Use the net to compute the surface area of the three-dimensional figure. A) 210 units B) 225 units C) 240 units D) 280 units

11111nata11111 [884]

The answer would most commonly be C only because a square is 360 degrees and the surface area would be a 6th of that which is 60 then i multiplied it by 4 because of the four corners signaling the height and or length of the 2D figure square which gives me C.

Emily sells erasers for $2 per package and pencils for $5 per package. she sells 220 total packages and earns $695. find the num

Sophie [7]

Given :

Emily sells erasers for $2 per package and pencils for $5 per package. she sells 220 total packages and earns $695.

To Find :

The number of packages of erasers and pencils that were sold .

Solution :

Let, number of erasers are x and pencils are y.

So, x + y = 220 ....1

Also, 2x + 5y = 695 ....2

Solving equation 1 and 2, we get :

$2(220-y)+5y = 695\\\\440 - 2y + 5y = 695\\\\3y = 255\\\\y=85$

x = 220 - 85 = 135

Therefore, the number of packages of erasers and pencils that were sold are 135 and 85 respectively.

Hence, this is the required solution.

A small radio transmitter broadcasts in a 29 mile radius. If you drive along a straight line from a city 32 miles north of the t

hram777 [196]

Answer: He will pick up a signal from the transmitter 29.43 miles of the drive.

Step-by-step explanation:

Since we have given that

Radius = 29 mile

So, equation of circle would be

$x^2+y^2=29^2=841$

There is a straight line from a city 32 miles north i.e. (0,32) to a second city 40 miles east of the transmitter i.e. (40,0)

So, equation of line would be

$y-32=\dfrac{0-32}{40-0}(x-0)\\\\y-32=\dfrac{-32}{40}x\\\\y-32=-0.8x\\\\y+0.8x=32\\\\y=32-0.8x$

So, we will put this value in the equation of circle.

$x^2+(32-0.8x)^2=841\\\\x^2+1024+0.64x^2-51.2x=841\\\\1.64x^2-51.2x=841-1024\\\\1.64x^2-51.2x=-183\\\\1.64x^2-51.2x+183=0$

So, x= 4.12 and x = 27.1

So, y = 28.7, y = 10.32

So, distance between them would be

$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\=\sqrt{(27.1-4.12)^2+(28.7-10.32)^2}\\\\=29.43$

Hence, he will pick up a signal from the transmitter 29.43 miles of the drive.

Exactly 640 acres are in one square mile. how many square meters are in 2.2 acres

Tasya [4]

640 acres = 1 square mile

So we can say 1 acres = $\frac{1}{640}$ square mile

So in 2.2 acres = $2.2 * \frac{1}{640}$ square mile

= 0.0034375 square mile

In general one mile = 1609.344 meters

So one square mile = 1609.344 * 1609.344 square meter

= 2589988 square meter

So 0.0034375 square mile = 0.0034375 * 2589988
= 8903.08375 square meter.
