An electrician has 4.1 meters of wire how many strips 7/10 m can he cut . How much wire will he have left

1 answer:

8 0

7/10 m= 0.7 m

4.1÷0.7=5.85

You would round down 5.85 to just 5, because he cannot cut less than a whole strip.

To find the exact amount of wire used in 5 strips:

5×0.7= 3.5

4.1-3.5= 0.6 m will be leftover.

Jill, Meg and Beth are sister's. Jill is 2 years younger than Meg. Beth is half as old as Meg. Let m represent Meg's age. Write

pshichka [43]

Answer:

Two other algebraic expressions based on this situation are:

$J = m-2$

$B = \frac{m}{2}$

Step-by-step explanation:

Let m represent Meg's age.

Jill is 2 years younger than Meg.

Let J represents Jill's age

Jill's age $J = m-2$

Beth is half as old as Meg

Let B represents Beth's age

Beth's age $B = \frac{m}{2}$

So, two other algebraic expressions based on this situation are:

$J = m-2$

$B = \frac{m}{2}$

Liam's breakfast was an egg and cheese biscuit with a carton of milk. He spent a total of $5.65. Finn spent $7.65 on an egg and

ruslelena [56]

Answer:

An egg and cheese biscuit was $3.65.

Step-by-step explanation:

Liam's breakfast was:

$P = E + C + M$

Where:

P: total price

E: egg

C: cheese biscuit

M: carton of milk

$P = E + C + M$

$5.65 = E + C + M$ (1)

Now, Finn's breakfast was:

$P = E + C + 2*M$

$7.65 = E + C + 2*M$ (2)

By subtracting equation (2) from (1) we have:

$7.65 - 5.65 = 2M - M$

$M = 2$

Hence, the price of a carton of milk is $2, so by entering this value into equation (1) we can find the price of an egg and cheese biscuit:

$5.65 = E + C + M$

$5.65 - 2 = E + C$

$E + C = 3.65$

Therefore, an egg and cheese biscuit was $3.65.

I hope it helps you!

Reptile [31]

Answer:

Step-by-step explanation:

Given:

Annuity at time (n + 1) = 13.776

(1 + i)ⁿ = 2.476

Now,

$S_{n/i}=\frac{(1+i)^n-1}{d}$

here, d = $\frac{i}{1-i}$

thus,

$13.776=\frac{2.476-1}{d}$

d = 0.1071

therefore,

d = $\frac{i}{1+i}$

0.1071 = $\frac{i}{1+i}$

0.1071 + 0.1071i = i

i = 0.1199

now,

(1 + i)ⁿ = 2.476

(1 + 0.1199)ⁿ = 2.476

1.1199ⁿ = 2.476

taking log both sides

n × log(1.1199) = log(2.476)

n = 8.006 ≈ 8

hence,

the answer is 8
