Sophie can type 128 words in three minutes how many minutes will it take her to type 576 words?
Answer:
13 minutes and 30 seconds
Step-by-step explanation:
Okay so first you would divide 128 by 576. But since it takes her 3 minutes just to type 128 words you have to multiply 4.5 times 3. It will take her 13.5 minutes to type 576 words or 13 minutes and 30 seconds.

What is an equation of the line that passes through the points (-4, 8) and
(2, -1)?
Answer:
Kayla, learn this, :D more math is based on it. Just learn it, just memorize the following
Step-by-step explanation:
m = slope
m = rise / run
m = y2 - y1 / x2 - x1 ( this is still rise over run but in point form )
they give us two points to plug into the above formula
P1 = (-4, 8 ) in the form of ( x1, y 1 )
P2 = (2, -1) in the form of (x2, y2 )
now plug those into the above formula
m = ( -1 - 8 ) / ( 2-(-4) )
m = -9 / ( 2 + 4 )
m = -9 / 6
m = - 3/2
since we know the slope now , we can use the point slope equation of
y - y1 = m ( x - x1)
use the m we found and either point , P1 or P2
y - 8 = -3/2(x -(-4) )
y-8 = -3/2(x + 4)
y-8 = -3/2x - 6
y = -3/2x -6 + 8
y = -3/2x + 2
there you go :)
What is the surface area of this triangular pyramid?
___square inches
Answer:
Surface area = 10.7 in.²
Step-by-step explanation:
Surface Area of triangular pyramid = BA + P*L
Base Area (BA) = ½*nh
b = 2 in.
h = 1.7 in.
BA = ½*2*1.7 = 1.7 in.²
Perimeter (P) = 2 + 2 + 2 = 6 in.
Slant height (L) = 3 in.
Plug in the values
Surface Area = 1.7 + ½*6*3
Surface area = 10.7 in.²

help please ? I don’t understand I’m in 6th grade
Answer:
22/7 - irrational number
1.141141114 - irrational number
17/4 - rational number
-6 - integer
[tex]\frac{\pi }{2}[/tex] - irrational number
0 - whole number
9 - natural number and whole number
21/3 - natural number and whole number
Step-by-step explanation:
natural numbers would be numbers 1,2,3,4,5,6,7...
whole numbers would be numbers 0,1,2,3,4,5,6...
integers are negative whole numbers
rational numbers are fractions and numbers that have decimal points
irrational numbers are number such as [tex]\pi[/tex] or [tex]\sqrt{5}[/tex]
X1 + X2 =-8
3X1 +2X2 = 18
Answer:
X1 = 34
X2 = -42
Step-by-step explanation:
Given the simultaneous equations
X1 + X2 =-8 .... 1 * 3
3X1 +2X2 = 18 .... 2 * 1
______________________
3X1 + 3X2 = -24
3X1 +2X2 = 18
Subtract
3X2 - 2X2 =-24 - 18
X2 = -42
Substitute X2 = -42 into 1
X1 + X2 = -8
X1 - 42 = -8
X1 = -8+42
X1 = 34
Hence the solution to the system of equation is (34, -42)

the sum of 2 fractions 8/9. the difference 2/9. what are the 2 fractions?
Answer:
5/9 and 3/9
Step-by-step explanation:
run through the different possibilities and see what has a difference of 2/9th. Here is the way I ran through it
1/9 + 8/9 Difference is not 2/9th
2/9 + 6/9 Difference is not 2/9th
3/9 + 5/9 Difference is 2/9th. This is our answer
Step-by-step explanation:
5/9 and 3/9.....add 5/9 and 3/9 and you will get 8/9....if you subtract 5 and 3 it will give you 2....5/9-3/9=2/9
What is the common difference between successive terms in the sequence?
2, 8, 14, 20, 26, ...
-6
-4
ООО

о в
Let be a1 = 8 and a2 = 8 [ From question ]
We have to find out common differences which denoted by letter d .
d = a2 - a1 [ Formula ]
= 8 - 2
= 6
Thus,the common difference between successive terms in the sequence is 6 .
Answer:
6.
Step-by-step explanation:
We have to find out common differences which denoted by letter d .
d = a2 - a1 [ Formula ]
= 8 - 2
= 6
Also,
2+6=8 +6=14 +6=20 +6=26
So, It's Added Up By 6.
Give triangle ABC with coordinates A(3, 8), B(9,0) and C(5,2). How can you prove that triangle ABC is isosceles? Show your work.
Answer:
The distances AB and BC are
√
52
and therefore isosceles.
Explanation:
If we label them A(13,-2) B(9-8) and C(5-2)
The distance between A and B:13⇒9=4−2⇒−8=42+62=52 so the distance is √52
The distance between B and c:9⇒5=4−8⇒−2=642+62=52
the distance is
√
52
The distance between A and C is 8 as they are both on -2 for
y
The distances AB and BC are
√
52
and therefore isosceles.Step-by-step explanation:
Two sides of a right triangle are 8 and 12. Find the missing side of 8 and 12 are a leg and a hypotenuse.
Answer:
8.94 if no rounding is necessary.
Step-by-step explanation:
Pythagorean Theorem. What we know is only one leg and the hypotenuse, sooo...
8² + b² = 12²
64 + b² = 144
Subtract 64 from both sides...
64 - 64 + b² = 144 - 64
b² = 80
[tex]\sqrt{80}[/tex] = 8.94 if you're not rounding.
Data from a representative sample were used to estimate that 31% of all computer users in a recent year had tried to get on a Wi-Fi network that was not their own in order to save money. You decide to conduct a survey to estimate this proportion for the current year. What is the required sample size if you want to estimate this proportion with a margin of error of 0.05
Answer:
The required sample size is 329.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
31% of all computer users in a recent year had tried to get on a Wi-Fi network that was not their own in order to save money.
This means that [tex]\pi = 0.31[/tex]
Confidence level is not given, so we assume 95%.
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
What is the required sample size if you want to estimate this proportion with a margin of error of 0.05?
We need a sample size of n. n is found when M = 0.05. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.05 = 1.96\sqrt{\frac{0.31*0.69}{n}}[/tex]
[tex]0.05\sqrt{n} = 1.96\sqrt{0.31*0.69}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.31*0.69}}{0.05}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.31*0.69}}{0.05})^2[/tex]
[tex]n = 328.6[/tex]
Rounding up
The required sample size is 329.
Romell receives five points for each correct answer on a
test and loses two point for each incorrect
answer.
a. Write an equation showing that Reggie received 30 points.
6x = 30
b. Write an equation showing that Reggie answered all 35 questions on the
test.
Answer:
5x - 2y = 30
x + y = 35
Step-by-step explanation:
Number of correct answers = x
Number of incorrect answers = y
Points won per correct answer = 5
Points lost per incorrect answer = 2
If Reggie received 30 points :
Required equation :
(points won per correct answer * number of correct answers) + (points lost per incorrect answer * number of incorrect answers)
5x + (-2y) = 30
5x - 2y = 30
Equation showing that Reggie answer all 35 questions :
Number of correct answers + number of incorrect answers = 35
x + y = 35
What is the population in 2020 of a place that has a population of 4 million people in 2011 and is growing at a rate of 1.3%?
Answer:
370 million
Step-by-step explanation:
In the 10 years from 2000 to 2010, the population was multiplied by the factor ...
100% + 9.6% = 109.6% = 1.096
In the next 20 years from 2010 to 2030, the population will be multiplied by that factor twice, if it grows at the same rate:
2030 population = (308 million)·(1.096²) ≈ 370 million
