Answer:
4
Step-by-step explanation:
The proportional equation that represents the situation is k=2/3.
Given that, Jacqui needs 8 cups of sugar to make 12 batches of cookies.
We need to find what is the proportional equation that represents the situation.
What is the proportional equation?Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. The proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.
Based on the type of relationship two or more quantities share, the proportion can be classified into different types. There are two types of proportions.
Direct ProportionInverse ProportionThe number of cups of sugar used to make batches of cookies is a direct proportion.
8∝12
⇒8=12k
⇒k=8/12
⇒k=2/3
Therefore, the proportional equation that represents the situation is k=2/3.

Please help me by answering the following questions!!
Answer:
1. A number having 2, 3, 7 or 8 at unit's place is never a perfect square. In other words, no square number ends in 2, 3, 7 or 8. The number of zeros at the end of a perfect square is always even. In other words, a number ending in an odd number of zeros is never a perfect square.
2. Only those numbers, when squared will have 6 at their unit place are 4 and 6 Because 4×4 = 16 and 6×6 = 36(i dont know if this is what you were looking for)

Answer:
0.1458 in decimal form.
Step-by-step explanation:
In mathematics, every integer is a rational number, hence a whole number 8 can be written as 8/1. 7/6 ÷ 8 = 7/48 in fraction form.
7/6 ÷ 8 = 0.1458 in decimal form.

1. Set up the proportion: StartFraction 9 over 6 EndFraction = StartFraction x over 16 EndFraction
2. Use cross product: 9(16) = 6x
3. Simplify:
144 =
4. Divide:

Answer:
x = 24
Step-by-step explanation:
9/6 = x/169(16)= 6x144 = 6xx = 144/6x = 24Miranda and Savannah are excited that a new store just opened in town! They go together the first day it opens! Each time Miranda goes to the store she plans to spend $7dollar sign, and each time Savannah goes to the store she plans to spend $9.A few weeks from now, Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.
Answer:
Miranda made 9 visits to the store and Savannah made 7 visits to the store
Step-by-step explanation:
To find how many times Miranda and Savannah went to the store we would need to find the Greatest Common Multiple of the amount that each of them spends per visit. We do this by simply going through each of these numbers' times tables until we find a common one.
7 * 1 = 7 9 * 1 = 9
7 * 2 = 14 9 * 2 = 18
7 * 3 = 21 9 * 3 = 27
7 * 4 = 28 9 * 4 = 36
7 * 5 = 35 9 * 5 = 45
7 * 6 = 42 9 * 6 = 54
7 * 7 = 49 9 * 7 = 63
7 * 8 = 56
7 * 9 = 63
Finally, we can see that the first time that both Miranda and Savannah have spent the exact same amount would be when Miranda made 9 visits to the store and Savannah made 7 visits to the store. Each of which wasted $63

Sally baked 28 brownies with 4 scoops of flour. With 5 scoops of flour, how many cookies can she bake?
Answer:
28 brownies - 4 scoops
x brownies - 5 scoops
Cross multiply and we get:
140 = 4x
Divide both sides by 4:
140/4 = 4x/4
35 = x
Hence, 5 scoops of flour will bake 35 brownies

we are told that one broadcast shows commercial every 17minutes
and the other shows commercials every 14 minutes
now the time when they both sho commercial is given by the greates common multiple of the times 17 and 14
multiples of 17= 17,34,51,68,85,102,119,136,153,170,187,204,221,238
multiples of 14= 14,28,42,56,70,84,98,112,126,140,154,168,182,196,210,224,238

So you need to do f(x) 5x^2+3x-19+3
You would simplify the equation to get to y=4x+5f(x)+2
Naturally you would now graph the equation to a linear degree but still inducing a parabellum, y-(d-3)=0
Then solve using the square method (b/2)^2=(6)^2
Then put the 6 on both sides of the equation.
6^2+w0+8x+7t^2

Simplify the expression i⁸²
Answer:
We can use a trick here. Let's look at the first few exponents of i to realize this:
i^0 = 1
i^1 = i
i^2= -1
i^3 = -i
i^4 = 1
i^5 = i
i^6 = -1
i^7 = -i
we can see that the pattern (1, i, -1, -i) repeats. Since 82/2 = 41, and 41 is only divisible by 1, i^41 = i, and i^2 = -1. -1*i = -i, so i^82 = -i.

Complete the table of values for this absolute value function. Then use the drawing tool(s) to graph the function. F(x)-2|x+1|-1
Answer:
Please check the explanation!
Step-by-step explanation:
Given the equation
[tex]f\left(x\right)=-2|x+1|-1[/tex]
As some of the absolute rules are:
[tex]\left|a\right|=a,\:a\ge 0[/tex][tex]\:|-a|=a,\:\quad \:a>0[/tex]NOW, let us solve!
Let us substitute all the table values
Putting x = -4
[tex]y=-2\left|-4+1\right|-1[/tex] ∵[tex]\mathrm{Apply\:absolute\:rule}:\quad \left|a\right|=a,\:a\ge 0[/tex]
[tex]y=-6-1[/tex]
[tex]y=-7[/tex]
So, when x = -4, then y = -7
Putting x = -3
[tex]y=-2|-3+1|-1\:[/tex]
[tex]y=-4-1[/tex]
[tex]y=-5[/tex]
when x = -3, then y = -5
Putting x = -2
[tex]y=-2\left|-2+1\right|-1[/tex]
[tex]y=-2-1[/tex]
[tex]y=-3[/tex]
when x = -2, then y = -3
Putting x = -1
[tex]y=-2\left|-1+1\right|-1[/tex]
[tex]y=-0-1[/tex]
[tex]y=-1[/tex]
when x = -1, then y = -1
Putting x = 0
[tex]y=-2\left|0+1\right|-1[/tex]
[tex]y=-2-1[/tex]
[tex]y=-3[/tex]
when x = 0, then y = -3
Putting x = 1
[tex]y=-2\left|1+1\right|-1[/tex]
[tex]y=-4-1[/tex]
[tex]y=-5[/tex]
when x = 1, then y = -5
