Answer:
B.
Step-by-step explanation:
painting a increases expoonentially
1.05(A value)= N
same for painting b by 1.02x
but a increases .3 %more
Speed=distance/time
You'll have to combine like terms.
36+14=50
1.5+0.75=2.25
And then you can use the formula.
50/2.25
Answer:
∡ABC=55°
Step-by-step explanation:
<u>Step 1: Identify all angles</u>
∠A=(x+45)°
∠B=(6x+5)°
∠C=(3x)°
∠ABC=(180-∠B)°=(180-(6x+5))°
<u>Step 2: Use the Triangle Angle Sum Theorem</u>
∠A+∠ABC+∠C=180°
(x+45)+(180-(6x+5))+(3x)=180
x+45+180-6x-5+3x=180
-2x+45+180-5=180
-2x+45-5=0
-2x+40=0
-2x=-40
x=20
<u>Step 3: Plug in x=20 for ∠ABC</u>
∠ABC=(180-(6x+5))°
(180-6(20)-5)°
(180-120-5)°
(60-5)°
55°
So ∡ABC=55°
Answer:

C) 0.51/0.72
D) 0.46/0.293
Step-by-step explanation:
Answer:
Step 1 should have a -2 substituted for both values.
