Step-by-step explanation:
a whole number has 0 decimal places (after the decimal point, meaning on the right side of the decimal point).
so, all the decimal places (4) must come from the other factor.
a multiplication by a whole number is always a series of additions of the other factor with itself. if anything, such a multiplication eliminates decimal places. it does not create additional ones.
e.g.
3.06 × 5 = 15.3 (because it is actually 15.30, but trailing 0s don't have any value like leading 0s, and are normally skipped).
the increase in the decimal places happens by involving places with higher value : 1/10 has a higher value than 1/100, that has a higher value than 1/1000, and so on.
so, e.g. 0.2×9 = 1.8 (and not 0.18).
as it is 2/10 × 9 = 18/10 = 1.8
an addition cannot create suddenly new decimal places with lower value.
therefore, normally we would say the other factor has 4 decimal places.
but in reality, it is a I said above, the 4 decimal places of the result of the multiplication "come from the other factor".
we cannot say that the other factor has 4 decimal places, because it could have more, and the multiplication with the whole number removed some.
e.g. 3.6 × 5 = 18 (or 18.0).
so,
32.3046 could be 6.46092 × 5
when we think this through, the other factor could have infinitely many decimal places.
like 5/9 × 108 = 0.555555... × 108 = 60
or our number
32.3046 could be 0.2991166666... × 108
so, all we can say, the other factor must have at least 4 decimal places.

What are the solutions to the quadratic equation 4x^2= 64?
Ox=-16 and x = 16
Ox=-8 and x =8
Ox= -4 and X = 4
Ox=-2 and x =2
Answer:
x=4 or -4
Step-by-step explanation:
4 squared is 16, and 4 times 16 is 64
The solution is, the solutions to the quadratic equation 4x^2= 64 are, Ox= -4 and X = 4.
What is Square root?A square root of a number is a value that, when multiplied by itself, gives the number. In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x.
For example, 4 and −4 are square roots of 16, because 4² = ² = 16.
here, we have,
given that,
the quadratic equation 4x^2= 64
now, we have to simplify the equation,
at first, take 4 common from both sides,
we get,
x^2= 16
now, taking square root on both side, we get,
x = ±4
Hence, The solution is, the solutions to the quadratic equation 4x^2= 64 are, Ox= -4 and X = 4.

solve the system of equations by the substitution method.
{ 21x + 7y = 41
{ -3x = y + 6
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A. The solution is __ ( type an ordered pair. Simplify your answer.)
B. There are infinitely many solutions.
C. There is no solution.
Answer:
C. There is no solution.
Step-by-step explanation:
Similarly to the previous question, you want to substitute one of these equations into the other:
21x + 7y = 41
-3x = y + 6
But first, you need to isolate for a variable. I'm going to isolate for y in the second equation to avoid fractions.
-3x = y + 6
y = -3x - 6
Now that I've done that, I can now plug it into the first equation to solve for x:
21x + 7(-3x - 6) = 41
21x + -21x - 42 = 41
0x = 41
0 ≠ 41
Since 0 ≠ 41, these lines are parallel, which means that there are no solutions.
expand and simplify 2(x+7) + 3(x+1)
Let's simplify step-by-step.
2(x+7)+3(x+1)
Distribute:
=(2)(x)+(2)(7)+(3)(x)+(3)(1)
=2x+14+3x+3
Combine Like Terms:
=2x+14+3x+3
=(2x+3x)+(14+3)
=5x+17
your answer is 5x+17

Step-by-step explanation:
We know there is nine hundered and eight so lets put that.
908.
Then we know that there are seven hundredths, one number to the right of a decimal is a tenth, so lets go one more to the right. We put seven to the right of the tenth decimal place. Now we have:

I WILL MARK BRAINLIEST Twelve is added to a number and then the sum is multiplied by 4/5 to give 23.6. What is the number?
Answer: 17.5 or 35/2
Step-by-step explanation:
(If you change 4/5 to a decimal, it makes this easier. 4/5 would be 0.8.)
23.6 = (12 + x)*0.8
23.6 = 9.6 + 0.8x
14 = 0.8x
17.5 = x
17.5 as an improper fraction would be 35/2.

Which inequality represents the graph below?
a y>2x+4
b y>-2x+4
c y>-2x+2
d y<-2x+4
Answer:
B. y > -2x + 4
Step-by-step explanation:
we know it's y greater than (>) because the shaded region is above the line. Its a dashed line because it's >. If it was ≤ or ≥ symbol it would be a bolded straight line not dashed.
We can tell from the graph that the y-intercept is (0,4). the slope is -2

christopher bought a six-pack of soda for 1.50. each can holds 2 fluid ounces. identify the total quantity of each unit in the problem a. cans b. dollars c. cents d. six packs e. ounces f. cases
The total quantity of each unit in the problem is ounces
What is the volume of a can of soda in ounces?
A can of soda weighs about 2 fluid ounces and in pack of soda, there are 2 cans of soda, which means that total quantity of each unit in the problem can be determined in ounces.
Six packs is not a unitary measure, because each pack has 12 cans , which means that six packs translate into 72 cans(6 packs*12 cans), also, the can itself is made of ounces, hence, measuring the unit of soda in cans is not appropriate where each can is about 2 ounces

1.1 Paul leaves from Johannesburg to Limpopo and has to travel 300km to get to his destination: If he travels at a constant speed of 75 km per hour, how many hours will it take him to get there?
1.2 And if he only has 90 minutes to get to his destination, what speed must he travel to get there on time?
Answer:
4 hours ; 200 kmph
Step-by-step explanation:
Given that :
Distance to be covered = 300 km
Speed of travel = 75kmph
Number of hours it will take to get to destination :
Time taken = Distance / speed
Time taken = 300 km / 75 kmph
Time taken = 4 hours
2.) If he has 90 minutes to get to destination, required speed will be ; 90 minutes = 1.5 hours
Speed = distance / time
Speed = 300 km / 1.5 hours
Speed = 200 kmph

Write the next whole number after 6467 in the base-eight system.
Answer:
30541
Step-by-step explanation:
8⁰ = 1
8¹ = 8
8² = 64
8³ = 512
8⁴ = 4096
8⁵ = 32768 > 6467
We have
6467 ÷ 8⁴ = 1 (mod 2371)
2371 ÷ 8³ = 4 (mod 323)
323 ÷ 8² = 5 (mod 3)
3 ÷ 8 = 0 (mod 3)
3 ÷ 1 = 3
=> 6467 in the base-eight system: 30541

A globe of Earth is in the shape of a sphere with a radius of 14 inches. Find its a volume and b surface area.
Round the answers to the nearest hundredth.
Answer:
[tex]Volume = 11488.21[/tex]
[tex]Area = 2461.76[/tex]
Step-by-step explanation:
Given
[tex]Radius, r = 14\ in[/tex]
Shape: Sphere
Solving (a): The Volume
This is calculated as:
[tex]Volume = \frac{4}{3}\pi r^3[/tex]
Take [tex]\pi[/tex] as 3.14 and substitute 14 for r
[tex]Volume = \frac{4}{3} * 3.14 * 14^3[/tex]
[tex]Volume = \frac{4}{3} * 3.14 * 2744[/tex]
[tex]Volume = \frac{4 * 3.14 * 2744}{3}[/tex]
[tex]Volume = \frac{34464.64}{3}[/tex]
[tex]Volume = 11488.21[/tex]
Solving (b): The Surface Area
This is calculated as follows:
[tex]Area = 4\pi r^2[/tex]
Take [tex]\pi[/tex] as 3.14 and substitute 14 for r
[tex]Area = 4 * 3.14 * 14^2[/tex]
[tex]Area = 4 * 3.14 * 196[/tex]
[tex]Area = 2461.76[/tex]

Answer:
9
Step-by-step explanation:
To find the height of a right angular cone, the formula is: [tex]\sqrt{l^{2} - r^{2}}[/tex]
Height = [tex]\sqrt{15^{2} - 12^{2}}[/tex]
= [tex]\sqrt{225 - 144}[/tex]
= [tex]\sqrt{81}[/tex]
= 9
the radius of a cone is 15,the slant height is 12
calculate the height
h = √(s2 - r2)
H=√[12^2-15^2]
H=√ (144-225)
H=√-81
the square root of -81 is not considered as a number
hence,
the - is removed
= √81
=9
