Answer:

14!

Step-by-step explanation:

3(2m-3)=5(m+1)

Step 1: 6m-9 = 5m + 5

Step 2 : Add 9 to -9 and 5

6m= 5m+14

Step 3: Subtract 5m from 6 and 14

Simplify!

m=14

y=4

Step-by-step explanation:

given

DG=GF

10y-4=7y+8

3y-4=8 (subtract both side by 7y)

3y=12 (add both side by 4)

y=12/3

y=4 (ans)

Answer:

18

Step-by-step explanation:

Let number of girls be 'x'.

So, Number of boys = Number of girls - 4

= x - 4

Total number of students in a class = 40

Number of girls + Number of boys = Total number of students in a class

[tex] \longrightarrow [/tex] x + x - 4 = 40

[tex] \longrightarrow [/tex] 2x - 4 = 40

[tex] \longrightarrow [/tex] 2x - 4 + 4 = 40 + 4

[tex] \longrightarrow [/tex] 2x = 44

[tex] \longrightarrow [/tex] [tex] \sf \dfrac{2x}{2} = \dfrac{44}{2} [/tex]

[tex] \longrightarrow [/tex] x = 22

[tex] \therefore [/tex] Number of boys = 22 - 4

= 18

Answer:

B(7 , -2)

Step-by-step explanation:

A(-9 , 6)

Midpoint = (-1 , 2 )

[tex]Midpoint = (\frac{x_{1}+x_{2}}{2} , \frac{y_{1}+y_{2}}{2}) = (-1 , 2)\\[/tex]

                   [tex](\frac{-9+x_{2}}{2},\frac{6+y_{2}}{2}) = (-1 , 2)\\[/tex]

Compare the x co ordinates and y co ordinates,

[tex]\frac{-9+x_{2}}{2}= - 1[/tex]               &    [tex]\frac{6+y_{2}}{2}=2[/tex]

-9 + x₂ = -1*2            & 6 + y₂ = 2*2

-9 + x₂ = -2               & 6 + y₂ = 4

      x₂ = -2 +9          &       y₂  = 4 - 6

      x₂ = 7                 &       y₂   = -2

B(7 , -2)

Answer:

[tex]r = 22.5in[/tex]

Step-by-step explanation:

[tex]d = 2r \\ 45 = 2r \\ \frac{45}{2} = \frac{2r}{2} \\ r = 22.5in[/tex]

Answer:

if the diameter is 45 in the radius would be 22.5 in

Step-by-step explanation:

The radius is half of the diameter.

Answer:

400 meters

Step-by-step explanation:

So it goes 20 meters every second. So you would multiply that by 20 seconds to get 400 meters.

Answer:

B = 160°

Step-by-step explanation:

This is how I solved it (I hope the explanation isn't too confusing):

Since L and K are parallel, I drew a straight line from A to B. By doing this, I'm making a triangle: ΔABC

Then I solved for the angles of the triangle. First, we are given that ∠C = 80° and ∠A = 120°. Although, when I drew the vertical line from A to B, it made a 90° (see attachment).

So what we basically did was break ∠A into two parts: an angle inside ΔABC and one outside. To find the interior angle, simply subtract 90° from 120° to get 30°.

There are 180° in a triangle, so add the two interior angles you know:

30° + 80° = 110°

Then subtract 110° from 180° to find the final interior angle which is:

180° - 110° = 70°.

To find the measure of angle B, you must add all of the parts together, so the 90° outside angle and the 70° interior angle:

90° + 70° = 160°

Answer:

x intercept: (-9,0)

Y intercept: (0,3)

Answer:yes

Step-by-step explanation:0 and 0 means that those numbers dont move that distance apart 1 that 1 X 1 it seems so it would equal 1 2 and 4 2 x 2 = 4 and 3 X 3 equals 9

Step-by-step explanation:

No correlation

Answer:

obtuse and isosceles

Step-by-step explanation:

obtuse bc the third angle is 110 degrees if the two other angles are 35 degrees

if one angle is greater than 90 degrees than it is an obtuse triangle

it's isosceles bc isosceles triangles have two equal sides

Answer:

positive one

Step-by-step explanation:

look at the position on the y axis

Answer:

(0, - 4 )

Step-by-step explanation:

The y- intercept is the value of the y- coordinate where the line crosses the y- axis.

The line crosses the y- axis at y = - 4 ← y- intercept or

(0, - 4 ) in coordinate form

Answer:

Yes, that is unusual as the problem is given.

Step-by-step explanation:

If the mean is 9.5 and the standard deviation is 0.55, then anything within the normal curve of 10.05 on the high end and 8.45 on the low end is normal. 12 is more than several standard deviations or an outlier if this makes sense.

So, it is unusual as the problem is stated, but if it's a weekend, 12 hours is normal. LOL

Good luck!  

Based on the normal distribution parameters given, the probability of a student getting atleast 12 hours of sleep ls 0. Hence, it is abnormal.

Given the Parameters :

Using the Zscore formula, the probability of getting a atleast 12 hours of sleep can be expressed thus :

Zscore = (Score - Mean) / standard deviation

For X ≥ 12 :

The probability using a normal distribution table :

P(Z ≥ 4.54) = 1 - P(Z ≤ 4.54)

P(Z ≤ 4.54) = 1 ( normal distribution table)

P(Z ≥ 4.54) = 1 - 1 = 0

Since, the probability is 0 ; hence, it is unlikely and therefore, abnormal.

Answer:

Write the new equation in slope-intercept form.  Replace the old slope with the new slope.  Replace the y-intercept's value with a variable (b).

Answer:

the perpendicular slope will be the opposite reciprocal of the original slope .

Step-by-step explanation:

example:  lets use the points (5,3) ( 10,7)

                 The slope is 5/4

so we need a line of    -4/5 (perpendicular) that passes through 5,3

Answer:

  x = 14°

  y = 5°

Step-by-step explanation:

Angle COL is complementary to both 25° (∠AOC) and 5y (∠LOM). Then it must be true that ...

  5y = 25°

  y = 5° . . . . . . divide by 5

__

Similarly, angle MOB is complementary to angle LOM, so ...

  90° -25° = 3x +23°

  42° = 3x . . . . . subtract 23° and simplify

  14° = x . . . . . .  divide by 3

The values of x and y are ...
