What is the difference between adding and subtracting fractions and multiplying and dividing fractions?

1 answer:

4 0

With adding and subtracting fractions, you must find a common denominator. In multiplication, you just multiply numerator by numerator; denominator by denominator. In division, you multiply the fraction by the reciprocal of the 2nd. In multiplication and division, finding a common denominator is not needed.

If 1st and 4tg terms of G.p are 500 and 32 respectively it's second term is ?

bixtya [17]

Answer:

$T_{2} = 200$

Step-by-step explanation:

Given

Geometry Progression

$T_1 = 500$

$T_4 = 32$

Required

Calculate the second term

First, we need to write out the formula to calculate the nth term of a GP

$T_n = ar^{n-1}$

For first term: Tn = 500 and n = 1

$500 = ar^{1-1}$

$500 = ar^{0}$

$500 = a$

$a = 500$

For fought term: Tn = 32 and n = 4

$32 = ar^{4-1}$

$32 = ar^3$

Substitute 500 for a

$32 = 500 * r^3$

Make r^3 the subject

$r^3 = \frac{32}{500}$

$r^3 = 0.064$

Take cube roots

$\sqrt[3]{r^3} = \sqrt[3]{0.064}$

$r = \sqrt[3]{0.064}$

$r = 0.4$

Using: $T_n = ar^{n-1}$

$n = 2$ $r = 0.4$ and $a = 500$

$T_{2} = 500 * 0.4^{2-1}$

$T_{2} = 500 * 0.4^1$

$T_{2} = 500 * 0.4$

$T_{2} = 200$

Hence, the second term is 200

Please help me out!! :D

Rudik [331]

$T_n = a_1 + d(n - 1)
$

$T_n = 52 + 12(n - 1)$

$T_n = 52 + 12n - 12$

$T_n = 40 + 12n$

When n = 102,
$T_{102} = 40 + 12(102) = 1264$

Answer: 1264

4. When finding the intersection of two lines from both Algebra I and Geometry, you first "set the linear

Masteriza [31]

Answer:

The intersection point is (-4,-19)

Explanation:

The two given equations are:

y = 5x + 1

y = 2x - 11

To find the intersection point, we will start by equating the two given equations and solving for x

This is done as follows:

5x + 1 = 2x - 11

5x - 2x = -11 - 1

3x = - 12

x = -4

Then, we will use the x and substitute in any of the equations to get the value of y

Using the first equation:

y = 5x + 1 = 5(-4) + 1 = -19

Check using the second equation:

y = 2x - 11 = 2(-4) - 11 = -19 ................? checked

Therefore:

The intersection point between the two given equations is (-4,-19)

Hope this helps :)

A baseball player got 52 hits one season. He got h of the hits in one game. What expression represents the number of hits he got

Mars2501 [29]

Answer:

The expression that represents the number of hits he got in the rest of the games is $t=52-h$ .

Step-by-step explanation:

Given:

Number of hits in one season = 52 hits

Number of hits in one game = 'h'

We need to write expression that represents the number of hits he got in the rest of the games.

Solution:

Let the number of hits he got in the rest of the games be 't'.

Now we can say that;

The number of hits he got in the rest of the games is equal to Number of hits in one season minus Number of hits in one game.

framing in equation form we get;

$t=52-h$

Hence expression that represents the number of hits he got in the rest of the games is $t=52-h$ .
