Blank - 3/10 = 1/5 What is the blank number
Answer:
1/2
Step-by-step explanation:
Let's consider the number we want is x
x-3/10=1/5
On both sides of the equation, if we substract (or add) a certain number, say 3/10, the equality relation still exists.
That is x-3/10+3/10=1/5+3/10
Then x=1/5+3/10
You see 1/5+3/10=2/10+3/10=1/2
So x=1/2
Mr. Morris is going to save money and replace his sailboat's mainsail himself. He must determine the area of the mainsail in order to buy the correct amount of material. Calculate the area of the parallelogram to determine how much material should be purchased. Be sure to explain how to decompose this shape into rectangles and triangles. Describe their dimensions and show your work.
Answer:
The area of the parallelogram is equal to 300 square feet.
Step-by-step explanation:
Select the graph of the solution set that would represent the following expression. 2 ( x + 1 ) > 3 x − 2
Hey there!
2(x + 1) > 3x - 2
DISTRIBUTE 2 WITHIN the PARENTHESES:
2(x) + 2(1) > 3x - 2
CONVERSION:
2x + 2 > 3x - 2
SUBTRACT 2 to BOTH SIDES:
-x + 2 - 2 > -2 - 2
SIMPLIFY IT!
NEW EQUATION:
-x > -4
CONVERSION 2:
-1x > -4
DIVIDE -1 to BOTH SIDES
-1x/-1 > -4/-1
SIMPLIFY IT!
x < 4
Therefore, your answer is: x < 4
Good luck on your assignment & enjoy your day!

We are given with an inequality and need to find it's solution set and need to represent it on number line too. Let's start !!!!
[tex]{:\implies \quad \sf 2(x+1)\> 3x-2}[/tex]
[tex]{:\implies \quad \sf 2x+2\> 3x-2}[/tex]
Subtracting 2x from both sides ;
[tex]{:\implies \quad \sf \cancel{2x}+2-\cancel{2x}\> 3x-2-2x}[/tex]
[tex]{:\implies \quad \sf 2\> x-2}[/tex]
Adding 2 to both sides :
[tex]{:\implies \quad \sf 2+2\> x-\cancel{2}+\cancel{2}}[/tex]
[tex]{:\implies \quad \sf 4\> x }[/tex]
[tex]{:\implies \quad \sf x\< 4}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{x\in (-\infty,4)}}}[/tex]

What is the volume of the
rectangular prism?
Answer:
We are already given the length of the prism, so now we need to find the height and width.
4 units across is the width, and 2 units up is the height
In order to find the volume of a rectangular prism we must multiply the length, width, and height.
In this case, 4 is our width, 2 is our height, and 7 is obviously our length.
Now let's multiply;
4 x 2 x 7 = 56 cubic centimeters
to make this easier to multiply we could also do
(4 x 2) x 7 or 4 x (2 x 7)

In the graph we can identify two local minimums, with values y = 0, and at the x-values:
x = -3 and x = 3.
What is a local minimum?For a function f(x), we define a local minimum on an interval (a, b) if for a value c ∈ (a, b), then:
f(c) ≤ f(x) ∀ x ∈ (a, b)
a) On the image we can see two local minimums (the two lowest points on the graph). The values of the minimums are both 0.
b) The values of x where we have the minimums are:
x = -3 and x = 3.

A circular table has a radius 56cm. A tablecloth covers the table. The edge of the cloth is 10cm below the tabletop. What is the area of the tablecloth?
Answer:
13,363.84 square cm
Step-by-step explanation:
For this question,
The circle table has a radius of 56 cm and the height of the edge of the cloth is 10cm(height) below the tabletop, which is a rectangle
We need to find out the area of a circle, Then the area of the rectangle.
Area of circle FORMULA= πr^2 | Area of rectangle FORMULA = l * h
πr^2
3.14 * 56 * 56 = area of circle = 9,847.04
[(2*3.14*56)Perimeter of circle which is also length of rectangle] * 10 = area of rectangle = 3516.8
9,847.04 + 3516.8 = 13,363.84

he slope of the line that contains the points (1, -1) and (2, 3) is 4. What is the y-intercept? A. 5 B. 4 C. -4 D. -5
Answer:
D
Step-by-step explanation:
Equation of a line given by the two-point form is:
(y-y1)/(x-x1) = (y1-y2)/(x1-x2)
(y-(-1))/(x-1) = (-1-3) / (1-2)
(y+1)/(x-1) = -4 / -1
y+1 = 4(x-1)
y = 4x-4-1
y = 4x - 5
y-intercept at x=0 is -5
Answer is D.
Solution:
We know that:
Given points: (1, -1) and (2, 3)Slope = 4Picking any point:
=> (1, -1)Using point slope form:
y - y₁ = m(x - x₁)y - (-1) = 4(x - 1)y + 1 = 4x - 4y = 4x - 4 - 1y = 4x - 5Comparing the equation with the formula:
y = (m)x + (b) and y = (4)x + (-5)⇒ m = slope = 4
⇒ b = y-intercept = -5

Ashley painted 1/2 of her bathroom ceiling. Alex painted 1/4 of the ceiling in the school library. Who painted the larger fraction of their ceiling? Use a picture to demonstrate you answer.
Answer:
Ashley painted the larger fraction of their ceiling.
Step-by-step explanation:
I have no idea how large this ceiling is in this problem or what rate they are painting at; However, 1/2 is considered larger than 1/4.
Answer:
Ashley: 1/2 = 0.5
Alex: 1/4 = 0.25
0.25 < 0.5 Therefore Ashley painted more of their ceiling.
