Debnil has 6 teaspoons of salt. The ratio of teaspoons to tablespoons is 3:1 How many tablespoons does Debnil have?

A. 1/18

B. 1/2

C. 2

D.18​

Answer : The correct option is, (C) 2

Step-by-step explanation :

As we are give that Debnil has 6 teaspoons of salt.

The ratio of teaspoons to tablespoons is 3 : 1.

It means,

if he has 3 teaspoons then he has 1 tablespoons

if he has 1 teaspoons then he has [tex]\frac{1}{3}[/tex] tablespoons

So,

if he has 6 teaspoons then he has [tex]6\times \frac{1}{3}=2[/tex] tablespoons

Therefore, Debnil have 2 tablespoons of salt.

The number of tablespoons that debnil has is;

C: 2

We are told that;

Thus, if the total spoons is x. Then;

¾x = 6

Thus;

x = (4 × 6)/3

x = 8 spoons

Thus, number of tablespoons she has = 8 - 6 = 2

Answer:

L=15  W=12   15*12 = 180

Step-by-step explanation:

W*L = area

W*(W+3) = 180

Do the distributive

W^+3 W-180=0

Find 2 numbers that when multiplied ,the result is -180

and when added the result is 3

      - 12* 15  = -180

Last year's salary is $32000

Step-by-step explanation:

We will use the linear equations to solve the given problem

Let x be the last years salary

then

0.06x will be the raise in the salary

This year's salary is $33920

So,

[tex]x+0.06x=33920\\1.06x=33920[/tex]

Dividing both sides by 1.06

[tex]\frac{1.06x}{1.06}=\frac{33920}{1.06}\\=32000[/tex]

[tex]\cos x=-\dfrac{\sqrt{21}}{5}\\ \\\tan x =-\dfrac{2}{\sqrt{21}}\\ \\\cot x=-\dfrac{\sqrt{21}}{2}[/tex]

Step-by-step explanation:

Given

[tex]\sin x=\dfrac{2}{5}\\ \\\cos x<0[/tex]

Use formula:

[tex]\cos^2x+\sin ^2x=1\\ \\\cos^2x+\left(\dfrac{2}{5}\right)^2=1\\ \\\cos^2x=1-\dfrac{4}{25}\\ \\cos^2x=\dfrac{21}{25}\\ \\\cos x=\pm \dfrac{\sqrt{21}}{5}[/tex]

Since [tex]\cos x<0,[/tex] then

[tex]\cos x=-\dfrac{\sqrt{21}}{5}[/tex]

By definition,

[tex]\tan x =\dfrac{\sin x}{\cos x}=\dfrac{\frac{2}{5}}{-\frac{\sqrt{21}}{5}}=-\dfrac{2}{\sqrt{21}}\\ \\ \\\cot x=\dfrac{1}{\tan x}=\dfrac{1}{-\frac{2}{\sqrt{21}}}=-\dfrac{\sqrt{21}}{2}[/tex]

Answer:

f(x) = |x| or f(x) = x² etc.

Step-by-step explanation:

There are several functions that gives positive value for entire interval [-3,-2].

Like the function, y = |x| , where if you put any negative value of x, the resulting output of the value of y is always positive. Therefore, for domain of [-3,-2] the range of the function will be [3,2]

Again, the function y = x², where if you put any negative number as a value of x, the corresponding value of y will be always positive.

Therefore, for domain of [-3,-2] the range of the function will be [9,4] (Answer)

Answer:

The function f(x) has a hole at point x = - 5.

Step-by-step explanation:

We are given a function as

[tex]f(x) = \frac{x^{2} + 7x + 10}{x^{2} + 9x + 20}[/tex]

Now, we have to describe where the function has a hole.

Now, [tex]f(x) = \frac{x^{2} + 7x + 10}{x^{2} + 9x + 20}[/tex]

⇒ [tex]f(x) = \frac{(x + 5)(x + 2)}{(x + 4)(x + 5)}[/tex]

Therefore, the common factor of the numerator and denominator is (x + 5).

Now, (x + 5) = 0

⇒ x = - 5

Therefore, the function f(x) has a hole at point x = - 5. (Answer)

By factoring and simplifying the function f(x)=(x^2+7x+10)/(x^2+9x+20), we find a hole at x=-5. This is because -5 was an excluded value in the original function, but does not cause the denominator to be zero in the simplified function.

The given function is f(x) = (x^2+7x+10) / (x^2+9x+20). To find where the function has a hole, we need to factor both the numerator and the denominator. We also must exclude any values of x that would cause the denominator to be zero as these are undefined in the function.

The numerator factors into (x+2)(x+5), and the denominator into (x+4)(x+5). If we simplify, the x+5 term will cancel out, leaving us with f(x) = (x+2)/(x+4).

Originally, x could not be equal to -4 or -5, as these would make the denominator zero. In the simplified function, only x=-4 causes the denominator to be zero. But since x=-5 was an excluded value in the original function, that indicates there is a 'hole' at x=-5 on the function.

Step-by-step explanation:

The question is about finding the final amount after 4 years of a $700 investment with 8% interest, compounded quarterly. This can be solved using the compound interest formula.

The subject of your question pertains to compound interest in mathematics. Given the parameters, we want to find the amount after 4 years when $700 is invested at an interest rate of 8%, compounded quarterly. To solve this, we can use the compound interest formula, A = P(1 + r/n)^(nt), where 'A' is the amount of money accumulated after n years, including interest, 'P' is the principal amount (the initial amount of money), 'r' is the annual interest rate (in decimal form), 't' is the time the money is invested for in years, and 'n' is the number of times that interest is compounded per year. Plugging the values in, we get A = $700(1 + 0.08/4)^(4*4) which gives us the total amount after 4 years.

Answer:

65%

Step-by-step explanation:

Cross, multiply and divide method has saved my life with these problems, heres how to do it.

Set up like this:

143 x

------- = -------

220 100

Multiply 143 by 100, then divide that by 220.

x= 65, so she has read 65%

Final answer:

Olivia has read approximately 65% of her 220-page novel by reading 143 pages.

Explanation:

To calculate the percent of the novel that Olivia has read, we use the formula: (number of pages read ÷ total number of pages) × 100%. Olivia has read 143 pages of a 220-page novel. Therefore, the calculation is (143 ÷ 220) × 100%, which simplifies to approximately 65%.

The steps to solve the problem are given below:

Step 1: 143 / 220 = 0.65

Step 2: 0.65 x 100 = 65%

So, Olivia has read about 65% of the novel.

Answer:

The volume in liters is 2.041165665 liter.

Step-by-step explanation:

Given : Clare wants to mail a package that weighs [tex]4\frac{1}{2}[/tex] pounds.

To find : What could be its volume in liters ?

Solution :

We know that,

Pound (lb) is a unit of Weight used in Standard system.

Liter (l) is a unit of Volume used in Metric system.

To convert 1 pound into liter is

1 pound (lb) = 0.45359237 liter (l)

[tex]4\frac{1}{2}[/tex] pounds in simpler fraction is [tex]\frac{9}{2}[/tex]

Converting into liter,

[tex]\frac{9}{2}[/tex] pound (lb)=[tex]\frac{9}{2}\times 0.45359237[/tex] liter (l)

[tex]\frac{9}{2}[/tex] pound (lb) = 2.041165665 liter (l).

Therefore, the volume in liters is 2.041165665 liter.

[tex]h^{-1}(x) = \frac{2x-8}{5}[/tex]

Step-by-step explanation:

Given function is:

[tex]h(x) = \frac{5}{2}x+4[/tex]

In order to find the inverse:

Replacing h(x) with y

[tex]y = \frac{5}{2}x+4[/tex]

Replacing x with y and y with x

[tex]x = \frac{5}{2}y+4[/tex]

Solving for y

[tex]x = \frac{5}{2}y+4\\x - 4 = \frac{5}{2}y+4-4\\x-4 = \frac{5}{2}y\\y = \frac{2}{5}(x-4)\\y = \frac{2x-8}{5}[/tex]

Replace y with h^(-1)(x)

[tex]h^{-1}(x) = \frac{2x-8}{5}[/tex]

Hence,

[tex]h^{-1}(x) = \frac{2x-8}{5}[/tex]

The annual rate of interest per year is 8%

Solution:

Given:- Principal (p) = 4600 rupees, Time –Period (t) = 5 years, Total amount(A) = 6440 rupees

First we will calculate the Interest and then using formula of simple interest we will calculate the rate of interest

Interest = Amount – Principal

Interest = 6440  – 4600 = 1840

Now using the formula of simple Interest and on putting values we get,

[tex]\text {Simple Interest }=\frac{P \times R \times T}{100}[/tex]

Where "P" is the principal and "R" is the rate of interest per annum and "T" is the time period

[tex]1840=\frac{4600 \times R \times 5}{100}[/tex]

Step-by-step explanation:

so we do the same thing like last time and 8√2 rounded is 11.3, and 7/√3, or 7√3/3 is 4( 4.04 gets rounded down). now we multiply by two because of the theorems and get 8(if this is wrong then try 8.1 because the answer differs depending on what you do first.)

When trying to find the point-slope equation of a line you need to pick a point and plug it into the plain equation with your slope.

Move the -1/3 to the other side by doing the opposite operation, in this case being addition.

-3 +1/3 = b

-2 2/3 = b
