Answer:

144 in^2

Step-by-step explanation:

There are four triangular sides to this square pyramid.  According to the area-of-a-triangle formula, A = (1/2)(b)(h), which here is A = (1/2)(8 in)(5 in) = 20 in^2.

Thus, the total lateral (side) area is 4(20 in^2) = 80 in^2.

The area of the bottom is (8 in)^2, or 64 in^2.

Thus, the total surface area is 80 in^2 + 64 in^2, or 144 in^2.

Can someone show me how to do this? I’m not sure how to do this
Allushta [10]

Answer: Slope means the gradient. So find the equation of the line first then graph the points on the graph.

Step-by-step explanation:

y=mx+c                 *We want m*

m=(y2-y1)/(x2-x1)

m=(0-1)/(6-3)

m=-1/3

y=-1/3x+2          *(0,2) co-ordinate means it's the y-intercept=c*

I think the slope is -1/3 and then just plt the points on the graph manually.

M x+ B = y solve for B <br><br><br> A x+ B y = C solve for x <br><br><br> Bh/2 = A, solve for h
quester [9]

Step-by-step explanation:

Mx+B=y

B=y-Mx

Ax+By=C

Ax=C-By

Ax/A=C-By/A

x=C-By/A

Bh/2=A

2 x Bh/2=A x 2

Bh=2A

Bh/B=2A/B

h=2A/B

Question: What is the solution to the equation \bold{x\cdot \:2=9x+6}

Answer: \boxed{\bold{x=-\frac{6}{7}}}

Explanation: \downarrow{\downarrow{\downarrow{}}}

[ Step One] Subtract 9x From Both Sides Of Equation

\bold{x\cdot \:2-9x=9x+6-9x}

[ Step Two ] Simplify Equation

\bold{-7x=6}

[ Step Three ] Divide Both Sides By -7

\bold{\frac{-7x}{-7}=\frac{6}{-7}}

[ Step Four ] Simplify

\bold{x=-\frac{6}{7}}

vagabundo [1.1K]
This solution only needs proper understanding of the word problem and identification of variables.
Let x = number of hours rental of the canoe

It costs $5 per hour for a canoe. However, for every rental of one canoe, there is a deposit of $15 regardless.
The expression is then 5x + 15.

This expression will solve how much it costs in total to rent one canoe for x hours.
