what is the sum of x and 16 is less than 32?

Answers

Answer:

I don't know the exact question you're asking, but the solution for x would be x16.

Members of a lacrosse team raised $1775-50 to go to a tournament. They rented a bus
for $901.50 and budgeted $46 per player for meals. Write and solve an equation
which can be used to determine x, the number of players the team can bring to the
tournament.

Answers

Considering the definition of an equation and the way to solve it, the equation is 901.5 + 46x= 1775.50  and the number of players the team can bring to the tournament is 19.

Definition of equation

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear.

The members of an equation are each of the expressions that appear on both sides of the equal sign while the terms of an equation are the addends that form the members of an equation.

The solution of a equation means determining the value that satisfies it and the equality must be true. To solve an equation, keep in mind:

When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.

This case

Being "x" the number of players the team can bring to the tournament, and knowing that:

Members of a lacrosse team raised $1775.50 to go to a tournament. They rented a bus for $901.50 and budgeted $46 per player for meals.

the equation in this case is:

901.5 + 46x= 1775.50

Solving:

46x= 1775.50 - 901.5

46x= 874

x= 874 ÷ 46

x=19

Finally, the equation is 901.5 + 46x= 1775.50  and the number of players the team can bring to the tournament is 19.

Answers

a)

Solution,

According to fuel gauge,the petrol left is exactly between 1/2 and 3/4 part of the 40 litres.

i.e. Left fuel = (1/2 + 3/4)/2 litres

Here,

1/2 of 40l = 1/2×40l

= 20l

3/4 of 40l = 3/4×40l

= 30l

Then,

Left fuel = (20l + 30l)/2

= 50l/2

= 25l

Consumed fuel = 40l - 25l

= 15l

Therefore,15 litres of petrol is used to travel 240km

b)

Solution,

Consumed fuel = 15l

Distance covered = 240km

Then,

Fuel consumption rate = 240km/15 l

= 16km/l

Therefore,the rate of petrol consumption is 16km/l of his car for this journey

Step-by-step explanation:

First, align the same terms next to each other so that combining like terms will be easier.

Remember like terms have the same variables and powers. To combine like terms, all you have to do is add/subtract the coefficients (the numbers in from of the variables).

[tex]2xy^{2} +2xy^{2} -3xy^{2} +3x-x-4y^{2}[/tex]

[tex]2xy^{2} +2xy^{2} -3xy^{2} =xy^{2}[/tex]

And [tex]-4y^{2}[/tex] stays the same because there is no term that has [tex]y^{2}[/tex].

So, we have [tex]xy^{2} +2x-4y^{2}[/tex].

Now to evaluate for x= -2 and y= -3 you have to plug them into the simplified expression.

A runner’s times (in minutes) in three races are 6.9, 6.6, and 6.5. The runner will run two more races and wants the average time of all five races to be less than 6.8 minutes. Describe the average time needed in the two races to achieve this goal. The average time in the two races must be less than minutes.

Answers

The average time in two races must be less than 7 minutes.

Given,

Runner's times in three races = 6.9 minutes, 6.6 minutes, 6.5 minutes.

Runner will run two more races.

The average time of all five races = less than 6.8 minutes

We have to find the average time needed in the two races:

Now,

(6.9 + 6.6 + 6.5 + x + y) / 5 < 6.8

Here, x and y are the time in two races.

Let's assume the average as 6.5 which is less than 6.8.

Then,

(6.9 + 6.6 + 6.5 + x + y) / 5 = 6.5

(6.9 + 6.6 + 6.5 + x + y) = (6.5 × 5)

x + y = (6.5 × 5) - (6.9 + 6.6 + 6.5)

x + y = 32.5 - 20

x + y = 12.5

Now, we have to find the average of two races:

That is, (x + y) / 2 = 12.5 / 2 = 6.25.

Above is a solution required by an assumption. By this solution we came to know that the average of two races must be less than 7 minutes.

So, let's conclude like:

The average time in the two races must be less than 7 minutes.

The standard deviation is a measure of variance or dispersion in statistics. Standard deviation, often known as SD, is most frequently represented in mathematical texts and equations by the lowercase Greek letter (sigma), for the population standard deviation, or the Latin letter s, for the sample standard deviation.

Answers

The cone has a volume of (D) 288in3.

What do we mean by volume?A volume is a unit of measure of occupied three-dimensional space. It is frequently quantified numerically using SI-derived units (such as cubic meters and liters) or various imperial modules (such as the gallon, quart, and cubic inch). The definition of volume is related to the definition of length (cubed). The volume of a container is generally recognized to be its capacity; that is, the quantity of fluid (gas or liquid) that it can hold, rather than the amount of space that it occupies.

To find the volume:

Given:

Radius = 6 inheight =?g = 10 inVolume =?

Formula:

Volume of a cone = πr²h / 3

Jess and Marie share money in the ratio of 3:5. If they have 64 dollars, how much does Marie have?
valve

Answers

Answer:  40 dollars

======================================================

Explanation:

The ratio 3:5 is equivalent to 3x:5x after multiplying both parts by x.

Jess has 3x dollars and Marie has 5x dollars

3x+5x = 64

8x = 64

x = 64/8

x = 8

Therefore,

Jess has 3x = 3*8 = 24 dollarsMarie has 5x = 5*8 = 40 dollars

The ratio 24:40 reduces to 3:5 after dividing both parts by the GCF 8.

---------------------------

Another way to solve:

m = amount Marie has

64-m = amount Jess has

3/5 = (64-m)/m

3m = 5(64-m)

3m = 320-5m

3m+5m = 320

8m = 320

m = 320/8

m = 40 dollars is the amount Marie has

From calculating the percentages we can say that 43 more students went on Friday than Saturday.

Percentage is defined as quantity per hundred. Percentage is calculated by dividing the given number by the total number and multiplying it by 100.

From the survey we can see that 550 students were supposed to go on Friday. But it is given that 18 percent students did not go to the festival.

Number of students who went = 550 - (18% of 550 )

Therefore students = 550 - 99 =451 students

Again from the survey we can see that 480 students were supposed to go on Saturday . But it is given that 15 percent students did not go to the festival.

Number of students who went =480 - (15% of 480 )

Therefore students = 480 - 72 = 408 students
