Please help! In the figure below, what is the length of EG
Answer:
Step-by-step explanation:
The triangles are similar because they have two sides and the angle between them (EFG) respectively equals, and it’s evident the factor between the two triangles is 2. So EG=2CB=2*8=16
Answer:
the value of EG is 20.
Step-by-step explanation:
3×4 = 12, AB and EF is similar but the value of AB is multiplied by 4 to become 12 for EF.
similarly, 4×4 = 16, BC and FG is similar but the value of BC is multiplied by 4 to become 16 for FG..
In this way, AC and EG are also similar so 5×4 = 20.
All the values are multiplied by 4 ...
2i-3n=8
i+2n=-3
find i and n
Answer: n = -2; i = 1
Step-by-step explanation:
i + 2n = -3
i = -3 - 2n
Plug in i in 2i - 3n = 8, we get:
2i - 3n = 8
2(-3 - 2n) - 3n = 8
-6 - 4n - 3n = 8
-6 - 7n = 8
-7n = 14
n = -2
substitute n = -2 into i = -3 - 2n
i = -3 - 2n
i = -3 - 2(-2)
i = -3 + 4
i = 1

ABC and ADE are similar. Find the length of size CA
Answer:
since ABC and ADE are similar,they have equal areas.
(AC)^2/(AE)^2=area ABC/ADE
areaABC=ACE=1
so substitute it in the afformentioned equation
u will get,AC=AE
The length of side CA in triangle ABC is c * (a² + ab + ac) / (a * (a + b + c)).
To find the length of side CA in triangle ABC, we need to use the concept of similarity and corresponding sides. Let's denote the lengths of sides in each triangle:
Triangle ABC:
Length of side AB: a
Length of side BC: b
Length of side CA: c
Triangle ADE:
Length of side AD: x (corresponding to side AB in ABC)
Length of side DE: y (corresponding to side BC in ABC)
Length of side EA: z (corresponding to side CA in ABC)
Since triangles ABC and ADE are similar, their corresponding sides are in proportion:
AD/AB = DE/BC = EA/CA
We know that AD corresponds to AB, and DE corresponds to BC, so we can set up the following proportions:
x/a = y/b
Solving for y, we get:
y = (b * x) / a
Next, we can set up the proportion for EA/CA:
z/c = x/a
Solving for z, we get:
z = (c * x) / a
Now, we have expressions for y and z in terms of x, a, and b. Since the sum of the lengths of the sides of a triangle is always constant, we can write the equation:
x + y + z = a + b + c
Substituting the expressions for y and z:
x + (b * x) / a + (c * x) / a = a + b + c
To find the value of x, we can multiply the entire equation by a to eliminate the denominator:
a * x + b * x + c * x = a² + ab + ac
Combining the x terms:
x * (a + b + c) = a² + ab + ac
Dividing both sides by (a + b + c):
x = (a² + ab + ac) / (a + b + c)
Now that we have found the value of x, we can substitute it back into the expression for z:
z = (c * x) / a
z = (c * (a² + ab + ac) / (a + b + c)) / a
Simplifying:
z = c * (a² + ab + ac) / (a * (a + b + c))
Thus, we have found the length of side CA in triangle ABC:

Find the area of the triangle below.
Carry your intermediate computations to at least four decimal places. Round your answer to the nearest tenth.
The area of the triangle is the amount of space on it.
The area of the triangle is 85.5 square yard
How to determine the area of the triangle?The given parameters are:
a = 12 yd
b = 16 yd
c = 15 yd
Start by calculating the semi-perimeter (s)
s = 0.5 * (a + b + c)
This gives
s = 0.5 * (12 + 16 + 15)
s = 21.5
The area of the triangle is then calculated as:
[tex]A = \sqrt{s * (s - a) * (s - b) * (s - c)[/tex]
This gives
[tex]A = \sqrt{21.5 * (21.5 - 12) * (21.5 - 16) * (21.5 - 15)[/tex]
Evaluate the product
[tex]A = \sqrt{7301.9375[/tex]
Evaluate the square root
A = 85.5
Hence, the area of the triangle is 85.5 square yard

The simplified fraction representing the ratio 0.45 to 1.35 is 1/3.
To express the ratio 0.45 to 1.35 as a simplified fraction, we can divide both numbers by their greatest common divisor (GCD) to simplify the ratio. In this case, the GCD of 45 and 135 is 45.
So, divide both numbers by 45:
0.45 ÷ 45 = 0.01
1.35 ÷ 45 = 0.03
The simplified ratio is 0.01 to 0.03. To make it an integer ratio, we can multiply both parts by 100:
0.01 * 100 = 1
0.03 * 100 = 3

An investment of $42 earns 12.5% simple interest for 4 years. How much is to worth?
O $85.50
O $77.76
O $63
O $9.83
Total amount after 4 years will be $63. If he invest principle amount of $42 for rate of interest of 12.5%.
How to calculate total amount ?Simply multiply the principal amount by the interest rate and the time to calculate simple interest. "Simple Interest = Principal x Interest Rate x Time," the formula says. You must multiply the borrowed principal amount by 1 plus the interest rate.
The simple interest rate is the rate at which you borrow or lend money. When a borrower borrows money from a lender, the lender receives an additional sum of money. The principal is the borrowed money that is given for a specific period of time. The interest is the extra amount paid back to the lender for using the money.
First, converting R percent to r a decimal
r = R/100 = 12.5%/100 = 0.125 per year.
To find the total amount A = P (1+rt).
= 42(1 + 0.125 *6)
= $63
The total amount is $63
