Since it is a Trapezoid:

TR is Parallel to PA

For a Parallel lines the sum of the 2 opposite interior angles add up to 180

Therefore:

x + (3x + 16) = 180

x + 3x + 16 = 180

4x + 16 = 180

4x = 180 - 16

4x = 164

x = 164/4

x = 41

x = 41 degrees. Option C.

What is the ratio of a : b, knowing that a — b = 3 <br> a + b = 5

UNO [17]

Answer:

4:1

Step-by-step explanation:

a — b = 3

then a= 3+b

a + b = 5

3+b +b = 5

3+2b=5

2b=5-3

2b=2

b=1

a= 3+b

a=3+1=4

a:b= 4:1

Paraplatin 360mg/m2 in 150ml normal saline via ice pump. Drug run over 30 minutes. At what rate should the nurse at IV pump

olasank [31]

<span>Drag concentration( 360mg) per body surface (m2) is irrelevant to the infusion rate, which is volume divided by time, i.e. 150/(30/60) = 300ml/h</span>

A lot is 21 ft by 30 ft. To support a fence, an architect wants an upright post at each corner and an upright post every 3 ft in

Bogdan [553]

What we know:
Lot= 21 x 30ft
Perimeter=2l+2w
Want to put 4 corner post and one post every 3 ft

What we need to find:
How many post we need.

Perimeter=2 (21)+2 (30)=42+60=102ft

102/3=34

34 posts are needed.

Do you mean xy instead of sy if so i’m pretty sure you would just multiply both of the numbers

Identify the sequence as arithmetic, geometric, or neither. Explain your answer.

mestny [16]

This sequence (1.6, 0.8, 0.4, 0.2,... ) is geometric.
We have formula for any member of geometric sequence: $a_{n} = a_{1}* q^{n-1}$ If a1=1.6 then: $0.8=1.6*q, 0.4=1.6* q^{2}, 0.2=1.6* q^{3}$ The solution for all these equations is: q=0.5. We have: a1=1.6, q=0.5 and this is geometric sequence.
