Answer:

No, they are not.

Step-by-step explanation:

A ratio can be written as a fraction. So 3:5 is the same as 3/5 and 2:4 is the same as 2/4.

3/5 = 2/4

0.6 = 0.5 INCORRECT

As you can see, the both don't equal the same numbers, so they aren't equivalent.

Question:- 22% of 150

Answer:-

[tex]22\% \: of \: 150[/tex]

In maths of means multiplication

[tex] \frac{22}{100} \times 150 \\ \frac{ \cancel{22}^{ \: \: \tiny{11}} }{ \cancel{100} {}^{\tiny{ \: \: 50}}} \times 150 \\ \frac{11}{ \cancel{50}^{ \: \: 1} } \times \cancel{150}^{ \: \: 3} \\ 11 \times 3 = 33[/tex]

Correct options is (D) 33

The value of 22 percentage of 150 is 33, option D is correct.

To find 22% of 150, we need to convert the percentage to a decimal and then multiply the result with 100.

Convert the percentage to a decimal.

To convert a percentage to a decimal, you divide it by 100.

In this case, 22% as a decimal:

= 22 ÷ 100

The result is 0.22.

= 0.22

Multiply the decimal by the number (150) you want to find the percentage of.

In this case, 0.22 (the decimal equivalent of 22%) multiplied by 150:

=150×0.22

=33

Therefore, the value of 22% of 150 is equal to 33. option D is correct.

Answer:Integer Numbers?

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

they're the same triangle, but one is bigger. the 2,5 and 5 sides are equivalent, so with that we are able to know the big triangle is exactly 2x bigger. u multiply the 2 side (because it's equivalent to the x side) by 2 (bc the triangle is 2 times bigger) and you get 4 = x

Answer:

x<-7

Step-by-step explanation:

4 − (x + 2) < −3(x + 4)

4 − x - 2< −3x - 12

14 < - 2x

x<-7

Answer and Step-by-step explanation:

First, we need to solve both sides of the equation.

Distribute the negative to the x and the 2.

4 - x - 2 < -3(x + 4)

Distribute the -3 to the x and the 4.

4 - x - 2 < -3x - 12

Combine like terms.

2 - x < -3x - 12

Add 12 to both sides of the equation.

12 + 2 - x < -3x - 12 + 12

14 - x < -3x

Add x to both sides of the equation.

14 - x + x < -3x + x

14 < -2x

*Divide both sides of the equation by -2, and flip the sign.

-7 > x

-7 > x is the answer.

*How this works:

When we flip the sign, we really are just saving ourselves an extra step when dividing numbers (that are negative, only works when number is negative).

14 < -2x

If we were to add to x, and subtract 14, it will look like this:

2x < -14

Then when we divide by 2, we get:

x < -7

This is the same result, but it takes an extra step. Use this way if you forget why you need to flip the sign when dividing by a negative number.

Answer: Thrid choice. 4

Step-by-step explanation:

Given equation

(-3/4)m - (1/2) = 2 + (1/4)m

The least common multiple of the denominator

First three multiples of 2: 2, 4, 6

First three multiples of 4: 4, 8, 12

Since 4 is the first common multiple, 4 is the least common multiple of 2 and 4.

By multiplying [tex]\boxed{4}[/tex] on both sides, the fraction can be eliminated.

Answer: x+5/8 = 1 is the equation where x is the remaining coffee.

Step-by-step explanation:

he drank = 5/8

whole coffee = 1

so

let coffee remaining be x

1-5/8 = x

x+5/8 = 1

The required equation, for the remaining cup of coffee, is x = 1+(- 5/8).

To determine the addition equation of coffee remaining in the cup, for the condition Kelly bought a cup of coffee and drank 5/8 it.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the coffee remaining in the cup be x,
Now, according to the question,
1 = x + 5/8
x = 1 - 5/8
For the addition equation,
x = 1 +(-5/8)

Thus, the required equation, for the remaining cup of coffee, is x = 1+(- 5/8).

The three possible sets of integers whose product is -7 are:

1. (1, 1, -7) (least to greatest)

2. (-1, 1, 7) (least to greatest)

3. (-1, -1, 7) (least to greatest)

To find the three possible sets of integers whose product is -7, we need to consider all the combinations of three integers whose product results in -7. Keep in mind that each set should use unique integers. Let's explore the options:

1. Set 1: [tex]\(1 \times 1 \times -7 = -7\)[/tex]

2. Set 2: [tex]\((-1) \times 1 \times 7 = -7\)[/tex]

3. Set 3: [tex]\((-1) \times (-1) \times 7 = -7\)[/tex]

The three possible sets of integers whose product is -7 are:

1. (1, 1, -7) (least to greatest)

2. (-1, 1, 7) (least to greatest)

Step-by-step explanation:

2*3=6

4*3=12

5*3=15

8*3=24

Step-by-step explanation:

a) is really easy, right ?

the surface area consists of 6 rectangles (as you know, every die has 6 sides). they are 3 pairs of equally sized rectangles.

there are 2 rectangles 7×1, 2 rectangles 7×2, and 2 rectangles 2×1

SA = 2×7×1 + 2×7×2 + 2×2×1 = 14 + 28 + 4 = 46 in²

the volume is just length×width×height

V = 7×2×1 = 14 in³

b)

a little bit more difficult, but with a little trick just as easy.

the surface area consists of the 2 circle areas and the mantle "coating".

the area of a circle is pi×r².

we have to be careful as the given 10 ft is the diameter of these circles. the radius is half of it : 5 ft.

the area of the "mantle" we can calculate by imagining we simply slice it open with one straight line from top to bottom. and then we cut it off the two circles and put it flat on the table.

now we see it is just a rectangle. one side is 12ft. the other is the circumference of the previously attached circles.

circumference of a circle is 2×pi×r

so the surface area is 2×circle + (circumference circle)×12

SA = 2×pi×5² + (2×pi×5)×12 = 50pi + 120pi = 170pi =

≈ 534.07 ft²

the volume is one base area (circle) times height

V = pi×5²×12 = 300pi ≈ 942.48 ft³
