The perimeter is 10.3.  I think that's already in significant digits, but I'm not sure.  We just got finished learning that in chemistry and it confused me to death!

Answer: The perimeter of this triangle is 10.30 inches

Solution:

The sides of a triangle measure 2.24 inches, 3.56 inches, and 4.50 inches:

a=2.24 inches

b=3.56 inches

c=4.50 inches

What is the perimeter of this triangle?

Perimeter of the triangle: P=?

The perimeter of a polygon is the sum of the measurements of the sides. In the case of a triangle (three sides) with side a, b, and c:

P=a+b+c

Replacing the given values:

P=2.24 inches+3.56 inches+4.50 inches

P=10.30 inches

Lola dice Argos mi perro tiene 10 kg menos que roco cuantos kilogramos tiene argos
Elena L [17]

Answer:

A=R-10

Step-by-step explanation:

The problem is:

<em>Lola says: Argos, my dog, has 10 kilograms less than Roco. How much kilograms Argos has?</em>

<em />

This problem is about algebraic language. We just need to express the ordinaty language into an equation.

We know the words less means difference. So, let's call A Argos' weight and R Roco's weight. We can expresse the given problem as

A=R-10

Notice that we applied a difference due to the word "less" in the problem.

Therefore, Argo's weight is given by the expression

A=R-10

1990 population was 254 million in 2014 it was 303 what was the percentage increase in the population
Ann [662]

Answer:

19.29%

Step-by-step explanation:

Given

Population in 1990

= 254000000

Population in 2014

= 303000000

Increase = 303000000 - 254000000

= 49000000

% increase in population =

Increase /initial population x 100%

That’s

49000000/254000000 x 100%

0.1929 x 100%

19.29%

The population increased by 19.29%

Researchers wanted to see which species of lizard (A, B, or C) is most likely to survive a bacterial infection. So they infected
Slav-nsk [51]

Answer:

A) attached below

B) 0.61

C) 0.47

Step-by-step explanation:

Given data:

Total number of lizards infected = 38

Of the 15 species B lizards 40% survived

For specie C one more survived than died

Out of the 24 lizards that died 1/3 were species A

<u>A) contingency table </u>

attached below

<u>B) Determine the proportion of these lizards in this study that were either specie A or Specie B </u>

P ( A or B ) = ( 8 + 15 ) / 38 = 0.605 ≈ 0.61

<u>C) determine the probability that specie C lizard did not study </u>

P ( not surviving  | C ) = 7 / 15 = 0.466 ≈ 0.47

Reasoning triangle $abc$ has a perimeter of $12$ units. the vertices of the triangle are $a(x,\ 2),\ b(2,-2)$ , and $c(-1,\ 2)$
OlgaM077 [116]

hmmm let's find the distance between B and C first off.

~~~~~~~~~~~~\textit{distance between 2 points} \\\\ B(\stackrel{x_1}{2}~,~\stackrel{y_1}{-2})\qquad C(\stackrel{x_2}{-1}~,~\stackrel{y_2}{2})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ BC=\sqrt{(~~-1 - 2~~)^2 + (~~2 - (-2)~~)^2} \implies BC=\sqrt{(-1 -2)^2 + (2 +2)^2} \\\\\\ BC=\sqrt{( -3 )^2 + ( 4 )^2} \implies BC=\sqrt{ 9 + 16 } \implies BC=\sqrt{ 25 }\implies BC=5

hmmm if BC is that much, then AB + AC = 7, since AB + AC + BC = 12 which is the perimeter, Check the picture below.
