Add- 

0.859+1.63=2.489

Subtract- (Not sure where the decimal was)

0.859-0.03=0.829

0.859-00.3=559

Multiply-

0.859*10^1=8.59

0.859*10^2=85.9

0.859*10^3=859

0.859*10^4=8590

Divide-

0.859/10^1=0.0859

0.859/10^2=0.00859

0.859/10^3=0.000859

0.859/10^4=0.0000859

Round-

An executive drove home at an average speed of 30 mph to an airport where a helicopter was waiting. The executive boarded the he

wlad13 [49]

Answer:

120 miles

Step-by-step explanation:

Formulate equations.

Distance = rate * time.

D1 = distance from home to airport

D2 = distance from airport to off

D1 + D2 = 150

30 x t1 + 60 x t2 = 150

Divide through by 30

t1 + 2t2 = 5 ----- equation 1

Entire trip took 3 hours

t1 + t2 = 3 -------------------- equation 2

Solve equation 1 and 2 and you get

t1 = 1 hour

t2 = 2 hour

D2 = t2 x speed = 2 x 60

= 120 miles.

You use Pythagorean theorem to solve this problem.a^2+b^2=c^2
A.53*53=45*45+28*28
2809=2025+784
2809=2809

B.85*85=13*13+84*84
7725=169+7056
7725=7725
C.85*85=36*36+77*77
7725=1296+5929
7725=7725
D.65*65=16*16+61*61
4225=256+3721
4225=3977

The answer is D

The surface area of a rectangular prism is 2210 cm2. Two of the dimensions are 5 cm and 10 cm. Find the measure of the other dim

Vlad [161]

The surface area of a rectangular prism is 2210 cm^2 Then the other dimension is 70.3 cm

<h3>Solution:</h3>

Given that surface area of rectangular prism is 2210 square centimeter

Also given that two of dimensions are 5 cm and 10 cm

To find: other dimension

The total surface area of the rectangular prism is gievn as:

$\text {Total surface area }=2(lb+b h+h l)$

Where, "l" is the length and "b" is the breadth and "h" is the height

The given values are: l = 5cm and b = 10cm

On substituting the given values in formula we get,

$\begin{array}{l}{2210=2(l \times b+b \times h+h \times l)} \\\\ {2210=2(5 \times 10+10 \times h+h \times 5)} \\\\ {2210=2(50+10 h+5 h)} \\\\ {1105=50+15 h} \\\\ {1055=15 h} \\\\ {h=70.3}\end{array}$

Thus the other dimension is 70.3 cm
