Brian completed a 100 meter race in 11.74 seconds.Luis completed the race in 11.69 seconds.What was the difference between their times expressed as a fraction of a second?

Explanation:

Consecutive integers are integers that follow one right after another. For example, the set {3,4,5} represents consecutive integers.

Consecutive odd integers are a similar idea but that every value is odd. Example: {7,9,11,13}

Let x be some integer. If we multiply it by 2, then it's always even. So 2x is always even. Adding 1 to it makes it odd. So 2x+1 is odd.

The next odd integer after (2x+1) is (2x+3)

Add those two integers and set that sum equal to -60. Solve for x.

(2x+1)+(2x+3) = -60

4x+4 = -60

4x = -60-4

4x = -64

x = -64/4

x = -16

If x = -16, then

2x+1 = 2*(-16)+1 = -32+1 = -31

2x+3 = 2*(-16)+3 = -32+3 = -29

Then note how -31+(-29) = -60 which confirms our answers.

Explanation:

Add up all the frequencies that correspond to outcomes that are more than 3

So we'll add up the last three frequencies (since they correspond to outcomes of 4, 5 and 6 all of which are greater than 3) to get 20+30+38 = 88

We have 88 occurrences of rolling either a 4, a 5 or a 6. This is out of 200 rolls total.

The empirical (or experimental) probability of getting more than 3 on the die is 88/200 = 0.44

[tex] \frac{16 {x}^{2} + 27x}{6x} [/tex]

[tex] \frac{ {16x}^{2} }{6x} + \frac{27x}{6x} [/tex]

[tex] \frac{16x}{6} + \frac{27}{6} [/tex]

Answer:

mutual fund

Step-by-step explanation:

Step one:

given data

let say the investment plan will span for 5 years

so  for mutual fund

P= $1000

r= 7.5%= 0.075

t= 5

compound interest

A= P(1+r)^t

substituting

[tex]A= 1000(1+0.075)^5\\\\A=1000(1.075)^5\\\\A=1000*1.436\\\\A=$1436\\\\[/tex]

$1436

so  for bond

P= $1000

r= 7.5%= 0.075

t= 5

simple interest

A= P(1+rt)

substituting

[tex]A= 1000(1+0.075*5)\\\\A=1000(1+0.375)\\\\A=1000(1.375)\\\\A=1375\\\\[/tex]

A=$1375

$1375

I would go for mutual fund compounded interest because it offers extra

$61 (1436-1375) for the same investment capital

Answer:

The equation of the line segment AB is:

[tex]y = -2x+11[/tex]

The graph of the line segment AB is also attached.

Step-by-step explanation:

Given the points

Determining the slope between A(3,5) and B(5,1)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(3,\:5\right),\:\left(x_2,\:y_2\right)=\left(5,\:1\right)[/tex]

[tex]m=\frac{1-5}{5-3}[/tex]

[tex]m=-2[/tex]

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = -2 and the point (3, 5) in the equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 5 = -2(x-3)[/tex]

[tex]y-5 = -2x+6[/tex]

[tex]y = -2x+6+5[/tex]

[tex]y = -2x+11[/tex]

Therefore, the equation of the line segment AB is:

[tex]y = -2x+11[/tex]

The graph of the line segment AB is also attached.

Answer:

a. $583

b. $30,316

Step-by-step explanation:

a. Commission last week;

= 5,300 * 11%

= $583

b. Commission in 2011 assuming weekly earnings of $583.

= 583 * 52 weeks

= $30,316

Step-by-step explanation:

For table 1,

x =  20     36    56     80

y =  4        6       8       10

Taking 20/4 = 5

36/6 = 6

56/8 = 7

80/10 = 8

The value of x/y is not same in any of the cases. The constant of proportionality is different. It means x and y for this table is not proportional.

For table 2,

x = 28    42    56    70

y = 20    30    40    50

Taking 28/20 = 1.4

42/30 = 1.4

56/40 = 1.4

70/50 = 1.4

The value of x/y is same in each case. The constant of proportionality is same i.e. 1.4 in each case.

[tex]\dfrac{x}{y}=1.4\\\\\dfrac{y}{x}=\dfrac{1}{1.4}\\\\\dfrac{y}{x}=\dfrac{5}{7}\\\\y=\dfrac{5}{7}\times x[/tex]

So, y is 5/7 times of the x.

Answer:

c= 39.95 +0.15 (s + r) (take the 63 received and plug it in for r and 53.45 in for c then solve)

53.45= 39.95 +0.15 (s +63) (use the distributive property)

53.45 = 39.95 + 0.15s + 9.45 (combine like terms on the right side)

53.45 = 49.40 +0.15s (subtract 49.40 from both sides)

4.05 = 0.15s (divide both sides by 0.15 so isolate s)

Answer:

Megan went a total distance of 1 5/12 miles

Step-by-step explanation:

Here, we want to calculate the total distance worked around the track

We are told that she ran 9/12 and skipped 8/12

The total distance around the track will be the sum of these two

Mathematically, that will be;

9/12 + 8/12

= 17/12 = 1 5/12

Answer:

The first option

Step-by-step explanation:

2/9 x + 3 > 4 5/9

2/9x > 4 5/9 - 3

2/9x > 14/9

x > 14/9 ÷ 2/9

x > 7

The 4 in the symbol is the index of the radical sign √.

Whether you can write this expression on a calculator depends on the calculator... If you have one with a CAS (that is, a "computer algebraic system"), chances are there is a built-in button for things like square roots and cube roots, and possibly roots of higher indices. If not, you can always express a radical expression using a fractional exponent, such as

[tex]\sqrt x\iff x^{\frac12}[/tex]

or

[tex]\sqrt[3]{x}\iff x^{\frac13}[/tex]

or

[tex]\sqrt[4]{x}\iff x^{\frac14}[/tex]

and so on. So the given expression could be typed in as (16*x^6*y^7)^(1/4), for instance.

I'm guessing you have to simplify the given expression. You could end up with

∜(16x ⁶y ⁷) = ∜(2⁴ x ⁴ x ² y ⁴ y ³)

… = 2xy ∜(x ² y ³)

(assuming x and y are positive)

Answer:

y = -3/8(x + 2)^2 + 8

Step-by-step explanation:

vertex form is

y = a(x - b)^2 + c     where a is a constant and (b,c) is the vertex.

The maximum is at (-2, 8)  because x 8 = height and x =-2 is equn. of symmetry

So here we have

y = a(x - (-2))^2 + 8

y = a(x + 2)^2 + 8

Now at the point (-6, 2):

2 = a(-6+2)^2 + 8

2 = 16a + 8

16a = -6

1 = -3/8.

So our equation is y = 3/8(x + 2)^2 + 8

Answer:

This question is solved in detail below. Please refer to the attachment for better understanding of an Ellipse.

Step-by-step explanation:

In this question, there is a spelling mistake. This is vertices not verticles.

So, I have attached a diagram of an ellipse in which it is clearly mentioned where are the vertices of an ellipse.

Vertices of an Ellipse: There are two axes in any ellipse, one is called major axis and other is called minor axis. Where, minor is the shorter axis and major axis is the longer one. The places or points where major axis and minor axis ends are called the vertices of an ellipse. Please refer to the attachment for further clarification.

Equations of an ellipse in its standard form:

[tex]\frac{x^{2} }{a^{2} } + \frac{y^{2} }{b^{2} } = 1[/tex]

This is the case when major axis the longer one is on the x-axis centered at an origin.

[tex]\frac{x^{2} }{b^{2} } + \frac{y^{2} }{a^{2} } = 1[/tex]

This is the case when major axis the longer one is on the y-axis centered at an origin.

where major axis length = 2a

and minor axis length = 2b

Answer:

$465 at Back Street

$515 at Main Street

Step-by-step explanation:

980 (total) - 50 (the difference between the two) = 930

930/2 = 465 (back street)

465 + 50 (the difference) = 515 ( main street)

CHECK: 465 + 515 = 980
