The cube volume is 1000cm find the all face area
A. 200cm
B. 300cm
C. 500cm
D. 600cm
Answer:
D. 600 [tex]cm^{2}[/tex]
Step-by-step explanation:
Volume of a cube = [tex]s^{3}[/tex] = 1000, s = [tex]\sqrt[3]{1000} =10[/tex]
So, the side length is 10 cm
Surface area of a cube is 6[tex]s^{2}[/tex] where s is the side length
so [tex]s^{2}[/tex] = [tex]10cm^{2} = 100 cm^2[/tex]
6*100[tex]cm^{2}[/tex] = 600 [tex]cm^{2}[/tex]
So the answer is D. 600 cm (it should have a little superscript 2 next to it)

A wall in a classroom has a length of 16 ft and a diagonal of 20 ft. A student is painting a rectangular mural on the wall. The mural has a length of 6 ft and a diagonal of 10 ft. What is the difference between the width of the wall and the width of the mural?
ill mark you brainliest pls help!
Answer choices:
A. 2ft
B. 4ft
C. 10ft
D. 14ft
Answer:
B. 4 ft
Step-by-step explanation:
First, find the width of the wall.
The length, width, and diagonal form a right triangle, where the diagonal is the hypotenuse and the length and width are the 2 legs.
Use the pythagorean theorem and solve for a, the width of the wall.
a² + b² = c²
a² + 16² = 20²
a² + 256 = 400
a² = 144
a = 12
So, the width of the wall is 12 feet.
Solve for the width of the mural. Again, the diagonal, length, and width form a right triangle.
Use the pythagorean theorem again and solve for a, the width of the mural:
a² + b² = c²
a² + 6² = 10²
a² + 36 = 100
a² = 64
a = 8
So, the width of the mural is 8 feet.
Now, find the difference between the widths of the wall and mural:
12 - 8
= 4
So, the difference between the two widths is B. 4 ft

Answer:
mario paid 15,000$ for his car
Answer: $15,000
Step-by-step explanation:
This is basic proportions.

Using the formula of proportions, we can calculate (9000*100)/60
This gives up 15000
Therfore he paid $15,000 for his car, which is 100% of the price.
How is unit rate related to the linear equation?
Answer:
https://www.khanacademy.org/math/cc-eighth-grade-math/cc-8th-linear-equations-functions/cc-8th-graphing-prop-rel/v/graphing-proportional-relationships-example
Step-by-step explanation:
Answer:
A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled. Because of this, it is also called a direct variation. The equations of such relationships are always in the form y = mx , and when graphed produce a line that passes through the origin. In this equation, m is the slope of the line, and it is also called the unit rate, the rate of change, or the constant of proportionality of the function.

A long-distance runner jogs at a constant speed of 7 miles per hour for 45 minutes. Which spreadsheet formula would give the distance she traveled?
Group of answer choices
A.) =7*45
B.)=7/45
C.)=7*(3/4)
D.)=7/(3/4)
The spreadsheet formula would give the distance runner traveled is =7*(3/4). The correct option is C.
What is speed?The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.
Speed = Distance Covered / Time taken
Given that a long-distance runner jogs at a constant speed of 7 miles per hour for 45 minutes. Therefore, we can write the time and speed as,
Time = 45 minutes = 45/60 hour = 3/4 hour
Speed = 7 miles per hour
Now, the distance that the runner will cover can be written as,
Distance = Speed ×Time
Therefore, on the spreadsheet we can write,
Distance = speed * Time
= 7 * (3/4)
Hence, the spreadsheet formula would give the distance runner traveled is =7*(3/4).

I just want to know deh y numbers .-.
Thx.
Answer:
Look at the image.
Step-by-step explanation:
y = - 3 - 2x
y = - 3 - 2( - 5)
y = - 3 + 10
y = 7
y = - 3 - 2( - 2)
y = - 3 + 4
y = 1
y = - 3 - 2( - 1)
y = - 3 + 2
y = - 1
y = - 3 - 2(2)
y = - 3 - 4
y = - 7

Answer:
There are 6 fiction books in the bin. The probability of randomly selecting a fiction book from the bin is 0.6 or 3/5.
Step-by-step explanation:
The third bullet point says that the probability of selecting a poetry book is 1/5, and the second point says that the probability of selecting a fiction book is three times as likely than the poetry books. So that would mean we must multiply 1/5 by 3. So do that you could turn it into a decimal first. 1/5 as a decimal is 0.2. Next, we multiply it. So 0.2 times 3 equals 0.6. Therefore the answer is 0.6. And to convert that back to a fraction, it would be 3/5.

(a) What is 0. 36 expressed as a fraction in simplest form? (line over 36)
(b) What is 0.36 expressed as a fraction in simplest form? (line over 6)
(c) What is 0.36 expressed as a fraction in simplest form? (no line)
Answer:
I’m sorry if I’m wrong
Step-by-step explanation:
A) 0.36 with a line over both 36 means as a decimal the 36 repeats, so it would look like 0.363636
as a fraction it would be 36/99, divide both numbers by 9 to get 4/11
B) 0.36 with the line over the 6 means just the 6 repeats so it would look like 0.3666
as a fraction that would be 33/90 , divide both by 3 to get 11/30
C) 0.36 would be 36/100, divide both numbers by 4 to get 9/25

Find the constant of proportionality for the table of values and write in the form y = kx
A) y = 1/4x
B) y = 4x
C) y = 6x
D) y = 24x
Answer:
Option 'B' is correct.
Step-by-step explanation:
Since we have given that
Number of lemons used is denoted by 'y'.
Number of glasses of lemonade is denoted by 'x'.
As we can observe that ,
[tex]\frac{6}{24} = \frac{8}{32} = \frac{7}{28} = \frac{2}{8} = \frac{4}{16} = \frac{1}{4} \\[/tex]
so we can write i as
[tex]\frac{x}{y} = \frac{1}{4}[/tex]
By cross multiplication
y=4x
So, if write it in the form y=kx,
It will be y=4x.
There is approximately 0.62 km in 1 mile. If you walk 12.5 miles, how many kilometers did you walk?
Answer:
Approximately 8.125 km
Step-by-step explanation:
The ratio 0.62 : 1 is equal to the ratio 8.125 : 12.5
To get this answer
Multiply both sides of the ratio by 12.5. 0.62(×12.5) : 1(×12.5)Your answer will be 8.125 : 12.5The final answer would be 8.125 km : 12.5 miles.2.2 ≤ 2.25 true or false?
True,
2.2 is equal to 2.2 Imagine it like this.
22 < 225 correct right? Well look at this 22<22 is wrong it should be equal, so we added on a five to make it more greater!
Answer:
false
Step-by-step explanation:
≤ means greater than or equal to. 2.25 is greater than 2.2, there isn't a possibility that 2.2 is greater than 2.5 even if it was estimated 2.4 would be the greatest number, hence the use of ≤ is invalid.
