Answer:

96

Step-by-step explanation:

area of a triangle = h x b/2 which means ill do

8 x 8 = 64

then 64/2

32

8x8 (again) = 64

64+32 = 96

Answer:

96 in^2. Find the area of the square, then the area of the triangle. After that, add them together.

Step-by-step explanation:

First, let's find the area of the square:
A = lw
A = 8 x 8
A = 64

Now, let's find the area of the triangle.
A = 1/2lh
A = 1/2(8)(8)
A = 1/2(64)
A = 32

Now, all we have to do is add 64 and 32 to get the total area

64 + 32 = 96

Answer:

its the 3rd one i think but don't trust me cuz ion know

The correct regarding the angles of the triangles are,

⇒ m ∠Y < m ∠Z < m ∠X  

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Since, Given that;

m ≥ 6, we will substitute 6 in for m.

This makes;

XZ = m-3 = 6-3 = 3.

XY = m+8 = 6+8 = 14.  

YZ = 2(6)+3 = 12+3 = 15.

Hence, This makes the sides, in order from least to greatest as;

XZ < XY < YZ.

Thus, The angles associated with these are opposite their corresponding sides; XZ corresponds with Y; XY corresponds with Z; and YZ corresponds with X.  

This means correct regarding the angles of the triangles are,

⇒ m ∠Y < m ∠Z < m ∠X  

Thus, The correct regarding the angles of the triangles are,

⇒ m ∠Y < m ∠Z < m ∠X

Answer:

x = 10/3 , y = 25/3

Step-by-step explanation:

Let's solve your system by substitution.

5x−2y=0 ; 5x+10y=100

Step 1: Solve 5x−2y=0 for x:

5x−2y=0

5x−2y+2y=0+2y (Add 2y to both sides)

5x=2y

5x=2y

5x/5=2y/5 (Divide both sides by 5)

x=2y/5 (Simplify)

Step 2: Substitute 2y/5 for x in 5x+10y=100:

5x+10y=100

5 2/5y +10y=100

12y=100 (Simplify both sides of the equation)

12y/12=100/12 (Divide both sides by 12)

y=25/3

Step 3: Substitute 25/3 for y in x=2/5y

x=2/5y

x=2/5 * 25/3

x=10/3 (Simplify both sides of the equation)

At the end we have the following answers :

x = 10/3

y = 25/3

Answer: A

Step-by-step explanation: I has a negative slope, which means that its line is shaped like a backslash. This graph is shaped like a forward slash, so it cannot be that one. III is a quadratic equation in factored form. The graph for a quadratic equation is shaped like a U or an upside down U, so it cannot be that one either. Using process of elimination, the only one that it can be is A, II and III.

Answer:

Step-by-step explanation:

The a line that is perpendicular to the reference line will have a slope that is the negative inverse of the slope of the reference line.  We'll look for a line that has the form y=mx+b, where m is the slope and b is the y-intercept. The reference line y=(4/3)x has a slope of (4/3) and a y-intercept of 0 (it crosses the y axis at x = 0).  

The negative inverse the the slope (4/3) would be -(3/4).

The new line will be y = -(3/4)x + b.  

To find point, use the given point and solve for b:

y = -(3/4)x + b

y = -(3/4)x + b   for point (4,2)

2= -(3/4)(4) + b

2= -3 + b

b = 5

The equation of the perpendicualr line is y = -(3/4)x + 5

Step-by-step explanation:

The probability of selecting exactly one ace is its likelihood

The probability that a five-card poker hand contains exactly one ace is 29.95%

There are 4 aces in a standard deck of 52 cards.

The probability of selecting an ace would be:

p = 4/52

Also, there are 48 non-ace cards in the standard deck

So, the probability of selecting a non-ace after an ace has been selected is:

p = 48/51

The probability of selecting a non-ace up to the fifth selection are:

The required probability is then calculated as:

P(1 Ace) = n * (4/52) * (48/51) * (47/50) * (46/49) * (45/48)

Where n is the number of cards i.e. 5

So, we have:

P(1 Ace) = 5 * (4/52) * (48/51) * (47/50) * (46/49) * (45/48)

Evaluate

P(1 Ace) = 0.2995

Express as percentage

P(1 Ace) = 29.95%

Hence, the probability that a five-card poker hand contains exactly one ace is 29.95%

Answer:

y=f(x+9)-5

Step-by-step explanation:

to move the graph 9 units to the left, you would need to add 9 to the variable (which is x) - so that transformation for y=f(x) would look like this:

y=f(x+9)

then, to move the graph 5 units down, you would need to subtract 5 from f(x), so the transformation for y=f(x) that moves the graph 5 units down would be:  

y=f(x)-5

now, you would put that all together and it would look like this:

y = f (x+9) -5

i hope this helps.

Answer:

Step-by-step explanation:

The y values differ by 1. They are also 1 larger than the x value.

The equation is y = x + 1

Use x = 4 ans an  example

y = x +  1

x = 4

y = 4 + 1

y = 5

At least for this example the equation works. It will for all the others as well.

The sequence an = -5 + (n - 1)14 is an arithmetic sequence

The value of a10 is 121

The sequence is given as:

an = -5 + (n - 1)14

To calculate the value of a10, we set n = 10

So, we have:

a10 = -5 + (10 - 1) * 14

Evaluate the difference

a10 = -5 + 9 * 14

Evaluate the product

a10 = -5 + 126

Evaluate the sum

a10 = 121

Hence, the value of a10 is 121

then 8•12 for the square in the middle

By finding the circumference of the plate, we conclude that the ribbon must be  43.96 in long.

Remember that for a circle of radius R, the circumference is:

C = 2*pi*R

In this case, the ribbon must be equally long to the circumference of the plate. We know that the diameter of the plate is 14 inches, and the radius is half of that, then we get:

R = 14in/2 = 7in

Replacing that on the circumference equation we get:

C = 2*3.14*7in = 43.96 in

The ribbon must be 43.96 in long.
