The average newborn baby weighs 7.0 pounds, give or take 1 pound. The average newborn hippopotamus weighs 40 pounds, give or take 1 pound. Which statement is true about the percent error of each of the two newborns?
a. A newborn baby has a smaller percent error
b. A newborn hippopotamus has a smaller percent error
c. Both newborns have the same percent error
d. There is not enough information to decide
Answers
Answer:
B
Step-by-step explanation:
since the average newborn hippopotamus has a larger weight, if you give or take one pound, the percent error will not make as much of a difference as it would with the weight of an average newborn baby (7 pounds). therefore, a newborn hippopotamus has a smaller percent error.

X=15 than you just plug it in for each angle
Answer:
∠A = 60°
∠B = 42°
∠C = 78°
Step-by-step explanation:
∵ In a triangle, sum of all the three interior angles is 180°
∴ m∠A + m∠B + m∠C = 180°
∴ (4x)° + (3x - 3)° + (5x + 3)° = 180°
∴ (4x + 3x - 3 + 5x + 3)° = 180°
∴ (12x)° = 180°
∴ 12x = 180
∴ x = 180/12
∴ x = 15
∠A = (4x)° = (4× 15)° = 60°
∠B = (3x-3)° = (3× 15-3)° =(45-3)°= 42°
∠C = (5x+3)° = (5× 15 + 3)° =(75 + 3)°= 78°

C. Add 6·x + 3·y = -24 to 6·x - 2·y = -4
Step-by-step explanation:
To show that given a a system of two equations in (having) two unknowns, when one of the equations is replaced by the sum the equation being replaced and the multiple of the other equation gives a system with the same solution as the previous system, we proceed as follows;
The given system of equations are;
6·x - 2·y = -4
2·x + y = -8
Gabriela multiplies the second equation by 3, to get;
3 × (2·x + y) = 3 ×-8 = -24
6·x + 3·y = -24
She should add the equation above to the first equation to get;
Add 6·x + 3·y = -24 to 6·x - 2·y = -4
(6·x + 3·y) + (6·x - 2·y) = -24 + -4
12·x + y = -24
The new system becomes;
12·x + y = -28
2·x + y = -8
Subtracting the second equation from the first equation in the new system gives;
12·x + y - (2·x + y) = -28 - (-8) = -28 + 8 = -20
10·x + y - y = 10·x + 0 = -20
x = -20/10 = -2
From the second equation, we get;
y = -8 - 2·x = -8 - 2×(-2) = -4
y = -4
We verify if the solution is the same as the first system as follows;
6·x - 2·y = -4
2·x + y = -8
Therefore
6·(-2) - 2·(-4) = -4 (Correct)
2·(-2) + (-4) = -8 (Correct)
Therefore, the next step is to add 6·x + 3·y = -24 to 6·x - 2·y = -4

The half-life of a certain radioactive material is 83 hours. An initial amount of the material has a mass of 67 kg. Write an exponential function that models the decay of this material. Find how much radioactive material remains after 5 hours. Round the answer to the nearest thousandth.
Answers
Answer:
Initial amount of the material is 67 kgHal-life is 83 hoursThe required equation is:
m(x) = 67 * [tex](1/2)^{x/83}[/tex], where m- remaining amount of the radioactive material, x - number of hoursAfter 5 hours the material remains:
m(5) = 67 * [tex](1/2)^{5/83}[/tex] = 64.260 (rounded)

Consider the figure shown below. How long is HG?
Answers
Answer:
HG = 2[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos60° = [tex]\frac{1}{2}[/tex] , then
cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{GI}{HG}[/tex] = [tex]\frac{\sqrt{2} }{HG}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
HG = 2[tex]\sqrt{2}[/tex]
Use trigonometry.
Angle H = 30 degrees
sin (30) = sqrt{2}/HG
HG = sqrt{2}/sin (30)
HG = 2.8284271248
HG = 2•sqrt{2}
