Step-by-step explanation:

Liam had a stack of 50c coins. He spent €2.75 and had €1.75 left. How much did he have at the start?

Answers

Answer:

Total coins Liam at the start = 9

Total money Liam in the start = €4.5

Total money Liam in the start = 450 cent

Step-by-step explanation:

We know that

1€ = 100 cent

⇒1 cent = 0.01 €

⇒50 cent = 0.5€

Now,

Total money spent = €2.75

Total money left = € 1.75

So, Total money in the initial = Total money spent + Total money left

                                               = €2.75 + €1.75 = €4.5

⇒Total money in the initial = €4.5

Now,

1€ = 100 cent

⇒€4.5 = 450 cent

Now,

As Liam has a stock of 50 cent coins

So, total coins Liam left with = 450/50 = 9 coins

B. Horizontal 7.2 and vertical 18.9
C. Horizontal 18.9 and vertical 7.2
D. Horizontal 15.2 and vertical 9.6

Answers

B is your answer

I guess

The initial vertical and horizontal velocity of the ball will be 18.9 feet per second and 7.2 feet per second, respectively. Then the correct option is C.

What is a vector?

The quantity which has magnitude, and direction and follows the law of vector addition is called a vector.

George Washington tosses a baseball with an underlying speed of 20.2 feet each second at a point of 69° degrees with the even.

The initial vertical velocity of the ball is given as,

⇒ 20.2 x sin 69°

⇒ 20.2 x 0.9335

⇒ 18.9 feet per second

The initial horizontal velocity of the ball is given as,

⇒ 20.2 x cos 69°

⇒ 20.2 x 0.3583

⇒ 7.2 feet per second

The initial vertical and horizontal velocity of the ball will be 18.9 feet per second and 7.2 feet per second, respectively. Then the correct option is C.

Answer:

Step-by-step explanation:

each wand = 2 so you add the wands and multiply the wands by 2

then you divide the answer to the last calculation by 4

which is 28 divided by 4

which = 7

The mean of the data is 7.

What is Arithmetic Mean?

The simplest and most popular way to measure a mean or average is the arithmetic mean. It simply entails adding up a collection of numbers, then dividing that total by the total number of numbers in the series.

Given:

Glenda = 2 x 2= 4 wands

Tink = 3 x 2= 6 wands

Merry = 4 x 2= 8 wands

Gracie = 5 x 2= 10 wands'

So, Arithmetic Mean = (Sum of wands) / (Total number of wands)

                                  = (4+ 6 +8 + 10)/4

                                  = 28/4

                                  = 7

Hence, the mean is 7.

The Hernandez family orders 3 large pizzas. They cut the pizzas so that each pizza has the same number of slices, giving them a total of 24 slices.
The Wilson family also orders several large pizzas from the same pizza restaurant. They also cut the pizzas so that all their pizzas have the same number of slices. For the Wilson family, the equation y = 10x represents the relationship, where x represents the number of pizzas and y represents the number of total slices.
Which statements best describe the pizzas bought by the Hernandez and Wilson families? Select two options.
For the Hernandez family, the equation y = 3x represents the relationship between the number of slices and number of pizzas, where x represents the number of pizzas and y represents the number of total slices.
For each family, a graph of the relationship between number of pizzas, x, and number of slices, y, goes through the point (0, 0) and is a straight line.
The Hernandez family’s slices are smaller than the Wilson family’s slices.
If the Wilson family ordered 3 large pizzas from the same restaurant as the Hernandez family, they would have more slices than the Hernandez family after each family cut their pizzas into slices.
The constant of proportionality is 10 for the Wilson family, but cannot be determined for the Hernandez family.

Write an equation of the line in slope-intercept form. (0,2) (3,3) ​

Answers

i dont see an image

Step-by-step explanation:

Answer: y = 1/3x +2

Step-by-step explanation:

The slope-intercept form of an equation looks like this:

y=mx+b

The m stands for the slope and the b stands for the y-intercept. We need two points on the line to write out this equation.

We have the two points you entered, so let's start by getting the slope. (1/3)

Now that we have the slope, we can plug it into our equation: y = 1/3x+b

To get b, our y-intercept, we just need to plug in one of the points you entered and solve. Now that we have both our m and b values, we can plug them in to get our equation: Y= 1/3x+2

Answer:

i. Mean = 11.2

ii. Variance = 14.17

iii. Standard deviation = 3.76

Step-by-step explanation:

i. Mean, m = [tex]\frac{sum of the values}{number of the values}[/tex]

                = [tex]\frac{4+11+12+12+13+15}{6}[/tex]

                = 11.2

The mean of the given data is 11.2

ii. Variance = [tex]\frac{sum(x_{i} - m)^{2}}{n-1}[/tex]

where:   [tex]x_{i}[/tex] is the value of the one observation, m is the sample mean and n is the number of data given.

                   = [tex]\frac{[(4-11.2)^{2}+(11-11.2)^{2} + (12-11.2)^{2} + (12-11.2)^{2} + (13-11.2)^{2} + (15-11.2)^{2}] }{6-1}[/tex]

                   = [tex]\frac{70.84}{5}[/tex]

                   = 14.168

Variance = 14.17

iii. Standard deviation = [tex]\sqrt{Variance}[/tex]

Answers

Answer:

Step-by-step explanation:

First find the rate of change or slope denoted as m

m=(y2-y1)(x2-x1) we can find the slope with any two points.

m=(35000-25000)/(600-200)

m=10000/400

m=25

Now that we know the slope we can find the y intercept or original cost

C(n)=25n+b, using any point we can solve for b, I’ll use (200, 25000)

25000=25(200)+b

25000=5000+b

b=20000 so now we know the complete equation.

C(n)=25n+20000

A taxi driver charges you $1.50 for the first mile and $.90 for each additional mile. How far could you go for $20.00 if you give the driver a $2.00 tip?

Answers

Answer:

You can go 19.33 miles for $20.00 if you give the driver a $2.00 tip.

Step-by-step explanation:

From the information provided, you can say that the total cost of the taxi is equal to the cost of the first mile plus the price for each additional mile for the number of additional miles, which can be expressed as:

c=1.50+0.90(x-1), where

c is the total cost

x is the number of miles

Now, if you want to determine how far you can go for $20 if you give the driver a $2.00 tip, first you have to subtract the tip from the amount you have:

20-2=18

Then, you know that you have $18 for the cost of the taxi and you can replace c with this value and solve for x to find the number of miles:

18=1.50+0.90(x-1)

18-1.50=0.90x-0.90

16.5+0.90=0.90x

17.4=0.90x

x=17.4/0.9

x=19.33

According to this, the answer is that you can go 19.33 miles for $20.00 if you give the driver a $2.00 tip.

You can go 19.33 mile
