Answers

Answer 1

Answer:

It would require 4 days.

Suppose That 8 Machines Can Complete A Certain Task In 9 Days. If There Are 18 Machines, How Many Days

Answer 2

If there are 18 machines. Then the number of days would it take for them to finish the same task will be 4 days.

What is Algebra?

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

Time is inversely proportional to the number of the machines.

T ∝ 1/M

If the proportionality is removed, then a constant k is introduced.

Suppose that 8 machines can complete a certain task in 9 days.

Then the amount of the total work that is k will be

k = 8 x 9

k = 72

If there are 18 machines.

Then the number of days would it take for them to finish the same task will be

T = 72 / 18

T = 4 days

The number of days would it take for them to finish the same task will be 4 days.

how many feet tall is the building

Answers

Answer:

Height of the building = 77 ft.

Step-by-step explanation:

Let the height of the building (AB) = h feet

It's given that height of a woman (ED) = 5 feet 3 inches

≈ 5 feet + [tex]\frac{3}{12}[/tex] ft

≈ 5.25 ft

Length of the shadow (BC) of the building = 55 ft

Length of the shadow (DC) of the woman = 45 in ≈ 3.75 ft

Since, both the triangles ABC and EDC are similar, their corresponding sides will be proportional.

By the property of similar triangles,

[tex]\frac{AB}{ED}= \frac{BC}{DC}[/tex]

[tex]\frac{h}{5.25}=\frac{55}{3.75}[/tex]

h = [tex]\frac{55\times 5.25}{3.75}[/tex]

h = 77 ft

Therefore, height of the building will be 77 ft.

The y intercept is when x=0

so (0, -7) is the y-intercept

-3/9

simplified is -1/3

slope is -1/3 and y intercept is (0, -7)

Colin invests £1100 into his bank account. He receives 5% per year simple interest. How much will Colin have after 6 years?

Answers

Answer:

£1430

Step-by-step explanation:

Given data

Principal =£1100

Rate= 5%

time = 6 years

The simple interest formula is

A=P(1+rt)

substitute

A=1100(1+0.05*6)

A=1100(1+0.3)

A=1100(1.3)

A=1100*1.3

A=£1430

Hence the balance is £1430

1) Ben has 15 coins, all dimes and quarters, worth $2.55. How
many dimes and how many quarters does Ben have?

Answers

Answer:

Ben has 8 dimes and 7 quarters.

Step-by-step explanation:

Given that:

Number of coins = 15

Worth of coins = $2.55 = 2.55 * 100 = 255 cents

Let,

x be the number of dimes

y be the number of quarters

According to given statement,

x+y=15 Eqn 1

10x+25y=255 Eqn 2

Multiplying Eqn 1 by 10

10(x+y=15)

10x+10y=150 Eqn 3

Subtracting Eqn 3 from Eqn 2

(10x+25y)-(10x+10y) = 255 - 150

10x+25y-10x-10y=105

15y=105

Dividing both sides by 15

[tex]\frac{15y}{15}=\frac{105}{15}\\y=7\\[/tex]

Putting y=7 in Eqn 1

x+7=15

x=8

Hence,

Ben has 8 dimes and 7 quarters.

Your friend has $80 when he goes to the fair. He spends $4 to enter the fair and $12 on food. Rides at the fair cost $1 25 per ride. Which function can be used to determine how much money he has left over after x rides?

Answers

Answer:

80m - (12+4) = x

Step-by-step explanation:

Hope this helps! I mean its self explanatory

Answer:

$38.75

Step-by-step explanation:

We can add up the amount he spent before he started riding and we'll get $16. Subtract 16 from 80 which is 64. $64 dollars divided by $1.25 would be 51.2. We round down because he can't ride more then 50 rides. He would be able to ride 51 rides with the money he has. Let's say he rode 20 rides and then left the fair. We would subtract 20 from 51 and get 31. After that we would multiply 31 by 1.25 and get $38.75. So he would have $38.75 dollars after he left the fair.
