Let a<b<c
c=75+a and (a+c)/3=b
using c from the first in the second you have:
b=(a+75+a)/3
b=(2a+75)/3
Since this is a triangle, a+b+c=180, using b and c from above we get:
a+(2a+75)/3+75+a=180 making the left side have a common denominator 3
(3a+2a+75+225+3a)/3=180 combine like terms on left side
(8a+300)/3=180 multiply both sides by 3
8a+300=540 subtract 300 from both sides
8a=240 divide both sides by 8
a=30°, since b=(2a+75)/3
b=45°, since c=75+a
c=105°
So the angles are 30°, 45°, and 105°
Answer:
The regular price for 1 pound of flour was $ 1.29
Step-by-step explanation:
Price Percentage
$ 16.24 90
x 100
***************************
90 * x = 16.24 * 100
90x = 1,624
x = 1,624/90
x = 18.05
Now, let's calculate the price of each bag of flour, this way:
Price of each bag = 18.05/7
Price of each bag = $ 2.58 (rounding to the next cent)
Finally, we can calculate the regular price for 1 pound of flour:
Regular price for 1 pound of flour = 2.58/2
Regular price for 1 pound of flour = $ 1.29
It’s very likely that she would pick a colored shirt. The percent would be 5%
Answer: it is 29
its less than 30 becuse u would substutut x for 30 so
4x30= 120
+
30+6=36
+
30
=
186 but u need 180
29
4x29= 116
+
29+6=35
+
29
=
180
This is the concept of linear proportionality, the linear scale factor of the polygon given will be:
[perimeter of larger polygon]/[perimeter of smaller polygon]=[length of larger polygon]/[length of smaller polygon]
=28/20
=7/5
thus the length of the larger polygon will be given by:
7/5=x/4
thus;
7/5*4
=5.6
thus the length 5.6
