The product of the given two fractions are rational.

The given fractions include;

2/2 and 4/18

The product of the given fractions is calculated as follows;

$\frac{2}{2} \times \frac{4}{18} = \frac{2}{9}$

A rational number is a number that can be expressed in ratio form. These numbers are two integers expressed in form of fractions called numerator and denominators.

Irrational numbers cannot be expressed in form of simple ratios.

Thus, we can conclude that the product of the given two fractions are rational.

Rewrite the root expressions as fractional exponents:

$\dfrac{\sqrt[3]{7}}{\sqrt[5]{7}} = \dfrac{7^{1/3}}{7^{1/5}}$

Recall that $\frac{a^m}{a^n} = a^{m-n}$ , so that

$\dfrac{7^{1/3}}{7^{1/5}} = 7^{1/3 - 1/5}$

Simplify the exponent:

$\dfrac13 - \dfrac15 = \dfrac5{15} - \dfrac3{15} = \dfrac{5-3}{15} = \dfrac2{15}$

Then you end up with

$\dfrac{\sqrt[3]{7}}{\sqrt[5]{7}} = 7^{2/15}$

the first term of an arithmetic sequence is equal to 200 and the common differencence is equal to -10. find the value of the 20t

olga_2 [115]

Answer:

The value for 20th term is 10.

Step-by-step explanation:

First, you have to find the formula for the sequence.

$an = a + d(n - 1)$

$let \: a = 200,d = - 10$

$an = 200 - 10(n - 1)$

$an = 200 - 10n + 10$

$an = - 10n + 210$

Given that the formula of this sequence is an = -10n + 210. Next, you have to find 20th term :

$let \:n = 20$

$20th \: term = - 10(20) + 210$

$20th \: term = - 200 + 210$

$20th \: term = 10$

(Correct me if I am wrong)

Which expression can be used to find the surface area of the following square pyramid

andreyandreev [35.5K]

Answer:

$36+15+15+15+15$

Step-by-step explanation:

For the surface area we need to add up all the areas in the pyramid:

area of the base

area of the triangle sides (there are 4 triangles)

Area of the base:

the base is a square, and the area of a square is given by:

$a_{base}=l^2$

where $l$ is the length of the side: $l=6$ , thus:

$a_{base}=(6)^2\\a_{base}=36$

Area of the triangles:

one triangle has the area given by the formula:

$a_{triangle}=\frac{b*h}{2}$

where $b$ is the base of the triangle: $b=6$

and $h$ is the height of the triangle: $h=5$ , thus we have the following:

$a_{triangle}=\frac{6*5}{2} \\\\a_{triangle}=\frac{30}{2} \\\\a_{triangle}=15$

the expression that represents the surface area of the pyramid is:

$a_{base}+area_{triangle}+area_{triangle}+area_{triangle}+area_{triangle}$

substituting our values:

$36+15+15+15+15$

which is option B
