What is the answer for x

Answer: 12.5 tomatoes

Step-by-step explanation:

You know that the recipe for 4 servings requires 5 tomatoes and you want to make chili for 10 servings. Therefore, to calculate the amount of tomatoes required for this, you should use the following conversion factor:

[tex]\frac{5\ tomatoes}{4\ servings}[/tex]

Now multiply the conversion factor by the 10 servings:

[tex]=(10\ servings)(\frac{5\ tomatoes}{4\ servings})\\=12.5\ tomatoes[/tex]

Therefore, you will use 12.5 tomatoes to make 10 servings.

Answer:

Tomatoes for 10-servings = 12.5

Step-by-step explanation:

Given

Number of tomatoes for 4 servings = 5

So we can calculate the number of tomatoes for one serving by dividing the serving by number of tomatoes.

So,

Number of tomato for one serving = 5/4

= 1.25

Now we can calculate the number of tomatoes for 10 servings

Number of tomatoes for 10 servings = Number of tomatoes for one serving * 10

= 1.25 * 10

= 12.5 tomatoes

Step-by-step explanation:

"What number" means a variable, like x.

"Is" means equals.

"Less than" means subtracted from.

Percent means out of 100.

"Of" means multiplication.

x = (150/100) 80 - 20

x = 120 - 20

Answer:

7

Step-by-step explanation:

The given algebraic expression is;

[tex]-x^2-6y+13x+7[/tex]

This is an algebraic expression in x and y.

Any term that is independent  of these two variables is called the constant term.

The term '7' is independent  of these variables.

Hence the constant term is 7.

The answer is:

{-5<x<5}

To solve the problem, we need to remember how Absolute Value Functions behave, when we have this type of function, related to an inequality, the solution will be between two values.

We are given the inequality:

[tex]|x|<5[/tex]

So, we know that "x" will be between -5 and 5:

[tex]-5<x<5[/tex]

Hence, the solution of the given inequality will be:

(-5,5) or {-5<x<5}

Answer:

the means absolute deviation is 1.8

the striking deviation is 7

(it is because the data point on the far right of the graph)

Step-by-step explanation:

calculate the absolute deviation:

1.  calculate the mean (add all numbers and divide by 10) = 2.6

2.  find the absolute value of each

2.6 - 0 = 2.6

2.6 - 1 = 1.6 (you have 1's 4 times so each one will be 1.6)

2.6 - 3 = 0.4

2.6 - 4 = 1.4 (you have 4's 3 times)

2.6 - 7 = 4.4

3.  Then add all of those values together

2.6 + 1.6 + 1.6 + 1.6 +  1.6 + 0.4 + 1.4 + 1.4 + 1.4 + 7.4 = 18

4.  find the mean of the difference

Answer:

On second day: 500 cm^3

On third day: 250 cm^3

Step-by-step explanation:

Let x be the initial amount of helium gas in the balloon.

As it is mentioned in the question that the balloon loses half of it's gas in one day. So after one day the gas will be half of the current volume. And to calculate the volume of gas the next day, the reduced volume will be divided by two.

So,

x = 1000 cm^3

Volume on second day,

x1 = 1000/2

=> 500 cm^3

Volume of gas on third day

x2 = x1/2

=> 500/2

=> 250 cm^3

Answer:

the answer is 500cm^3 and 250cm^3

Answer:

f(x) = (x + 4)² - 13

Step-by-step explanation:

You will have to "complete the square [½B]²" to figure this out. Here is how you would set it up:

(x + 4)² → x² + 8x + 16

x² + 8x + 16 - 13 → x² + 8x + 3 [TA DA!]

We know that our vertex formula is correct. Additionally, that -h gives you the OPPOSITE terms of what they really are, and k gives you the EXACT terms of what they really are. Therefore, your vertex is [-4, -13].

To simplify the expression -(5-3v) using the distributive property, distribute the negative sign to each term inside the parentheses and combine like terms.

To simplify the expression -(5-3v) using the distributive property, we need to distribute the negative sign to each term inside the parentheses. This means we will multiply -1 by both 5 and -3v.

The distributive property states that for any numbers a, b, and c, a(b + c) is equal to ab + ac. Applying this property to our expression, we get -(5) - (-3v), which simplifies to -5 + 3v.

Therefore, the simplified expression is -5 + 3v.

Answer:

Step-by-step explanation:

In this problem, you have to work sort of backwards.

The mean is 2.3 and there are 6 numbers [including this missing one] so multiply 2.3 by 6.

2.3 x 6 = 13.8

Now, subtract the 5 values you know from 13.8

13.8 - 2.3 - 4.1 - 1.2 - 1 - 0.5 = 4.7

Thus, the missing value is 4.7

What is Proportion

A proportion is an equation stating that two rational expressions are equal. Simple proportions can be solved by applying the cross products rule.

If [tex]\frac{a}{b} = \frac{c}{d}[/tex] then ab = bc.

What is Direct variation?

The phrase “ y varies directly as x” or “ y is directly proportional to x” means that as x gets bigger, so does y, and as x gets smaller, so does y. That concept can be translated in two ways.

[tex]\frac{y}{x} = k[/tex] for some constant k.

The k is called the constant of proportionality. This translation is used when the constant is the desired result.

What is Inverse Proportion?

According to the expressions "y varies inversely as x" and "y is inversely proportionate to x," y decreases as x increases or vice versa. There are two translations for this idea. For any constant k, referred to as the constant of proportionality, yx = k. If the constant is wanted, use this translation.

What is Joint Variation?

Joint variation is the term used to describe when one variable changes as the sum of other variables. There are two translations for the phrase "y fluctuates concurrently as x and z."

So, In the given question:

Weight that a rectangular beam can support varies jointly as its width and the square of its height and inversely as its length;

It is in joint proportion;

[tex]\begin{aligned}&\mathbf{W}=\frac{\mathbf{w h}^2}{\mathbf{L}} \\&\left\{\begin{array}{l}w=\frac{1}{4} \\h=\frac{1}{3} \\L=12 \\W=30\end{array} \quad \Longrightarrow 30=\frac{\mathbf{k} \frac{1}{4}\left(\frac{1}{3}\right)^2}{12}\right.\end{aligned}[/tex]

[tex]360=\frac{\mathrm{k}}{36} \Longrightarrow 12960=\mathrm{k}[/tex]

Now,

[tex]\text { when }\left\{\begin{array}{l}w=\frac{1}{4} \\h=\frac{1}{2} \\L=12\end{array}\right.[/tex]

[tex]W=\frac{12960\left(\frac{1}{4}\right)\left(\frac{1}{2}\right)^2}{12}[/tex]

[tex]W=1080\left(\frac{1}{4}\right)\left(\frac{1}{4}\right) \\\Longrightarrow W=1080 \cdot \frac{1}{16}[/tex]

[tex]\\\Longrightarrow\mathrm{W}=\frac{135}{2} \\\Longrightarrow \mathrm{W}=67 \frac{1}{2}[/tex]

Hence, A similar beam can support [tex]67 \frac{1}{2}[/tex] feet if the beam is one-fourth foot wide and a half a foot high, and 12 feet long.

Answer:

x= 4-7i  x= 4+ 7i

Step-by-step explanation:

step 1 : make equation = 0

[tex]x^{2}[/tex] - 8x + 65 = 0

step 2 : solve for x [ using the quadratic equation]

ie :     x = -b ± [tex]\sqrt{b^{2}-4ac}[/tex] / 2a

so it will look like this

x= -(-8) ± [tex]\sqrt{(-8)^{2} - 4(1)(65)}[/tex] /2(1)

when you simplify you wont be able to root the -196 so you will have to separate the roots

x = 8 ±( [tex]\sqrt{-1}[/tex] )( [tex]\sqrt{196}[/tex]) / 2

now there is a rule for negative roots whereby  [tex]\sqrt{-1}[/tex] is equivalent to i so now you will change [tex]\sqrt{-1}[/tex] into i

Simplify [tex]\sqrt{196}[/tex]

which will give you 14

now place all the new values into the formula

8 ± 14i /2

you can then further simplify to  

4 ± 7i

step 3 : separate

this will give you the final answer of

Median = 18

Step-by-step explanation:

The median is the middle number if the elements (prices)  are arranged from least to greatest.

let's arrange the prices of watches from least to greatest:

12, 15, 16, 16, 20, 22, 24 27

Since there are even number of numbers (8), the median is the value between 4th and 5th numbers.

4th number is 16

5th number is 20

We need the value between 16 and 20. We get that by adding these 2 and dividing by 2:

16 + 20 = 36

36/2 = 18

THus, median = 18
