ii)
Write 2 equations in a and b to represent the information above.
Calculate the cost of a Section A and Section B ticket using the Elimination / Addition
Method.

Answers

ANSWER: a=12 b=15
Explanation: (look at work below)

4a + 1b = 63 (eq1)
5a + 3b = 105 (eq2)
-12a + -3b = -189 (subt. eq1 from eq2)
————————-
-7a = -84
a = 12
4(12) + 1b = 63 (plug in the a value)
48 + 1b = 63
b = 15

Given the function F (x) = x2 -2x -5 determine the average rate of change of the function over the interval -5 < x <6.

Answers

Answer:

Step-by-step explanation:

Here f(x) = x^2 - 2x - 5, which at x - -5 is 25 +10 - 5 = 30 and at x = 6 is 19.

The average value of a function f(x) over an interval [a, b] is

f(b) - f(a)

ave. val. = ---------------

b - a

which in this particular case is

19 - 30

ave. val. = ----------------- = -11/11 = 1

6 - (-5)

The average value of this function f(x) = x^2 - 2x - 5 on [-5, 6] is 1.

EMERGENCY HELP PLS: The state decided that the angle a wheelchair ramp
makes with the ground should be no more than 4.3º.
a) What is the maximum height of a 25-foot ramp? Round to the nearest tenth of a foot.
b) What distance along the ground would this ramp
cover? Round to the nearest tenth of a foot.
Maximum height = ? ft.
Distance along the ground ? ft.

Answers

Answer:

1.9 feets (nearest tenth) ;

24.9 feets

Step-by-step explanation:

Given that :

Angle, θ = 4.3°

Length of ramp = 25

Maximum Height, h ;

sinθ = opposite / hypotenus

Sin 4.3 = h / 25

0.0749787 * 25 = h

1.874 feet = h

1.9 feets (nearest tenth)

Distance along the ground the ramp could cover :

Cos θ = Adjacent / hypotenus

Cos 4.3 = x / 25

0.9971851 = x / 25

0.9971851 * 25 = x

x = 24.929

x = 24.9 (nearest tenth)

The measures of the three angles of a triangle are given by x+4,x, and 2x. What is the value of x

Answers

Answer:

x = 44°

Step-by-step explanation:

The sum of all the interior angles of a triangle = 180°

so:

(x+4) + x + 2x = 180°

reducing:

4x + 4° = 180°

4x = 176°

x = 44°

Jack bought 4 hot dogs and 3 sodas for $15.50. Mack bought 3 hot dogs and 2 sodas for $11.25. Find the cost of each.

Answers

Answer:

Hot dogs: $2.75

Sodas: $1.5

Step-by-step explanation:

Hot dogs = x

Sodas = y

4x + 3y = 15.5

3x + 2y = 11.25

First find the value of the hot dogs by canceling out y:

2(4x + 3y) = 2(15.5)

3(3x + 2y) = 3(11.25)

= 8x + 6y = 31

9x + 6y = 33.75

x = $2.75 (Minus bottom equation from the top to isolate x)

Plug in for x to get y:

3(2.75) + 2y = 11.25

2y = 11.25 - 8.25 (Isolate the y)

2y = 3

y = 3/2, or $1.5

Ed bought 4 pieces of salmon weighing a total of 2 kilograms. One piece weighed 4/10 kg, and two of the pieces weighed 5/10 kg each. What was the weight of the fourth piece of salmon? Explained

Answers

Answer:

6/10 kg

Step-by-step explanation:

Ed bought 4 pieces of salmon weighing a total of 2 kilograms. One piece weighed 4/10 kg, and two of the pieces weighed 5/10 kg each. What was the weight of the fourth piece of salmon? Explained

Hence:

Total kg of salmon = 4/10 + 5/10 + 5/10 + fourth piece

Total kg = 2 kg

Hence,

Fourth piece = 2 kg - ( 4/10 + 5/10 + 5/10) kg

Lowest common denominator = 10

2 kg - (4 + 5 + 5/10)

2kg - (14/10)kg

2 kg - 1 4/10 kg

= 6/10 kg

The weight of the fourth piece =

Answers

x = 31

180 = 3x + 25 + 2x
180 = 5x + 25
-25. -25
155 = 5x
x = 31

Answer:

x=31

Step-by-step explanation:

Hello there!

the shown angles are supplementary meaning that the sum of the two is 180

so we create an equation

180=3x+25+2x

step 1 combine like terms

3x+2x

now we have

180=25+5x

step 2 subtract 25 from each side

180-25=155

now we have

155=5x

step 3 divide each side by 5

155/5=31

5x/5=x

we're left with x=31

solve the system of linear equations by substitution

Answers

Answer:

(-4, 5)

Step-by-step explanation (work shown in attached picture):

1) Since x is already isolated in the first equation, substitute that value for x into the other equation to find y. So, substitute 16-4y for the x in 3x + 4y = 8, then solve for y. This gives us y = 5.

2) Now, substitute that given value for y back into any one of the equations to find x. I chose to do it in the first equation. Substitute 5 for the y in x = 16-4y, then solve for x this time. This gives us x = -4.

Since x = -4 and y = 5, the solution is (-4, 5).

Answer:

Value of x is -4 Value of y is 5

When I was a grant writer, if I sent an email like that, I would have been in my boss's office so fast. SO let's learn proper etiquette for sending emails. 1) Start with a salutation. Hello, Hi, Dear _____, Hi _______, Greetings! any of these work. Make sure your initial email has these. If you don't know the person personally, use Mr., Mrs., Ms., or the new Mx. and their last name. 2) Body: The body has to be right to the point and formal. Most work emails are all business. You can say something like "I hope your Monday is going well!" but beyond that, get to the point. 3) End it well. Best is a good way to go if you don't know the person. Sincerely is good too. It's all personal preference. Just make sure you end it. Also, ALWAYS include your last name. I get so many emails that say "Jackie" or whatever short name people go with, and I have 5 classes.
