Here is some information about a heating oil tank.
Top Outlet Tank
Height (h): 2550 mm
Diameter (d): 2100mm
Mass: 650kg

(b) Work out the volume, in cubic metres, of the tank.

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.

There is a typing mistake in the statement, correct form is introduced below:

Given ΔMNO and ΔQRS are similar triangles. If QR = 1 meters, MN = 5 meters and RS = 5 meters. What does line NO equal to?

Answer:

RS = 9

X = 3

Step-by-step explanation:

Because QS = QR + RS

QR = 11

RS = 3x

QS = 7x -1

So ...

11 + 3x = 7x - 1

+1

12 + 3x = 7x

             -3x

12 = 4x

/ 4

x = 3

3(3) = 9

RS is 9

When two dice are rolled one time, the probability of getting a sum of 11 is 1/18.

From the information, two dice are rolled one time. There are 6 different possibilities and the outcomes of rolling the dice will be:

= 6 × 6 = 36

It should be noted that the sum of 11 can be gotten as (6, 5) and (5, 6). That's 2 out of 36.

Therefore, the probability will be:

= 2 / 36

= 1 / 18

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

Hence, the standard form of the line that contains a slope of -3/2 and y-intercept of 6 is given by:-

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.

Step-by-step explanation:

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.

The number of groups of 5/7 that are in 1 is 1 2/5.

when 8 is divided by 5/7, the quotient is 11 1/5.

A proper fraction is a non-integer in which the numerator is less than the denominator. The numerator is the number above and the denominator is the number below. An example of a proper fraction is 5/7.

In order to determine the groups of 5/7 are in 1, divide 1 by 5/7. Division is the process of determining the quotient of two or more numbers.  Division is the process of grouping a number into equal groups using another number.  The sign that denotes division is ÷.

1 ÷ 5/7

1 x 7/5 = 7/5 = 1 2/5

8 ÷ 5/7

8 x 7/5 = 56 / 5 = 11 1/5

Riley's phone had a 50% charge when she left her home in the morning. Equation B = 40 - 5t. The x-intercept of the equation is (8,0). After 8 hours, Riley battery has no charge left in it ( since Riley left her house).

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.

We have to find what is the equation's x-intercept and how is it interpreted in the problem's context.

The equation B=40-5t can be used to model Lauren's battery charge remaining as a percentage when t is the number of hours since she left her home.

Put B = 0 to determine the x-intercept. (In this case, the independent variable is "t," as x signified the independent variable).

0=40-5t

5t=40

t=40/5

t=8

Therefore, the x-intercept of the equation is (8,0).

After 8 hours, Riley battery has no charge left in it ( since Riley left her house).
