Answer: 200 in squared
Step-by-step explanation:
Each of the triangles in this picture are the same. You can tell because it's a square, and because of the dotted line.
Take the white triangle and substitute it for one of the black ones. Now, you have this.
Now, just do 10 * 20
= 200

How do I complete this chart?
Answer:
Step-by-step explanation:
You would first have to plug in for x, (which is already given). After plugging in for x, you would need to solve the equation to get y.
Once you have both x and y, you will have your (x,y)
For example: (given x value = -5)
[tex]f(x) = -|x - 5| -4\\f(-5) = -|(-5) - 5| - 4\\f(-5) = -|-10| - 4\\f(-5) = -10 - 4\\f(-5) = -14\\f(-5) = y = -14\\\\[/tex]
so:
x = -5
y = -14
( -5, -14)

HELP! Please!! Juan borrowed 12,00 from his friend eduardo and made an agreement to play him back over 2 years at an annual simple interest of 4% what is the total amount he will pay his friend back over the 2 years
Answer:
$12,960.00
Step-by-step explanation:
Use the formula A = P (1+rt)
A = (12000)(1+(0.04x2))
A = $12,960.00
Answer:
if the initial amount is 1200 then the answer is 1296
if the initial amount is 12000 then the answer is 12960
the initial number was unclear with the placement of the comma

We are going to fence in a rectangular field that encloses 75 ft2. Determine the dimensions of the field that will require the least amount of fencing material to be used.
Answer:
For width W and length L, we have:
W = L = √(75ft^2) = 8.66ft
Step-by-step explanation:
For a rectangle of length L and width W, the area is:
A = L*W
and the perimeter is:
P = 2*L + 2*W
First, we know that the area of our rectangle is:
A = 75ft^2 = L*W
And we want to minimize the perimeter of our rectangle, then we need to minimize:
P = 2*L + 2*W
From the equation:
75ft^2 = L*W
We can isolate one of the variables, let's isolate L
L = (75ft^2)/W
We could replace this in the perimeter equation:
P(W) = 2*( (75ft^2)/W) + 2*W
P(W) = (150 ft^2)/W + 2*W
To find the minimum of the perimeter we need to look at the zero of the first derivative of P(W).
P'(W) = dP(W)/dW = -(150ft^2)/W^2 + 2
Now we need to find the value of W such that:
P'(W) = 0
0 = -(150ft^2)/W^2 + 2
(150 ft^2)/W^2 = 2
(150ft^2) = 2*W^2
(150ft^2)/2 = W^2
75 ft^2 = W^2
√(75ft^2) = W = 8.66ft
And remember that:
L = (75ft^2)/W
replacing with W = √(75ft^2)
L = (75ft^2)/√(75ft^2) = √(75ft^2)
Then:
W = L = √(75ft^2) = 8.66ft

A map has a scale of 2 in. = 16 mi. If you measured the distance between two cities to be 19 in. on the map, how many miles would it actually be?
Answer:
Step-by-step explanation:
2 in/16mi = 19 in/x mi
152 mi
Answer:
16 miles = x miles
(1/2) inch 2 3/4 inches
x = (11/4) * 16 = (11/4) * 2 * 16 = 88 miles
(1/2)
Step-by-step explanation:
As was the case in your previous question, this problem involves setting two ratios equal to each other. We call such an equation a proportion.
find the volume of the composite figure
39in³ is a required volume.
Solution given:
for upper one
length[l]=8in
breadth[b] =3in
height[h]=1in
now
volume [V1]=l×b×h=8×3×1=24in³
again for lower one:
length[l]=6-1=5in
breadth[b] =3in
height[h]=1in
volume [V2]=l×b×h=5×3×1=15in³
Again
total volume =V1+V2=24in³+15in³=39in³

Answer:
1. The right triangles pass the AA similarity congruence theorem.
2. s/q
Step-by-step explanation:
They are similar since they pass the AA( Angle-Angle) similarity theorem.
Similar triangles have corresponding proportional sides so side z corresponds with side s and side x corresponds with q so we would represent that as
s/q
