Answer:
The daily cost of hamburger is increasing by $75
Step-by-step explanation:
The fast food restaurant produce a hamburger at $2.50
if the sales are increasing by 30 hamburger per day,
then the daily cost if hamburger is increasing by:
$2.50 × 30 hamburger per day
= $75
Width of the pool: 78 m
explanation: area is length x width, so dividing the area by the length gives you the width
The answer to the above equation is 1.1659 *10⁻¹³
Step-by-step explanation:
We can easily do this equation by knowing some basic indices corollary. These include
- aᵇ=1/a⁻ᵇ similarly a⁻ᵇ = 1/aᵇ
- aᵇ.aⁿ = aᵇ⁺ⁿ
- aᵇ/aⁿ=aᵇ⁻ⁿ
Using these three corollaries we can easily solve the equation-
2.6 x 10⁻⁶/ 2.23 x 10⁷
Using the corollary 1, the equation can be rewritten as-
⇒2.6/2.23 ₓ10⁷ₓ 10⁶
Using corollary 2-
⇒2.6/2.23 ₓ 10⁷⁺⁶
⇒2.6/2.23 ₓ 10¹³
Using corollary 1 in reverse manner (1/aᵇ= a⁻ᵇ)
⇒1.1659ₓ 10⁻¹³
Hence the answer of the equation is 1.1659 ₓ 10⁻¹³
The sum of interior angles of a convex quadrilateral is 360°, so the average angle is 90°. If two of the angles are actually 90°, the remaining two are 90° ± (10°)/2, so are 85° and 95°.
The angles are 90°, 90°, 95°, 85°.
