Answer:

B

Step-by-step explanation:

The equations we need are:

(5(1/8) + 4(7/8) +6 = 16) to find the total weight of pasta, sauce, and onions.

(41/8) ÷ (1/2) = ? to find how many 1/2 pound servings Mariana can make.

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

We have two types of fractions.

Proper fraction and improper fraction.

A proper fraction is a fraction whose numerator is less than the denominator.

An improper fraction is a fraction where the numerator is greater than the denominator.

Example:

1/2, 1/3 is a fraction.

3/6, 99/999 is a fraction.

1/4 is a fraction.

We have,

To find out how many 1/2-pound servings of pasta Mariana can make, we need to divide the total weight of pasta, sauce, and onions by 1/2.

Therefore, we need the equation:

(5(1/8) + 6 + 4(7/8)) ÷ (1/2) = ?

Simplifying the expression inside the parentheses, we get:

(41/8) ÷ (1/2) = ?

To divide by a fraction, we can multiply by its reciprocal. Therefore:

(41/8) ÷ (1/2) = (41/8) x (2/1) = 82/8 = 10(1/4)

So Mariana can make 10(1/4) servings of pasta.

Therefore,

The equations we need are:

(5(1/8) + 4(7/8) +6 = 16) to find the total weight of pasta, sauce, and onions.

(41/8) ÷ (1/2) = ? to find how many 1/2 pound servings Mariana can make.

Answer:

g(x) = 3 (x + (-5)) (x + (-9))

Zeros: (5 and 9)

Step-by-step explanation:

3a² -42a +135 = 3 (a² - 14a +45) = 3 (a-5) (a-9)

3 (a-5) (a-9) = 0

a = 5 or a = 9 ..... Zeros

Answer:

Let L be the number of losses. T is the total number of games, and it has the value 64. W is the number of wins.

They won 28 more than they lost, so W = L + 28.

Since W = L + 28, W = 18 + 28 = 46.

Answer:

0

Step-by-step explanation:

f(x) = y

To find f(2), it means to find the value of y when x = 2.

From the graph, when x = 2, the corresponding y-coordinate = 0.

Therefore,

f(2) = 0

Answer:

Option c.

Step-by-step explanation:

Using the normal curve to approximate a sampling distribution:

For a sample size n and a proportion n, the normal curve can be used if:

[tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]

Option a:

[tex]np = 35*0.8 = 28 > 10[/tex]

[tex]n(1-p) = 35*0.2 = 7 < 10[/tex]

So option a cannot be used.

Option b:

[tex]np = 65*0.9 = 58.5 > 10[/tex]

[tex]n(1-p) = 65*0.1 = 6.5 < 10[/tex]

So option b cannot be used.

Option c:

[tex]np = 65*0.8 = 52 > 10[/tex]

[tex]n(1-p) = 65*0.2 = 13 > 10[/tex]

So option c can be used, and is the answer

Option d:

[tex]np = 35*0.9 = 31.5 > 10[/tex]

[tex]n(1-p) = 35*0.1 = 3.5 < 10[/tex]

So option d cannot be used.

The answer is given by option c.

Answer:

3/7 times 5/4

Step-by-step explanation:

when dividing fractions, all you do is keep the first fraction, change the sign to multiplication, and flip the last fraction. In this case it would be 3/7 and 5/4

Answer:

The answer is B: 3/7 times 5/4.

Step-by-step explanation:

The process is stay, change, flip.

Stay equals keep the first fraction the same (3/7).

Change equals change the operation (division to multiplication).

Flip equals flip the second fraction (flip 4/5 to 5/4).

Answer:

23.9425 (Round if needed)

Step-by-step explanation:

This is 2 half circles so you can find the area of a circle and divide it by 2.

First circle has a diameter of 6 cm

6/2=3 cm

So, circle has radius of 3.

Area of circle= 3.14(pi) radius^2

3.14 x 3^2= 28.26

28.26/2=14.13 cm

Area of first half circle= 14.13

Repeat that process for the second circle.

3.14 x 2.5^2=19.625

19.625/2=9.8125

14.13+9.8215=23.9425

Area=23.9425

Answer:

The simple interest that said investment yielded was 3.75% per year.

Step-by-step explanation:

Given that Sarah's current account balance is $ 2,600, and she made a single lump sum amount of $ 2,000 eight years ago into the account, to calculate the equivalent simple interest rate (quoted annually) that she earned the following calculation must be performed:

(2,600 - 2,000) / 8 = X

600/8 = X

75 = X

2,000 = 100

75 = X

75 x 100 / 2,000 = X

7,500 / 2,000 = X

3.75 = X

Thus, the simple interest that said investment yielded was 3.75% per year.

Given:

A figure of a right triangle.

To find:

The value of x and value of y.

Solution:

In a right angle triangle,

[tex]\sin \theta = \dfrac{Opposite}{Hypotenuse}[/tex]

[tex]\cos \theta = \dfrac{Base}{Hypotenuse}[/tex]

In the given triangle,

[tex]\sin (60^\circ)=\dfrac{x}{6}[/tex]

[tex]\dfrac{\sqrt{3}}{2}=\dfrac{x}{6}[/tex]

[tex]\dfrac{\sqrt{3}}{2}\times 6=x[/tex]

[tex]3\sqrt{3}=x[/tex]

And,

[tex]\cos (60^\circ)=\dfrac{y}{6}[/tex]

[tex]\dfrac{1}{2}=\dfrac{y}{6}[/tex]

[tex]\dfrac{1}{2}\times 6=y[/tex]

[tex]3=y[/tex]

Therefore, the value of x is [tex]3\sqrt{3}[/tex] and the value of y is 3.
