There are 32 vanilla cupcakes and 40 chocolate cupcakes at a bakery. All of the cupcakes must be placed in boxes with the same number of vanilla cupcakes and the same number of chocolate cupcakes in each box.
Answer:
5 to 4
Step-by-step explanation:
when it's asking for a ratio it's basically division
chocolate/vanilla = 40/32 = 5/4
5/4 is the same as 5:4 or 5 to 4

Which of the sets of ordered pairs represents a function?
A = {(3, −5), (4, 6), (3, 9), (2, 7)}
B = {(2, 4), (−1, 4), (5, 4), (4, 4)}
a
Both A and B
b
Only B
c
Only A
d
Neither A nor B
Answer:
B
Step-by-step explanation:
A does not represent a function because the x-value of 3 appears twice, and by the defenition of a function, the x-value cannot appear twice for it to be considered a function. B could be a function because the x-values are not repeated.
Therefore the answer is B, only B is a function.

22 of the 30 students in Evan's grade have a pet. What is the ratio of the number of students who do not have a pet to the number of students who have a pet?
Answer:
8 to 22
Step-by-step explanation:
if there are 22 people that have a pet whens there is 30 students in total, you have to do, 30-22, and 30-22=8 meaning there are 8 students who don't have pets.
And if already says 22 students have pets, therefore the answer is
8 to 22

Answer:
a) 3.6 × 10²
Time = distance / speed
So time = 1.08 × 10⁸ / 3 × 10⁸
= 1.08 × 10¹¹ / 3 × 10⁸ ( converted 10⁸ km to meter )
= 1.08 × 10³ / 3
= 0.36 × 10³
. = 3.6 × 10²
Time = 3.6 × 10²
If x=2, y=4, m= -1, and n=3 find the value of :
X^m+n * y^n-m/ x^m-n * y^n+m
Answer:
The value is [tex]\frac{1}{16384}[/tex]
Step-by-step explanation:
Here we need to find
[tex]\frac{x^{m+n}\cdot y^{n-m}}{x^{m-n}\cdot y^{n+m}}=x^{m+n-(m-n)}\cdot y^{n-m-(n+m)}\\\\=x^{2n}\cdot y^{-2m}\\\\=2^{2\cdot-1}\cdot 4^{-2\cdot3}\\\\=\frac{1}{2^2\times4^6} \\\\=\frac{1}{16384}[/tex]

A taxicab charges $3.00 per person
plus $1.25 per mile. What is the
greatest distance one passenger
could travel with a budget of
$28.00?
Answer:
I believe the answer would be 20 miles max for one passenger.
Step-by-step explanation:
This is because if you create an equation out of this, knowing that only one passenger will be riding, you will get:
$3.00+$1.25x=$28 ($3 added too $1.25 times the number of miles (x) which equals the total amount you have ($28)).
x being the number of miles (so we need to calculate for x)
$3 + $1.25x = $28
-subtract 3 on both sides-
$1.25x=$28-$3
$1.25x=$25
-divide by 1.25 on both sides-
x=$25/$1.25
x=20 miles
Not sure if all calculations are correct, but I hope this helps :)!

What's the formula for the area of a triangle?
Answer:
A=hb/2
To calculate the area of a triangle, multiply the height by the width (this is also known as the 'base') then divide by 2. Find the area of a triangle where height = 5 cm and width = 8 cm. A triangle is always half the area of a rectangle with the same height and width.
Hey there!
“ What's the formula for the area of a triangle?”
The area of triangle formula is:
A = hbB/2
Whereas “hb” is your “height base” & “b” is your “base”
Good luck on your assignment and enjoy your day!

You can look at the question for an example of what the area of a triangle is

I'm assuming you meant to say [tex](x - 3)(2x^2 + 4x - 1)[/tex]
Let [tex]y = x-3[/tex]
So,

angle A and angle B are supplementary angles. If m∠=(4x - 30) degree and m∠B =(4x-14) degree, then find the measure of ∠A
Answer:
<A = 26°
Step-by-step explanation:
4x - 30 + 4x - 14 = 180
Supplementary angles sum together to make 180
=> 4x + 4x = 16x
=> -30-14 = -44
16x = 180+44
16x = 224
x = 224/16
x = 14°
4(14) - 30 = 26°
