Answer:
t<−4
Step-by-step explanation:
switch sides
-2t-3>5
then add three to both sides:
-2t-3+3>5+3
simplify:
-2t>8
then multiply both sides -1 (reverse the inequality)
(-2t)(-1) <8 (-1\)
simplify:
2t<-8
Divide both sides by 2:
2t/2 <-8/2
Answer: The speed of the river's current is
Step-by-step explanation:
Let's begin by explaining that <u>Speed</u> is a relation between an object's traveled distance in a given time :
So, in this situation the man traveled a distance for a time before realizing he lost his hat.
Keeping this information in mind we can calculate the speed of the river's current, since we already have a reference point: the bridge where the hat fell.
Then:
This is the speed of the river's current
Acute means that has 3 angles less than 90 degrees
obtuse means at lesat 1 angle is more than 90 degrees
right triangle means 1 angle=90 degrees
s we solve for thierd angle
all angles add to 180 so
35+45+x=180
80+x=180
subtract 80
x=100
100>90
obtuse angle is answer

Step-by-step explanation:
<u>Step 1: Define</u>
P(x) = x² + x + 2
P(7) is x = 7
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function]: P(7) = 7² + 7 + 2
- [Output] Exponents: P(7) = 49 + 7 + 2
- [Output] Addition: P(7) = 56 + 2
- [Output] Addition: P(7) = 58
One year has 12 months therefore...
18/12 = 1 6/12 = 1 1/2
1 1/2 is equivalent to 1.5
True
