Answer:

[tex]2\frac{2}{3}[/tex] cups of milk

Step-by-step explanation:

The problem is [tex]\frac{2}{3}[/tex] of a cup per milkshake times 4 milkshakes.  Keeping in mind that we can write any number over 1 without changing its value, our math problem is:

[tex]\frac{2}{3}[/tex] × [tex]\frac{4}{1}[/tex]

We multiply numerator times numerator and denominator times denominator to get [tex]\frac{8}{3}[/tex].  If we convert that improper fraction to a mixed number fraction we get [tex]2\frac{2}{3}[/tex].

The number of cups of milk would be 2 2/3 needed in the four milkshakes.

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

We have been given that martin is making four milkshakes. The recipe calls for 2/3 cup of milk.

We have to determine the number of cups of milk he needs

Let the number of cups of milk would be x in the four milkshakes.

As per the given situation, we can write the ratio would be as:

1 milkshakes : 2/3 cup of milk = 4 milkshakes : x cup of milk

⇒ 1 / (2/3) = 4/x

Reciprocal the term in the numerator,

⇒ 3/2 = 4/x

Apply the cross-multiplication operation,

⇒ 3x = 8

⇒ x = 8/3

⇒ x = 2 2/3

Thus, the number of cups of milk would be 2 2/3 in the four milkshakes.

Answer:

Step-by-step explanation:

A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).

The equation of a line is given by the expression:

(y-y1)=m(x-x1)

in the given problem the slope is m=1 and the point (x1, y1) is (5, 3), so substituting those values we have:

(y-3)=1(x-5)

simplifying:

y-3=x-5

isolating "y":

y=x-5+3

y=x-2

The complete questions is,

Which is the equation of a line that has a slope of 1 and passes through point (5, 3)? A.y = x – 2

B.y = x + 2 C.y = x + 3

As given in the question,

Margin of error = 2%

                          = 0.02

Sample proportion 'p' = 0.5

⇒ (1 - p) = 1 - 0.5

             = 0.5

Let 'n' represents the sample size

Z- value at confidence interval 90% = 1.645

Formula used

Margin of error = z-value √ [p( 1-p)/n]

Substitute the value we get,

0.02 = 1.645 √ (0.5)(0.5)/n

Squaring on both the side

0.0004 = 2.706025 ( 0.25/n)

⇒ n = ( 2.706025 × 0.25 )/ 0.0004

Based on the information, the two integers are 30 and 31.

Let the first integer be x. The second consecutive integer will be (x + 1).

So, the smaller integer = 2x

The larger integer = 3(x + 1)

Their sum = 153

Forming the equation now -

2x + 3(x + 1) = 153

Performing multiplication on Left Hand Side of the equation

2x + 3x + 3 = 153

Performing addition on Left Hand Side of the equation

5x = 153 - 3

Performing subtraction on Right Hand Side of the equation

5x = 150

x = 150/5

Performing division on Right and Side of the equation

x = 30

Smaller integer = 30

Answer:

x = 9

Step-by-step explanation:

Triangles are similar due to AAA (all angles are congruent due to shared angle and corresponding angles). Thus, the sides are proportional, and we can set up a proportion with corresponding sides:

9/(72 + 9) = (3x - 20)/(3x - 20 + 56)

9/81 = (3x - 20)/(3x + 36)

(1/9) * (3x + 36) = 3x - 20

(3x + 36)/9 = 3x - 20

3x + 36 = (3x - 20)*9

3x + 36 = 27x - 180

36 + 180 = 27x - 3x

216 = 24x

x = 9

According to the Pythagoras theorem, the exact value of tan A is 3/4 and the value of tan B is 15/8

Pythagoras Theorem

Pythagoras theorem defines that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“

Given,

Here we have the value of sin A = 3/5, cos B = 8/17 and A and B are acute angles.

And we need to find the value of tan A and tan B.

According to the Pythagoras theorem,

If the value of sin A = 3/5, then we have the value of the right angle triangle of hypotenuse and the opposite.

So, the adjacent value is calculated based on the theorem is,

=> 5² = ad² + 3²

=> 25 = ad² + 9

=> ad² = 25 - 9

=>  ad = √16

=> ad = 4

Therefore, the value of tan A is written as,

=> tan A = opposite/ adjacent

=> tan A = 3/4

Similarly, the value of tan B is calculated as,

If the value of cos B = 8/17, then we have the value of the right angle triangle of hypotenuse and the adjacent.

So, the opposite value is calculated based on the theorem is,

=> 17² = 8² + op²

=> 289 = 64 + op²

=> op² = 289 - 64

=> op = √225

=> op = 15

Therefore, the value of tan B is written as,

=> tan B = opposite/ adjacent

=> tan B = 15/8
