Answer:

The possible value of X are;

15, 30, 45, 60 etc

Step-by-step explanation:

The parameters given are

Number of chocolates Tanmay had = X

Number of chocolates Tanmay gave to Akash = 1/3 × X

Number of chocolates Tanmay gave to Sharad = 1/5 × X

Whereby 3 and 5 are factors of X, therefore;

3 × 5 = 15 is the lowest single factor of X

The possible values of X starting from the lowest factor are given as follows;

15 × 1 = 15

15 × 2 = 30

15 × 3 = 45

15 × 4 = 60

Hence, the possible value of X are the arithmetic progression a + (n - 1)×d

Where:

a = 15

n = 1, 2, 3, 4, ...

d = 15

Which includes;

15, 30, 45, 60

Answer:

10 miles

Step-by-step explanation:

Given: Bike goes 8 miles south and then 6 miles east

To find: distance between the final point and the starting point

Solution:

Pythagoras Theorem

In a right angled triangle, square of hypotenuse is equal to the sum of squares of the two sides.

In ΔOAB,

[tex]OB^2=OA^2+AB^2[/tex]

Put [tex]OA=8\,,\,AB=6[/tex]

[tex]OB^2=8^2+6^2=64+36=100[/tex]

Take square root on both sides.

[tex]OB=\sqrt{100}=10\,\,miles[/tex]

So, distance between the final point and the starting point is 10 miles

Answer:

10 miles

Step-by-step explanation:

7a-9=12

Add 9 to both sides:

7a= 21

Divide both sides by7

A= 3

Answer:

The value of a is 3.

Step-by-step explanation:

First, you have to add 9 to both sides to eliminate -9 on the left side :

[tex]7a - 9 = 12[/tex]

[tex]7a - 9 + 9 = 12 + 9[/tex]

[tex]7a = 21[/tex]

In order, to find a, you have to divide it by 7 :

[tex]a = 21 \div 7[/tex]

[tex]a = 3[/tex]

Answer:

x,y =  ( 3 17/21  ,  10/21)

Step-by-step explanation:

Painting the room = 1    whole job

Morgan rate =   1/10

Sophia rate  =  1/4

Rate x time = 1    job

1/10 x   + 1/4 y  = 1/2      and

1/10 y  +  1/4 x  = 1          solve for x,y

Multiply the top equation by - 2.5

(-2.5)/10 x   - (2.5/4) y = -1.25    

-1/4 x  - 5/8 y =  -1 .25

 and add to the second equation to get

1/10 y  - 5/8 y = -.25    solve for y

4/40 y - 25/40 y = -.25

-21/40 y = - .25

y =  10/21  hr                           Substitute this into one of the original equations to find 'x'

1/10  (10/21) + 1/4 x = 1

1/21 + 1/4 x = 1

1/4 x = 20/21

x = 80/21                                         x,y =  ( 3 17/21  ,  10/21)

Answer:

The cashier received 100 envelopes

Step-by-step explanation:

let the number of stamps bought be x.

Cashier will receive 1/3 *x = x/3

Secretary will receive = 1/5 * x = x/5

Now we are told that the secretary received 40 fewer.

This means that the difference between the amounts they received is 40

Mathematically;

x/3 - x/5 = 40

2x/15 = 40

x = (15 * 40)/2 = 600/2 = 300

The cashier received x/3 = 300/3 = 100

Answer:

Cashier received 100 stamps

Step-by-step explanation:

1/3 to cashier

1/5 to secretary

Total stamps=x

Cashier=(1/3)x

Secretary=(1/5)x

Secretary received 40 fewer stamps than the cashier

Difference between cashier and secretary share=40

1/3x-1/5x=40

(2/15)x=40

40×15=2x

600=2x

x=300

Cashier=(1/3)x

=(1/3)300

Step-by-step explanation:

Answer:

$2800

Step-by-step explanation:

First divide $4800 by 3 which will give you $1600 which is the price for 2 cars and 1 truck.

= [tex]\frac{4800}{3} = $1600[/tex]

Next, subtract the $1600, which is the price of 2 cars and 1 truck  from $4600, which is the price of 8 cars and 1 truck giving you the price of 6 cars.

$4600 - $1600 = $3000

Now divide the $3000, the price of six cars, by three to get the price of 2 cars.

[tex]\frac{3000}{3} = $1000[/tex]

Lastly, multiply the $1000 by 2 to get the price of 4 cars. Then subtract this $2000, the price of 4 cars from the $4800, the price of 6 cars and three trucks to give you the price of 2 cars and 3 trucks.

$4800 - $1000 = $2800

Answer: 1/6

Step-by-step explanation:

Two fair dice is rolled once,

To win sum of the two dice should equal 10 or more

To get a sum equal 10 or more,

The total possible outcome when two dice is rolled once = 6^2 = 36

Sample space is attached below

Total required outcome to win (probability of having a sum of 10 or more)

n(sum of 10 or more) = 6

Therefore, probability of winning equals :

P(winning) = (Total required outcome / Total possible outcomes)

P(winning) = n(sum of 10 or more) / total possible outcomes

P(winning) = 6/36 = 1/6

Answer:

17 cm²

Step-by-step explanation:

First I cut this figure into 2 rectangles. One big and small one. (the big one is on top of the small rectangle).

For the big rectangle, I multiplied its length by its width.

The area of the big rectangle: 3cm * 5cm = 15cm²

For the smaller rectangle, I also multiplied its length and width.

The area of the small rectangle: 1cm * 2 cm = 2cm²

Add up its areas: 15+2

Answer:

Just put the values of x and y

x = 1

y = -2

2x – y = p

2(1) - (- 2) = p

p = 4

Answer:

The value of p is 4.

Step-by-step explanation:

In order to find p, you have to substitute the value of x and y into the linear equation :

[tex]2x - y = p[/tex]

[tex]let \: x = 1 \\ let \: y = - 2[/tex]

[tex]2(1) - ( - 2) = p[/tex]

[tex]2 + 2 = p[/tex]

[tex]p = 4[/tex]

Answer:

120

Step-by-step explanation:

The measure of the arc QR⏜ intercepted by the inscribed ∠QPR is given.

According to the Inscribed Angle Theorem, the measure of the inscribed angle is equal to one-half the measure of the arc.

m∠QPR=12mQR⏜

Substitute 60° for mQR⏜.

m∠QPR=12(60°)

Simplify.

m∠QPR=30°

The figure shows the same circle as in the beginning of the task. Triangle P R S is highlighted in red. Angle S P R measures 30 degrees.

It is given that m∠SRP=30°. Use the Triangle Sum Theorem to find the measure of the unknown ∠PSR.

m∠SRP+m∠SPR+m∠PSR=180°

Substitute the known values.

30°+30°+m∠PSR=180°

Simplify.

60°+m∠PSR=180°

Subtract 60° from both sides.

m∠PSR=120°

Therefore, m∠PSR=120°.

Step-by-step explanation:

[tex]\frac{10-\sqrt{18}}{\sqrt{2}}[/tex]

Simplify the square root of 18.

[tex]\frac{10-3\sqrt{2}}{\sqrt{2}}[/tex]

Rationalize the fraction.

[tex]\frac{\left(10-3\sqrt{2}\right)\sqrt{2}}{\sqrt{2}\sqrt{2}}[/tex]

[tex]\frac{2\left(5\sqrt{2}-3\right)}{2}[/tex]

[tex]5\sqrt{2}-3[/tex]

Rewrite the answer in the form a+b√2.

[tex]-3 + 5\sqrt{2}[/tex]

The given form of expression a + b √2 where a and b are integers then the values of a and b are -3 and 5.

factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.

[tex]\frac{10 -\sqrt18} {\sqrt 2}= a + b \sqrt 2[/tex]

Simplify the square root of 18 then Rationalize the fraction,

[tex]\\\frac{10 -3\sqrt2} {\sqrt 2}\\\\\frac{(10 -3\sqrt2) \times \sqrt{2} } {\sqrt 2 \sqrt 2}\\\\\frac{ 2(5\sqrt2 -3) } { 2}\\\\(5\sqrt2 -3)[/tex]

Thus, the values of a and b are -3 and 5.
