Answer:

B. 30

Step-by-step explanation:

A line is 180 degrees, so when we have 100, we subtract that from 180 to get the interior angle of 80.

A triangle has a sum of 180, so we just subtract 80 and 70 from 180 to get 30.

Hope this helps

Answer:

∠EFG = 48°

Step-by-step explanation:

As FH bisects ∠EFG , ∠EFH = ∠HFG .

We know that ∠EFH = (-5x + 89)° . So ∠HFG = ∠EFH = (-5x + 89)°

Also, ∠HFG  + ∠EFH = ∠EFG

=> 2(-5x + 89)° = (61 - x)°

=> -10x + 178 = 61 - x

=> 10x - x = 178 - 61

=> 9x = 117

=> x = 117 / 9 = 13

Putting the value of 'x' in ∠EFG gives :-

(61 - x)° = (61 - 13)° = 48°

Use the linear combination method to solve the system of equations. Explain each step of your solution. 2x-3y=13 4x-y=-9
Tems11 [23]

2x -3y = 13

4x -y = -9

Multiply the second equation by -3 to make the coefficient of Y opposite the first equation.

4x -y = -9 x -3 = -12x + 3y = 27

Now add this to the first equation:

2x -12x = -10x

-3y +3y = 0

13 +27 = 40

Now you have :

-10x = 40

Divide each side by -10:

x = 40 / -10

x = -4

Now you have a value for x, replace that into the first equation and solve for y:

2(-4) - 3y = 13

-8 - 3y = 13

Add 8 to both sides:

-3y = 21

Divide both sides by -3:

y = 21/-3

y = -7

Now you have X = -4 and y = -7

(-4,-7)

ANSWER PLEASE I WILL MARK AS BRAINLIEST
ICE Princess25 [194]

Answer:

162 mL  

Step-by-step explanation:

1.Convert all volumes to millilitres

(a) Chlorpheniramine

V = 100 mL

(b) Lidocaine

V = \text{2 fl oz} \times \dfrac{\text{29.57 mL}}{\text{1 fl oz}} = \textbf{59 mL}

(c) Banana flavouring

V = \dfrac{1}{2}\text{ tsp} \times \dfrac{\text{4.928 mL}}{\text{1 tsp}} = \textbf{2.5 mL}

2.Calculate the total volume

Chlorpheniramine =  100  mL

Lidocaine               =   59

Banana flavouring = <u>    2.5  </u>    

TOTAL                    = 162 mL

HELP ME IM SO CONFUSED
givi [52]

Answer:

  • 1) 4812 students
  • 2) 763 pounds
  • 3) $30906.76

Step-by-step explanation:

1)

  • Initial number = 2988
  • Rate of increase = 10%

<u>Number of students after 6 years:</u>

  • a_6 = 2988(1+0.1)^{6-1} = 4812

2)

  • Initial number = 1200
  • Rate of decrease = 14%

<u>Amount of gold after 4 years:</u>

  • a_4=1200(1-0.14)^3 = 763

3)

  • Initial number = 28000
  • Rate of increase = 2.5%

a)

<u>Salary after n years:</u>

  • a_n=28000(1+0.025)^{n-1} = 28000*1.025^{n-1}

b)

<u>Salary in the 5th year:</u>

  • a_5=28000*1.025^4 = 30906.76
