Answer:

Rs 816

Step-by-step explanation:

For the above question, the formula to use is given as:

Amount = P( 1 + r/n)^nt

Given, P = 10,000

r = 8% = 0.08

n = 2 = semi annually

t = 1 year

Amount = 10,000( 1 + 0.08/2)^2×1

Amount = 10,000( 1 + 0.04)²

= 10,000(1.04)²

= 10,000(1.0816)

= 10,816

Hence, Interest is calculated as

Amount - Principal

interest = Rs. 10,816 − Rs. 10000

= Rs. 816

Hence, interest paid at the time of maturity is Rs. 816.

Step-by-step explanation:

The solutions to the equation x minus StartFraction 7 Over x EndFraction is equal to 6 is -1 and 7

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

We have equation:

[tex]\rm x-\dfrac{7}{x}=6[/tex]

After simplifying:

[tex]\rm x^2 -7 = 6x\\\\x^2-6x-7=0[/tex]

[tex]\rm x^2 +x-7x-7=0[/tex]

(x + 1)(x - 7) = 0

x = -1 or x = 7

Thus, the solutions to the equation x minus StartFraction 7 Over x EndFraction is equal to 6 is -1 and 7

              2

Step-by-step explanation:

Next time, please share the possible answers.  Thank you.

x^2 + 7x + 44 has a parabolic graph that opens up and never intersects the x-axis.  Thus, it has no real roots.

The coefficients of this polynomial are a = 1, b = 7, c = 44.

The discriminant is b^2 - 4ac, or 7^2 - 4(1)(44) = -127.  As expected, this is negative, confirming that the roots are complex.

The roots are:

      -7 ± i√127

x = -----------------

              2

Answer:

The answer is option A.

p = 0.7(rh + b)

Making h the subject

divide both sides by 0.7

we get

p/0.7 = rh + b

send b to the left side of the equation

p / 0.7 - b = rh

divide both sides by r

we get

( p / 0.7 - b) ÷ r = h

therefore h = ( p / 0.7 - b ) ÷ r

Answer: The area is 24 square units.

Step-by-step explanation:

Things you need to use in this exercise:

Area of a circle = pi*r^2

r is the radius, equal to half the diameter.

Ok, in the image we can see 3 half-circles.

one has a diameter of 8 units: with area A (the left one)

other has a diameter of 6 units: with area B (the bottom one)

and the other has a diameter equal to the hypotenuse of the right triangle: with area C (the white semicircle that also includes the right triangle)

Now, you can think the shaded area as:

The sum of the areas of the half circles A and B, minus the area of the half-circle C, plus the area of the right triangle (because the white triangle is also included in the white semicircle)

So the area is:

A + B - C + area triangle

A = pi*(8/2)^2 = 3.14*4^2 = 50.24

B = pi*(6/2)^2 = 3.14*3^2 = 28.26

the area of the triangle is equal to:

T = 6*8/2 = 24

Now, to obtain the area of the white semicircle ( C) we need the hypotenuse of the triangle, so here we can use the Pythagorean's theorem:

H^2 = 8^2 +6^2

H = √(8^2 + 6^2) = 10

Then:

C = pi*(10/2)^2 = 3.14*5^2 = 78.5

Then the shaded area is:

Area = 50.24 + 28.26 + 24 - 78.5 = 24

Answer:

Answer:

[tex]Goat = 2080IU[/tex]

Step-by-step explanation:

Given

Ratio = 3 : 4

Litre of cow = 1560IU

Required

IU of a litre of goat

The ratio represents ratio of cow milk to goat milk

In other words;

[tex]Cow:Goat = 3 : 4[/tex]

To calculate the number of IU in a litre of goat milk; we substitute Cow with 1650 in the above expression

[tex]Cow:Goat = 3 : 4[/tex]

[tex]1560:Goat = 3 : 4[/tex]

Convert  to fraction

[tex]\frac{1560}{Goat} = \frac{3}{4}[/tex]

Multiply both sides by 4

[tex]4 * \frac{1560}{Goat} = \frac{3}{4} * 4[/tex]

[tex]\frac{4 * 1560}{Goat} = \frac{ 4 * 3}{4}[/tex]

[tex]\frac{6240}{Goat} = 3[/tex]

Multiply both sides by Goat

[tex]Goat * \frac{6240}{Goat} = 3 * Goat[/tex]

[tex]6240 = 3 * Goat[/tex]

Divide both sides by 3

[tex]\frac{6240}{3} = \frac{3 * Goat}{3}[/tex]

[tex]\frac{6240}{3} = \frac{3 * Goat}{3}[/tex]

[tex]2080 = Goat[/tex]

[tex]Goat = 2080[/tex]

Answer:

The distance from the Zoo to the city is 80 km

Step-by-step explanation:

The given information are;

The speed of the tour bus = 78 km/h

The point of passing the tour bus = Half way between the city and the Zoo

The time taken after passing the tour bus when it was still  14 km from the city = 20 minutes = 20/60 hour = 1/3 hour

Therefore, we have that the distance covered by the tour bus in 1/3 hour  = Time ×Speed = 1/3×78 = 26 km

The distance remaining for the tour bus to reach the city = 14 km

The total distance from the time of observation of the tour bus = Half the distance from the city to the Zoo

Also, the total distance from the time of observation of the tour bus = 26 km + 14 km = 40 km

∴ 40 km = Half the distance from the city to the Zoo

Which gives;

The distance from the Zoo to the city = 2 × 40 km = 80 km.

Answer:

1/9

Step-by-step explanation:

1/9 in decimal format is .11111 repeated

Answer:

1/9

Step-by-step explanation:

if you want repeating numbers in decimal form changed to a fraction, put a nines in the denominator. I repeating is  1/9. Another example, 12 repeating is 12/99. However many numbers there are in the numerator, put the same amount in the denominator but all nines. Another example, 108 repeating in a fraction form is 108/999. Three numbers in the numerator, so three 9's in the denominator. Hope this helps! :)

Hey there!

Choice A represents a function, because a function only has one y value for every x value.

Hope this helps :)

Answer:

A

Step-by-step explanation:

In a function, the x value can only go to one y value

B has x=5 going to y = 13 and y = 17

C had x = -3 with y values of 1 and -1

D has x = -4 going to y = 52 and 16

A each input has only one output value

Answer:

The numbers are 11 and 13

Step-by-step explanation:

Let

the first odd whole number=x

Reciprocal=1/x

Second odd whole number=x+2

Reciprocal=1/x+2

The difference

(1/x) - 1/(x+2)=2/143

(x+2)-x / (x)(x+2)=2/143

x+2-x/x(x+2)=2/143

2/x(x+2)=2/143

2(143)=2(x^2+2x)

286=2x^2+4x

2x^2+4x-286=0

x^2+2x-143=0

Solve the quadratic Equation

x=-b +or- √b^2-4ac/2a

a=1

b=2

c=-143

x= -b +or- √b^2-4ac/2a

=-2 +or- √(2)^2-(4)(1)(-143) / 2(1)

= -2 +or- √4-(-572) / 2

= -2 +or- √4+572/2

= -2 +or- √576/2

= -2 +or- 24/2

x= -2+24/2

= 22/2

=11

Or

x= -2-24/2

= -26/2

= -13

Taking the positive value

x=11

The second odd whole number=x+2

=11+2

=13

Answer:

Step-by-step explanation:

A.) 600 x 20 = 12,000

    120 x 27 = 3,240

     12,000 + 3,240 = 15,240

B.) 600 x 13 = 7,800

     120 x 20 = 2,400

     7,800 + 2,400 = 10,200

C.) 600 x 18 = 10,800

    120 x 25 = 3,000

    10,800 + 3,000 = 13,800

D.) 600 x 11 = 6,600

     120 x 18 = 2,160

     6,600 + 2,160 = 8,760

Answer:

Altogether they lost 150 pennies.

Step-by-step explanation:

X = Dante's pennies

Y = Mia's pennies

X + Y = 350                                       1/2 X = 2/3 Y

                                                                X = 4/3 Y

4/3 Y + Y = 350

7/3 Y = 350

Y = 350 * 3/7

Y = 50 * 3

Y = 150

X + 150 = 350

X = 200

                                                     1/2 * 200 = 2/3 * 150

                                                       100 .      =   100

1/2 * 200 = 100 -> Dante lost 100 pennies

1/3 * 150 = 50 -> Mia lost 50 pennies

Altogether they lost 150 pennies.

Answer B (The cost of fabric compared to its length)

Step-by-step explanation:

The cost of fabric is directly proportional to the length of fabric one is buying. That constant of proportionality is telling you that there is a constant rate of change in units of cost per length.

The other options are much more randomly varying.

The side lengths 8 cm, 6 cm, and 10 cm that can form a right triangle option (B), (C), and (D) are correct.

It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.

We know that Pythagoras theorem:

[tex]\rm Hypotenuse^2 = Perpendicular^2 + Base^2[/tex]

10² = 8² + 6² = 64+36 = 100

Thus, the side lengths 8 cm, 6 cm, and 10 cm that can form a right triangle option (B), (C), and (D) are correct.

Answer:

P=26

Step-by-step explanation:

Answer:

Step-by-step explanation:

Begin with the fact that the area of a rectangle is A = L * W.  We know that the area is 42 and the length is 7, therefore, we can sub those values into the area formula to solve for the width.

42 = 7 * W so

w = 6 mm.

The perimeter formula is P = 2L + 2W, and now we know L and W. So

P = 2(7) + 2(6)

P = 14 + 12

P = 26
