Mrs. Vacarro sliced a banana into 5 pieces. After eating one slice, she gave ⅘ of the original total to her toddler. After her child was finished, there were ⅖ of the banana slices left. What expression would you use to find out what fractional amount of banana Mrs. Vacarro's toddler ate?

Answers

Answer 1
Answer : the toddler ate 2/5 pieces

Explanation: there were 5 existing pieces, mrs. Vacarro had 1 and gave the rest to her toddler which were 4 pieces. The remaining pieces were 2 which means the toddler ate 2/5 pieces
Answer 2

The fractional amount of banana Mrs. Vacarro's toddler ate is 2/5.

What is a word problem?

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

Mrs. Vacarro sliced a banana into 5 pieces.

Number of slices she gave to her toddler = 4/5

Number of slices left after her toddler had finished eating = 2/5

Thus number of slices toddler ate,

⇒ [tex]\frac{4}{5} -\frac{2}{5}[/tex]

⇒ [tex]\frac{4-2}{5}[/tex]

⇒ [tex]\frac{2}{5}[/tex]

Hence we can conclude that the fractional amount of banana Mrs. Vacarro's toddler ate is 2/5.

What is simple interest?

Simple interest is a quick and easy method of calculating the interest charge on a loan.

What is the formula for calculating the simple interest?

The formula for calculating the simple interest is

[tex]Simple\ interest = \frac{P\times R\times T}{100}[/tex]

Where,

P is the principal amount

R is the interest rate

And, T is the time in years

According to the given question.

Principal amount, P = $18,000

Interest rate, R = 6.8%

Time, T = 4 years

Therefore,

The monthly loan payments, we calculate the simple interest for monthly

= [tex]\frac{18000 \times 6.8\times 4}{100 \times 12}[/tex] = $408

Tatia, Mary, and Erica were partners in business. Tatia received twice as much of the profit as Erica received. Mary received 2/3 of the amount Tatia received. If the total profit was $52,000, how much did Mary recieve

Answers

Answer:

$16000

Step-by-step explanation:

let Amount Erica received be 'x'

Tatia received = 2x

Mary received = 2/3(2x) = 4x/3

x + 2x + 4/3(x) = 52000

3x + 4x/3 = 52000

(9x+4x)/3 = 52000

13x/3 = 52000

x = (52000 x 3) / 13

x = 4000 x 3

x = 12000

Mary Received = 4x/3 = 4(12000)/3 = 16000

Answer:

$16000

Step-by-step explanation:

erica would get -n

tatia gets -2n

Mary gets -2/3 of 2n

2n +( 2/3 of 2 n ) + n =$52000

2n + 4/3n+ n=$52000

3 4/3 n=$52000

13/3 n= $52000

n= $16000

find the interior angle sum for the following polygon.​

Answers

We know that the interior angle sum of a polygon is (n − 2) × 180°, where n is the number of sides.

Here, number of sides (n) = 12

So, interior angle sum = (n − 2) × 180°

=> interior angle sum = (12 - 2) × 180°

=> interior angle sum = 10 × 180°

=> interior angle sum = 1800°

So, the interior angle sum of this polygon is 1800°.

Answers

Answer:

1) 800 (read the both) 2) 2200 (read exactly one)

Step-by-step explanation:

Find the people (families) who read neither of them

4000/100*25= 1000

It means that the rest 4000-1000= 3000 families read the newspapers at least  in one language  from the pointed languages. 4000/1oo*50= 2000 - readers in Nepali

4000/100*45= 40*45=1800 - readers in English.

2000+1800= 3800- the special amount, that consists of 1) only Nepali readers

2) only English readers 3) the readers in two languages (but the were counted twice, because we considered them in the group of Nepali readers and group of English readers)

The real quantity of only Nepali readers, only English readers and both language readers is 3000.

Step-by-step explanation:

The question is not properly formatted (see attachment for the frequency table and the options)

Required

The conditional relative frequency table by column

We have:

[tex]\begin{array}{cccc}{} & {Looking\ for\ job} & {Not\ looking} & {Total} & {Employed} & {12} & {28} & {40} & {Not\ Employed} & {38} & {72} & {110}& {Total} & {50} & {100} & {150} \ \end{array}[/tex]

To get the conditional frequency by column, we simply divide each cell by the corresponding total value (on the last row)

So, we have:

Find the first term and the common difference of the arithmetic sequence whose 6th term is 30 and 12th term
is 54.

Answers

Answer:

10 and 4

Step-by-step explanation:

The first term is a, common difference is d.

The 6th term:

a + 5d = 30

The 12th term:

a + 11d = 54

Solve the system by elimination:

11d - 5d = 54 - 306d = 24d = 4

Find a:

a + 5*4 = 30a + 20 = 30a = 10

Answer:

Given :-

6th term = 30

12th term = 54

To Find :-

First term

Common difference

Solution :-

We know that

[tex] \sf \: a_{n} = a + (n - 1)d[/tex]

For 6th term

[tex] \sf \: 30 = a + (6 - 1)d[/tex]

[tex] \sf \: 30 = a + 5d[/tex]

For 12th term

[tex]\sf \: a_{n} = a + (n - 1)d[/tex]

[tex] \sf \: 54 = a + (12 - 1)d[/tex]

[tex] \sf \: 54 = a + 11d[/tex]

On subtracting both

[tex] \sf \: 54 - 30 = a + 11d - (a + 5d)[/tex]

[tex] \sf \: 54 - 30 = a + 11d - a - 5d[/tex]

[tex] \sf \: 24 = 6d[/tex]

[tex] \sf \: \dfrac{24}{6} = d[/tex]

[tex] \sf \: 4 = d[/tex]

Now

Using 2

[tex] \sf \: 54 = a + 11d[/tex]

[tex] \sf \: 54 = a + 11(4)[/tex]

[tex] \sf \: 54 = a + 44[/tex]

[tex] \sf \: 54 - 44 = a[/tex]

[tex] \sf \: 10 = a[/tex]

Answer:

0 and 4

Step-by-step explanation:

The roots of the quadratic equation whose related function is graphed are 0 and 4, the correct option is C.

What is the quadratic equation?

A quadratic equation is a second-order equation written as ax2 + bx + c = 0 where a, b, and c are coefficients of real numbers and a ≠ 0.

If b2 – 4ac > 0 roots are real and different. As the discriminant is >0 then the square root of it will not be imaginary. It has two cases.

If b2 – 4ac is a perfect square then roots are rational. As the discriminant is a perfect square, so we will have an integer as a square root of the discriminant. Hence, the roots are rational numbers.

The shape of the graph is a downward parabola on the positive x-axis therefore the roots of the graph are positive.

From the given option the roots of the equation are 0 and 4 both are positive.

Hence, the roots of the quadratic equation whose related function is graphed are 0 and 4.
