First let as solve all unit pirce
whistles 21.25 / 25 = $ 0.85 per unit
36 / 50 = $ 0.72 per unit
60 / 80 = $ 0.75 per unit
kazoos
10 / 25 = $ 0.4 per unit
18.50 / 50 = $ 0.37 per unit
27.20 / 80 = $ 0.34 per unit
a.) $ 0.85 - $ 0.72 = $ 0.13
b.) 10 / 25 = $ 0.4 per unit
c.) he must order 80 kazoos she should

The measure of each angles are m∠F = 46°, m∠D = 32°, m∠E = 102°.
<h3>What is angle?</h3>
An angle in plane geometry is a shape created by two rays or lines that have a common endpoint. The Latin word "angulus," which means "corner," is where the word "angle" comes from. The common endpoint of two rays is known as the vertex, and the two rays are known as sides of an angle.
The angle that lies in the plane need not be in Euclidean space. Angles are referred to as dihedral angles if they are produced by the intersection of two planes in a space other than Euclidean. The symbol "" is used to represent an angle.
We have given that Δ DEF has
m∠D = m∠F - 14
And
m∠E = 10 + 2(m∠F)
We know that that sum of all angels in a triangle is 180°, So
m∠D + m∠E + m∠F = 180°
Substituting the values we get
(m∠F - 14) + (10 + 2(m∠F)) + m∠F = 180°
m∠F - 14 + 10 + 2m∠F +m∠F
4(m∠F) - 4 = 180
4(m∠F) = 180 + 4
4(m∠F) = 184
(m∠F) = 46°
m∠D = 46° - 14
m∠D = 32°
m∠E = 10 + 2(m∠F)
m∠E = 10 + 2( 46°)
m∠E = 10 + 92°
m∠E = 102°

Answer:
![\frac{337878up*ua}{5252up}=64.33ua\\\frac{113434up*ua}{5252up}=21.59ua](https://tex.z-dn.net/?f=%5Cfrac%7B337878up%2Aua%7D%7B5252up%7D%3D64.33ua%5C%5C%5Cfrac%7B113434up%2Aua%7D%7B5252up%7D%3D21.59ua)
Step-by-step explanation:
If the ratio between the plan and the measure is 5252: 1, this means that each unit of the plan (up) is equivalent to 5252(ua) units of measure actually
, also:

Answer:
![x=\frac{3}{5}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B3%7D%7B5%7D)
Step-by-step explanation:
Midpoint of a line is a point that divides it into two equal segments.
As B is the midpoint of line segment AC,
![AB=BC](https://tex.z-dn.net/?f=AB%3DBC)
Put ![BA=8x+9\,,\,CA=28x-3](https://tex.z-dn.net/?f=BA%3D8x%2B9%5C%2C%2C%5C%2CCA%3D28x-3)
To find value of
, solve ![8x+9=28x-3](https://tex.z-dn.net/?f=8x%2B9%3D28x-3)
Therefore,
![8x+9=28x-3\\9+3=28x-8x\\12=20x\\x=\frac{12}{20}\\ x=\frac{3}{5}](https://tex.z-dn.net/?f=8x%2B9%3D28x-3%5C%5C9%2B3%3D28x-8x%5C%5C12%3D20x%5C%5Cx%3D%5Cfrac%7B12%7D%7B20%7D%5C%5C%20x%3D%5Cfrac%7B3%7D%7B5%7D)
So, value of
is ![\frac{3}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D)
