Answer:

3x+12=57

x= how many days

Step-by-step explanation:

Answer:

[tex]3x+12=57[/tex]

Step-by-step explanation:

Let x represent number of days.

We have been given that Marco earns $3 per day working. So amount earned in x days would be [tex]3x[/tex].

We are also told that Marco already has $12 saved, so total amount saved by Marco in x days would be [tex]3x+12[/tex].

Now we will equate total amount saved by Marco in x days with 57 as Marco needs to save $57 to buy new shoes.

[tex]3x+12=57[/tex]

Therefore, the equation [tex]3x+12=57[/tex] shows the number of days (x) that Marco must work before he can afford the shoes.

Answer:

The width of the rectangular space  = 5 ft.

Step-by-step explanation:

The area of the rectangular space = 70 sq ft.

The length of the rectangular space = 14 ft

The width of the rectangular space - m ft

Now, AREA OF THE RECTANGLE  = LENGTH x WIDTH

⇒  70 sq ft.  =  14 ft x m ft

or, m =  70 / 14  = 5 ft

or, m = 5 ft

Hence the width of the rectangular space  = 5 ft.

Answer:-4 2/3

Step-by-step explanation: negative number minus itself will always be positive.

Answer:

those are the dimentions

Step-by-step explanation:

The missing values are [tex]\( a = 2 \), \( b = 0 \), and \( c = -24 \),[/tex] yielding the factored form [tex]\( 2x(x - 24) \).[/tex]

To find the missing values of[tex]\( a \), \( b \), and \( c \)[/tex], we need to expand the polynomial [tex]\( (x+b)(x+c) \)[/tex]and equate it to [tex]\( 2x^3 - 8x^2 - 24x \).[/tex]

Expanding [tex]\( (x+b)(x+c) \),[/tex] we get:

[tex]\[ (x+b)(x+c) = x^2 + (b+c)x + bc \][/tex]

Comparing this to [tex]\( 2x^3 - 8x^2 - 24x \),[/tex]we see that:

[tex]\[ x^2 + (b+c)x + bc = 2x^3 - 8x^2 - 24x \][/tex]

We need to match the coefficients of corresponding terms on both sides of the equation.

From the equation above, we can equate coefficients:

1. Coefficient of [tex]\( x^3 \): \( 2 = 0 \)[/tex] (there is no [tex]\( x^3 \)[/tex] term on the right side).

2. Coefficient of [tex]\( x^2 \): \( 1 = -8 \) (from \( x^2 \) term)[/tex].

3. Coefficient of [tex]\( x \): \( b + c = -24 \) (from \( x \) term).[/tex]

4. Constant term: [tex]\( bc = 0 \)[/tex] (there is no constant term on the right side).

From the last equation, we know that either [tex]\( b \) or \( c \)[/tex]must be zero, or both.

If one of them is zero, then the other must be equal to [tex]\( -24 \)[/tex] for the equation [tex]\( b + c = -24 \)[/tex] to hold true.

Now, we can test some values to satisfy these equations:

1. If [tex]\( b = 0 \)[/tex]

  [tex]\[ c = -24 \][/tex]

2. If [tex]\( c = 0 \):[/tex]

[tex]\[ b = -24 \][/tex]

3. If both [tex]\( b \) and \( c \)[/tex]are non-zero:

  We can solve the equation [tex]\( b + c = -24 \)[/tex] for various values of [tex]\( b \) and \( c \).[/tex]

Therefore, possible combinations are:

1.[tex]\( a = 2 \), \( b = 0 \), \( c = -24 \)[/tex]

2.[tex]\( a = 2 \), \( b = -24 \), \( c = 0 \)[/tex]

3.[tex]\( a = 2 \), \( b = -12 \), \( c = -12 \)[/tex]

So, the possible missing values are:

1. [tex]\( a = 2 \), \( b = 0 \), \( c = -24 \)[/tex]

2. [tex]\( a = 2 \), \( b = -24 \), \( c = 0 \)[/tex]

3.[tex]\( a = 2 \), \( b = -12 \), \( c = -12 \)[/tex]

Answer:

4000 is size of a crowd walking in a charity fundraising March.

Step-by-step explanation:

Given:

Dimensions of rectangular space 10 feet by 12000 feet

So we can say that,

Length = 1200 ft

Width = 10 ft

Now we will calculate the area of rectangular space which is given by

Hence Area will be = [tex]length\times width= 10\ ft \times 1200 \ ft= 12000 \ ft^2[/tex]

Now we know that 40 people occupy a rectangle measuring 10 feet by 12 feet.

Length = 12 ft

Width = 10 ft

Area = [tex]length\times width= 10\ ft \times 12 \ ft= 120 \ ft^2[/tex]

It says that 40 people are occupied in 120 [tex]ft^2[/tex]

So how many people will be there in 12000 [tex]ft^2[/tex]

By using unitary method we get,

Number of people = [tex]\frac{40\times 12000 \ ft^2}{120 \ ft^2} = 4000 \ peoples[/tex]

Size of a crowd walking in a charity fundraising March is 4000.

Answer:

4,000 people

Step-by-step explanation:

49 people occupy 120 ft^2

Dimensions of crowd: 10×1,200=12,000

120 ft^2/40 people = 12,000 ft^2/x people

Answer:

[tex]x = 1000[/tex] or [tex]x = 0.01[/tex]

Step-by-step explanation:

We are given a logarithmic equation of x and we have to solve it for x.

Given,

[tex]x^{\log x} = 1000000x[/tex]

⇒ [tex]x^{\log x} = 10^{6} \times x[/tex]

Now, taking log on both sides, we get

[tex]\log x^{\log x} = \log 10^{6} \times x[/tex]

⇒ [tex]\log x .\log x = \log 10^{6}  + \log x[/tex]

{Since [tex]\log a^{b} = b\log a[/tex] and [tex]\log ab = \log a + \log b[/tex]}

⇒ [tex](\log x)^{2} = 6 + \log x[/tex]

{Since log 10 = 1}

⇒ a² = 6 + a {Where, a = log x}

⇒ a² - a - 6 = 0

⇒ (a - 3)(a + 2) = 0

⇒ a = 3 or a = -2

⇒ [tex]\log x = 3[/tex] or [tex]\log x = - 2[/tex]

Now, converting logarithm to exponential form, we get,

⇒ [tex]x = 10^{3} = 1000[/tex] or [tex]x = 10^{- 2} = \frac{1}{100} = 0.01[/tex] (Answer)

Answer:

[tex] ME=1.64\sqrt{\frac{0.07(1-0.07)}{370}}=0.0218[/tex]

Step-by-step explanation:

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".  

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

[tex]p[/tex] represent the real population proportion of interest

[tex]\hat p=0.07[/tex] represent the estimated proportion for the sample

n=370 is the sample size required (variable of interest)

[tex]z[/tex] represent the critical value for the margin of error

The population proportion have the following distribution  

[tex]p \sim N(p,\sqrt{\frac{\hat p(1-\hat p)}{n}})[/tex]  

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by [tex]\alpha=1-0.90=0.10[/tex] and [tex]\alpha/2 =0.05[/tex]. And the critical value would be given by:  

[tex]z_{\alpha/2}=-1.64, z_{1-\alpha/2}=1.64[/tex]  

The margin of error for the proportion interval is given by this formula:  

[tex] ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}[/tex] (a)  

And replacing into formula (a) the values provided we got:

[tex] ME=1.64\sqrt{\frac{0.07(1-0.07)}{370}}=0.0218[/tex]

The margin of error on this case would be ME=0.0218

Explanation:

Given, sec square 55 – tan squared 55

We know that,

And,

[tex]\tan \theta=\frac{\text { perpendicular }}{\text { base }}[/tex]

where Ө is the angle

Substituting the values

Solving,

[tex]\frac{(\text {hypotenuse})^{2}-(\text {perpendicular})^{2}}{(\text {base}) *(\text {base})}[/tex]

According to Pythagoras theorem,

[tex]\text { (hypotenuse) }^{2}-\text { (perpendicular) }^{2}=(\text { base })^{2}[/tex]

Putting this in the equation;

squared 55 - tan squared 55 =

[tex]\frac{(\text {hypotenuse})^{2}-(\text {perpendicular})^{2}}{(\text {base}) *(\text {base})}=\frac{(\text {base})^{2}}{(\text {base}) *(\text {base})}=1[/tex]

Therefore, sec squared 55 – tan squared 55 = 1

The value is always 1.

To solve the expression sec²(55°) - tan²(55°), we can use a trigonometric identity. Recall the Pythagorean identity for tangent and secant:

sec²(θ) - tan²(θ) = 1

Using this identity, we substitute θ with 55°:

This simplifies our expression immediately, as the value is always 1 regardless of the angle, as long as the identity holds.

So, sec²(55°) - tan²(55°) = 1.

When n=3 and x=−2  the answer is 11.

Step-by-step explanation:

Given:

Let p (n,x) be the function such that

[tex]p (n,x) = n + 2x^{2}[/tex]

To Find:

p (n,x) = p ( 3, -2) = ?

Solution:

[tex]p (n,x) = n + 2x^{2}[/tex]

Substituting n = 3 and x = -2 we get

[tex]p (3, -2) = 3 + 2(-2)^{2}[/tex]

Negative square gives positive number therefore (-2)²=4

[tex]p (3, -2) = 3 + 2\times 4[/tex]

[tex]p (3, -2) = 3 + 8\\p (3, -2) = 11[/tex]

When n=3 and x=−2  the answer is 11.

Final answer:

When evaluating the expression n+2x^2 with n=3 and x=-2, we substitute the values to get 3 + 2(-2)^2, which simplifies to 3 + 8. The final evaluated expression is 11.

Explanation:

To evaluate the expression n+2x² with given values for n and x, we need to substitute the values into the expression and simplify it.

In this case, n = 3 and x = -2. Substituting these values in, we get:

3 + 2(-2)²

First, we calculate the square of -2:

3 + 2(4)

Now, we multiply 2 by 4:

3 + 8

Finally, we add 3 and 8 together:

11

Therefore, the evaluated expression is 11.

Final answer:

To solve the inequality -4x > -24, divide both sides by -4 and flip the inequality sign to obtain x < 6. The solution in interval notation is (-∞, 6).

Explanation:

To solve the inequality -4x > -24, we can divide both sides of the inequality by -4. Remember, when dividing or multiplying both sides of an inequality by a negative number, the inequality sign flips. So, the inequality becomes:

x < 6

The solution in interval notation is (-∞, 6).

Final answer:

The solution is x < 6, which is represented as (-∞, 6) in interval notation.

Explanation:

To solve the inequality -4x > -24, we can start by dividing both sides by -4.

Divide both sides of the inequality by -4. Remember that when you multiply or divide both sides of an inequality by a negative number, the direction of the inequality sign changes.

However, when dividing an inequality by a negative number, the direction of the inequality sign must be flipped. So we have x < 6.

Since the inequality sign is less than, the solution set is all values of x that are less than 6. In interval notation, this is represented as (-∞, 6).

Answer:

1st angle 30°

2nd angle 120°

3rd angle 30°

Step-by-step explanation:

Let's call

A = 1st angle

B = 2nd angle

C = 3rd angle

In every triangle it holds

A + B + C = 180°

Now, if the third angle of the triangle is the same size as the first

A = C

If the second angle is 4 times the third

B = 4C

we have then

C + 4C + C = 180° ===> 6C = 180° ===> C = 30°

If C = 30° then A = 30° and B = 120°
