A delivery person uses a service elevator to bring boxes of books up to an office. The delivery person weighs 170lb and each box of books weighs 60 lb. The maximum capacity of the elevator is 1240lb. How many boxes of books can the delivery person bring up at one time?
Answer:
17.83 boxes
Step-by-step explanation:
Lets represent the number of boxes of books that can be brought up per time = x
From the question: The delivery person weighs 170lb and each box of books weighs 60 lb. The maximum capacity of the elevator is 1240lb.
Hence we have the Algebraic Expressions
170lb + 60 × x = 1240lb
170lb + 60x = 1240lb
Collect like terms
60x = 1240lb - 170lb
60x = 1070lb
x = 1070lb/60
x = 17.833333333
x = 17.83 boxes
Therefore, the delivery person can bring up 17.83 boxes per time

A hospital stores one type of medicine in 2-decagram
containers. Based on the information given in the
box above, how many l-milligram doses are there in
one 2-decagram container?
A) 0.002
B) 200
C) 2,000
D) 20,000
Answer:
There are 20,000 milligrams in one 2-decagram container . Thus option D is correct.
Step-by-step explanation:
The given information is one type of medicine in 2 decagram container.
Here, we know ,
1 decagram = 10 grams
and, 1000 milligrams =1 gram
now -: 2 decagram = 2 × 10grams {since 1decagarm = 10 grams }
= 20 grams .
then , = 20× 1000milligrams {since 1 gram = 1000 milligrams}
=20,000 milligrams .
Hence, the correct option is D that is 20,000 milligrams .
0.4 = -9.8 -y + 2.8y
Answer: [tex]y=5.666667[/tex] or [tex]y=5 \frac{6}{9}[/tex] in fraction
Step-by-step explanation:
1. Simplify -9.8-y+2.8y to -9.8+1.8y
0.4=-9.8+1.8y0.4=−9.8+1.8y
2. Regroup terms
0.4=1.8y-9.8
3. Add 9.8 to both sides.
0.4+9.8=1.8y
4. Simplify 0.4+9.8 to 10.2
10.2=1.8y
5. Divide both sides by 1.8
[tex]\frac{10.2}{1.8} =y\\[/tex]
6. Simplify [tex]\frac{10.2}{1.8\\}[/tex] to 5.666667
5.666667 = [tex]y[/tex]
7. Switch sides.
[tex]y=5.666667[/tex]

SOLVE QUESTION 3 PART A AND B !! WILL GIVE BRAINLIST ..
Answer:
28π, reasonable
Step-by-step explanation:
A. Circumference is 2πr (or dπ), so we plug in 14 for r
this leaves us with 2π14, in which the 2 and 14 can multiply, so we get 28π
B. if we plug 28π into the calculator, you'll get 87.96, so 85cm is reasonable

According to the graphic method, the quintic function has a real root at (x, y) = (- 3, 0) and four complex roots.
How to find the roots of quintic equation
Quintic functions are polynomics of degree 5, there are numerical and graphical approaches to find real roots of those kind of polynomials. By algebra we know that quintic equations have at a least one real root and at most five real roots.
In this problem we shall use a graphic approach to determine the real roots of the quintic equation, as it offers sufficiency and quickness for analysis. Please notice that a point of the curve is a root if the point lies on the x-axis.
The graph is contained in the image attached below. According to the outcome, the quintic function has a real root at (x, y) = (- 3, 0) and four complex roots.

solve for r step by step v =1/3 IIR^3 h
Answer:
[tex]r=\sqrt[3]{\frac{3v}{\pi h} }[/tex]
Step-by-step explanation:
The equation is v=1/3πr³h
Multiply both sides of equation by 3 to get
3v=πr³h
Divide both sides of the equation by πh to get
3v/πh = r³
Apply cube root on both sides of the equation as;
[tex]\sqrt[3]{\frac{3v}{pih} } =r[/tex]
