the volleyball team needs new uniforms. the students plan to sell plush toy Eagles ( the school mascot) for $5 each. The students find three companions on-line that sell stuff mascots. Company A cell's 12 eagles for $34.08. Company B cells 15 equals for $42.90. Company C charges $50.58 for 18 eagles. which company has the Best Buy?
Answer:
Company C
Step-by-step explanation:
You divide the amount of money it all costs to the number of plushies they are selling it for.
A: 34.08/12 = $2.84 each
B: 42.90/15 = $2.86 each
C: 50.58/18 = $2.81 each
So C has the least amount of money spent for a greater amount of plushies so C would be the Best Buy.
Your fitness tracker overestimates the number of steps you take by 5%. The trackers indicates that you took 7350 steps today. Write and solve an equation to find the actual number of steps you took today.
The equation (1 + 0.05)x = 7350 to find the actual number of steps you took today will be 7,000.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
Your fitness tracker overestimates the number of steps you take by 5%. The trackers indicate that you took 7350 steps today.
Let x be the actual number of steps. Then the equation will be given as,
(1 + 0.05)x = 7350
x = 7350 / 1.05
x = 7,000
The actual number of steps you took today will be
(1 + 0.05)x = 7350
x = 7350 / 1.05
x = 7,000
The equation (1 + 0.05)x = 7350 to find the actual number of steps you took today will be 7,000.

Step-by-step explanation:
The 1000ths place is the 1 in 0.01
The 100ths place is the 1 in 0.001
A = 0.881
The number in the 1000ths place is 1

Pls help me!! ASAP I WILL GIVE BRAINLIEST Brandon's bread recipe calls for milk powder, sugar, and flour in a ratio of 2:3:15, respectively. How many pounds of each does Brandon need if the three ingredients together weigh 2 lb?
Answer:
0.2 pounds of milk
0.3 pounds of sugar
1.5 pounds of flour
Step-by-step explanation:
If we have the ratio [tex]2:3:15[/tex], then we know that all of these ingredients together will be [tex]15+3+2=20[/tex]. If we want the whole thing to weight 2 pounds, then the total weight of everything else will be [tex]20\div2=10[/tex] percent of the original.
So,
[tex]2\cdot0.1=0.2\\\\3\cdot0.1=0.3\\\\15\cdot0.1=1.5[/tex]
We can confirm this is correct because [tex]1.5+0.3+0.2=2[/tex].
Hope this helped!
Step-by-step explanation:
Simple formula [tex]\frac{item ratio}{total ratio}[/tex]×total amount
milk powder; ×2= 0.2 lb
sugar; [tex]\frac{3}{20}[/tex]×2= 0.3 lb

PLEASE HELP!! what is the equation for the parabolic function that goes through the points (-3, 67) (-1, 1) and has a stretch factor of 9
Answer:
[tex]f(x)=9(x+\frac{1}{6})^2-\frac{21}{4}[/tex]
Step-by-step explanation:
So, we need to find the equation of a parabolic function that goes through the points (-3,67) and (-1,1) and has a stretch factor of 9.
In other words, we want to find a quadratic with a vertical stretch of 9 that goes through the points (-3,67) and (-1,1).
To do so, we first need to write some equations. Let's use the vertex form of the quadratic equation. The vertex form is:
[tex]f(x)=a(x-h)^2+k[/tex]
Where a is the leading coefficient and (h,k) is the vertex.
Since a is the leading coefficient, it's also our stretch factor. Thus, let a equal 9.
Also, we have two points. We can interpret them as functions. In other words, (-3,67) means that f(-3) equals 67 and (-1,1) means that f(-1) equals 1. Write the two equations:
[tex]f(x)=a(x-h)^2+k\\f(-3)=67=9((-3)-h)^2+k[/tex]
And:
[tex]f(x)=a(x-h)^2+k\\f(-1)=1=9((-1)-h)^2+k[/tex]
Now, we essentially have a system of equations. Thus, to find the original equation, we just need to solve for the vertex. To do so, first isolate the k term in the second equation:
[tex]1=9(-1-h)^2+k\\k=1-9(-1-h)^2[/tex]
Now, substitute this value to the first equation:
[tex]67=9(-3-h)^2+k\\67=9(-3-h)^2+(1-9(-1-h)^2)[/tex]
And now, we just have to simplify.
First, from each of the square, factor out a negative 1:
[tex]67=9((-1)(h+3))^2+(1-9(((-1)(h+1))^2)[/tex]
Power of a product property:
[tex]67=9((-1)^2(h+3)^2)+(1-9((-1)^2(h+1)^2))[/tex]
The square of -1 is positive 1. Thus, we can ignore them:
[tex]67=9(h+3)^2+(1-9(h+1)^2)[/tex]
Square them. Use the trinomial pattern:
[tex]67=9(h^2+6h+9)+(1-9(h^2+2h+1))[/tex]
Distribute:
[tex]67=(9h^2+54h+81)+(1-9h^2-18h-9)[/tex]
Combine like terms:
[tex]67=(9h^2-9h^2)+(54h-18h)+(81+1-9)[/tex]
The first set cancels. Simplify the second and third:
[tex]67=36h+73[/tex]
Subtract 73 from both sides. The right cancels:
[tex]67-73=36h+73-73\\36h=-6[/tex]
Divide both sides by 36:
[tex](36h)/36=(-6)/36\\h=-1/6[/tex]
Therefore, h is -1/6.
Now, plug this back into the equation we isolated to solve for k:
[tex]k=1-9(-1-h)^2[/tex]
First, remove the negative by simplifying:
[tex]k=1-9((-1)(h+1))^2\\k=1-9((-1)^2(h+1)^2)\\k=1-9(h+1)^2[/tex]
Plug in -1/6 for h:
[tex]k=1-9(-\frac{1}{6}+1)^2[/tex]
Add. Make 1 into 6/6:
[tex]k=1-9(-\frac{1}{6}+\frac{6}{6})^2\\ k=1-9(\frac{5}{6})^2[/tex]
Square:
[tex]k=1-9(\frac{25}{36})[/tex]
Multiply. Note that 36 is 9 times 4:
[tex]k=1-9(\frac{25}{9\cdot4})\\ k=1-\frac{25}{4}[/tex]
Convert 1 into 4/4 and subtract:
[tex]k=\frac{4}{4}-\frac{25}{4}\\ k=-\frac{21}{4}[/tex]
So, the vertex is (-1/6, -21/4).
Now, plug everything back into the very original equation with 9 as a:
[tex]f(x)=a(x-h)^2+k\\f(x)=9(x+\frac{1}{6})^2-\frac{21}{4}[/tex]
And this is our answer :)
Find the value of (58.27 + 41.73) x 0.6341.

Answer:
Step-by-step explanation:
y=a(x-h)^2+k
-12=a(1-h)^2+k
16=a(3-h)^2+k
subtract
a(3-h)^2-a(1-h)^2=28
a[(3-h)^2-(1-h)^2]=28
a=2
2[(3-h)^2-(1-h)^2]=28
(3-h)^2-(1-h)^2=14
9+h^2-6h-(1+h^2-2h)=14
9+h^2-6h-1-h^2+2h=14
-4h+8=14
-4h=6
h=-3/2
16=2(3+3/2)^2+k
16=2×81/4+k
k=16-81/2=-49/2
so y=2(x+3/2)²-49/2
Answer: y=a(x-h)^2+k
-12=a(1-h)^2+k
16=a(3-h)^2+k
subtract
a(3-h)^2-a(1-h)^2=28
a[(3-h)^2-(1-h)^2]=28
a=2
2[(3-h)^2-(1-h)^2]=28
(3-h)^2-(1-h)^2=14
9+h^2-6h-(1+h^2-2h)=14
9+h^2-6h-1-h^2+2h=14
-4h+8=14
-4h=6
h=-3/2
16=2(3+3/2)^2+k
16=2×81/4+k
k=16-81/2=-49/2
so y=2(x+3/2)²-49/2

Find the number if 18 is taken away from 8 times of a number gives 30.
Answer:
Let the number be x.
8 times that number would be 8x, and taking away 18 from it 8x - 18. Knowing the result of doing this is 30, we can write the following equation:
8x - 18 = 30
And solve it. First we pass the -18 to the sight umming:
8x = 30 + 18
8x = 48
Then the 8 which is multiplying to the right dividig:
x = 48/8 = 6
Now we verify we have done it preporly:
8x - 18 = 30
8 * 6 - 18 = 30
48 - 18 = 30 TRUE
Answer:
x =6
Step-by-step explanation:
Translate into algebraic equation =
[tex]8(x)-18= 30\\= 8x-13=30[/tex]
Let's solve for x
[tex]\mathrm{Add\:}18\mathrm{\:to\:both\:sides}\\8x-18+18=30+18[/tex]
Simplify
[tex]8x=48[/tex]
Divide both sides by 8
[tex]\frac{8x}{8}=\frac{48}{8}[/tex]
Simplify
[tex]x =6[/tex]

A. 5 B. 4 C. 3 D. 2
Answer:
A: 5
Step-by-step explanation:
4x + y = 17 --> y = 17 - 4x
5x + 2y = 22
<=> 5x + 2 . (17 - 4x) = 22
<=> 5x - 8x + 34 = 22
<=> 34 - 3x = 22
<=> 3x = 34 - 22 = 12
<=> x = 4
y = 17 - 4x = 17 - 4 . 4 = 17 - 16 = 1
So, x + y = 4 + 1 = 5
