Diameter of small pizza = diameter of large pizza divided by 2 = 9 inches
x = y divided by 2
x = 9 inches
Answer:
c = 5
Step-by-step explanation:
This is the classic problem that the ancients (particularly the Egyptians) used extensively. When the Nile over flowed in spring, the land had to be reclaimed and surveyed in the early summer for planting. The 3-4-5 triangle was used to determine right angles for surveying purposes.
Formula
c^2 = a^2 + b^2
Givens
a = 3
b = 4
c = ?
Solution
c^2 = 3*3 + 4*4
c^2 = 9 + 16
c^2 = 25
Take the square root of both sides
To take the square root on your calculator, find the √ on the key pad. Some calculators give it a key and some have the symbol on the body of the calculator. If has its own key do it like this.
√
25
=
The answer should come up as five. If the √ is on the body of the calculator, then
2nd F
√
25
=
The same 5 will come up.
Answer
c = 5
Answer:
The answer is= 119 Bushels and a half(119.5)
Step-by-step explanation:
Equation related to the problem= 220-(67/4)·T=bushels of Beans left
After 6 days=
220-(67/4·)6=bushels of Beans left
Bushels of beans left=119.5---> You need to change the dot for a fraction
119.5 is 119 bushes and a half so
The answer is= 119 Bushels and a half(119.5)
The picture in the attached figure
let
x--------> perimeter of triangle CED
y--------> perimeter of triangle BEA
we know that
∠A=∠D
∠B=∠C
∠E is equal in both triangles by vertical angle
so
triangle CED and triangle BEA are similar
x+y=110------> x=110-y------> equation 1
x/y=3/2----> 2x=3y-----> equation 2
substitute equation 1 in equation 2
2*[110-y]=3y-----> 220-2y=3y----> 3y+2y=220---> 5y=220----> y=44 units
x=110-y-----> x=110-44-----> x=66 units
the answer isperimeter of triangle CED is 66 unitsperimeter of triangle BEA is 44 units
Well in the bottom one x =1 and y=2
