Answer:

0.75°C

Step-by-step explanation:

Person A     Person B          Person C

-3                   4                      8

-1                   -4                     -2

0                    2                      5

2                     -3                   1

To get Fatima mean value, we have to add all the given values together  

= - 3 + 4 + 8 - 1 - 4 - 2 + 0 + 2 + 5  +  2  - 3  + 1

= 9  

Estimate is 9 deg above Actual Temperature in 12 readings

The formula for our Mean Value will be, the added values divided by actual temperatures  

Added values = 9  

Actual temperature = 12  

Mean value = 9 ÷ 12 = 0.75°C above actual Temperature

Answer:

234 ÷ g

Step-by-step explanation:

Convert "234 divided by g" into algebraic form, which is:

234 ÷ g

It can also be written as 234/g.

An expression is has no equal sign, as opposed to an equation, which has an answer.

The explicit function is f(n) = 3f(n - 1)

Given, sequence is 16, 48, 144, 432 ….

We have to find the explicit function.

Now, if we observe the given sequence, every term is three times its previous term.

That is, the next term in sequence is obtained by multiplying the previous term by 3

48 = 16 x 3

144 = 48 x 3

432 = 144 x 3

So, explicit function f(n) will be  

nth term = 3 x (n – 1)th term

F(n) = 3 x f(n – 1) [ since nth term is f(n)  ]

We derived the above function just by generalizing the sequence and making it into the function.

The nth term is obtained by multiplying the n - 1 term with 3

Hence explicit function is f(n) = 3f(n - 1)

[tex]c^2=a^2+b^2-2(a)(b)cos(C)[/tex]

where

[tex]a=7\ units\\b=8\ units\\c=10\ units\\C=\theta[/tex]

substitute in the formula

[tex]10^2=7^2+8^2-2(7)(8)cos(\theta)[/tex]

[tex]100=49+64-112cos(\theta)[/tex]

[tex]100=113-112cos(\theta)[/tex]

[tex]112cos(\theta)=113-100[/tex]

[tex]112cos(\theta)=13[/tex]

[tex]cos(\theta)=\frac{13}{112}[/tex]

Step-by-step explanation:

Gain percentage made by Mr William by selling the table at Rs. 1050 is 12.30%.

Given that  

Mr. William bought an old table for RS 850

Mr. William spent 1/10 of the cost price on its repairs.

Mr. William sold the table for Rs 1050.

Need to determine gain or loss percent.

Let’s first calculate total money spent by Mr William on Table

Total money spent by Mr William on Table = Amount at which Mr. William bought an old table + amount spent on repairs

[tex]=\text { Cost price }+\frac{1}{10} \text { of the cost price }=850+\frac{1}{10} \text { of } 850=850+85=935[/tex]

So Total money spent by Mr William on Table = 935

Money generated by selling the table = Rs 1050

As Money generated by selling the table is more that Total money spent by on Table so there is a gain.

Gain by selling the table = Money generated by selling the table - Total money spent by Mr William on Table

= 1050 – 935 = 115

[tex]\text { Gain percentage }=\frac{\text { gain amount }}{\text { Money spent on table }} \times 100[/tex]

[tex]=\frac{115}{935} \times 100=12.299 \approx 12.30 \%[/tex]

Hence gain percentage made by Mr William by selling the table at 1050 is 12.30%.

Explanation:

The expression that you want to simplify is:

This is the simplification step-by-step:

1. Mulitply the expressions on the numerator among them and the expressions on the denominator among them:

[tex]5x\times \frac{1}{x^{-7}}\times x^{-2}=\frac{5x\cdot x^{-2}}{x^{-7}}[/tex]

2. For equal bases that are multiplying, add the exponents:

[tex]\frac{5x\cdot x^{-2}}{x^{-7}}=\frac{5x^{1-2}}{x^{-7}}=\frac{5x^{-1}}{x^{-7}}[/tex]

3. Pass the power on the denominator to the numerator by changing its sign (negative exponents become positive when inverted)

[tex]\frac{5x^{-1}}{x^{-7}}=5x^{-1}x^{7}[/tex]

4. Simplify adding the exponents with the same base:

[tex]5x^{-1}x^{7}=5x^{-1+7}=5x^6[/tex]

And that is the final expression in its most simple form.

Answer:

The answer would be 22.

Step-by-step explanation:

Since we have 2 bases one being 5 and the other 10, if you multiply the base of the smaller triangle by 2 you get 10. Whatever the sides are for the smaller triangle multiply those by 2. ONce you get all the numbers for the large triangle add them all to get the perimeter.

[tex]\bf \stackrel{\textit{\Large Similar Triangles}}{\cfrac{\stackrel{base}{5}}{\underset{perimeter}{11}}=\cfrac{\stackrel{base}{10}}{\underset{perimeter}{x}}}\implies 5x=110\implies x=\cfrac{110}{5}\implies x=22[/tex]

Answer:

The answer is C , 5^(1/3)

Answer:

[tex]\sin A = \frac{a}{b}[/tex]

Step-by-step explanation:

Given:

We took here a Right Angle Triangle,Δ ABC at angle B as 90°

Side opposite to angle A = a

Side opposite to angle B = b = Hypotenuse

Side opposite to angle C = c

To Find:

Sin A = ?

Solution:

Property of a Sine rule for a Right Angle Triangle.

[tex]\sin A =\frac{\textrm{side opposite to angle A}}{Hypotenuse}\\\sin A =\frac{a}{b}[/tex]

∴ [tex]\sin A = \frac{a}{b}[/tex]

If c is the longest side, then c must be equal to 10 in order to have a right triangle. This is due to the pythagorean theorem

a^2+b^2 = c^2

6^2+8^2 = c^2

36+64 = c^2

100 = c^2

c^2 = 100

sqrt(c^2) = sqrt(100) ... apply square root to both sides

c = sqrt(100)

c = 10

-----------------

So if we know that c = 10, then the side lengths 6,8,c form a right triangle.

Answer:

The equation is [tex]0.3x\leq 180[/tex] and  consuela can drive maximum  600 miles.

Step-by-step explanation:

Given:

Consuela Budget= [tex]\$250[/tex]

Rental Company Charges = [tex]\$10 \ per\ day[/tex]

Additional Cost = 30 cents per mile = $0.3 per miles.

Number of days for vacation = 7

We need to find the number of miles Consuela can drive and still be in budget.

Let number of miles she can drive be [tex]x[/tex]

Rental Company Charges for per day [tex]\times[/tex] number of days + Additional Cost per mile [tex]\times[/tex] Number of miles she can drive sholud be less than or equal to Consuela Budget

Now the equation will be.

[tex]10\times 70 +0.3x \leq 250\\70 +0.3 x\leq 250\\0.3x\leq 250-70\\0.3x\leq 180\\x\leq \frac{180}{0.3}\\\\x\leq 600 \ miles[/tex]

Hence Consuela can drive maximum of 600 miles to stay within her budget.

Answer:

The Proceeds of maturity after 10 years is $1613.4

Step-by-step explanation:

Given as :

The maturity value = $ 6000

The rate applied at 6 % compounded quarterly

The Time period = 4 years

Now,

Amount = Principal × [tex](1+\dfrac{\textrm Rate}{4\times 100})^{\textrm 4\times Time}[/tex]

Or, Amount = 6000  × [tex](1+\dfrac{\textrm 6}{4\times 100})^{\textrm 4\times 4}[/tex]

Or, Amount = 6000 × [tex](1.015)^{16}[/tex]

Or,  Amount = 6000 × 1.2689

∴  Amount = $ 7613.4

So, The proceeds after 10 years = $ 7613.4 - $ 6000 = $ 1613.4

Hence The Proceeds of maturity after 10 years is $1613.4   Answer
