Answer:

z = 7

Step-by-step explanation:

6z + z - 4z + 4z - 5z = 14

Collect like terms

6 + 1 - 4 + 4 - 5

-4 and 4 cancel out each other so remove it from the equation

6 + 1 - 5 = 2

2z = 14

Divide by 2 to isolate z

z= 7

Find the area of an equilateral triangle with side length 9.2 cm. Round your answer to 1 DP.
lbvjy [14]

Answer:

Area=36.66 cm^2

Step-by-step explanation:

First, you need the height.

Use the Pythagorean theorem:

hypotenuse^2=height^2+(1/2 base)^2  

It's one-half base because it's an equilateral triangle.

1/2 base =4.6

(9.2)^2-4.6^2=height^2

84.64-21.16=height^2

height^2=63.48

height=7.97

Area=(1/2)(base)(height)

Area=(1/2)(9.2)(7.97)=36.66 cm^2

Braxton loves downloading new music he originally had 41 songs but plans to purchase 4 new songs each week. he wants to know how
ycow [4]

Answer:

a_110=41+(110-1)4

Step-by-step explanation:

He already has songs = 41

Since we are given that he purchase four songs every week .

So, in first week he purchase songs = 4

Initially he already has 41 songs

So, total songs after 1 week = 41+(4\times1)=45

After 2 weeks he will have songs = 41+(4\times 2)=49

This forms an arithmetic sequence  : 41,45,49......

Formula of nth term in A.P. : a_n=a+(n-1)d

a = first term = 41

d = common difference = 45-41=49-45=4

Since we are required to find the new songs after110 weeks

So, n =110

Substituting values :

a_110=41+(110-1)4

Thus Option A is correct.
