Answer:

Number of different cones made = 18

Step-by-step explanation:

Given:

Types of cone = 2

Number of flavors = 3

Number of toppings = 2

Find:

Number of different cones made

Computation:

Number of different toppings = 1(peanuts) + 1(sprinkles) + 1(both) = 3

Number of different cones made = Types of cone × Number of flavors × Number of different toppings

Number of different cones made = 2 × 3 × 3

Number of different cones made = 18

Answer:

30, 85, 95, 150

Step-by-step explanation:

The angles of a quadrilateral add to 360

Let x be the smallest angle

x+55

x+65

x+120 are the other three angles

Add the 4 angles together and they sum to 360

x+x+55 x+65+ x+120 = 360

Combine like terms

4x+240 = 360

Subtract 240 from each side

4x+240-240 = 360 -240

4x = 120

Divide by 4

4x/4 = 120/4

x = 30

x+55= 30+55 = 85

x+65 = 30+65 = 95

x+120 = 30+120 = 150

Answer:

y = - 4x - 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 4 , thus

y = - 4x + c ← is the partial equation

To find c substitute (- 4, 6) into the partial equation

6 = 16 + c ⇒ c = 6 - 16 = - 10

y = - 4x - 10 ← equation of line

Answer:

y = -4x+10

Step-by-step explanation:

Using the slope intercept form of a line

y = mx+b where m is the slope and b is the y intercept

y = -4x +b

Substituting the point in

6 = -4(-4) + b

6 = 16+b

Subtract 16 from each side

-10 =b

The equation is

y = -4x+10

Barry has to pay back $1150

Step-by-step explanation:

We can set up an equation to help solve this problem

x is the amount he has to pay back

x=1000+3(1000/20)

1000/20 lets us know how many times he borrowed 20 dollars

x=1000+3(50)

x=1000+150

x=1150

Barry has to pay back $1150

If Barry also looks into the cost of repaying an easy access loan for $1000. The up-front cost of the loan is $3 for every $20 borrowed, plus the original $1000. Then Barry has to pay back $1150.

Two or more expressions with an equal sign is called as Equation.

We can set up an equation to help solve this problem

Answer:

c. -1; no

Step-by-step explanation:

The inner product of 2 vector (a,b) and (c,d) is:

(a,b)(c,d) = a*c + b*d

If the inner product is equal to 0,  the vectors are perpendicular.

So, the inner product of (5,2) and (-3,7) is equal to:

 (5, 2)×(-3, 7) = 5(-3) + 2(7) = -1

The inner product is -1, it is different to 0, so the vectors are not perpendicular.

A: 5 + 8 = 13

B: 6 + 7 = 13

C: 7 + 2 = 9

However, D is greater than 13 and is the correct answer.

D: 8 + 8 = 16.

Option d: 8 cm and 9 cm.

There is a theorem in mathematics stating:

" The sum of length of two sides of any triangle is greater than the rest third side"

According to that theorem, first three given options cant form the sides of the given triangle whose one side is 13 cm.

The 4th option has 8 cm and 9 cm for which we have:

8 + 9 > 13

Answer:

a. 43,200 drips

b. 4 gallons (approximately, actual value is 3.8)

c. 61 cups(approximately, actual value is 60.8, using 3.8 gallons and not 4 gallons)

Step-by-step explanation:

Here, we have a faucet wasting water at a rate of 15 drips per 30 seconds, now we want to calculate the number of drips wasted in a day

To find this, what we need to do is fund the number of seconds in a day first

There are 24 hours with 60 minutes, with each minute having 60 seconds

So the number of seconds in a day = 24 * 60 * 60 = 86,400 seconds

Now 15 drips is wasted in 30 seconds

x will be wasted in 86,400 seconds

x = (15 * 86400)/30 = 43,200 drips are wasted in a day

b. Mathematically , there are about 3,000 drips in a liter of water

So;

3,000 drips = 1 liter

43,200 drips = x liter

x = 43200/3000 = 14.4 liters of water

Mathematically,

1 liter = 0.264 gallons

So 14.4 liters = 14.4 * 0.264 = 3.8 gallon

which is equal to 4 gallons of water approximately

c. Mathematically;

1 gallon = 16 cups of water

So 3.8 gallons of water will measure 3.8 * 16 = 60.8 which is approximately 61 gallons of water

Explanation:

Writing [tex]P \to Q[/tex] is another way of saying "if P, then Q".

P and Q are placeholders. Instead of holding numbers, they hold statements. The statements can be anything you want (generally they should be something that can be verified).

The two statements are

P: x = 5

Q: 2x = 10

So the format "if P, then Q" turns into "if x = 5, then 2x = 10" after replacing P and Q with the proper definitions.

Answer:

Step-by-step explanation:

If a shoemaker makes three new souls every four minutes, the number of soles he will make in an hour can expressed as shown;

3 souls = 4 minutes

x souls = 1hour (60 minutes)

Cross multiplying to get the number of souls;

4 * x = 3 * 60

4x = 180

x = 180/4

x = 45souls

Hence the number of souls made by this shoemaker in an hour is 45 souls.

Similarly, If another shoemaker makes two new souls every three minutes, the number of soles he will make in an hour can expressed as shown;

2 souls = 3 minutes

y souls = 1hour (60 minutes)

Cross multiplying to get the number of souls;

3 * y = 2 * 60

3y = 120

y = 120/4

y = 30souls

Therefore the number of souls made by this shoemaker in an hour is 30 souls.

The difference in the number souls they made in an hour will be x - y where x = 45 souls and y = 30 souls.

x - y = 45 - 30

The difference is equal to 15 souls

[tex]Values: \{0,1,2,3,4,5,6,7,8,9,10\}[/tex]

Required

Select all values that belongs to the domain of the given function

Analyzing the question;

The question says that the function, m represent the amount left after buying b number of books

This means that, after purchasing b books, I'm expected to have a certain m amount of dollars left with me;

This implies that the value of m can never be negative;

So, the domain of m are values of b such that [tex]m \geq 0[/tex]

When b = 0

[tex]m = 45 - 7.5(0)[/tex]

[tex]m = 45 - 0[/tex]

[tex]m = 45[/tex]

When b = 1

[tex]m = 45 - 7.5(1)[/tex]

[tex]m = 45 - 7.5[/tex]

[tex]m = 37.5[/tex]

When b = 2

[tex]m = 45 - 7.5(2)[/tex]

[tex]m = 45 - 15[/tex]

[tex]m = 30[/tex]

When b = 3

[tex]m = 45 - 7.5(3)[/tex]

[tex]m = 45 - 22.5[/tex]

[tex]m = 22.5[/tex]

When b = 4

[tex]m = 45 - 7.5(4)[/tex]

[tex]m = 45 - 30[/tex]

[tex]m = 15[/tex]

When b = 5

[tex]m = 45 - 7.5(5)[/tex]

[tex]m = 45 - 37.5[/tex]

[tex]m = 7.5[/tex]

When b = 6

[tex]m = 45 - 7.5(6)[/tex]

[tex]m = 45 - 45[/tex]

[tex]m = 0[/tex]

When b = 7

[tex]m = 45 - 7.5(7)[/tex]

[tex]m = 45 - 52.5[/tex]

[tex]m = -7.5[/tex]

There's no need to check for other values, as they will result in negative values of m;

Hence, the domain of m are:

[tex]Domain: \{0,1,2,3,4,5,6\}[/tex]

The values that are in the domain of the function are 7, 8, 9 and 10

Given the linear function  m=45−7.5b

where:

For th domain to exist, then;

45 - 7.5b< 0

7.5 b > 45

b > 45/7.5

b > 6

Hence the values that are in the domain of the function are 7, 8, 9 and 10
