Answer:
d. $43.00
Step-by-step explanation:
Karli's total cost is ...
total cost = material cost + labor cost
= ($8.00/10 gal)·(5 gal) + ($13.00/h)·(3 h)
= $4.00 + $39.00
= $43.00
For a 30 sided regular polygon, We can divide the polygon (30 sides) into 30 inscribed triangles with central vertex angles of =
.
This central vertex angle of <u>12 degrees</u> is the degree of rotation for a 30 sided polygon.
In other words, the 30 sided polygon has <u>12 degree</u> rotational symmetry about the center.
Answer:
She is not breaking even. The discounted price is .84t, which is less than t.
Step-by-step explanation:
Retail price= 1.4
1.4×.4= .56
40% of 1.4 is .56
Subtract 40% of 1.4 from the retail price because she is marking down.
(1.4)-(.56)=.84
So the discounted price is .84t
This problem is difficult because we don't know if she sold any tea by the retail price and if she did how much did she sell.
Answer:
140,150
Step-by-step explanation:
The sum of the angles in a polygon is
180(n−3)
For a pentagon, this equals 540. Since the first 3 angles add up to 240, the remaining 2 angles must add up to 540−240=300∘
The area of the parallelogram is 26 × 10 = 260 cm^2 ;
The area of equilateral triangle is 0.4 cm^2 ;
<span>The </span>number<span> of triangles can Devi fit on the gris is 260 ÷ 0.4 = 260 × ( 10 / 4 ) = 2600 / 4 = 650 ;</span>
