Answer:
Lisa's percentage of error regarding the weight of the dog was 57.14%.
Step-by-step explanation:
Given that the German Shepard actually weighs 28 pounds, but Lisa thought the dog weighed 44 pounds, to determine what is the percent error the following calculation must be performed:
28 = 100
44 = X
(44 x 100) / 28 = X
4,400 / 28 = X
157.14 = X
157.14 - 100 = 57.14
Thus, Lisa's percentage of error regarding the weight of the dog was 57.14%.
Answer:
B)313 ft
Step-by-step explanation:
Hello,I think I can help you with this
to solve this you need to find all the measures of the rigth triangle formed by Hailey, the boat, and the point on the surface of the sea just above the head of Hailey
Step 1
define
triangle
Hypotenuse=300 feet
opposite side=y
adjacent side=x
angle of depression =30°
Step 2
find the distances
so, the point on the surface of the sea just above hailey is 259.8076 ft from the boat
hailey is at a depth of 150 feet
Step 3
now,her partner is 25 feet directly below her,it is
partner's depth is =hailey is at a depth of 150 feet+25
Y=175
he is at the same distance from de boat ( horizontal),because it is the same point in the sea surface.
X=259.80
Step 4
to find the distance between the partner and the boat we can use
Pythagoras theorem
![adjacentside^{2} +opposite side^{2} =hypotenuse^{2} \\\sqrt[2]{adjacentside^{2} +opposite side^{2}} =Hypotenuse\\Hypotenuse=\sqrt[2]{175^{2} +259.8076^{2}} \\\\Hypotenuse=313.24 ft](https://tex.z-dn.net/?f=adjacentside%5E%7B2%7D%20%2Bopposite%20side%5E%7B2%7D%20%3Dhypotenuse%5E%7B2%7D%20%5C%5C%5Csqrt%5B2%5D%7Badjacentside%5E%7B2%7D%20%2Bopposite%20side%5E%7B2%7D%7D%20%3DHypotenuse%5C%5CHypotenuse%3D%5Csqrt%5B2%5D%7B175%5E%7B2%7D%20%2B259.8076%5E%7B2%7D%7D%20%5C%5C%5C%5CHypotenuse%3D313.24%20ft)
so, Hailey's diving partner is 313 ft away from the boat(B)
Have a great day.
33%=0.33
33% of 39=0.33*39=12.87
discount is 12.87
minus
39-12.87=26.13
sale price=$26.13
discount=$12.87
Rounding decimals is very similar to rounding other numbers. If the thousandths place of a decimal is four or less, it is dropped and the hundredths place does not change. For example, rounding 0.843 to the nearest hundredth would give 0.84.
If the thousandths place is five through nine, the hundredths place is increased by one. The decimal 0.846 rounded to the nearest hundredth is 0.85.
29/337 is not a decimal and I'm not sure why you are dividing it. Please specify. :-)
Answer:
Probably because learning to do polynomials by hand boosts understanding of the topic and improves general algebraic solving ability,both of which are required in further topics like advanced calculus and algebra
