What’s the answer ?? The triangle says 84 degrees

Answer:

Step-by-step explanation:

If 2a+3b gives the cost (in dollars) for a shirts and b pairs of pants at a garage sale

a) To get cost for 1 shirt and the cost for 1 pair of pants, we will substitute a = 1 abd b = 2 into the expression given

Cost = 2(1) + 3(2)

Cost = 2 + 6

Cost = $8

Hence cost for 1 shirt and the cost for 1 pair of pants is $8

b) For the total cost for 5 shirts and 5 pairs of pants;

a = 5 and b= 5

Cost = 2(5)+3(5)

Cost = 10 + 15

Cost = $25

Hence the total cost for 5 shirts and 5 pairs of pants is $25

c) To check whether $20 will be enough to buy 7 shirts and 2 pairs of pants, we will substitute a =  7 and b = 2 into the expression;

Cost = 2(7)+3(2)

Cost = 14 + 6

Cost = $20

Hence $20 will be enough to buy 7 shirts and 2 pairs of pants

Answer:

the square root of 20 could be between 4 and 5 OR -4 and -5.

Step-by-step explanation:

plus or minus 4 squared is 16 and plus or minus 5 squared is 25. finally, 20 is between 16 and 25.

Answer:

Step-by-step explanation:

Cost ≤ per day amount + daily mileage amount.   * miles

75 ≥ 30 + daily mileage amount * miles

That's as far as I can take you. Two other equations are impossible without the daily mileage amount.

I can make one up. Suppose it is 75 cents a mile

75 ≥ 30 + 0.75 * x       Subtract 30 from both sides

75 - 30 ≥ 0.75*x

40 ≥ 0.75*x                 Divide by 0.75

40/0.75 ≥ x

53.33 miles = x  

Anything more and you are going over budget. Anything less is fine.

This is enough to get you started without knowing what the rate per mile is.

Answer:

(a). 6 ; (b). $5 ;  (c). Larry'c ; (d) at time they open their accounts.

Step-by-step explanation:

Larry's saving habits is [tex]y_{L}[/tex] = 15x + 5

Tom's saving habits:

m = (30 - 18) / (2 - 1) = 12 and b = 18 - 12 = 6

[tex]y_{T}[/tex] = 12x + 6

(a). $6

(b). $5

(c). Larry'c ( [tex]m_{L}[/tex] = $15 , [tex]m_{T}[/tex] = $12 )

(d). When [tex]y_{T}[/tex] > [tex]y_{L}[/tex] ?

15x + 5 < 12x + 6

3x < 1

x < [tex]\frac{1}{3}[/tex] of [tex]1^{st}[/tex] week ( x ∈ [0, 1) )⇒ Tom will have more money in his account than Larry at time they open their accounts.

Answer:

8 yards

Step-by-step explanation:

there are 3 feet in one yard so 24 divided by 3 is 8

Answer:

-11

Step-by-step explanation:

Answer:

the answer is c. because the awnser is 47.5 and round upto the nearest whole number si 50

Step-by-step explanation: if the yard stick is  3ft and the shadow is 4ft that means the shadow of the stick is 1ft longer than the stick itself.

so if the shadow of the flag pole is 20ft than you -1 and get 19 as shown "20 - 1 = 19" then it said the rope needs to be 2.5 times as long as the pole so you multply 19 by 2.5 as shown "19 x 2.5 = 47.5" round up its 50ft. so there you go hope it helped let me know

Answer:

w=4

Step-by-step explanation:

Answer:

D, 2; 5

Step-by-step explanation:

Sum the equations vertically to eliminate at least one variable.

You will obtain 8y = 40.

Divide both sides by 8. You will get y = 5.

Now we know the value or y. Substitute this value into the second equation (-6x+4y = 8). You will get -6x+(4×5) = 8. Multiply 4 and 5: -6x+20 = 8.

Solve for x by moving 20 to the other side and switching sign: -6x = 8-20.

So: -6x = -12 and therefore x = 2.

So now we know the value of x and y.

(x; y) = (2; 5)

Answer:

88.2

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relevant relation ...

 Tan = Opposite/Adjacent

 tan(10°) = x/500

 x = 500·tan(10°)

 x  ≈ 88.2 . . . . units

Step-by-step explanation:

Answer:

The piecewise function is given as follows;

[tex]\begin{cases}C(n) = \$ 3.45 \times n & \text{ if } x< 4 \\ C(n) = \$ 3.00 \times n & \text{ if } x\geq 4 \end{cases}[/tex]

Step-by-step explanation:

The given parameters are;

The cost of each bag of snickers = $3.45

The cost of each bag of sneakers when buying 4 or more bags = $3.00

Let "n" be the number of bags of snickers and "C(n)" be the cost of all the snickers purchased

The piecewise function is C(n) = {($3.45 × n) for n < 3

{($3.00 × n) for n ≥ 4

Answer:

There are various answers... x-6 or 10x-6-9x or (5x-3)2-9x or (-3+5x)2-9x

Step-by-step explanation:

We all just have to distributive or simplify

Answer:

C. 2x² + 6x - 1 = 0

Step-by-step explanation:

2x² - 3 = -6x - 2

2x² - 3 + 6x = -6x + 6x - 2

2x² - 3 + 6x = -2

2x² - 3 + 6x + 2 = -2 + 2

2x² + 6x - 1 = 0

Hope that helps.

Answer:

-4/3

have a nice day/night

Answer:

x = -25/3

Step-by-step explanation:

x divided by -5/2 is equal to x multiplied by -2/5

therefore, proportion is [tex]\frac{10}{3}[/tex] = [tex]\frac{-2x}{5}[/tex]

cross-multiply: -6x = 50

x = -50/6 or -25/3

Answer:

108 deg

Step-by-step explanation:

Since sides DB and CD are congruent, then opposite angles are congruent.

m<C = m<B = 36

m<B + m<C + m<D = 180

36 + 36 + m<D = 180

m<D = 108

Answer:

x = - 1, y = 2, z = 1

Step-by-step explanation:

Given the 3 equations

2x - y + 3z = - 1 → (1)

x + 2y - 4z = - 1 → (2)

y - 2z = 0 → (3)

Add (1) and (3) term by term

2x + z = - 1 → (4)

Multiply (1) by 2

4x - 2y + 6z = - 2 → (5)

Add (2) and (5) term by term

5x + 2z = - 3 → (6)

Multiply (4) by - 2

- 4x - 2z = 2 → (7)

Add (6) and (7) term by term

x = - 1

Substitute x = - 1 into (4)

- 2 + z = - 1 ( add 2 to both sides )

z = 1

Substitute x = - 1, z = 1 into (2)

- 1 + 2y - 4 = - 1

- 5 + 2y = - 1 ( add 5 to both sides )

2y = 4 ( divide both sides by 2 )

y = 2

solution is (x, y, z ) = (- 1, 2, 1 )

Answer:

My buddy what's popping??

Step-by-step explanation:

Those coming from the Pest end had to walk round the Castle Hill on the Buda side to be able to proceed northwards. On 10 February 1853, four years after the completion of the Chain Bridge, the building of a tunnel leading through the hill was started to the plans of Adam Clark. On 6 March 1856, the tunnel was opened for foot traffic, and on 30 April 1857 also for motor traffic. Being 350 meters in length, it leads through under the Buda Castle to the other side of the hill. Its length is approximately identical to that of the Chain Bridge, prompting anecdotes according to which the tunnel has only been built so that in rainy weather, the Chain Bridge can be shoved in and be protected from wet conditions. The entry of the tunnel at its Chain Bridge end was also fittingly designed in classicist style.

Answer:

At right is the tunnel entrance that runs through Castle Hill in Budapest, Hungary.-a If the maximum height of the tunnel is the same as its maximum width, 9.8 meters, determine a quadratic model to represent the tunnel-b State a geometric model that could be used to represent a truck passing through the tunnel.

The height of the plane to the nearest mile is 175 miles

Step-by-step explanation:

Here, we want to calculate the direction of the plane

A diagrammatic representation of this will be interesting

Please check an attachment for this

From the diagram, consider the triangle OAB

we want to calculate the height of this triangle

We simply apply trigonometric identity

Thus, we have that;

Sine 33 = h/322

h = 322 sine 33

h = 175.37

h is approximately 175 miles

Answer:

:$5.50

Step-by-step explanation:

You will give your co-worker $5.5.

Given is that you work in a restaurant, and a family comes in for dinner. You and your co-worker wait on the table and prepare their food. The family gives you a $11 tip.

For evenly splitting the tip, you will give your co - worker :

{x} = 11/2 = 5.5

{x} = $5.5

Therefore, you will give your co-worker $5.5.
