What is the price of 8 notebooks and 7 pens if 4 notebooks and 3 pens cost $96, while 2 pens and 2 notebooks cost $54?

Answers

Answer:

$204

Step-by-step explanation:

Create a system of equations where p is the price of a pen and n is the cost of a notebook:

4n + 3p = 96

2n + 2p = 54

Solve by elimination by multiplying the bottom equation by -2:

4n + 3p = 96

-4n - 4p = -108

-p = -12

p = 12

So, a pen costs $12. Plug this in as p into one of the equations, and solve for n:

2n + 2p = 54

2n + 2(12) = 54

2n + 24 = 54

2n = 30

n = 15

So, a notebook costs $15.

Using this, find the price of 8 notebooks:

15(8)

= 120

Find the price of 7 pens:

12(7)

= 84

Add this together:

120 + 84

= 204

So, the price of 8 notebooks and 7 pens is $204

Answers

Answer:

x² - 16

Step-by-step explanation:

Use the FOIL method here where

F = first

O = outer

I = inner

L = last

F = x * x = x²

O = -4 * x = -4x

I = 4 * x = 4x

L = -4 * 4 = -16

Combine the terms to get x² - 16.

Calinda is painting the design on her bedroom wall. The large circle has a diameter of 32 inches. To the nearest square inch, how much paint swill she need for the shared reign on

Answers

Answer:

804 inches

Step-by-step explanation:

Amount of paint she would need is equal to the area of the circle

Area of a circle = πr²

π = 3.14

r = 32/2 = 16

The diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

3.14 x 16² = 804 in

Rotate an isosceles right triangle around a line that contains the triangle's hypotenuse

Answers

Answer:

See attachment 2 for the rotation

Step-by-step explanation:

The question has a missing figure

See attachment 1 for the missing figure of the isosceles right-triangle

Required

Rotate around the hypotenuse

From the attachment, the hypotenuse is along the blue vertical line along the y-axis.

So, when the isosceles triangle is rotated around the hypotenuse, the result of the rotation we get a composite figure that has two congruent solids.

Which is a cone of radius and height equal to half of the hypotenuse

Jamie uses exactly 18 inches of dental floss every time she flosses her teeth. The package of dental floss she just bought contains 27 yards. How many times can Jamie floss her teeth with the amount of floss in this package?

Answers

Answer:

54 times

Step-by-step explanation:

36 inches = 1 yard

Since there are 27 yards, you multiply 36 by 27 = 972

If you use 18 inches each time, you would divide 972 by 18.

972/18= 54

So, Jamie could flow her teeth 54 times.

THE CORRECT ANSWER IS 57 CM³

Explanation:

Let's consider the vertical block first, having height 9 cm, length 1 cm, width 5 cm.

Hence the volume of that block = l.w.h = 9×5×1 = 45 cm³

Coming to the horizontal block, having height 4 cm, width 3cm, & length 1 cm.

Hence the volume of that block will be = 4×3×1 = 12 cm²

The total volume of irregular figure = Volume of vertical block + horizontal block = 45+12 = 57 cm³

Una caja de carton se ha disenado para qu contenga 184cm cubicos. Si su altura es de 10cm, cual es el area de la base?

Answers

Answer:

18.4 cm²

Step-by-step explanation:

Una caja de carton se ha disenado para qu contenga 184cm cubicos. Si su altura es de 10cm, cual es el area de la base?

Volumen = Área de la base × Altura

Área de la base = Volumen / Altura

= 184 cm³ / 10 cm

Área de la base = 18.4 cm²

Por lo tanto, el área de la base es de 18.4 cm².
