Complimentary angles add up 90°
let one of the angles be x, the 2nd angle will be (x+4)
thus the total sum will be:
x+(x+4)=90
2x+4=90
thus the right equation is:
<span>B. 2x + 4 = 90</span>
Answer:
25 percent
Step-by-step explanation:
Since the dance team has 9 girls and 3 boys, it is made up of 12 people. 3 of those members are also on the debate team. 12/3 = 4, meaning that a fourth of the dance team is also on the debate team. This translates to 25 percent
Answer:
At most 29 boxes can be safely loaded onto the pallet.
Step-by-step explanation:
Given:
Weight of each box = 55 pound
Weight pallet can support 
1595 pounds.
We need to find the number of boxes .
Solution:
Let the number of boxes loaded safely onto the pallet be 'x'.
So we can say that;
Weight of each box Multiplied by number of boxes should be less than or equal to Weight pallet can support.
framing in equation form we get;
Dividing both side by 55 we get;
Hence At most 29 boxes can be safely loaded onto the pallet.
Answer:
41,6 cm
Step-by-step explanation:
Formula for Perimeter of a rhombus: P = 2L + 2H (H is the height, L the length)
Perimeter: 160 cm = 2L + 2(38,4 cm), or
160 cm + 76.8 cm + 2L, or
83.2 cm = 2L
and so the height (altezza) is H = 83.2 cm / 2 = 41,6 cm
