Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator.

Answer:

4 9/20

Step-by-step explanation:

We are subtracting since he gave them candy

Let's get the whole numbers out of the way

7 - 2 = 5

Now we subtract the fractions

1 / 4 - 4 / 5. We need to find the LCD (Lowest common denominator) of the fractions which is 20 because 4 x 5 = 20 and 5 x 4 = 20

Rewriting the denominators and numerators:

Since we multiply 4 by 5 to get 20 we'll have to do the same to the numerator (1)

1 x 5 = 5

Now we do the same to 4/5. 5 x 4 = 20 and 4 x 4 = 16.

New fractions

5/20 - 16/20 switch it 16 / 20 - 5 / 20 = 11/20  and we get the answer from subtracting the whole numbers by 11/20 (the answer we got from subtracting fractions) 5 - 11/20 = 4 9/20

Answer:

  (x, y) = (-3, -6)

Step-by-step explanation:

You want the solution to the system of equations 6 = -4x +y, -5x -y = -21 using the substitution method.

Adding 4x to the first equation gives an expression for y:

  6 +4x = y

This can be substituted into the second equation:

  -5x -(6 +4x) = 21

  -9x -6 = 21 . . . . . simplify

  -9x = 27 . . . . . . . add 6

  x = -3 . . . . . . . . . divide by -9

  6 +4(-3) = y . . . . . . . find y using the expression for y

  6 -12 = -6 = y

The solution is (x, y) = (-3, -6).

Answer: 0.7 I think

Step-by-step explanation:

The percent of error of Jin's mother's estimate is 4,9% (4,9 percent)

The Percent of error of Jin's mother's estimate can be calculated as follows ?

The first step is to convert a half gallon to ounces

1 gallon = 153,722 ounces

= [tex]\frac{1}{2}[/tex] × 153,722

= 76,861 ounces

The next step is calculate the error between Jin's mother's estimate (76,861 ounces) and the actual amount of fruit punch in the container (72 ounces)

The error = 76,861 - 72

= 4,861

Third step is to round the calculated the percent error to the nearest tenth.

4,861 ÷ 100 = 4,861%

The final step is to round it to the nearest tenth by round the second digit behind the coma which has value more than 5 to the higher number of the first digit behind the coma.

4,861% = 4,9%

Hence, the percent error of Jin's mother's estimate is 4,9% (4,9 percent)

Answer:

  9641 + 9641 = 19282

Step-by-step explanation:

You want to assign a different digit to each of the letters H, A, L, T, E, R such that ...

  HALT + HALT = THERE

The T in the most significant digit of the sum must be T = 1, because a carry from the sum of two digits cannot exceed 1. That means E = 2. In order for H+H = TH, we must have ...

  H + H + 1 = 10 + H

  H = 9

In order for there to be a carry into the 4th column (from the right), the value of A must be 5 more than the value of T:

  A = 6

Since E in the third sum digit is even, there can be no carry from the sum L +L = R. This leaves R an even digit not 0, 2, or 6. It cannot be 4, because that would require L=2, but we already have E=2. This leaves R = 8 and L = 4.

The sum is ...

  HALT +HALT = THERE   ⇒   9641 +9641 = 19282

The value of THERE is 19282.

The descending numeric order of the laps was completed as 59, 58, 45, 0.875,0.833

Descending order is defined as when numbers (or other items) are arranged from the largest numbers to the least numbers, it is said to be in descending order.

Sara finished 45 laps, Jamie completed 58, Keenan completed 59, Maya completed 0.833, and Trey completed 0.875.

We have the given numbers as:

45, 58, 59, 0.833, 0.875

we have to determine the descending order of given numbers

Here the largest numbers to the least numbers, it is said to be in descending order.

⇒ 59  > 58  > 45  > 0.875 > 0.833

Hence, the descending numeric order of the laps completed:

Keenan completed 59 laps

Jamie completed 58 laps

Sara completed 45 laps

Trey completed 0.875 laps

Maya completed 0.833 laps

Answer:

Step-by-step explanation:

First you need to add, and then simplify

Answer: x=230 and y=75

Step-by-step explanation: A triangle is worth 360 degrees, which means when you add up all the angles it equals 360 degrees. So

Second patio:

(x-10),60+80 = 360

x-10+140 =360-140

x-10=220+10

x=230

First patio:

(x+10)+(y+5)+40 = 360

x+y+55=360

x+y=360-55

x+y=305- x(230) =75

y=75

Answer: x = 50, y = 75

The sum of angles of a triangle is equal to 180°

according to the question, (x+10) + (y+5) + 40 = 180 -- eq(1)

(x-10) + 60 + 80 = 180 -- eq(2)

(x - 10) + 140 = 180

x - 10 +140 = 180

x + 130 = 180 , x = 180 - 130

x = 50

put x value in eq(1)

50+10 + (y+5) + 40 = 180

60+(y+5)+40 = 180

y+5 +100 = 180

y + 105 = 180

y = 180 - 105

y = 75

So, x = 50 and y = 75.

Answer:

Step-by-step explanation:Answer:

Part a) You could build 5 copies of the flower pattern  

Part b) You would have 40 red trapezoids left over

Step-by-step explanation:

The complete question in the attached figure

Part a)

Let

x -----> the number of yellow hexagons

y ----> the number of red trapezoids

z ----> the number of green triangles

we know that

The flower pattern has the following ratios

Find out how many copies of this flower pattern could you build if you had 30 yellow hexagons,50 red trapezoids, and 60 green triangles

1) For x=30

Divide 30 by 6 (remember that in one pattern there are 6 yellow hexagons)

Verify the quantity of y needed and the quantity of z needed

Find the value of y

10 < 50 ----> is ok

Find the value of z

45<60 --->is ok

2) For y=50

Divide 50 by 2 (remember that in one pattern there are 2 red trapezoids)

Verify the quantity of x needed and the quantity of z needed

Find the value of x

150 > 30 ----> is not ok

3) For z=60

Divide 60 by 9 (remember that in one pattern there are 9 green triangles)

60/9=6.7 copies

Round down

6 copies -----> 6(9)=54 green triangles

Verify the quantity of x needed and the quantity of y needed

Find the value of x

36> 30 --->is not ok

therefore

You could build 5 copies of the flower pattern

Part b)

we know that

x:y:z=6:2:9

If you build 5 copies

1) You would use 5*6=30 yellow hexagons and you would have 0 hexagons left over

2) You would use 5*2=10 red trapezoids and you would have (50-10=40) trapezoids left over

3) You would use 5*9=45 green triangles and you would have (60-45=15) triangles left over

therefore

You would have 40 red trapezoids left over

Answer:

Step-by-step explanation:

knoweth thay multiplication table.

what are the multiples of 9 ?

1×9 = 9

2×9 = 18

3×9 = 27

4×9 = 36

5×9 = 45

6×9 = 54

7×9 = 63

8×9 = 72

9×9 = 81

10×9 = 90

because multiples of 10 follow the same structure, we just add 0s.

so, the multiples of 90 are the same numbers as above, they just have a 0 at the end.

and if we also multiply the first numbers (1 ..10) by 10, the results get a second additional 0 at the end.

so, when we look at

3600

5400

6400

7200

we actually look at

36

54

64

72

36 = 4×9

so, 3600 has to be divided by 40 to result in 90.

but it is divided by 50. so, no.

54 = 6×9

so, 5400 has to be divided by 60 to result in 90.

and it is. so, yes ! 5400 ÷ 60 = 90

64 is no factor of 9 at all. so, no.

72 is 8×9

so, 7200 has to be divided by 80 to result in 90.

but it is divided by 90. so, no.
