Answer:
They'll meet after 200 meters , if they simultaneously start running towards each other.
Step-by-step explanation:
Let x =distance travelled by dog and 200-x be the distance travelled by cat. Inorder to meet, the sum of their travelled distances shall be equal to 200 meters as they are far apart by 200 meters.
Dog: Distance =Speed x time: x=30t
Cat: Distance = 200-x
=24t
The sum of their distance travelled shall be 200 meters: 30t+ 24t= 200;54t=200;t=200/54=3.7secs
So they will meet after 3.7 seconds
To check:
Distance travelled by dog :x=30(3.7)
=111.11 meters
Distance travelled by cat: 24t=24(3.7)
=88.89 meters
Therefore since they are travelling towards each other and their distance apart is 200 meters, after 3.7 seconds they will meet because dog travelled 111.11 meters and cat travelled 88.89 meters and they covered already 200 meters as the sum of 111.11+ 88.89
=200 meters
If a wave has a wavelength of 0.5 m and a frequency of 2134 Hz, what is its speed? *SHOW ALL 4 STEPS.
wave length= 0.5 m
frequency= 2134 Hz
to find:the speed
solution:[tex]v = f \gamma [/tex]
[tex]v = velocity[/tex]
[tex]f = frequency[/tex]
[tex] \gamma = wave \: length[/tex]
[tex]v = 2134 \times 0.5[/tex]
[tex]v = 1067s[/tex]
hence, the speed of the wave is 1067s.
Which equation can be used to solve for the measure of angle abc? tan(x) = startfraction 2.4 over 10 endfraction tan(x) = startfraction 10 over 2.4 endfraction sin(x) = startfraction 10 over 10.3 endfraction sin(x) = startfraction 10.3 over 10 endfraction
The equation can be used to solve for the measure of angle abc is sinx = 2.4/10.3
SOH CAH TOA identityThe identity is used to find the measure of sides and acute angles of a right triangle
From the diagram shown, <ABC is the reference abgle hence;
Opposite side = 2,4cm
Hypotenuse .=10.3cm
According to the identity
sin x = opp/hyp
sinx = 2.4/10.3
sinx = 0.233
x = 13.47 degrees

In an AP* Stats class, 57% of students eat breakfast in the morning and 80% of students floss their teeth. Forty-six percent of students eat breakfast and also floss their teeth. What is the probability that a student from this class eats breakfast but does not floss their teeth
Answer:
The probability that a student from this class eats breakfast but does not floss their teeth is .11 (11%).
Step-by-step explanation:
Let's start by making a two-way table (you can also make a tree diagram).
Let's make the total number of students = 100. Now, fill out the table using the given probabilities from the question.
We are given that 57% of students eat breakfast in the morning, so the total in the "Eats breakfast" column is 57.
80% of the students floss their teeth, so the total in the "Flosses teeth" row is 80.
We can fill out the rest of the table using simple algebra and the fact that the probabilities must add up to 1.
I've attached a table that I created showing what the two-way table should look like when filled out completely.
Now, we want to find the probability that a student eats breakfast but does not floss their teeth.
We can look at the column "Eats breakfast" and the row "Does not floss teeth" and see that 11 (out of 100) students eat breakfast without flossing their teeth.
Therefore, the probability that a student from this class eats breakfast without flossing their teeth is .11.

What is the value of x?
Enter your answer in the box.
x =
Answer:
x = 39
Step-by-step explanation:
all triangles have angle measures that add up to 180°.
This means that to find what x is, you add 102 and 39, and then subtract that from 180, so
180-(102+39) = x
180-141=x
39=x
Answer:
x° = 39°
Step-by-step explanation:
According to the angle sum property of triangles, the 3 angles in a triangle will sum up to 180°.
102° + 39° + x° = 180°
141° + x° = 180°
x° = 180° - 141°
x° = 39°

The area of a circle is 9π ft What is the circumference, in feet? Express your answer in terms of \piπ. (pi)
Answer:
6×pi ft
Step-by-step explanation:
the area of a circle is
pi × r²
with r being the radius of the circle.
so,
9×pi = r² × pi
9 = r²
r = 3 ft
the circumference of a circle is
2×pi× r
that means in our case it is
2×pi×3 = 6×pi ft

The second one you have to choose GREATER THAN, LESS THAN, OR EQUAL TO
Answer:
what is intercept: intercept simply means a point on the y axis through which a slope passes and also in the equation you were given y = mx + c I mean y = 2x -2 the c is the intercept meaning -2 .
so wherever that straight line meets with with y axis the number at that very point is your intercept.
the y intercept for the first one is -2
and it's "less than" since it's a negative number.

A solution to -x + 10 = 2x + 4 is 8
Answer:
False.
Step-by-step explanation:
What is the question if you have the solution already?
I guess its a true/false question. In that case it's false because:
-x + 10 = 2x + 4
-x -2x + 10 = 4
-x - 2x = 4 - 10
-3x = -6
x = - 6 / -3
x = 2
Answer:
False.
This equation has only one solution, and it is x = 2.
Step-by-step explanation:
-x + 10 = 2x + 4
Subtract 2x from both sides.
-3x + 10 = 4
Subtract 10 from both sides.
-3x = -6
Divide both sides by -3.
x = 2
False.

The price of a computer is marked down from $550 to $484 for a sale. The

$124.08
B $132.00
D
$58.08
Answer:
A) $425.92
Step-by-step explanation:
The new price percentage with relation to the previous can be determined by dividing [tex]p = \frac{484}{550}[/tex]. Once we calculate p, we can multiply it by 484, which is equivalent to applying the same discount, thus [tex]\frac{484}{550}484=425.92[/tex]
