A farmer had 3,000 acres of land. He planted 30% of it with wheat, 45% of it with corn, and the rest with oats.
Find how many acres he planted with each kind of grain

Answer:

$418

$498

Step-by-step explanation:

Jordan has - 3 * $100 = $300,

                     4 * $20 = $80,

                     1 * $ 10 = $10,

                     8 * $1 = $8

Total =              $398

Jordan’s total will be $418 if Jayla gives him one more $20 bill?

Jordan’s total will be $498 if Jayla gives him one more $100 bill?

Jordan's total will be $438 if Jayla gives him one more $20 bill.

Jordan's total will be $498 if Jayla gives him one more $100 bill.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If Jayla gives Jordan one more $20 bill, then Jordan will have:

3 x $100 = $300

5 x $20 = $100

1 x $10 = $10

8 x $1 = $8

1 x $20 = $20

Adding these up gives:

$300 + $100 + $10 + $8 + $20 = $438

Jordan's total will be $438 if Jayla gives him one more $20 bill.

If Jayla gives Jordan one more $100 bill instead, then Jordan will have:

4 x $100 = $400

4 x $20 = $80

1 x $10 = $10

8 x $1 = $8

Adding these up gives

$400 + $80 + $10 + $8 = $498

Therefore,

Jordan's total will be $438 if Jayla gives him one more $20 bill.

Jordan's total will be $498 if Jayla gives him one more $100 bill.

The correct option is;

R0, 180°

Step-by-step explanation:

The coordinates of ΔXYZ are given as follows;

X(-2, 2), Y(1, 2), Z(0, 4)

The coordinates of ΔX'Y'Z' are given as follows;

X'(2, -2), Y'(-1, -1), Z'(0, -4)

Whereby, the coordinates of the point Y' is (-1, -2), we have the rule that describe the transformation of ΔXYZ to ΔX'Y'Z', given as follows

Coordinates of the preimage = (x, y)

Coordinates of the image = (-x, -y)

Which is in accordance with the transformation by rotation 180° about the origin.

Answer:

x =± 4

Step-by-step explanation:

Solve for x:

x^2 - 16 = 0

The left hand side factors into a product with two terms:

(x - 4) (x + 4) = 0

Split into two equations:

x - 4 = 0 or x + 4 = 0

Add 4 to both sides:

x = 4 or x + 4 = 0

Subtract 4 from both sides:

Answer: x =± 4

Answer: (x + 3) / (x - 2)(x - 3)(x - 4)

Step-by-step explanation:

The problem given can be viewed as

a/b over c/d

where a/b is the top fraction and c/d is the bottom fraction.

This can be rearranged to

a × d / b × c

So, you will have:

(x + 4)(x + 3) / (x² - 5x + 6)(x² - 16)

Now, factor the two bottom polynomials so you end up with:

(x + 4)(x + 3) / (x - 2)(x - 3)(x + 4)(x - 4)

Cancel the (x + 4) on the top and bottom so you’re left with the answer:

(x + 3) / (x - 2)(x - 3)(x - 4)

If you need to find the solutions to x, set the denominator equal to zero.

x = 2

x = 3

x = 4

The selling price of the DVD that has a cost of 15 dollars is 19 dollars and 50 cents.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

A store owner paid $15 for a DVD.

He marked up the price of the DVD by 30%.

The cost price is $15.

Then the selling price will be given as

Selling price = 15 × 1.3

Selling price = $19.50

Answer:

400

Step-by-step explanation:

Let the number be known as "x".

Given statement:

45% of a number is 180.

The term "of" defines multiplication between two terms. In this case, the terms are 45% and the number "x". Therefore,

     ⇒ 45% × x = 180

When we convert a percentage into a fraction, simply divide the percentage by 100 and remove the percentage sign to obtain the result in fraction form.

     ⇒ 45/100 × x = 180

Multiplying 45/100 and x:

     ⇒ 45/100 × x = 180

     ⇒ 45x/100 = 180

Using cross multiplication:

     ⇒ 45x/100 = 180

     ⇒ 45x = 180 × 100

Simplifying the right-hand-side:

     ⇒ 45x = 180 × 100

     ⇒ 45x = 18000

Dividing 45 to both sides of the equation:

     ⇒ 45x = 18000

     ⇒ 45x/45 = 18000/45

     ⇒ x = 18000/45 = 400

Therefore, the number is 400.

Is the simplified form of 2 square root of 3 ⋅ square root of 12 rational?

Simplifying

0 is rational, so the answer is Yes

Answer:

First we need to find a common denominator;

3 1/4 and -5/8 have a common denominator of 8

-5/8 already has 8 now we alter 3 1/4 to have 8 as the denominator as well.

if we make 3 1/4 into an improper fraction we would get 13/4

13/4 x 2/2 = 26/8, because 2 x 4 = 8 so we also apply that to the numerator

Now we have;

26/8 - (-5/8)

the two negatives combine to make a positive:

26/8 + 5/8

= 31/8 which simplifies to

3 7/8

y=-2/7x-61/7

Step-by-step explanation:

convert to slope intercept form

2x+7y=9

7y=-2x+9

y=-2/7x+9/7

slope is -2/7

-7-2/7=-51/7

y=-2/7x-61/7

Answer:

[tex]y=-\frac{2}{7}x-\frac{51}{7}[/tex]

Step-by-step explanation:

Hi there!

We are given the line 2x+7y=9

We want to find the equation of the line that contains the point (-1, -7), and that is parallel to the equation above

Parallel lines have the same slopes.

So we need to find the slope of 2x+7y=9

One way to do this is to convert 2x+7y=9, which is currently in standard form (ax+by=c) into slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept.

In slope-intercept form, y is isolated by itself, so let's start by moving 2x to the other side (it removes it from the left side)

2x+7y=9
-2x      -2x

____________
7y=-2x+9

Now divide both sides by 7

[tex]y=-\frac{2}{7} x + \frac{9}{7}[/tex]

in this equation, -2/7 is in the place of where m should be. This means that -2/7 is the slope of this line.

It is also the slope of the line parallel to it.

The instructions want us to write this equation in slope-intercept form, so let's plug -2/7 as m into the formula.

Here is the equation of the line so far:

[tex]y=-\frac{2}{7}x + b[/tex]

Now we need to find b.

As the equation contains the point (-1, -7), we can use it to help solve for b.

Substitute -1 as x and -7 as y into the equation

[tex]-7=-\frac{2}{7}(-1) + b[/tex]

Multiply

[tex]-7=\frac{2}{7} + b[/tex]

Subtract 2/7 from both sides

[tex]-\frac{51}{7} = b[/tex]

Substitute -51/7 as b in the equation

[tex]y=-\frac{2}{7}x-\frac{51}{7}[/tex]

Step-by-step explanation:

Given:

Total number of flower they buy = 29 stems

Total cost = $120.94

Lilies cost = $3.42 per stem

Peonies cost = $4.78 per stem

To find:

The number of lily stems and peony stems did they buy.

Solution:

Let number of lily stems = x

Number of lily stems and peony stems = y

According to given information,

[tex]x+y=29[/tex]                           ...(i)

[tex]3.42x+4.78y=120.94[/tex]                ...(ii)

From (i) and (ii), we get

[tex]3.42x+4.78(29-x)=120.94[/tex]

[tex]3.42x+138.62-4.78x=120.94[/tex]

[tex]-1.36x=120.94-138.62[/tex]

[tex]-1.36x=-17.68[/tex]

Divide both sides by -1.36.

[tex]x=\dfrac{-17.68}{-1.36}[/tex]

[tex]x=13[/tex]

Put x=13 in (i).

[tex]13+y=29[/tex]

[tex]y=29-13[/tex]

[tex]y=16[/tex]

Therefore, number of lily stems is 13 and number of lily stems and peony stems is 16.

Answer:

kpm is about 110.02 degrees

Step-by-step explanation:

-kpl and npm are vertical angles, so they're congruent

-npm and lpm are supplementary angles, meaning they add to 180 degrees

we r given:

npm = 14x - 22

lpm = 7x + 4

add these and set equal to 180:

14x - 22 + 7x + 4 = 180

then combine like terms:

21x -18 = 180

isolate the variable by adding 18 on both sides:

21x = 198

divide by 21 on both sides:

x = about 9.43

since kpl and npm r congruent, plug in the value of x in npm (14x-22):

14(9.43)-22

= 110.02
