To solve this problem, we can begin by analyzing the graph and then eliminating incorrect answers. By looking at the graph, we can see that it has a positive correlation (the graph is increasing from left to right), which tells us that it has a positive slope. Using this knowledge, we can eliminate answer choices C and D, which both suggest equations with a negative slope (which would mean that the line was decreasing from left to right).

Next, we must analyze the slope. Answer A suggests that the slope is 3/2, meaning that the line rises 3 units for every 2 units it goes across. Answer B suggests that the slope is 1/2, meaning that the line rises 1 unit for every 2 units that it goes across. If we look at the graph, let's say at the point (0,3), the next closest point is 3 units up and 2 units across, which lets us know that the slope is positive 3/2.

Therefore, your answer is A. y = 3/2x + 3 (which is confirmed by the point we recognized, (0,3), which is the y-intercept of the equation).

Hope this helps!

A hot air balloon gets loose from its anchor the balloon operator is look at the balloon at an angle of inclination of 34. If th

masha68 [24]

Answer:

horizontal distance = 74.13 ft

Step-by-step explanation:

In order to solve this problem, we can start by drawing what the situation looks like. (see attached picture)

As we can see in the picture, we can build a right triangle with the balloon and the operator. We can use a trigonometric function so solve this. Specifically the tan function. We know that:

$tan \theta = \frac{opposite}{adjascent}$

in this case:

$tan \theta = \frac{h}{l}$

so we need to figure out what l is equal to. We can solve this equation for l, so we get:

$l=\frac{h}{tan \theta}$

and substitute the values given by the problem, so we get:

$l=\frac{50ft}{tan (30^{0})}$

which yields:

l=74.13 ft

Four families share a basket of 16 kilograms equally how many kilograms of apples does each family get?

alex41 [277]

Answer:

4 kg of apples

Step-by-step explanation:

Given that,

Number of families = 4

Weight of the basket of apples= 16 kg

We need to find how many kilograms of apples does each family gets. We can find it as follows :

Received = $\dfrac{16}{4}$ = 4 kg of apples

Hence, each family gets 4 kg of apples.

The amount of the tip each waiter receives after a wedding is inversely proportional to the number of waiters serving the event.

iogann1982 [59]

Answer:

The relationship between n and t is n*t=1200 (option d)

Step-by-step explanation:

Two quantities are inversely proportional if when multiplying (or dividing) one of them by a number, the other is divided (or multiplied) by the same number. That is, two magnitudes are inversely proportional if when one increases, the other decreases in the same proportion.

Given two variables, x and y, with an inversely proportional relationship, the product of both is always constant and equal to the coefficient of proportionality:

x*y=k

where k is the coefficient of proportionality.

This means that knowing the value of the proportionality coefficient and the value of a variable, the value of the other variable can be known through the quotient between the proportionality coefficient and the value of the known variable:

$y=\frac{k}{x}$

The amount of the tip "t" each waiter receives after a wedding is inversely proportional to the number of waiters "n" serving the event. The total amount for tips at a wedding was $1,200.Taking into account the aforementioned definition of inversely proportional quantities, this can be expressed by:

n*t=1200

The relationship between n and t is n*t=1200 (option d)
