The total cost for all chains produced in 10 minutes will be $303.14.

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

An industrial factory makes 4 ³/₅ yards of chain every minute. Then the rate is given as,

Rate = 4 ³/₅

Rate = 4 + 3/5

Rate = 4 + 0.60

Rate = 4.60 yards per minute

The cost of each yard is $6.59. Then the cost per minute is given as,

⇒ $6.59 x 4.60

⇒ $30.314 per minute

Then the total cost for all chains produced in 10 minutes will be given as,

⇒ $30.314 x 10

⇒ $303.14

Answer:

£6

Step-by-step explanation:

The computation of the each parent pay is shown below;

But before that the cost of hall after considering the discount is

= £200 - 10% of £200

= £200 - £20

= £180

Now there are 30 parents

So each parent pay is

= £180 ÷ 30 parents

= £6

Answer:

3 cups flour

Step-by-step explanation:

set up a proportion and cross-multiply:

1/4 = 1/2

3/2      f

1/4f = 3/4

4f = 12

f = 3

Answer:

3 cups

Step-by-step explanation

basically if 1/4 cup of milk is for 1 1/2 cups of flour ------ 1/2 cup is twice the amount that a quarter cup is because a 1/4 cup + a 1/4 cup = 1/2 cup so you double the amount of flour too and 1 1/2 + 1 1/2 is 3 cups of flour.

1/4 + 1/4 = 1/2 (milk)

1 1/2 + 1/12 = 3 (flour)

Answer:

5/11 or 45 percent, since there are 5 blue cards

The probability that Isabella will take a blue card is 5/11.

Probability is the chance that something will happen, or how likely it is that an event will occur.

P(E) = total number of favorable outcomes/ total number of outcomes

Where,

P(E) is the probability of any event.

According to the given question

Five blue cards, two green cards and four red cards.

⇒ total number of outcomes =  5+ 2 + 4 = 11

For finding the probability of blue card

Total number of blue cards is 5.

⇒ total number of favorable outcomes = 5

Therefore,

The probability of getting blue card

= number of favorable outcomes/ total number of outcome

= [tex]\frac{5}{11}[/tex]

Hence, the probability that Isabella will take a blue card is 5/11.

Answer:

y - 7 = - [tex]\frac{5}{2}[/tex] (x + 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - [tex]\frac{5}{2}[/tex] and (a, b ) = (- 2, 7 ) , then

y - 7 = - [tex]\frac{5}{2}[/tex] (x - (- 2) ) , that is

y - 7 = - [tex]\frac{5}{2}[/tex] (x + 2)

Answer:90

Step-by-step explanation:

The distance between these cities on the map is 90 mm.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Cincinnati is about 225 miles from Cleveland and on scale 10 millimetres is equal to 25 miles.

The distance on the map will be calculated as,

25 miles = 10 mm

1 mile = 10 / 25 mm

225 miles = ( 225 x 10 ) / 25

225 miles = 90 mm

Therefore, the distance between these cities on the map is 90 mm.
