Answer:

€107.69

Step-by-step explanation:

If $2=€1.78 then $1= €0.89

0.89*121= €107.69

The 107.69 Euros will Roscoe have for trip to Germany.

It is required to find how many Euros will Roscoe have for trip to Germany.

The arithmetic refers to working with numbers by doing addition, subtraction, multiplication, and division. Fractions, decimals, percentages, fractions, square root, exponents, and other arithmetic operations are used to achieve mathematical simplifications.

Given:

Roscoe is exchanging $ 121 for Euros.

If $2 can be exchanged for 1.78 Euros.

$2=€1.78

then $1= €0.89

For  $ 121=

=0.89*121

= €107.69

Therefore, the 107.69 Euros will Roscoe have for trip to Germany.

Answer:

The area is 155 ft.

Step-by-step explanation:

To find the area if a trapezoid, you have to add the number on top( in this case 13 ft) and then add that with the bottom number(18 ft.) Then, you take that answer and divide it by 2. After that, multiply it with the height(10.) Thus, the answer is 155 ft.

Answer:

A linear formula for S as a function of D is S=17D+1534

Step-by-step explanation:

We are supposed to find a linear formula for S as a function of D.

Equation of line : y = mx+c

We are given that At the surface, the speed of sound is 1534 meters per second.

c = 1534

We are given that for each increase in depth by 1 km, the speed increases by 17 m/s

So, Slope = m = 17

Substitute the values in equation

y=17x+1534

x denotes depth

y denotes speed

We are given that Use D for depth and S for the speed of sound

So, S=17D+1534

Hence a linear formula for S as a function of D is S=17D+1534

Answer:

C. [tex] y = 3.50 + 2.75x [/tex]

Step-by-step explanation:

Initial fee charged by the taxi driver = $3.50

Fee charged per kilometer = $2.75

Number of kilometers of travel = x

Total cost charged for a trip = y = initial fee charged for renting a taxi + fee paid based on the number of kilometers travelled

Total cost of the trip can be expressed by the following equation:

[tex] y = 3.50 + 2.75x [/tex]

The answer is C. [tex] y = 3.50 + 2.75x [/tex].

Answer:

Step-by-step explanation:

The probability that the winning three numbers match the date on any given​ day is the likelihood of the winning number

Start by calculating the number of possible outcomes

Each of the three digits can take any of 0 - 9 i.e. 10 digits.

So, the number of possible outcomes is:

[tex]n =10^3[/tex]

[tex]n =1000[/tex]

There can be only one winning date.

So, the probability (p) is:

[tex]p = \frac 1n[/tex]

This gives

[tex]p = \frac 1{1000}[/tex]

[tex]p = 0.001[/tex]

Hence, the probability that the winning three numbers match the date on any given​ day is 0.001

In a calendar year, there are 65 days, where the whole year passes without matching the winning numbers.

The dates are:

This means that the matching numbers can occur on the remaining 300 days.

The probability that the winning date does not occur on a date is calculated using the following complement rule

[tex]p' = 1 - p[/tex]

So, we have:

[tex]p' = 1 - 0.001[/tex]

[tex]p' = 0.999[/tex]

For the 300 days, we have:

[tex]p = 0.999^{300}[/tex]

[tex]p = 0.7407[/tex]

Hence, the probability that a whole year passes without this​ happening is 0.7407

This is calculated using the following complement rule

[tex]p' = 1 - p[/tex]

So, we have:

[tex]p' = 1 - 0.7407[/tex]

[tex]p' = 0.2593[/tex]

Hence, the probability that the date and winning lottery number match at least once during any​ year is 0.2593

In (b), we have:

[tex]p' = 0.999[/tex]

So, the probability is calculated as:

[tex]p =1 - (p')^n[/tex]

Where n is the number of states i.e. n = 27.

So, we have:

[tex]p = 1 - 0.999^{27}[/tex]

[tex]p = 0.0267[/tex]

Hence, the probability that at least one of them will come up 1-1-4 on January 14​ is 0.0267

0.02 tons per cubic foot

Step-by-step explanation:

delt math

The density of the material is, 106.36 tons per cubic foot.

Density is the mass of a material substance per unit volume.

d = M/V, where d is density, M is mass, and V is volume, is the formula for density.

Grams per cubic centimeter are a typical unit of measurement for density.

Given, The density of a certain material is such that it weighs 1 pound for every 3.5 cups.

Therefore, d = 1/3.5 per cubic cup.

d = 0.29 pounds per cubic cup.

Now, We know 1 ton is equal to 2000 pounds and 1 foot is equal to 119688.

Therefore, The density of the material per cubic foot is,

= 119688/(2000×0.29) tons per cubic foot.

= 106.36 tons per cubic foot.

Answer:

x = 2.6, x = -1.6

Step-by-step explanation:

If we compare the graph to points (-1, 2) and (2, 2) [see blue lines on attachment], we can determine that the scale of the y-axis is 1 square per 1 unit.  (This is different from the scale of x-axis, which is 2 squares per unit).

Therefore, to use the graph to estimate the x-value when y = 4, count 4 square up the y-axis from 0, then trace along the horizontal line until you meet the curve.  Then trace down to the x-axis and read the values of x. (shown by the red lines on the attachment).

So the approximate value of x is -1.6 and 2.6 when y = 4.

The actual answer can be calculated as follows:

   x² - x = 4

⇒ x² - x - 4 = 0

Use the quadratic formula:

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

[tex]\implies x=\dfrac{-(-1)\pm\sqrt{(-1)^2-4(1)(-4)}}{2(1)}[/tex]

[tex]\implies x=\dfrac{1\pm\sqrt{17}}{2}[/tex]

Colin's mean score of his 10 runs is 18.8.

Colin's new mean score after the game on Sunday is 20.

Mean is a measure of central tendency. It is used to describe a data set. It is the sum of a set of observations divided by the number of observations. It is also known as average.

Mean = sum of scores / total number of scores.

Colin's mean scores can be determined by dividing the sum of scores by total number of scores.

Sum of scores = (20 + 29 + 34 + 19 + 8 + 12 + 0 + 23 + 29 + 14) = 188

Number of scores = 10

Mean of scores = 188 / 10 = 18.8

Colin's new mean score can be determined by adding 32 to the sum of scores already determined and dividing the sum by the total number of scores.

New sum of scores = 188 + 32 = 220

Number of scores = 11

Mean scores = 220 / 11 = 20
