heather spend 2/7 of her money buying presents. she then had €48.65 left how much had she at first?
Given :
Heather spend 2/7 of her money buying presents.
She then had €48.65 left.
To Find :
The initial amount of money she had.
Solution :
Let, initial amount she had is €x.
So,
[tex]x - \dfrac{2x}{7} = 48.65\\\\\dfrac{5x}{7} = 48.65 \\\\x = \dfrac{48.65\times 7}{5}[/tex]
x = €68.11
Therefore, initially he had €68.11 .

At a bagel shop the first 6 bagels purchased cost 55 cents apiece, and additional bagels cost c cents apiece. If a customer paid $5.70 for 12 bagels, what is the value of c?
Answer:
C = 0.475
Step-by-step explanation:
you divide 5.70 by 12 and get that one bagel costs 0.475 cents. hope this helps!
c=40 is the answer
6x55=330 cents
$570-570 cents (570-330)÷(12-)
=240÷6 (division)
=40 cents
Thus, c=40
What is the unitary method?The unitary method is a method for solving a problem by first finding the value of a single unit and then multiplying the value of a single unit to find the required value.
The unitary method is a procedure that calculates the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Simply put, the unitary method is used to find the value of a single unit from a given plural. For example, if the price of 40 pens is 400 rupees, the price of one pen would be: This can be done using a uniform method

The top of the cliff is 142 m above sea level. Currently the boat is 100 metres from the buoy and the angle of depression from the top of the cliff to the boat is 64º. Find the distance from the top of the cliff to the buoy. diagram not to scale Top of cliff 142 boat buoy Base of cliff (sea level) 100 m. The distance from the top of the cliff to the buoy is type your answer...
Answer:
221.0 m
Step-by-step explanation:
First, find x using trigonometric ratio formula:
Reference angle = angle of depression = angle of elevation = 64°
Opposite side length = 142 m
Adjacent side length = x
Thus:
tan(64) = 142/x
x*tan(64) = 142
x = 142/tan(64)
x = 69.3 (nearest tenth)
Next, find distance from top of the hill to the buoy using Pythagorean Theorem.
Let the distance be y.
We would have:
y² = 142² + (69.3 + 100)²
y² = 20,164 + 28,662.49
y² = 48,826.49
y = √48,826.49
y = 221.0 m (nearest tenth)

The time a student sleeps per night has a distribution with mean 6.06 hours and a standard deviation of 0.55 hours. Find the probability that average sleeping time for a randomly selected sample of 35 students is more than 6.15 hours per night.
Answer:
The probability is 0.16602
Step-by-step explanation:
We start by calculating the z-score
We have this mathematically as;
z-score = (x-mean)/SD/√n
From the question,
we have x = 6.15
mean = 6.06 hours
standard deviation = 0.55 hours
n = 35
Substituting these values, we have
z-score = (6.15-6.06)/0.55/√35
z-score = 0.09/0.55/5.92
z-score = 0.97
So the probability we want to calculate is:
P ( z > 0.97)
we make use of the standard normal distribution table here
The value is; 0.16602
Which expression is equivalent to (7 - 3k) - (4 - 5k) - (6 - 2k)?
A. -10k - 3
B. -4k + 3
C. 4k - 3
D. 10k + 3
Answer:
C. 4k-3
Step-by-step explanation:
Step 1: Remove parentheses.
7-3k-4+5k-6+2k
7−3k−4+5k−6+2k
Step 2: Combine like terms.
(7-4-6)+(-3k+5k+2k)
(7−4−6)+(−3k+5k+2k)
Step 3: Simplify.
-3+4k
Step 4: Regroup terms.
4k-3
I hope this helps!
A brainliest will be appreciated.
Answer:
C. 4k - 3.
Step-by-step explanation:
(7 - 3k) - (4 - 5k) - (6 - 2k)
Distributing the negative over the last 2 parentheses:
= 7 - 3k - 4 + 5k - 6 + 2k
= -3k + 5k + 2k + 7 - 4 - 6
= 4k -3.

Devante has a lunch account in the school cafeteria His starting balance at the beginning of the month is $35.50. The first wook, Davante bought 3 lunches and his account balance was $28.00. The second week. Devante
bought 5 lunches and his account balance was 515 50
In a model that relates the balance of his lunch account as a function of the number of lunches he buys, what does the rate of change represent?
A: the number of lunches he purchases
B: the starting balance of his lunch account
C: the amount of money in his lunch account
D: the amount of money he pays for each lunch
Answer:
D the amount of money he pays for each lunch
Step-by-step explanation:
In each lunch Devante has, he pays 2,50 $ according to:
Money in t = t₀ he has 35,50 $ paid 3 lunches and spent
35,50 - 28 = 7,5
Then the cost of each lunch is 7,5 / 3 = 2,5 $
After that
bought 5 lunches and spent 28 - 15,5 = 12,50
Again 12,5 / 5 = 2,5 $
Now the model for the situation is a straight line with a slope 2,5
In an x , y cartesian system in which y is money in the account and x is the number of lunches, such a straight line will be
y = b - m*x ( b the intercept on y and m the negative slope)
y = 35,50 - 2,5*x
So answering the question is lyrics D the amount of money he pays for each lunch

: Many of our folk songs serve a purpose. Do you think that nursery songs could be considered folk music? Why or why not?
Answer:
In many instances, the lyrics to folk songs came from existing nursery rhymes or poems, and some of the nursery rhymes had variations, depending on region or time. Thus, these folk songs may have lyrics that are slightly different from those you are familiar with.
Therefore, in my opinion, I think that Nursery songs can be considered folk music.

At the grocery store you choose to buy 4 items that cost: $2.69, $14.45, $8.05, and $13.95. Estimate the total cost of your groceries by rounding the cost of each item to the nearest dollar. What is the estimated total?
Answer:
$39
Step-by-step explanation:
First, let's get the values of each number by rounding them off to the nearest dollar before adding them.
Remember that you have to round off the number up if it is being followed by a number equivalent to 5 and above. You have to retain the number if it is followed by a number less than 5.1. $2.69 = $3
2. $14.45 = $14
3. $8.05 = $8
4. $13.95 = $14
Now that you have the rounded off numbers, you may add them.
Let's solve.
$3 + $14 + $8 + $14 = $39The estimated total is $39.
There are only blue cubes, red cubes and yellow cubes in a box.
The number of red cubes in the box is the same as the number of yellow cubes in the box.
a) Complete the table
There are 30 blue cubes in the box.
b) What is the total number of cubes in the box?
Total probability equals 1.
Subtract the probability of blue from 1:
1-0.4 = 0.6
Red and yellow total is 0.6
Since they have the same number of cubes, the probability of both would be the same so divide the remainder by 2:
0.6 /2 = 0.3
The probability of red is 0.3
The probability of yellow is 0.3
30 blue cubes with a probability of 0.4.
Let total cubes = x
30 blue/ x = 0.4
Multiply both sides by x:
30 = 0.4x
Divide both sides by 0.4
X = 30/0.4
X = 75
Total cubes is 75
This doesn’t make sense though because red and yellow are supposed to be the same and if you subtract blue from total it’s an odd number so red and yellow aren’t the same:
75-30 = 45
45/2 = 22.5
Which of the following correctly uses the additive inverse property
Step-by-step explanation:
-6÷-30=1/6÷1/30
1/6×30/1
