Crop yield is the ratio of the number of bushels harvested to the number of acres used for the harvest. This year, the harvest at a farm was 9,396 bushels of soybeans, resulting in a crop yield of 40.5 bushels per acre.

To the nearest whole acre, how many acres were harvested?

232 acres
252 acres
285 acres
295 acres

Answers

Answer:

A. 232 acres

Step-by-step explanation:

Got it right

The number of acres of land that were harvested is given by A = 232 acres

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the total amount of harvest of bushels be = 9,396 bushels

And , the amount of bushels per acre = 40.5

So , number of acres of land that were harvested is A = amount of harvest of bushels / amount of bushels per acre

On simplifying the equation , we get

The number of acres of land that were harvested is A = 9,396 / 40.5

The number of acres of land that were harvested is A = 232 acres

Hence , the number of acres is 232 acres

Race car driver traveled at an average speed of 120 miles per hour to finish a race in 2 hours. What is the length of the race?

Answers

Answer:

240

Step-by-step explanation:

If you are going 120 mph for 2 hours.  You simply multiply the two values, giving 240 and the units for this is miles because in the multiplication, the units are m/h * h and this cancels out the hours and leaves just miles.

Answer:

240miles

Step-by-step explanation: 120 per hour X 2 hours = 240

abc = 53

Answer:

Option A

Step-by-step explanation:

Hey there!

From the given figure;

Angle ABE = 90°.

And angle ABD = [(5x+3)° +(3x+7)°]

To find : angle ABC.

Now,

Angle ABD + Angle ABE = 180° [Being linear pair].

or, 90° + [(5x+3)° +(3x+7)°]= 180°

or, (5x+3)° +(3x+7)°= 90°

or, 8x + 10° = 90°

or, 8x = 80°

Therefore, X= 10°.

Now, Angle ABC = (5x + 3)°

= (5*10+3)°

= 53°

Therefore, the measure of angle ABC is 53°.

Hope it helps!

How do i know when to use Sine, Cos or Tan? i struggle so much :c

Answers

Answer:

Sin = If you have hypotenuse and the opposite side

[tex]\frac{opp}{hyp}[/tex]

Cos = If you have hypotenuse and an adjacent(close by) side

[tex]\frac{adj}{hyp}[/tex]

Tan = If you have the adjacent and opposite sides

[tex]\frac{opp}{adj}[/tex]

Answer with step-by-step explanation:

Hi there! The Sine, Cosine, and Tangent functions have many different uses and there are various circumstances where you can use them. They are generally used for trigonometry.

Let's start with basic trigonometry for a right triangle. This is likely where these functions were introduced to you.

For any right triangle:

The sine of an angle is equal to its opposite side divided by the hypotenuse of the triangle (o/h).

The cosine of an angle is equal to its adjacent side divided by the hypotenuse of the triangle (a/h).

The tangent of an angle is equal to its opposite side divided by its adjacent side (o/a).

Any angle's "opposite" side is defined by the side the angle creates or is opposite to the opening of the angle. The adjacent side of an angle is defined by the side that touches/forms the angle that is not the hypotenuse. The hypotenuse is always defined as the longest side of a right triangle.

Oftentimes, students used the phrase "SOH-CAH-TOA" to remember this. The abbreviation simply stands for "Sin-Opposite-Hypotenuse || Cos-Adjacent-Hypotenuse || Tan-Opposite-Adjacent". Regardless of how you remember it, it is crucial to note that this only works for a right triangle.

These are just the basics, but you'll work with sine, cosine, and tangent as you learn about the Unit Circle, Law of Sines, Law of Cosines, sinusoidal functions, the graphs they make, and more.

Determine whether each function is even, odd, or neither. g(x) = |x-3| neither g(x) = x + x² neither

Answers

Answer:

So, both the functions are neither even and nor odd.

Step-by-step explanation:

A function is even if g(x) = g(-x) and odd if g(x) = - g(x).

g(x) = |x-3|

g (-x ) = | -x -3 |

So, the function is neither even and nor odd.

g (x) = x + x²

g (- x) = (- x) + (- x) ² = -  x + x²

So, the function is neither even and nor odd.

m∠1 = 147°

Step-by-step explanation:

(5x-2)° and ∠1 are supplementary to each other, which means they add up to 180°. However, we don't know the measure of ∠1. So, we need to solve for x to figure out angle (5x-2)°'s measure. Therefore:

(8x+1)°+(5x-2)°+90°=180°

8x+1+5x-2+90=180

13x+89=180

13x=91

x=7

This means the measure of angle (5x-2)° is 33°, making the measure of ∠1 equal to 147°.

In this rectangular prism, these sides are:

[tex]\begin{aligned}& 2 \times 40\; \rm ft^{2} + 2 \times 150\; \rm ft^{2} + 2 \times 240\; \rm ft^{2} = 860\; \rm ft^{2}\end{aligned}[/tex].

Find the sixth term of the geometric sequence 9, -27, 81,
a6

Answers

Answer:

The sixth term of the sequence = -234

Step-by-step explanation:

The formula of a geometric sequence is:

aₙ = a₁ + r⁽ⁿ⁻¹⁾

Where;

aₙ = the term value

n = the term that has to be found out

a₁ = first term in the sequence

r = common ration

Here in this situation:

aₙ = unknown

n = 6

a₁ = 9

r = -3

Therefore the solution would be:

a₆ = 9 + (-3)⁶⁻¹

a₆ = 9 + (-3)⁵

a₆ = 9 + (-243)

a₆ = -234

Therefore the sixth term of the sequence would be: -234
