Betty is baking cakes to sell slices in her bakery. Each cake has 8 slices. She carefully adds an icing design, using 1/3 cup of icing for each slice. If she plans to bake 4 1/2 cakes, how many cups of icing will she use?
Answer: 12 cups
Step-by-step explanation:
Number of slices in a cake = 8 slices
Number of cups of icing used by each slice = 1/3
Number of cups of icing for each cake will then be:
= 1/3 × 8
= 8/3
= 2 2/3 cups of icing
If she plans to bake 4 1/2 cakes, the number of cups of icing will she use will be:
= 4 1/2 × 2 2/3
= 9/2 × 8/3
= 72/6
= 12 cups of icing
Simplify this please (multi choice)

What is the value of 624 to the power of 1/4
Any number raised to a fraction just means that you take the number to the power of the numerator of the fraction and then root it by the denominator of the fraction.
In [tex]\frac{1}{4}[/tex], we raise 624 to [tex]1[/tex] and then root it by [tex]4[/tex] which gives:
[tex]\sqrt[4]{624^1}[/tex] = [tex]\sqrt[4]{624} =[/tex] approximately [tex]5[/tex] as [tex]5^4[/tex] is [tex]625[/tex].

The sum of two number is 18. 5 times the first number subtracted from 4/7bof the second number is 14. Find the number
Answer:
Required numbers are x = -0.5 and y =18.6
Step-by-step explanation:
Let the two numbers be x and y
Their sum is 18 i.e x+y= 18
4/7y-5x= 14
We need to find the numbers x and y
Solving both equations to find value of x and y
[tex]x+y= 18 ----(1)\\\frac{4}{7} y-5x= 14 ------(2)[/tex]
From equation 1 we can find value of x and put in equation 2 i.e
x=18-y
Putting the value of x in equation 2
[tex]\frac{4}{7}y-5(18-y)=14\\Solving:\\\\\frac{4}{7}y-90+5y=14\\\frac{4y-90*7+5*7y}{7}=14\\ \frac{4y-630+35y}{7}=14\\4y+35y-630=14*7\\39y=98+630\\y=728/39\\y=18.6[/tex]
Now finding x
[tex]x=18-y\\x=18-18.6\\x=-0.5[/tex]
So, Required numbers are x = -0.5 and y =18.6

Make t the subject of the formula
t = (3m -1) / (m - 1)
What is subject of formula?The subject of a formula is the variable that is being worked out. It can be recognized as the letter on its own on one side of the equals sign.
In order to change the subject of a formula, or rearrange a formula, items in the formula need to be rearranged so a different variable is the subject. Knowledge of solving equations and inverse operations is very useful.
Given formula.
m = t + 1 / t - 3
m ( t - 3) = t - 1
mt - 3m = t - 1
mt - t = 3m - 1
t(m - 1) = (3m - 1)
t = (3m -1) / (m - 1)
Hence, the formula becomes t = (3m -1) / (m - 1).

Find the equation of the linear function represented by the table below in slope-intercept form. x y 1 -9 2 -13 3 -17 4 -21
Answer:
3
Step-by-step explanation:
The linear function or equation in the slope-intercept form will be y = -4x - 5.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
The linear function is given as,
y = mx + c
Here, m is the slope while c is the y-intercept.
Slope m = (-13 + 9)/(2 - 1)
m = -4
Put m = -4, (1,-9)
-9 = -4(1) + c
c = -5
y = -4x - 5
Hence "The linear function or equation in the slope-intercept form will be y = -4x - 5".

Find the slope of the line that goes through the given points. (-7, - 8) and (-2, 9)
Answer:
17/5 or 3.14
Step-by-step explanation:
Slope (m) = ΔY/ΔX = 17/5 = 3.4
ΔX = -2 + 7 = 5
ΔY = 9 + 8 = 17
Distance (d) = √ΔX2 + ΔY2 = √314 = 17.720045146669

general formula (y-y1)= m(x-x1)
m is the slope and in this case m=-1/5
(x1, y1) is a point on thhe line in this case is (0, 7) because f(x)=y
substitute your given in the equation
