which of the following is true?

1 plus 1 equals 4

18 minus 2 is 4

13 plus 5 equals 9

10 minus 11 is -1

Answer:

Step-by-step explanation:

1) a) 15x =  12x + 15          {Alternate interior angles}

b) 15x - 12x = 15             {Subtract 12x from both sides}

       3x  = 15

        x = 15/3

x = 5

c) Alternate interior angles

2) a) 3x + 10 + 3x - 28 = 180  {co- interior angles are supplementary}

b) 6x  - 18 = 180      { Combine like terms}

        6x   = 180 + 18

         6x  = 198

          x = 198/6

         x = 33

c) co- interior angles are supplementary

3) a) 7x + 9 + 5x +3 = 180

  b) 12x + 12 = 180

      12x    = 180 - 12

          12x = 168

             x = 168/12

           x = 14

c) linear pair

4) a) 12x - 18 = 8x + 10

b) 12x - 8x - 18 = 10

           4x - 18  = 10

                   4x = 10 +18

                   4x = 28

                     x = 28/4

x = 7

c) Vertically opposite angles are equal.

Answer:

you will have to pay a total of 54$

Step-by-step explanation:

50$ : 100% = x : 108% (+8% for the tax   100+8+108)

100x = 108 x 50

100x = 5400

5400 ÷ 100 = 54

Total 54 $

The total money paid to buy a coffee maker is $54.

Given that, the cost of a coffee maker=$50 and the sales tax=8%.

We need to find the total cost of a coffee maker.

A sales tax is a tax paid to a governing body for the sales of certain goods and services. Usually, laws allow the seller to collect funds for the tax from the consumer at the point of purchase.

Sales tax is an amount of money, calculated as a percentage, that is added to the cost of a product or service when purchased by a consumer at retail.

Now, the total money paid=50+8% of 508% of 50 can be calculated as 0.08×50=4

So, 50+4=$54

Therefore, the total money paid to buy a coffee maker is $54.

Answer: 17

Step-by-step explanation: 15 squared plus 8 squared equals the square root of 289 which is equal to 17 because 17 squared is... 289

Answer:

17

Step-by-step explanation:

We do a^2+b^2=c^2,

8^2+15^2=c^2

64+225=289

Square root of 289 = 17

c=17

Answer:

r = 8

Step-by-step explanation:

Given that M is directly proportional to r² then the equation relating them is

M = kr² ← k is the constant of proportionality

To find k use the condition when r = 2 , M = 14

k = [tex]\frac{m}{r^{2} }[/tex] =[tex]\frac{14}{4}[/tex]  = [tex]\frac{7}{2}[/tex]

M = r² ← equation of proportion

When M = 224, then

224 =[tex]\frac{7}{2}[/tex]r² ← multiply both sides by 2

7r² = 448 ( divide both sides by 7 )

r² = 64 ( take the square root of both sides )

r = [tex]\sqrt{64}[/tex] = 8

Answer:

It would be 7 miles away.

Step-by-step explanation:

I think.

Jack's home is 5 miles away from the school.

Important information:

According to the Pythagoras Theorem:

[tex]\text{Hypotenuse}^2=\text{Perpendicular}^2+\text{Base}^2[/tex]

Jack goes 4 miles north and 3 miles east. It forms a right triangle with legs 4 miles and 3 miles, and we have to find the hypotenuse to get the distance between his school and home.

Using the Pythagoras Theorem, we get

[tex]\text{Hypotenuse}^2=(3)^2+(4)^2[/tex]

[tex]\text{Hypotenuse}^2=9+16[/tex]

[tex]\text{Hypotenuse}=\sqrt{25}[/tex]

[tex]\text{Hypotenuse}=5[/tex]

Therefore, Jack's home is 5 miles away from the school.

Answer:

the comedy films, action and horror is 14, 49 and 7 respectively

Step-by-step explanation:

The computation of each one dvds is as follows;

Total dvds is 70

Now the ratio of comedy films to action to horror is 2:7:1

So the total of 10

Now the each one dvds is

For comedy flms

= 70 × 2 ÷ 10

= 14

For actions

= 70 × 7 ÷ 10

= 49

For horror

= 70 × 1 ÷ 10

= 7

Hence the comedy films, action and horror is 14, 49 and 7 respectively

FH is half of CG

Answer:

x=14

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−1/5(x−4)=−2

(−1/5)(x)+(−1/5)(−4)=−2(Distribute)

−1/5x+4/5=−2

Step 2: Subtract 4/5 from both sides.

−1/5x+4/5−4/5=−2−4/5

−1/5x=−14/5

Step 3: Multiply both sides by 5/(-1).

(5/−1)*(−1/5x)=(5/−1)*(−14/5)

Answer:

(x , y) = (2 , 1)

Step-by-step explanation:

// Solve equation [1] for the variable x

[1] x = -4y + 6

// Plug this in for variable x in equation [2]

[2] -(-4y+6) - 2y = -4

[2] 2y = 2

// Solve equation [2] for the variable y

[2] 2y = 2

[2] y = 1

// By now we know this much :

x = -4y+6

y = 1

// Use the y value to solve for x

x = -4(1)+6 = 2

Answer:

[tex]\frac{F}{36}, \frac{F}{28} ,\frac{F}{20}[/tex] respectively

Step-by-step explanation:

From the question we are told that

Facility A =36 pieces/box

Facility B =28 pieces/box

Facility C =20 pieces/box

Let the Fruit received be F

Generally the Facility A's number of boxes is mathematically given by

[tex]36 pieces=1 box[/tex]

Total Pieces=F

Therefore

Facility A's total amount of box = F/36

Generally the Facility B's number of boxes is mathematically given by

[tex]28pieces=1box[/tex]

Therefore

Facility B's total amount of box = F/28

Generally the Facility C's number of boxes is mathematically given by

[tex]20pieces=1box[/tex]

Therefore

Facility C's total amount of box = F/20

Therefore

Each Facility will make us of [tex]\frac{F}{36}, \frac{F}{28} ,\frac{F}{20}[/tex] respectively in packing there allocated Fruit.
