Answer:

The answer is (b) ⇒\frac{d^{5} }{2\sqrt{c} }

Step-by-step explanation:

∵ \frac{\sqrt{c^{2}d^{6}}}{\sqrt{4c^{3}d^{-4}}}

∵ √x² = x ⇒ that means to cancel the square root divide

  the power by 2

∴ \sqrt{c^{2}d^{6}}=cd^{3}

∵ √4 = 2 ⇒ √2×2 = √2² = 2

∵ √c³  = c^{\frac{3}{2}}

∴ \sqrt{4c^{3}d^{-4}}=2c^{\frac{3}{2}}d^{-2}

∴ \frac{cd^{3}}{2c^{\frac{3}{2}}d^{-2}}

∵ In the same base with multiplication we add the power,

  in same base with division we subtract the power

∴ \frac{1}{2}c^{1-\frac{3}{2}}d^{3-(-2)}=\frac{1}{2}c^{\frac{-1}{2}}d^{5}=

  \frac{d^{5}}{2c^{\frac{1}{2}}}=\frac{d^{5}}{2\sqrt{c}} ⇒  c^{\frac{1}{2}}=\sqrt{c}

∴ The answer is (b) ⇒ \frac{d^{5}}{2\sqrt{c}}

Kenny rented an SUV for 3 days and drove it 430 miles. The daily rate was $46.99 and $0.35 per mile with the first 50 miles bein
elena-14-01-66 [18.8K]

Answer:

Rental charge is $273.97

Step-by-step explanation:

Given that Kenny rented an SUV for 3 days and drove it 430 miles. The daily rate was $46.99 and $0.35 per mile with the first 50 miles being free. we have to find the rental charge.

Total miles which drove are 430 miles.

Given that first 50 miles are free ∴ the charged miles are 430-50=380 miles

Cost of 1 mile given is  $0.35

Cost for 380 miles is $0.35\times 380=$133

The daily rate was $46.99 therefore for three days 3($46.99)=$140.97

Hence, the total charge is = Cost for 380 miles + Daily rate for 3 days

                                           = $133+$140.97 =$273.97

if p is a prine number greater than 5 and q is an odd number greater than 5 whihc of the following is true
bearhunter [10]

The first statement p + q is not a prime number is a true option (A) correct.

<h3>What is the number?</h3>

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

First statement:

p + q is not a prime number.

Let p = 7

q = 9

= 7 + 9 = 16 (16 is not a prime)

= 7×9 = 63 (no factor of 63)

p = 7, q = 7

q/p = 7/7 = 1 (1 is integer)

Thus, the first statement p + q is not a prime number is a true option (A) correct.

Which numbers between 10 and 99 have digits that differ by 4 and add to 6
madreJ [45]

Answer:

A

Step-by-step explanation:

Correct option is A)

Let a 3-digit number ABC

Case (1)

If A=7, then B  and  C can be any digit but not 7

so, total 9 digits (0,1,2,3,4,5,6,8,9) can replace B and C

Then total such combinations =1(9)(9)=81

Case (2)

If B=7  then A can be any digit but not  0 and 7, because if A=0 it will be a 2-digit number.

And C can be any digit but not 7

Then total combinations =(8)(1)(9)=72

Case (3)

If C=7  then A can be any digit but not 0 and 7, because if A=0 it will be a 2-digit number.

And B can be any digit but not 7

Then total combinations =(8)(9)(1)=72

So, total numbers between 99 and 1000 which have exactly one of their digits as 7 are =81+72+72=225
