Answer:

x = 35 and y = 100

Step-by-step explanation:

Let x = dollar cost per dive  and y = dollar cost per night.

ATQ,

4x+3y = 440 .....(1)

and

8x + 5y = 780 .....(2)

Multiply equation (1) by 2.

8x+6y = 880......(3)

Subtract equation (3) from (2).

8x + 5y -(8x+6y)= 780-880

-y = -100

y = 100

Put the value of y in equation (1).

4x+3(100) = 440

4x = 440-300

4x = 140

x = 35

Hence, the value of x is 35 and that of y is 100.

Hello! answer: 276

I dont know for sure though cause the model looks different from what I've seen before so answer at your own risk but I'm pretty sure this is right Hope that helps!

Ok so what I did was base × height for the rectangles because thats the formula for those those I got 70 for both the left and right the left isn't showing but I'm assuming its there its 70 for both because 14 × 5 = 70 then for the bottom is 112 because 14 × 8 = 112 then the two triangles are 12 each because 8 × 3 = 24 then divide by 2 because thats what you do for triangles then I just add all these numbers up so... 70 + 70 + 112 + 12 + 12 = 276

Answer:

5 days

Step-by-step explanation:

dogs, combined, eat 80 ounches of food daily

there are 16 ounces in one pound so there are 25x16, or 400 ounces, in a 25-pound bag

400/80 = 5

25-pound bag would last 5 days

One bag of dog food volunteered by Amelia, Which have quantity of 25 pounds  will last for 5 days.

What is ratio?

Ratio is mathematical term, which we use for comparing two or more terms. basically it indicates that how much big or small is number in compared to another.

Given that,

Every day, Amelia puts out 10 ounces of food for each of the 8 dogs.

Dog food comes in 25-pound bags.

And it is know that,

1 pound = 16 ounce;

so by that way it can state that,

Dog food for 25-pound bag will be equal to;

25*16

400 ounce.

Everyday requirement of dog food is 8*10 = 80 ounce/day

Number of days food will  last= Available quantity/Everyday requirement

Number of days food will  last= 400/80

Number of days food will  last= 5 days

Hence, One bag of food will be enough for 5 days.

Answer:

Stefan originally spent $ 110 on the bike and helmet, with which he is making a profit of $ 33.

Step-by-step explanation:

Since Stefan sells Jin a bicycle for $ 125 and a helmet for $ 18, and the total cost for Jin is 130% of what Stefan spent originally to buy the bike and helmet, to determine how much did Stefan spend originally and how much money did he make by selling the bicycle and helmet to Jin, the following calculations must be performed:

130 = 125 + 18

100 = X

100 x (125 + 18) / 130 = X

100 x 143/130 = X

14,300 / 130 = X

110 = X

143 - 110 = 33

Therefore, Stefan originally spent $ 110 on the bike and helmet, with which he is making a profit of $ 33.

Where the above is square, the coordinates are: (4, 7). This is obtained by simply tracing the A-D in equal distance with B and C.

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.

A coordinate system is a framework for specifying the relative positions of objects in a specific region, such as an area on the earth's surface or the whole earth's surface. A geographic coordinate system determines locations on the world by using a three-dimensional spherical surface.

The table in the exercise can be completed with the next results:

Step-by-step explanation:

As in the exercise Janice is 7 years older than Tam, to obtain the result in the table, you must add 7 to each age in the column x, with this we can make the next formula:

Remember that x is Tam's age, and y is Janice's age, so, you must replace the x variable in each case to obtain the result to y:

When x is 2:

When x is 4:

When x is 6:

When x is 8:

At last, to obtain the graph you can use the formula made: y = x + 7, and you'll obtain a graph like the attached picture, where each time x obtain a unit, the y variable obtain a unit too maintaining the diference of 7.

Answer:

1/6

Step-by-step explanation:

3 out of 18 marbles are green. 3/18 can be reduced to 1/6 because both 3 and 18 are divisible by 3.

3/3=1

18/3=6

1/6

The probability of picking a green marble is 1/6.

To find the probability of picking a green marble, we need to consider the total number of marbles and the number of green marbles in the jar. The jar contains a total of 18 marbles, and out of these, there are 3 green marbles.

The probability of an event happening is calculated by dividing the number of favorable outcomes (in this case, the number of green marbles) by the total number of possible outcomes (the total number of marbles in the jar).

So, the probability of picking a green marble can be written as:

P(green marble) = Number of green marbles / Total number of marbles

Substituting the values, we get: P(green marble) = 3 / 18

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 3. Dividing both 3 and 18 by 3, we get: P(green marble) = 1 / 6

Therefore, the probability of picking a green marble from the jar is 1/6. This means that if you randomly pick a marble from the jar, there is a 1 in 6 chance that it will be green.
