The interest is $8.77 owed in the amount of $900 for 9 months more than for 6 months.

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, The rate of interest is in percentage r% and is to be written as r/100

To  determine interest on the amount of $900 for 9 months

Here P = $900, R =  2.9% = 2.9/100, and T = 9/12 year

Interest  = P × R × T

Interest  = 900 × 2.9/100 × 9/12

Interest  = $19.57

To  determine interest on the amount of $900 for 6 months

Here P = $900, R =  2.4% = 2.4/100, and T = 6/12 year

Interest  = P × R × T

Interest  = 900 × 2.4/100 × 6/12

Interest  = $10.80

The difference of interest is owed on $900 for 9 months then for 6 months: $19.57 - $10.80 = $8.77

Therefore, the interest is $8.77 owed in the amount of $900 for 9 months more than for 6 months.

Answer:

The answer is D

Step-by-step explanation:

To find the height the ladder reaches up the wall, set up a proportion using similar triangles and Catie's height as the ladder's height. The estimate for the ladder's height up the wall is 6.8 feet.

Given information:

To find the height the ladder reaches up the wall, we can set up a proportion using similar triangles. Catie's height can be considered as the ladder's height, and the distance on the wall can be related to the ladder's base and height.

Using the information provided and performing the calculations, the estimate for the height the ladder reaches up the wall would be approximately **6.8 feet** to the nearest tenth of a foot.

The value of a in the diagram is 144°.

The correct option is B.

An open, flat object with four straight sides and one set of parallel sides is referred to as a trapezoid or trapezium. A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases.

Given:

A trapezium has parallel bases and that one of its characteristics is that the two angles on a single side are supplementary, meaning that the total of the angles on two neighboring sides is 180°.

So,

∠a = 180 - 36

∠a = 144

∠b = 180 - 113

∠b = 67

Therefore, the value of a is 144°.

Final answer:

By creating and solving a system of equations based on the given information, we find that there are 10 blue marbles and 8 red marbles.

Explanation:

To solve this problem, we set up two equations based on the information given:

3 times the number of blue marbles (3B) exceeds 2 times the number of red marbles (2R) by 18: 3B - 2R = 18.

5 times the number of blue marbles (5B) is 2 less than 6 times the number of red marbles (6R): 5B = 6R - 2.

Now, we can solve these equations using substitution or elimination. Using substitution, solve the second equation for B:

B = ⅜(6R - 2)

Then substitute this expression for B in the first equation:

3(⅜(6R - 2)) - 2R = 18

Solve for R:

R = 8

Now substitute R back into the equation for B:

B = ⅜(6(8) - 2) = 10

Thus, there are 10 blue marbles and 8 red marbles.

Solution:

we are given with [tex] (a + b)(a^2 - ab + b^2) [/tex]

we have been asked to find the representation of the given factor as a Sum.

As we know that

[tex] (a^3+b^3)= (a + b)(a^2 - ab + b^2) [/tex]

Because

[tex] (a + b)(a^2 - ab + b^2)=a(a^2 - ab + b^2)+b(a^2 - ab + b^2)\\
\\
(a + b)(a^2 - ab + b^2)=a^3-a^2b+ab^2+ba^2-ab^2+b^3\\
\\
(a + b)(a^2 - ab + b^2)=a^3+b^3\\ [/tex]

The area of the larger quadrilateral is found by using the scale factor derived from the ratio of the perimeters of the similar quadrilaterals, which comes out to 150 cm².

The question involves finding the area of a larger quadrilateral given the perimeters of two similar quadrilaterals and the area of the smaller one. In similar figures, the ratio of their areas is the square of the ratio of their corresponding linear dimensions, such as side lengths or perimeters in this case. Since the perimeters are 48 cm and 60 cm, the ratio of the perimeters (also the scale factor) is 48/60, or 4/5. Consequently, the ratio of the areas is the square of the scale factor, which is (4/5)² or 16/25. Knowing the area of the smaller quadrilateral is 96 cm², we find the area of the larger quadrilateral by dividing the area of the smaller by the scale factor squared and then multiplying by the larger scale factor squared. This gives us (96 / (16/25)) cm² = (96 * 25/16) cm² = 150 cm².

So, the area of the larger quadrilateral is 150 cm².
