For each set of three measures determine if they can be angle measures of a triangle
Orlov [11]

Only the second set of measures qualifies as angle measures of a triangle. Angles 25°, 130°, 25°

Step-by-step explanation:

  • Step 1: To find whether angles qualify as angle measures of a triangles, calculate their total sum and verify whether they add up to 180°

Set 1 - 41° + 112° + 52° = 205°

Set 2 - 25° + 130° + 25° = 180°

Set 3 - 30° + 40° + 90° = 160°

Set 4 - 132° + 141° + 31° = 304°

Therefore, only set 2 qualifies.

What is the slope of the line passing through the points (1, –5) and (4, 1)?
xxMikexx [17]
You are given two points that could be plotted on a graph (1,-5) and (4,1). The formula for slope is y2-y1/x2 -x1

When plotted into the points it would look like 1-(-5)/4-1= 6/3

6/3=2. So, the slope for these two points is 2.

3/5 + 1/2 =? ; 1/2 + 3/8 =? ; 1/2 + 2/5=?
slavikrds [6]
3/5+1/2=___
To add them together, convert both fractions so they have the same denominator.
3/5=6/10 and 1/2=5/10
6/10+5/10=11/10, or 1 1/10

1/2+3/8=___
Same for this one- convert both fractions so they have the same denominator.
1/2=4/8 and 3/8 stays the same
4/8+3/8=7/8

1/2+2/5
And again, convert both fractions so they have the same denominator.
1/2=5/10 and 2/5= 4/10
5/10+4/10=9/10

Hope this helps :-)

ratelena [41]

Let's assume

It started in 2000

so, t=0 in 2000

P_0=6.4million

we can use formula

P(t)=P_0 e^{rt}

we can plug value

P(t)=6.4 e^{rt}

In 2005, the same survey was made and the total amount of gamma ray bursts was 7.3 million

so, at t=2005-2000=5

P(t)=7.3 million

we can plug value and then we can solve for r

7.3=6.4 e^{r*5}

r=0.02632

now, we can plug back

P(t)=6.4 e^{0.02632t}

now, we have

P(t)=1 billion =1000 million

so, we can set it and then we can solve for t

1000=6.4 e^{0.02632t}

t=191.924

approximately

t=192

Year is 2000+192

year is 2192................Answer
