She need 1/12 cup of oil. A fraction is a portion of a whole or, more broadly, any number of equal parts. In everyday English, a fraction describes the number of parts of a specific size, such as one-half, eight-fifths, or three-quarters.

To find how much need to obtain 1/3 of cup

we need to subtract what we have from what we need.

so , we have 1/4 and need 1/3

 = 1/3 - 1/4

 = [tex]\frac{1 * 4}{3 * 4} - \frac{1 * 3}{4 * 3}[/tex]

 = 1/12

Answer:

a=7, b=3

Step-by-step explanation:

Subtracting, we get the area of QRXY is 63 cm².

Using the area formula of a rectangle, we get 9a=63, and thus a=7.

Using the area formula again on triangle PXYS, 7b=21, and thus b=3.

The value of side 'a' is 7cm and side b is 3 cm.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

It is given that the area of PQRS is 84 square cm and the area of PSYX is 21 square cm.

The area of QRXY is calculated as,

Area QRXY = 84 - 21

Area QRXY = 63 square cm

The side a will be calculated as,

a x 9 = 63

a = 63 / 9

a = 7 cm

The side of b will be,
b x 7 = 21

b = 21 / 7

b = 3 cm

Therefore, the value of side 'a' is 7cm and side b is 3 cm.

Answer

a) Angle L = 36.9°

Angle N = 53.1°

b) For the relationship between them, we can see that

Angle L + Angle N = 36.9° + 53.1° = 90°

Hence, they both sum up to give 90° and are thus complementary angles.

Explanation

In a right-angle triangle, the side opposite the right angle is the Hypotenuse, the side opposite the given angle that is non-right angle is the Opposite and the remaining side is the Adjacent.

For this question, we first use Angle L as the non-right-angle angle

Hypotenuse = LN = 5

Opposite = NM = ?

Adjacent = LM = 4

Angle = L

Trignometric ratios allow us to interprete CAH as

Cos L = (Adj/Hyp)

Cos L = (4/5)

Cos L = 0.8

L = Cos⁻¹ (0.8)

L = 36.9°

Now, using Angle N as the non-right-angle angle,

Hypotenuse = LN = 5

Opposite = LM = 4

Adjacent = NM = ?

Angle = N

Trignometric ratios allow us to interprete SOH as

Sin N = (Opp/Hyp)

Sin N = (4/5)

Sin N = 0.8

N = Sin⁻¹ (0.8)

N = 53.1°

b) For the relationship between them, we can see that

Angle L + Angle N = 36.9° + 53.1° = 90°

Hence, they both sum up to give 90° and are thus complementary angles.

The width of a standard railroad track is 4 Feet, 8 inches

A Locomotive has a length of 76 feet

A model boxcar has a length of 4.2 inches

width be of an N scale train track, in inches

4 feet 8 inches = 4 * 12 inches + 8 inches = 56 inches

1 foot = 160 feet is same as 12 inches = 12 * 160 inches = 1920 inches

12 inches = 1920 inches

? = 56 inches

? = 56 * 12 / 1920

? = 0.35 inches

A Locomotive has a length of 76 feet

76 feet = 912 inches

12 inches = 1920 inches

? = 912 inches

? = 5.7 inches

A model boxcar has a length of 4.2 inches

12 inches = 1920 inches

4.2 inches = ?

? = 4.2 * 1920 / 12

? = 672 inches

Answer: I think it is -5, but im not very sure srry

Step-by-step explanation:

The x-components of the vertices are all that need to be taken into consideration for reflection along a vertical axis (x = -1).

The x-coordinates and y-coordinates move when a point is reflected across the line y = x. The line y = x reflects the point (x, y), and the reflection is (y, x).

The new value of x for any point (x, y) would be the angle 'd' with respect to the reflection axis (x -(-1)), then inverted for reflection around the reflection axis x = -1. x’ = -1 -d… where x = -1 -(x + 1) = -x -2 and d = (x - (-1)) = (x + 1)

For instance, if a = (1, 3), a' = (-1, -2, 3) = (-3, 3).

If you have a triangle with some vertices on one side and some on the other, straddling the axis, this reflection will still hold true for vertices on either side of the reflection axis.

First, if we draw the lines of the equations x-y = -3 and 3x+2y = 0, we get the following:

the red line represents the first equation and the blue line represents the second equation. But since we are working with inequalities, the intersection between these two inequalities will be the intersection of the semiplanes that they form.

To check the region that will be the intersection, we can check two opposite points and see if both inequalities are true. In this case, if we take the points (-2,-2) and (2,2), we get the following:

notice that the second inequality is not true. Now, with the point (2,2), we get:

which are true, therefore, the region that represents both inequalities is the following:

So, d = 20 inches

We will find the radius of the circle (r)

The diameter is two times the radius

Or, we can say, the radius is half of the diameter

Using proportions, it is found that Micah caught up to Taylor at 11:06 AM.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using relations in the context of the problem.

For this problem, the relation between velocity, distance and time is used, that is, velocity equals distance divided by time, hence:

v = d/t.

Then the distance is:

d = vt.

For Taylor, his trail is divided in these following intervals:

For Micah, the time that he took to complete the trail is:

t = d/v = 8/7 = 1.14 hours.

Hence he completed his trial around 11:40 AM, as he left at 10:30 A.M.

He caught up to Taylor during the first interval of his trip, when the motion functions are as follows:

QUESTION:

you want to buy some beans a 6 oz package cost $2.10 a 14 oz package cost $5.04 a 20 oz package cost $6.60​. Which package is the best to buy?

ANSWER

We will first find the unit price.

6 0z = $2.10

1 oz = $2.10/6 = $0.35

a 14 oz package that cost $5.04

14 0z = $5.04

1 oz = $5.04 / 10 = $0.504

a 20 oz package that cost $6.60

20 oz = $6.60

1 oz = $6.60 / 2 =$3.30

Comparing the three prices, the 6 oz package that cost $2.30 has the lowest price. This implies that it is the best to buy.

Now, we graph.

Where h is the hypothenuse.

To find the hypothenuse of the right triangle formed, we use the distance formula and both points.

Replacing the coordinates, we have

Therefore, the hypotenuse is 7.83 units long, approximately.

At last, the area of the triangle is found with the formula

Where b is the base and h is the height of the triangle. b = 3.5, h = 7.

Replacing these values, we have

Therefore, the area of the triangle is 12.25 square units.

The greatest common factor and least common multiple are the best used to simplify a fraction.

Suppose we wanted to add the fractions:

10/12 and 20/15.

Now, consider the fraction:

10/12

We can eliminate that component from both the numerator and the denominator and simplify the fraction if we can identify the greatest common factor between 10 and 12.

So,

The factors of 10 are 1, 2, 5, 10.

The factors of 12 are 1, 2, 3, 4, 6, 12.

Therefore, GCF of 10 and 12 is 2.

Hence,

10/12 = ( 10 ÷ 2 ) / ( 12 ÷ 2 ) = 5/6

Similarly,

For 20/15,

The factors of 20 are 1, 2, 4, 5, 10, 20.

The factors of 15 are 1, 3, 5, 15.

The greatest common factor is 5.

So,

20/15 = ( 20 ÷ 5 ) / ( 15 ÷ 5 ) = 4/3

Now, when we add the fractions:

10/12 + 20/15 = 5/6 + 4/3

Now, as the fractions are already simplified.

By using the least common multiple.

10/12 + 20/15 = 5/6 + ( 4/3 ) × ( 2/2 )

10/12 + 20/15 = 5/6 + 8/6

10/12 + 20/15 = 13/6

Hence, using the greatest common factor we can simplify the fractions, and the least common multiple we can perform operations on the fractions.
