Answer:

240g of 10% salt solution and 160g of 5% salt solution

Step-by-step explanation:

Simpler way:

Let X be the amount of 10% salt solution and Y be the amount of 5% salt solution.

Then X:Y = 3:2 as you need more 10% salt solution than 5% salt solution to create a 8% salt solution. The ratio 3:2 is given as 10 - 8 = 2 and 8-5 = 3.

If X:Y = 3:2 = 60:40, then 60% of the 400g of 8% salt solution must be the 10% solution and 40% of the 400g of 8% salt solution must be the 5% solution. Therefore, 240g of the 10% salt solution and 160g of the 5% salt solution is needed to create 400g of the 8% salt solution.

This is correct as the amount of salt in the solution is equal to (10% X 240g = 24g) + (5% of 160g = 8g). So the total amount (24+8) 32g should be equal to the amount of salt in the 400g of 8% salt solution.

8% of 400g = 32g which means our answer is correct.

More complex way:

A more complex way is to use algebra.

Let X be the amount of 10% salt solution and Y be the amount of 5% salt solution.

X + Y = 400g

and 10% of X + 5% of Y = 8% of 400

so 1/10 X + 1/20 Y = 32

2X + Y = 640 (multiply the previous equation by 20)

Now from the first line we know that X + Y = 400

So if we subtract (2X+Y) by (X+Y) we can get the value of X:

(2X+Y) - (X+Y) = 640 - 400

2X+Y - X - Y = 240

Therefore X = 240

And since X + Y = 400, Y = 160.

Answer:

Option C is the right answer.

Step-by-step explanation:

1/2 × 1/3 = 1/6

Answer:

C. 1/6

Step-by-step explanation:

it is not a whole pizza, it is half, so 1/3 of a half pizza is equal to 1/6 a whole pizza.

Answer:

y = 1/2 - 3/2

Step-by-step explanation:

All we need to do is find the y-intercept of the line using the formula for slope intercept form [ y = mx + b ].

-3 = 1/2(-3) + b

-3 = -1.5 + b

-1.5 = b

We can put all the information we know/solved for into the formula.

y = 1/2 - 1.5

Best of Luck!

Answer:

The equation of the line is y = 1/2x - 3/2

Step-by-step explanation:

Plug in point (-3, 3) with slope 1/2 into y = mx + b

-3 = 1/2(-3) + b

-3 = -3/2 + b

+3/2     +3/2

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

-3/2 = b

hence, y = 1/2x - 3/2

Answer:

$44

Step-by-step explanation:

Let the total amount of money be represented by Y

Amount spent on fresh food =

[tex] \frac{4}{7} \times y[/tex]

Remainder =

[tex]y - \frac{4}{7}y = \frac{3}{7} y[/tex]

Amount spent on frozen foods = two-thirds of remainder = $22

[tex] = \frac{2}{3} \times \frac{3}{7} y = \frac{2}{7} y[/tex]

[tex]\frac{2}{7} y = 22 \\ y = 22 \times \frac{7}{2} \\ y = 77[/tex]

The total amount for grocery shopping is $77

Therefore, Brittany spent $44 on fresh foods

[tex] = \frac{4}{7} \times 77 \\ = 4 \times 11 \\ = 44[/tex]

Answer

Because velocity and speed differ each other by direction, in a 100 m sprint race the person moves in a straight path without changing its direction where as in a 400 m race. The person moves in a lap around the race track and the direction changes as he turns according to the race track.

Answer:

I'd guess 54

Step-by-step explanation:

If the sections are all equal sized, there's an equal chance the arrow/spinner would land on them. If you divide 240 by 5, you get 48. The closest number to 48 is 54.

Answer:

I think C is the correct answer

Answer:

I dont know

Step-by-step explanation:

Answer:

Complete step-by-step answer:

Sum of 3 consecutive odd numbers is equal to 51.

Let the odd number be ‘x’. Then the next consecutive odd number becomes ‘x + 2’ and the next term becomes x + 2 + 2 = ‘x + 4’.

Now the sum of these three odd consecutive terms = x + x + 2 + x + 4 = 3x + 6.

According to the given, 3x + 6 = 51.

⟹3x = 51 – 6

⟹x =453=15.

Hence, the numbers are 15, 17 and 19.

Note: In order to solve this type of questions the key is to consider a variable to be odd and compute the sum of three consecutive odd numbers in terms of this variable. Then by solving for this variable we can determine the numbers. Any odd number added with 2 gives an odd number itself.
