Answer:

Step-by-step explanation:

Remark

It's a right angle triangle. I feel for 17 points, I should be telling you more.

Surface Area

The two faces are triangles. Their area = 1.5 * 2 / 2= 1.5

What I have you is the area of 1 triangle. There are 2 so 2*2.5 = 3

======================

The height of the prism = 10 meters.

The Area of that face = L * w = 10 * 2.5

Area of that face = 25 m^2

Area of the rectangle containing 1.5 as the width = 1.5 * 10 = 15

Area of the rectangle containing 2 as the width = 2  * 10 = 20

The Total Surface Area = 20 + 15 + 25 + 5 = 65 m^2

Volume

Volume = Area of 1 triangle * height

Volume = 1.5 * 10 = 15 m^3

bazaltina [42]
Substitution is best to use one one or both equations is already solved for one of the variables. Elimitation can be use if all variables have a coefficient other than 1.

What is the explicit formula for this sequence? 2,10,50,250,1250<br>​
Valentin [98]

Answer:

a_n = 2(5)^{n-1}

Step-by-step explanation:

Explicit Geometric Formula: a_n = a_1r^{n-1}

a₁ is 1st term

<em>r</em> is common ratio

<em>n</em> is term number

Step 1: Find common ratio <em>r</em>

r = 10/2 = 5

Step 2: Plug variables into formula

a_n = 2(5)^{n-1}

Justin spends $21.75 on 6 rides and three sodas for his friends. Jerry spends $39.50 on 10 rides and 6 sodas for his friends. Ho
SIZIF [17.4K]
R = rides
S = sodas

6R + 3S = $21.75 —> -12R - 6S = -43.5
10R + 6S = $39.50–>10R + 6S = 39.5

Multiplying Justin’s whole equation by -2 will bring out the 6S’, so we can focus on the cost of one ride.

-2R = -4
Divide both sides by -2
So for one ride, it would cost $2.

To find the cost for one soda, we plug in the cost for a ride.

6(2) + 3S = $21.75
12 + 3S = $21.75
3S = $9.75
So for one soda, it would cost $3.25.
