A collector has 2792 coins
altogether. Half of the coins
are on display. The collector
buys more coins at an auction
so that the coins on display
are now 40% of the collection.
How many coins are bought at
the auction?

Answers

Answer 1

Answer:

3490 coins

Step-by-step explanation:

Given data

Total coins= 2792 coins

Half of the coins are on display

that is 50% are on display

=2792/2

=1396

let the coins bought be x

40% of x= 1396

40/100*x= 1396

0.4x= 1396

x=  1396/0.4

x=3490

Hence 3490 coins were bought

Find an equivalent fraction to 5/6 only.

Answers:
A) 2/4
B) 10/12
C) 11/6
D) 20/24
E) 50/60

Answers

B), D), and E) are all equivalent fractions to 5/6.
2/4 isn’t because simplified it equals 1/2
11/6 isn’t because it cannot be simplified further
10/2 = 5 and 12/2 = 6, which is why B) is one of the answers
20/4 = 5 and 24/4 = 6, which is why D) is another answer
50/10 = 5 and 60/10 = 6, which is why E) is the third answer

Answer:

B D and E

Step-by-step explanation:

Remark

It's hard to know how to tackle this. I suppose  the easiest way is to divide the numerator and denominator by a common factor.

2/4

The common factor is 2

Divide the 2 by 2 and the 4 by 2

2/2 = 1

4/2 = 2

The fraction reduces down the 1/2 which is not 5/6

10 / 12

The common factor is 2.

10/2 = 5

12/2 = 6

Looks like this is your answer. But is it the only one.

11/6

These two have no common factor. The answer is 11/6 which is not 5/6

20 / 24

The common factor of these two is 4

20/4 = 5

24/ 4 = 6

This is also = to 5/6

50 / 60

The common factor is 10

50/10 = 5

60/10 = 6

That's equal to 5/6 as well.

amy borrowed money from the lending company at 6% interest if she paid an interest of php450.00 after 19months how much money did she borrow​

Answers

Answer:

She borrowed php4737.00.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

[tex]E = P*I*t[/tex]

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

[tex]T = E + P[/tex]

6% interest:

This means that [tex]I = 0.06[/tex]

19 months:

An year has 12 months, so [tex]t = \frac{19}{12} = 1.5833[/tex]

She paid an interest of php 450. How much money did she borrow​

This is P when [tex]E = 450[/tex]. So

[tex]E = P*I*t[/tex]

[tex]450 = P*0.06*1.5833[/tex]

[tex]P = \frac{450}{0.06*1.5833}[/tex]

[tex]P = 4737[/tex]

She borrowed php4737.00.

Answer:

110

Step-by-step explanation:

3x+5+2x=180

Step 1: Simplify both sides of the equation.

3x+5+2x=180

(3x+2x)+(5)=180(Combine Like Terms)

5x+5=180

5x+5=180

Step 2: Subtract 5 from both sides.

5x+5−5=180−5

5x=175

Step 3: Divide both sides by 5.

x=35

35*3+5=110

Select all the components of the equation.
X+0.20
0.825x
0.20x
x+0.825
0.0825x
x

Answers

Answer:

Step-by-step explanation:

x is the amount of the bill

tax = 8.25% of x = 0.0825x

tip = 20% of x = 0.20x

total payment = x + 0.0825x + 0.20x = 1.2825x

The total cost of the meal is given by the equation A = x + 0.2x + 0.0825x and A = 1.2825x , where x is the initial cost of the meal

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let total cost of the meal be represented as A

Now , the equation will be

Let the cost of the meal be x

Let the tip percentage be = 20 %

Now , the sales tax percentage of the meal = 8.25 %

So , the total cost of the meal A = cost of the meal + ( tip percentage x cost of the meal ) + ( sales tax percentage of the meal x cost of the meal )

Substituting the values in the equation , we get

The total cost of the meal A = x + ( 20/100 )x + ( 8.25/100 )x

On simplifying the equation , we get

The total cost of the meal A = x + 0.2x + 0.0825x

The total cost of the meal A = 1.2825x

Hence , the equation is A = 1.2825x

1. 258 square meters

2. 180 square meters

3. 286 square feet

Step-by-step explanation:

1. Find the surface area of each side:

9 * 5 + 5 * 6 + 9 * 5 + 6 * 5 + 9 * 6 + 9 * 6

45 + 30 + 45 + 30 + 54 + 54

75 + 75 + 108

150 + 108

258

2. Base: 5 * 5 = 25

Top: 5 * 5 = 25

Sides: each 5 * 6.5 = 32.5

Altogether: 32.5 * 4 = 130

130 + 25 + 25 = 180

3. Base and top: both 8 * 10 = 80, together 80 * 2 = 160

Front and back sides: both 8 * 3.5 = 28, together 28 * 2 = 56

Left and right sides: both 10 * 3.5 = 35, together 35 * 2 = 70

Altogether: 160 + 56 + 70 = 286 sq feet
