Mathematics

Naily [24]3 years ago
8 0

Answer:

In this case, you can simply treat the > sign like an = sign.  The only time you would need to worry about is when multiplying or dividing by negative numbers.

2x + 3 > 13

2x + 3 - 3 > 13 - 3

2x > 10

2x / 2 > 10 / 2

x > 5

Answer:

20. 13 cm

21. 12 cm

Step-by-step explanation:

20. isosceles means two sides are the same length, so you take the ten off the perimeter to get 26 remaining cm (36 -10) and you then divide that by two to get both sides of 13 cm (26 / 2)

21. because you know that if you split the triangle down the middle you get a right triangle and you can use a^2+b^2=c^2 to find the height, so we take the one side of 13 cm and half of the third side, which is 5, and you can find your answer (a^2 + 5^2 = 13^2   ---> a^2 + 25 = 169 ---> a^2 = 144 ---> a = 12)

Has anyone done Exponential Growth and Decay (in mathematical models with application A) on sos or odysseware and gotten a prefe
Lilit [14]

Answer:

1) 62.5

2) 50

3) 75

4) 100

Step-by-step explanation:

1)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After 25*4=100 days, there will be (1/2)^{4}=1/2^{4}=1/16 of it left.

So, 1000/16=\boxed{62.5}.

2)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After 25*3=75 days, there will be (1/2)^{3}=1/2^{3}=1/8 of it left.

So, 400/8=\boxed{50}

3)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After 25*2=50 days, there will be (1/2)^2=1/2^{2}=1/4 of it left.

So, 300/4=\boxed{75}.

4)

The only answer left is \boxed{100} grams. You can solve it the same way you solved the previous steps.

Solve for d:<br> 2d+1/6=6(1/3d+1)
taurus [48]
2d+1/6=2d+6 (I distributed the 6 to what was in the parentheses)
2d-2d=6-1/6 (I subtracted 2d from both sides to get the variables on one side and               1/6 from both sides to get the variables by themselves)
0=35/6 (combined like terms)
0=35/6 is an untrue statement so x doesn't exist
