Find the area of trapezoids
Answers
Answer:
Area is 10.5
Step-by-step explanation:
We can use the trapezoid formula of
[tex]A = \frac{a+b}{2}h[/tex]
A = (2 + 5) / 2 * 3 = 3.5 * 3 = 10.5
or break it into a rectangle and a triangle (natural split by y axis).
A = 2 * 3 + 3 * 3 / 2 = 6 + 9 / 2 = 6 + 4.5 = 10.5
Answer:
10.5 units²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = OS = 3 , b₁ = OC = 5 , b₂ = SK = 2 , then
A = [tex]\frac{1}{2}[/tex] × 3 × (5 + 2) = 1.5 × 7 = 10.5 units²

Since multiplication is implied algebra we often don't need to actually write the times symbol ‘×'. Re-write this algebraic equation without the times symbol. a × b = 4 × c
Answers
Answer:
ab=4c
Step-by-step explanation:
Since a and b are being multiplied, we can just right ab. Since 4 and c are being multiplied, we ca just right 4c.
Answer:
ab=4c
Step-by-step explanation:
Basically, if you see any variables that are together like that or numbers side by side with letters, it means it's just being multiplied! This doesn't however, work with numbers next to numbers. So for example:
Say you have a x b = 5 x 5c
It would be ab = 5 x 5c Because only letters get put next to each other. That's really the only way I know how to explain it. Have a great day and good luck!

There were 680 gallons of water ALREADY in a 1600-gallon pool. Water is being pumped into the pool at the rate of 320 gallons per hour. Let x represents the number of hours. Find how many hours it will take to fill the pool.
Answers
Answer:
2 7/8 hours
Step-by-step explanation:
Answer:
2hrs 12 mins
Step-by-step explanation:
5hrs = 5x = 1600 question asks us to find 680
2 1/2x + 680-640 =-x + 2.8hrs
2x + 40 = x + 2.8hrs
2x + 40 = 680
Then use the 2.8 to convert into hrs : minutes ie) 0.8 x 60
0.8 * 60 = 48 minutes
Then go back to x + 2.8hrs = x + 2hrs 48mins
2x + 48 = 60
2x + 48 = 60
2x+ 60 - 48
x = 2:12 hours

Which of the following points lies on the graph of y=x^2-5?
Answers
Answer:
(-2,-1)
Step-by-step explanation:
The point (-2, -1) lies on the graph of y=x²-5
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given function is y=x²-5
A relation is a function if it has only one y-value for each x-value.
We have to find the points which lies on the graph of y=x²-5
The graph is a parabola which has vertex of (0, -5)
Let us find few points of function
When x=-2, y=-1
When x=0, y=-5
when x=1, y=-4
when x=2, y=-1
when x=3, y=4
when x=4, y=11
when x=5, y=20
Hence, the point (-2, -1) lies on the graph of y=x²-5

Write this word sentence as an equation. 82 is the difference of a number b and 24
Answers
Answer:
106 - 24 = 82
Step-by-step explanation:
b = 106, solve 106 - 24 and you get 82.
Hope this helped.
Answer:
b/24=82
Step-by-step explanation:
Since the difference of an equation is the outcome of division we place 82 as the answer.
Also, since 82 is greater than 24 we can assume that the variable "b" is larger than both 82 and 24.

Write an expression, in its simplest form, for the volume of this cuboid
Answers
Answer:
[tex]V=10x^2+35x+15[/tex]
Step-by-step explanation:
Given that,
Length = (2x+1)
Width = (x+3)
Height = 5
We need to find an expression for the volume of this cuboid . The formula for the volume of cuboid is given by :
[tex]V=lbh[/tex]
So,
[tex]V=(2x+1)\times (x+3)\times 5\\\\=(2x+1)\times (5x+15)\\\\=10x^2+30x+5x+15\\\\=10x^2+35x+15[/tex]
So, the volume of this cuboid is equal to [tex]10x^2+35x+15[/tex].

What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, The speed of a truck, s, must be no less than 34 miles per hour.
Therefore, The speed of the truck must be greater than or equal to 34 miles per hour.
So, The inequality that represents this context is,
s ≥ 34.
