Simplify the complex number.
(8i) (5) (-4-6i)

Answer:

14 feet

Step-by-step explanation:

You find this answer by adding each side. The arrow tells us that each side of a square is 1 foot, so you add up the outer sides of each square

[tex]5y+2x = -7~~~~~......(i)\\\\y = -2x +5 ~~~~~~.....(ii)\\\\(i) -(ii):\\\\5y+2x -y = -7-(-2x+5)\\\\\implies 4y +2x = -7 +2x -5\\\\\implies 4y +2x -2x = -12\\\\\implies 4y = -12\\\\\implies y = - \dfrac{12}4 = -3\\\\\\\text{Substitute}~ y=-3~ \text{in equation (ii):}\\\\\\-3 = -2x +5\\\\\implies 2x = 5 +3 \\\\\implies 2x = 8\\\\\implies x = \dfrac 82 =4\\\\\text{Hence,}~ x = 4[/tex]

It will take 21.53 hours for 8 workers and 5 bandits to lay 1400 bricks.

Given that one worker can lay 10 bricks every hour, and one bandit steals 3 bricks every hour, to determine how long it would take 8 workers and 5 bandits to lay 1400 bricks, the following calculation must be performed:

Therefore, it will take 21.53 hours for 8 workers and 5 bandits to lay 1400 bricks.

Step-by-step explanation:

4x-3y=7y+2x

collect like terms

4x-3y-7y-2x=0

2x-10y=0

x-5y=0

rewrite it in slope intercept form

y=[tex]\frac{1}{5}[/tex]x which is the equation for a straight line

Step-by-step explanation:

Volume = length ×width × height

therefore

5cm× 6cm×2cm=volume

60cm³= volume

Volume = length ×width × height

1200mm³=20mm×10mm×H

1200mm³=200mm²×H

1200mm³/200mm²=200mm²/200mm²×H

6mm= H

Volume = length ×width × height

72m³=L×3m ×6m

72m³= L× 18m²

72m³/18m²= L×18m²/18m²

4m =L

Volume = length ×width × height

256cm³=8cm ×w×8cm

256cm³=64cm²×w

256cm³/64cm²=64cm²/64cm²×w

4cm=w

Volume = length ×width × Height

379.6m³=5.2m×7.3m×H

379.6m³=37.96m²×H

379.6m³/37.96m²=37.96m²/37.96×H

10m=H

Volume = length ×width × Height

288mm³=L×12mm×8mm

288mm³= L×96mm²

288mm³/96mm²= L×96mm²/96mm²

3mm=L

Answer: Neither A or B

Step-by-step explanation: In order for a relation to be a function, a relation can not have the x-values repeat. Y-values can repeat an infinite amount of times but x-values can only repeat 1 time in a given relation. In relation A, you have (2,-2), and (2,3) and relation B, you have (9,3), and (9,-3). You can also graph both of these relations and do a vertical line test with your pencil and see that it would cross more than once.

Hope this helps.

Answer:

Neither A nor B

Step-by-step explanation:

A function is a relation that has a unique x value for every y value. This means that the x-values will never repeat. So, to figure out if a list of coordinates is a function check the x-values. If they never repeat, then it is a function. However, in the case of both A and B, the x-values repeat. For, relation A the value 2 repeats, and for relation B the 9 value repeats. Therefore, neither are functions.

Answer:

182

Step-by-step explanation:

If the suit itself is originally 260 and it lowered by 30% of itself, then we need to find 30% of 260, which would be 78. Since we are lowering the price, we subract 260 - 78 and get 182 as our final answer.

Answer:

y = [tex]-\frac{1}{2} x[/tex] [tex]-\frac{1}{2}[/tex]

Step-by-step explanation:

solved using point-slope form

points given: (-5, 2) and (5, -3)

slope: [tex]\frac{-3-2}{5-(-5)} =\frac{-5}{10} =-\frac{1}{2}[/tex]

y = [tex]-\frac{1}{2}[/tex] x + b

insert x- and y- values of (-5, 2) and solve for b

2 = [tex]-\frac{1}{2}[/tex] (-5) + b

2 = 2.5 + b

subtract 2.5 from both sides

2 - 2.5 = 2.5 + b - 2.5

-0.5 = b

insert b- value

y = [tex]-\frac{1}{2} x[/tex] [tex]-\frac{1}{2}[/tex]

Answer:

The physical activity calculator helps calculate minutes of activity and breaks down the types of activities performed every week. The calorie calculator doesn’t keep track of all activities. However, it calculates calorie expenditure. A new calculator might be a combination of the two calculators. It’d be a two-step process. People would be able to enter their age, gender, weight, height, and any medical factors so that they can ensure that their calorie calculations are accurate. Then, they’d be able to track the calories expended each day for a week by adding their activities for the whole day, from sitting to exercising. This information would give them an accurate portrayal of calorie expenditure and estimated caloric requirement.

Step-by-step explanation:

For each pizza variety, Daniel can choose 18 different toppings. Therefore, for 23 pizza varieties, Daniel can choose from 23 * 18 = 414 different combinations of varieties and toppings.

For each pizza size, Daniel can choose from 414 different combinations of varieties and toppings. Therefore, for n pizza sizes, Daniel can choose from n * 414 = 3726 combinations

414n = 3726

divide both sides by 414 to isolate the n

n = 9

Answer:

10 bags for 5 litres of cream of ice cream.

2  bags of sugar will be needed.

Comparing quantities is the qualitative relation between two quantities which reflects the relative size of both the quantities.

here, we have,

It is given that,

600ml of  cream requires = 225g of sugar

⇒  1 ml of  cream requires = 225/600g of sugar

⇒ 5000ml of  cream requires = 225/600 * 5000g of sugar

                                                  = 1875g

                                                  =1.875 kg

Hence we see that , Sugar comes in 1kg bags.

Similarly, 1.875kg of sugar = 1kg bag + 0.875kg bag

⇒ 2 bags of sugar is needed.

Therefore, 2  bags of sugar will be needed.
