Answer:

should just be 4/6 or 2/3 simplified lol

Step-by-step explanation:

ratios and fractions are very similar, just pronounced differently. 4:6 is read as "four to fix" while 4/6 is read as "four sixths". only difference is the punctuation

Rewrite the following expression without using absolute value. I3-√4I

nataly862011 [7]

Hey there!

$\mid 3-\sqrt{4} \mid$

Square root of four is positive or negative 2.

$\mid 3 - \pm 2 \mid$

So we have:

$\mid 3-2 \mid$ or $\mid 3+2 \mid$

Add or subtract.

$\mid 1 \mid$ or $\mid 5 \mid$

Simplify the absolute value bars.

1 or 5

Hope this helps!

Find: (4x2y3 + 2xy2 – 2y) – (–7x2y3 + 6xy2 – 2y) Place the correct coefficients in the difference.

DanielleElmas [232]

Answer: Our required answer will be

$11x^2y^3-4xy^2$

Step-by-step explanation:

Since we have given that

$(4x^y^3+2xy^2-2y)-(-7x^2y^3+6xy^2-2y)$

We need to get the difference:

1) We first open the second bracket and make appropriate change in signs :

$4x^y^3+2xy^2-2y+7x^2y^3-6xy^2+2y$

2) Gather the like terms together :

$4x^2y^3+2xy^2-2y+7x^2y^3-6xy^2+2y\\\\=4x^2y^3+7x^2y^3+2xy^2-6xy^2-2y+2y\\\\=11x^2y^3-4xy^2$

Hence, our required answer will be

$11x^2y^3-4xy^2$

P(3) has a 10% chance (given)

P(1) or P(6): Add the two percentages together => 5 + 20 = 25%

P(not a 2): Subtract the percentage for 2 (25%) from 100% => 100 - 25 = 75%

The sum of three consecutive numbers is 72 what is the smallest of the numbers

mylen [45]

Answer:

Step-by-step explanation:

Suppose,

the first number = x

the second number = x+1

the third number = x+1+1 = x+2

Question wise,

x+x+1+x+2 = 72

3x+3 = 72

3x = 72-3 = 69

x = 69/3 = 23

so the numbers are,

23,(23+1)=24 and (23+2)=25

Find the area of each circle, to the nearest tenth. <br><br> r =6.3

Firdavs [7]

Area of Circle = πr^2

Since we know that r=6.3:

π(6.3)^2=39.69 π=124.690

So, the area would be 124.690.
