Find the surface area of the composite figure
solution given:
For Cuboid
length[l]=11mm
breadth [b]=9mm
height[h]=6mm
For semi cylinder
height[H]=11mm
radius[r]=[tex] \frac{9}{2}=4.5mm[/tex]
Now
Totalsurface area=2(lb+bh+lh)+½(2πr(r+H))-l*b[/tex]
:2(11*9+9*6+11*6)+22/7*4.5(4.5+11)-11*9
:438+219.2-99
:558.2mm²
Here area of base is subtracted as it is not included.
Total surface area of composite figure is :558.2mm².

Angle BAC and angle DAE are
complementary. What is the
measure of angle DAE?
Answer:
44 degrees
Step-by-step explanation:
if BAC and DAE are complementary then their sum is equal to 90 degrees
90 - 36 = 44 degrees
Answer:
54
Step-by-step explanation:
your suppose to substract 90 degrees minus 36 = 54
90-36=54

Answer:
$40
Step-by-step explanation:
It's very simple, 0.1 * 150 = 15. Then add $25 by 15. 25 + 15 = 40.
8(39 + 11)
a (8 +39) * (8 + 11) = 893
b. (8 x 39) * (8 x 11) = 27456
C. (8 +39) + (8 + 11) = 66
d. (8 x 39) + (8 x 11) = 400
Answer:
option D is the correct answer

Answer:
measure of angle ABC is 6 degree.
Step-by-step explanation:
After you found x, you'll plug it in the equation of the angle it's asking for.
Measure of angle ABD, and you know measure of angle ABC = 4x-1.
4(1)-1 = 4-1 = 3
Measure of angle CBD = 2x+1.
2(1) +1 = 3
Measure of angle ABC is ABD + CBD
3 + 3 = 6
Answer:
6°
Step-by-step explanation:
We know that is 4x - 1 + 2x + 1
So it equals
6x
or 6 ( 1) = 6°

A cab company charges $4 per cab ride, plus an additional $3 per mile driven. How long is a cab ride that costs $22?
Answer:
6 miles
Step-by-step explanation:
Flat fee is $4
Per mile is $3
Equation :
4 + 3m = 22
subtract 4 from both sides
3m = 18
divide each side by 3
m = 6
The ride is 6 miles.

En un estacionamiento cobran $12.00 la hora y $3.00 por 1/4 de hora ¿Cuánto debo pagar si estacione mi coche a las 11.15am y los saque a las 3.00pm
Ayuda plis doy coronita.
Answer:
$45
Step-by-step explanation:
De 11.00am a 3.00pm hay 4 horas de diferencia.
Eso seria 12x4=$48
Pero necesitamos restarle 1/4 de hora, por lo que se estaciono a las 11.15am y no a las 11.00am
1/4 de hora o 15min= $3.00
48-3=45
