On a shopping trip, Peter spent 1/3 of his money for a jacket and another $5 for a hat. If peter still had 1/2 of his money left

katen-ka-za [31]

Let x be the money he had originally.
x/3+5=x/2
5=x/6
x=30
So he had $30 originally.

Please help!!!!!!!!!!

Find the length of AB
AB²=20²+15²
AB²=400+225
AB²=625
AB=25

then find AD and BD
20²=AD·25
400=AD·25
AD=16
15²=BD·25
225=BD·25
BD=9
now use the geometric mean theorem (name?) to find CD
CD=√(9·16)
CD=√144
CD=12 cm

The length of a rectangle is 5 times as long as the width. If the perimeter is 60 meters, find the length and the width.

Dennis_Churaev [7]

hi <3

lets call our width 'x' and our length '5x'

so lets create an equation with what we know:

5x + 5x + x + x = 60

simplify:

12x = 60

divide both sides by 12:

x = 5

5(5) = 25

therefore, the width is 5m and the length is 25m

hope this helps :)

A store is designing the space for rows of nested shopping carts. Each row has a starting cart that is 4 feet long, followed by

Mariulka [41]

Answer:

The graph is plotted below.

Step-by-step explanation:

Given:

Starting cart means number of nested carts is 0.

So, let the number of nested carts be represented along the x axis and height of the nested carts be represented along the y axis.

As per question,

When $x=0$ , the height is $y=4\ ft$

When $x=13$ , the height is $y=23.5\ ft$

When $x=18$ , the height is $y=31\ ft$

So, the points on the graph are (0,4), (13, 23.5) and (18, 31).

Plot these points on a graph and draw a line passing through all these points starting at (0, 4) and ending at (18, 31).

The graph is shown below.

For f(x) = 2x +1 and g(x) = x^2-7, find (f/g) (x)

Rashid [163]

the answer is (f/g)(x) = 2(x^2 - 7) + 1
= 2x^2 - 14 + 1
= 2x^2 - 13
