A plane flies 1640 miles in 4 hours . What is the average speed of the plane ??

Answer:

"Jeromar" give away more tickets

Step-by-step explanation:

What we must do is calculate the amount to which a ticket is equivalent, to do this, the value of the purchase must be divided by the number of tickets they give away, as follows:

"Colima"

150/4 = 37.5

In other words, they give away 1 ticket for $ 37.50

"Jeromar"

100/3 = 33.33

In other words, they give away 1 ticket for $ 33.33

Which means that "Jeromar give away more tickets, because the cost of the ticket is lower

Final answer:

The unit rate for meat priced at $32 for 8 pounds is $4 per pound. This method of calculation is important in retail settings, such as butcher shops, where items need to be labeled with the correct price per unit.

Explanation:

The unit rate is calculated by dividing the total price by the number of pounds of meat to determine the price per pound. For $32 and 8lbs of meat, the calculation is $32 ÷ 8lbs, which equals $4 per pound.

This price is a simplified example of how goods are priced on a per unit basis. For instance, if we were discussing the price of fish, the price per pound at an equilibrium quantity may be $3.25 per pound, which is specific to the commercial market.

Real-world Application

Grocery pricing often includes bulk pricing, discounts, or access fees, and the final cost consumers pay can be represented in various unit rates, like $xx.xx/unit in some cases. It’s important for workers in retail settings, such as at a butcher shop or grocery, to understand these concepts to label and price items accordingly.

Answer:

Gradient is -2/3 and y-intercept is -5/3.

Step-by-step explanation:

First, you have to make y the subject by moving all the unrelated terms to the other side :

[tex]3y + 2x + 5 = 0[/tex]

[tex]3y = - 2x - 5[/tex]

[tex]y = - \frac{ 2}{3} x - \frac{5}{3} [/tex]

Next, given that the slope-form equation is, y = mx+b where m is the gradient and b is the y-intercept. (*In a slope-form equation, gradient will always stick with x)

In the equation above, m is -2/3 and b is -5/3.

Subtract the two diameters and multiply by 0.5

Step-by-step explanation:

Calculating the Radius of the hole gives distance to the inner edges WHILE the Radius of the coin gives us the distance to the outer edges.

By subtracting the output we can then get the difference between both distances.

If hole diameter = 5mm and coin diameter = 22mm

Difference = [(22 - 5)mm] ÷ 2

17mm / 2 = 8.5mm

Answer:

It's equal to 0.4999238476

The value of Cos⁻¹(1/2) is π/3 radians or 60 degrees

To solve this:
Cosine function is positive in the first and fourth quadrants.
Cos(60°) = 1/2.
Cos⁻¹(1/2) = 60°.
In radians, this angle is π/3.

Therefore, the value of Cos⁻¹(1/2) is π/3 radians (or 60 degrees).

Answer:

The median number of push-ups is 8.

Step-by-step explanation:

We use the median to find the "middle" value of a sample, that is, the value separating the lower half from the upper half of the sample.

If the size of the sample is even

1,2,3,4

Both the upper half and the lower half should have the same size.

In this case, it is not possible to select only one value which respects this condition. So the mean between 2 and 3 = 2.5 is calculated. This value is not part of the sample.

If the size of the sample is odd

1,2,3,4,5

For a n-sized sample, with n odd, the median is the value at the position (n+1)/2. So her, it is 3, the value at the third position. In this case, it is always going to be an element at a position in the sample, that is, an element of the sample.

In this question:

Initially, we list the number of pushups sorted in an increasing way.

6,8,8,14,18

The size of the sample is 5.

The median value is at the position (5+1)/2 = 3.

So it is 8, which is the element at the 3rd position.

Answer:

18

Answer:

x = -7/3y + 8/3

y = -3/7x + 8/7

Step-by-step explanation:

First, set the equations next to each other to find x and y, I'll start with x:

x + 3y + 2x + 4y = 8

Combine like terms

3x + 7y = 8

Subtract both sides by 7y

3x + 7y - 7y = 8 - 7y

3x = 8 - 7y

I'll re-order the equation to make it easier to divide

3x = -7y + 8

Divide both sides by 3

3x / 3 = -7y + 8 /3

x = -7/3y + 8/3

If you need decimals just divide with a calculator

Now to find y:

We already combined like terms so we don't need to do that again...

3x + 7y = 8

Subtract both sides by 3x

3x - 3x + 7y = 8 - 3x

7y = 8 - 3x

I'll reorder the equation once again so the variable comes first

7y = -3x + 8

Divide both sides by 7

7y / 7 = -3x + 8 / 7

y = -3/7x + 8/7

Again, use a calculator to divide completely for decimals.

Answer:

The percentage of almonds that have been collected is 35%.

Step-by-step explanation:

The question is:

In an orchard, 20% of the kilos of fruit collected are lemons, 15% are pears, 30% are walnuts and the rest are almonds. a) What is the percentage of almonds that have been collected? b) If a total of 140 kilos have been collected, how many kilos have been collected from each fruit or nut?

Solution:

Consider that the percentage of all the fruits and nuts together in a orchard is 100%.

Percentage of lemons = L% = 20%

Percentage of pears = P% = 15%

Percentage of walnuts = W% = 30%

Percentage of almonds= A%

Compute the percentage of almonds that have been collected as follows:

L% + P% + W% + A% = 100%

20% + 15% + 30% + A% = 100%

A% = 100% - 65%

A% = 35%

Thus, the percentage of almonds that have been collected is 35%.

The total weight of products collected is 140 kg.

Compute the weight of lemons collected as follows:

[tex]\text{Weight of lemons}=140\times 20\%=28\ \text{kg}[/tex]

Compute the weight of pears collected as follows:

[tex]\text{Weight of pears}=140\times 15\%=21\ \text{kg}[/tex]

Compute the weight of walnuts collected as follows:

[tex]\text{Weight of walnuts}=140\times 30\%=42\ \text{kg}[/tex]

Compute the weight of almonds collected as follows:

[tex]\text{Weight of almonds}=140\times 35\%=49\ \text{kg}[/tex]

Answer:

290 cm sq.

Step-by-step explanation:

We can approximate this irregular figure as a trapezoid.

We know the area formula for a trapezoid is A = (1/2)*(base1 + base2)*height

A = (1/2)* (22 cm + 36 cm) * (10 cm)

A = (1/2) *( 58 cm)*10 cm

A = 29 cm * 10 cm

A = 290 cm sq.

The answer should be 290 cm2, i will post a comment here later if it is wrong or not. Have a good day :)

Answer:

Yes, he can.

Step-by-step explanation:

Harper has two cans of paint that he would like to combine into one can.

One can contains 6.11 ounces and the other can contains 22.7 ounces.

The total quantity of paint he has is:

6.11 + 22.7 = 28.81 ounces

Since 28.81 ounces is lesser than 29 ounces, he can put both cans of paint into the 29 ounce can of paint.

Answer: 3,017.5 cubic centimeters.

Step-by-step explanation:

Hi, to answer this question we have to calculate the volume of each cd case:

Volume of a rectangular prism= length x width x height

Replacing with the values given:

V = 14.2 x 12.5 x 1 = 177.5 cubic centimeters.

Since there are 17 cases in the stack, we have to multiply the volume one case by 17.

177.5 x 17 = 3,017.5 cubic centimeters.

Answer:

-4   and  -9

Step-by-step explanation:

Let us use variables.

Let x = 5 + y

and  x + y = -13

Now we can solve this problem.

x + y = -13

(5 + y) + y = -13

5 + 2y = -13

2y = -13 - 5

2y = -18

y =  -9

x = 5 + -9

x = -4

The value of two integers are -4 and -9.

A system of equations is a collection of two or more equations with a same set of unknowns. For a system to have a unique solution, the number of equations must equal the number of unknowns.

For the given situation,

Let x and y be the two integers.

The equations are

One integer is 5 more than another integer,

[tex]x = y+5[/tex] --------- (1)

Their sum is -13,

[tex]x+y = -13[/tex] ------- (2)

Now substitute the x value of equation 1 in equation 2,

⇒ [tex](y+5)+y=-13[/tex]

⇒ [tex]2y=-13-5\\[/tex]

⇒ [tex]y=\frac{-18}{2}[/tex]

⇒ [tex]y=-9[/tex]

Now  substitute the y value of equation 1,

⇒ [tex]x=-9+5[/tex]

⇒ [tex]x=-4[/tex]

Hence we can conclude that the value of two integers are -4 and -9.

Answer:

  d.  ZW

Step-by-step explanation:

Corresponding vertices are in the same order in the names of the quadrilaterals. That is P corresponds to Z; Q corresponds to W.

  PQ ≅ ZW

When Quadrilateral PQRS is transformed by rotation and translation to form Quadrilateral ZWXY, the lengths of corresponding segments remain the same. Thus, the length of segment PQ is the same as segment ZW.

In the realm of geometry, a rotation or translation doesn't change the size or length of a shape, only its position and orientation. Therefore, when Quadrilateral PQRS is rotated 90° counterclockwise about the origin and then translated 6 units to the right to form Quadrilateral ZWXY, all corresponding segments would still have the same lengths. Corresponding segments are those that have the same relative positions before and after the transformation. So, in this case, segment ZW has the same length as segment PQ because they are corresponding segments from the original quadrilateral and the transformed quadrilateral, respectively. Therefore, the answer is d. ZW.

Answer:

sqrt(292) = JK

The approximate answer is

17.08800749 = JK

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2

We know the legs JL and LK and are looking for the hypotenuse JK which is opposite and L which is the right angle

6^2 + 16^2 = JK ^2

36 +256 = JK ^2

292 = JK^2

Take the square root of each side

sqrt(292) = sqrt( JK^2)

sqrt(292) = JK

The approximate answer is

17.08800749 = JK

Answer:
