Answer:
27 mg
Step-by-step explanation:
divide 180 by 20 to get 9
then multiply 9 by 3
you should get 27mg
Describe two different ways that you could find the product 3x990
990 = 1000 - 10
so 3 x 990 = 3 x (1000 - 10) = 3 x 1000 + 3 x (-10) = 3000 - 30 = 2970
and
990 = 900 + 90
so 3 x 990 = 3 x (900 + 90) = 3 x 900 + 3 x 90 = 2700 + 270 = 2970

What is the slope and y-intercept of this line?
y=−12x+7
Answer:
-12
Step-by-step explanation:
y = mx + b
the one being multiplied to x is the slope
Answer:
slope: -12
y-intercept: 7
Step-by-step explanation:
The slope-intercept form of the equation of a line is
y = mx + b
where m = slope, and b = y-intercept.
Your equation is
y = -12x + 7
Your equation is already in the slope-intercept form.
m = -12
b = 7
slope: -12
y-intercept: 7

Damita says the equations 0.8x - 0.8 = 1.6 and 4/5 ( x - 1 ) = 1 (3/5) are the same. How can she show this without solving the equations?
To show that the equations are the same, we need to rewrite one of the equations as an equivalent equation of the second
Damita's claim is true
How to show the equations are the sameThe equations are given as:
0.8x - 0.8 = 1.6
4/5 ( x - 1 ) = 1 (3/5)
We need to rewrite one of the equations, as follows:
4/5 ( x - 1 ) = 1 (3/5)
Express as decimal
0.8 ( x - 1 ) = 1 + 0.6
Open the brackets
0.8x - 0.8 = 1.6
Now we have:
0.8x - 0.8 = 1.6 (the first equation) and 0.8x - 0.8 = 1.6 (the equivalent of the second equation)
The above shows that both equations are the same

You and your friends order a meal for $116.29. How much tip should you leave if you want to leave a 12% tip?
Answer:
$13.95
Step-by-step explanation:
$166.29 ×12/100
=$13.95 will be the tip.
Answer:
$13.95
Step-by-step explanation:
Convert the 12% to an actual number that can be used in a calculator. For percents, this is done by dividing the percent (in this case 12%) by 100%.So, the conversational term "12%" becomes 12% / 100% = 0.12 in terms of a real mathematical number. Then you need to find out what 12% of your $116.29 meal cost is.This is always done by multiplying 0.12 by $116.29, or 0.12 x $116.29=$13.95.

Find the value of x.

Answer:
x° = 80°Step-by-step explanation:
[tex] {x}^{o} + {115}^{o} + {95}^{o} + {70}^{o} = {360}^{o} \\ [/tex]
(The measure of the interior angle of a square is 90°)
[tex]{x}^{o} + {115}^{o} + {95}^{o} + {70}^{o} = {360}^{o} \\ {x}^{o} + {280}^{o} = {360}^{o} \\ {x}^{o} = {360}^{o} - {280}^{o} \\ {x}^{o} = {80}^{o} \\ [/tex]
The sum of all the terms in an infinite geometric sequence is 81 and the sum
of all terms starting from the third is 9. What is the second term in the sequence?
Step (1)
We know that the sum of all the terms in an infinite geometric sequence finding from following equation whenever |q| < 1 .
q = magnitude
[tex]s( \infty ) = \frac{t(1)}{1 - q} \\ [/tex]
So :
[tex]s( \infty ) = \frac{t(1)}{1 - q} \\ [/tex]
[tex]81 = \frac{t(1)}{1 - q} \\ [/tex]
[tex]81(1 - q) = t(1)[/tex]
Remember it I'll use it again.
_________________________________
Step (2)
We know that the sum of the n first terms of a geometric sequence finding from following equation.
[tex]s(n) = \frac{t(1) \times (1 - {q})^{n} }{1 - q} \\ [/tex]
_________________________________
Sum of all terms starting from the third is 9.
So :
[tex]s(2) + s(3 - \infty ) = 81[/tex]
[tex]s(2) + 9 = 81[/tex]
Sides minus 9
[tex]s(2) = 81 - 9[/tex]
[tex]s(2) = 72[/tex]
So :
[tex]t(1) + t(2) = 72[/tex]
[tex]t(1) + t(1) \times q = 72[/tex]
Factoring t(1)
[tex]t(1) \times (1 + q) = 72[/tex]
We have found t(1) = 81 ( 1 - q ) in step (1).
So :
[tex]81(1 - q)(1 + q) = 72[/tex]
Divided sides by 81
[tex](1 - q)(1 + q) = \frac{72}{81} \\ [/tex]
[tex](1 - q)( 1 + q) = \frac{8}{9} \\ [/tex]
[tex]1 - {q}^{2} = \frac{8}{9} \\ [/tex]
Subtract sides minus -1
[tex] - {q}^{2} = \frac{8}{9} - 1 \\ [/tex]
[tex] - {q}^{2} = \frac{8}{9} - \frac{9}{9} \\ [/tex]
[tex] - {q}^{2} = - \frac{1}{9} \\ [/tex]
Negatives simplifies
[tex] {q}^{2} = \frac{1}{9} \\ [/tex]
Radical sides
[tex]q = + \frac{1}{3} \\ q = - \frac{1}{3} [/tex]
_________________________________
Step (4)
If q = 1/3 :
[tex]81(1 - q) = t(1)[/tex]
[tex]81(1 - \frac{1}{3}) = t(1) \\ [/tex]
[tex]81( \frac{2}{3}) = t(1) \\ [/tex]
[tex]t(1) = 27 \times 2[/tex]
[tex]t(1) = 54[/tex]
So :
[tex]t(2) = t(1) \times q[/tex]
[tex]t(2) = 54 \times \frac{1}{3} \\ [/tex]
[tex]t(2) = 18[/tex]
°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°
If q = - 1/3 :
[tex]81(1 - q) = t(1)[/tex]
[tex]81(1 - ( - \frac{1}{3})) = t(1) \\ [/tex]
[tex]81(1 + \frac{1}{3}) = t(1) \\ [/tex]
[tex]81( \frac{4}{3}) = t(1) \\ [/tex]
[tex]t(1) = 27 \times 4[/tex]
[tex]t(1) = 108[/tex]
So :
[tex]t(2) = t(1) \times q[/tex]
[tex]t(2) = 108 \times - \frac{1}{3} \\ [/tex]
[tex]t(2) = - 36[/tex]

Question 8! Need help please
An analyst wants to determine if there is any difference in the amount of time teenagers play video games between two years. To do this, he takes a random sample of teenagers and gathers the average time they spent playing video games the previous year and compares it to the average time they spent playing video games this year. Suppose that data were collected for a random sample of 15 teenagers, where each difference is calculated by subtracting the time spent playing video games this year from the time spent playing video games last year. Assume that the times are normally distributed. What is/are the critical value(s) of the t-test statistic for this hypothesis test, where α=0.10? Use a comma and a space to separate answers as needed.
Answer:
The critical value is [tex]t_{\frac{0.10}{2} , 14 } =[ - 1.761,1.761][/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 15
The level of significance is [tex]\alpha = 0.10[/tex]
The null hypothesis is [tex]H_o : \mu _1 = \mu_2[/tex]
The alternative hypothesis is [tex]H_a : \mu_1 \ne \mu_2[/tex]
Here [tex]\mu_1[/tex] is average time for previous year
[tex]\mu_2[/tex] is the average time for current year
Generally the degree of freedom is mathematically represented as
[tex]df = n -1[/tex]
=> [tex]df = 15 - 1[/tex]
=> [tex]df = 14[/tex]
Generally from the student t distribution table the critical value for [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of [tex]df = 14[/tex] for a two tailed test is
[tex]t_{\frac{0.10}{2} , 14 } =[ - 1.761,1.761][/tex]

A recipe calls for 112 teaspoons of cinnamon to make 2 dozen oatmeal cookies.
How many teaspoons of cinnamon are needed to make 60 oatmeal cookies?
Answer:
280
Step-by-step explanation:
112 ÷ 24 =4.66
4.66 x 60 =280
What are the x- and y-intercepts of the line?
2x – 3y = –12
x-intercept 6, y-intercept –4
x-intercept –4, y-intercept 6
x-intercept –6, y-intercept 4
x-intercept 4, y-intercept –6
Answer:
3rd option
Step-by-step explanation:
to find the x- intercept let y = 0 in the equation and solve for x
2x - 3(0) = - 12
2x - 0 = - 12
2x = - 12 ( divide both sides by 2 )
x = - 6 ← x- intercept
To find the y- intercept let x = 0 in the equation and solve for y
2(0) - 3y = - 12
0 - 3y = - 12
- 3y = - 12 ( divide both sides by - 3 )
y = 4 ← y- intercept
1) Find the general solution to the following differential equation x^3•y’- y = 0
Answer:
y(x) = c_1 e^(-1/(2 x^2))
Step-by-step explanation:
Solve the separable equation x^3 (dy(x))/(dx) - y(x) = 0:
Solve for (dy(x))/(dx):
(dy(x))/(dx) = y(x)/x^3
Divide both sides by y(x):
((dy(x))/(dx))/y(x) = 1/x^3
Integrate both sides with respect to x:
integral((dy(x))/(dx))/y(x) dx = integral1/x^3 dx
Evaluate the integrals:
log(y(x)) = -1/(2 x^2) + c_1, where c_1 is an arbitrary constant.
Solve for y(x):
y(x) = e^(-1/(2 x^2) + c_1)
Simplify the arbitrary constants:
Answer: y(x) = c_1 e^(-1/(2 x^2))
