Answer:
20%
Step-by-step explanation:
Answer:
% of Red CARS = 20%Step-by-step explanation:
Total CARS = 35
Red CARS = 7
% of Red CARS = (red cars ÷ total cars)*100
% of Red CARS = (7÷35)*100
% of Red CARS = 20

Answer:
CD = 4
Step-by-step explanation:
I believe you know the geometric mean for altitudes?
CD = √AD * DB = √8 * 2 = √16 = 4
If you are not aware of this theorem, then use the similarity of triangles.
ADC ~ CDB
AD/DC = CD/DB (cross-multiply)
CD^2 = AD*DB,
CD = √AD * DB = √8 * 2 = √16 = 4

Dave is going to roll a die 60 times and see how often 1 falls.
According to the theoretical probability, how many shots must Dave make to expect to get 1?
Answer:
1,2,3,4,5,6 possibilities, so 1,3,5 are odd. 3/6 probability. consecutive rolls mean multiplication. 3/6 times 3/6 times.... a total of 5 times.
Step-by-step explanation:
Answer:
=1/6 x 60
=10
He should expect about 10 roles to show a 1.
Find f^-1(x) where
f(x) = 3x+2/x
Given:
Consider the function is
[tex]f(x)=\dfrac{3x+2}{x}[/tex]
To find:
The inverse of the function, .i.e., [tex]f^{-1}(x)[/tex].
Solution:
We have,
[tex]f(x)=\dfrac{3x+2}{x}[/tex]
Putting f(x)=y, we get
[tex]x=\dfrac{3y+2}{y}[/tex]
Isolate the variable y.
[tex]xy=3y+2[/tex]
[tex]xy-3y=2[/tex]
[tex]y(x-3)=2[/tex]
[tex]y=\dfrac{2}{x-3}[/tex]
Putting [tex]y=f^{-1}(x)[/tex], we get
[tex]f^{-1}(x)=\dfrac{2}{x-3}[/tex]
Therefore, the inverse function is [tex]f^{-1}(x)=\dfrac{2}{x-3}[/tex].

Given the equation of line y = -2x : Does the point M( 1/2 , 1) belong to the graph?
PLEASE HELP ME! I promise to mark brainliest if you give me the correct answer. Thank you!!
Answer:
no it does not belong to the graph
Step-by-step explanation:
plug in the x-coordinate and see if it gives you the y-coordinate (1). if 1 is what comes out, then it is not a point on the graph.
y = -2(1/2)
y = -1
y = -1 when x = 1/2, which is not 1 so it does not belong to the graph

Answer:
8x²+14x-15
Step-by-step explanation:
that the right answer
Answer:
8x² + 14x - 15
Step-by-step explanation:
(2x + 5)(4x - 3)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(4x - 3) + 5(4x - 3) ← distribute both parenthesis
= 8x² - 6x + 20x - 15 ← collect like terms
= 8x² + 14x - 15

Si colocan en 16 pisos, 16 ladrillos. ¿Cuántos ladrillos pusieron en total?. (expresarlo en forma de potencia)
Answer:
Númer total de ladrillos= 256
Step-by-step explanation:
Dada la siguiente información:
Total de pisos= 16
Total de ladrillos por piso= 16
Para calcular cantidad de ladrillos en total, tenemos que usar la siguiente formula:
Número total de ladrillos= total de ladrillos^2
Número total de ladrillos= 16^2
Númer total de ladrillos= 256
En este caso lo hace al cuadrado por que la cantidad de pisos y ladrillos por piso es la misma. Sino, es mejor expresarlo como una multiplicación.

Find 3 numbers in G.P whose sum is 28 and whose product is 512
Answer:
4, 8 and 16
Step-by-step explanation:
a/r ×a×ar =512
a^3 =512
a = cube root of 512
a=8
8/r+8+8r=28
8r^2+8=20r
8r^2-20r+8=0
8r^2-16r-4r+8=0
8r(r-2)-4(r-2)=0
(8r-4)(r-2)=0
r=2
8r=4
so r=2 or r=1/2
so of r is 2
8/2=4
and 8×2=16
Hello, I need help. thank you
Answer:
B
Step-by-step explanation:
all you need to do is add 5 to the y for example ( -5, 5) add 5 to the (x,5) to make ( -5,10). As you can see only the y value is shifting, not the x value, that's why you need to add 5 to all the y values.
So the answer here is B.
Answer:
B
Step-by-step explanation:
The answer is B because 5 units up from 5 is 10. A and B both have a y coordinate of 5 and the answer letter B is the only one that mention 10 as a y coordinate twice

Step-by-step explanation:
Write the equation of the line in slope-intercept form.
The equation of the line in slope-intercept form is
Answer:
y = -4/3 x + 2
Step-by-step explanation:
Let us assume the equation given is 3y + 4x = 6
The standard form in slope-intercept form is y = mx+c
m is the slope
c is the intercept
Make y the subject of the formula
3y + 4x = 6
3y = -4x + 6
Divide through by 3
3y/3 = -4/3 x + 6/3
y = -4/3 x + 2
Hence the equation of the line in slope-intercept form is y = -4/3 x + 2

The length of a violin string varies indirectly with the frequency of vibrations of the string. When the length is 50 centimeters, the frequency is 2 Hz.
What is the frequency of a string 40 centimeters long?
Answer:
1.6 Hz
Step-by-step explanation:
I know this was posted a week ago, but, if you still need help:
You can set up a proportion, as follows.
50 / 2 = 40 / x => where x = frequency in Hz,
x = 2*40/50 = 80/50 = 8/5 = 1.6 Hz

the directions are: determine whether the triangles are similar by AA, SSS, SAS, or not similar. if the troubles are similar, write a valid similarity statement.
Answer:
The triangles are similar because angle N=angle E and angle F=angle H.
