Answer:

[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]

Step-by-step explanation:

Given the following data;

Present value, P = $300

Interest rate, r = 8%

Number of times, n = 1/4

Note: Future value = 2 * P = 2*300 = $600

Compound interest is generally calculated based on the interest rate on a loan, principal and the accumulated interest gained from previous periods. This interest is compounded for a certain number of times such as daily, weekly, quarterly or annually.

To find how long she would have to invest her money in order to double it, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Answer:

Number of tile need = 300 tiles

Step-by-step explanation:

Given:

Dimensions of floor = 3 m by 4 m

Perimeter of square tile = 80 cm

Find:

Number of tile need

Computation:

Perimeter of square tile = 4(Side)

80 = 4(Side of tile)

Side of tile = 80 / 4

Side of tile = 20 cm

Side of tile = 0.2 meter

Area of tile = 0.2 x 0.2

Area of tile = 0.04

Area of floor = 3 x 4

Side of tile = 12 square meter

Number of tile need = 12 / 0.04

Number of tile need = 300 tiles

Answer:

[tex]\frac{8-\sqrt{6} }{2}[/tex]

Step-by-step explanation:

To rationalize the denominator, we need to multiply both the numerator and denominator by the conjugate of the denominator, which in this is 2 - √6.

We can write the expression:

[tex]\frac{3\sqrt{6}+5 }{2+\sqrt{6}} *\frac{2-\sqrt{6}}{2-\sqrt{6} }[/tex]

We can use the special product of the difference of squares to simplify the denominator:

[tex](2 + \sqrt{6})(2-\sqrt{6}) = 2^2 - (\sqrt{6})^2 =4 - 6 = -2[/tex]

We can use distributive for the numerator:

[tex](3\sqrt{6}+5)(2-\sqrt{6})=6\sqrt{6} -18+ 10-5\sqrt{6} =\sqrt{6} -8[/tex]

Now we can rewrite the fraction:

[tex]\frac{\sqrt{6}-8 }{-2} =\frac{8-\sqrt{6} }{2}[/tex]

Answer:

V = π r 2h

Step-by-step explanation:

The solution is, the volume of the cylinder in cubic centimeters

V = π(3.5)2h.

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

The volume of a cylinder is given by the equation:

V = π(R)^^2*h

where π = 3.14, R is the radius and h is the height.

If in the image we see that the radius is 7, then the correct option is D.

If in the image we shee that the DIAMETER is 7 (a linear that goes from end to end of the circle and goes trough the middle) then we know that the radius is half of the diameter, 7/2 = 3.5

in this case he correct option is C.

Hence, The solution is, the volume of the cylinder in cubic centimeters

V = π(3.5)2h.

Given :

A man 1.30 m tall is on a top of a building. He observed a car on the road at an angle of 60 degrees if the building is 30 m high.

To Find :

How far is the car from the building.

Solution :

Let, distance between car and the building is x m.

So,

[tex]tan \ \theta = \dfrac{height\ of\ building + height\ of\ man}{distance \ between \ car \ and \ building}\\\\tan \ 60^o = \dfrac{30+1.3}{x}\\\\x = \dfrac{31.3}{1.73}\ m\\\\x = 18.09\ m[/tex]

=======================================================

Explanation:

A) This statement is true, so we can rule it out. A rhombus by definition has four sides the same length. Think of a square but the sides can be slanted or the angles could be something different from 90 degrees.

B) This statement is true. The opposite sides of a rhombus are always parallel. Any rhombus is always a parallelogram, but not the other way around.

C) False. This is the answer. We could have a square, and in which case we have four congruent angles. But we could slant the sides and have the angles be something else. All that matters is that all four sides are the same length.

D) True. Any rhombus is a parallelogram as mentioned in part B. However, some parallelograms are not a rhombus. Consider any rectangle in which the length and width are not the same. The sides are parallel, but we don't have all four sides the same length.

The white Christmas tree is 7.55m

Green Christmas tree is twice as tall as white Christmas tree: 7.55 * 2 = 15.1m

High golden Christmas tree: 15.1m - 0.454m = 14.646m

The total height of 3 Christmas trees is: 7.55m + 15.1m + 14.646m = 37.296m

Since this bakery sells 12 gourmet orange zest cupcakes for $36.00, all the statements that are true include the following:

A. $3.00/1 is a unit rate for the cost per cupcake.

B. Using the same rate, the bakery can sell 2 dozen cupcakes for $72.00.

C. 36/12 represents the ratio of $36.00 for 12 cupcakes.

First of all, we would determine the unit rate for the cost per cupcake by using the following mathematical expression;

Unit rate = Cost of cupcake/number of cupcakes

Substituting the given parameters into the unit rate formula, we have the following;

Unit rate = $36.00/12

Unit rate = $3.00.

This ultimately implies that, the unit rate for the cost per cupcake is equal to $3.00.

Note: 1 dozen is equal to 12 pieces.

For the cost of 2 dozen cupcakes, we have the following:

Cost of 2 dozen cupcakes = 12 × 2 × 3

Cost of 2 dozen cupcakes = $72.00.

For the cost of 8 cupcakes, we have the following:

Cost of 8 cupcakes = 8 × 3

Cost of 8 cupcakes = $24.00.

For the cost of 6 cupcakes, we have the following:

Cost of 6 cupcakes = 6 × 3

Cost of 6 cupcakes = $18.00.

Step-by-step explanation:

The value of the probability P(A or B) is 0.77

The given parameters are:

P(A) = 0.64

P(B) = 0.25

P(A and B) = 0.12

The probability is then calculated as

P(A or B) = P(A) + P(B) - P(A and B)

Substitute the known values in the above equation

P(A or B) = 0.64 + 0.25 - 0.12

Evaluate the like terms

P(A or B) = 0.77

Hence, the value of the probability P(A or B) is 0.77

Answer:

D.five more than the quotient of 6 and a number,

Step-by-step explanation:

To evaluate the the phrase written as :

6/r+5

Here, there is no bracket to make any distinction, hence using the BODMAS mode of evaluation, we deal with the division first before the sum. Hence we interpr te the equation as :

6 / r = quotient ; then, 5 is added to the quotient obtained from the divison of 6 by r.

Answer:

83,000

Step-by-step explanation:

Thousand = 1,000s place

1,000s place of 83,243 is the 3 (3,000)

The number right before 3 is the 2 (200)

2 is closer to zero than 10 so it rounds down

83,243 then becomes 83,000 since the other numbers before the (2) round down with it.
