1. A newborn giraffe weighs about 65 kilograms. How much does it weigh in grams?
65 kg = 65*1000 g = 65000 g2. The average height of a female giraffe is 4.6 meters. What is her height in centimeters?
4.6 m = 4.6*100 cm = 460 cm3. The capacity of a beaker is 0.1 liter. Convert this to milliliters.
0.1 l = 0.1*1000 ml = 100 ml4. A pig weighs 9.8 pounds. Convert the pig’s weight to ounces.
9.8 pounds = 9.8*16 ounces = 156.8 ounces5. A marker is 0.13 meters long. What is the length in millimeters?

Which of the following functions have y-axis symmetry?
a y=x^2,y= |x|, y= cos(x)
b y=sinx, y = cos x, y = x, y = x^3
c. y=x, y=x^3, y=1/x, y=cos x
d. y=1/x, y=sin x, y=x^2
The plot of a function f(x) is symmetric across the y-axis if it is even, meaning f(-x) = f(x) for all x in the function's domain.
The answer is then A because
(-x)² = (-1)² x² = x²
|-x| = |-1| |x| = |x|
cos(-x) = cos(x)
The answer is not
• B because sin(-x) = -sin(x) and (-x)³ = (-1)³ x³ = -x³
• C because -x ≠ x and again because of x³
• D because 1/(-x) = -1/x and again because of sin(x)

Possible rational zeros are of the form ...
±{divisor of the constant term}/{divisor of the leading coefficient}
__
1. Rational zeros will be one of ±{1, 2, 3, 6, 9, 18}/{1, 2}, so will be ...
{±1/2, ±1, ±3/2, ±2, ±3, ±9/2, ±6, ±9, ±18}
__
2. Rational zeros will be one of {±1, ±2, ±3, ±4, ±6, ±8, ±12 ±24}.
__
3. The pairs of coefficients suggest factoring by pairs:
f(x) = (2x^3 +2x^2) -(8x +8) = 2x^2(x +1) -8(x +1) = 2(x^2 -4)(x +1)
f(x) = 2(x -2)(x +2)(x +1)
Zeros of f(x) are 2, -2, -1, values of x that make the factors zero.
__
4. The sum of coefficients is zero, so x=1 is a zero. Factoring that out by any of several means, you find ...
f(x) = (x -1)(x^2 +2x -8)
The quadratic is factored by looking for factors of -8 that have a sum of 2. (4 and -2 are those)
f(x) = (x -1)(x +4)(x -2)
Zeros of f(x) are 1, -4, 2.

At a local department store, skirts typically cost $15. However, due to a special, the
skirts are reduced to $3. What percent of the original price has the skirts been reduced
to?
Answer: 20%
Step-by-step explanation:
(part / whole) * 100
(3 / 15) * 100 = 20%
The skirts have been reduced to 20% of their original price.
You are looking for the percentage of the original price that the new price is. This means that you are looking for what percentage of $15 that $3 is:
= New price / Original price x 100%
= 3 / 15 x 100%
= 1/5 x 100%
= 20%
The skirts have therefore been reduced to 20% of their original price.

(4, 4)
(1, −10)
(2, 4)
(−2, 0)
Answer:
(2,4) is the correct answer
Step-by-step explanation:
In order to solve two inequalities, we have to graph the two inequalities on the graph. We have used the online graphing calculator "Desmos' for this purpose.
When two inequalities are graphed, the area that is common in both inequalities is the solution of the system.
We have to observe the graph to check if given points are in solution set of the system.
In the given points, (2,4) lie in the solution set as indicated in the picture.
Hence,

A prism with a base area of 3 m2 and a height of 4 m is dilated by a factor of 3/2
What is the volume of the dilated prism?
Enter your answer, as a
decimal, in the box.
х
Answer:
The value of the new volume 'x' would be equal to 40.5 cm³.
Step-by-step explanation:
Given
base area = 3 m²height = 4mDilation by a factor scale of 3/2.We can determine the volume of the original prism by multiplying the area of the base by the height,
volume = (3 cm²)(4 cm) = 12 cm³
Dilation by a factor of 3/2 means that the dimensions of the new prism is 3/2 times that of the original object.
let 'x' be the volume of the new solid,
[tex]\frac{x}{12}=\left(\frac{3}{2}\right)^3[/tex]
[tex]\frac{x}{12}=\frac{27}{8}[/tex]
Multiply both sides by 12
[tex]\frac{12x}{12}=\frac{27\cdot \:12}{8}[/tex]
[tex]x=\frac{81}{2}[/tex]
[tex]x=40.5[/tex] cm³
Therefore, the value of the new volume 'x' would be equal to 40.5 cm³.

then put x back in to solve for y
C. no because that is a whole 10 minutes more so it would be for 160 minutes of practice instead.
Step-by-step explanation:
this is my first time answering a question so hope it helps :)
A pair of linear equations to show the relationship between the number of minutes ;
x=Max practices the guitar
y= the number of minutes he practices the piano
Pair of equation are :x+y=150
y=x+80
Part B:The time does Max spend practicing the piano every day:
x=35 y=115 x + (x + 80) = 150 2x + 80 = 150 2x = 70 x =35Subsitute x back in to solve for y.
x+y=150
35+y=150
y=115
Part C:No , it is not possible because that is a whole 10 minutes more so it would be for 160 minutes of practice instead.
