Julio has 200 ft of fencing to put around a field that has an area of 2500 sq ft. Write an equation that can be used to find the length of
the field?
Answers
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

find the x- and y-intercepts of the line with equation 8x - 4y = -64
Answers
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

Solve the equations by substitution method: A) x+y=3, 2x+5y=12.
Answers
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

My explanation is because the angle is gives you is 62, and all of those are technically 90 degree angles that when all are added up they become 360 for the whole thing. 90-62=28, but you don’t need that angle. So my guess is that the angle with 62 degrees is going to be the same as the angles you are looking for.

Michelle :
(33 /60) * 100% = 55%
Shasha:
(36 /78) * 100% = 46.15%
Kat:
(40 / 89) * 100% = 44.94%
Monica :

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?
Fill in the blanks with the correct values.
Answers
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.

a gym is offeringa deal to new members. Customers can sign up by paying a registration fee of $200 and a monthly fee of $39. How much will this membership cost a member by the end of one year?
Answers
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.
explanation: there is 12 months in a year, so if you make an equation it would be, 200+39x, input 12 for x making it 200+39(12) 39(12)=468, now you need to add the fee of $200 to 468 making the cost of the membership after one year $668.

Sofia ordered sushi for a company meeting. They change plans and increase how many people will be at the meeting, so they need at least 100 pieces of sushi in total.
Sofia had already ordered and paid for 24 pieces of sushi, so she needs to order additional sushi. The sushi comes in rolls, and each roll contains 12 pieces and costs $8.
Let R represent the number of additional rolls that Sofia orders.
1) Which inequality describes this scenario?
Choose 1 answer:
A) 12 + 24R ≤ 100
B) 12 + 24R ≥ 100
C) 24 + 12R ≤ 100
D) 24 + 12R ≥ 100
2) What is the least amount of additional money Sofia can spend to get the sushi they need?
dollars
Answers
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

Answers
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
