Step-by-step explanation:

Given

2x - 3 > 11 - 5x ( add 5x to both side )

7x - 3 > 11 ( add 3 to both sides )

7x > 14 ( divide both sides by 7 )

x > 2 ← solution

Hence x can be any value greater than 2, that is

x = 3, 4, 5, ......... or

x = 2.1

Answer:

A-(B ⋂ ⋂C)=(A-B) ⋃ ⋃(A-C) If A-B={xlx ∈ ∈A and x ∉ ∉B} A-C={xlx ∈ ∈A and x ∉ ∉C} then (A-B) ⋃ ⋃(A-C)={xlx ∈ ∈A, x ∉ ∉(B and C) Let X=A and Y=(B ⋂ ⋂C) X-Y={xlx ∈ ∈X and x ∉ ∉Y} x ∉ ∉Y x ∉ ∉(B ⋂ ⋂C) x ∉ ∉(B and C) Therefore, A-(B ⋂ ⋂C)=(A-B) ⋃ ⋃(A-C).

Answer:

$ 0.83 on one pound

Step-by-step explanation:

Given: Martha spent $2.90 on 3 1\2 pounds of bananas.

To Find: How much did she spend on each pound of bananas

Solution:

Amount spent by martha on bananas = [tex]\$[/tex] [tex]2.90[/tex]

Quantity of bananas bought                = [tex]3\frac{1}{2}[/tex] [tex]\text{pound}[/tex]

                                                              = [tex]\frac{7}{2}[/tex] [tex]\text{pound}[/tex]

Now,

Martha spent [tex]\$[/tex] [tex]2.90[/tex] on = [tex]\frac{7}{2}[/tex] [tex]\text{pound}[/tex] of bananas

therefore,

Amount spent by Martha on one pound of banana= [tex]\frac{\text{quantity of banana bought}}{\text{Amount spent on bananas}}[/tex]

                                                                        = [tex]\frac{2.90}{\frac{7}{2}}[/tex]

                                                                        = [tex]\frac{2.90\times2}{7}[/tex]

                                                                        = [tex]\$[/tex] [tex]0.83[/tex]

Hence amount spent by martha on one pound of banana is [tex]\$[/tex] [tex]0.83[/tex]

Answer:

64

Step-by-step explanation:

The volume of a prism is defined by the product of its length (L) times its width (W) times its Height (H): [tex]Volume= L * W * H[/tex]

So, if these dimensions are increased each by a factor of 4, the volume now becomes:

[tex]Volume= 4L *4 W * 4 H = 64  L*W*H[/tex]

That is 64 times the original volume LWH

Answer:

64

Step-by-step explanation:

4l x 4w x 4h

the additional is 4 x 4 x 4 = 64

C = 2πr

Divide both sides by 2π.

C/2π = r

Done.

Answer:

2

Step-by-step explanation:

We can find this because it's asking how many times 0.35 goes into 0.7.

Here's an easier example without decimals:

10 / 2 = 5

This is asking how many times 2 goes into 10. The second number in the equation is asking how many times it can go into the first number. In this case, 2 goes into 10 five times.

So in this case, 0.35 goes into 0.7 2 times. To make it easier, you can also do 70 / 35, which makes it easier without the decimals.

Hope this helps!

Answer: 2

Step-by-step explanation:  To divide decimal numbers:

1. If the divisor is not a whole number, move decimal point to right to make it a whole number and move decimal point in dividend the same number of places.

2. Divide as usual. ...

3. Put decimal point directly above decimal point in the dividend.

4. Check your answer for reasonableness.

The "one and a half" is written as 1.5, and "half" is written as 0.5 when using decimal notation.

To write "one and a half" and "half" in numbers, you use the decimal representation. "One and a half" is equivalent to 1.5, and "half" is equivalent to 0.5.

In decimal form, numbers are represented with a whole number portion followed by a decimal point and a fractional portion. The whole number portion is "1" for "one," and the fractional portion is "0.5" for "half." When combined, you get "1.5," which represents "one and a half."

Similarly, for "half," the whole number portion is "0," and the fractional portion is "0.5." When combined, you get "0.5," which represents "half."

To summarize, "one and a half" is written as 1.5, and "half" is written as 0.5 when using decimal notation. These representations are commonly used in mathematics, measurements, and various other contexts for expressing quantities in numeric form.

The question is:

How do you write one and a half, half in numbers?

Answer:

The volume of the box is 3/4 cubic meters.

Step-by-step explanation:

We know that volume = length * width * height. We have length, width, and height already, so all we have to do is multiply.

5/6 * 1 1/8 * 4/5. First we convert 1 1/8 from a mixed fraction, to give us 9/8, as 8/8 = 1.

5/6 * 9/8 * 4/5. 5 * 9 = 45, and 6 * 8 = 48. 45/48 reduces to 15/16.

15/16 * 4/5. 15 * 4 = 60, and 16 * 5 = 80. 60/80 reduces to 6/8, which reduces to 3/4.

Step-by-step explanation:

Answer:

the growth difference would be -3

Step-by-step explanation:

The final elevation of a fish starts at -9 meters and changes -11 meters is -20 meters.

Integers include all whole numbers and negative numbers. This means if we include negative numbers along with whole numbers, we form a set of integers.

Given that, a fish starts at -9 meters and changes -11 meters.

The fish starts at -9 meter than swims down another 11 meters which results in being -20 meters because it is below sea level.

Therefore, the final elevation of a fish starts at -9 meters and changes -11 meters is -20 meters.

Answer: 3rd option

Step-by-step explanation: The answer would be the third option. Let's go through each one and explain why it's correct or incorrect. First of all, our function is y = x - 3 so we can plug numbers into our X and Y. If we follow the function y = x - 3, we have 8 = 10 - 3 which is incorrect for the first one so that can't be it. For the nest one, we have 13 = 10 - 3 which also does not make sense. For the third one, we have 7 = 10 - 3 which is correct. And the last one, we have 3 = 10 - 2 which is wrong. Therefore, the third option is the answer.

Step-by-step explanation:

You round the hundreds place

Final answer:

Rounding the number 427963 to the nearest hundred results in 428000, because the tens digit is 6 which indicates that we should round up.

Explanation:

To round the number 427963 to the nearest hundred, we need to look at the tens digit, which in this case is 6. Since the tens digit is 5 or more, we round up the hundreds place. This means that 427963 rounded to the nearest hundred is 428000.Rounding the number 427963 to the nearest hundred involves examining the tens digit, which is 6.

Since the tens digit is 5 or more, we round up the hundreds place.

Therefore, 427963 rounded to the nearest hundred is 428000.

Answer:

The faster pipe will take 16 hours to fill the pond alone

Step-by-step explanation:

* Lets explain how to solve the problem

- A sewage treatment plant has two inlet pipes to its settling pond

- One pipe can fill the pond 3 times as fast as the other pipe

∴ The rate of the faster pipe is 3 times the rate of the second pipe

- The rate and the time are inverse proportion because;

 time = job/rate and the job here is constant (fill pool), then

 time × rate = constant

∵ The rate of the faster pipe is 3 times the rate of the second pipe

∴ The time of the second pipe is 3 times the time of the faster pipe

- Assume that the time of the faster pipe is t

∵ The time of the faster pipe is t

∴ The time of the second pipe is 3t

- Together they can fill the pond in 12 hours

∴ [tex]\frac{1}{3t}+\frac{1}{t}=\frac{1}{12}[/tex]

- The L.C.M of 3t and t is 3t

∴ [tex]\frac{1}{3t}+\frac{3}{3t}=\frac{1}{12}[/tex]

∴ [tex]\frac{1+3}{3t}=\frac{1}{12}[/tex]

∴ [tex]\frac{4}{3t}=\frac{1}{12}[/tex]

- By using cross multiplication

∴ 48 = 3t

- Divide both sides by 3

∴ t = 16

∵ t represents the time of the faster pipe

∴ The time of the first pipe is 16  hours

* The faster pipe will take 16 hours to fill the pond alone

Final answer:

The faster pipe will take 6 hours to fill the sewage treatment pond by itself, calculated by setting up and solving a rate problem based on the information provided.

Explanation:

To determine how long it will take for the faster pipe to fill the sewage treatment pond alone, we can set up a rate problem where the pipes are filling the pond at their rates and a combined rate.

Let's define the rate of the slower pipe as 1/x ponds per hour (where x is the number of hours it takes the slower pipe alone to fill the pond). This means that the faster pipe works at a rate of 3/x (since it's three times as fast).

Combined, their rate is 1/12 ponds per hour (because together they fill the pond in 12 hours). Our equation will now look like this: 1/x + 3/x = 1/12.

Solving this equation, we find that x, the time it takes for the slower pipe to fill the pond alone, is 18 hours. Therefore, the faster pipe, being three times as fast, will take 18 hours divided by 3, which equals 6 hours to fill the pond alone.

For this case we have to represent the following expression algebraically:

"10 less than x is -45"

So:

10 less than x is represented as: [tex]x-10[/tex]

Then, the complete expression is represented as:

[tex]x-10 = -45[/tex]

Adding 10 to both sides of the equation:

[tex]x = -45 + 10\\x = -35[/tex]

Thus, the value of the variable is [tex]x = -35[/tex]
