Area of rectangle = Length x width, Area of triangle - (1/2) base x height
Surface Area is the sum of the area of all of the faces.

Your picture has 5 faces:
1) rectangle on the left
2) square in the middle
3) rectangle on the right
4 & 5) 2 congruent (identical) right triangles

Area of face #1: 5 x 4 = 20
Area of face #2: 4 x 4 = 16
Area of face #3: 3 x 4 = 12
Area of face #4: (1/2) x 3 x 4 = 6
Area of face #5: (1/2) x 3 x 4 = 6
Sum of the Area of the faces: 60

Answer: Surface Area of the figure is 60 units²

Volume = Length x width x height
= 5 x 4 x 3
= 60 units³

Answer: Volume of the figure is 60 units³

Surface area is not the volume

Surface area=60units^2

2 triangles(4x3)/2 = 6 units each=12 units

1 square 4x4=16units

1 rectangle 4x3=12

1 rectangle 4x5=20

6+6+16+12+20=60 units^2

If a man runs for an hour and a half at 8 miles an hour due south; and then he continues south on a bus traveling at 55 miles an

Usimov [2.4K]

He ran 8 miles per hour.

Multiply his speed by the time he ran to find total distance:

8 mph x 1.5 hours = 12 miles

He ran for 12 miles.

Now Find the distance the bus went:

For time, divide the minutes the bus drove by 60 minutes per hour.

55 miles per hour x 24/60 = 22 miles

The bus went 22 miles.

Total distance = 12 + 22 = 34 miles.

Evaluate the expression for x = 8, y = 4: x + 10/y+5

Nesterboy [21]

Answer:

Solution,

X=8

y=4

Now,

 $\frac{x + 10}{y + 5} \\ = \frac{8 + 10}{4 + 5} \\ = \frac{18}{9} \\ = 2$ 

hope this helps...

Good luck on your assignment..

In a triangle, one angle measures 68° and another

pshichka [43]

Answer:

74°

Step-by-step explanation:

all angles of a triangle will always end up equal to 180°

68 + 38 = 106

180 - 106 = 74

In each of the following data sets, tell whether the outlier seems certain to be due to an error or whether it could conceivably

emmasim [6.3K]

Answer:

a) There is outlier (lower category), but this outlier seem certain to be due to an error.

b) There is outlier (upper category), this outlier seem certain to be conceivably correct.

Step-by-step explanation:

a) The outlier in the rock weight is certain to be due to an error. As shown, the rock was weighed five time to ascertain the actual weight or perhaps to known the mean weight. Thus, having a value 4.91 can not be true. It can only be due to an error of recording the values. It suppose to be recorded as 49.1.

b) Since this was a sample of annual income of five different families, it quite possible that a particular family annual income is $1, 200, 000. Hence, we cannot regard this outlier an error, rather conceivably true.

See attached for the box plot of the two data sets.
