If you only have a 1 3 cup measuring cup and a recipe calls for 5 1 3 cups of flour, how many 1/3 cups would you need to use?
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.
What are equation models?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.

While shopping at the mall, Tom bought 3 hats and 4 pairs of glasses and spent $123. His friend Jerry bought the same type of items consisting of 1 hat and 3 pairs of glasses and spent $66. How much does a pair of glasses cost? How much does a hat cost?
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.

439
H
a
104°
K
76
measure of angle H =
measure of angle K = 137
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]

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]

HELP ME FIND MIDPOINT
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.

Need help solving this linear equation
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).
What is the slope of the line represented by this equation?
-3x + 8y = 12
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.
What number is in between 6534 and 6565
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.
