what 18/25 as a percent and decimal
In order to write [tex]\frac{18}{25}[/tex] as a decimal, we need to find a fraction equivalent to[tex]\frac{18}{25}[/tex] with a 100 in the denominator. Notice that if we multiply the numerator and the denominator of [tex]\frac{18}{25}[/tex] by 4, we get the equivalent fraction [tex]\frac{72}{100}[/tex] which we can now write as a decimal. Remember that the hundredths place is 2 places to the right of the decimal point. Therefore, we can write [tex]\frac{72}{100}[/tex] as 0.72.
To write a fraction to a percent, first remember that a percent is a ratio of a number to 100 so to write [tex]\frac{18}{25}[/tex] as a percent, we need to find a fraction equivalent to [tex]\frac{18}{25}[/tex] that has a 100 in the denominator. We can . do this by setting up a proportion.
[tex]\frac{18}{25}[/tex] ≈ [tex]\frac{n}{100}[/tex]
Now, we can use cross products to find the missing value.
25n = 1800
÷ 25 ÷25
n = 72%
Therefore, [tex]\frac{18}{25}[/tex] is equal to 72%.

Eddie goes jogging every other day, lifts weights every third day, and swims every fourth day. If Eddie begins all three activities on Monday , how many days will it be before he does all three activities on the same day again?
(BTW YOU'RE SUPPOSED TO USE LCM)
By applying the concept of Least Common Multiple (LCM), which is 12 in this case, we realize that Eddie will perform all three activities on the same day again after 12 days and that the day will be a Friday.
Explanation:If Eddie goes jogging every other day (2 days), lifts weights every third day (3 days), and swims every fourth day (4 days), then we must find the LCM of 2, 3, and 4 to find out when will he do all three activities on the same day again.
The LCM of 2, 3, and 4 is 12. Therefore, Eddie will perform all three activities on the same day after 12 days. If he begins on Monday, he will surprisingly end up on a Friday, as the 12th day falls on a Friday. This is because, typically, 7 days from Monday is another Monday. Therefore, five additional days (to total 12) will fall on a Friday.

Find an equation of the tangent line to the curve
xey + yex = 5
The equation of the tangent line to the curve is derived by first finding the slope of the tangent line at a certain point using implicit differentiation. After finding the slope, we then use the point-slope form of a linear equation to get the equation of the tangent line.
Explanation:To find an equation of the tangent line to the curve given by the equation xey + yex = 5, it's necessary to find the derivative of the function, which gives us the slope of the tangent line at any point. Implicit differentiation is the key here, since y is not explicitly solved in terms of x.
Differentiating the given equation implicitly with respect to x, we get: exy + yex +ex + yex = 0. From this, we can express dy/dx (the derivative of y with respect to x, i.e., the slope of the tangent line) in terms of x and y.
Next, simply plug in the given coordinates of the point at which we are finding the tangent into this dy/dx equation. This gives the slope of the tangent line at the specific point.
To finally find the equation of the tangent line, use the point-slope form of a linear equation y - y1 = m(x - x1), where m is the slope we found, and (x1, y1) are the coordinates of the point. Substitute these values in, and that gives the equation of the tangent line to the curve at the point.

Which expression represents the composition g(f(x)) for the functions below?
f(x) = –3x2
g(x) = 3x
Answer:
[tex]g(f(x))=-9x^2[/tex]
Step-by-step explanation:
[tex]f(x) = -3x^2[/tex]
[tex]g(x) = 3x[/tex]
WE need to find composition of function g(f(x))
To find g(f(x)) we replace f(x) in g(x)
[tex]g(f(x))= g(-3x^2)[/tex]
Now we replace -3x^2 inside g(x)
[tex]g(-3x^2)=3(-3x^2)= -9x^2[/tex]
[tex]g(f(x))=-9x^2[/tex]
three kids named ricky, bobby, and terry have a total of 68 tech decks. Ricky has 8 more than bobby. terry has triple the number bobby has how many tech decks does each kid have?
Final answer:
Bobby has 12 tech decks, Ricky has 20 tech decks, and Terry has 36 tech decks.
Explanation:
Let's represent the number of tech decks each child has using variables.
Let's say Bobby has x tech decks. Since Ricky has 8 more tech decks than Bobby, Ricky has x + 8 tech decks. Terry has triple the number of tech decks that Bobby has, so Terry has 3x tech decks.
Now, we can set up an equation to represent the total number of tech decks:
x + x + 8 + 3x = 68
5x + 8 = 68
5x = 60
x = 12
So, Bobby has 12 tech decks, Ricky has 12 + 8 = 20 tech decks, and Terry has 3 * 12 = 36 tech decks.

I have 28 toys that are solar 2/7 of them are Disney characters how many solar toys are Disney characters
Final answer:
To find out how many solar toys are Disney characters, multiply the total number of toys by the fraction of toys that are Disney characters.
Explanation:
To find out how many solar toys are Disney characters, we need to multiply the total number of toys by the fraction of toys that are Disney characters. In this case, 2/7 of the toys are Disney characters. So, we can calculate:
Number of solar Disney toys = Total number of solar toys × Fraction of Disney toys
Number of solar Disney toys = 28 × 2/7 = 8
Therefore, there are 8 solar toys that are Disney characters.
In which figure is DE\\BC ? figure 1 figure 2 figure 3 figure 4
In Figure 4, in the triangle ΔABC, DE is parallel to BC, i.e., DE||BC.
A triangle is one of the most basic geometric figures, having 3 sides, 3 angles, and 3 vertices.
By the theorem of the triangle, if a line divides any two sides of a triangle in the same ratio, then the line is parallel to the third side. Let's check the theorem holds for which triangle in the given figures.
Figure 1:
[tex]\frac{AD}{BD} = \frac{6}{15} =\frac{2}{5}[/tex]
[tex]\frac{AE}{CE} = \frac{6.6}{17.5} =\frac{66}{175}[/tex]
Since, [tex]\frac{AD}{BD}\neq \frac{AE}{CE}[/tex],
Here, in triangle ABC, DE is not parallel to BC.
Figure 2:
[tex]\frac{AD}{BD} = \frac{5}{12}[/tex]
[tex]\frac{AE}{CE} = \frac{6}{15} =\frac{2}{5}[/tex]
Since, [tex]\frac{AD}{BD}\neq \frac{AE}{CE}[/tex],
Here, in triangle ABC, DE is not parallel to BC.
Figure 3:
[tex]\frac{AD}{BD} = \frac{4}{12} =\frac{1}{3}[/tex]
[tex]\frac{AE}{CE} = \frac{5}{16}[/tex]
Since, [tex]\frac{AD}{BD}\neq \frac{AE}{CE}[/tex],
Here, in triangle ABC, DE is not parallel to BC.
Figure 4 :
[tex]\frac{AD}{BD} = \frac{5.5}{15}[/tex]
[tex]= \frac{55}{150}\\ = \frac{11}{30}[/tex]
[tex]\frac{AE}{CE} = \frac{6.6}{18}[/tex]
[tex]=\frac{66}{180}\\ =\frac{11}{30}[/tex]
Since, [tex]\frac{AD}{BD} = \frac{AE}{CE}[/tex],
