Answer:

8:12

Step-by-step explanation:
The heights of both the pyramids are stated in the question so...
Pyramid A height: 8
Pyramid B height: 12

The ratio is (pyramid A : pyramid B) so our final answer should be...
8:12

4x + 6 + 5x + 3 = 90

9x +9 = 90

( Subtract 9 from 9 and 90 )

9x = 81

( Divide 9x and 81 by 9 )

x = 9

Hope this helps.

Step-by-step explanation:

From the question above one can put down an expression as;

(5/7 × -13/25) ÷ (4/15 + (-7/50))

-13/35 ÷ 19/150

-13/35 × 150/19

-390/133

Answer: 412.5cm cubed

Step-by-step explanation:

Volume of a prism: area of base ( in this case it’s the triangle) times the height

First: half x 90 x 120 = 165

Then times the height

So, 164 x 2.5 = 412.5

The volume of the given pyramid will be 1.35m³.

Design or construction with a base that is a polygon and sides that are three or more triangles that come together at the top.

A pyramid is a 3D shape where 3 triangle comes and meet in such a way that the base side creates a triangle.

The volume of a pyramid is given by

Volume = (1/3)base²×height.

Volume = area of cross-section × length

Given,

Area of cross-section = area of the base (triangle)

Since the area of the triangle = (1/2)base×height

So,

Area of cross-section = (1/2)1.20×0.90 = 0.54 m²

So,

Volume of pyramid = 0.54 × 2.5 = 1.35 m³.

Hence " The volume of the given pyramid will be 1.35m³".

Answer:

  about 14 months

Step-by-step explanation:

Questions regarding loan payments, values, interest amounts, number of payments, and so on, are conveniently answered by the financial formulas available in many apps, calculators, and spreadsheets. Here, we want to solve for the number of payments.

__

The time-value-of-money app on a TI-84 calculator tells us the number of monthly payments is 13.98. It will take about 14 months to pay off the credit card balance.

__

Alternate solutions

You can also use a graphing calculator to find the time value needed in the amortization formula that corresponds to a monthly payment amount of $300 on a loan of $3850 at 13.99% interest compounded 12 times per year. This is shown in the second attachment.

The algebraic solution is a little messy, and involves logarithms, but you can solve it that way, too.

  A = P(r/n)/(1 -(1 +r/n)^(-nt))

gives the monthly payment A on a loan of principal P at annual rate r compounded n times per year for t years. We want to find the value of nt for P=3850, A=300, r=0.1399, n=12.

Putting in the numbers, we get ...

  300 = 3850(0.1399/12)/(1 -(1 +0.1399/12)^(-nt))

  (1.011658333...)^(-nt) = 0.8503847222... . . . . isolate nt term

  nt = -log(0.8503857222...)/log(1.011658333...) ≈ 13.982213...

Answer:

See below

Step-by-step explanation:

Since [tex]cos(\frac{\pi}{2})=0[/tex], the denominator will be 0, and the result would be indeterminate.

Do not read on if you do not understand Calculus

However, notice that [tex]\lim_{x \to \frac{\pi}{2}} \frac{sin(2x)}{cos(x)}=2[/tex] by L'Hopital's Rule:

[tex]\lim_{x \to \frac{\pi}{2}} \frac{sin(2x)}{cos(x)}\\\\\frac{2cos(2x)}{-sin(x)}\\ \\\frac{2cos(2(\frac{\pi}{2}))}{-sin(\frac{\pi}{2} )}\\\\\frac{2cos(\pi)}{-1}\\ \\\frac{-2}{-1}\\ \\2[/tex]

Answer:

3.75 or 3 3/4

Step-by-step explanation

Ok the denominators aren't the same so were going to make them the same by them changing into the same number.

we can do thins by timesing 5 by 4=20 and 4 timesing by 5=20

So now that the denominators are the same we have to times 1 by 4 since it denominator was times by same thing with 3 except that only get times by 5.

1 x 4=4 and 3 x 5=15 so now our two fractions are 15/20 and 4/20

15 divided by 4=3.75 and there's our answer.

we get the .75 because it is 3 more so 3 4 x3 =12 that's where we get 3 and then there is 3 left and 3/4 of and 3/4=0.75 and then you combined them to make 3.75.

Answer:

  $1,500,257.38

Step-by-step explanation:

The balloon payment will be the balance on the loan after 8 years worth of payments have been made. The normal payment amount is the value calculated for a 25-year loan. A spreadsheet, financial calculator, or app can simplify this for you. In the attached, we have used the financial functions available on a TI-84 calculator.

The normal monthly payment will be $13,120.94.

After 8 years, the remaining balance will be $1,500,257.38. This is the size of the balloon payment.

Hey there!

=> y= 16x^2 + 64 +5

Let's obtain a formula for x

=> y= 16x^2 + 64 +5

=> y=16x^2+69

=> y - 69 = 16x^2

=> y - 69/16 = x^2

=> y - 4.3125 = x^2

=> x = √y - 4.3125

=> x = y - 2.08
