Answer:

138 cm^2 = Area . 54 cm = Perimeter

Step-by-step explanation:

Find the area of the triangle- b * h = A

8 * 6 = A

48/2 = A

24 = A

Find the area of rectangle- l * w = A

16 * 7 = A

112 = A

Add the areas together. 24 + 112 = 136 cm^2

Perimeter is adding up all the sides. s + s + s + s + s

16 + 7 + 8 + 10 + 13 = 54 cm

Answer:

perimeter of this figure is = 54 cm

and area of traingle is = 1/2*base *height

so = 1/2*8*6

=. 24cm*cm

and area of rectangle = length * breadth 

 area = 112cm*cm

so total area = 112+ 24 = 136cm*cm 

hope it helps and your day will full of happiness

A race car moving along a circular track has a centripetal acceleration of 15.4^2. If the car has a tangential speed of 30 what

Dominik [7]

In uniform circular motion (circular motion at same speed), (tangential velocity)^2/radius = acceleration towards the center of the circle (centripetal acceleration)
Also, radius is the distance to the center of the circle (track). 
So, in your case, 15.4m/s^2 = (30.0m/s)^2/(radius) 
radius = (900.m^2/s^2) / (15.4m/s^2) 
radius = 58.4m

–3(5y – 4) ≥ 17 Solve and graph on a number line thanks

likoan [24]

Answer:

$y\leq 1.93$

Step-by-step explanation:

To know the value that y takes according to the inequation $-3(5y-4)\geq 17$ , we must do some algebra.
First of all, we divide both terms by (-3), wich would change the direction of the inequality, as follow: $(5y-4)\leq\frac{17}{(-3)}$ (at this point you should remember that dividing or multiplying an inequation by anegative number changes the direction of the inequality)..
This means that $(5y-4)\leq 5.67$ . Then,we just have to add both sides 4, which yields $5y\leq 5.67+4$ .
Then $5y\leq 9.67$ , which means that, if we divide both sides by 5, we obtain the value of y: $y\leq 1.93$ (in this case, the direction of inequality does not change because 5 is possitive).
