please correct me if I am wrong, as I have not done this in a while.      

Step-by-step explanation:

I used the formula (y2-y1)/ (x2-x1)

Answer:

A= 100+20h B=40h

Step-by-step explanation:

A=100+20h

B= 40h

Answer:

For company A:

100 + (20h)

OR

100 + (20 x h)

For company B:

40h

OR

40 x h

Step-by-step explanation:

For company A, you are multiplying 20 by h because you must pay $20 per hour. Then, you have to add 100 to that because there is a $100 dollar rental fee.

For company B, you are multiplying 40 by h because you must pay $40 per hour. There is no rental fee, so that means you don't have to add anything.

Hope this helps!

Step-by-step explanation:

Answer:

{x,y} = {67/16,-15/4}

Step-by-step explanation:

// Solve equation [2] for the variable  y

 [2]    2y = -8x + 26

 [2]    y = -4x + 13

// Plug this in for variable  y  in equation [1]

  [1]    4x + 5•(-4x+13) = -2

  [1]    -16x = -67

// Solve equation [1] for the variable  x

  [1]    16x = 67

  [1]    x = 67/16

// By now we know this much :

   x = 67/16

   y = -4x+13

// Use the  x  value to solve for  y

   y = -4(67/16)+13 = -15/4

Answer:

The new pressure P₂  is 3.3 atm

Step-by-step explanation:

Pressure of gas = 2.7 atm

Volume = 3.6 L

Temperature = 324 K

Now we are given that  volume of the gas is kept constant.

Temperature is increased to 396 K

We need to find the pressure.

The formula used is: [tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]

We have P₁ = 2.7

T₁ = 324 K

T₂ = 396 K

P₂ = ?

Putting values in the formula and finding P₂

[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}\\\frac{2.7}{324}=\frac{P_2}{396}\\P_2=\frac{2.7}{324}\times 396\\P_2=0.0083 \times 396\\P_2=3.3[/tex]

So, the new pressure P₂  is 3.3 atm

Answer:

Replacing x = 1 in the equation above, we have: (4x1) + 22 = 13

=> 5 +22 = 13 => 27 [tex]\neq[/tex] 13

So 27 is not equal to 13 => x=1 is not a solution to 4x+22 = 13.

Answer:

429 058 people

Step-by-step explanation:

We will use the population growth formula.

Initial population * e ^ (rate * time)

With the information given, the equation will look like this:

[tex]330000 * e^(0.0375*7)[/tex]

(The numbers in the parantheses are exponents.)

Plug this into the calculator and you will get:

Answer:

The measures of those two angles are 60° and 220°

Step-by-step explanation:

Let us solve the question

∵ A quadrilateral has two angles that measure 10° and 70°

→ By using the rule above, subtract their measure from 360

∴ The sum of the other two angles = 360° - 10° - 70°

∴ The sum of the other two angles = 280°

∵ The other two angles are in a ratio of 3: 11

→ Find the sum of the parts of the ratio

∵ The sum of the parts of the ratio = 3 + 11 = 14

∵ The sum of the measures of these 2 angles is 280°

→ By using the ratio method

→ m∠1 : m∠2   :  their sum

→ 3      :  11       :  14

→ x      :  y        :  280°

→ By using cross multiplication

∵ x × 14 = 3 × 280

∴ 14x = 840

→ Divide both sides by 14

∴ x = 60

∴ m∠1 = 60°

∵ y x 14 = 11 x 280

∴ 14y = 3080

→ Divide both sides by 14

∴ y = 220

∴ m∠2 = 220°

∴ The measures of those two angles are 60° and 220°

Answer:

24°

Step-by-step explanation:

Let's represent the unknown angle with x

So ;

66+x=90

x=90-66

x=24°

Therefore 24° is the missing angle.

Answer:

24°

Step-by-step explanation:

The missing angle is 90-66 = 24°.

1/3 x 27 = 9

Answer:

1200 beds

Step-by-step explanation:

Shelter A has a capacity of 300 beds and is 60% occupied.

The amount of beds occupied =

60% × 300 beds

= 60/100 × 300

= 180 beds

Shelter B is 30% occupied.

Let the number of beds in Shelter B = x

30% × x = 0.30x beds

Hence:

180 beds + 0.30x beds

The ratio of the occupancy of Shelter A to Shelter B is 1 : 2.

Let the sum of the proportion = 1 + 2 = 3

Hence:

Number of beds in Shelter B =

2/3(180 beds + 0.30x beds) = 0.3x

2/3(180 + 0.30x) = 0.3x

Cross Multiply

2(180 + 0.30x) = 0.3x × 3

360 + 0.6x = 0.9x

Collect like terms

360 = 0.9x - 0.6x

360 = 0.3x

x = 360/0.3

x = 1200 beds

Therefore, the number of beds that are in Shelter B is 1200 beds

Answer:

2x+12=22

Step-by-step explanation:

the side we don't know is x and there are 2 and there are 2 lengths the same in a rectangle. we know one of them and it is 6 so we do 6 x 2 which is 12.

Answer:

2x + 24

Step-by-step explanation:

The product of 2 and a number is: 2x

because product means multiply. 2 and a number means 2 times an unspecified number represented as x. 24 more than that product just means to add 24 to the product of 2x.

Answer:2x + 24
