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.

…..

because boys number is 7 and girl number is 10 so

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.

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

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]

If both pairs of opposite sides of a quadrilateral are congruent then the quadrilateral is a parallelogram

Answer:   39.25

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

Work Shown:

d = diameter = 10

r = radius = d/2 = 10/2 = 5

A = area of a full circle

A = pi*r^2 = 3.14*5^2 = 78.5

Cut this in half to get the area of a semicircle (aka half circle)

(78.5)/2 = 39.25

This result is approximate.

Answer:

I am assuming any number in between these two, so let's just say 6,550.

Step-by-step explanation:

If you count up from 6,534, you will eventually get to 6,550. If you continue to count up, you will eventually reach 6,565 which is bigger than 6,550.

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.

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]
