Answer 1

Answer:

[tex]x {}^{3} \sqrt{54 {y}^{11} } [/tex]

Answer 2
Given: √54x^6•y^11

Factor 9•6 out since 9•6=54

√9•6x^6•y^11

Factor x^6 to x^2•x^2•x^2 and y^11 to (y^2)^2 • (y^2)^2 • y^2•y

√9•6x^2•x^2•x^2 •(y^2)^2 • (y^2)^2 • y^2•y

Remember that √a•b = √a•√b, so all these exponents that are squared will cancel out because if you square a number and then take the square root, you have the same number. For example, 6^2=36 and √36=6.

3•x^3•y^5√6y

The difference between two positive numbers is 40 and the ratio of these integers is 1:3.Find the integers.

Answers

Answer:

the two integers are 20 and 60

Step-by-step explanation:

Let x and y be two positive numbers ,where x < y.

• The difference between the two positive numbers x and y is 40.

 Means

y - x = 40

• the ratio of these integers is 1:3

 Means

y = 3x

We obtain these two equations:

y - x = 40

y = 3x

Solving the system of equations by substitution :

y - x = 40

y = 3x

⇔

3x - x = 40

y = 3x

⇔

2x = 40

y = 3x

⇔

x = 20

y = 3 × 20 = 60

THE ANSWER WOULD BE
B IS THE CORRECT ANSWER

Please hurry will give braliny

Answers

Answer: D

Step-by-step explanation:

Follow the PEMDAS rule.
It’s not A, because when you solve 2^2 and sq rt of 4, the square exponent and the square root cancels out, so it’s simply 2 x 4. Then you follow by doing division and multiplication, 45/5 is 9 and 2 x 4 is 8, so 9+8=17.

It’s not B, because first solve the numbers in the parentheses. 2^2 is 4, 5+4 is 9. Then solve the square root of 4 which is 2, and you get 45/9x2, which is 10.

It’s not C because 2^2 is 4 and sq rt of 4 is 2, and 4-2 is 2. Then divide 45 by 5 to get 9, and 9+2 is 11.

The correct answer is D, because when you solve 2^2 which gives you 4 and add that to 5, you get 9. The sq rt of 4 is 2, so you get 45/9-2, which is 3.

Hope this helps!

The answer is D. Checked by a calculator

Use the fact that 13x17=221 to find the following and explain how you found each solution

13 × 1700

13 × 17× 100

221 × 100

22100

So the answer is 22100

(13 x 17 = 221) given info

13 x 1.7 =22.1

130 x 17 =2210

13 x 1700 = 22100

Explanation: i believe your learning about how to move your decimal place. If you see the given information 17 is the number we are looking at. When the first equation comes up, there’s a decimal making 17 -> 1.7 . Then you move the decimal in the other direction making the 17. turn to 170. then 1700. Making your answer 22100

Answer:

d) 7(30 + 9) = 7(30) + 7(9)

Step-by-step explanation:

Distributive method:

a(b + c) = ab + ac

Here given:

7 × 39

Among the option's:

1st option (7 + 3) (7 + 9) is wrong, changes final answer.

2nd option (7 × 30) + 9 is wrong, changes final answer.

3rd option 39 × 7 shows commutative property of multiplication.

4th option show distributive method.

It would be the 4th answer. It is the only choice that shows the 7 being distributed onto the 30 and 9 and it still gives you the right answer
