The sum of two numbers is 956. One is 94 less than 6 times the other. write an equation for the first sentence and second. Then

Setler79 [48]

Answer:

Step-by-step explanation:

suppose the first one is x. so the other one should be 6x-94 (as said).

so : x+6x-94 = 956 . then 7x -94 = 956 . then 7x = 1050 . so x = 1050/7 . then

x = 150

A drone is monitoring the atmospheric conditions above a farm field.

Viefleur [7K]

Answer:

$y=5 \ \ \ x x_o + 1.9s$

Step-by-step explanation:

This situation can be considered as a piecewise function. First, you take xo as the time in which the drone goes upward. Before this time the height of the drone is constant with a value of 5 m. Next, you take into account that during 1.9 s after xo the drone accelerates. Finally, the drone flies again with a constant height of 5.9m. Hence, this function has three parts:

For the first part you have:

y = 5 for x < xo

For the second part you first calculate vertical speed (which means the slope of the linear function) by using the following kinematic equation:

$y=vx\\\\v=\frac{y-y_o}{x}=\frac{5.9m-5.0m}{1.9s}=0.47m/s$

Then you have:

y = 0.47x for xo < x < xo + 1.9s

And for the third part:

y = 5.9 for x > xo + 1.9s

Summarizing you obtain:

$y=5 \ \ \ x x_o + 1.9s$

The greatest integer less than or equal to the given number; it is expressed: [[x]]. These are sometimes called step functions.

sergiy2304 [10]

Answer:

I think its, 5

Step-by-step explanation:

Becaus you take that number and its axcelerated calculation would be 5 in axis square root which is 3 and obviously 3+2 =5 so the wuarterining calculas is 5.

You are running a concession stand at a basketball game. You are selling hot dogs and sodas. Each hot dog costs $2.25 and each s

baherus [9]

The equations and the number of hotdogs and sodas sold are: x+ y = 126 and 2.25x + 1.50y = 225.75 ; 49 hot dogs and 77 sodas.

Two equations can be derived from this question:

2.25x + 1.50y = 225.75 equation 1

x + y = 126 equation 2

Where:

x = number of hotdogs sold

y = number of soda sold

In order to determine the value of y, multiply equation 2 by 2.25

2.25x + 2.25y = 283.50 equation 3

Subtract equation 1 from 3

57.75 = 0.75y

y = 77

Substitute for y in equation 2

x + 77 = 126

x = 49
