Answer:

1. 9461000000000

move the desimal in 9.461 12 places to the right to get:

9461000000000

2.

5.85 x 10^-3,

2.5 x 10^-1,

3.6 x 10^8,

8.5 x 10^8,

8.5 x 10^12

the smallest exponent is the smallest. Since 8.5 x 10^8 and 3.6 x 10^8 have the same exponent, go to the desimal

5/6 - 2/3 divide by 4/5
ollegr [7]

Answer:

5/24

Step-by-step explanation:

Start with the first part of the probelm 5/6 - 2/3

You need to find a common denominator of 6 and 3

common denominator= 6

so change 2/3 to 4/6

now you can subtract the top values

5/6-4/6

5-6=1

keep the denominator the same

= 1/6

Now divide 1/6  by 4/5

to divide you are going to multiply by the reciprocal so instead of 4/5 we are going to flip it to 5/4

1/6 x 5/4

5x1=5 and 6x4=24

= 5/24

I WILL GIVE BRAINLIEST to who answers this question correctly.

You start counting from 0 onwards:

C = 6
D = 8

Then C x D = 48

So the product CxD is situated at 48 units from 0

Simplify\:\sqrt[3]{27x^{15}}y^{24}
Free_Kalibri [48]

Answer:

3x^{5}y^{24}

Step-by-step explanation:

\sqrt[3]{27x^{15}}y^{24} =

= \sqrt[3]{3^3x^{15}}y^{24}

= (3^3x^{15})^{\frac{1}{3}}y^{24}

= (3^3)^{\frac{1}{3}}(x^{15})^{\frac{1}{3}}y^{24}

= 3^{3 \times \frac{1}{3}}x^{15 \times \frac{1}{3}}y^{24}

= 3^1x^{5}y^{24}

= 3x^{5}y^{24}

Ratio of 2:3 white flour to whole wheat flour to total of 10 cups flour
LenaWriter [7]
White flour makes up 2 / (2+3) of the total 10 cups:  2/5 of the total 10 cups.

2/5 times 10 is 4 cups.

You'll need 4 cups white flour and 6 cups whole wheat flour, making a total of 10 cups of flour.
