How many tiles measuring 20cm by 50cm are needed to completely cover a wall 4m by 8m?

the whole answer to the differential equation used to model the statement. The relationship between the rate of change of n and n is (dN/dt)=kN.

A differential equation in mathematics is an equation that connects the derivatives of one or more unknown functions. Applications often involve functions that reflect physical quantities, derivatives that depict the rates at which those values change, and a differential equation that establishes a connection between the three.

According to given data;

The derivative of N with respect to t, or (dN)/(dt), represents the rate of change of N.

dN/dt = kN, where k is the proportionality constant, if the rate of change of N is proportional to N. We must solve this differential equation.

To solve it, separate the variables:

(dN)/N = kdt

Integrating both sides results in

ln N = kt + C , where C is another constant.

This can be rewritten in exponential form as

N = e^(kt + C)

= N_0e^(kt) .

Here, N_0 = e^C

and it equals N(t) when t = 0.

Based on the number of batches of cupcakes, the pounds of sugar in each batch can be found to be 3 / 16 pounds

Find out more below

The total number of pounds of sugar that Polly used was 15/16 pounds of sugar and she used these to make 5 batches of cupcakes.

Each of this batches of cookies used the same amount of sugar so the amount of sugar per batch of cookie is:

= Total number of pounds of sugar used / Number of batches of sugar

Solving for the pounds of sugar gives:

= 15/16 ÷ 5

= 15/16 x 1/5

= 15 / 80

The standard form of the line that contains a slope of -3/2 and y-intercept of 6 is y = (-3/2)x + 6.

The slope intercept form of a line is:-

y = mx + c

Where,

m represents the slope of the line,

(x,y) represents the ordered pair of coordinates of each point on the line, and

c is the y-intercept

The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis).

Hence, we have,

m = -3/2

c = 6

The line segment NO of the triangle MNO, that is similar to the triangle QRS, has a length of 25 meters.

In this problem we have a system of two similar triangles. Two triangles are proportional when the sides of a triangle are proportional to the corresponding sides of the other triangle. Herein we find the following relationship:

MN / QR = NO / RS = MO / QS

If we know that QR = 1 m, MN = 5 m and RS = 5 m, then the length of the line segment NO is:

NO = (MN / QR) · RS

NO = (5 m / 1 m) · 5 m

NO = 25 m

The line segment NO has a length of 25 meters.

The smallest angle of the right triangle is 27 degrees.

A right triangle is a triangle that has one of its angles as 90 degrees.

The sum of angles in a triangle is 180 degrees.

Therefore, the measure of the smallest angle in the triangle can be found as follows:

90 + 6x + 3 + 2x + 7 = 180

combine like terms

90 + 6x + 3 + 2x + 7 = 180

6x + 2x + 90 + 3 + 7 = 180

8x + 90 + 10 = 180

8x + 100 = 180

subtract 100 from both sides of the equation

8x + 100 = 180

8x + 100 - 100 = 180 - 100

8x = 80

divide both sides by 8

8x / 8 = 80 / 8

x = 10

angle 1 = 6(10) + 3 = 60 + 3 = 63°

angle 2 = 2(10) + 7 = 20 + 7 = 27°

Therefore,

smallest angle of the triangle = 27 degrees.

The unknown length is 28. the values of the six trigonometric functions for angle b that is tan B = 7/24

From the question,

we are given

a = 96 and c = 100, to get the unknown side 'b',

we will substitute the given values into the formula above;

c² = a²+b²

100²  = 96² +b²

b²  = 100²  - 96²

b²  = 10,000 - 9216b²

= 784b = √784b = 28

Hence, the unknown length is 28.

To get tanB, we will use the SOH, CAH, TOA trigonometry identity.

According to TOA,

tan B = opposite/adjacenttan B = b/a (note that side b is the opposite in this case since the angle we are considering is B)

Given that,

Riley's phone had a 50% charge when she left her home in the morning. Equation B = 40 - 5t, where t is the number of hours since Riley left her residence, can be used to predict the percentage of charge still in Riley's battery.
