Faith makes greeting cards with colored paper. She plans to make 15 of the cards out of red paper. She has 25 sheets of colored paper in all. If she uses all the colored paper she has, how many sheets are a color other than red?
Answer:
5
Step-by-step explanation:
because..............
Using fraction, the sheets are a color other than red is 5.
What is fraction?Fraction is a "number are expressed as quotient, where numerator is divided by denominator".
According to the question,
Faith has 25 sheets of colored paper. She plans to make 15 of the cards out red paper.
[tex]\frac{15}{25}[/tex] = [tex]\frac{3}{5}[/tex]
5 - 3 =2
Fraction 5 parts of sheets is equal to 25, 3 parts of sheet is equal to 15.
5 = 25
2 = x
5 × 5 = 25
2 × 5 = 10
Hence, using fraction the number of sheets are a color other than red is 5.

On a coordinate plane, a circle has a center at (0, 0). Point (0, negative 5) lies on the circle. The point (0, 5) lies on a circle that is centered at the origin. Does (–3, –4) also lie on the circle? Identify the radius from the graph. r = __units Determine the distance from the center to (–3, –4) using the distance formula. distance =___ units Compare the radius to the distance. Does the point (–3, –4) also lie on the circle?
The point (–3, –4) does lie on the circle with a center at (0, 0).
We know that the point (0, 5) lies on the circle, and since the center is at (0, 0), the distance from the center to (0, 5) gives us the radius.
Using the distance formula:
radius = √((0 - 0)² + (5 - 0)²)
= √0+25
=√25
= 5 units
So, the radius of the circle is 5 units.
Next, let's determine the distance from the center (0, 0) to the point (–3, –4) using the distance formula:
distance = √ (0- (-3))²+ (0-4(-4))²
= √ 3² + 4²
= √9 +16
= √25
= 5 units
The distance from the center to (–3, –4) is also 5 units.
Since the distance from the center to (–3, –4) is equal to the radius of the circle, the point (–3, –4) lies on the circle.
Therefore, the point (–3, –4) does lie on the circle with a center at (0, 0).

Marvin is painting three squares shaped like the one below if it takes him exactly 4 cans of paint to paint square 3 five cans of paint to paint square to how many cans of paint should he need to paint square one
Complete question:
Marvin is painting three squares shaped like the one below if it takes him exactly 4 cans of paint to paint square 3, five cans of paint to paint square 2 to how many cans of paint should he need to paint square one
Picture of squares is attached.
Answer:
9 cans of paint.
To paint square 1, he needs 9 cans of paint.
Step-by-step explanation:
Given that to paint square 3, four cans of paint are needed.
Therefore, let's take area of the square 3 as 4.
i.e a² = 4
Solving further, we have :
[tex] a = \sqrt{4} [/tex]
a = 2
We can say, each side of square 3 = 2 units
To paint square 2, five cans of paint are needed. Let's take the area of 2 to be 5.
i.e b² = 5
Solving further, we have :
[tex] b = \sqrt{5} [/tex]
We can say, each side of square 2 = [tex] \sqrt{5} [/tex] units
Using Pythagoras theorem, we have that the area of the square of a hypotenuse in a 90° angle is equal to the sum of the areas of the other two squares.
Therefore,
[tex] h^2 = 2^2 + \sqrt{5}^2 [/tex]
h² = 4 + 5
[tex] h = \sqrt{9} [/tex]
h = 3 units.
We now know one side of the square 1 is 3 units.
Area of square 1 = 3²
Area = 9.
Therefore to paint square 1, he needs 9 cans of paint.

The side on a clip board appears to be a right triangle. The leg lengths are 2 millimeters and 2.1 millimeters and the hypotenuse is 2.9 millimeters. Is the side of the clip a right triangle?
Answer:
Yes, it is a right angle triangle
Step-by-step explanation:
Let leg lengths be y and z
Y = 2mm
Z = 2.1mm
Let x represent hypothenus
X = 2.9mm
To find out if it's a right angle triangle, we'll use pythagorean theorem since it's true for all right angle triangles I.e the square of the hypothenus is equal to the square of both sides(opposite and adjacent)
x² = y² + z²
x² = 2² + 2.1²
x² = 4 + 4.41
x² = 8.41
Take the square root of both sides
x = √(8.41)
x = 2.9mm
Therefore since the square of two other sides equal the square of the hypothenus, the side of the clip is a right angle triangle

A system of equations is a collection of related equations
The system of equations that can be used to solve [tex]12x^3 - 5x = 2x ^2 + x + 6[/tex] [tex]y = 2x ^2 + x + 6[/tex] and [tex]y= 12x^3 - 5x[/tex]
The equation is given as:
[tex]12x^3 - 5x = 2x ^2 + x + 6[/tex]
Split the above equation into 2, and set both equations to 0
[tex]12x^3 - 5x = 0[/tex]
[tex]2x ^2 + x + 6 = 0[/tex]
Replace the "0" with y, in both equations
[tex]12x^3 - 5x = y[/tex]
[tex]2x ^2 + x + 6 = y[/tex]
Rewrite the equations as:
[tex]y = 2x ^2 + x + 6[/tex]
[tex]y= 12x^3 - 5x[/tex]
Hence, [tex]y = 2x ^2 + x + 6[/tex] and [tex]y= 12x^3 - 5x[/tex] can be used to solve [tex]12x^3 - 5x = 2x ^2 + x + 6[/tex]

Answer:
5*14=70
Step-by-step explanation:
Divide 28 by 2 because it is the second on the number line and because Jonah folded 2 shirts in that time. You would get 14. You then get a speed of 1 shirt every 14 seconds. That means if you multiply 5 with 14, you'd get the number of seconds it'd take for Jonah to fold her clothes. Not a nice chore I must say. Pardon my english, and hope this helps :)

*Hint: Subtract the percentage from 100 and write it as a decimal*
Answer:
P=100-0.18
Step-by-step explanation:
Remember, percent means per every 100. So if the car cost $100, Mr. Stanley saves $18 on the car. Also, 18%= 0.18. And just for extra, single digit percents would be expressed with an extra zero in front of it, such as 5%=0.05.
Kiyo is designing a rectangular garden with a 2-ft wide path all the way around it. The length of the garden is 3 times as long as the width. Kiyo models the area of his garden and the path with the equation f(x) = (x + 2)(3x + 2). Explain Kiyo’s error
Answer:
The correct equation that models the area if x(3x) or 3x² where x is the width of the pathStep-by-step explanation:
Area of a rectangle = Length *Width
Width of the rectangular garden W = 2ft
If the length of the garden is 3 times as long as the width, then length = 3 * width i.e W = 3L
Since Area of the path A = L* W
A = (3W)W
A = 3W²
If the width is the same as x then
Area f(x) = (3x)(x)
According to kyle, the area of his path f(x) = (x + 2)(3x + 2) which is wrong because of kyle addition of 2 to each of the value of the length and width respectively which kyle shouldn't have added any value to the dimension to the garden

An office and apartment building is made up of modules. Each module is a rectangular prism. The building has 150 modules, and is 15 stories high. If all of the modules were divided evenly among the number of stories, how many modules would be on each floor? How many different rectangular prisms could be made from that number? If all of the modules were divided evenly there would be modules on each floor. different rectangular prisms could be made from the number of modules on each floor: × 1 × 1 and 2 × × 1.
Answer:
Part 1. 10 modules per floor
Part 2. Two different rectangular prism
Step-by-step explanation:
Let
x ----> the number of modules
y ---> the number of stories
we have
x=150\ modules\\y=15\ stories
Divide the number of modules by the number of stories
so
\frac{x}{y}=\frac{150}{15}=10\ \frac{modules}{floor}
