Answer:

142.9

Step-by-step explanation:

litres of milk

30/100=x/125

10x=375

x=37.5

14% of milk

14/100=x/125+y

1750+14y=100x

1750=100x–14y

1750=100(37.5)–14y

1750=3750–14y

y=2000/14=142.9

Answer:

175

Step-by-step explanation:

To find a proportion, you need to put both parts over the total.  You would put the part of silver (14) over the total (80) and the part you are trying to find (X) over the total number of students (1,000). Then you cross multiply 14 x 1,000 and divide by 80 giving you 175 silver cars.

Answer:

El total de líquido utilizado es [tex]\frac{5}{6} de litro[/tex]. Se echa [tex]\frac{1}{6}[/tex] de litro más de leche que de jugo

Step-by-step explanation:

Para saber la cantidad total de líquido, basta con sumar las cantidades de leche y de jugo de naranja. Vamos a asumir que usa 1/3 de litro de jugo de naranja.

En este caso el total de líquido es 1/2 litro + 1/3 litro. Dado que estas fracciones tienen distinta denominador, debemos sumarlas de la siguiente manera

[tex] \frac{1}{2}+\frac{1}{3} = \frac{1\cdot 3 + 2\cdot 1}{2\cdot 3} = \frac{5}{6}[/tex]

Para calcular la cantidad extra de leche de más que la cantidad de jugo, restamos estos números. Es decir

[tex] \frac{1}{2}-\frac{1}{3} = \frac{1\cdot 3 - 2\cdot 1 }{2\cdot 3} = \frac{1}{6}[/tex]

Es decir, que echamos [tex]\frac{1}{6}[/tex] de litro más de leche que de jugo.

Solve for x.

41. (x + a)/b + b = a

1. Subtract b.

(x + a)/b = a - b

2. Multiply by b.

x + a = ab - b^2

3. Subtract a.

x = ab - b^2 -a

42. bx + a = dx + c

1. Subtract a.

bx = dx + c - a

2. Subtract dx.

bx - dx = c - a

3. Factor x out.

x(b -d) = c - a

4. Divide by (b-d).

x = (c-a)/(b-d)

43. cx - b = ax + d

1. Add b.

cx = ax + d + b

2. Subtract ax.

cx - ax = d + b

3. Factor x out.

x(c -a) = d + b

4. Divide by (c-a).

x = (d +b)/c-a).

44. a(x -3) + 8 = b(x - 1)

1. Distribute everything.

ax - 3x + 8 = bx - b

2. Subtract 8.

ax - 3a = bx - b -8

3. Subtract bx.

ax - bx - 3a = -b - 8

4. Factor x out.

x ( a - b) - 3a = -b - 8

5. Add 3a.

x ( a - b) = -b - 8 + 3a

6. Divide by (a-b).

x =  (-b - 8 + 3a) / (a - b)

45. c ( x + 2) - 5 = b ( x -3)

1. Distribute everything.

cx + 2c -5 = bx - 3b

2. Add 5.

cx + 2c = bx - 3b + 5

3. Subtract bx.

cx - bx + 2c = -3b + 5

4. Factor x out.

x ( c - b ) + 2c = -3b + 5

5. Subtract 2c.

x ( c - b) = -3b + 5 - 2c

6. Divide by ( c - b).

x = (-3b + 5 - 2c)/(c-b)

46. a (3tx - 2b) = c (dx -2)

1. Distribute everything

3txa - 2ba = cdx - 2c

2. Subtract cdx.

3txa - cdx - 2ba = -2c

3. Add 2ba.

3txa - cdx = 2ba - 2c

4. Factor x out.

x ( 3ta - cd) = 2ba - 2c

5. Divide by (3ta - cd).

x = (2ba - 2c)/(3ta - cd)

47. b ( 5px - 3c) = a (qx -4)

1. Distribute everything.

5bpx - 3bc = apx - 4a

2. Subtract apx.

5bpx - apx - 3bc = -4a

3. Add 3bc.

5bpx - apx = -4a + 3bc

4. Factor x out.

x ( 5bp - ap ) = -4a + 3bc

5. Divide by (5bp - ap).

x = (-4a + 3bc)/(5bp - ap)

48. [a/b(2x - 12)]= c/d

1. Multiply b first.

a ( 2x - 12) = c/d

2. Multiply by d.

ad(2x - 12) = cb

3. Distribute ad.

2adx - 12ad = cb

4. Add 12ad.

2adx = cb + 12ad

5. Divide by 2 ad.

x = (cb + 12ad)/2ad

Answer:

(2x-5)(3x-2)

Step-by-step explanation:

1)When factoring quadratic equations in for ax²+bx+c you need to separate the b term in a way that the two addends you separate it by should equal a•c. Just do trial and error. In this case you should get -4 and -15. Your separated equation should be:

6x²-4x-15x+10

2)now factor out a common factor from the first two terms and one from the last two terms you should have:

2x(3x-2)-5(3x-2)

3)finally rewrite this equation into two separate factors and you have your answer.

Answer:

3/25

Step-by-step explanation:

3 red marbles, 4 green marbles, and 3 blue marbles = 10 marbles

P(green) = number of green / total = 4/10 = 2/5

We replace it

3 red marbles, 4 green marbles, and 3 blue marbles = 10 marbles

P(red) = number of red / total = 3/10

P(green, replace,red) =2/5*3/10 = 3/25

Answer: 2.26 * 10^4

Step-by-step explanation:

This is overdetermined.  Without looking at the ratio (except for the order of the sides) the actute angles in a right triangle are complementary so the answer must be:

Answer: A=35°, C=90°, B=55°

We can do it the way they like.

7+18+11 =36

so to get 180 degrees we need to scale the ratio elements by a factor of 5.

7:18:11=35:90:55

A is the smallest.  We see C is indeed a right angle and B is complementary to A.

Complete question:

Jason has two bags with 6 tiles each. The tiles in each bag are shown below:

1 2 3 4 5 6

Without looking, Jason draws a tile from the first bag and then a tile from the second bag. What is the probability of Jason drawing the tile numbered 2 from the first bag and the tile numbered three from the second bag?

Answer: 1/36

Step-by-step explanation:

Number of tiles in each bag = 6

Probability of drawing tile numbered 2 from the first bag and the tile numbered 3 from the second

Probability of drawing number 2 from first bag :

P(numbered 2) = (required outcome / possible outcome)

P(numbered 2) = 1/6

Probability of drawing number 2 from first bag :

P(numbered 3) = 1/6

Since they are independent events :

P(drawing 2 from bag one and 3 from bag 2) :

1/6 × 1/6 = 1/36

Answer:

40 m

Step-by-step explanation:

First we have to find the width. the width is 3 less than the length, which is 8... so the width is 5. Area is found by multiplyign length times width to get 40 m.

If the width of the deck is 3 m less that the length. The length is 8m. then the area to be waterproofed is 40 m²

A rectangle is a quadrilateral with four right angles

The area of Rectangle is length times of width.

Given that Ms. Luna is waterproofing the top of a rectangular wood deck.

The width of the deck is 3 m less that the length.

Width=Length-3

Length=8

Area of rectangle=Length×Width

=Length×(Length-3)

=8×(8-3)

=8×5

=40 m²

Hence, If the width of the deck is 3 m less that the length. The length is 8m. then the area to be waterproofed is 40 m²

Answer:

Yup he can make 7 rice balls

Step-by-step explanation:

If he has 700 grams of rice and he only needs 100 grams welp that's 700/100

first you can take the zeros off so it turns into 7/1 and anything devided by it's self is itsself

So 7/1 is 7

Justin can make 7 rice balls if he has 700 grams of rice because he can make 1 rice ball using 100 grams.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We have:

Justin's rice ball recipe uses 100 grams of rice to make 1 rice ball.

The ratio of the quantity of the rice to rice ball:

100:1

Multiply the above ratio by 7

700:7

Thus, Justin can make 7 rice balls if he has 700 grams of rice because he can make 1 rice ball using 100 grams.
