A trapezoid pyramid has a base area of 128 square centimeters. If it’s volume is 10,240 cubic centimeters, what is the height of

White raven [17]

Answer:

The height of the pyramid is $1.875\ cm$

Step-by-step explanation:

we know that

The volume of the trapezoid pyramid is equal to

$V=Bh$

where

B is the area of the trapezoid base

h is the height of the pyramid

we have

$B=128\ cm^{2}$

$V=240\ cm^{3}$

substitute and solve for h

$240=(128)h$

$h=240/(128)=1.875\ cm$

What’s the correct answer for this?

e-lub [12.9K]

Answer:

1) Antonio's statement

2) <A = 123

Step-by-step explanation:

1) Antonio's statement is incorrect. This is because the opposite angles of a quadrilateral add up to 180°. Erin was incorrect because the opposite angles of this quadrilateral are unequal.

2) 2x+7+5x-2 = 180° (opposite angles of quadrilateral)

Now

7x+5 = 180

7x = 175

x = 25

<A = 5x-2

= 5(25)-2

= 125-2

= 123

Michael obtains a 30/8 balloon mortgage to finance $425,500 at 6.55%. How much principal and interest will he have already paid

STALIN [3.7K]

Answer:

$259 532

Step-by-step explanation:

Step 1. Calculate the monthly payments on a 30-year loan.

The formula for the monthly payment (P) on a loan of A dollars that is paid back in equal monthly payments over n months, at an annual interest rate

of r % is

$P = A(\frac{r}{1-(1+r)^{-n}})$

We must express the interest rate on a monthly basis.

i = 6.55 %/yr = 0.545 83 %/mo = 0.005 4583

A = $425 500

n = 360 mo

<em>Calculation: </em>

$P = 425 500(\frac{0.005 4853}{1-(1+0.005 4583)^{-360}})$

$P = \frac{2332.22}{{1- {1.005 4583}}^{-360}}$

$P = \frac{2332.52}{1 – 0.140907}$

$P = \frac{2332.52}{0.859 093}$

P = $2703.46

B. Total Payment (T) after 8 years

T = nP

T = 96 × 2703.46

T = $259 532

Michael will have paid $259 532 at the end of eight years.

Step-by-step explanation:

$( {m}^{15} )( {m}^{3} ) ^ {- 4} \\ = ( {m}^{15} )( {m}^{3 \times - 4} ) \\ = ( {m}^{15} )( {m}^{ - 12} ) \\ = {m}^{15 + ( - 12)} \\ = {m}^{15 - 12} \\ = {m}^{3} \\ {m}^{x} = {m}^{3} \\ x = 3$

If the discriminant of a quadratic equation is equal to -8, which statement describes the roots?

tia_tia [17]

Answer:

There are two complex roots.

Step-by-step explanation:

When the discriminant is a negative number, the parabola will not intersect the x-axis. This means that there are no solutions/two complex solutions.
