The formula for finding the area of a triangle is:
[tex]\frac{1}{2} bh[/tex]
The "b," is the base (7), and the "h," is the height (8):
[tex]\frac{1}{2} (7)(8)[/tex]
[tex]\frac{1}{2} (56)[/tex]
28
"The area of triangle [tex]IHC is $\boxed{\frac{1}{2} \times b \times h}$[/tex], where [tex]$b$[/tex] is the base of the triangle and[tex]$h$[/tex]is the height of the triangle.
To determine the area of triangle IHC, we need to know the lengths of the base and the height. The area of a triangle is given by the formula:
[tex]\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \][/tex]
In the case of triangle IHC, if we let b represent the length of the base IH, and h represent the length of the height from point H to side IH, then the area of triangle IHC can be calculated using these values.
Without specific numerical values for b and h, we cannot calculate a numerical area. However, if the values of b and h are provided, we can substitute them into the formula to find the area. For example, if b = 6 units and h = 4 units, then the area would be:
[tex]\[ \text{Area} = \frac{1}{2} \times 6 \times 4 = \frac{1}{2} \times 24 = 12 \][/tex]
Thus, the area of triangle IHC with a base of 6 units and a height of 4 units would be 12 square units. If the actual lengths of the base and height are different, those values should be substituted into the formula to calculate the correct area."

What is the length of BC¯¯¯¯¯¯¯¯?
Enter the correct value.
Answers
Answer:
Triangle ACB = Triangle ADB
=> BC = BD
=> -2x+85 = 5x - 48
=> x = 133/7 = 19
=> BC = -2 x 19 + 85 = 47
If we are provided with the value of AC or CD, we can calculate the length of BC is 47
Let's first determine the lengths of segment BC and BD in terms of x using the given expressions:
BC (B C¯¯¯¯¯¯¯¯) = -2x + 85
BD (B D¯¯¯¯¯¯¯¯) = 5x - 48
Now, as ACB and ADB are right angles, we can utilize the property of perpendicular chords intersecting a circle to find the value of x. When two chords intersect inside a circle, the product of their segments is equal. Therefore, we can set up the following equation:
BC * BD = (AC * CD) [Property of perpendicular chords intersecting]
Substitute the values:
=> BC = BD
When we simplify this one, then we get,
-2x+85 = 5x - 48
Then the value of x is calculated as,
x = 133/7 = 19
BC = -2 (19) + 85 = 47

Suppose that the amount of algae in a pond doubles every 3 hours. If the pond initially contains 50 pounds of algae, how much algae will be in the pond after 8 hours.In this exponential situation, what would the y-intercept be? CHOICES:
(0,3)
(0,2)
(0,50)
(0,8)
Answers
Answer:
After 8 hour there will be 317.64 pounds of algae.
y-intercept: (0, 50)
Step-by-step explanation:
At time = 0 hours, there are 50 pounds of algae, after 3 hour there will be 100 pounds of algae, after 6 hour there will be 200 pounds of algae, and so on.
Exponential growth is modeled by the following equation:
y = x0*(1 + r)^t
where x0 is the amount of algae at the beginning, r is the rate of change, and y is the amount of algae after t hours. Replacing with data:
100 = 50*(1 + r)^3
2 = (1 + r)^3
ln(2) = 3*ln(1 + r)
r = exp(ln(2)/3) - 1
r = 0.26
This result can be checked as follows
y = 50*(1 + 0.26)^6 = 200
After 8 hours:
y = 50*(1 + 0.26)^8 = 317.64
The y-intercept corresponds to t = 0
y = 50*(1 + 0.26)^0 = 50

You can substitute the value "-3" for x and "-1" for y in each of the equations given. Whichever equation is correct when simplified is the line that the point (-3, -1) lies on:
[tex]-1 = -4(-3)-6\\\\-1=3(-3)+9\\\\-1=-3(-3)-10\\\\-1=5(-3)-1[/tex]
Simplifying the right side of each equation:

Second equation: -1 = 0
Third equation: -1 = -1
Fourth equation: -1 = -16

The price of cotton candy at the park is $6.00.
The markup rate of 300% means the price is increased by three times the cost. So, $1.50 * 3 = $4.50 is the markup cost. Adding the original cost to the markup cost gives $1.50 + $4.50 = $6.00.

the perimeter of an equilateral triangle is 150cm. If the length of the altitude of the triangle is x√3cm, what is the value of x?
Answers
Answer:
X = 25
Step-by-step explanation:
To solve this question, we'll first of all find determine the side length of the triangle from the perimeter.
Perimeter of an equilaterial triangle = 3 * s
S = side length
Perimeter = 150cm
150 = 3s
S = 150 / 3
S = 50cm
The side lengths are 50cm each since they are all equal.
To find x,
We have to divide the triangle equally into two different part.
Check the first attachment for better illustration on how the equilaterial triangle is.
Check the second attachment for better illustration on the triangle when its divided into a right angle triangle.
From the right angle triangle, we can use pythagorean theorem to solve for x
a² = b² + c²
a = 50cm
b = 25cm
c = x√(3)
50² = [x√(3)]² + 25²
2500 = x² * 3 + 625
2500 - 625 = 3x²
1875 = 3x²
X² = 1875 / 3
X² = 625
X = √(625)
X = 25

Answers
The Pythagorean theorem can only be applied to right triangles.
Explanation:The Pythagorean theorem can be applied to right triangles only.
It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
So, while the Pythagorean theorem cannot be applied to every triangle, it can be used to find the length of one side of a right triangle given the lengths of the other two sides.

The first term of the series is 81
Step-by-step explanation:
The sum of the nth term of a geometric sequence is expressed as shown;
Sn = a(1-rⁿ)/1-r for r<1
a is the first term
r is the common ratio
n is the number of terms
Given Sn = 171
r = 2/3
n = 3
a =?
Substituting the values in the equation
171 = a(1-(2/3)³)/1-2/3
171 = a(1-8/27)/(1/3)
171 = a(19/27)/(1/3)
171 = a × 19/27 × 3/1
171 = a × 19/9

10 is your answer for c.
Step-by-step explanation:
Isolate the variable c. Note the equal sign, what you do to one side, you do to the other.
Subtract 3c from both sides:
3c (-3c) - 10 = 2c (-3c)
-10 = 2c - 3c
-10 = -c
Isolate the variable, c. Divide -1 from both sides:
(-c)/-1 = (-10)/-1
c = -10/-1
c = 10
c = 10 is your answer.

Step-by-step explanation:
Final answer:
The correct expression for the total square footage that Mandy painted is 4 × 10 squared, which totals 400 square feet when calculated.
Explanation:
The expression that represents the total square footage that Mandy painted when she paints four square walls that are ten feet on each side is 4 × 10 squared. To understand why, let us analyze a related problem where Marta has one square with a side length of 4 inches and another larger square with dimensions that are twice the first square, which means the side length of the larger square is 8 inches (4 inches × 2).
The area of a square is calculated by squaring its side length, so the smaller square has an area of 16 square inches (4 inches squared), and the larger square will have an area of 64 square inches (8 inches squared). This demonstrates that the area of the larger square is four times larger than the area of the smaller square, as the scale factor of the side lengths is squared to obtain the ratio of the areas.
Similarly, for Mandy's wall painting, each wall is 10 feet by 10 feet, so the area of one wall is 10 feet squared, which equals 100 square feet. Since there are four walls, the total area is 4 × 100 square feet, or 400 square feet in total. The correct expression for the total square footage Mandy painted is 4 × 10 squared.
