(2,57)(5,117)
slope = (117 - 57) / (5 - 2) = 60/3 = 20

y = mx + b
slope(m) = 20
(2,57)...x = 2 and y = 57
sub and find b, the y int
57 = 20(2) + b
57 = 40 + b
57 - 40 = b
17 = b

equation is : y = 20x + 17....with x being the number of minutes, and 17 being the number of boxes on the shelf when he started

<span>57 boxes of detergent on the shelves in 2 minutes
</span><span>After 5 minutes, he had put 117 boxes on the shelves

117 - 57 = 60 (60 </span>boxes of detergent for 3 minutes)
60/3 = 20 (20 boxes of detergent per minute)
so

20 x 5 = 100 boxes of detergent 

117 - 100 = 17 boxes

answer
17 boxes of detergent <span>were on the shelves when he started</span>

Machine A produces bolts at a uniform rate of 120 every 40 seconds, and Machine B produces bolts at a uniform rate of 100 every
Nutka1998 [239]

Answer:

25 seconds

Step-by-step explanation:

Hi there!

In order to answer this question, first we need to know how many bolts per second are produced by each machine, this can be known by dividing the number of bolts by the time it takes.

For machine A:

A = \frac{120 bolts}{40 s}= 3 \frac{bolts}{s}

For machine B:

B = \frac{100 bolts}{20 s}= 5 \frac{bolts}{s}

So, if the two machines run simultaneously, we will have a rate of prodcution of bolts equal to the sum of both:

A+B=(3+5)\frac{bolts}{s}=8\frac{bolts}{s}

Now, we need to know how much time it will take to producee 200 bolts, to find this out we need to divide the amount of bolts by the production rate:

t = \frac{bolts}{ProductionRate}= \frac{200 bolts}{8 \frac{bolts}{s} }

The <em>bolts</em> unit cancell each other and we are left with <em>seconds</em>

t = \frac{200}{8} s = 25 s

So it will take 25 seconds to produce 200 bolts with machine A and B running simultaneously.

Greetings!

A sheet of cardboard is 1.6 m by 0.8 m. The following shapes are cut from the cardboard: ● a circular piece with radius 12 cm ●
babymother [125]

Answer:

1.17m²

Step-by-step explanation:

Total area of cardboard=

1.6 \times 0.8 = 1.28m {}^{2}

Area of circular piece=

\pi \: r {}^{2}  = ( \frac{22}{7} )(0.12) {}^{2}  =  \frac{198}{4375} m {}^{2}

Area of rectangular piece=

0.2 \times 0.15 = 0.03m {}^{2}

Area of 2 triangular pieces=

2( \frac{1}{2} \times 0.3 \times 0.1) = 0.03m {}^{2}

Remaining area of the cardboard= Total area of cardboard - circular piece - 2 triangular pieces

1.28 -  \frac{198}{4375}  - 0.03 -0.03 =  \frac{21083}{17500}   =1.17m {}^{2}
