Answer:

10.285 miles

Step-by-step explanation:

Given that:

Upstream travel time = 5 hours

Return trip travel time = 3.6 hours

Let upstream travel speed = x mph

Downstream travel speed = x + 4 mph

Distance = speed * time

Upstream distance = x * 5 = 5x

Downstream distance = (x + 4) * 3.6

5x = (x + 4) * 3.6

5x = 3.6x + 14.4

5x - 3.6x = 14.4

1.4x = 14.4

x = 10.285714

x = 10.285 miles

Answer:

16>-15

Step-by-step explanation:

16>-f, if f = 15 - given equation

f= 15, so  subsitute 15 in -f. This gives us 16>-15 because, f = 15, and there was a minus making is negative.

Answer:

Step-by-step explanation:

Irrational Numbers

The irrational numbers are identified because, unlike rational numbers, they cannot be expressed as fractions, i.e., as the result of a division between two integers.

If a number is expressed with a limited number of decimals, it's always possible to write it as a rational.

For example, number 1.2319 can be written as 12319/10000.

Even if the number has an unlimited decimal expression, it could be expressed as rational if the decimal part is periodic. Number 2.33333... is rational because it's equivalent to the fraction 7/3.

We need to find an irrational number between 0.3101 and 0.3333.

Any number within the range with unlimited non-periodic decimals will do:

0.3189567363.... is a good example.

We'll choose the number

π/10 since π is a known irrational number and π/10=0.3141592... lies in the given interval.

Step-by-step explanation:

set that width is x

and length become 2X

P = 2×( X+ 2X )

200 = 6 X

X=33. 3

width = 33.3 inch

length = 66. 6 inch

Answer:

$108

Step-by-step explanation:

From the above question, we have the proportion:

Company A/Company B

= $9/$2 = x/x24

The next step is : We Cross Multiply

2x = $24 × $9

x = $24 × $9/2

x = $108

Therefore, she will invest in $108 company A if she invests $24 in company B.

Answer:

[tex]the \: number \: is \: 96[/tex]

Explanation:

[tex]let \: the \: number \: be \: = \: x [/tex]

[tex] \frac{x}{2} + x = 144[/tex]

[tex]2( \frac{x}{2} ) + 2(x) = 2(144)[/tex]

[tex]x + 2x = 288[/tex]

[tex]3x = 288[/tex]

[tex] \frac{3x}{3} = \frac{288}{3} [/tex]

[tex]x = 96[/tex]

Answer:

C

Step-by-step explanation:

Answer:

D.)  y=5x+14

Step-by-step explanation:

point slope form: y-y1=m(x-x1)

y1=4, m=5, x1=-2

y-4=5(x+2)

distribute 5

y-4=5x+10

add 4 to both sides

y=5x+14

Answer:

(49x + 18) + 49y

Step-by-step explanation:

you woud place the variable (letter) representing the number of weeks they worked by the amount they get paid each week then, you would add to whoever gets an extra amount of money, the y - intercept or in this case the extra 18 dollars one of them gets paid to whoever got paid that amount of extra money. :)

Answer:

C( 49x + 18 + 49y)

Answer:

vvvvvvvvvvvvvvvvvvvvvv is equal to 65654

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

Substitute the value of x into y = x² and y = [tex]2^{x}[/tex]

x = 1

y = 1² = 1 and y = [tex]2^{1}[/tex] = 2

x = 2

y = 2² = 4 and y = 2² = 4

Thus

x      y = x²      y = [tex]2^{x}[/tex]

Step-by-step explanation:

Use pythagorean thm to solve for the hypotenuse. so [tex]\sqrt{36+144}[/tex] is 13.4

Answer:

k = 9

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 8

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, k)

m = [tex]\frac{k-1}{0+1}[/tex] = k - 1 = 8 ( add 1 to both sides )

k = 9

Answer:

[tex]m=\frac{-5}{2}[/tex]
