what is the formula for area of a triangle
Answer:
A = [tex]\frac{1}{2}[/tex]bh
Step-by-step explanation:
The area of a triangle is defined as half the product of its base by its height.
A = [tex]\frac{1}{2}[/tex]bh
If you do not know the height but you know the length of the three sides of the triangle you can use Heron's formula to find the area
If the lengths of the sides are a, b, c then the area is
[tex]A = \sqrt{s(s-a)(s-b)(s-c)}[/tex]
Where
[tex]s =\frac{a+b+c}{2}[/tex]
You do length x width (for triangles its called base x height) and divide the product by 2
The product of two whole numbers is 180 and their sum is36. What are the two numbers?
Answer:
6,30
Step-by-step explanation:
The product of two whole numbers is 180
xy = 180
and their sum is 36
x+y = 36
x = 36-y
Substitute this into the first equation
(36-y) (y) = 180
36y - y^2 = 180
Add y^2 to each side
36y = 180 +y^2
Subtract 36y from each side
0 = y^2 -36y +180
Factor
0=(y-6) (y-30)
Using the zero product property
y-6 =0 y-30 =0
y = 6 y= 30
Now we need to find x
If y =6
x = 36-6=30
If y = 30
x = 36-30=6
The two numbers are 30 and 6

What is the volume of the cylinder below
Answer: D)
Step-by-step explanation: this is because you find the area of the circle which is pi times radius squares. So the area of the circle is 16 pi. And the. You have to multiply by 7 because you are staking the circle 7 times. To get 122 pi which is the answer so the answer is D. :)
The value of the volume of the cylinder is,
V = 96π units³
What is cylinder?A cylinder is a three-dimensional solid that maintains, at a given distance, two parallel bases connected by a curved surface. These bases often have a circular form (like a circle), and a line segment known as the axis connects the centres of the two bases.
We have to given that;
Radius of cylinder = 4 units
Height of cylinder = 6 units
Since, The value of volume of cylinder is,
⇒ V = πr²h
Hence. The value of the volume of the cylinder is,
V = π (4²) × 6
V = 16 × 6 π
V = 96π units³
Thus, The value of the volume of the cylinder is,
V = 96π units³

A bicyclist covered 5/7 of his route and an additional 40 miles. He has yet to cover 118 miles less than 0.75 of his route. How long is his route in miles?
Answer:
168 miles.
Step-by-step explanation:
5/7x+40+0.75x−118=x
Step 1: Simplify both sides of the equation.
5/7x+40+0.75x−118=x
5/7x+40+0.75x+−118=x
(5/7x+0.75x)+(40+−118)=x(Combine Like Terms)
1.464286x+−78=x
1.464286x−78=x
Step 2: Subtract x from both sides.
1.464286x−78−x=x−x
0.464286x−78=0
Step 3: Add 78 to both sides.
0.464286x−78+78=0+78
0.464286x=78
Step 4: Divide both sides by 0.464286.
0.464286x/0.464286=78/0.464286
x=168
The total length of the bicyclist's route is 560 miles. This is solved by setting up an equation based on the given information and solving for the total route length.
Explanation:To solve this problem, we first need to represent the problem using equations by setting X as the total route. We know that the bicyclist has already covered 5/7 of his route and an additional 40 miles. So, the part of his route he has already covered is expressed as [tex](5/7)X + 40.[/tex]
We also know that he has yet to cover 118 miles less than 0.75 of his route, so the part of the route that he has yet to cover is expressed as 0.75X - 118. Since the parts of the route already covered and yet to be covered add up to be his entire route (X), we can set up the equation as follows: ([tex](5/7)X + 40 = 0.75X - 118[/tex]. By solving this equation, we find that X (the total length of his route) equals 560 miles.

There are 25 students in Mrs. Venetozzi’s class at the beginning of the school year, and the average number of siblings for each student is 3. A new student with 8 siblings joins the class in November.
Adding the student with eight siblings will increase the class average amount of siblings because this student has more siblings than the average.
The new class average for number of siblings is 3.19
Therefore, the average number of siblings that each student has is larger than the original average.
Answer:
The average will go up.

A preschool playground has both bicycles and tricycles. There is a total of 30 seats and 70 wheels. how many bicycles are there? how many tricycles are there?
Answer:
20 bicycles and 10 tricycles.
Step-by-step explanation:
Let the number of bicycles and tricycles be x and y respectively.
Each vehicle has 1 seat. Each bicycle 2 wheels and each tricycle 3 wheels.
Then we have the system of equations:
x + y = 30 ............ (1)
2x + 3y = 70.........(2)
Multiply the first equation by -2:
-2x - 2y = -60......(3)
Adding (2) + (3):
y = 10
Substituting for y in equation (1):
x + 10 = 30
x = 20.
By simultaneous equation, there are a total of 20 bicycles and 10 tricycles.

Answer:
A. 19
Step-by-step explanation:
2(4z -9 -7) = 166 -46
First combine like terms
2(4z -16) = 120
Divide each side by 2
2/2(4z -16) = 120/2
4z-16=60
Add 16 to each side

Find the measure of a central angle of a regular polygon with 10 sides
Answer:
114 degrees
Step-by-step explanation:
The formula to find the measure of all angles in a regular polygon is [tex](n-2)180[/tex], where n = total number of sides.
Thus, we substitute n for 10, and you get:
[tex](10-2)180=1440[/tex]
If the shape is a regular polygon and it has ten sides, meaning all sides are equal, then all you do is divide 1440 by 10, to get the final answer of 114.
A central angle in a regular ten-sided polygon would be 144 degrees.
Final answer:
The central angle of a regular polygon with 10 sides (a decagon) is calculated by dividing 360° by the number of sides, resulting in a central angle of 36°.
Explanation:
To find the measure of a central angle of a regular polygon with 10 sides (a decagon), we use the formula for the measure of each central angle:
Central Angle = 360° / Number of sides
Thus, the central angle of a regular decagon is:
360° / 10 = 36°
This is because the central angles are equally distributed around the center point, dividing the 360° of a circle evenly by the number of sides in the polygon.
What value makes this equation true? 4x-3=0?
Answer:
x = 3/4
Step-by-step explanation:
4x-3=0
Add 3 to each side
4x-3+3 = 0+3
4x = 3
Divide each side by 4
4x/4 = 3/4
x = 3/4
Answer: X = 3/4
Solution:
Move the constant to the right side and change its sign, then divide both sides by four:
4x - 3 = 0 --> 4x = 3 --> (4x/4) = (3/4)
X = 3/4
