A farmer has just tilled her 51-yard by 68-yard field. To survey her field, the farmer begins in one corner and walks the length of the field. She then turns and walks the width before crossing diagonally across the field to the original corner. How far does the farmer walk?
Answer: l +w+ hypotenuse or 204
Step-by-step explanation: so the farmer walks the length then the width of the field then the diagonal which we don't know using pythagorean to find that last side then add the values 51^2+68^2=c^2 and 51+68+85= 204

A package designer wants the hexagonal base of a hat box to have an area of
about 200 in.2. About how long is each side?
Answer:
About 9inches long
Step-by-step explanation:
Area of a hexagon = 3√3/2 a²
a is the length of each side
Given
Area of the hexagon = 200in²
Substitute
200 = 3√3/2 a²
200×2 = 3√3 a²
400 = 3√3a²
a² = 400/3√3
a² = 400/5.196
a² = 76.982
a = √76.982
a = 8.774
Hence the length of each side is about 9inches long (to nearest inches)

pls help me with this multiple choice !
Answer:
D
Step-by-step explanation:
[tex] \sin(60) = \frac{ \frac{5 \sqrt{3} }{2} }{a} \\ a = \frac{ \frac{5 \sqrt{3} }{2} }{ \sin(60) } = 5 \\ \cos(60) = \frac{b}{5} \\ b = 2.5 = \frac{5}{2} [/tex]

Answer:28
Step-by-step explanation: 7x4 Equals 28 basketballs
X = 7
Y = 6
Y = 24
X = ?
24/6=4
7x4 = 28
Your answer is 28
What steps would you use to solve this equations for x? *
Answer:
x=-24
Step-by-step explanation:
Multiply both sides by 4 to get x=-24
[tex]\\ \rm\hookrightarrow -6=\dfrac{x}{4}[/tex]
Multiply 4 on both sides
[tex]\\ \rm\hookrightarrow x=-6(4)[/tex]
[tex]\\ \rm\hookrightarrow x=-24[/tex]
Four positive whole numbers add up to 39 one of the numbers are a multiple of 7 the other three are equal workout the result when the four numbers are multiplied
Answer:
Number is 4536
Step-by-step explanation:
Assume;
Same number = a
Multiply of 7 = b
So,
a+a+a+b = 39
3a + b = 39
Use b = 7
3a + b = 39
3a + 7 = 39 (Not possible)
Use b = 14
3a + b = 39
3a + 14 = 39 (Not possible)
Use b = 21
3a + b = 39
3a + 21 = 39
a = 6
So,
Number is 6 x 6 x 6 x 21
Number is 4536

Select the equation and solution for the problem. Let x represent the unknown number.
A total of 15 people on a sports team are riding in 3 vans. How many people are riding in each van if each van is carrying the same number of people?
Answer:
C
Step-by-step explanation:
So your total is 15. There are 3 vans, and we want to know how many are on each van.
3 (number of people on each van)=15
Number of people are unknown
3x=15
Divide both sides by 3 to solve for x
x=5
If you get the answer just give me the full answer please. No matter the length.
Answer:
CD = 4
Step-by-step explanation:
I believe you know the geometric mean for altitudes?
CD = √AD * DB = √8 * 2 = √16 = 4
If you are not aware of this theorem, then use the similarity of triangles.
ADC ~ CDB
AD/DC = CD/DB (cross-multiply)
CD^2 = AD*DB,
CD = √AD * DB = √8 * 2 = √16 = 4
Farid thinks last month was unusually rainy in his town—they had 6 inches of rain! His town's current record for rainfall in a year is 2 feet. Farid wonders what the new record would be if they were to keep getting this much rain for an entire year. If Farid's town had 6 inches of rain every month for 12 straight months, by how many feet would they beat the annual record?
Each square is one square unit. Sienna uses the same square units to draw a 6 x 2 rectangle and says that it has the same area as the 3 x 4 rectangle. Is she correct?
Answer:
Yes, Sienna is correct because 6 times 2 is 12 and 3 times 4 is 12.

Find the value of x so that f(x)=3
Answer:
f(x) = (1/3)x - 2
f(x) = (1/3)(3) - 2
f(x) = 1 - 2 = -1
Step-by-step explanation:
f(x) usually refers to a function not a multiplication of two variables

A ladder is 12 metres long . It leans against a wall with one end on the ground 7 metres from the wall. The other end just reaches a windowsill. Calculate the height of the windowsill above the ground.
i need an explanation please...
Answer:
window sill height =9.75 meters
Step-by-step explanation:
Ladder^2=height^2+length^2
12^2=height^2+7^2
144=height^2+49
height^2=144-49=95
height=9.75
Round 72.178 to the nearest hundredth.
Answer:
72.18
Step-by-step explanation:
The hundreth place is the second to the right of the decimal. So the number in the hundreths place is 72.178. When rounding, you look at the number behind the number you are rounding to. In this case, you want to look at the 8. If the number is 5 or above, you round up. 8 is above 5 so you round the 7 to an 8.
Answer: 72.18
Step-by-step explanation:

2. Emma knows that her mix of 5 cups of orange juice to 2 cups of ginger
ale will create enough drink for 7 people. If she is looking to create
enough drinks for 28 people, how many cups of orange juice will she
need? *
Answer:
11 1 /2 ( 11 and a half)
Step-by-step explanation:
If you noticed 7 and 2 are five numbers away.
To solve this I just added one to both of them until the sum was equal to 28.
If I had added one to 16 and 11, it would have given me 29, so I added a half.
That gave me 28.
Which of the following are point slope form of the line going through (-4,6) and (1,2)
Answer:
answer in comment
Step-by-step explanation:
So, we have to find the slope of the line. We are given two points, so we can use those:
(x1,y1) = (-4,6)
(x2,y2) = (1,2)
m = (y2-y1)/(x2-x1) = (2-6)/(1--4) = (2-6)/(1+4) = -4/5
Also, we know that point-slope is of the form:
(y-y1) = m*(x-x1)
It doesn't matter which point you use, though, you can also use:
(y-y2) = m*(x-x2)
So we can plug the variables into the equation and get:
(y-2) = -4/5*(x-1)
OR
(y-6) = -4/5*(x+4)
