Answer: 36 inches
Step-by-step explanation:
height of the building = 9inches.
scale factor of the building = 6:24.
solution
since a scale of 6:24, was used to scale down the original model, the initial or actual height of the statue would be.
[tex]= 9 * \frac{24}{6} \\\\= 9 * 4\\\\= 36 inches[/tex]
express the first quantity as a percentage of the second
a. 80cents of $9.60
Answer this question. please. I really need help
Answer:
8.33%
Step-by-step explanation:
We are told to:
Express the first quantity as a percentage of the second
a. 80cents of $9.60
The first quantity is 80 cents, the second quantity is $9.60
Step 1
We convert 80 cents to a dollar
100 cents = $1
80 cents = $x
$x = 80/100 = $0.8
Step 2
We express $0.8 as a percentage of $9.60
Hence, we have:
$0.8/$9.60 × 100
= 8.33%

Let x denote the average number of hours per week that a student at Happy High School spends doing homework. Suppose the frequency distribution of x is normal (i.E., symmetrical and bell-shaped) with a mean of 3.4 hrs. And a standard deviation of 2.6 hrs. What percentage of the students at Happy High spend an average of less than 6 hours per week doing homework?
Answer:
0.84134
Step-by-step explanation:
Given that:
Mean = 3.4 hours
Standard deviation (s) = 2.6 hours
Percentage of students that spend less than 6 hours doing homework
P(x < 6)
Using the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (6 - 3.4) / 2.6
Z = 2.6 / 2.6
Z = 1
p(Z < 1) = 0.84134 ( Z probability calculator)
The percentage of the students at Happy High spends an average of less than 6 hours per week doing homework is 0.84134
What is the equation of the line in point-slope form containing the points (4, -1) and (10, 0)?
Answer:
The equation of the line in point-slope will be:
[tex]y\:=\:\frac{1}{6}x-\frac{5}{3}[/tex]
Step-by-step explanation:
Given the points
(4, -1)(10, 0)Finding the slope between (4, -1) and (10, 0)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(4,\:-1\right),\:\left(x_2,\:y_2\right)=\left(10,\:0\right)[/tex]
[tex]m=\frac{0-\left(-1\right)}{10-4}[/tex]
[tex]m=\frac{1}{6}[/tex]
We know that the slope-intercept form of the line equation is
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
Using the slope-intercept form to find the y-intercept 'b'
[tex]y = mx+b[/tex]
substituting m = 1/6 and the point (4, -1)
[tex]-1\:=\:\frac{1}{6}\left(4\right)+b[/tex]
[tex]\frac{2}{3}+b=-1[/tex]
subtract 2/3 from both sides
[tex]\frac{2}{3}+b-\frac{2}{3}=-1-\frac{2}{3}[/tex]
[tex]b=-\frac{5}{3}[/tex]
now substituting b = -5/3 and m = 1/6 in the slope-intercept form
[tex]y = mx+b[/tex]
[tex]y\:=\:\frac{1}{6}x+\left(-\frac{5}{3}\right)[/tex]
[tex]y\:=\:\frac{1}{6}x-\frac{5}{3}[/tex]
Therefore, the equation of the line in point-slope will be:
[tex]y\:=\:\frac{1}{6}x-\frac{5}{3}[/tex]

2(s-10)=12
Answer: s = 16
2(s - 10) = 12
distribute the 2
2s - 20 = 12
add 20 to both sides
2s = 32
divide both sides by 2
s = 16
you can then check your work by putting in the 16
2 (16-10) = 12
2 (6) = 12
12 = 12

Evaluate: 4+8÷2x (6-3)
Answer:
hello there
ok so the answer is 4 + [tex]\frac{4}{3x}[/tex]
Step-by-step explanation:
hope this helps!
Answer:
12x+4
Step-by-step explanation:
We can solve this by using PEMDAS (parentheses exponents multiplication division addition subtraction) to solve this in the correct order:
4+8÷2x (6-3)
So first we solve (6-3) since it’s in parentheses:
4+8÷2x (3)
Now we multiply 3 times 8/2x:
4+8/2x(3)
4+12x
(Put in order)
12x+4
And that^ is the answer because we cannot simplify any further!
Hope this helps :)

Answer:
y = ⅔x - 5
Step-by-step explanation:
The line that is parallel to 2x - 3y = 24, would have the same slope as the line, 2x - 3y = 24.
Rewrite;
2x - 3y = 24
-3y = -2x + 24
Divide both sides by -3
y = ⅔x - 8
Thus, the slope of 2x - 3y = 24 is ⅔.
Therefore the line that is parallel to 2x - 3y = 24, will have a slope (m) of ⅔.
Using point-slope form, we can generate an equation that passes through (-3, -7) and is parallel to 2x - 3y = 24.
Thus, substitute (a, b) = (-3, -7) and m = ⅔ into y - b = m(x - a)
Therefore:
y - (-7) = ⅔(x - (-3))
y + 7 = ⅔(x + 3)
Rewrite in slope-intercept form.
Multiply both sides by 3
3(y + 7) = 2(x + 3)
3y + 21 = 2x + 6
3y = 2x + 6 - 21
3y = 2x - 15
Divide both sides by 3
y = ⅔x - 5
