Answer:
279 patches can be made.
Step-by-step explanation:
Evaluate the total area of the rectangular piece of fabric, therefore:
Area= l*w = 15*9=135
There are 31 pieces, so the total area is 135* 31 =4,185 square centimeters.
Evaluate the number of triangles that can be made dividing the total area by the area of 1 triangular piece, therefore:
n= 4,185/15=279
So the answer is 279 triangles can be made.

4(1 - x) + 3x = - 2(x + 1)
Answer:
X=-6
Step-by-step explanation:
4(1−x)+3x=−2(x+1)
(4)(1)+(4)(−x)+3x=(−2)(x)+(−2)(1)(Distribute)
4+−4x+3x=−2x+−2
(−4x+3x)+(4)=−2x−2(Combine Like Terms)
−x+4=−2x−2
−x+4=−2x−2
Step 2: Add 2x to both sides.
−x+4+2x=−2x−2+2x
x+4=−2
Step 3: Subtract 4 from both sides.
x+4−4=−2−4
x=−6
Answer:

If the volume of a sphere inscribed in a cubic box is 36pi, find the surface area of the box
Answer:
Surface area of the cube = 216 square units
Step-by-step explanation:
Let the length of a side of a cube = x unit
Diameter of the sphere inscribed in this cube = length of a side of the cube
Volume of the sphere = [tex]\frac{4}{3}\pi r^{3}[/tex]
Where r = radius of the sphere = [tex]\frac{x}{2}[/tex] units
36π = [tex]\frac{4}{3}\pi (\frac{x}{2})^{3}[/tex]
36π = [tex]\frac{4x^{3}\pi }{24}[/tex]
36×24 = 4x³
x = [tex]\sqrt[3]{\frac{36\times 24}{4} }[/tex]
x = 6 units
Length of a side of the cube = 6 units
Surface area of the cube = 6×(Side)²
= 6×(6)²
= 216
= 216 square units

The volume of a solid cylinder is 1584 cubic cm and its height is 14 cm. The radius is
Answer: 6 cm
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder (V): π x radius ² x height
Replacing with the values given and solving for v (Volume)
1584 = π x r ² x 14
Solving for r:
1584 / (π x 14) = r²
36.01 = r²
√36.01 = r
6 cm = r
In conclusion, the radius of the cylinder is 6 centimeters.
Feel free to ask for more if needed or if you did not understand something.
Answer:
The radius is 6 cm
Step-by-step explanation:
To solve this, we will follow the steps below:
write down the formula for finding the volume of a cylinder
volume of a cylinder =πr²h
from the question volume of the cylinder = 1584 cm²
height = 14 cm
substitute the formula and solve for r
π is a constant and is ≈ 3.14
1584 = 3.14×r²×14
1584= 43.96 r²
divide both-side of the equation by 43.96
36≈ r²
take the square root of both-side
√36 = √r²
6 = r
r = 6cm
The radius is 6 cm

435.3 mg
211.6 mg
31.3 mg
15.6 mg
Help please I’ll make you the brainliest if right
Answer:
15.6 mg
Step-by-step explanation:
First 4 s- 500/2= 250 mg
After 8 s- 250/2= 125 mg
After 12 s- 125/2= 62.5 mg
After 16 s- 62.5/2= 31.25 mg
At 20 s- 31.25/2= 15.625 mg
The milligrams of a 500 mg sample will remain at 15.625 mg.
We have given that,
5.6 mg
Radon-219 has a half-life of about 4 s.
What is the sample?A sample refers to a smaller, manageable version of a larger group. It is a subset containing the characteristics of a larger population.
After 20 s,
First 4 s- 500/2= 250 mg
After 8 s- 250/2= 125 mg
After 12 s- 125/2= 62.5 mg
After 16 s- 62.5/2= 31.25 mg
At 20 s- 31.25/2= 15.625 mg
Therefore, the milligrams of a 500 mg sample will remain 15.625 mg.

What is the slope of the line given by the equation y= -3x
Answer:
-3
Step-by-step explanation:
The given equation is in slope intercept form.
The form is y=mx+b
This is where "m" is the slope, and "b" is the y intercept.
So in this equation, m=-3.
Therefore, the slope is -3.

In 2005 a house was purchased for $280,000 and
in 2013 it was sold at $334,000. Assuming that
the value of the house increased at a constant
annual rate what will be the price of the house in
the year 2018?
Given that in 2005 a house was purchases for 280,000 and was later sold in 2013 for 334,000, determine the increase value of the house and what the price of the house will be in 2018.
First, we subtract the two values of the house on both dates.
334,000 - 280,000 = 54,000
Then, divide the difference by the amount of years from 2005 to 2013.
54,000/8 = 6,750
Since, it says the value increases at a constant rate, this indicates that it is a linear function.
So, the linear function would start at 280,000 as the y-intercept and the slope is 6,750.
Linear Function: y = 6750x + 280,000
Lastly, to find the price of the house in 2018, we just need to plug in 13 for x since x represents the years.
y = 6750x + 280,000
Plug in 13 for x.
y = 6750(13) + 280,000
y = 87750 + 280,000
y = 367,750
Thus, the value of the house in 2018 is $367,750.

Linda is building steps for her porch. What is the volume of the steps?
144,000 cm3
288,000 cm3
324,000 cm3
540,000 cm3
Answer:
The volume of the steps is:
324,000 cm3Step-by-step explanation:
Remember that the volume regularly is:
Volume = height * width * depth.There are many forms to solve this exercise, but I'll show you two:
1. Imagine that aren't steps but a big solid, then its volume would be:
Volume of big solid = 60 cm * 60 cm * 120 cm Volume of big solid = 432000 cm3Now you can subtract the volume of a small solid with measures 30 cm * 30 cm * 120 cm (where is the blank for the step):
Volume of a small solid = 30 cm * 30 cm * 120 cm Volume of a small solid = 108000 cm3Now you subtract:
Volume of the building steps = 432000 cm3 - 108000 cm3 Volume of the building steps = 324000 cm32. The building steps are formed by three solid with volume 30 cm * 30 cm * 120 cm, so:
Volume of the building steps = 3 (30 cm * 30 cm * 120 cm) Volume of the building steps = 324000 cm3The sum of three consecutive integers is 915. What are the integers?
A. 304, 306, 308

C. 300, 300, 315
D. 304, 305, 306
Answer:
304,305,306
Step-by-step explanation:
x +x+1+x+2=915
3x+3=915
3x=915-3
3x=912
x=304
The three consecutive integers are 304, 305 and 306, option D is correct.
What is Number system?A number system is defined as a system of writing to express numbers.
Let the three consecutive numbers be x, x+1 and x+2
Sum of three consecutive integers is 915.
x+x+1+x+2=915
3x+3=915
Subtract 3 on both sides
3x=912
Divide both sides by 3
x=304
Hence, the three consecutive integers are 304, 305 and 306, option D is correct.

At the beginning of the month, a rain barrel contained 12 ounces of water. At the end of the month there are 8 1/4 cups of water in the rain barrel.
How many cups of rain water were added to the barrel during the month?
Answer:
The cups of rain water that were added to the barrel during the month is:
6.75 cups.Step-by-step explanation:
First, you must know the conversion units between ounces and cups:
1 cup = 8 ounces.Then, at the beginning of the month, the rain barrel contained 12 ounces, what is in cups:
1 cup = 8 ounces. X = 12 onces.We operate:
X = (12 * 1) / 8 X = 1.5 cupsNow, how at the end of the month there are 8 1/4 cups of water in the rain barrel, in a decimal number it is equal to:
8 1/4 cups = 8.25 cupsTo know what is the cups of rainwater were added to the barrel during the month, you must subtract the number of cups at the beginning of the month to the number of cups at the end of the month:
Cups of rainwater that were added = 8.25 cups - 1.5 cups Cups of rainwater that were added = 6.75 cups.Answer:

Angle B: 50°
Angle C: 90°
Side A: 14
Side B: 12
Side C: 11.2 or 11 if you round to the nearest whole number.
Step-by-step explanation:
Angle A;
Since we know angles B and C we can use those to help us find angle since all three angles should add up to 180°.
90-50=40
Angle A= 40°
Side C;
Since we know all the angles now and the other two side lengths, we will use those to help us find Side C.
cos 40°= C/14
C/14= cos 40°
C/14= .8
C= .8 x 14
C= 11.2
