Answers

Answer 1

Answer: 1 part almond
2 parts walnut
3 parts raisins
6 parts in all.

almond = 12 per pound
walnuts = 9 per pound
raisins = 5 per pound

1/6 * 12 = 2
2/6 * 9 = 3
3/6 * 5 = 2.5
total 7.5

15/7.5 = 2

almond: 2 * 2 = 4 ⇒ 4/12 = 1/3 pounds of almonds
walnut: 3 * 2 = 6 ⇒ 6/9 = 2/3 pounds of walnuts
raisins: 2.5 * 2 = 5 ⇒ 5/5 = 1 pound of raisins

1/3 + 2/3 + 1 ⇒ 1/3 + 2/3 + (1 *3/3) = 1/3 + 2/3 + 3/3 = 6/3 = 2 pounds of trail mix.

If 0 < x < 1 , which of the following lists the numbers in increasing order ??(a) √x , x , x²
(b) x² , x , √x
(c) x² , √x , x

Answers

Answer:

(b) x² , x , √x

Step-by-step explanation:

Since, when x is a real number,

Such that 0 < x < 1

Then with increasing the exponent of x the value of x decreases,

That is, x with highest exponent is lowest,

Since,

$2 > 1 > (1)/(2)$

Thus, by the above statement,

$x^2 < x < x^(1)/(2)$

Hence, the numbers in increasing order is,

x² , x , √x

Where, 0 < x < 1

Option (b) is correct.

answer B

$x = (1)/(4)$
$\sqrt{ (1)/(4) }= (1)/(2)$
$((1)/(4))^2 = (1)/(16)$

$(1)/(16)\ \textless \ (1)/(4)\ \textless \ (1)/(2)$

The high school is hosting an event for seniors but will also allow some juniors to attend. The principal approved the event for 200 students and decided the number of juniors should be 25% of the number of seniors. How many juniors will be allowed to attend?

Answers

Using percentage, the numbers of juniors will allowed to attend an event is 50.

What is percentage?

Percentage is "fraction or ratio, in which value of whole is 100".

According to the question,

The principal approved the event for 200 students. Number of juniors will be 25% of number of seniors.

Suppose 100% of student is 200 and then 25% of student will be

100% = 200

25% = x

100x = (200) (25) [cross multiplication]

x = 50.

Hence, the principal allowed number of student to attend an event is 50.

the perimeter of a triangle is 8x+3y. The length of two sides of the triangle are 4x+y and 2x-3y. Find the measure of the third side of the triangle.

Answers

Perimeter = Sum of three sides.

Let the third side be = t

Perimeter = 8x + 3y

8x + 3y = (4x + y) + (2x - 3y) + t

8x + 3y = 4x + y + 2x - 3y + t

8x + 3y = 4x +2x + y - 3y + t

8x + 3y = 6x - 2y + t

8x - 6x + 3y + 2y = t

2x + 5y = t.

Therefore third side = 2x + 5y
