30. Tickets to a concert are $24 apiece. There is also a $5 handling fee for the
entire order. You and some friends ordered tickets and the bill came to a total
of $173. How many tickets did you order?

Answer:

-10=$35r+$5r

+10=$30r

Step-by-step explanation:

This function represents this situation. If someone orders less than ten rings (-10) then they will pay $35 for each ring($35r) plus dollars for each for shipping ($5r)

If someone were to buy more than ten rings (+10) then they will pay $30 for each ring ($30r)

Have a great day!

Answer:

dx/dt | (x=3) = 27/2

Explanation:

x*y = 2 ......... (a)

At x = 3, (3)*y = 2 => y = 2/3

Differentiate (a) wrt t,

x.dy/dt + y.dx/dt = 0 ........ (b)

Put x=3, dy/dt=-3 and y=2/3 in the differential equation (b),

3(-3) + (2/3)*dx/dt = 0

dx/dt = (9*3)/2 = 27/2

Answer:

$ 3.75

Step-by-step explanation:

Let the unknown price be x.

Ounces                                 cost

16                ⇒                  $ 2.50

24                ⇒                   x

Now let us use cross multiplication and find the value of x.

16 × x = 24 × 2.50

16x = 60

Divide both sides by 16.

x = 3.75

Therefore, 24 ounces of bulk rice cost $ 3.75

Hope this helps you :-)

Answer:

Exact Form= 6√10

Decimal Form=18.97366596

Answer:

Yes, they are equivalent expressions, by the Associative Property

Step-by-step explanation:

Both of these expressions are equal to:

4a + 5a + 3c

(and then, 9a + 3c)

This is all adding so you can add them all up without any of the parentheses. In the question at first the parentheses are grouping together the 5a and 3c, but in the second expression they are wrapped around the 4a and 5a. But in both expressions the order of the three terms does not change. Only the grouping changes. The terms are grouped differently, but the order DOES NOT change. This is Associative property. If the order changes it is Commutative property.

Answer:Find all times on the clock where the angle between the minute and the hour hand (backwards and forwards) equals 26°

Using our clock angle calculator for 5:32, we see that the angle between the hands equals 26°

Using our clock angle calculator for 6:28, we see that the angle between the hands equals 26°

Final Times that form an angle of 26°

Step-by-step explanation:

Step-by-step explanation:

1. cd and dg

2. angle 2

3. angle gde

4. angle cdh

5. cde is st line

6.cdf = cdh+hdf = 42+117= 159

7. angle fde = 90-73=17

Answer:

2 acute angles

Step-by-step explanation:

A right triangle HAS to have a right angle, which is 90 degrees. This means the other two angles must add up to:

180-90 = 90 degrees

Acute angles are LESS than 90 degrees. You cannot add two positive integers over 90 to get 90 (obtuse angles), and you can also not have two 90 degree angles since that forms a straight line, therefore meaning the other two angles must be acute.

Answer:

2

Step-by-step explanation:a normal right triangle has 3 angles in total and looking at the bend in each corner only two of them are acute so that makes it 2

See screenshot below! :^)

Hope this helps! :^)

Special right triangles are triangles whose sides are in a particular ratio, known as Pythagorean Triples. In geometry, the Pythagorean Theorem is a statement that shows the relationship of the sides of a right triangle. ... The two special right triangles include: 45°; 45°; 90° Triangle

Answer:

Tree A equation: y = 2x + 5. Tree B equation: y = 3x + 8.

Step-by-step explanation:

The rate at which the tree's grow each month is m (y=mx + b) and the starting length of the trees is b (y=mx+b). Once you know those values plug them into the equation.

Answer:

13.71% or rounded we have 14%

Step-by-step explanation:

We need to find the area so we need to use the formula of Area = piR^2

>> Area of bulls-eye = π(2.5)^2 = 19.63in^2

>> Area of whole target = π(6.75)^2 = 143.13in^2

NOTE: The target values above are halved values of 5 and 13.5

Now, all we have to do is divide the area of the bullseye by the area of the target, so some simple stuff.

19.63/143.13 > 0.13714804 > In a percent we have 13.71% or rounded we have 14%

Answer: Irrigation water can come from groundwater, through springs or wells, surface water, through rivers, lakes, or reservoirs, or even other sources, such as treated wastewater or desalinated water. As a result, it is critical that farmers protect their agricultural water source to minimize the potential for contamination.

Answer:

Total pipes = 692 pipes

Step-by-step explanation:

Now we have to,

→ find the amount of pipes he use.

Forming the expression,

→ 610 plastic pipes + 82 metal pipes

Let's solve the problem,

→ 610 plastic pipes + 82 metal pipes

→ 610 + 82

→ 692 pipes

Hence, the farmer used 692 pipes.
