Are 2/7 and 6/21 equivalent ratios

Answers

Answer 1

Answer:

To find the ratios are equivalent or not, we need to take out the difference between the two ratios.

Equivalent Ratio

Two ratios are equivalent ratios if there difference is zero, or we can say that the two ratios are equivalent ratios if they are in the same proportion to each other.

For example,

$(1)/(2)=(2)/(4)=(3)/(6)= (50)/(100)$

$(2)/(7)$ and $(6)/(21)$ ratios are equivalent ratios.

Given to us

$(2)/(7)$

$(6)/(21)$

Solution

If the ratios are equivalent to each other then their difference will be zero.

$(2)/(7)-(6)/(21)\n\n=(2* 3)/(7 * 3)-(6)/(21)\n\n=(6)/(21)-(6)/(21)\n\n= 0$

Hence, $(2)/(7)$ and $(6)/(21)$ ratios are equivalent ratios.

Answer 2

Answer: 6 / 2 = 3
21 / 7 = 3

Yes, 2/7 and 6/21 are equivalent ratios. The second number is simply the first number tripled.

How can you use base ten blocks to find 2.16 divided by 3

Answers

For this question, let's move the decimal number 2 spaces to the right. 2.16-->216You need 21 ten rods and 6 cubes. Why: I wouldn't do 2 hundred flats because 2 isn't divisible by 3.Put the ten rods into 3 equal group, then do the same with the cubes.You should end up with 7 in each group since 21 divided by 3 is 7.You should also end up with 2 cubes in each group.So in one group you have 72. Now move the decimal back to where it came from, 2 spaces to the left. Now you have 0.72.

Final answer:

Using base ten blocks to divide 2.16 by 3 involves representing 2.16 with the blocks, then dividing them into three equal groups. The result is 0.72.

Explanation:

To use base ten blocks to find 2.16 divided by 3, we first represent the number 2.16 using base ten blocks. This can include two 1-blocks, one 1/10-block (which represents 0.1), and six 1/100-blocks (which represent 0.1 each). Then we divide these blocks evenly among three groups, as we're dividing by 3.

Each group would end up with 0.72, as we would distribute the 1-blocks, the 1/10-block, and the 1/100-blocks evenly among the 3 groups. Therefore, 2.16 divided by 3 is 0.72 when using base ten blocks.

What is 18 times 12 for baseball cards

Answers

18*12= 216 cards

I hope that's help:0

18*12=216 baseball cards.
Check this by doing 216/12=18, or 216/18=12.

What is the value of the expression 6+18÷3×4

Answers

Hi! Ok so you use PEMDAS to figure these out.
So first we can cancel out parenthesis and exponents since there are none in this equation.
Now we do multiply and divide from left to right.
So first 18/3=6
So 6+6*4
Now we do 6*4=24
Now add and subtract
Then 6+24=30
So your answer is 30

it would be 30 cuz of the PEMDS
18 ÷ 3 =6
3 × 4 = 24
24 + 6 =30

Please answer!!!! please!!!!!!

The problem here is: Too many words.

If you boil the problem down to the bare facts, the question is:

   "$210 is 15% of what number ?"

I'm pretty sure you can take it from there,
but here's the rest of it anyway:

$210 = 15% of (March amount)

      $210 = 0.15 x (March amount)

Divide each side by 0.15 :   $1400 = March amount .

Check:
1400 + 210 = 1610
1.15 x 1400 = 1610 yay!

Can anyone figure this out ?

Answers

so the question says that x is a multiple of y that means that y times something=x or
yz=x

A. says y is a factor of x
this is true because y times z=x so y is a factor of x

I can't read B and D

C. so it says x if a factor of 2y this might be true or false because if y is 2 and x=20 then 2y=4 and 20 is not a factor of 4
if we have y=2 x=4 then 2y=4 and 4 is a factor of 4

Can't read C and D but A is correct for sure

The area of a triangular garden can be no more than 120 square feet. The base of the triangle is 16 feet. What is the height of the triangle?show your work

Answers

The height of the triangle can not be more than 15 feet.

What is a triangle?

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

Given the triangle,

Base = 16 feet.

Area = 120 feet²

Since the area of a triangle is given as (1/2) × base × height.

So,

Area = (1/2) × base × height.

120 = (1/2) × 16× height

Height = 120/8 = 15 feet

Hence "The height of the triangle can not be more than 15 feet".
