What is the ratio of 50 cents to $1.20 (in simplest form)?
Answer:
5/12
Step-by-step explanation:
because $1 = 100 cents
ratio = 50 cents / ($1.2 x 100) = 5/12
just convert to the same currency
The ratio of 50 cents to $1.20 is [tex]\frac{5}{12}[/tex]
What is ratio?'A ratio can be defined as the comparison between two numbers of the same unit to check how bigger is one number than the other one.
According to the given problem,
Amount in cents = 50 cents
= 0.5 dollars
Amount in dollars = $1.2
Ratio = [tex]\frac{0.5}{1.2}[/tex]
= [tex]\frac{5}{12}[/tex]
Hence, we can conclude, the ratio is [tex]\frac{5}{12}[/tex].

15. If 2x + 3 is a factor of a polynomial f(x),
which of the following statements is true?
A. 3/2 is a zero of f(x)
B. -3/2 is a root of f(x)
C. f(-2/3) = 0
D. (2/3, 0) is an x-intercept
Answer:
B
Step-by-step explanation:
2x+3 is a factor of f(x) means that f(x) = (2x+3)* something else
to find the root or the zero:
2x+3 = 0 so 2x = -3; x= -3/2 so B is correct
Please help! Math is my worst subject
Answer:
it's answer is 73°
Step-by-step explanation:
< DCB = 50°
< ACB = x
< CAB = 57°
< ABC = < DCB = 50° {Being alternate angles }
Now
x + 50° + 57° = 180° { being sum of angles of triangle }
x + 107° = 180°
x = 180° - 107°
Therefore x = 73°
Hope it will help :)❤

After jumping rope for 15 minutes, Jan took a break. If Jan took a break at 3:05 p.M., at what time did she start jumping rope?
Answer: 2 : 50 pm
Step-by-step explanation:
If Jan took a break at 3:05 pm and she had been jumping rope for 15 minutes before that, to find the time she started jumping rope, subtract 15 from the current time:
= 3:05 - 15
= 2:50 pm
Jan started jumping rope at 2 : 50 pm

Use the function below to find F(3). F(x)=(1/6)x A. 1/18 B. 1/216 C. 1/2 D. 1/72

C
Step-by-step explanation:
To evaluate f(3) substitute x = 3 into f(x), that is
f(3) = [tex]\frac{1}{6}[/tex] × 3 = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex] → C
If x = -3 evaluate the following expression

Step-by-step explanation:
you have to substitute x with -3, so where you see x in the equation you write a -3 and calculate
[tex]\frac{(x-2)(x+9)}{x(x+5)} = \frac{(-3-2)(-3+9)}{-3(-3+5)} = \frac{-5*6}{-3*2} =\frac{-5}{-1} =5[/tex]

A company is making two types of covered aluminum containers. One is a cylinder with a height of 114feet and a diameter of 1 foot. The other is a rectangular prism with a length of 34foot, a width of 34foot, and a height of 1 foot. How much greater is a cylinder's capacity?
Answer:
[tex]V_d=976.9ft[/tex]
Step-by-step explanation:
From the question we are told that:
Height of cylinder h_1=114 feet
Diameter d=1
Length of triangular prism [tex]l_2=34ft[/tex]
Width of triangular prism [tex]w_2=34ft[/tex]
Height of triangular prism [tex]h_2=1 ft[/tex]
Generally the equation for Volume of the cylinder is mathematically given by
[tex]V_c=\pir^2h[/tex]
Where
[tex]r=d/2\\r=0.5[/tex]
Therefore
[tex]V_c-=\pi*0.5*114[/tex]
[tex]V_c=57\pi[/tex]
[tex]V_c=179.1ft[/tex]
Generally the equation for Volume of a Rectangular prism is mathematically given by
[tex]V_r=whl[/tex]
[tex]V_r=34*34*1[/tex]
[tex]V_r=1156feet[/tex]
Generally the equation for Volume difference is mathematically given by
[tex]V_d=V_r-V_c[/tex]
[tex]V_d=1156-179.1[/tex]
[tex]V_d=976.9ft[/tex]
