The total number of cups of flour that Rebecca will need to bake three cakes is 369 cups of flour.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that the recipe for one cake calls for 123 cups of flour. Also, Rebecca needs to bake three cakes, therefore, the total number of cups of flour that Rebecca will need is,
Total number of cups of flour = Number of cakes × Number of cups of flour in a cake
= 3 cakes × 123 cups of flour per cake
= 369 cups of flour
Hence, the total number of cups of flour that Rebecca will need to bake three cakes is 369 cups of flour.

The length of the base of a rectangle is 6 less than 3 times the width. The perimeter of the rectangle is 52 inches. What is the length of the base?
Answer:
The rectangle has a width of 18 inches and a height length of 8 inches.
Step-by-step explanation:
The perimeter of a rectangle is described by the equation:
[tex]p = 2w + 2l[/tex]
where l is width, h is height, and p is perimeter.
We're also told that the total perimeter is 52 inches.
We're also told that the length is six inches less than three times the width. We can express that as [tex]w = 3l - 6[/tex].
We can plug that definition of w into the perimeter equation to find the length:
[tex]p = 2w + 2l\\52 = 2(3l - 6) + 2 * l\\52 = 6l - 12 + 2l\\52 + 12 = 8l\\8l = 64\\l = 64/8\\l = 8[/tex]
Now we can take that and the given perimeter, and substitute those into the perimeter equation to find the width:
[tex]p = 2w + 2l\\52 = 2w + 2(8)\\52 = 2w + 16\\36 = 2w\\w = 36 / 2\\w = 18[/tex]
So the width is 18

Marie is saving money for home repairs. To date, she has saved $1,195. She needs at least $1,483 for the repairs. She plans to set aside $32 per week to add to her current savings. If this situation is modeled by the inequality below, how many more weeks, x, does she need to continue saving in order to have enough money for the repairs?
Answer:
Number of weeks= 9
Step-by-step explanation:
First, we need to calculate the money required to reach the objective:
Money required= 1,483 - 1,195
Money required= $288
Now, we can determine the number of weeks left to accumulate $288 and get to $1,483:
Number of weeks= 288 / 32
Number of weeks= 9

Step-by-step explanation:
The given triangles are similar, meaning that their corresponding sides are proportional.
The length of DC (I think its D) is 15 and the length of WZ is 3. ZY is in the same place as CE (16). Make a proportional relationship where Δ→Δ:
[tex]\frac{large}{small} =\frac{large}{small}[/tex]
[tex]\frac{DC}{WZ}=\frac{CE}{ZY}[/tex]
Insert the known values:
[tex]\frac{15}{3}=\frac{16}{x}[/tex]
x is the value of ZY. Solve by cross multiplying:
[tex]15(x)=3(16)\\\\15x=48[/tex]
Divide both sides by 15:
[tex]\frac{15x}{15} =\frac{48}{15} \\\\x=3.2[/tex]
ZY is 3.2.

Find the value of the monomial. 5x^3 for x=0.5
Answer:
The correct answer is 166.375 or 166.4 when rounded to the nearest tenth.
Step-by-step explanation:
If x = 0.5, then 5x^3 = 5.5^3.
5.5^3 is the same as multiplying 5.5 by itself 3 times.
5.5 x 5.5 x 5.5 = 166.375 or 166.4 when rounded to the nearest tenth.

Step-by-step explanation:
Step 1: Define equation
-2x + 6 = -20
Step 2: Solve for x
Subtract 6 on both sides: -2x = -26Divide -2 on both sides: x = 13Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -2(13) + 6 = -20Multiply: -26 + 6 = -20Add: -20 = -20Here we see that -20 does indeed equal -20.
∴ x = 13 is the solution to the equation.

Given that f(x) = x2 – 5x – 14 and g(x) = x – 7, find (f +g)(x) and
express the result in standard form.
Answer:
[tex](f+g)(x)=x^2-4x-21[/tex]
Step-by-step explanation:
We are given:
[tex]f(x)=x^2-5x-14\text{ and } g(x)=x-7[/tex]
And we want to find:
[tex](f+g)(x)[/tex]
This is equivalent to:
[tex]=f(x)+g(x)[/tex]
Therefore, by substitution:
[tex]=(x^2-5x-14)+(x-7)[/tex]
Rearranging gives:
[tex]=(x^2)+(-5x+x)+(-14-7)[/tex]
Combine like terms:
[tex]=x^2-4x-21[/tex]

The roots of the given polynomial are ±3/7 and ± [tex]\frac{\sqrt{3} }{\sqrt{7} }[/tex].
What is a polynomial ?A polynomial has 2 or more than two terms connected by mathematical operations.A polynomial of degree n has n no. of roots real or imaginary.
A polynomial can be formed as a₁xⁿ + a₂xⁿ⁻¹ + a₃xⁿ⁻² + ...+ aₙx⁰.
According to the given question we have to solve a polynomial of degree 4.
Given, 49k⁴ - 9 = 0
49k⁴ = 9
k⁴ = 9/49
k² = 3/7
k = [tex]\frac{\sqrt{3} }{\sqrt{7} }[/tex].
We know that a polynomial of degree n has n no. of roots.So a polynomial of degree 4 have 4 roots and they are ±3/7 and ± [tex]\frac{\sqrt{3} }{\sqrt{7} }[/tex].
