Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (- 2, - 4) and (x₂, y₂ ) = (6, 11)

d = [tex]\sqrt{(6+2)^2+(11+4)^2}[/tex]

   = [tex]\sqrt{8^2+15^2}[/tex]

   = [tex]\sqrt{64+225}[/tex]

   = [tex]\sqrt{289}[/tex]

   = 17 → A

Answer:

4) 3.5

5) -1.375

Step-by-step explanation:

plug in x for the missing number and solve

Answer:  

4. 12 (3.5) -15 = 27

5. -18 (445.5) -¾ = 24

Step-by-step explanation:

4. 12? -15 = 27

         12? = 42

             ? = 3.5

5. -18? -¾ = 24

         -18? = 24 + 3/4

          -18? = 96/4 + 3/4

         -18? = 99/4

              ? =  891/2  or 445.5

Answer:

A = 18 cm²

Step-by-step explanation:

The volume (V) of a prism is calculated as

V = area of base (A) × height

Here V = 216 cm³ and h = 12 cm , then

A × 12 = 216 ( divide both sides by 12 )

A = 18 cm² ← area of base

Answer:

2070 people.

Step-by-step explanation:

We can set up the following proportion:

[tex]\frac{46}{100}=\frac{x}{4500}[/tex]

Then, cross multiply, and you'll get your answer: 2070 people.

Hope this helped!

Answer:

2,070 people

Step-by-step explanation:

46% of 4,500 is 2,070

you can also solve this by doing 4,500 x .46 which will also give you 2,070

hope this helps :)

Answer:

(11+12+17)x = 40x.

Step-by-step explanation:

Rs 3520 is divided in the Ratio 11:12:17 as Rs 968, Rs 1056, Rs 1496. According to the question, we have to divide Rs 3520 in the ratio 11:12:17. Let the common ratio be x. So, total share = (11+12+17)x = 40x.

Step-by-step explanation:

12:15 = 4:5

Answer: 9

Step-by-step explanation:

12 + 8 + 7 + 12 + 6 = 45

There are 5 numbers

45 / 5 = 9

Answer:

mean = 9

Step-by-step explanation:

The mean is calculated as

mean = [tex]\frac{sum}{count}[/tex] , then

mean = [tex]\frac{12+8+7+12+6}{5}[/tex] = [tex]\frac{45}{5}[/tex] = 9

Answer:

Step-by-step explanation:

If they are vertical angles, they are opposite to each other where two lines intersect. Vertical angles are equal to each other so

5x-15=3x+1

2x-15=1

2x=16

x=8 degrees.

The angles are

a=5x-15, and x=8 so

a=5(8)-15

a=40-15

a=25 degrees.

Answer:

$12

Step-by-step explanation:

$10 is   100% of the price

 The selling price is 120% of the price

x= selling price

10 -------------100%

x ----------------120 %

Cross multiplication

10x120 = 100x

1200 = 100x

Divide both sides by 100

12 = x

 Selling  price = $12

Answer:1.5

1st box: 0.75

2nd box: 1.5

3rd box: 3

4th box: 28

Step-by-step explanation:

First I got the 4th box. I found out 3.5x2=7, and 7x2=14. So I know the pattern is multiply by 2.

Then I got the 3rd box. I used a proportion. (14x6)/28= 3

Then the 2nd box. I did (3x7)/14=1.5

Lastly, I did the 1st box. (1.5x3.5)/7= 0.75

I hope that helped :)

Answer:

1 1/12inches

Step-by-step explanation:

Given

Length = 1/6 inches

Width = 3/8 inches

Perimeter of the rectangle = 2 (Length + Width)

substitute

P = 2(1/6 + 3/8)

P = 2(4+9/24)

P=  2(13/24)

P = 26/24

P = 1 2/24

P = 1 1/12inches

hence the perimeter of the triangle is 1 1/12inches

Answer:

SAS theorem

Step-by-step explanation:

Given

[tex]\square ABCD[/tex]

[tex]\[ \lvert \[ \lvert AB =\[ \lvert \[ \lvert CD[/tex]

[tex]\angle BAC = \angle DCA[/tex]

Required

Which theorem shows △ABE ≅ △CDE.

From the question, we understand that:

AC and BD intersects at E.

This implies that:

[tex]\[ \lvert \[ \lvert AE = \[ \lvert \[ \lvert EC[/tex]

and

[tex]\[ \lvert \[ \lvert BE = \[ \lvert \[ \lvert ED[/tex]

So, the congruent sides and angles of △ABE and △CDE are:

[tex]\[ \lvert \[ \lvert AB =\[ \lvert \[ \lvert CD[/tex] ---- S

[tex]\angle BAC = \angle DCA[/tex] ---- A

[tex]\[ \lvert \[ \lvert BE = \[ \lvert \[ \lvert ED[/tex] or [tex]\[ \lvert \[ \lvert AE = \[ \lvert \[ \lvert EC[/tex]  --- S

Hence, the theorem that compares both triangles is the SAS theorem

Answer:

Step-by-step explanation:

it is hard to know exactly by eye balling the graph  I can't dissern the y intercept it might be 4.5 but it could be 4.33, but it looks for sure like the x intercept equals 6 but does it

the dots on the line are at (-2, -6) and (2, 3)  so we can find the slope m

in the y = mx + b line equation   b is the y intercept

m = Δy/Δx     =  (y1 - y2) / (x1 - x2)

                     =  (-6 - -3) /  (-2 - 2)

                     =     -3 / -4

                 m = 3/4

       y = 3x/4  +  y intercept     which i can't dissern (read directly from the

                                                  graph, but we believe y = 0   when x is six

       0 = 3(6)/4  + y intercept

       -18/4 = 18/4 -18/4  + y intercept

        -9/2 = y intercept

        -4.5 = y intercept

   y = 3x/4 - 9/2          i think exact number means NO FRACTIONS but that is whole number so let me gaggle it  What are exact numbers?  Gaggle indicates exact numbers are integers   example  3 ft in a yard 12 eggs in a dozen

    y = 3x/4 - 9/2               multiple both sides by 4

   4y = 3x  - 36/2

   4y = 3x - 18    <------------------  FINAL ANSWER
