Step-by-step explanation:
Step 1: Write down the percent divied by 100 like this: percent/100
Step 2: If the percent is not a whole number, then multiple both top and bottom by 10 for every number after the decimal point. (for example, if there is on number after the decimal, then use 10, if there are two then use 100, ect.)
Step 3: simplify.(or reduce) the fraction
The price of a calculator is increased by 99 % and now is $ 883.56 . Find the original price.
Answer:
$444
Step-by-step explanation:
1.99 * x = 883.56 [The price has increased by 99%, so you multiply it by 1 + 0.99]
x = 444
Answer:
The original price of the calculator was $444
Step-by-step explanation:
So follow this equation
1.99x=883.56
1.99 becuase 99 percent is the .99 and since the original price with no change of all is worth 100 percent With no sales or increases, we add the 99 percent this time becuase it increased by 99%.
X is for the original price of the calculator
If you still don’t undertsand it works like this.
100% is basically 1.00 becuase you move the decimal place 2 times to the left for percentages. And if you multiply the original price by 100 percent, its basically 1x which will end up with x. Same thing. But when you increase a price, you add to the 1.00 like in this case 99% increase which is adding .99 to 1.00. If it decreases same thing except you subtract from that 1.00 But the percent. this saves a whole nother step Which makes percentage questions liek these much quicker and easier.
Alright so the eqaution is 1.99x=883.56
Solve by isolating x by dividing 1.99 on both sides
You’d get 444=x
$444 is the original price

Answer:
x = 6
Step-by-step explanation:
Tip: You want to isolate the x-variable on one side of the equation to find its value.
1) First, get rid of the radical signs on both sides of the equation by squaring both sides. This should leave you with 5x-7 = 3x+5.
2) Get the x-variables on one side by subtracting 3x from both sides, so the equation should be 2x-7=5.
3) Solve for x by adding 7 to both sides, so that your equation looks like this: 2x = 12.
4) Divide both sides by 2 and you will get x = 6. You can verify 6 as the x-value by plugging 6 back into the original equation.
I hope that helps! :)

Step-by-step explanation:
Pythagorean theorem
[tex]a^{2} + b^{2} =c^{2}[/tex]
a = perpendicular
b = base
c = hypotenuse
we have to find the hypotenuse
so,
[tex]13^{2} + 29.25^{2} = c^{2} \\169 + 855.6 = c^{2}\\1024.6 = c^{2}\\\sqrt{1024.6} = \sqrt{c^{2}} \\c = 32[/tex]

Answer:
B 4
Step-by-step explanation:
Can A is 8 x 8π, or 64π, where the radius 4 was multiplied by 2 to get diameter and then by π to get length of can.
Can B is 4 x 4π, or 16π, where the radius of 2 is multiplied by 2 to get diameter and then by π to get length of can.
Can B can be painted 4 times over to paint same amount as Can A.

Given:
The value is [tex]\dfrac{\sqrt{2}}{2}[/tex].
To find:
The values from the given options which are equal to the given value.
Solution:
We have,
[tex]\dfrac{\sqrt{2}}{2}[/tex]
It can be written as:
[tex]\dfrac{\sqrt{2}}{2}=\dfrac{1}{\sqrt{2}}[/tex]
From the standard trigonometric table, we get
[tex]\sin 30^\circ=\dfrac{1}{2}[/tex]
[tex]\sin 45^\circ=\dfrac{1}{\sqrt{2}}[/tex]
[tex]\cos 45^\circ=\dfrac{1}{\sqrt{2}}[/tex]
[tex]\cos 60^\circ=\dfrac{1}{2}[/tex]
[tex]\tan 30^\circ=\dfrac{1}{\sqrt{3}}[/tex]
[tex]\tan 45^\circ=1[/tex]
From the above values it is clear that the value of [tex]\sin 45^\circ [/tex] and [tex]\cos 45^\circ [/tex] are equal to [tex]\dfrac{1}{\sqrt{2}}[/tex].
Therefore, [tex]\sin 45^\circ [/tex] and [tex]\cos 45^\circ [/tex] and equal to [tex]\dfrac{\sqrt{2}}{2}[/tex]. So, options B and C are correct.
A scoop used to measure
powdered drink mix is in
the shape of a cone with a
radius of 5 cm
What is the height of the scoop if its volume is 75pi cm cube
Answer:
9
Step-by-step explanation:
V=pi (r squared) (h/3)
75pi = 25pi (h/3)
Divide both sides by 25 pi
3= h/3
Multiply both sides by 3
h=9

Ms. Johnson buys a family-size bag of chips. She gives 20% to Jackie. Another 20% to Ronald. Ms. Johnson gives 1/4 to Mark and Susan takes 1/2 of what's left. What percent does Ms. Johnson has left to eat?
Answer: 17.5%
Step-by-step explanation:
Percentage of chips given to Jackie = 20%
Percentage of chips given to Ronald = 20%
Percentage of chips given to Mark = 1/4 × 100 = 25%
From the above calculation, we can see that Ms Johnson has given out ((20% + 20% + 25%) = 65% worth of chips out. The percentage she'll have left will be:
= 100 - 65
= 35%
Since Susan takes half of what's left, the percent that Ms. Johnson has left to eat will be:
= 1/2 × 35%
= 17.5%
She has 17.5% left to eat.

Answer:
Vertical angles: <3 and <8, <2 and <5, <1 and <6, <4 and <7 (choose one pair, these are all right)
Linear: <1 and <5, <2 and <6, <3 and <7, <4 and <8, there are more (choose one pair, all these are right)
Congruent: Choose one of the vertical angle pairs I listed above
Step-by-step explanation:
Vertical angles are diagonally across for each other and equal the same angle. You would get a better explanation if you looked up pictures.
Linear angles are two angles on a straight line that are divided by another line. Again, you would get a better explanation by looking at a visual
Congruent angles are equal to each other, and because there are no angle measures here, you would go with a vertical angle pair.
Answer:
Step-by-step explanation:
Vertical angles: <3 and <8, <2 and <5, <1 and <6, <4 and <7 (choose one pair, these are all right)
Linear: <1 and <5, <2 and <6, <3 and <7, <4 and <8, there are more (choose one pair, all these are right)
Congruent: Choose one of the vertical angle pairs I listed above
