Answer:

v = 30 km/h

Step-by-step explanation:

Given that,

Distance covered by a car, d = 120 miles

Time, t = 4 hours

We need to find the speed of the car. The speed of an object is equal to the distance covered divided by the time taken. It can be given by :

[tex]v=\dfrac{d}{t}\\\\v=\dfrac{120\ \text{miles}}{4\ \text{hour}}\\\\v=30\ \text{mph}[/tex]

So, the speed of the car is 30 km/h.

-2 < 12

Step-by-step explanation:

12 is bigger than -2.

Answer:

the answer is C because it's the only one that doesn't have any repeating x-values or repeating y-values.

D is incorrect because it's saying that no matter what the x-value is, the y-value will come out to be 6. that isn't a function

a function is when every x-value produces it's own y-value when plugged into the equation

Answer:

2(12x-1)

Step-by-step explanation:

expand the expression

24x-12+10

add the constants

24x-2

take out 2, since it is common

2(12x-1)

Answer:

The equation is;

C = kg

c is the cost in $

k is the proportionality constant $/can

g is the number of cans

cost of 5 cans of coffee is $46.25

Step-by-step explanation:

From the question, 2 cans of ground coffee costs $18.50

Let c be the cost and g be the number of ground coffee

18.50 = k * 2

where k is the constant of proportionality;

k = 18.5/2

k = 9.25

So, the cost of 5 coffee cans will be;

c = 9.25 * 5 = $46.25

Answer:

∠A =  115°

∠B =  65°

∠C =  115°

∠D =  65°

Step-by-step explanation:

The figure given is of parallelogram.

We need to find measure of each interior angle.

We are given:

∠A = (2x-15)°

∠B = x°

∠C = (2x-15)°

∠D = x°

We need to find measure of ∠A , ∠B, ∠C, ∠D

We know that sum of all angles of parallelogram = 360°

So, we can write: ∠A +∠B+ ∠C+ ∠D = 360°

Now putting their values and finding value of x first:

[tex]2x-15+x+2x-15+x=360\\Combining\:like\:terms:\\2x+x+2x+x-15-15=360\\6x-30=360\\6x=360+30\\6x=390\\x=\frac{390}{6}\\x=65[/tex]

So, we get x= 65

Now finding measure of each angle:

∠A = (2x-15)° = 2(65)-15 = 130-15 = 115°

∠B = x° = 65°

∠C = (2x-15)° = 2(65)-15 = 130-15 = 115°

∠D = x°= 65°

Answer is:

∠A =  115°

∠B =  65°

∠C =  115°

∠D =  65°

Answer:

Slope = - 4

Step-by-step explanation:

-3y = 12x + 6

Divide the equation by (-3)

[tex]\frac{-3y}{-3}=\frac{12}{-3}x+\frac{6}{-3}\\\\[/tex]

y = -4x - 2

Compare with y = mx + b

m = -4

Answer:

I believe it is Y=30+2x

Step-by-step explanation:

Since the $30 is given no matter what, we can use it as b.

Since slope always changes, we use it as our m.

X= amount of people

2= charge per person

If there were 5 people there, the equation would look like this: y= $2(5)+$30

The dollar signs are just an aid.

Answer:

Y=2x+30

Step-by-step explanation:

The b is 30

While the slope is 2

Using y=mx+b that will be your answer.

Answer:

$11.23

Step-by-step explanation:

To find the unit price divide the price by the product. For example, 12 ounces of juice costs $2.45. You divide $2.45 by 12 ounces. The unit price would be $0.20.

A 7-pack of tickets to the zoo costs $78.61. Therefore, the unit price of ticket to the zoo $11.23.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into same number of parts.

Given that a 7-pack of tickets to the zoo costs $78.61.

To find the unit price;

Cost of one pack of ticket to the zoo = total cost of 7 pack of tickets / number of tickets

Cost of one pack of ticket to the zoo = $78.61 / 7

Cost of one pack of ticket to the zoo = $11.23

Therefore, the unit price of ticket to the zoo $11.23.
