Answer:

Step-by-step explanation:

A. For this case, the first thing we must do is define variables.

We have then:

t: time in minutes

The linear equation that represents the problem is given by:

w (t) = (1/4) t + 11.25

Answer:

An equation for W in terms if T is:

w (t) = (1/4) t + 11.25

B. Answer:2 .25 Tons

Step-by-step explanation:

Weight of truck + sand when filled= 18 tons

Discharge rate per minute= 1/8 tons/ minute

Quantity of sand in the truck will be:

1/8tons per minute×18tons = 9/4 = 2.25tons

kifflom [539]

You are correct that the slope of line AB is 2. To find the slope of the line CD, we can apply the slope formula again (like I assume you did with AB).

m=\frac{15-7}{4-0}=\boxed{2}

Therefore, since the slopes of lines AB and CD are equal, they are <u>parallel</u>

Can you please help with math

Interpret the exponent in the formula. S to the third power means to use s as a factor 3 times.

 V = S to the third power = S x S x S

Find the volume of the first cube.
Substitute 4 for s.

V = 4 x 4 x 4 = 64

Find the volume of the second cube.
Substitute 7 for s.

V = 7 x 7 x 7 = 343

Tamara's first cube has a volume of 64 cubic centimeters, and her second cube has a volume of 343 cubic centimeters

Hugo and Viviana work in an office with eight other coworkers. Out of these 10 workers, their boss needs to choose a group of fo
Doss [256]

Answer:182 ways

Step-by-step explanation:

Given

there are total of 10 workers in office

No of ways to select 4 workers out of 10 workers =^{10}C_4

=\frac{10\times 9\times 8\times 7}{4\times 3\times 2\times 1}=210

(b)If hugo and Viviana refuse to work together then

then no of ways in which hugo anf Viviana work together

=^{8}C_2=28

Therefore total no of ways in which Hugo and Viviana do not work together is =210-28=182\ ways

What is the equation, in point-slope form, of the line that is parallel to the given line and passes through the point (0,-1)
AfilCa [17]

Answer: in your case, point slope form will be y+1 = (the parellel slope or M)(x-0)

Step-by-step explanation:

basically the point slope form is suppose to be y - (y coodinate) = (M or slope)(x - (x coodinate) )

Parellel lines are the slope is the same, but the coordinates aren't

eg.    what is the equation, in point slope form, of the coordinate of a line (3,4) that is parellel to the equation: y = 3/4x + 6

no. 1: slope is 3/4

no. 2 plug all info into the equation: y - (y coodinate) = (M or slope)(x - (x coodinate) )

no.3 you have your equation! y - 4 = 3 / 4 ( x - 3 )
