Please help me I really need help with. What is -8.2x = 164 and what does x=
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]
[tex]\\ \rm\rightarrowtail x=-20[/tex]

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

The grocery store is having a candy sale. Originally, a candy bar was $1.50. The
sale price is $0.50. What is the markdown rate? Round to the nearest whole
percent.
The markdown rate is 66.7%.
Markdown rateUsing this formula
Markdown rate= Change in price/original price×100
Let plug in the formula
Markdown rate=$1.50-$0.50/$1.50
Markdown rate=$1.00/$1.50×100
Markdown rate=66.66%
Markdown rate=66.7% (Approximately)

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

Shirley estimated the length of a board to be 18 inches. The actual length is 23 inches. To the nearest tenth of a percent, what is the percent error of Shirley's estimate? Enter your answer as a decimal in the box.
The percent error of Shirley's estimate is 21.74%
Calculating pecent errorGiven the following parameters
Actual length = 23 inchesEstimated length = 18in% error = actual-estimated/actual * 100
% error = 23-18/23 * 100
% error = 500/23
% error = 21.74%

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

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.

Aaron makes a scale drawing of a rectangular park. The scale he uses is 2 in: 9 ft. What is the actual area of the floor of the park if the dimensions on the scale drawing are 4 in by 8 in?
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

A grain silo with the shape of a right cylinder is to be filled with corn. The diameter of the silo is 14 feet and the height is 30 feet. Excluding the domed top, approximately how many cubic feet of corn will the silo hold? Use 3.14 for
π
The cubic feet of corn the cylinder silo will hold is 4615.8 ft³.
Volume of a cylinderv = πr²hwhere
r = radius
h = height
The grain silo is in the form of a right cylinder. Therefore,
diameter = 14 ft
radius = 14 / 2 = 7 ft
height = 30 ft
The cubic ft of corn that will contain the silo is the volume. Therefore,
v = 3.14 × 7² × 30
v = 3.14 × 49 × 30
v = 4615.8
v = 4615.8 ft³
