Answer:

Perimeter of base: 50 cm

Height: 30 cm

Base area: 60 cm

Volume: 21,600 cm

Surface area: I am sorry I forget how to do surface area, but I hope everything else helps.

Step-by-step explanation:

perimeter of base: 50 cm

13+13=26+24=50

Height: 30 cm

already shows height.

Base area: 60 cm

1) 24/2=12 2) 5*12=60

Volume: 21,600 cm

Length*Base*height/2=24*60*30=43,200/2=21,600

surface area:

Sorry I forget how to do surface area.

Veronica is self employed. In one year, Veronica generates a gross income of $65,500. When calculating her taxes, Veronica is al

butalik [34]

Answer:

$44,850

Step-by-step explanation:

Gross income is $65,500

Allowable deductions are $2,500

Operating income is $65,500-$2,500=$63,000

From the given tax structure, Veronia will pay 15% for the first $25,000 then 30% for $63,000-$25,000=$38,000

Tax will be (0.15*$25,000)+(0.3*$38,000)=$15,150

Remaining expenses will be $5,500-$2,500=$3,000

Income after tax will be $63,000-$15,150=$47,850

Net income=$47,850-$3,000=$44,850

Ans=$44,850

tester [92]

Answer:

En el curso anterior había 430 alumnos.

Step-by-step explanation:

El curso tiene 473 alumnos. Nos dicen que respecto al curso anterior se ha producido un aumento de inscripciones del 10 %. Entonces, siendo x la cantidad de alumnos que había en el curso anterior, se puede plantear la ecuación:

x + 0.1*x= 473

Resolviendo se obtiene:

1.1*x=473

x= 473 ÷1.1

x= 430

En el curso anterior había 430 alumnos.

Given =

Two similar pyramid have base area of 12.2 cm² and 16 cm².

surface area of the larger pyramid = 56 cm²

find out the surface area of the smaller pyramid

To proof =

Let us assume that the surface area of the smaller pyramid be x.

as surface area of the larger pyramid is 56 cm²

Two similar pyramid have base area of 12.2 cm² and 16 cm².

by using ratio and proportion

we have

ratio of the base area of the pyramids : ratio of the surface area of the pyramids

$\frac{12.2}{16} : \frac{x}{56}$

x = 12.2 ×56× $\frac{1}{16}$

by solvingthe above terms

we get

x =42.7cm²

Hence the surface area of the smaller pyramid be 42.7cm²

Hence proved

Answer:

C. x^5/2 + 6x^3/2 + 1.

Step-by-step explanation:

(x^3 + 6x^2 + x^1/2) / x^1/2

= x^(3 - 1/2) + 6 x(2-1/2) + 1

= x^5/2 + 6x^3/2 + 1.
