Mathematics
1 answer:
Scorpion4ik [409]4 years ago
3 0

x =  \frac{c - by}{a}
Ax+By=C
steps:
1) Subtract the By
Ax + By = C
–By = C – By
*Positive and Negative Cross Each Other Out*
Ax = C – By
2)divide by A
Ax = C – By
---- = ----------
A A
*A divided by A is one*

elena-s [515]

The chart relating to the question can be found in the picture attached below :

Answer:

40%

Step-by-step explanation:

Yoghurt __________ No of responses

Low Fat ___________ 15

Greek_____________24

Whipped __________ 10

Regular ___________ 11

Total number of responses :

(15 + 24 + 10 + 11) = 60

Number of  responses for Greek yogurts = 24

Percentage % :

(Greek Yoghurt responses / total responses) * 100%

= (24 / 60) * 100%

= 0.4 * 100%

= 40%

4.5/y = 12.5/4 PLEASE HELP!!! SOS
garik1379 [7]

Answer:

y = 1.44

Step-by-step explanation:

What are you aiming to do here?  Please share all instructions with each problem.

If you want to solve 4.5/y = 12.5/4 for y:  Multiply both sides by 4y:

18 = 12.5y.  Then y = 1.44

A car is driving down a long Steep Hill the elevation above sea level in feet of the car when it is D miles from the top of the
amid [387]

Answer:

This task would be especially well-suited for instructional purposes. Students will benefit from a class discussion about the slope, y-intercept, x-intercept, and implications of the restricted domain for interpreting more precisely what the equation is modeling.

One potential confusion students may have follows from the subtle difference between what the car is doing and the idea of slope as the ratio between the change in vertical distance on the graph and the change in horizontal distance on the graph. Because the car is traveling one mile on a down-hill slope, the situation could be represented as a right triangle with a hypotenuse of 5,280 ft and a leg of 250 ft; using the Pythagorean Theorem they would find that the other leg is approximately 5,274 ft. Following through on this interpretation, a student might conclude that the car travels a horizontal distance of approximately 5,274 ft for every 250 ft in vertical distance and arrive at a slope of approximately -0.047. While this is, in some sense, the slope of the hill, it is not the slope of the function as described. This interpretation yields numbers that are very close to the situation described in the task, yet conceptually different since the distance traveled by the car would now be expressed in terms of horizontal distance traveled as opposed to distance along the slope of the hill to compute the elevation. If students do indeed pursue this line of reasoning, the task provides an opportunity to compare and contrast the graph of the function and what it represents with a drawing of the hill and the vertical and horizontal distances traversed with each mile down the slope.

Horsepower and watts are units of measure of
Leni [432]

The 2 horsepower is equal to 1492 watts.

Given that horsepower and watts are units of measure of power and they are directly proportional such that 5 horsepower is equal to 3730 watts.

Horsepower is a unit of measurement of power, or speed at which work is done, usually related to the power of an engine or motor. power is calculated by multiplying force (in pounds) by  speed (in feet per second).

Let H= horsepower, W=watt

As we are given horsepower is directly proportional.

So, the relation is W=kH where k is constant.

Here, H=5 and W=3730.

By substituting the value of W and H we will find the value of k,  we get

3730=k×5

3730/5=k

746=k

Now, substituting the value of k in relation and we get

W=746H

We have to find the power of 2 horsepower.

So, we will substitute H=2 in above relation, we get

W=746×2

W=1492 watts.

Hence, the 2 horsepower is equal to 1492 watts when 5 horsepower is equal to 3730 watts.
