A farmer divides a rectangular piece of land with a perimeter of 140 yards into two triangular parts as shown in the diagram. If the area of ABC is 600 square yards, what is the area of ACD? A. 880 square yards B. 740 square yards C. 600 square yards D. 460 square yards

Answer:(-4,1)

Step-by-step explanation:x values cannot be the same

Answer:

L = 2500/W

Step-by-step explanation:

Let the fields m be rectangular in nature

Area = LW

Perimeter = 2(L+W)

L is the length

W is the width

Given

Perimeter = 200ft

Area = 2500ft²

Substitute into the formula

200 = 2L+2W

100 = L+W ...... 1

2500 = LW.... 2

From 1; L = 100-W

Substitute into 2

2500 = (100-W)W

100W - W² = 2500

W²-100W+2500 = 0

W²-50W-50W+2500 = 0

W(W-50)-50(W-50) = 0

W - 50 = 0

W =50

Substitute w = 50 into LW = 2500

L = 2500/50

L = 50

Hence the equation that can be used to find the length of the field is

L = 2500/W

Answer:

The answer is $668.00

Step-by-step explanation:

Just add 200 to how much you will pay over time. So first multiply 39 by 12 (12 months in a year, 39 per month,) to find out how much you will pay by the end of the year then add 200 to that.

Answer:

It's 60

Step-by-step explanation:

All triangles angles have to add up to 180 degrees. 60 plus 60 plus 60 is `80.

Answer:

C. 120°

Step-by-step explanation:

Just by looking at it, you can see that it is over 90° which automatically makes it not 60° and your only option left is 120°

Answer:

The answer is given below <3

Step-by-step explanation:

The options are not given but I would list the inequalities needed to solve this problem.

As a result of increase in people to attend meeting, the number of sushi needed to be ordered is 100 pieces. Sofia has already ordered 24 pieces. If R is the number of additional rolls that Sofia orders.

The number of additional rolls that Sofia orders (R) must be greater than or equal to the difference between the number of Sushi needed to be ordered and the number of Sushi that has already being ordered. It is given by the inequality:

R ≥ 100 - 24

R ≥ 76

If each roll contains 12 pieces, the number of rolls needed (n) is given by:

n ≥ R/12

n ≥ 76/12

n ≥ 6.33

n ≥ 7

If each roll cost $8, the money needed to buy the sushi is given as:

Cost ≥ 8(7) ≥ $56

Answer:

x-intercept:8

y-intercept:16

Step-by-step explanation:

This is the equation of a straight line. When the line crosses the x-axis that is the x- intercept, the corresponding y-coordinate will be zero. Substituting y = 0 into the equation and solving for x gives the x-intercept.

8x-(4×0)=-64

         -8x=-64

             x=8   <=  the x-intercept.

Similarly, when the line crosses the y-axis the corresponding x- coordinate will be zero. Let x = 0 and solve for y.

(8×0)-4y=-64

        -4y=-64

           y=16    <=  the y-intercept .

Answer:

x = 1/2

y = -8

Step-by-step explanation:

Let's solve for x.

8x−4y=−64

Step 1: Add 4y to both sides.

8x−4y+4y=−64+4y

8x=4y−64

Step 2: Divide both sides by 8.

8x/8 = 4y−64 / 8

x= 1/2 y−8

18 + 5x

Answer:

Michelle

Step-by-step explanation:

Given the data:

S Name No of Pop Albums Total No of Albums Michelle 33 60

Sasha 36 78

Kat 40 89

Monica 24 59

Percentage of pop Albums:

(Number of pop album / total number of albums) * 100%

Michelle :

(33 /60) * 100% = 55%

Shasha:

(36 /78) * 100% = 46.15%

Kat:

(40 / 89) * 100% = 44.94%

Monica :

(24 / 59) * 100% = 40.67%

Hence, Michelle has the greatest percentage of pop Albums

Answer:

The length of AD is 70

Step-by-step explanation:

From the given figure

→ In triangle ADC

∵ EB // to DC

→ That means EB divides the sides AD and AC into parts proportional

∴ E divides AD into AE and ED

∴ B divides AC into AB and BC

∴ [tex]\frac{AE}{ED}[/tex] = [tex]\frac{AB}{BC}[/tex]

∵ ED = 60

∵ AB = 12

∵ BC = 72

→ Substitute them in the ratio above

∴ [tex]\frac{AE}{60}[/tex] = [tex]\frac{12}{72}[/tex]

→ By using cross multiplication

∵ AE × 72 = 12 × 60

∴ 72 AE = 720

→ Divide both sides by 72

∴ AE = 10

∵ AD = AE + ED

∴ AD = 10 + 60

∴ AD = 70

∴ The length of AD is 70

Answer:

D is right

Step-by-step explanation:

The true statement about 3/5+7/10 is (a) the sum is a mixed number

The expression is given as:

3/5 + 7/10

Take the LCM and add both numbers

3/5 + 7/10 = (6 + 7)/10

Evaluate the sum

3/5 + 7/10 = 13/10

Simplify

3/5 + 7/10 = 1 3/10

The fraction 1 3/10 is a mixed number

Hence, the true statement about 3/5+7/10 is (a) the sum is a mixed number

Donald can type 240 words in 6 minutes. How long will it take him to type a 1000-word essay if he types at the same rate?

This question can be solved by using proportions. The question has already given a proportion you need to fill in, which looks like this:

[tex]\displaystyle \frac{A}{B} =\frac{x}{1000}[/tex]

As you can see, the denominators are B and 1000, which represents the number of words. That means the number of words will go on the bottom, which leaves you with the number of minutes as the numerator.

Donald can type 240 words in 6 minutes. The number of words, 240, is the denominator, and the number of minutes, 6, is the numerator.

Substitute A and B with these values:

[tex]\displaystyle \frac{A}{B} =\frac{x}{1000} \rightarrow \frac{6}{240} =\frac{x}{1000}[/tex]

Now you need to cross multiply.

[tex]1000 \times 6=240 \times x[/tex]

Simplify:

[tex]6000=240x[/tex]

Lastly, you need to divide both sides by 240 to find the value of x alone. This is because 240 is being multiplied by x, and in order to leave x alone, you must do the opposite of it, which is dividing.

[tex]\displaystyle \frac{6000}{240} =\frac{240x}{240}[/tex]

[tex]\displaystyle x=25[/tex]

That means Donald can type 1000 words in 25 minutes. A is also equal to 6, and b is equal to 240.

__________________________________________________________

[tex]\displaystyle {\bf\frac{6}{240} =\frac{x}{1000}[/tex]

Solving this proportion indicates Donald could type his essay in 25 minutes.

Answer:

d:$167,00

Step-by-step explanation:

Answer:

x = 1, y = 2

Step-by-step explanation:

Original equations:

[tex]x+y=3\\2x+5y=12[/tex]

Substitute y and solve for x:

[tex]y=3-x\\2x+5y=12[/tex]

[tex]2x+5(3-x)=12[/tex]

[tex]2x+15-5x=12[/tex]

[tex]-3x=-3[/tex]

[tex]x=1[/tex]

Plug in x to solve for y:

[tex]1+y=3[/tex]

[tex]y=2[/tex]

x = 1, y = 2

Note: You can also substitute x and solve for y, then plug in y to solve for x. I did not do that here.

Answer:

x+y=3

x=3-y equation 1

2x+5y=12

2(3-y)+5y=12

6-2y+5y=12

6+3y=12

3y=12-6

y=6÷3

y=2 equation 2

again ,

putting value of equation 2 in equation 1

x=3-y

x=3-2

x=1
