Answer:

You would need 16 1/3 cups!

Step-by-step explanation:

I used an equation, but you could also use mental conversions! :

1/3c = 5 1/3

(1/3c)3 = (5 1/3)3 (multiply each side by 3 (3/1))

3c /3 = (48) /3 (divide each side by 3)

c = 16

:)

(c = cups!)

The requried number of 1/3 cups to make the recipe is 16.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

here,
Measuring cup = 1/3
Recipe required number of cups = 5 1/3 of flour,
Let the number of 1/3 cups = x
1/3x = 5 1 / 3
x/3 = 16 / 3
x = 16

Thus, the requried number of 1/3 cups to make the recipe is 16.

Answer: (-4, -7)

Step-by-step explanation: To solve this system of equations, we can use the substitution method.

To solve a system by substitution, we first need to isolate one of our variables. The problem is none of our variables has a coefficient of 1 or -1. In this situation, we have to look at our next best option.

In our first equation, add 2x to both sides to get

2y = -6 + 2x and just divide both sides by 2 to get y = -3 + x.

Now let's plug this value of y into our second equation.

So we have 3x + 7(-3 + x) = -61.

Simplifying from here:

3x - 21 + 7x = -61

10x - 21 = -61

10x = -40

x = -4

Since we know that x = -4, we can just plug a -4 into our equation that we created earlier to get y = -3 + (-4) or y = -7.

Since x = -4 and y = -7, our answer is the ordered pair (-4, -7).

The angle of depression from you to your friend is 54.1°

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let θ represent the angle between me in air and my friend, hence:

tanθ = 326 / 450

θ = 35.9 degrees

The angle of depression = 90 - 35.9 = 54.1°

The angle of depression from you to your friend is 54.1°

Answer:

a pair of glasses costs $17

a hat costs $21

Step-by-step explanation:

h = hat

g = glasses

3h + 4g = 123

1h + 3g = 66

multiply the 2nd equation by 3

3h + 9g = 198

negate everything in the 1st equation and add it to the 'new' 2nd equation

    3h  + 9g = 198

+  -3h  - 4g = -123

5g = 75

g = 15

substitute the 15 in either one of the 1st equations

1h + 3(15) = 66

h + 45 = 66

h = 66-45

h = 21

to check, substitute both g=15 and h=21 into BOTH 2 original equations.

If you would do this in whole number form, it'll be 40/7.

Answer:

∠H = 137°

∠K = 76°

Step-by-step explanation:

The sum of the interior angles of a trapezoid = 360°

In a trapezoid, the angles on the same leg (called adjacent angles) are supplementary, meaning they add up to 180°

The legs are the non-parallel sides:  JK and HI

Therefore, 104 + ∠K = 180

⇒ ∠K = 180 - 104 = 76°

And, ∠H + 43 = 180

⇒ ∠H = 180 - 43 = 137°

Sum of two adjacent angles in trapezium equals 180°

[tex]\\ \tt\hookrightarrow <H+43=180[/tex]

[tex]\\ \tt\hookrightarrow <H=180-43[/tex]

[tex]\\ \tt\hookrightarrow <H=137[/tex]

And

[tex]\\ \tt\hookrightarrow <K+104=180[/tex]

[tex]\\ \tt\hookrightarrow <K=180-104[/tex]

[tex]\\ \tt\hookrightarrow <K=76°[/tex]

Answer: (-1/2, 0) which is the same as saying (-0.5, 0)

================================================

Explanation:

The x coordinates of A and B are -2 and 1 respectively.

Add up those values to get -2+1 = -1

Then cut that result in half: -1/2 = -0.5

This is the x coordinate of the midpoint.

--------

Repeat for the y coordinates:

Add: 1 + (-1) = 0

Cut in half: 0/2 = 0

The y coordinate of the midpoint is 0

-------

Overall, the midpoint is located at (-1/2, 0) which is the same as writing (-0.5, 0). This is where the segment AB crosses the x axis.

Step-by-step explanation:

Turn the equation into a slope-intercept form equation:

[tex]8y=3x+12[/tex]

Divide each side by 8 to simplify y:

[tex]y=\frac{3}{8} x+1.5[/tex]

The slope is 3/8.

Using the format:

[tex]y=mx+b[/tex]

3/8 is in place of m, the slope.

Answer:

x = 7[tex]\sqrt{3}[/tex]

Triangle area formula: base * height * 1/2

We are given:

Base - 14 cm

Height - x

Using the pythagorean theroem (a^2 + b^2 = c^2) we can figure out the height.

We are given:

Side a - 14 / 2 = 7 cm

Side b - the height (x)

Side c - 14 (it's an equilateral triangle)

Now, substitute the given values:

7^2 + x^2 = 14^2

49 + x^2 = 196

x^2 = 147

x = [tex]\sqrt{147}[/tex]

x = 7[tex]\sqrt{3}[/tex]
