Find an equation of the line perpendicular to y = -1/2x – 3 that crosses the point
(-3, -2). Write your equation in slope-intercept form.

Answer:

18.73

Step-by-step explanation:

6 x 0.25 = $1.50

2.99 x 2 = $5.98

3.75 x 3 = $11.25

11.25+5.98+1.50 = 18.73

Answer:

126

Step-by-step explanation:

112 plus 14 equals to 126

they ate 126 pizzas all together

Answer:

The first choice (12)

Step-by-step explanation:

i'm not 100% what the theory is but here is how I did it:

the angle D and 115% are supplementary which means they add up to 180.

115+x=180

x=65

so now that you know all the angle measures, you also know that all angles of a triangle add up to 180.

65+3x+19+5x=180

combine like terms:

8x+84=180

subtract 84 from both sides:

8x=96

divide by 8 on both sides

x=12

Answer:

k = 4

Step-by-step explanation:

7k - 6 = 2k + 14

(7k - 2k) - 6 = (2k - 2k) + 14

5k - 6 = 14

5k (- 6 + 6) = 14 + 6

5k = 20

5k/5 = 20/5

k = 4

Answer:

C. The mapping represents a relation but not a function

Step-by-step explanation:

✔️The relation is a function because every input value (domain) is mapped to exactly one output value (range). So option A is TRUE.

✔️The range consist of 2 and 1 (output values).

Option B is TRUE

✔️In the domain (input value), we have 3, 6, 7.

Option D is TRUE

Only option C is NOT TRUE.

Answer:

7[tex]\frac{1}{2}[/tex] rows

Step-by-step explanation:

just count the rows! (if she planted half a row then add it as half)

2[tex]\frac{1}{2}[/tex] + 2[tex]\frac{1}{2}[/tex] + 2[tex]\frac{1}{2}[/tex] (you can split it up)

2 + 2 + 2 + [tex]\frac{1}{2}[/tex] + [tex]\frac{1}{2}[/tex] + [tex]\frac{1}{2}[/tex]

6 + 1[tex]\frac{1}{2}[/tex] = 7[tex]\frac{1}{2}[/tex]

Answer:

A. (3, -1)

Step-by-step explanation:

The ordered pair that is a solution is the one which makes the inequality TRUE when the value of the ordered pairs are plugged into 4x - 3y < 16

Therefore, the ordered pair, (3, -1) is the solution because it is the only given ordered pair in the options that makes the inequality true. Thus:

Substitute x = 3 and y = -1 into 4x - 3y < 16

4(3) - 3(-1) < 16

12 + 3 < 16

15 < 16 (TRUE)

Answer:

x=-6

Step-by-step explanation:

3x+4=2

3x=2-4

x=-2*6

x=-6

Answer:

v ≈ 8.5 km/h

Step-by-step explanation:

Since the diameter of the wheel is 3 m the radius will be r = 1.5 m.

Use the radius of the water wheel to find it's circumference C:

[tex]C=2\pi r[/tex]                                               [set r = 1.5 m]

⇒ [tex]C=2\pi (1.5)[/tex]

⇒ [tex]C=3\pi[/tex] m

One revolution of the water wheel corresponds to [tex]3\pi[/tex] meters so the angular velocity 15 rmp (revolutions per minute) corresponds to:

[tex]15(3\pi )[/tex] = [tex]45\pi[/tex] [tex]m[/tex]/min

Using this result, the speed of the river in kilometers per hour will be:

[tex]v=\frac{45\pi m }{1 min}[/tex] ×  [tex]\frac{1 km}{1000 m}[/tex] × [tex]\frac{60 min}{1 h}[/tex]

⇒ [tex]v=8.48230016469[/tex]  [tex]km/h[/tex]

⇒ [tex]v[/tex] ≈ [tex]8.5[/tex] km/h

Answer:

≈ 8 km per hour

Step-by-step explanation:

C = [tex]\pi[/tex] d

C = [tex]\frac{66}{7}[/tex]

Velocity = [tex]\frac{66}{7}[/tex] × 15 = [tex]\frac{990}{7}[/tex] ( meters per minute ) = [tex]\frac{0.99}{7}[/tex] × 60 ≈ 8.5 km/h

Answer: An acute angle

Step-by-step explanation: An acute angle is an angle that measures 89 degrees or less (Less than 90 degrees). Another way to define acute angles is any angle that is smaller than a right angle.

Answer:

You find the area of all the faces of the square pyramid, then add them together to get the surface area.

Answer:

6/28 or 0.214

Step-by-step explanation:

6/7÷4=6/7÷4/1

6/7÷4/1=6/7×1/4

6/7×1/4=6/28

Not sure if you're allowed to leave it in a fraction or not, so as a decimal, it's 0.214 to 3 s.f.

Hope this helps :-)

Step-by-step explanation:

You are given the information about the angles under the line given.

Answer:

[tex]\frac{w}{5}=6[/tex]

Step-by-step explanation:

The first part indicates division with the phrase, divided by.

A number w divided by 5 - [tex]\frac{w}{5}[/tex]

Equals '6' would indicate that the value of 'w' and '5' would be '6'.

Equals 6 - [tex]= 6[/tex]
