Answer:
Move the decimal point two places to the left
Step-by-step explanation:
Answer:
To change a percent to a decimal we divide by 100. This is the same as moving the decimal point two places to the left. For example, 15% is equivalent to the decimal 0.15.

rationalize the denominator of 1/√3
Answer:
√3/3
Step-by-step explanation:
Multiply the numerator and denominator by the conjugate.
Hope this helps!! Please consider marking brainliest! Have a good one!!
Step 1: Multiply numerator and denominator by a radical that will get rid of the radical in the denominator.
If the radical in the denominator is a square root, then you multiply by a square root that will give you a perfect square under the radical when multiplied by the denominator. If the radical in the denominator is a cube root, then you multiply by a cube root that will give you a perfect cube under the radical when multiplied by the denominator and so forth...
Note that the phrase "perfect square" means that you can take the square root of it. Just as "perfect cube" means we can take the cube root of the number, and so forth.
Keep in mind that as long as you multiply the numerator and denominator by the exact same thing, the fractions will be equivalent.
Step 2: Make sure all radicals are simplified.
Some radicals will already be in a simplified form, but make sure you simplify the ones that are not. If you need a review on this, go to Tutorial 39: Simplifying Radical Expressions.
Step 3: Simplify the fraction if needed.
Be careful. You cannot cancel out a factor that is on the outside of a radical with one that is on the inside of the radical. In order to cancel out common factors, they have to be both inside the same radical or be both outside the radical.

Describe a pattern in each sequence. Then find the next two terms of the difference.
1, 5, 25, 125, …
1, 5, 25, 125
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by
5 gives the next term. In other words, an=a1⋅rn−1. Geometric Sequence: r=5
This is the form of a geometric sequence.an=a1rn−1 Substitute in the values of a1=1 and r=5.an=(1)⋅(5)n−1 Multiply (5)n−1 by 1. an=5n−1

Devin is buying 2 concert tickets. The concert tickets have a regular price of $40 each. Devin has a coupon that gives a 5% discount off of the regular price of the tickets. He will then pay a 10% purchasing fee on the discounted price of the tickets. What is Devin's total cost of the two tickets after the discount and the fee?
Given :
Devin is buying 2 concert tickets. The concert tickets have a regular price of $40 each.
Devin has a coupon that gives a 5% discount off of the regular price of the tickets. He will then pay a 10% purchasing fee on the discounted price of the tickets.
To Find :
Devin's total cost of the two tickets after the discount and the fee.
Solution :
Discount on price, D = 40×0.05 = $2 .
Price of product after discount, P = $( 40 - 2 ) = $38 .
Now, total price after adding purchasing fee is :
T = P + (P×0.10)
T = 38 + (38×0.10)
T = 38 + 3.8
T = $41.8
Therefore, Devin's total cost of the two tickets after the discount and the fee is $41.8 .
Hence, this is the required solution.
Mrs. Mireles needs to hire landscapers to maintain her yard. Company L charges $250 per month plus $30 per hour. Company S charges $200 per month plus $35 per hour. Which inequality can be used to find x, the minimum number of hours each company would have to work so that the total charges from Company L is less than the total charges from Company S?
Answer:
10 hoursStep-by-step explanation:
Step one:
given information
Company L charges
monthly charge= $250
hourly charge= $30
let the total charge be y
and the number of hours be x
y=30x+250----------1
Company S charges
monthly charge= $200
hourly charge= $35
let the total charge be y
and the number of hours be x
y=35x+200------------2
Step two:
equating 1 and 2
30x+250=35x+200
collect like terms
30x-35x=200-250
-5x=-50
x=50/5
x=10
10 hours

10,24,26 determine whether the triangle is obtuse, right, acute, or not a triangle
Answer:
right triangle
Step-by-step explanation:
10 + 24 = 34
34 > 26
Therefore, there is a triangle.
Now we use the Pythagorean theorem.
10^2 + 24^2 = 100 + 576 = 676
26^2 = 676
Since 10^2 + 24^2 = 26^2, the triangle is a right triangle.

Question
Enter an equation in point-slope form for the line.
(2, 4) and (3, 3) are on the line.
An equation of the line in point slope form is:
Given:
(2, 4) and (3, 3) are on the line.
To find:
The equation of line in point slope form.
Solution:
If a line passes through a point [tex](x_1,y_1)[/tex] with slope m, then the point slope form of the line is
[tex]y-y_1=m(x-x_1)[/tex]
(2, 4) and (3, 3) are on the line. So, slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{3-4}{3-2}[/tex]
[tex]m=\dfrac{-1}{1}[/tex]
[tex]m=-1[/tex]
The slope of a line is -1 and it passes through (2,4). So, an equation in point slope form is
[tex]y-4=-1(x-2)[/tex]
Therefore, an equation of the line in point slope form is [tex]y-4=-1(x-2)[/tex].

Step-by-step explanation:
Manuel y Carlos encuentran un libro de matemática usado y en una de las hojas se observa la figura de un poliedro demasiado borrosa, pero se ven algunos datos sobre él que dicen: El poliedro tiene 12 aristas y la suma de su número de caras con su número de vértices es 14. Manuel afirma que se trata de un dodecaedro y Carlos dice que es un cubo. ¿Quién de ellos tiene la razón?
Answer:
Carlos tiene razón. El poliedro es un cubo.
Step-by-step explanation:
Comencemos analizando el número de caras del dodecaedro y del cubo.
El dodecaedro está conformado por 12 caras.
El cubo en cambio, está conformado por 6 caras.
En cuanto a aristas el dodecaedro tiene 30 aristas y en cambio el cubo tiene 12. Por ende, descartamos la idea de que el poliedro sea un dodecaedro.
Finalmente en cuanto a vértices, el dodecaedro tiene 20 vértices y el cubo tiene 8 vértices.
Si sumamos el número de caras y el número de vértices en el cubo obtenemos :
6 + 8 = 14
Con esto, verificamos que la figura borrosa es de un cubo y que Carlos tiene razón.

Write the equation of the line that passes through the points (-2,0) and (1,2).
Answer:
y = 2/3x + 1 1/3
Step-by-step explanation:
Find the slope using rise over run, (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(2 - 0) / (1 + 2)
2 / 3
= 2/3
Then, plug in the slope and a point into y = mx + b to solve for b:
y = mx + b
2 = 2/3(1) + b
2 = 2/3 + b
1 1/3 = b
Plug in the slope and y intercept into y = mx + b
y = 2/3x + 1 1/3 is the equation of the line

i just used the pythagorean theorem, you can copy my work.
can someone help me out? i’m not sure what the answers would be for these 5, thanks.
Answer:
<6 and 4 are supplementary angles. Supplementary angles add up to 180. therefore <6 and <4=180--->m<6=65---->180-65=115---> m<4-115
2. 115°
By using vertical angles theorem we see that angles opposite to each other like 5 and 8 are congruent.
Therefore m<8 = m<5
3. 122
<3 and <6 are congruent by the alternate interior angles theorem which states that interior angles that are opposite one another such as 6 and 3 are congruent.
4. 73°
<4 and <7 are supplementary since the <4 is equal to the <8 and the <8 is supplementary to 7.
180-107=73
5. 73°

what value of P makes the equation true
-3p+1/8= -1/4
Step-by-step explanation:
Hey there!
Given;
-3p + 1/8 = -1/4
Simplify it to get the value of"p".
[tex] - 3p + \frac{1}{8} = - \frac{1}{4} [/tex]
[tex] \frac{ - 24p + 1}{8} = \frac{ - 1}{4} [/tex]
[tex] 4(- 24p + 1) = - 1 \times 8[/tex]
[tex] - 96p + 4 = - 8[/tex]
[tex] - 96p = - 8 - 4[/tex]
[tex]p = \frac{ - 12}{ - 96} [/tex]
[tex]p = \frac{ 1}{8} [/tex]
Therefore, p = 1/8.
Check:
-3*1/8 +1/8 = -1/4
-3/8+1/8= -1/4
-1/4 = -1/4
Therefore, the value of "p" must be (1/8) to satisfy the equation.

A coordinate map of the local grocery store is shown below. Ice cream is located at the point (-8,0)(−8,0)left parenthesis, minus, 8, comma, 0, right parenthesis. Sprinkles are located at the point (-8,6)(−8,6)left parenthesis, minus, 8, comma, 6, right parenthesis. PLEASE HELP ME!!
Answer:
Step-by-step explanation:
If on the coordinate map, ice cream is located at the point (-8,0) and sprinkles are located at the point (-8,6), we can find the distance between the coordinate points using the formula;
D = √(x2-x1)²+(y2-y1)²
Given
x1 = -8, y1 = 0, x2 = -8 and y2 = 6
Substitute
D = √(x2-x1)²+(y2-y1)²
D = √(-8-(-8))²+(6-0)²
D = √0²+6²
D = √36
D = 6units
Hence the distance between the coordinate points is 6units
