Marco needs $57 to buy new basketball shoes. If Marco earns $3 per day working and already has $12 saved, which equation shows how many days Marco must work before he can afford the shoes?
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.

What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation be represented as A
Now , the value of A is
The initial amount in Justin's savings account = $ 4
The amount saved by Justin every week = $ 2
Let the number of weeks be = x
So , the amount saved by Justin in x weeks = 2x
Now , the total amount saved by Justin in savings account A = initial amount in Justin's savings account + amount saved by Justin in x weeks
Substituting the values in the equation , we get
A = 4 + 2x
On simplifying the equation , we get
A = 2x + 4

sec squared 55 - tan squared 55
Answer:
sec squared 55 – tan squared 55 = 1
Explanation:
Given, sec square 55 – tan squared 55
We know that,
[tex]\sec \Theta=\frac{\text {hypotenuse}}{\text {base}}[/tex]
And,
[tex]\tan \theta=\frac{\text { perpendicular }}{\text { base }}[/tex]
where Ө is the angle
Substituting the values
[tex]\left(\frac{\text {hypotenuse}}{\text {base}}\right)^{2}-\left(\frac{\text { perpendicular }}{\text {base}}\right)^{2}[/tex]
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°:
sec²(55°) - tan²(55°) = 1This 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.

Estimate the size of a crowd walking in a charity fundraising march that occupies a rectangular space with dimensions of 10 feet by 1,200 feet (to the nearest whole number). Assume that 40 people occupy a rectangle measuring 10 feet by 12 feet.
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.

Solve the inequality $-4x > -24.$ Give your answer in interval notation.
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).
50 points! A polynomial has been factored below, but some constants are missing. 2x^3 - 8x^2 - 24x = ax (x+b)(x+c) What are the missing values of a, b, and c?
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]

y+1=4(x+3)
y−1=4(x−3)
y+3=4(x+1)
y−3=4(x−1)
Answer:
y + 3 = 4(x + 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 4 and (a, b) = (- 1, - 3), thus
y - (- 3) = 4(x - (- 1)), that is
y + 3 = 4(x + 1)

Dylan plants grass in a rectangular space behind the clubhouse.the area of the space is 70 square feet. If the length of the space is 14 feet . what is the width of the space
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.
x^(logx) = 1000000x
Find x.
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,

In a recent poll, 370 people were asked if they liked dogs, and 7% said they did. Find the margin of error of this poll, at the 90% confidence level. Give your answer to three decimals.
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

Find the lateral area and surface area of the solid. Use the 2.5 by 2.5 square as the base. Round to the nearest tenth if necessary.
I am unable to add a photo, the base is: 5.5ft, 5.5ft, and the height is 10ft.
Choices:
L = 220ft2 ; S = 302.5 ft2
L = 280.5 ft 2 ; S = 220ft2
L = 170.5 ft2 ; S = 280.5ft2
L = 220ft 2 ; S = 280.5 ft2
Answer:
Part 1) [tex]LA=220\ ft^2[/tex]
Part 2) [tex]SA=280.5\ ft^2[/tex]
L = 220 ft2 ; S = 280.5 ft2
Step-by-step explanation:
The correct question is
Find the lateral area and surface area of a rectangular prism. The base is a square 5.5 ft by 5.5 ft, and the height is 10 ft
Part 1) Find the lateral area
The lateral area of a rectangular prism is equal to
[tex]LA=Ph[/tex]
where
P is the perimeter of the base
h is the height of the prism
we have
[tex]P=4(5.5)=22\ ft[/tex] ---> the perimeter of a square
[tex]h=10\ ft[/tex] ---> is given
substitute
[tex]LA=22(10)=220\ ft^2[/tex]
Part 2) Find the surface area
The surface area of a rectangular prism is equal to
[tex]SA=2B+LA[/tex]
where
LA is the lateral area
B is the area of the base
we have
[tex]LA=220\ ft^2[/tex]
[tex]B=5.5^2=30.25\ ft^2[/tex] ----> area of a square
substitute
[tex]SA=2(30.25)+220=280.5\ ft^2[/tex]
Answer:
D. L = 220 ; S = 280.5
