help pleaseee, i really need this

Answer: Please see explanation column for answers

Step-by-step explanation:

When a number  divides into another number without a remainder, it s called a factor of that number.  Lets say we want to  find the common factors of two numbers, we get the  factors of each one and  compare them. The common factor is the one that is found in both lists

While The Highest common factor, is the highest factor number found in both lists.

b) 2b , 3b

Factors of 2b= 1, 2 and b

Factors of 3b=1, 3 and b

Common factors =1 and  b

HCF=1b

e) 5bc, 2c2, 3cd

Factors of 5bc=  1, 5, b, c

Factors of 2c2= 1,  2, c, c2

Factors of  3cd= 1, 3, c, d

Common factors = 1 and c

HCF= 1c

f) 4a2b, 8b2c, 6bcd

Factors of 4a2b=  1, 2, 4, a, a2, b

Factors of 8b2c= 1, 2, 4, 8, b, b2, c

Factors of  6bcd= 1, 2,3,6, b, c,d

Common factors = 1, 2 , b

HCF=  2b

[tex]15:31[/tex]

Step-by-step explanation:

To find the amount of total students, you would do this:

[tex]15+16=31[/tex]

Since there are [tex]15[/tex] girls, the [tex]girls[/tex] to [tex]total students[/tex] ratio would be [tex]15:31[/tex].

Step-by-step explanation:

Can you provide a picture?

Answer: x = pi

sin²x - 2cos x - 2 = 0

⇔ 1 - cos²x - 2cos x - 2 = 0

⇔ cos²x + 2cos x + 1 = 0

⇔ (cos x + 1)² = 0

⇒ cos x + 1 = 0

⇔ cos x = -1

⇒ x = pi + k2pi

because 0 ≤ x < 2pi

=> x = pi

Answer:

The lengths of DF and HI

Step-by-step explanation:

SSS

This means Side Side Side

So to prove this triangle is similar we have to use only true information about the sides.

We can already cross off the second and last answer choices because they are talking about angles.

The first answer choice is about the sides but first we have to determine if its true or not.

Side DF is on the left opposite of angle G

HI is also on the left, opposite of angle I

We can assume those sides are the same but to really know we can check if the other sides match up

We know this constriction has a scale factor of: 1.66666667

If you divide 3.5 by our scale factor you get 2.1

If you divide 5 by our scale factor you get 3

This proves that DG and HJ and FG and IJ would be the matching constricted side

This means that DF and HI would be matching as well making the first answer choice correct.

I hope this helps, don't be afraid to reach out with any further questions! Have a nice day!

Step-by-step explanation: 80%*90=72. 72/90=8/9.

20%*90=18. 18/90=1/5

80% of 90 is the same as 8/9 of 90 is false.

20% of 90 is the same as 1/5 of 90 is true.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, 80% of 90 is the same as 8/9 of 90.

80% of 90 is,

= (80/100)×90.

= 8×9.

= 72.

And,

(8/9)×90.

= 8×10.

= 80.

So, 80% of 90 and 8/9 of 90 is not the same.

20% of 90 is the same as 1/5 of 90.

(20/100)×90.

= 2×9.

= 18.

And,

(1/5)×90.

= 18.

So, 20% of 90 is the same as 1/5 of 90.

Answer and Step-by-step explanation: A Line Segment is a part of a line with two endpoints and fixed length.

The length of segment JL is

JL = [tex]-1-(-10.5)[/tex]

JL = 9.5 units

And of KN:

KN = [tex]4-(-4)[/tex]

KN = 8 units

The term congruent refers to an object, form or figure that have the same shape and size.

Both segments have the same shape (a line), however not the same size. So, segments JL and KN are not congruent.

f(x)/g(x)

(x2-1)/(x-1)

x cannot equal 1 because this would render the denominator, also known as the divisor, as zero.

x can be greater than 1.

If you would like, we can factor the numerator...

x2-1

(x+1)(x-1)

FIRST...(x)(x)=x2

OUTER...(x)(-1)=-1x=-x

INNER...(1)(x)=1x=x

LAST...(1)(-1)=-1

x2-x+x-1

x2-1

So...

f(x)/g(x)=[(x+1)(x-1)]/(x-1)

(x-1) is in the numerator and denominator.  It cancels...

f(x)/g(x)=(x+1)

Answer:

280π units² or 879.645943 units²

Step-by-step explanation:

Let's use the formula for the surface area of a cylinder: 2πrh + 2πr² (r=radius, h=height)

Let's plug in the numbers given now since we can assume h=13 (since side length and height can be the same) while r=10.

2π(13)(10) + 2π(10)²

2π(130) + 2π(10)

260π + 20π

Answer:

One bottle of soap will hold 3/8

Step-by-step explanation:

3/4= The amount of soap she has in total

3/4= 6/8 which is the same amount but now we can divide it by 2

.75 (6/8) divided by 2= .375 (3/8)

So each soap dispenser will have 3.75 liters of soap.

Sentences: To check our work

.375x2= .75

3/4 divided by 2= 3.75

Answer: 2x+y=-8 = x=-1/2y-4          

4x-6y=-24 = x =3/2y-6

Step-by-step explanation:

2x+y=-8 -- Step 1: Add -y to both sides.

2x+y+−y=−8+−y

2x=−y−8

Step 2: Divide both sides by 2.

2x/2=-y-8/2

4x-6y=-24 -- Step 1: Add 6y to both sides.

4x−6y+6y=−24+6y

4x=6y−24

Step 2: Divide both sides by 4.

4x/4=6y-24/4
