Answer:

Ram studied for longer time

Step-by-step explanation:

An hour = 60 minutes

Raj studied for 4/7 of an hour

= 4/7 of 60 minutes

= 4/7 × 60

= (4×60)/7

= 240/7

= 24.29 minutes

ram studied for 5/8 of an hour

= 5/8 of 60 minutes

= 5/8 × 60

= (5×60)/8

= 300/8

= 37.5 minutes

who studied for longer time?

Ram - Raj

= 37.5 - 24.29

= 13.21 minutes

Ram studied for longer time

Ram studied 13.21 minutes longer than Raj

therefore the degree of the following polynomial is 2

Answer:

A

Step-by-step explanation:

Isolate the variable y in each equation

A.

y + 2.9 = 8

To isolate y, subtract both sides by 2.9

y = 5.1

This equation has y = 5.1

Let's check the other equations just to get a better understanding of how to do it

B.

y - 11 = 5.1

To isolate y, add both sides by 11

y = 16.1

This equation does not have y = 5.1

C.

y + 4.2 = 5.2

To isolate y, subtract both sides by 4.2

y = 1

This equation does not have y = 5.1

D.

24 - y = 19.2

To isolate y, subtract both sides by 24

-y = -4.8

To isolate y, divide both sides by -1

y = 4.8

This equation does not have y = 5.1

Answer:

A

Step-by-step explanation:

Y+2.9=8

8-2.9= 5.1

Y=5.1

Answer:

B. 13√3

Step-by-step explanation:

Apply pythagorean theorem:

Thus, we have:

x² = (12√3)² + (5√3)²

x² = 432 + 75

x² = 507

x = √507

x = 13√3

Multiply 1/3 and 9, and 1/3 and 12 first. Or divide 9 and 12 by 3, that also works.

3x+4+4x+6

Now combine like terms.

3x+4x=7x

4+6=10

The final expression is 7x+10

Step-by-step explanation:

The length of QR is required.

The length of QR is 6.71 inches.

From the figure it can be determined that

[tex]RP=NR=3\ \text{inches}[/tex]  (Radius)

[tex]RP=NP=6\ \text{inches}[/tex] (MNPQ is a square)

From the Pythagoras theorem we get

[tex]QR=\sqrt{RP^2+QP^2}\\\Rightarrow QR=\sqrt{3^2+6^2}\\\Rightarrow QR=6.71\ \text{inches}[/tex]

Answer:

x > -1

Step-by-step explanation:

p = (f o g)(x) = log ((x+4)-3)

p = log (x+1)

so that p has a value,

the value of x + 1 mus be greater than 0

x + 1 > 0

x > -1

so the domain is x > -1

Domain = {x | x > -1, x must real number}

Answer:

1 hour

Step-by-step explanation:

It would take that long because they work together, at 4 hours Ryan's 3 are subtracted and the result would be 1 hour. This is because while one of us makes the errors in the first or second paragraph, the other is checking the next and thus they finish faster.

If they worked together they can finish the given task in [tex]\frac{7}{12}[/tex] hours.

Given that, Leeson can proofread a newspaper copy in 4 hours. If Ryan proofreads the same newspaper copy, it takes 3 hours.

We need to find how long would it take if they worked together.

Work Done = Time Taken × Rate of Work. Rate of Work = 1 / Time Taken. Time Taken = 1 / Rate of Work. If a piece of work is done in x number of days, then the work done in one day = 1/x.

Now, the work done by Leeson [tex]=\frac{1}{4}[/tex] and the work done by Ryan [tex]=\frac{1}{3}[/tex]

So, work done by both together [tex]=\frac{1}{4}+\frac{1}{3}=\frac{3+4}{12}=\frac{7}{12}[/tex] hours.

Therefore, if they worked together they can finish the given task in [tex]\frac{7}{12}[/tex] hours.

The function that has a remainder of 18 when divided by ( x-2 ) is
f ( x ) = 2x⁴ + 4x² - 10x - 10

What is a polynomial function?

A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation, etc.

Given data ,

The divisor = ( x - 2 )

The remainder = 18

The function will be f( x ) = 2x⁴ + 4x² - 10x - 10

Step 1 :

Divide f ( x ) by ( x-2 ) = [tex]\frac{2x^4+4x^2-10x-10}{x-2}[/tex]

=

[tex]2x^3+\frac{4x^3+4x^2-10x-10}{x-2}[/tex]

Step 2 :

Divide  [tex]\frac{4x^3+4x^2-10x-10}{x-2}[/tex]

=

[tex]2x^3+4x^2+\frac{12x^2-10x-10}{x-2}[/tex]

Step 3 :

Divide  [tex]\frac{12x^2-10x-10}{x-2}[/tex]

=

[tex]2x^3+4x^2+12x+\frac{14x-10}{x-2}[/tex]

Step 4 :

Divide  [tex]\frac{14x-10}{x-2}[/tex]

=

[tex]2x^3+4x^2+12x+14+\frac{18}{x-2}[/tex]

The remainder is 18 at the end of step 4

Hence , the function that has a remainder of 18 when divided by ( x-2 ) is
f ( x ) = 2x⁴ + 4x² - 10x - 10

Answer:

9/10

Step-by-step explanation:

First, 1 1/2 as a improper fraction is 3/2

Second, 3/2 x 3/5 = 9/10

Third, you need to do 9/10 x 2 since there are two earings which equals 18/10.

Fourth, 18/10 divided by 2 = 9/10 which means that the area of both earrings is 9/10

Answer:

The distance from the ship to the dock is approximately 5.24 miles

Step-by-step explanation:

From the parameters given in the question, we have;

The angle formed between the dock and the lighthouse = 70°

The angle formed between the dock and the lighthouse at the ship = 80°

The distance between dock and the lighthouse = 5 miles (From a similar question online)

By sine rule, we have;

[tex]\dfrac{a}{sin(A)} = \dfrac{b}{sin(B)} = \dfrac{c}{sin(C)}[/tex]

Therefore, we have;

[tex]\dfrac{5}{sin(70^{\circ})} = \dfrac{The \ distance \ from \ the \ ship \ to \ the \ dock}{sin(80^{\circ})}[/tex]

[tex]\therefore The \ distance \ from \ the \ ship \ to \ the \ dock = sin(80^{\circ}) \times \dfrac{5}{sin(70^{\circ})}[/tex]

[tex]sin(80^{\circ}) \times \dfrac{5}{sin(70^{\circ})} \approx 5.24 \ mi[/tex]

Therefore;

The distance from the ship to the dock ≈ 5.24 miles
