What is the solution set of 6x2-24 = 0?
(-2.2
Answer:
x = { - 2, 2 }
Step-by-step explanation:
Given
6x² - 24 = 0 ( add 24 to both sides )
6x² = 24 ( divide both sides by 6 )
x² = 4 ( take the square root of both sides )
x = ± [tex]\sqrt{4}[/tex] = ± 2
solution set is { - 2, 2 }

The price of a pair of shoes increases from $65 to $81. What is the percent increase to the
nearest percent?
Answer:
Percent increase = 25%
Step-by-step explanation:
Given that:
Old price of shoes = $65
New price of shoes = $81
Difference = 81 - 65
Difference = 16
Percent increase = [tex]\frac{Difference}{Old\ price}*100[/tex]
Percent increase = [tex]\frac{16}{65}*100[/tex]
Percent increase = 0.246 * 100
Percent increase = 24.6%
Rounding off to nearest whole number
Increase = 25%
Hence,
Percent increase = 25%

two angles of an isosceles triangle are x and x+10.find two possible value of x
Recall two important facts:
- An isosceles triangle always has two identical angles
- The interior angles always add up to 180 degrees
Armed with this info, we can set up two different equations to solve for x, depending on which angle we treat as being one of the pair of identical angles.
If we assume that the identical angles are x, then:
180 = 2x + x + 10
170 = 3x
56[tex]\frac{2}{3}[/tex] = x
Alternately, we can assume that the identical angles are x+10. In this case:
180 = 2(x + 10) + x
180 = 2x + 20 + x
160 = 3x
53[tex]\frac{1}{3}[/tex] = x
An arc subtends an angle of 72 degree at the circumference of a circle of radius 5 cm. calculate the length of the arc in terms of pie

Find the percent change if the original is $300 and the new cost is $1,100?
The percentage change from $300 to $1,100 is 266.67% increase
How?
1,100 - 300 ÷ 300 = 2.6667
2.6667 x 100 = 266.67%
^this is how you find the percent in change
(You could have just asked me to show my work instead of reporting me- that was a bit uncalled for)
Answer: $266.667% change
Step-by-step explanation:
(V2 - V3) (1100 - 300) 800
_______ x100 = ________ x 100 = ____ x 100= $2.66667% = $266.667%
V1 300 300 x 100 increase or change

An estimate of the height, H metres, of a tall building can be found
using the formula
H = 3f + 15
where the building is f floors high.
A building is 85 floors high.
The real height of the building is 260m.
Work out the percentage error when estimating the height of this building using
the formula given.
Given that,
An estimate of the height, H metres, of a tall building can be found using the formula :
H = 3f + 15
where the building is f floors high.
f = 85
The real height of the building is 260 m.
To find,
The percentage error.
Solution,
We have,
H = 3f + 15
Put f = 85 in the above formula
H = 3(85) + 15
H = 270 m
Error,
[tex]E=\dfrac{270-260}{260}\times 100\\\\=3.84\%[/tex]
So, the required error is 3.84%.

An item is regularly priced at $65. Abdul bought it at a discount of 95% off the regular price. Use the ALEKS calculator to find how much Abdul paid.
Answer:
$3.25
Step-by-step explanation:
An item is regularly priced at $65. Abdul bought it at a discount of 95% off the regular price. Use the ALEKS calculator to find how much Abdul paid.
Original price of item = $65
percent discount = 95%
discount price = 95% * 65
discount price = 0.95 * 65
discount price= $61.75
Amount abdul paid = Original price - discounted price
Amount abdul paid = $65 - $61.75
Amount abdul paid = $3.25
Hence abdul paid $3.25
A bouquet of flowers contains a total of 24 red and white roses. The number of red roses is 4 less than three times the number of white roses.
How many of each color rose are in the bouquet?
(with preferred work)
Answer:
White roses - 7
Red roses - 17
Step-by-step explanation:
Set up proportional equations
White roses = x
Red roses = 3x - 4
Set equal to 24
x + 3x - 4 = 24
4x - 4 = 24
4x = 28
x = 7
x is white roses, so there are 7
Plug x value into red rose equation
3(7)-4
21-4 = 17 red roses
Check
17+7 = 24
