The depth of snow melting on a sidewalk changes over time. The equation below represents
the depth (d) in inch(es) as time (t) passes. How many inches deep is the snow just before
it begins to melt?
d = -0.51 + 7
0.5 inch
7 inches
-0.5 inch
-7 inches

Answer: 14 inches

Step-by-step explanation:

If one is 4 times the length of the other, then you'll have to divide by 5 because that's how many times there are in total. So 70/5 would be 14 which is the length of the smaller one. 70-14= 56 which is the length of the normal one.

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

For a point to be the midpoint of a line segment, it must bisect it into two equal segments and be on the line segment (hence, colinear with the endpoints). All four B points are equidistant from points A and C, but aren’t colinear with A and C. Therefore, they aren’t all midpoints of line segment AC.

Answer:

132-110(the original price)= 22

Step-by-step explanation:

114+18=132

Because you would add 20% to 100% which makes it 120% and then you would solve like any other percent. Thus getting 110 as the original price.

Answer:

The value of x at this instant is 3.

Step-by-step explanation:

Let [tex]x\cdot y = 18[/tex], we get an additional equation by implicit differentiation:

[tex]x\cdot \frac{dy}{dt}+y\cdot \frac{dx}{dt} = 0[/tex] (1)

From the first equation we find that:

[tex]x = \frac{18}{y}[/tex] (2)

By applying (2) in (1), we get the resulting expression:

[tex]\frac{18}{y}\cdot \frac{dy}{dt}+y\cdot \frac{dx}{dt} = 0[/tex] (3)

[tex]y\cdot \frac{dx}{dt}=-\frac{18}{y}\cdot \frac{dy}{dt}[/tex]

[tex]\frac{dx}{dt} = -\frac{18}{y^{2}} \cdot \frac{dy}{dt}[/tex]

If we know that [tex]y = 6[/tex] and [tex]\frac{dy}{dt} = 8[/tex], then the first derivative of x in time is:

[tex]\frac{dx}{dt} = -\frac{18}{6^{2}} \cdot (8)[/tex]

[tex]\frac{dx}{dt} = -4[/tex]

From (1) we determine the value of x at this instant:

[tex]x\cdot \frac{dy}{dt} = -y\cdot \frac{dx}{dt}[/tex]

[tex]x = -y\cdot \left(\frac{\frac{dx}{dt} }{\frac{dy}{dt} } \right)[/tex]

[tex]x = -6\cdot \left(\frac{-4}{8} \right)[/tex]

[tex]x = 3[/tex]

The value of x at this instant is 3.

The value of [tex]x[/tex] at the instant when particle moves on the hyperbola [tex]xy=18[/tex] from time [tex]t\geq 0\;\rm seconds[/tex] is [tex]3[/tex].

Differentiating the given equation  [tex]xy=18[/tex] with respect to the [tex]'t'[/tex] to get an addition equation by  implicit differentiation,

[tex]x\dfrac{dy}{dt}+y\dfrac{dx}{dt}=0----(i)[/tex]

Also, from the given equation, we can write [tex]x=\dfrac{18}{y}[/tex]

Substitute the value of [tex]x[/tex] in the equation (i), we get

[tex]\begin{aligned}\dfrac{18}{y}\dfrac{dy}{dt}+y\dfrac{dx}{dt}&=0\\\dfrac{dx}{dt}&=-\dfrac{-18}{y^2}\dfrac{dy}{dt}\end{aligned}[/tex]

Substitute the value of [tex]y=6[/tex] and [tex]\dfrac{dy}{dt}=8[/tex] in the above equation, we get

[tex]\begin{aligned}\dfrac{dx}{dt}&=-\dfrac{-18}{y^2}\dfrac{dy}{dt}\\&=\dfrac{-18}{6^2}\times 8\\&=-4\end{aligned}[/tex]

Now, from equation (i), we can re-write the expression to evaluate the value of [tex]x[/tex] at that instant as-

[tex]x=-y\dfrac{\frac{dx}{dt}}{\frac{dy}{dt}}\\x=-6(\dfrac{-4}{8})\\x=3[/tex]

Hence, the value of [tex]x[/tex] at the instant when particle moves on the hyperbola [tex]xy=18[/tex] from time [tex]t\geq 0\;\rm seconds[/tex] is [tex]3[/tex].

Complete Question:

The city of Paris, France is completely contained within an almost circular road that goes around the edge. The radius is 3 miles. Use the map with its scale to estimate the circumference and area of Paris.

(See attachment for map)

Answer:

[tex]C = 18.84\ miles[/tex]

[tex]A = 28.26\ miles^2[/tex]

Step-by-step explanation:

Given

[tex]Radius = 3\ miles[/tex]

Solving (a): Circumference

Circumference (C) is calculated as thus:

[tex]C = 2\pi r[/tex]

Where

[tex]r = radius = 3[/tex]

and

[tex]\pi = 3.14[/tex]

So:

[tex]C = 2 * 3.14 * 3[/tex]

[tex]C = 18.84\ miles[/tex]

Hence, the circumference is about 18.84 miles

Solving (b): Area

Area (A) is calculated as thus:

[tex]A = \pi r^2[/tex]

Where

[tex]r = radius = 3[/tex]

and

[tex]\pi = 3.14[/tex]

[tex]A = 3.14 * 3^2[/tex]

[tex]A = 3.14 * 9[/tex]

[tex]A = 28.26\ miles^2[/tex]

Hence, the area is about 28.26 mi²

Circumference and Area of Paris is 18.84 mile and 28.26 miles²

According to map

Radius of Paris = 3 miles

Circumference of Paris  = 2πr

Area of Paris = πr²

Circumference of Paris in miles = 2(3.14)(3)

Circumference of Paris in miles = 18.84 miles

Area of Paris = πr²

Area of Paris = (3.14)(3)²

Area of Paris = (3.14)(9)

Area of Paris = 28.26 miles²

Answer:

16 kilometers per hour

48 kilometers

Step-by-step explanation:

10m/ph -> km/hr

since 1 mile is equal to 1.6 kilometers, we use this to convert.

10miles x 1.6 kilometers

10 x 1.6 = 16

so, the answer is 16 kilometers per hour

To find out how many kilometers they travel in three hours, we multiply our last answer times three.

16 x 3 = 48

48 kilometers

This is because the cyclist is traveling at 16 kilometers per hour so we multiply it by the three hours in the question.

Answer:

c=1.96

Step-by-step explanation:

2.1/c=1.5/1.4

2.1*1.4=1.5*c

2.94/1.5=1.5c/1.5

c=1.96

(x + 4) / (3x) - 5 / (2x)

= 2 (x + 4) / (6x) - 15 / (6x)   ………   multiply the first fraction by 3/3 and the second by 2/2 to get a 6 in both denominators

= (2 (x + 4) - 15) / (6x)   ………   combine the fractions

= (2x - 7) / (6x)   ………   simplify the numerator

so a = 2, b = -7, and c = 6.

The relation between wavelength and period of a wave is explained in the solution.

Wavelength is a characteristic of a wave that measures the distance between two points or particles that have the same phase of oscillation.

The relation between wavelength and period of a wave :-

In one period of a wave, one full cycle (peak through valley

and back to peak) passes by.

That means that the wave has moved by one wavelength.

Since speed is distance traveled / time spent, and a wave

moves a distance of one wavelength in a time of one

period, its speed must be:

speed = distance / time = wavelength / period

v = λ / p

We more often use frequency = 1 / period. Then:

speed = wavelength x frequency

v = λ x f
