Write the formula for the parabola that has x- intercepts (1.3,0) and (-1.3,0), and y- intercept (0,169).
Answer:
The y intercept is (0,1.69) and not (0,169)
Step-by-step explanation:
substituting, y=-1(x+1.3)(x-1.three) observe that this is distinction of squares y=-[x2-(1.3)2] , y=-(x2-1.69), y=-x2+1.69

Diego has 48 chocolate chip cookies, 64 vanilla cookies, and 100 raisin cookies for a bake sale. He wants to make bags that all have three cookie flavors and the same number of each flavor per bag.
How many cookies of each type are in each bag if he can make 16 bags without having any cookies left over?
Answer:
16
Step-by-step explanation:
48 - cc
64- v
100 - rc
43/3 = 16
64/3 = 21
100/3 = 33,(3)
Max number of bags is 16.

In Britain a Value Added Tax (VAT) of 17% is added to most purchases. If a skit costs $58.50 including tax, what is the price of the skirt before tax?
Answer:
i think it is 45.70
Step-by-step explanation:
Answer:
$48.55
Step-by-step explanation:
Make 17% into a decimal Multiply 0.17 and the number of Britain Value including tax Then take that number and subtract it by the number of Britain Value including taxEquation:
17% = 0.17
Why? The symbol % is called the percent sign. The expression 17% means 17 parts out of 100. Therefore, 17% is equivalent to the common fraction and to the decimal fraction 0.17.
0.17 × (Britain Value Including Tax) 58.50 = 9.945 to be exact but I rounded it up to 9.95 for easier use
58.50 - 9.95 = 48.55
So $48.55 is your answer
I hope this helped! Brainliest highly appreciated! Tell me if this is wrong I would like to know :) All of this written and solved by me. Except for the italic explanation of how to make 17% a decimal. You are free to use this explanation if needed so don't feel hesitant to copy and paste this.

There is a closed carton of eggs in Mai's refrigerator. The carton contains eggs and it can hold 12 eggs.
What does the inequality e<12 mean in this context?
Answer:
The maximum amount of eggs (represented by e) the egg carton can hold is 12.
(btw you cld give me the eggs if ur not gonna eat em' XD)
7th grade math <3 pls help heh
Answer:
a. 12a + 3b
b. 5b + 3a
Step-by-step explanation:
Which terms have the same thing applied to them? This is what I ask myself while figuring these out.
a. 5 and 7 both are multiplied by a, so you can combine the expressions to make 12a.
b. 10b - 5b = (10 - 5)b
Both 10 and 5 are multiplied by b, so you can just subtract the integers to get 5b.
I hope this helped!

Alyson is restocking her pantry. She buys 4 kinds of canned soup: tomato (T), mushroom (M), vegetable (V), and chicken noodle (N). She also buys garlic croutons (G) and cheese croutons (C) to pair with the soups. Which TWO statements are TRUE for this situation?
A.{ T, M, V, N, G, C} is the sample space.
B.{TG, TC, MG, MC, VG, VC, NG, NC} is the sample space.
C.There are 8 serving combinations.
D.{T, M, V, N} is the sample space.
E.There are 6 serving combinations.
Answer:
A and D would be your 2 sample spaces
Step-by-step explanation: because we can see its clearly not C or E so that leaves us with A , B, and D. I belive that B isnt a asnswer choice so that leaves A, and D
mark me brainless please it helps me
hope this helps
I would say A and D
There is no way that E and C are the answer. B is a no because TG…? What does TG mean? Some of the letters in choice B doesn’t make sense to me.

Nina created this pattern using trapezoid tiles.
How many unit trapezoids will be in pattern 16?
Answer: 256 trapezoids

The constant of Proportionality is 8.
What is constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
Total Baseball Caps= 30
Total amount of Cap= $240
let the number of caps sold be c.
Then, the equation is
30 c= 240
and, c= 240/30
c= 8
Hence, the constant of Proportionality is 8.

1) (3/2 m - 5n) (3/2 m + 5n)
Answer:
(3/2 m)^2 -(5n)^2^
Step-by-step explanation:
Answer: 9m^2 / 4 - 25n^2
Step-by-step explanation:
Use the identity: (a-b)(a+b)=a^2 - b^2
substitute values of a and b, where a=3/2m and b=5n.
The following simplifies to (3/2m)^2 - (5n)^2.
