what is hcf of 5 and 0 ?
if you are correct then you're a genius
Answer: Factor of 0
For example, 5 × 0 = 0 so it is true that 0 ÷ 5 = 0. In this example, 5 and 0 are factors of 0. GCF(5,0) = 5 and more generally GCF(k,0) = k for any whole number k. However, GCF(0, 0) is undefined.
Step-by-step explanation:
Answer:
Find the LCM
The LCM of
0,5 is 5.
Greatest common divisor is the largest number which divides two given numbers say 'a' & 'b'
Now let's say a=0 and b= 5
We know that: anything × 0 =0
Therefore 0÷5=0
In other words 5 is a divisor of 0
and 5 is the largest number which divides 5...
Therefore 5 is the greatest common divisor of of 0 and 5Or gcd(5,0)=5
Common divisors of 0 and 5 = 1,5 [0=1*0 ; 5=1*5] and [0=5*0 ; 5=5*1]

Kara has 4/5 gallon milk, she gives some to her brother. Now she 1/3 gallon of milk. How much milk, in gallons, did she give to her brother
Answer:
7/15 of a gallon
Step-by-step explanation:
Her starting amount 4/5 is equivalent to 12/15. Her ending amount 1/3 is equal to 5/15. So subtract her end amount from her starting amount to find how much she gave to her brother. 12/15 - 5/15 = 7/15.
Which equation does not represent a function?
A y= 4
C y = x – 4
B y = x2 - 4
B
D x2 + y2 = 4
Answer:
D x2 + y2 = 4
Step-by-step explanation:
The following are the functions
y = 4
y = x - 4
y = x^2 - 4
but
x^2 + y^2 = 4 is not a function as there should be minimum one x value with two or more y values
But the above equation does not meet the criteria so this represent non-function

1 7/8 quarts of grape juice are required.
5. John wants to make a scale drawing of a Dodge Viper. The length of the car is
approximately 9.5 feet. If he used a scale of 1 inch = 2 feet then what would the
length of the car be in the drawing?
Answer:
2.375 inches
Step-by-step explanation:
for every 2 feet, that is equivalent to 0.5 inches in the drawing. so count how many 2 feet in 9.5 feet first. there are 4.75.
mutiply 4.75 now by 0.5
that is 2.375 in inches

Given:
The focus of the parabola is at (-4,8).
The directrix is at x=-6.
To find:
The equation of the parabola.
Solution:
The directrix is at x=-6, which is a vertical line. So, the parabola is horizontal.
The equation of a horizontal parabola is
[tex](y-k)^2=4p(x-h)[/tex]
Where, (h,k) is vertex, (h+p,k) is focus and x=h-p.
The focus of the parabola is at (-4,8).
[tex](h+p,k)=(-4,8)[/tex]
[tex]h+p=-4[/tex] ...(i)
[tex]k=8[/tex]
The directrix is at x=-6.
[tex]h-p=-6[/tex] ...(ii)
Adding (i) and (ii), we get
[tex]2h=-10[/tex]
[tex]h=-5[/tex]
Putting h=-5 in (i), we get
[tex]-5+p=-4[/tex]
[tex]p=-4+5[/tex]
[tex]p=1[/tex]
Putting h=-5, k=8 and p=1 in the standard form of the parabola.
[tex](y-8)^2=4(1)(x-(-5))[/tex]
[tex](y-8)^2=4(x+5)[/tex]
Therefore, the required equation of the parabola is [tex](y-8)^2=4(x+5)[/tex].

x=[tex]\frac{(y-8)^{2}-20 }4}[/tex]

30-60-90 triangle..find the value of x?
Answer:
A. y = 9√3
Step-by-step explanation:
The relationship of the sides of the triangles are as follows:
First leg = x
Second leg = x√3
Hypotenuse = 2x
Since we know the first leg is 9, multiply that by √3.
Therefore, y = 9√3.
14 less than the quantity k times 6
(Write it as an algebraic expression)
Answer:
6k-14
Step-by-step explanation:
The algebraic expression for inequality is 14 < 6k.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have the statement
14 less than the quantity k times 6
Now, k times 6 = 6k
and, 14 less than k times 6 can written into mathematical form as
14 < 6k
k > 14/6
k> 7/3.

349 + 4.80n
3
135
Step-by-step explanation:
1
For this, use the equation I gave you above to find the costs.
2
First, the cost of the printer will NOT change, for the number of printers Eddie needs to buy does not change, he only needs one. This already helps you figure out that 349 is not a coefficient to the variable, n. However, when it comes to the number of blank shirts Eddie needs to buy, the number of he gets does change, this is the dependent variable that makes the cost vary. Using the equation above, you can plug in any number.
For example, 20.
349 + 4.80(20) = 445
3
For this final part, I just kept using the equation until I got the closest number that is lower than 1000. In this case, 135 got me 997, and 136 was just a few decimals away from 1000, but it was still over.

Matthew invested $5,300 in an account paying an interest rate of 2.1% compounded annually. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $6,020?
Answer: it would be 6
Step-by-step explanation
Delta math
Based on the information for the value of the account to reach $6,020? given it will take 6 years.
Value of account:Let x represent the number of years
(2.1%×5,300)x+5,300=6,020
111.3x+5,300=6,020
Collect like terms
111.3x=6,020-5,300
111.3x=720
Divide both side by 111.3x
x=720/111.3

he perimeter of parallelogram ABCD is 80 cm. AD is 7 cm more than twice AB. Find the lengths of all four sides of ABCD.
Answer:
AB = 11
BC = 29
DC = 11
AD = 29
Step-by-step explanation:
First, draw out and label the parallelogram ABCD. I've done so for you below:
Now, to figure out what to label the sides, refer to:
AD is 7 more than twice AB.
"Than" means that whatever we write, we flip it. For example, 7 more then 5 would be 5+7. Though this may not be important for addition, it is for subtraction. For example, 7 less than 5. This would be 5-7, but if you wrote it wrong, it would be 7-5.
"Is" is key word for "=". So:
AD = 7 more than twice AB.
"Twice" means "two times." So:
AD = 7 more than 2(AB).
AD = 2(AB) + 7
Let's label AB as x.
If the perimeter is 80, then that means AD+AB+BC+DC=80.
We know that in a parallelogram, opposite sides are congruent. So:
AD+AD+AB+AB=80
(2x+7) + (2x+7) + x + x = 80
2(2x+7) +2x = 80
4x + 14 + 2x = 80
6x + 14 = 80
6x = 66
x = 11
AB = 11
AD = 2x + 7
= 2(11) + 7
= 22 + 7
= 29

A field is in the form of a rhombus having each side 81 m and altitude 25 m. What is the side of a square
field which has the same area as that of the rhombus?
Answer:
the side of a square is 45 m
Step-by-step explanation:
The computation of the side of the square field that contains the similar area as compared with rhombus is given below:
As we know that
Area of rhombus = Base × Altitude
= 81 × 25
= 2025
And, area of Square = Side × side
2025 = side^2
side = √2025
= 45m
Hence, the side of a square is 45 m
