The newer machine works at a unit rate of

(5400 cans) / (180 min) = 30 cans/min

while the older machine operates at

(5400 cans) / (217 min) ≈ 24.88 cans/min

So working together, the two machines work at a rate of about 54.88 cans/min. Producing 5400 cans would then take about

(5400 cans) / (54.88 cans/min) ≈ 98.39 min

Answer:

D = 80 degrees or (76+4) C And F are 70 i think

Step-by-step explanation:

Answer:

Step-by-step explanation:

3(x +2 ) = 18     {Use distributive property: a(b +c) =a*b + a*c}

3*x +3*2 = 18

3x + 6 = 18             {Subtract 6 from both sides}

     3x = 18- 6

     3x = 12          {Divide both sides by 3}

       x = 12/3

x = 4

Answer: C

Step-by-step explanation:

7.5, because |-7.5|= 7.5

If a negative number is in between these bars | | then it becomes a positive.

False

Step-by-step explanation:

A ratio is not necessarily a comparison between quantities with different units, quantities with the same units can be in a ratio in mathematics.

Answer:

x = 15

y = 25

Step-by-step explanation:

WV = NP

WX = NM

VX = PM

VX/PM = WV/NP

8/20 = 6/x

8x = 120

x = 15

WV/NP = WX/NM

6/15 = 10/y

6y = 150

y = 25

Answer:

110°

Step-by-step explanation:

Since angle B is 30° and the ratio of a to b is 2:1, multiply 30 by 2 to get the measure of angle a = 60°.

Since angles a is 60° And the ratio of a to c is 3:1, divide 60 by 3 to get the measure of angle c = 20°.

add them up:

60 + 30 + 20 = 110°

Answer:

B. 60

Step-by-step explanation:

There are a total of 200 students here, and 45% got Cs, to find how many got Cs, multiply 200 by 45%, or 0.45: 200*0.45 = 90, 90 people got Cs.

15%  got Ds, multiply 200 by 15%, or 0.15 to get 30, 30 got Ds

The amount who got Cs minus the amount who got Cs is 90 - 30 = 60, 60 more students got Cs than Ds

Answer:92.84

Step-by-step explanation: 39+27+13.5+13.5 because the two sides are longer than 12

The perimeter of the trapezium is 143.94 ft.

We have,

The perimeter of an isosceles trapezium can be found by adding the lengths of all four sides.

In this case, the trapezium has height = 12 ft and parallel sides of length 27 ft and 39 ft.

To find the length of the non-parallel sides we can use the Pythagorean theorem:

a² = (39 - 27/2)² + 12²

a² = 1440

a ≈ 37.95 ft

Therefore,

The perimeter of the trapezium is:

P = 27 + 39 + 2a

P ≈ 27 + 39 + 2(37.95)

P ≈ 143.9 ft

Rounding to the nearest hundredth place,

we get P ≈ 143.94 ft.

Thus,

The perimeter of the trapezium is 143.94 ft.

Answer:

One thousand

Step-by-step explanation:

Answer: one thousand

Step-by-step explanation:

A thousandth is one of a thousand equal parts of something. ... a dust particle weighing only a thousandth of a gram.

Answer:

The set of values are described below:

[tex]v = 25\,cm[/tex], [tex]w = 25^{\circ}[/tex], [tex]x = 25^{\circ}[/tex], [tex]y = 65^{\circ}[/tex] and [tex]z = 10\,cm[/tex].

Step-by-step explanation:

Since [tex]\triangle JPO \cong \triangle SMR[/tex], then [tex]OJ \parallel RS[/tex] and [tex]OP \parallel RM[/tex]. By Alternate Internal Angles, we find that [tex]\angle R \cong \angle O[/tex]. In addition, the sum of internal angles in triangles equals 180°. Then, we have the following system of linear equations:

[tex]m\angle R + m\angle M + m\angle S = 180^{\circ}[/tex] (1)

[tex]m \angle O + m \angle P + m\angle J = 180^{\circ}[/tex] (2)

[tex]m\angle S = 65^{\circ}[/tex] (3)

[tex]m \angle M = m\angle P = 90^{\circ}[/tex] (4)

The solution of this system is [tex]m\angle R = 25^{\circ}[/tex], [tex]m \angle O = 25^{\circ}[/tex] and [tex]m \angle J = 65^{\circ}[/tex].

Lastly, the remaining sides are found by definition of congruence

Segment RS

Since [tex]\triangle JPO \cong \triangle SMR[/tex], then [tex]\overline {RS} \cong \overline {OJ}[/tex]. Hence, [tex]RS = 25\,cm[/tex]

Segment JP

Since [tex]\triangle JPO \cong \triangle SMR[/tex], then [tex]\overline{SM} \cong \overline {JP}[/tex]. Hence, [tex]JP = 10\,cm[/tex]

The set of values are described below:

[tex]v = 25\,cm[/tex], [tex]w = 25^{\circ}[/tex], [tex]x = 25^{\circ}[/tex], [tex]y = 65^{\circ}[/tex] and [tex]z = 10\,cm[/tex].

Answer:

The average speed of the entire trip is 8.5 miles per hour.

Step-by-step explanation:

Speed = Total  Distance / Total Time

So we have to find the total distance and the total time taken .

1) From Gujranwala to Daska

speed= 25miles/hour           distance = 15miles

Time taken = distance / speed

                   = 15/25= 0.6 hours

2)  From Daska to Sialkot

speed= 40miles/hour           distance = 15miles

Time taken = distance / speed

                   = 40/15= 2.67 hours

3 ) From  Sialkot to Daska

speed= 30miles/hour           distance = 15miles

Time taken = distance / speed

                   = 30/15= 2 hours

The total distance traveled to three places is = 15+ 15+15= 45miles

The Total time taken is = 0.6+ 2.67+ 2= 5.267=5.3 hours

Speed = Total  Distance / Total Time

Speed= 45/ 5.3

          = 8.49=8.5 miles per hour

The average speed of the entire trip is 8.5 miles per hour.

Answer:

1

Step-by-step explanation:

Answer:

Step-by-step explanation:

In mathematics, every integer is a rational number, hence a whole number 6 can be written as 6/1. 1/3 ÷ 6 = 1/18 in fraction form. 1/3 ÷ 6 = 0.0556 in decimal form.

Answer:

1/18 or 18 is your answer.

Step-by-step explanation:

Since 1/3 is already in fraction form, we will now turn 6 into fraction form.  Which is 1/6. Now we will put it into the equation 1/3 x 1/6 = 1/18.  The fraction 1/18 can also be 18.  Therefore, 18 or 1/18 is our answer.

Part A

Let's say we measure a board length and we measure 18.639 cm. Now let's say we round to the nearest tenth. That would lead to 18.6 cm. The question is "What is the largest value we can measure such that we round to the nearest tenth to get 18.7 cm?"

Well we could measure 18.7 cm exactly, but there are values we could measure that are larger to round to that value. We could measure 18.71 or 18.72, etc etc all the way up to 18.74; once we get to 18.75, it will round to 18.8

So this means that the largest we can measure is 18.74 and it is the upper bound we're after.

=========================================================

Part B

We use the same idea as part A, but now we're extending out one more decimal place.

We could measure 58.37 cm exactly or we could measure 58.371 or we could do 58.372, etc until we arrive at 58.374

By the time we get to 58.375, it will round to 58.38 and that's not what we're after. So the highest we can go is 58.374 cm

Hope this helps you with your question.

Answer:

For f(x) = √(2·x + 2) - √(x + 18), at f(x) = -1 the possible x-values includes;

-0.757, -17.5

Step-by-step explanation:

Given that the function is f(x) = √(2·x + 2) - √(x + 18)

The value of 'x' when f(x) = -1, is given as follows;

-1 = √(2·x + 2) - √(x + 18)

-1² = (√(2·x + 2) - √(x + 18))² = 3·x + 20 - 2·√(2·x + 2)×√(x + 18)

1 = 3·x + 20 - 2·√(2·x + 2)×√(x + 18)

2·√(2·x + 2)×√(x + 18) = 3·x + 20 - 1 = 3·x + 19

2·x² + 38·x + 36 = (3·x + 19)/2

2·x² + 38·x + 36 - (3·x + 19)/2 = 0

4·x² + 73·x + 53 = 0

From which we get;

x = (-73 ± √(73² - 4 × 4 × 53))/(2 × 4)

x ≈ -0.757, and x ≈ -17.5

Hi!

ok so the Pythagorean theorem is

[tex]c=\sqrt{x} a^2+b^2=\sqrt{x} 8^2+6^2=10[/tex]

so the other side is 10.

the square 8 is 8*8

and square 6 is 6*6

so the other square is 10*10=100.

so the area of the blank square is 100.
