Answer:

56 degrees.

Step-by-step explanation:

It looks to me like they want you to find the original angle A and you need to use a scientific calculator unless you know advanced calculus. The arcsine or sine^-1 of 0.829 is approximately 56 degrees.

Step-by-step explanation:

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

15

The nearest half is between two numbers.

Here, those 2 numbers are 0 and 30. 15 is in-between.

Therefore, the correct answer would be 15.

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

Answer:

x = -20

Step-by-step explanation:

Given equation:

-8.2x = 164

Divide both sides by -8.2:

⇒ -8.2x ÷ -8.2 = 164 ÷ -8.2

⇒ x = -20

[tex]\\ \rm\rightarrowtail -8.2x=164[/tex]

[tex]\\ \rm\rightarrowtail 8.2x=-164[/tex]

[tex]\\ \rm\rightarrowtail x=-164/8.2[/tex]

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

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

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

The percent error of Shirley's estimate is 21.74%

Answer: 1661 cm^2

Step-by-step explanation:

The area of a circle is pi*radius^2.

The diameter is given as 46 cm and the radius is 1/2 of the diameter = 23 cm.

Therefore, the area of the circle is pi*23^2 = 529pi = about 1661 cm^2

========================================================

Explanation:

The diameter is 46 cm, which cuts in half to the radius of 23 cm.

area = pi*(radius)^2

A = pi*r^2

A = pi*23^2

A = pi*529

A = 529pi

This is the exact area in terms of pi.

--------

From here, replace pi with an approximation such as 3.14

529*pi = 529*3.14 = 1661.06

This value is approximate of course. To get a better approximation, use more decimal digits of pi.

This then rounds to 1661 square cm.

Therefore, the answer is 7. May vary if you assign different values to x.

This should be the answer. if not, then i am confused.
