Answer:

Choice A. $\frac{2}{3}$

Step-by-step explanation:

Turn the mixed numbers into improper fractions:

$\frac{14}{9} /\frac{7}{3}$

Flip the second term and multiply:

$\frac{14}{9} /\frac{3}{7}$
$\frac{42}{63}$

Simplify:

$\frac{2}{3}$

Mariulka [41]

Let time be x distance be y

140x=y-(1)
290x=360-y-(2)

Put value in eq(2)

$\\ \rm\longmapsto 290x=360-(140y)$

$\\ \rm\longmapsto 440x=360$

$\\ \rm\longmapsto x=1.2min$

Put it in eq(1)

d=1.2(140)=168m

Is 7/8 or 11/10 closer to 1? How did you decide anybody help please?

erik [133]

Let

A-----> $\frac{7}{8}$

B-----> $\frac{11}{10}$

C-----> $1$

we know that

Point A-------> Multiply numerator and denominator by $10$

$\frac{7*10}{8*10} =\frac{70}{80}$

Point B-------> Multiply numerator and denominator by $8$

$\frac{11*8}{10*8} =\frac{88}{80}$

Point C-------> Multiply numerator and denominator by $80$

$\frac{1*80}{1*80} =\frac{80}{80}$

Find the distance Point A to Point C

$\frac{80}{80} -\frac{70}{80} =\frac{10}{80}$

Find the distance Point B to Point C

$\frac{88}{80} -\frac{80}{80} =\frac{8}{80}$

therefore

$\frac{8}{80} < \frac{10}{80}$

Point B is closer to Point C

$\frac{11}{10}$ is closer to $1$

the answer is

$\frac{11}{10}$ is closer to $1$

If each foot of water in a lake screens out 60% of the light above, what percent of the light passes through 5 feet of water?

BartSMP [9]

The amount of light passing through each foot the water in the lake = 100% - 60% = 40%
The percent of light passing through 5 feet of water = 0.4^5 = 0.01024 = 1.02%

Answer:

Slope of the line DV = -1

Step-by-step explanation:

Let point D (-5, 1) be $(x_{1}, y_{1})$

Let point V (-1, -3) be $(x_{2}, y_{2})$

$m=\frac{y_2-y_1}{x_2-x_1}$

Plug in the appropriate values,

$m = \frac{-3-1}{-1-(-5)} = \frac{-4}{4} = -1$

slope equals -1

Find an equation of the tangent line to the hyperbola: x^2/a^2 - y^2/b^2 = 1 at the point (x0,x1)

musickatia [10]

The standard form of a hyperbola is <span><span><span>x2/</span><span>a2 </span></span>− y<span><span>2/ </span><span>b2 = 1
the tangent line is the first derivative of the function</span></span></span><span>y′ = <span>b^2x/ a^2 y
hence the slope is </span></span><span>m = <span>b^2 x0 / <span>a^2 <span>x1

</span></span></span></span>Therefore the equation of the tangent line isy−x1 = b^2 x0 / a^2 x1* (x−x0)
