Answer:
the number of deliveries would be 13
And, the equation is d ≥ 12.50
Step-by-step explanation:
The inequality function is given below:
Let us assume the d be the number of deliveries
10 × 8 + 6 × d ≥ 155
80 + 6d ≥ 155
6d ≥ 155 - 80
6d ≥ 75
d ≥ 75 ÷ 6
d ≥ 12.50
hence, the number of deliveries would be 13
And, the equation is d ≥ 12.50
<h3>Given:</h3>
<h3>Note that:</h3>
- Hyp= Hypotenuse
- Adj= Adjacent
<h3>To find:</h3>
The size of the unknown angle "x".
<h3>Solution:</h3>
We'll have to check which one is appropriate from SOHCAHTOA.
In this question we'll have to use cos because hypotenuse and adjacent is given.

Substitute according to the formula.

We'll have to use cos inverse.

Cuz 11 - 7 = 4
Answer:
last year 8 boys 12 girls and this year 10 boys 15 girls
Step-by-step explanation:
ratio = 4:6
total ratio = 6 +4 =10
last year
ratio 1 = 20 ÷ 10 = 2
boys = 2 × 4 = 8
girl = 2 × 6 = 12
this year
ratio 1 = 25 ÷ 10 = 2.5
boys = 2.5 × 4= 10
girls = 2.5 × 6 = 15
