Tasya [4]3 years ago

Answer:

Step-by-step explanation:

\sqrt[4]{(16a^4)^5}=(16a^4)^{\frac{5}{4}} [Since, \sqrt[n]{x}=x^{\frac{1}{n}}]

               =(16)^{\frac{5}{4}}(a^4)^{\frac{5}{4}}

               =(2^4)^{\frac{5}{4}}(a^4)^{\frac{5}{4} }

               =(2^{4\times \frac{5}{4}})(a^{4\times \frac{5}{4}})

               =2^5a^5

\sqrt[5]{(b^{\frac{1}{4}})^6}=\sqrt[5]{b^{\frac{6}{4}}}

           =\sqrt[5]{b^{\frac{3}{2}}}

           =(b^{\frac{3}{2}})^{\frac{1}{5} }

           =b^{\frac{3}{10}}

\sqrt[3]{\frac{c^{15}}{c^9}}=\sqrt[3]{c^{15-9}}

         =(c^6)^{\frac{1}{3}}

         =c^{6\times \frac{1}{3} }

         = c²

\sqrt[4]{16d^6\times 16d^{-5}}=\sqrt[4]{(2)^4(d^{6-5})(2)^4}

                        =\sqrt[4]{2^{(4+4)}d}

                        =\sqrt[4]{(2^8)d}

                        =2^{\frac{8}{4}}d^{\frac{1}{4}}

                        =2^2d^{\frac{1}{4}}

                        =4d^{\frac{1}{4}}

There are 20,000 members of a zoo. The percent of
schepotkina [342]

1500 members have a contributor  membership.

64.8% of the noncontributory  memberships are individual memberships.

<u>Step-by-step explanation:</u>

There are 20,000 members of a zoo.

⇒ Total members = 20,000

From the graph shown,

7.5% of the members have a contributor  membership.

<u>To find the number of members who have contributor  membership :</u>

⇒ 7.5% of 20,000

⇒ (7.5/100) × 20,000

⇒ 7.5 × 200

⇒ 1500 members.

Therefore, 1500 members have a contributor  membership.

<u>To find the percentage of the noncontributory  memberships are individual memberships :</u>

The percentage of noncontributory  memberships = 100% - 7.5% ⇒ 92.5%

The percentage of individual memberships = 60%

∴ What percentage of the noncontributory  memberships are individual memberships ⇒ (60 / 92.5) × 100 = 64.8%

Two boxes are shaped as right rectangular prisms. The larger box is has a length of 24 cm, a width of 10 cm, and a height of 30
Vilka [71]
The dimensions of the smaller box are half those of the larger box. This means that:
*Length of smaller box= length of larger box/2= 24/2= 12cm.
*height of smaller box= height of larger box/2= 30/2= 15cm.
*width of smaller box= width of larger box/2= 10/2= 5cm.
