In quadrilateral L M N O, the length of segment M N is two and two-tenths inches and the length of segment N O is four and one-tenth inches. In quadrilateral S T U V, the length of segment T U is unknown and represented by variable x, and the length of segment U V is twelve and three-tenths inches.

Answers

Answer:

6.6 inches

Step-by-step explanation:

4.1 times 3 = 12.3

2.2 times 3 = 6.6

I think this is right... sorry if not

Answer:

x = 6.6

Step-by-step explanation:

In order to solve the missing variable, we need to find the scale factor. I'll just take 12.3 and divide it by its corresponding side that is 4.1.

SF = 12.3/4.1 = 3

Now that we know the scale factor is 3, we can take 2.2 and multiply it by 3 to solve for x.

2.2(3) = 6.6

Therefore, x = 6.6.

Eliana drove her car 81 km and used 9 liters of fuel. She wants to know how many kilometers (x) she can drive on 22 liters of fuel. She assumes her car will continue consuming fuel at the same rate.

Answers

Answer:

I don't know

Step-by-step explanation:

thanks for the pints

Answer:

Step-by-step explanation:

to solve this we need to find the proportional relationship between the miles she can drive per liter of fuel, this can be found easily

we will use this quick formula to find how many miles a liter will give her as shown

81 / 9 = 9

this is the Miles per Liter or MPL, so the car drives 9 miles per liter of fuel, now all we have to do is multiply that new number by the amount of fuel she wonders about like so

9 * 22 = 198

with this, we now know that 22 liters will get her 198 miles down the road, quite the trip id say

this can be used to find the proportional relationship in most problems like this

hope this helped ya out :>

Benji borrows $1500 from a friend who charges him 10% interest. He pays the loan back in 18 months. How much interest did Benji owe his friend? Don't put a dollar sign, just enter the number.

Answers

Answer:

The answer is 2,700

It just said his friend charged him 10% interest. It didn’t mention how much he had to pay back over the 18 months. His friend isn’t a bank. 10% of $1,500 is $150. I would think he owed him $150 in total.
He would be a horrible friend if he charged him $2,700 to borrow just $1,500.

Last Season, A Lacrosse player scored 41 goals in 15 games, So far this season, the player has scored 24 goals in 9 games.

A. Does the player have a greater number of goals per game this season compared with last season?

(I think it is a no. If it is not no, explain)

B. Supposed the player plays in as many games this season as last season and continues to score at this season's rate. Write and solve A proportion to find the number of goals the player will score this season

Answers

Answer:

a. no b. 40.05

Step-by-step explanation:

a. to figure out the number of goals per game you have to divide the total amount of goals by the number of games:

last season: 41 ÷ 15 = 2.73

this season: 24 ÷ 9 = 2.67

as you can see the answer to the last season equation is higher than the this season meaning the player scored more goals last season.

b. we already know that the amount of games the player won each game (all of them supposedly being exactly even) is 2.67. so what we have to do is multiply it by 15 the supposed number of games the player is playing this season to get the total number of goals they will get for the entire season:

2.67 x 15 = 40.05 = the prediction of the total goals of the player

A flat-screen television costs $724.89 when it is new. The value of the television is expected to change by −12 3/5% per year. What is the expected value, to the nearest cent, of the television after 4 years?

Answers

653 no explanation needed it’s just 653

The solution is $ 422.98

The expected value of the television after 4 years is $ 422.98

What is exponential growth factor?

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the initial amount of the television be x₀

The value of x₀ = $ 724.89

Now , value of the television is expected to change by -12 3/5 % per year

So , the exponential decay rate of the television is r = -12 3/5 %

The rate r = -63/5 %

The rate r = -12.6 %

The number of years t = 4 years

So , the exponential decay rate of the television after 4 years is calculated from the formula

x ( t ) = x₀ × ( 1 + r )ⁿ

Substituting the values in the equation , we get

x ( 4 ) = 724.89 ( 1 - ( 12.6/100 ) )⁴

On simplifying the equation , we get

x ( 4 ) = 724.89 ( 1 - 0.126 )⁴

x ( 4 ) = 724.89 ( 0.874 )⁴

x ( 4 ) = 724.89 x 0.583506543376

x ( 4 ) = $ 422.978

So , rounding to the nearest cent , we get

The value of x ( 4 ) = $ 422.98

Hence , The expected value of the television after 4 years is $ 422.98

Jared made 12 3/4 cups of snack mix for a party. His guests ate 2/3 of the mix. How much snack mix did his guests eat?

Answers

Answer:

The guests ate 8 1/2 cups of snack mix.

Step-by-step explanation:

First that find how much is 12 3/4.

12 3/4 = 12,75 cups of snack mix

Let's see how much is 2/3 of 12,75.

To find 2/3 we can divide 12,75 by 3 and multiply the result by 2.

(12,75 : 3) x 2 = 8,5 cups of snack mix.

The area of the trapezium is 175 cm².

Option B is the correct answer.

What is a trapezium?

It is a quadrilateral that has one pair of parallel sides and a height.

The area is calculated as 1/2 x the sum of the parallel sides x height.

Examples:

Area of a trapezium that has the parallel sides as 3 cm and 4 cm and a heght o 5 cm.

Area = 1/2 x (3 + 4) x 5

Area = 1/2 x 7 x 5

Area = 35/2 = 17.5 cm^2

We have,

Parallel sides are b and (c + b).

b = 15 cm

c + b = 5 + 15 = 20 cm

Height = a = 10 cm

Now,

The area of the trapezium.

= 1/2 x (sum of the parallel sides) x height

= 1/2 x (15 + 20) x 10

= 1/2 x 35 x 10

= 35 x 5

= 175 cm²

Thus,

The area of the trapezium is 175 cm².
