Stacey had 3 cakes for her party, She had 1/8 of a cake left after the party. How much cake was eaten at her party?
Answers
Answer: 3=24/8 24/8 - 1/8 = 23/8 or 2 7/8
Step-by-step explanation:
Exchange 3 into 24/8 which is still 3 but in 8th’s. Then subtract 1/8 from 24/8 which is 23/8 or 2 7/8
Answer:
23/8 or 2 7/8
Step-by-step explanation:
3 cakes means there is 8/8 in each cake.
So
8/8 + 8/8 + 8/8 = 24/8
Then Stacey is saying that she had 1/8 of 1 cake left, so if we subract 1/8 from 24/8 we will have our answer to be 23/8 or 2 7/8
The length of segment EF is 8 units, the length of segment ED is 10 units, and the length of segment EA is 13.33 units. Find the length of FA Explain or show your reasoning,
Answers
Answer:
5.33 unit
Step-by-step explanation:
logically FA = EA - EF = 13.33-8 = 5.33 units
Since, E, F and A all lie on the same line EA . The information ED= units is redundant. Therefore we can say that FA= 5.33 unit
The length of FA is 5.33 units
The given parameters are:
[tex]\mathbf{EF = 8}[/tex]
[tex]\mathbf{ED = 10}[/tex]
[tex]\mathbf{EA = 13.33}[/tex]
EF and EA implies that point E is between line FA
So, the length of FA is calculated using:
[tex]\mathbf{FA = EA - EF}[/tex]
Substitute known values
[tex]\mathbf{FA = 13.33 - 8}[/tex]
Subtract
[tex]\mathbf{FA = 5.33}[/tex]
Hence, the length of FA is 5.33 units

The temperature in a town was 0 °F at 7 a.m. Over the next 312 hours, the temperature rose at a steady rate to 20.3 °F.
What was the temperature at 8 a.m.?
Enter your answer as a decimal in the box.
°F.
Answers
Answer:
5.8
Step-by-step explanation:
First, convert 312 to a decimal:
12=1÷2=0.5
312=3.5
Divide.
20.3÷3.5=5.8
The temperature changed by 5.8 °F every hour. That means the temperature rose from 0 °F to 5.8 °F between 7 a.m. and 8 a.m.

Find an equation of the line passing through the points
(–3, –5) and (6, –2).
Answers
Answer:
y=1/3x-4
Step-by-step explanation:
1. Use the slope formula to find the slope of the two coordinates.
y2-y1/x2-x1
-2--5/6--3
3/9 = 1/3
The slope is 1/3
2. Choose one of the coordinates and plug them and the slope into the point-slope formula
y-y1=m(x-x1)
y+2=1/3(x-6)
3. Distribute and simplify.
y+2=1/3x-2
y=1/3x-4
Answer: y=1/3x-4
Explanation:
Begin by finding the slope of the line. You can do this by using the given ordered pairs and plugging them into the slope formula, y^2-y^1/x^2-x^1. Plugging them would appear as -2-(-5)/6-(-3). The resulting math would be 3/9 or 1/3 when simplified. Using the slope-intercept form, we can plug in the slope to make it y=1/3x+b. Choose any ordered pair to plug into the equation. I'm going to use (-3,-5). Plugging this in would result with -5=1/3(-3)+b. Multiply 1/3 and -3 to get -5=-1+b. Add -1 to both sides to get b=-4.

1.) Change the equation using factored transformation: [tex]4x^2-15x-4=0[/tex]- Quadratic polynomial can be factored using the transformation [tex]ax^2+bx+c=a(x-x_{1})(x-x_{2})[/tex], where [tex]x_{1}[/tex] and [tex]x_{2}[/tex] are the solutions of the quadratic equation [tex]ax^2+bx+c=0[/tex].
- This steps basically means change you current equation using the formula [tex]ax^2+bx+c=0[/tex].
2.) Turn the factored form into the quadratic equation form:[tex]x=\frac{-(-15)\frac{+}{}\sqrt{(-15)^2-4\bold{x}4(-4)}}{2\bold{x}4}[/tex]- All equations of the form [tex]ax^2+bx+c=0[/tex] can be solved using the quadratic formula: [tex]\sqrt{\frac{-b\frac{+}{}\sqrt{b^2-4ac}}{2a} }[/tex].

b)y=-9 x=2/3
c) y=8 x=3
d)y=-8 x=2
e)y=15.5 x=-6
hope this helps bro
The correct values are;
a) y = - 10, x = - 1
b) y = - 9, x = 2/3
c) y = 2, x = 3
d) y = - 8, x = 2
e) y = 6.5 , x = 6
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
There are some expressions.
Now,
Find all the values after substitute the values as;
a. y = 6x + 8
When x = - 3;
y = 6 × - 3 + 8
y = - 18 + 8
y = - 10
When y = 2,
y = 6x + 8
2 = 6x + 8
2 - 8 = 6x
- 6 = 6x
x = - 1
b. y = 3x
When x = - 3;
y = 3 × - 3
y = - 9
When y = 2,
y = 3x
2 = 3x
x = 2/3
c. y = - x + 5
When x = - 3;
y = - 3 + 5
y = 2
When y = 2,
y = - x + 5
2 = - x + 5
x = 5 - 2
x = 3
d. y = 2x - 2
When x = - 3;
y = 2 × - 3 - 2
y = - 6 - 2
y = - 8
When y = 2,
y = 2x - 2
2 = 2x - 2
2x = 2 + 2
2x = 4
x = 2
e. y = 1.5x + 11
When x = - 3;
y = 1.5 × - 3 + 11
y = - 4.5 + 11
y = 6.5
When y = 2,
y = 1.5x + 11
2 = 1.5x + 11
1.5x = 2 - 11
1.5x = - 9
x = 6
Thus, The correct values are;
a) y = - 10, x = - 1
b) y = - 9, x = 2/3
c) y = 2, x = 3
d) y = - 8, x = 2
e) y = 6.5 , x = 6

A store sold a case of candles for $17.85 that had been marked up 10%. what was the original price?
Answers
Step-by-step explanation:
The original price was $16.23
Explanation:
We can rewrite this problem as:
110% of what is $17.85.
"Percent" or "%" means "out of 100" or "per 100", Therefore 110% can be written as
110 x/100
.
When dealing with percents the word "of" means "times" or "to multiply".
Finally, lets call the number we are looking for "n".
Putting this altogether we can write this equation and solve for
n
while keeping the equation balanced:
110/100 × n = $17.85
110/100 × n = $17.85
110/100 × n = $17.85 100/110 × 110/100 × n = 100/110 × $17.85
110/100 × n = $17.85 100/110 × 110/100 × n = 100/110 × $17.85
100/110 <¬ cross out × 110/100 <¬ cross out × n = $ 1785/110
× n = $ 1785/110
n = $16.23n rounded to the nearest penny.

360-112=248 (it is 360 because the shape is a quadrilateral
and then, since the other angles left are congruent the you divide the 248 to 2, and the answer will be 124
so, 56+56+124+124=360
