1+4=5 2+5=12 3+6=21 8+11=?

Answers

Answer 1

Answer: 40. This is because:
1+4= 5.
2+5= 7. Now you must take the 5 from the previous answer and add it to your new answer, which then gives you 12.
Now 3+6=9. Take 12 and add it to 9, which will give you 21. Follow the pattern to get the next answer, which is 40.

What fractions are equivalent to 6/15

Answers

$(6)/(15)= (6/3)/(15/3)= (2)/(5)$

$(6)/(15)=(6\cdot2)/(15\cdot2)= (12)/(30)$

$(6)/(15)=(6/100)/(15/100)= (600)/(1500)$

To obtain an equivalent fraction, you have to multiply or simplify that fraction.

one fraction is 2/5.

Find three different ratios that are equivalent to 7:3

Answers

Answer:

14 : 6, 21 : 9 and 28 : 12

Step-by-step explanation:

Given ratio,

7 : 3

Since, when we multiply both numerator and denominator by a same number then we get an equivalent fraction,

That is,

$(7)/(3)=(7* 2)/(3* 2)=(14)/(6)$

$(7)/(3)=(7* 3)/(3* 3)=(21)/(9)$

$(7)/(3)=(7* 4)/(3* 4)=(28)/(12)$

Hence, the different ratios that are equivalent to 7:3 are,

14 : 6, 21 : 9 and 28 : 12

Answer:

14:6

21:9

28:12

Step-by-step explanation:

Given the initial ratio of 7:3, you can find equivalent ratios by multiplying the two numbers by the same factor:

7 x 2 = 14

3 x 2 = 6

14:6

7 x 3 = 21

3 x 3 = 9

21:9

7 x 4 = 28

3 x 4 = 12

28:12

Name 2 strategies that you can use to find the area of a shape

Answers

1. Multiply the dimensions

2. Make two smaller shapes and multiply each dimensions then add the answers together to get the final answer

First, it depends what shape it is.

To find the area of the:

square/rectangle: L x W (length times width)\

Triangle: 1/2 x b x h (One half times base times height)

Parallelogram: b x h (base times height)

Circle: $\pi$ x r^2 (Pi times radius to the power of 2)

Trapezoid: 1/2 x (a+b) x h (One-half times Base 1 plus Base two times height

Disclaimer: These are the areas for MOST shapes, not all.

hope this helpeed :)
