<span>We can either calculate each fraction and compare the results, or bring all of the fractions to a common denominator by finding the smallest common multiple for the fractions' denominators (3, 10, 8, 2), which is 3 * 2^3 * 5 = 120. Thus we must amplify each fraction so that its denominator becomes 120. 2/3 becomes 40/120, 5/10 becomes 60/120, 7/8 becomes 105/120 and 1/2 becomes 60/120. We can clearly see now that the largest of these fraction is the third (105/120). So the answer is C. Sarah.</span>

A radio station is going to construct a 5-foot tower on top of a building. the tower will be supported by three cables, each att

KonstantinChe [14]

You need to use Pythagoras’ Theorem.
A² + B² = c² and c is the hypotenuse of the right angled triangle.

The height of the tower (5 feet) is A and the distance from the end of the cable and the base of the tower (12 feet) is B. The length of ONE cable is c. So:

A² + B² = c²
5² + 12² = c²
25 + 144 = c²
169 = c²
13 = c. This is the length of one cable.

3 x 13 = 39 therefore the total length of the cables is 39 feet.

In a list of households, own homes and do not own homes. Four households are randomly selected from these households. Find the p

labwork [276]

Complete Question

In a list of 15 households, 9 own homes and 6 do not own homes. Four households

are randomly selected from these 15 households. Find the probability that the

number of households in the sample which own homes is exactly 3

Answer:

Step-by-step explanation:

From the question we are told that

The number of household is n = 15

The number of household that own homes is k = 9

The number of household that do not own homes is u = 6

The number of households randomly selected is q = 4

Generally the number of ways of selecting 3 household from the total number of 9 households that own homes is mathematically represented as

$A = ^{k} C_ 3$

Here C stands for combination hence we would be making use of the combination feature in our calculator

=> $A = ^{9} C_ 3$

=> $A =84$

Generally the number of ways of selecting 1 household from the total number of 6 households that do not own homes is mathematically represented as

$B = ^{u}C_1$

=> $B = ^{6}C_1$

=> $B = 6$

Generally the number of ways of selecting 4 household from the total number of 15 households on the list is mathematically represented as

$D = ^{n}C_4$

=> $D = ^{15}C_4$

=> $D = 1365$

Generally the probability that the number of households in the sample which own homes is exactly 3 is mathematically represented as

$P( X = 3) = \frac{A * B}{D}$

=> $P( X = 3) = \frac{85 * 6}{1365}$

X is here represent the number of household in the selected sample that own homes

=> $P( X = 3) = 0.3736$

Bryan and Jadyn had barbeque potato chips and soda at a football party. Bryan ate 4 oz of chips and drank 1 cup of soda for a to

Inga [223]

Answer:

1 oz of chips has 140 mg of sodium, and 1 cup of soda has 40 mg of sodium.

Step-by-step explanation:

This question is solved by a system of equations.

I am going to say that:

x is the amount of sodium in 1oz of chips.

y is the amount of sodium in 1 cup of soda.

Bryan ate 4 oz of chips and drank 1 cup of soda for a total of 600mg of sodium.

This means that $4x + y = 600$ , also $y = 600 - 4x$

Jadyn ate 1 oz of chips and drank 4 cups of soda for a total of 300mg of sodium.

This means that:

$x + 4y = 300$

From the first equation, we have that $y = 600 - 4x$ . So

$x + 4(600 - 4x) = 300$

$x + 2400 - 16x = 300$

$15x = 2100$

$x = \frac{2100}{15}$

$x = 140$

$y = 600 - 4x = 600 - 4*140 = 40$

1 oz of chips has 140 mg of sodium, and 1 cup of soda has 40 mg of sodium.
