)

2x+8=-16-4x (now subtract 8 from each side)

2x=-24-4x (8-8=0, -16-8=-24) (now add 4x to each side)

6x=-24 (-4x+4x=0, 2x+4x=6x), (divide each side by 6)

x=-4 (6/6=1, -24/6=-4)

x=-4

Hope this helps ;)

For each sentence, drag a word that will make the statement true.
olchik [2.2K]

Answer:

Equilateral triangles are always acute triangles.

Scalene triangles are sometimes acute triangles.

Right triangles are never acute triangles.

Obtuse triangles are sometimes isosceles triangles.

Step-by-step explanation:

Equilateral triangles are always acute because each angle is 60⁰.

Scalene triangles have sides that are different lengths. They can be right, obtuse, or acute.

A right triangle is never acute because it has a 90⁰ angle. Acute means all angles are less than 90⁰.

An obtuse triangle can be either scalene or isosceles. It always has one angle greater than 90⁰ (obtuse).
