- b^{4} + 6b^{3}

divide each term on the numerator by 7b

= - 7b^{5} / 7b + 42b^{4} / 7b

= - b^{4} + 6b^{3}

A ribbon is 12 3/8.Into how many 3/4 peices can it be cut?
lozanna [386]

namely how many times does 3/4 go into 12⅜?

let's firstly convert the mixed fraction to improper fraction, and then divide.


\bf \stackrel{mixed}{12\frac{3}{8}}\implies \cfrac{12\cdot 8+3}{8}\stackrel{improper}{\cfrac{99}{8}} \\\\\\ \cfrac{99}{8}\div \cfrac{3}{4}\implies \cfrac{99}{8}\cdot \cfrac{4}{3}\implies \cfrac{99}{3}\cdot \cfrac{4}{8}\implies 33\cdot \cfrac{1}{2}\implies \cfrac{33}{2}\implies 16\frac{1}{2}

What number should be added to 7/12 to get 4/15?​
DENIUS [597]

Answer:

Step-by-step explanation:

Let the number = x.

We are trying to find out what number (x) we would need to add to 7/12 to get 4/15

\frac{7}{12}  + x = \frac{4}{15}

Subtract 7/12 from both sides.

x = \frac{4}{15}  - \frac{7}{12}

We need to make the denominators of the fractions the same.

\frac{4}{15}  = \frac{16}{60}

\frac{7}{12}  = \frac{35}{60}

So,

x = \frac{16}{60}  - \frac{35}{60}  = -  \frac{19}{60}

Two cities have nearly the same​ north-south line of 110 degrees Upper W. The latitude of the first city is 23 degrees Upper F c
inn [45]

Answer:

CORRECTED QUESTION:

Two cities have nearly the same​ north-south line of 110 degrees Upper W. The latitude of the first city is 23 degrees Upper N, and the latitude of the second city is 36 degrees N. Approximate the distance between the cities if the average radius of Earth is 6400 km.

ANSWER: 1452.11 km

Step-by-step explanation:

Since the two cities both lies on the Northern latitude of the sphere along  the same longitude, we are going to subtract the angles the latitude that each city subtend at the equator.

36 - 23 = 13 degrees   i.e the angles between the with two cities on a cross section the large circle formed by the longitude and its center.

Applying   the formula for the length of an arc on a sector on the large circle  

(∅/ 360) x 2πR

where, ∅ = is the angle between the two cities

R = radius of the Earth.

13/360 x 2 x π x 6400 = 1452.11 km

Vlada [557]
If the goal is to sell at least $1500 worth of tickets then what you can do is add the 12.50+ 6.25 which well equal 18.75. Then you can divide 1500/18.75 which eqauls to 80 meaning at least 80 seats must be sold
