Calculate the area of this figure to the nearest hundredth. use 3.14 to approximate pi
zaharov [31]

Answer:

49.132 m²

Step-by-step explanation:

Area of a triangle=1/2(base×height)

Area=1/2(6×8)

Area=24 m²

Now

Area of semi circle=πr²/2

Area=(3.14)(8÷2)²/2

Area=(3.14)(4)²/2

Area=(3.14)(16)/2

Area=50.265/2

Area=25.132 m²

Now

Total area=area of triangle+semi-circle

Total area=24+25.132

Total area=49.132 m²

Please help will make brainliest. Write the equation of a line that is parallel to y=9 and that passes through the point (3,-8)
kow [346]

Answer:

y= -8

Step-by-step explanation:

\frac{y- y1}{x- x1}  =  \frac{y + 8}{x - 3}  = m

where m is the slope of the line.

m= 0 which is equal to the slope of the line y=9

because both are parallel.

y + 8 = 0(x - 3)

=  > y =  - 8

Please put answer as a mixed number! :)<br> 1 and 3/8* 1.5 + 5 and 5/8 ÷ 0.4 =
Natasha_Volkova [10]

Answer: 7 1/16  and 1 9/16

Step-by-step explanation:  1 3/8 x 1.5 is 1 3/8 x 1 5/10  11/8 x 15/10 which is 165/80. We divide it by 5/5 to get 33/16. This as a mixed number is 2 1/16.  We add 5 to get 7 1/16.

5/8 divided by 0.4 is 5/8 divided by 2/5. We divide this by first finding the reciprocal of 2/5 which is 5/2. 5/8 x 5/2 = 25/16. This as a mixed number is 1 9/16.

Next number in this series is? 2 2 1/2 1 1/2 2
raketka [301]

First, let's figure out the pattern that this series follows. We can see that the first number is increased by 1/2 to get to 2 1/2. Then, the second number is decreased by 1 to get to 1 1/2. Finally, the pattern repeats.

So, let's apply this pattern to find the next number in this series.

2, 2 1/2, 1 1/2, 2, 1

The next number in this series is 1.

Hope this helps!! :)
