What percent of 120 is 42? A. 35% B. 28.6% C. 4.2% D. 33%


i need a step by step explanation

Answers

Answer 1

Answer:

A. 35%

Step-by-step explanation:

You can write 42 of 120 as a fraction ---> 42/120

If you simplify you get 7/20.

7/20 can also be written as 35/100, so the percentage would be 35%.

Answer 2

Answer:

A. 35% BRAINLIEST WOULD BE APPRECIATED!

Step-by-step explanation:

Do guess and check. Start with A.

120*0.35=42 ~ that works! check the others to be sure.

120*0.286=34.272 ~ nope!

120*0.042=don't even need to do it, unreasonable.

120*.33=39.6 ~ nope!

Perfume is sold in two different sizes of bottle. The 80ml bottle is priced at £55. The 50ml bottle is usually priced at £45, but is on special offer. If you buy one 50ml bottle of perfume you can get a second for half price.
By calculating the price per ml determine which offers the best value for money the 80ml or two 50ml bottles ? You must show your working .

Answers

Answer:

Step-by-step explanation:

Price per ml of  80ml bottle= 0.68

price per ml of 50 ml bottle= 0.9

therefore two 50ml bottles is a better deal.

Write an equation of the cosine function with the given amplitude, period, phase shift, and vertical shift. amplitude: 2, period = , phase shift = – , vertical shift = –2

Answers

Answer:

[tex]y=2\cos(2x+\frac{1}{4})-2[/tex]

or

[tex]y=-2\cos(2x+\frac{1}{4})-2[/tex]

Step-by-step explanation:

[tex]y=a cos(c(x-b))+d[/tex] has:

1) amplitude=|a|

2) phase shift=b

3) period=2pi/c

d) vertical shift=d

--------------------------------------------------

You are given the amplitude is 2. This means a could either be 2 or -2.

You are given phase shift is -1/8. This means b is -1/8.

You are given the period is pi. So we need to solve pi=2pi/c.

pi=2pi/c

Dividing both sides by pi gives:

1=2/c

Multiply both sides by c gives:

c=2

The vertical shift is -2 so d=-2.

The equation could either be:

y=2cos(2(x-(-1/8)))-2

or

y=-2cos(2(x-(-1/8)))-2

Simplifying a little gives:

y=2cos(2x+1/4)-2

y=-2cos(2x+1/4)-2

since the slot is 130 cm thick you divide that by the thickness of the candy bar 130/1.5 and then you get 86.6666666.....which rounds to 86 because the slot is not thick enough for another candy bar. good luck on whatever you needed this for!

The table shows the weight of a newborn infant for its first year. During which three-month period was the infant's weight gain the greatest?

0 Months: 7 1/4 lb

3 Months: 12 1/2 lb

6 Months: 16 5/8 lb

9 Months: 19 4/5 lb

12 Months: 23 3/20 lb

Answers

Answer:

12,9,6

Step-by-step explanation:

12=23 3/20. 9=19 4/5. 6=16 5/8.

The infant's weight was gain the greatest during (0 - 3 Months) three-month period.

What is Ratio?

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

The weight gain during (0 - 3 Months) three-month period

⇒ 12 1/2 - 7 1/4 = 25/2 -29/4 = 12.5-7.25 = 5.25 lb

The weight gain during (3 - 6 Months) three-month period

⇒ 16 5/8 - 12 1/2 = 16.625 - 12.5 = 4.125 lb

The weight gain during (6 - 9 Months) three-month period

⇒ 19 4/5 - 16 5/8 = 19.8 - 16.625 = 3.175 lb

The weight gain during (9 - 12 Months) three-month period

⇒ 23 3/20 - 19 4/5 = 23.15 - 19.8 = 3.35 lb

Therefore, the infant's weight was gain the greatest during (0 - 3 Months) three-month period.

Are the sets equivalent? A= {Larry,Moe,Curly,Shemp}. B= {Posh, Sporty,Baby,Scary}

Answers

Answer:

yes

Step-by-step explanation:

equivalent sets have the same number of members

Sets A and B are not equivalent, have the same cardinality but no common elements in their intersection.

The sets A and B are not equivalent because they have different members.

The cardinality of set A is 4, and the cardinality of set B is also 4, meaning they have the same number of elements.

The intersection of sets A and B is the empty set, as they have no common elements.

The expression 146 ÷ 144 is equal to _____.

If f x = x2 + 2x − 5 and g x = 2x + 4, what is (f · g)(x) ?

Answers

Remember that (f*g)(x)= f(x)*g(x). Hope this helps!!!

[tex]\((f \cdot g)(x) = 2x^3 + 8x^2 - 2x - 20 \)[/tex].

To find [tex]\((f \cdot g)(x)\)[/tex], you need to multiply the functions \(f(x)\) and \(g(x)\).

Given:
[tex]\[ f(x) = x^2 + 2x - 5 \]\[ g(x) = 2x + 4 \]To find \( (f \cdot g)(x) \), multiply \( f(x) \) and \( g(x) \):\[ (f \cdot g)(x) = f(x) \cdot g(x) \]\[ (f \cdot g)(x) = (x^2 + 2x - 5) \cdot (2x + 4) \][/tex]

Now, use the distributive property to expand the expression:

[tex]\[ (f \cdot g)(x) = 2x^3 + 4x^2 + 4x^2 + 8x - 10x - 20 \]\[ (f \cdot g)(x) = 2x^3 + 8x^2 - 2x - 20 \][/tex]

So, [tex]\((f \cdot g)(x) = 2x^3 + 8x^2 - 2x - 20 \)[/tex].

Harry needs 21 square meters of fabric for every 6 wizard cloaks he makes. How many cloaks could he make with 7 square meters of fabric

Answers

Answer: 2

Step-by-step explanation:

First, set up a proportion based on the amount of square meters over the number of cloaks he can make:

21/6 = 7/x

Cross multiply to get your next proportion and result with this:

21x = 42

Divide both sides by 21 (always divide the side with the variable):

21x/21 = 42/21

Cancel out the 21 (it's being divided by 21 so that makes it equivalent to 1 so you wind up with just x)

x = 2

Answer: 2

Step-by-step explanation:

Given : Harry needs 21 square meters of fabric for every 6 wizard cloaks he makes.

Using Unitary method , The number of cloaks can be made in 1 square meter fabric will be :-

[tex]6\div21=\dfrac{6}{21}=\dfrac{2}{7}[/tex]

Now , the number of cloaks made in 7 square meters of fabric will be :-

[tex]\dfrac{2}{7}\times7=2[/tex]

Hence, the number of cloaks made in 7 square meters of fabric =2

Given the function f(x) = 3x + 1 and the linear function g(x), which function has a greater value when x = 3?

f(x) is greater.
g(x) is greater.
f(x) and g(x) are the same when x = 3.
g(x) is undefined when x = 3.

Answers

Answer:

f(x) is greater.

Step-by-step explanation:

if you replace the x on f(x)=3x+1 with the 3 for x=3 its 3×3+1. 3 times three is 9 plus 9 with one is 10, and the line hits 6.9

The  function that has a greater value when x = 3 is option A: f(x) is greater.

What is the function

The function [tex]\(f(x) = 3x + 1\)[/tex] is a linear function with a slope of 3 and a y-intercept of 1. The function[tex]\(g(x)\)[/tex] is not explicitly provided in your question, so we don't have information about its slope or intercept.

To determine which function has a greater value when x = , we need to evaluate both functions at x = 3 and compare their values.

So, when one replace the x on f(x)=3x+1 with the 3 for x=3 its 3×3+1. 3 times three is 9 plus 9 with one is 10, and the line hits 6.9

Use the commutative property of addition to write an equivalent algebraic expression

Answers

Answer:

9(x+5)=9(5+x)

Step-by-step explanation:

This is tricky because you were probably thrown off by the multiplication step from the parentheses. Since the question wants you to demonstrate your knowledge of the commutative property of addition, you will only worry about inside the parentheses.

So, the commutative property is basically just moving numbers/variables around the addition sign to show that the answer will remain the same either way.

Because of this, we can simply move the (x+5) around to (5+x).

Final answer: 9(x+5)=9(5+x)
