Answer:
648 sq. ft.
Step-by-step explanation:
The ratio 2:9 can be modified, as any ratio can, as long as you multiply/divide the two sides by the same amount
If you need to find how much the 4-inch side is in ft., you can multiply both sides of the ratio by 2, since 2 x 2 is 4.
2:9 is the same as:
2 x 2: 9 x 2
4in : 18ft
18 ft. is the measurement of the first side
2:9 is also the same as:
2 x 4: 9 x 4
8in:36ft
36 ft. is the measurement of the second side
Multiply the two sides (width x length = area) to get the area of the park
18 x 36
= 648

Dilate the triangle by a factor of 2 about the origin.
Answer:
the dilate is when you multiply the prime by the coefficient and the coefficient in this problem is -3 so -3x1=3
Step-by-step explanation:
Given the vectors v=3i-2j and w=-i+5j, find v · w.
v * w = (3i - 2j) *(-i + 5j) = 3(-1) + (-2)(5) = -3 + -10 = -13
Hope that helps!
Answer:
v.w = -13
Step-by-step explanation:
v.w = (3i - 2j).(-i + 5j) = 3 × -1 × i.i + 3 × 5 × i.j + -2×-1 × j.i + -2×5 × j.j
i.i = j.j = 1 , i.j = j.i = 0
→
v.w = -3 - 10 = -13

Part A . If i sell 2 skeins for 5 dollars what is the cost per skin of yarn
Part B. I need 6 skeins of yarn to make an afghan. How much will the yarn cost
Answer: Part A = $2.50, Part B. $15.00
Step-by-step explanation:
Part A. Since 2 skeins of yarn cost 5 dollars, that means each skein must cost 5/2 dollars = $2.50
Part B. Since we know each skein costs $2.50, 6 skeins of yarn would cost 2.5*6 = $15.00
#2
No of skeins=6
Cost=6(2.5)=15$Pls help it is due very soon.
Answer:
AC = √105 ≈ 10 cm (nearest whole number)
Step-by-step explanation:
Use Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse of a right triangle)
Give one of the legs = 4cm and the hypotenuse = 11 cm:
⇒ 4² + AC² = 11²
⇒ 16 + AC² = 121
⇒ AC² = 121 - 16
⇒ AC² = 105
⇒ AC = ±√105
As distance is positive, length of AC = √105 ≈ 10 cm (nearest whole number)
Step-by-step explanation:
AB²=BC²+CA²
(11)²=(4)²+ CA²
121=16 + CA²
121-16= CA²
105=CA²
√105=CA
10.2=CA

Fractions
Answer:
7/8
Step-by-step explanation:
To add the fractions, find the LCD and then combine.
Answer:
We have to make sure the denominators are equal.
Since 2 is evenly divided by 8, we can multiply just one term to get a common denominator.
Multiply 1 by 4, and get 4, then we multiply 2 by 4 and get 8.
x4
So you multply 1/2 4/8 (muliply numerator)
x4
1/2 x 4/8 (multiply denominator
now 3/8+4/8
since denominators match you can add
3+4=7 so its 7/8
