The Traingle XYZ and ACB are similar triangles. tanX = tanA = 5 over 2 and 5 tenths,
AC = 2 * XY; CB = 2 * YZ
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Triangle XYZ was dilated by a scale factor of 2 to create triangle ACB, hence XYZ and ACB are similar triangles.
Angles Y and C both measure 90 degrees, and angles A and X are congruent. Hence:
tanX = tanA = 5 over 2 and 5 tenths
AC = 2 * XY; CB = 2 * YZ

0.5 of a mile - since 5,280ft = 1 mile and half of 5,280 is 2,640
Answer:
d) 0.798
Step-by-step explanation:
Since we know that an exponential function is in form: 
, where,
a= Initial value,
b = For growth b is in form (1+r), where r is rate in decimal form.
b = For decay or regression b is less than 1 and in form (1-r), where r is rate in decimal form.
Upon looking at our given choices we can see that options a, b and c are in form 1+r, while choice provided in option d is less than 1 and in form 1-r, therefore, option d is the correct choice.
Answer:
$3.78
Step-by-step explanation:
find 107%(100%=$54+7%=107%)
54*107/100= $57.78
find the amount of sale tax
57.78-54=$3.78
