X=8 she needs 120, she has 45. She needs 75 more. $10 an hour x 8 = $80
Answer:
1. 60 degrees
2. 50 degrees
4. 49 degrees
5. 26 degrees
Step-by-step explanation:
The sum of the measures of the angles of a triangle is 180 degrees.
1.
x + 80 + 40 = 180
x + 120 = 180
x = 60
2.
x + 75 + 55 = 180
x + 130 = 180
x = 50
4.
x + 90 + 41 = 180
x + 131 = 180
x = 49
5.
x + 81 + 73 = 180
x + 154 = 180
x = 26
Answer:
20°
Step-by-step explanation:
ΔCAD
BD=CD
∠BCD=50°, ∠BAD= 30°, x= ?
------------
BD=CD ⇒ ∠CBD= ∠BCD= 50° ⇒ ∠BDC= 180°- 50°×2= 80°
∠ADC= 180° - (50°+30°)= 100°
x= ∠ADC - ∠BDC= 100° - 80°= 20°
x= 20°
Hey there! I'm happy to help!
To find the volume of a cylinder, you multiply the base by the height.
First, we find the base. The base is a circle. To find the area of a circle, you square the radius and multiply it by pi (we will use 3.14). The radius is half the diameter.
6.5/2=3.25
We square this.
3.25²=10.5625
And multiply by 3.14
10.5625(3.14)=33.16625
Now we multiply this by the height.
33.16625(12)=397.995
Therefore, the volume of this silo is 397.995 cubic meters.
Have a wonderful day! :D
