Answer:

If a spinach pie is cut into 10 equal pieces, the fraction form of it is 1/10 and the decimal form is 0.1

Step-by-step explanation:

10 pieces

10/10 total

1 slice: 1/10

1 = whole pie

split into 10 equal peices =

0.1

Given:

y is proportional to x.

y=10 and x=8.

To find:

The constant of proportionality and the equation for the proportional relationship.

Solution:

y is proportional to x.

[tex]y\propto x[/tex]

[tex]y=kx[/tex]               ...(i)

Where, k is the constant of proportionality.

Putting y=10 and x=8, we get

[tex]10=k(8)[/tex]

[tex]\dfrac{10}{8}=k[/tex]

[tex]\dfrac{5}{4}=k[/tex]

Putting [tex]k=\dfrac{5}{4}[/tex] in (i), we get

[tex]y=\dfrac{5}{4}x[/tex]

Therefore, the contestant of proportionality is [tex]k=\dfrac{5}{4}[/tex] and the equation for the proportional relationship is  [tex]y=\dfrac{5}{4}x[/tex].

Given:

Jake bought 3 drawing pens for $8.07.

Each pen costs the same amount.

To find:

How much did he spend for one pen?

Solution:

Let x be the cost of each pen. Then

Cost of three pens = 3x

Jake bought 3 drawing pens for $8.07.

[tex]3x=8.07[/tex]

Divide both sides by 3.

[tex]x=\dfrac{8.07}{3}[/tex]

[tex]x=2.69[/tex]

Therefore, he spend $2.69 for one pen.

Answer:

8 hours

Step-by-step explanation:

let number of hours it takes to finish the cup be t,

we know that we have 80 cups, and we know we can finish 10 cups per hour so,

10t = 80 which is 10 times t = 80

Solve for t,

10t/10 = 80/10

t = 8

Answer: x  =  1  ,  y  =  0

Answer:

X=20

Step-by-step explanation:

360/18=20

Answer:

x=20

Step-by-step explanation:

18x=360

divide both sides by 18x

[tex]\frac{18x}{18}[/tex]=[tex]\frac{360}{18}[/tex]

simplify

x=20

hope this helps :) have a nice day !!

Answer:

£1560

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year,

then, solving our equation

I = 1200 × 0.06 × 5 = 360

I = £ 360.00

The simple interest accumulated

on a principal of £ 1,200.00

at a rate of 6% per year

for 5 years is £ 360.00.

Answer:

90<150

Step-by-step explanation:

add 80 and 10 put it in front of 150

Answer: The family's weekly income is $1500

-------------------------------------------

Work Shown:

x = weekly income (in dollars)

16% of x = amount spent on food per week

16% of x = 240

(16/100)*x = 240

0.16*x = 240

0.16*x/0.16 = 240/0.16

x = 1500

Pls Mark as brainliest

Answer:

1500

Step-by-step explanation:

16% of x = amount spent on food per week

16% of x = 240

(16/100)*x = 240

0.16*x = 240

0.16*x/0.16 = 240/0.16

x = 1500

Answer:

5 1/2 or 5.5

Step-by-step explanation:

=8 1/2+2 1/6-5 2/12

=17/2+ 2 1/6-5 2/12

=17/2+13/6-5 2/12

=32/3- 5 2/12

=32/3-31/6

=11/2

=5 1/2

Answer:110

Step-by-step explanation:

Answer:

it should be 41/100. Percentage means the denominator in 100.

41/100. Percentage means the denominator in 100.

is the correct answer

Answer:

golden corral equation y=1.5x+15

western sizzlin equation y=2.5x+13

yes they are linear because if you were to graph them they would have a straight line and they would go upwards because the slope is positive

For which one you would pick would depend on how much you drink. If you drink a lot you should probably go to golden corral but if you dont drink that much then western sizzlin is probably the best choice.

Answer:0.75757575757

Answer:

Fraction Form

25/33

Decimal Form

0.75

Step-by-step explanation:

First, convert the mixed fraction into an improper fraction, so it would look like:

-5/3 / (-11/5)

Next, divide. Remember, when multiplying fractions all you do is flip the one in parantheses and make both of them positive, so it would look like:

5/3 x 5/11

Finally, multiply so you do the two top numbers which is 5 x 5= 25 and the two bottom numbers so 11 x 3 is 33. Then your final answer is 25/33

Answer:

x = 40

Step-by-step explanation:

∠D = ∠ADB + ∠BDC

    = 30 + 40

    = 70°

In ΔBDC,

BD = CD

∠DBC = ∠DCB  {angles opposite to equal sides are equal}

∠DBC + ∠DCB + ∠BDC = 180  {Angle sum property}

2∠DCB + 40 = 180

             2∠DCB = 180 -40

             2∠DCB = 140

    ∠DCB= 140/2

∠DCB = 70°

In ΔADC,

x + ∠D + ∠C = 180

x + 70 + 70 = 180

x + 140 = 180

x = 180 - 140

x = 40°

Answer:

$94.12

Step-by-step explanation:

($94.11 + $52.75) + (-$25.20 + -$22.04 + -$8.50) =

($146. 86) - (-$55.74) =

$94.12

$94.12 is the account balance at the end of the month.

$10.50

Explanation:

Let x be the cost of the individual books. Then 24.81=3x−6.69

3x= 24.81+ 6.69 =31.50

x=31.50/3=10.50

Step-by-step explanation:

Answer:

The expression of how Susan solved 99 × 47 is;

99 × 47 = 100 × 47 - 47

The evaluation of the expression is;

99 × 47 = 4653

Step-by-step explanation:

The question relates to the simplification of the multiplication of two numbers by the use of a combination multiplication of one of the numbers, 'x', with the nearest 10s or 100s of the other number, 'y', followed by the subtraction or addition operation of the product between the number 'x' and the difference between the specified 10s or 100s and 'y';

The given information on how Susan solved the equation 99 × 47 can be presented as follows;

99 × 47 = (100 - 1) × 47 = 100 × 47 - 47

The expression of how Susan solved 99 × 47 is therefore presented as follows;

99 × 47 = 100 × 47 - 47

The evaluation of the expression is therefore given as follows;

100 × 47 - 47 = 4700 - 47 = 4653.
