Given :

Ellen sells wedges of cheese at the local farmers' market. To make the wedges, she cuts a big 5-pound block of cheese into 16 pieces.

To Find :

How much does each wedge of cheese weigh.

Solution :

Let , weight of each wedge of cheese is x.

16 pieces of wedge of cheese weight 5 pounds .

So,

[tex]16x=5\\\\x=\dfrac{5}{16}\\\\x=0.3125\ pounds[/tex]

Therefore, weigh of cheese is 0.3125 pounds.

Hence, this is the required solution.

Answer:

1. [tex]\frac{10}{21}[/tex]

2. [tex]\frac{405}{49} = 8\frac{13}{49}[/tex]

Step-by-step explanation:

first one:

[tex]p^{2} q[/tex] = [tex](\frac{1}{3})^{2}[/tex] × [tex]4\frac{2}{7}[/tex] = [tex]\frac{1}{9}[/tex] × [tex]\frac{30}{7}[/tex] = [tex]\frac{1}{3}[/tex] × [tex]\frac{10}{7}[/tex] = [tex]\frac{10}{21}[/tex]

second one:

[tex]t^{2}[/tex]/[tex]s[/tex] = [tex](1\frac{2}{7})^{2}[/tex] / [tex]\frac{1}{5}[/tex] = [tex](\frac{9}{7})^{2}[/tex] × [tex]5[/tex] = [tex]\frac{81}{49}[/tex] × [tex]5[/tex] = [tex]\frac{405}{49}[/tex] = [tex]8\frac{13}{49}[/tex]

The mistake lies in step -(66/5)/(22/5) → -(66/5)(22/5) where he didn't take the reciprocal of the divisor while dividing the two fractions.

The step would have been like this:

-(66/5)/(22/5) = -(66/5)(5/22) = -(3).

A fraction is a portion of a whole or, more broadly, any number of equal pieces.

It is written in the form p/q, read as "p by q", where p is called the numerator and q is called the denominator, and the fraction p/q represents p number of equal parts from q number of equal parts.

Fractions are of two types:

Fractions are divided by multiplying the dividend by the reciprocal of the divisor

Suppose we are asked to divide a fraction a/b by x/y.

This is written as (a/b) ÷ (x/y) or (a/b)/(x/y), and calculated as:

(a/b)*(y/x).

In the question, we are informed that last night, the temperature fell from 0°F to Negative 13 and one-fifth °F in 4 and two-fifths hours. Alan calculated the average temperature change per hour.

He followed the following steps:

-(13 1/5)/(4 2/5)

= -(66/5)/(22/5)

= -(66/5)(22/5)

= -(1452/25).

The mistake lies in step -(66/5)/(22/5) → -(66/5)(22/5) where he didn't take the reciprocal of the divisor while dividing the two fractions.

The step would have been like this:

-(66/5)/(22/5) = -(66/5)(5/22) = -(3).

Answer:

n = -5

Step-by-step explanation:

-2(-7n-8)=-39+3n

Distribute

14n +16 = -39 +3n

Subtract 3n from each side

14n -3n +16 = -39 +3n -3n

11n +16 = -39

Subtract 16 from each side

11n +16 -16 = -39 -16

11n = -55

divide by 11

11n /11 = -55/11

n = -5

Answer:

See below

Step-by-step explanation:

Short solution given below

Properties used in solution:

13.................................................

∠1 = ∠4 = ∠5 = ∠8 = 130°

∠2 = ∠3 = ∠6 = ∠7 = 180° -130° = 50°

14.................................................

2x + 90° + x = 180° ⇒ 3x = 90° ⇒ x = 30°

2y = x ⇒ 2y = 30° ⇒ y = 15°

z + 2y = 180° ⇒ z + 30° = 180° ⇒ z = 150°

15.................................................

5x - 20° = 3x ⇒ 2x = 20° ⇒ x = 10°

5x - 20° + 2y + 4y = 180° ⇒ 5*10° - 20° + 6y = 180° ⇒ 30° + 6y = 180° ⇒ y =25°

From the question the two angles that's

[tex]\angle[/tex] ZXY and [tex]\angle[/tex] WXZ are complementary since they lie on a right angle

Complementary angles are angles that add up to 90°

Let m [tex]\angle[/tex] WXZ be x

To find m [tex]\angle[/tex] WXZ add up the two angles and equate them to 180° to find the angle

So we have

[tex]\angle[/tex] WXZ + [tex]\angle[/tex] ZXY = 90

x + 26 = 90

x = 90 - 26
