Henri is a equipment manager for a soccer team. He buys a new trailer to move some equipment, and the specifications read that t

he trailer can haul up to 800 lbs. In order to ensure that they do not have any problems, he decides that he wants to put no more than 95% of the weight limit on the trailer. He needs to load 4 goals each weighing 125 lbs, two team benches each weighing 75 lbs, and two boxes of miscellaneous equipment each weighing 50 lbs. To figure out if the trailer can transport all of this, Henri multiplies 4 x 125, adds 2 x 75, and finally adds 2 x 50. He then multiplies this total (750 lbs) by .95 and sees if this amount is less than 800. Is this correct?

Answer:

No; he should have multiplied 800 by .95 and made sure that the total weight of the equipment was less than that amount. Hope this helps :)

His total load is 4*125 + 2*75 + 2*50, which is 750

now, is that 750 95% of 800?

well 95% of anything is 95/100 * anything

thus, 95% of 800 is 95/100 * 800 or 0.95 * 800

now, is that less than more or equals to 750?  if it's, then  he's golden, because his load is less or equals to 95% of 800, if not, then he needs to cut down some

Tao uses elimination to solve the following system of linear equations. -2x+4y=162x+2y=8Which ordered pair is a solution to the
Alex_Xolod [135]

The correct answer is the first option.


If you want to use elimination, you can sum the two equations for example, so that the x's simplify:


(-2x+4y)+(2x+2y) = 16+8


6y = 24


y = 4


Plug this value for y in one of the equations to derive the value of x:


2x+2y=8 \implies 2x + 8 = 8 \implies x = 0


So, the solution is (x,y) = (0,4)

Mr. Mole left his burrow and started digging his way down at a constant rate. Time (minutes) Altitude (meters) 666 -20.4−20.4min
Juli2301 [7.4K]

Answer:

-6 meters.

Step-by-step explanation:

We have been given Mr. Mole left his burrow and started digging his way down at a constant rate.

We are also given a table of data as:

Time (minutes)     Altitude (meters)

6                                   -20.4

9                                   -27.6

12                                   -34.8

First of all, we will find Mr. Mole's digging rate using slope formula and given information as:

m=\frac{y_2-y_1}{x_2-x_1}, where,

y_2-y_1 represents difference of two y-coordinates,

x_2-x_1 represents difference of two corresponding x-coordinates of y-coordinates.

Let (6,-20.4) be (x_1,y_1) and (9,-27.6) be (x_2,y_2).

m=\frac{-27.6-(-20.4)}{9-6}

m=\frac{-27.6+20.4}{3}

m=\frac{-7.2}{3}

m=-2.4

Now, we will use slope-intercept form of equation to find altitude of Mr. Mole's burrow.

y=mx+b, where,

m = Slope,

b = The initial value or the y-intercept.

Upon substituting m=-2.4 and coordinates of point (6,-20.4), we will get:

-20.4=-2.4(6)+b

-20.4=-14.4+b

-20.4+14.4=-14.4+14.4+b

-6=b

Since in our given case y-intercept represents the altitude of Mr. Mole's burrow, therefore, the altitude of Mr. Mole's burrow is -6 meters.

Does anyone get this??
kirill115 [55]

Answer:

The distance from the feet to the wall is 9 ft

Step-by-step explanation:

Using trig,

We must use cosine to find the missing side.

The equation is cos 60 = \frac{adjacent}{18}

The cosine of 60 is 1/2

So, we multiply 1/2 by 18

to get 9

Hope this helps!

Branliest would really be nice!
