The new width of the photo is 2 inches.

To find the new width of the photo, we can use the concept of proportions. Let's set up the proportion:

Original Height / Original Width = Reduced Height / New Width

Plugging in the given values, we have:

16 in / 8 in = 4 in / x

Cross multiplying, we get:

16x = 32

Dividing both sides by 16, we find:

x = 2

So the new width of the photo is 2 inches.

Final answer:

Fifth graders take up 96 seats, leaving 82 fourth graders. Dividing 82 by 8 seats per row yields 10.25, which we round up to 11 rows needed for the fourth graders.

Explanation:

To calculate the number of rows needed for the fourth graders, we need to first determine the total number of seats taken by the fifth graders. Since each row has 8 seats and the fifth graders fill 12 rows, the total number of seats taken by the fifth graders is 12 rows × 8 seats/row = 96 seats.

Now, we subtract the number of seats taken by the fifth graders from the total number of students attending to find out how many fourth graders there are: 178 students - 96 seats taken by fifth graders = 82 fourth graders.

The number of rows needed for the fourth graders can be calculated by dividing the total number of fourth graders by the number of seats per row: 82 fourth graders ÷ 8 seats/row = 10.25 rows. Since we can't have a fraction of a row, we round up to the next whole number. Therefore, the fourth graders will need 11 rows.

Answer:

The area of figure is 304 square unit.

Step-by-step explanation:

The figure divided into 2 equal trapezoids.The height of each is 8. The basis of each trapezoid are 14 and 24. It means the length of the parallel sides are 14 and 24.

Area of a trapezoid is

[tex]A=\frac{a+b}{2}\cdot h[/tex]

Where, a and b are length of parallel sides and h is the height of trapezoid.

Area of a trapezoid is

[tex]A_1=\frac{24+14}{2}\times 8[/tex]

[tex]A_1=19\times 8[/tex]

[tex]A_1=152[/tex]

Therefore area of a trapezoid is 152.

The area of figure is twice of area of a trapezoid.

[tex]A=2\times A_1=2\times 152=304[/tex]

Therefore the area of figure is 304 square unit.

xᵇ-12 + xᵇ= 98

2xᵇ-12= 98

2xᵇ=98+12=110

xᵇ=110/2=55

xᵇ=55

xᵃ=xᵇ-12

xᵃ=43

Final answer:

The weekly take-home pay from a $45,000 annual salary with a 22% total tax burden is approximately $675.00 after taxes.

Explanation:

To calculate the take-home pay from a paycheck when you know the annual salary and the total tax rate, you must first determine the amount of money deducted for taxes and then subtract that from the gross (before-tax) pay. If a job pays $45,000 per year and the total tax burden is 22%, we can find the annual take-home salary and then divide by the number of pay periods per year to get the weekly take-home pay.

First, calculate the total annual taxes: $45,000 * 0.22 = $9,900.

Next, subtract the annual taxes from the annual salary to get the annual take-home salary: $45,000 - $9,900 = $35,100.

Since there are 52 weeks in a year, divide the annual take-home salary by 52 to find the weekly take-home pay: $35,100 / 52 \\approx $675.00.

Therefore, the weekly take-home pay would be approximately $675.00.

To find the axis of symmetry.

A quadratic equation is in the form of :

[tex]ax^2+bx+c =0[/tex] where a, b and c are coefficients and x is the variable

Axis of symmetry is given by :

[tex]x = -\frac{b}{2a}[/tex]

First identify a, b and c in the equation

[tex]f(x) = 3x^2[/tex]

⇒ a= 3 , b= 0 and c =0

[tex]g(x) = x^2-4x+5[/tex]

Answer:

The correct option is D.

Step-by-step explanation:

It is given that

[tex]\sin \theta =\frac{-77}{85}[/tex]

[tex]\cos \theta =\frac{36}{85}[/tex]

The angle of terminal ray is θ, it means the angle between x-axis and terminal ray is θ.

[tex]\sin \theta =\frac{perpendicular}{hypotenuse}[/tex]

[tex]\cos \theta =\frac{base}{hypotenuse}[/tex]

Therefore the length of perpendicular is 77 and the base of the triangle is 36.

Since sinθ is negative and cosθ is positive, it means point must be lies on fourth quadrant because in fourth quadrant cosine in positive but sine is negative.

The point of terminal ray is (base, perpendicular) and the sign are used according to the quadrant.

Therefore the point of terminal ray is (36,-77) because in fourth quadrant x is positive but y is negative. Option D is correct.

The coordinates of the point (x, y) on the terminal ray of angle theta are (36, -77).

Given

Three trigonometric functions for a given angle are shown below.

sin theta = -77/85, cos theta=36/85, tan theta=77/36.

A ray is defined as the initial side of the angle.

Answer: Rational numbers are any numbers that can be expressed by a fraction with integers in both the numerator and the denominator. The amount of time and paper it takes to put them into an increasing line depends on how many numbers there are and how big of a range they have.

1.Rewrite improper fractions

An improper fraction is a fraction with a bigger numerator than denominator. These numbers can be difficult to compare. For example, numbers such as 26/7, 31/9, 12/5, 8/3 and 22/13 do not have an obvious highest or lowest term. Rewrite improper fractions as mixed numbers or as numbers with decimals. To turn an improper fraction into a decimal, divide the numerator by the denominator. If the denominator is large or a prime number greater than five, use a calculator. For example, divide the numbers 26/7, 31/9, 12/5, 8/3 and 22/13 to create 3.71, 3.44, 2.4, 2.67 and 1.69.

2.Find the highest and lowest terms

Figure out where your number line starts and ends. Put the lowest term on the far left and the highest term on the far right. Remember, negative numbers are lower than positive numbers, and the greater a negative number's distance from zero, the lower it is.

3.Mark benchmark terms

Draw a line extending through your lowest and highest points. Figure out some major points between these values and mark them on your line. For example, if your lowest number is negative 25 and your highest number is 50, find where zero and 25 would be. Mark these as benchmarks or guides.

4.Fill in the remaining numbers

Using your guides, fill in the rest of the numbers. Start with the lowest values on the left and work your way up.  

Rational and irrational numbers can be ordered from least to greatest by converting them into decimal forms. Once in decimal form, they can be compared and ordered just like regular real numbers.

To order rational and irrational numbers from least to greatest, first you need to understand what these numbers are. Rational numbers are numbers that can be expressed as a ratio of two integers, while irrational numbers cannot be expressed as such ratio and their decimal expansions are non-repeating and non-terminating.

If you are given both rational and irrational numbers, you can start by converting all of the numbers to decimal form if they are not already. Then, you can simply order them from least to greatest, just like how you order regular real numbers.

For example, if you are given the numbers 3/2, √2, and 1. You would convert 3/2 to 1.5 and approximate √2 as 1.414. Then you would order them as 1 (1.0), √2 (1.414), and 3/2 (1.5).
