Sandra is selling cookie dough for a fundraiser. She has a minimum fundraising goal of $150. If Sandra's mom gave her a $45 contribution without buying anything and Sandra can sell a box of cookie dough for $5 each, which inequality below represents the minimum number of cookie dough boxes she can sell
Answer:
At least 21 cookieStep-by-step explanation:
Firstly she needed to raise $150
and each cookie $5
let the number of cookie be x
let the expression for the fund raising be
150=5x
given that the mom gave her $45
then she need
150-45=5x
105=5x
x=105/5
x=21
Therefore she need to sell at least 21 cookie

the ratio of berries to oranges is 10:1 if there are 25 oranges, how many berries are there?
Answer:
250 berries
Step-by-step explanation:
There are 10 berries to every orange there is. It is given that there are 25 oranges. Simply multiply 10 with 25:
10 x 25 = 250
There are 250 berries.
~
Answer:
There are 250 berries.
Step-by-step explanation:
There are 10 berries per 1 orange.
We have 25 oranges.
To find out how many groups of berries to oranges there will be I will divide 25 by 1.
[tex]25/1=25[/tex]
[tex]x*y=z[/tex]
x = Amount of groups
y = Amount of berries per group
z = Amount of berries total.
Substitute values:
[tex]25*10=250[/tex]
There are 250 berries total!

What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
According to the given figure, vertices of rectangle ABCD are:
A=(3,0) B=(1,0) C=(1,2) and D=(3,2)
After the transformation of square ABCD we get a rectangle A′B′C′D′.
whose vertices are, A'=(6,0) B'=(2,0), C'=(2,2) and D'=(6,2)
(Here A', B', C' and D' are transformed from points A, B , C and D respectively.
In horizontal stretch by a factor k the point (x,y) in a graph f(x) is transformed to the (kx,y).
And after seeing the coordinates of vertices of square ABCD and rectangle A′B′C′D′
it is clear that there is no change in the y-coordinates in all the vertices of both square ABCD and rectangle A′B′C′D'.
Moreover, the x-coordinates are increasing by multiplying 2. Therefore it is a horizontal stretch by factor 2.
Hence, this transformation is a horizontal stretch by a factor of 2 .

plz simplify and answer 3x+7x−28+31−8x for x=2043
Answer:
4091
Step-by-step explanation:
Given the equation;
3x + 7x − 28 + 31 − 8x
First, we would collect like terms;
3x + 7x − 8x − 28 + 31
Simplifying, we have;
[tex] 2x + 5[/tex]
For x = 2043;
2(2043) + 5 = 4086 + 5 = 4091.

Here are the values of the first 5 terms of 3 sequences: : 30, 40, 50, 60, 70, . . . : 0, 5, 15, 30, 50, . . . : 1, 2, 4, 8, 16, . . . For each sequence, describe a way to produce a new term from the previous term. If the patterns you described continue, which sequence has the second greatest value for the 10th term? Which of these could be geometric sequences? Explain how you know.
Answer:
1,2,4,8,16.
Step-by-step explanation:
they are a square root of 2 for each question. it will eventually get up higher then additive.
The sequence that has the second greatest value for the 10th term is
1, 2, 4, 8, 16, . . .
The geometric sequences in the given sequences is 1, 2, 4, 8, 16, . . .
What is a sequence?A sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
Now the given sequences are,
30, 40, 50, 60, 70, . . . :
0, 5, 15, 30, 50, . . . :
1, 2, 4, 8, 16, . . .
For sequence 30, 40, 50, 60, 70, . . . :
we have common difference, d = 10
So, this is an arithmatic sequence.
So, Tn = a1 + (n-1)d
Hence, 10th term of the series,
T10 = 30 + (10-1)10
T10 = 30 + 9*10
T10 = 30 + 90
T10 = 120
For sequence 0, 5, 15, 30, 50, . . .
This is a recurssive sequence
Hence each term of the series is given as,
0
5 = 5*1
15 = 5*(1 + 2)
30 = 5*(1 + 2 + 3)
50 = 5*(1 + 2 + 3 + 4)
.
.
.
.
.
10th term = 5*(1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)
10th term = 225
For sequence 1, 2, 4, 8, 16, . . .
Here common ratio, r = 2
also, Tn = ar^(n-1)
So, T10 = 1*2^(10-1)
or, T10 = 1*2^9
or, T10 = 512
Therefore,
The sequence that has the second greatest value for the 10th term is
1, 2, 4, 8, 16, . . .
and The geometric sequences in the given sequences is
1, 2, 4, 8, 16, . . .

14. A cable company charges a $30 base installation fee plus $10 for every hour it takes to install all the equipment in your house. Write an equation in slope-intercept form that models the price of your installation as a function of the amount of time it takes.

The equation of line q is 5y - 4x = 10. Write an equation of the line that is perpendicular to q and passes through the point (-15, 8)
Answer:
y = -5/4x - 10.75
Step-by-step explanation:
First, put the equation in slope intercept form by isolating y:
5y - 4x = 10
5y = 4x + 10
y = 4/5x + 2
Perpendicular lines have opposite reciprocal slopes, so the slope will be -5/4
Plug in the slope and the given point into y = mx + b to find b:
y = mx + b
8 = -5/4(-15) + b
8 = 18.75 + b
-10.75 = b
Plug in the slope and y intercept into y = mx + b
y = mx + b
y = -5/4x - 10.75
Answer:
5x + 4y + 43 = 0
Explanation:
y=mx+b
m=slope
b=y intercept
perpendicuar lines have slopes that multiply to get -1
so
solving for y
add 4x both sides and divide by 5 to get
y=4/5x+2
slope is 4/5
perpendicular means the slopes multiply to get -1
so
4/5 times what=-1?
what=-5/4
so
y=(-5/4)x+b
find b
given the point (-15,8)
8=(-5/4)(-15)+b
8=75/4+b
-43/4=b
y=(-5/4)x-43/4
convert to standard form:
5x + 4y + 43 = 0
