What is the volume of the box if it is scaled down by a factor of
1
10
?
Answers
Answer:
541/2 square
Step-by-step explanation:
What is the volume of the box if it is scaled down by a factor of 1/10
we know that
the volume of the smaller box=[scale factor]³*volume original box
scale factor=1/10
volume original box=5,120 cm³
so
volume of the smaller box=[1/10]³*5,120-----> 5.12 cm³
the answer part 6) is
5.12 cm³

Bobby and Marie are running a lemonade stand.They spend $12 on all their materials and charge $1.50 for each cup of lemonade. If they sell 20 cups of lemonade, how much money would they make(or lose)?
Answers
Answer:
$18
Step-by-step explanation:
First you would multiply $1.50 by how many cups of lemonade they sell (20). Your answer for this would be $30. After that you want to subtract the $12 from the $30, because they spent $12 on materials. Then you get $18, which is your answer. Hope this helps :)

Answers
Answer:
x = 19
Step-by-step explanation:
Here, we want to find the value of x
To get this, we use one of the important circle theorems. This is the theorem of secant segments
We have this that;
8(8 + x)= 9(9 + 15)
64 + 8x = 216
8x =
216-64
8x = 152
x =

x = 19
Steve will roll a number cube, numbered 1-6, twice. What is the probability of rolling a number greater than 4, then
rolling an odd number?
Answers
Answer:
6/36 or 1/6
Step-by-step explanation:
To find the probability of rolling a number greater than 4, then rolling an odd number, you must multiply the probability of rolling numbers greater than 4 by the probability of rolling an odd number. In numbers 1-6, there are two number greater than 4: 5 and 6. The probability of an event is the specific factor over the total amount of results or objects. The probability of rolling a number higher than 4 is 2/6, or 1/3. In numbers 1-6, there are 3 odd numbers: 1, 3, and 5. The probability of rolling an odd number is 3/6, or 1/2. 3/6 times 2/6 is 6/36, and when simplified, it becomes 1/6.

6 + 6y = 18
Since 18 - 6 = 12, y will equal 2.
6 + 6(2) = 18
6 + 12 = 18

Solve the quadratic equation by factoring.
4x² - 20x + 28 = 3
A) x = 5
B) x = 5/2
C) x = 2/5
D) x = - 5/2
Answers
Answer:
B) x = 5/2
Step-by-step explanation:
subtract 3 from each side to get:
4x² - 20x + 25 = 0
this is the difference of 2 squares:
(2x -5)² = 0
one solution, x = 5/2
Answer:
B) x = 5/2
Step-by-step explanation:
4x² - 20x + 28 = 3
Move terms to the left side
4x² - 20x + 28 - 3 = 0
Subtract the numbers
4x² - 20x + 25 = 0
Use the quadratic formula
[tex]x =\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex]
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.
4x² - 20x + 25 = 0
a = 4
b = -20
c = 25
x = [tex]\frac{-(-20)+\sqrt{(-20)^{2}-4x4x25 } }{2x4}[/tex]
Evaluate the exponent
x = [tex]\frac{20+\sqrt{400-4x4x25 } }{2x4}[/tex]
Multiply the numbers
x = [tex]\frac{20+\sqrt{400-400 } }{2x4}[/tex]
Subtract the numbers
x = [tex]\frac{20+\sqrt{0} }{2x4}[/tex]
Evaluate the square root
x = [tex]\frac{20+0 }{2x4}[/tex]
Add zero
x = 20 / 2 x 4
Multiply the numbers
x = 20 / 8
Cancel terms that are in both the numerator and denominator
x = 5/2

Actually Welcome to the concept of Locus of a shape.
Here, the left movement is in x direction and vertical or up movement is in the y direction.
so we get as,
A(1,-2) ==> 1 towards left => 0
and 3 units up => 1
hence the new co-ordinates are A(0,1)
hence, A(0,1) is correct option

Answer:
(x+9)(x-3)
Step-by-step explanation:
Find the number that multiplies to make -27 and adds to make 6. In this case it is 9 and -3. Use these numbers to factorise.
Answer:
(x-3) (+9)
Step-by-step explanation:
To know what numbers to use, factor out the constant (-27).
You would get the numbers : 1,3,9,27.
Then figure out which numbers would make the 6x true. In this case, we would need the 3 and 9. They also need to add up to 6x, so the 3 needs to be negative.
-3 & 9
Then form the factors:
(x-3) (x+9)
