The students in Mary’s class sold cookies for a fundraiser this year and last year. This year, the selling price of a box of cookies was $13.25. The price this year represents 6% more than the selling price of each box last year.
Find 6% of 13.25
0.06 x 13.25 = 0.795
Then subtract 0.795 from 13.25 because the price was less last year
13.25-0.795 = 12.455
Rounded up that would be $12.46 last year

Given the functions f(x) = 10x 25 and g(x) = x 8, which of the following functions represents f[g(x)] correctly? f[g(x)] = 10x 33 f[g(x)] = 10x2 33 f[g(x)] = 10x 105 f[g(x)] = 10x2 105.
The function f[g(x)] = 10x+105 will represent the function
What will the be the function f[g(x)]?We have two functions
[tex]F(x)=10x+25[/tex]
and
[tex]g(x)=x+8[/tex]
To find f[g(x)] put the value of g(x) in F(x)
[tex]F(g(x)=10(x+8)+25[/tex]
[tex]F(g(x)=10x+80+25[/tex]
[tex]F(g(x)= 10x+105[/tex]

Which of the following has a slope of 3 and y-intercept of 4
Answer:
see attached
Step-by-step explanation:
The slope is the ratio of the change in y to the change in x. The y-intercept is the function value when x=0.
__
A table demonstrates a y-intercept of 4 if the y-value for x=0 is 4. It demonstrates a slope of 3 if the y-value increases by 3 when the x-value increases by 1.
A graph demonstrates a y-intercept of 4 when the line crosses the y-axis at y=4. It demonstrates a slope of 3 if it rises 3 grid squares for each grid square it runs to the right.
The table and graph indicated in the attachment both show a slope of 3 and a y-intercept of 4.

Find the area of the parallelogram:
Answer:
40cm²
Step-by-step explanation:
[tex]Solution,\\Here,\\\\Height(h)=5cm\\\\Base(b)=8cm\\\\Now,\\\\Area=base*height\\\\Area=8cm*5cm\\\\Area=40cm^{2}[/tex]
Question :-
Find the Area of Parallelogram whose Height is 5 cm and the Base is 8 cm .Answer :-
Area of Parallelogram is 40 cm² .Explanation :-
As per the provided information in the given question, we have been given that the Height of the Parallelogram is 5 cm . Its Base is given as 8 cm . And, we have been asked to calculate the Area of Parallelogram .
For calculating the Area , we will use the Formula :-
[tex] \bigstar \: \: \: \boxed{ \sf{ \: Area \: _{Parallelogram} \: = \: Base \: \times \: Height \: }} [/tex]
Therefore , by Substituting the given values in the above Formula :-
[tex] \dag \: \: \: \sf {Area \: _{Parallelogram} \: = \: Base \: \times \: Height} [/tex]
[tex] \longmapsto \: \: \sf {Area \: _{Parallelogram} \: = \: 8 \: \times \: 5} [/tex]
[tex] \longmapsto \: \: \bf {Area \: _{Parallelogram} \: = \: 40} [/tex]
Hence :-
Area of Parallelogram = 40 cm² .[tex] \underline {\rule {180pt} {4pt}} [/tex]

An engineer was supposed to draw a line exactly 7/10 centimeters long. An error was made, and he drew the line 9/10 centimeters long. How much longer than needed was the line the engineer drew?
Answer:
2/10 or 1/5 if you want it simplified
Step-by-step explanation:
9/10 is basically 9 and 7/10 is 7 so 9 - 7 is 2 and we need to add the /10 back so it's 2/10 or 1/5
Step-by-step explanation:
want to draw=7/10

find jh in triangle HIJ
Answer:
2
[tex]2 \times area \div height \:[/tex]
Step-by-step explanation:
the answer is 5
Answer:
JH=16
Step-by-step explanation:
Hi there!
We are given ΔHIJ, where HI is parallel to KL, and that JK=10, JI=40, and JL=25
We want to find JH
We can use something called the Triangle Proportionality Theorem to help us find JH
The Triangle Proportionality Theorem essentially states that if there is a line parallel to one of the sides of a triangle that intersects the other 2 sides of that triangle, then that segment divides those sides proportionally
In other words, KL is parallel to HI and intersects both HJ and JI, and JK, JH, JL, and JI create a proportion, which is [tex]\frac{JK}{JH} =\frac{JL}{JI}[/tex]
We can substitute the values that we know into that equation
[tex]\frac{10}{JH} =\frac{25}{40}[/tex]
We can simplify 25/40 to 5/8.
[tex]\frac{10}{JH} =\frac{5}{8}[/tex]
Now we can cross multiply (use the means-extreme theorem)
Multiply 10 and 8 together, and set that equal to 5 times JH
80 = 5JH
Divide both sides by 5
16=JH
Hope this helps!

Four friends share the profit of a lawn care service equally. the friends charge $45 per lawn and spend $30 of their total earnings on gasoline for the lawnmowers each week. which inequality can be used to find m, the number of lawns they need to mow next week so that each person earns at least $275? startfraction 45 m minus 30 over 4 endfraction greater-than-or-equal-to 275 startfraction 45 m over 4 endfraction minus 30 greater-than-or-equal-to 275 startfraction 45 m minus 30 over 4 endfraction less-than-or-equal-to 275 startfraction 45 m over 4 endfraction minus 30 less-than-or-equal-to 275
Inequality can be used to find m will be 45m - 30 ≥ 1100. Inequality is an opinion of an ordering relationship between two digits or algebraic terms,
What is inequality?
inequality is a statement of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.
The amount charged for lawn= $45
"m" is the total number of lawns they move per week. Because they charge $ 45 per lawn, the total amount they will charge for m lawns will be $ 45m.
Every week, they spend $ 30 of their whole earnings on gasoline. As a result, each week's total earnings will be
45m-30
Everybody wants to make at least $275. Because there are four of them, the total they aim to earn is at least
The total amount has to be earned for the four friends=4 x 275 = $ 1100
We need to figure out how many lawns they'll have to move in the following week to earn at least $1100. The equation is as follows:
45m - 30 ≥ 1100
This disparity may be used to find m, the number of lawns they need to mow next week to earn at least $275 for each participant. This can be solved in the following way:
45m ≥ 1130
m ≥ 25.11
We round up the number of lawns to 26 to guarantee they earn at least $ 1100 in total because the number of lawns must be a whole number.
we get m ≥ 26.
Hence inequality can be used to find m will be 45m - 30 ≥ 1100.

The function a(n) = 3(2)^n represents the value of the nth term in a sequence. What is the sum of the 1st and 4th terms of the sequence
Answer:
54
Step-by-step explanation:
We are given the sequence or function:—
[tex]\displaystyle \large{a(n) = 3(2)^n}[/tex]
To find the sum of 1st term and 4th term, first we must find the first term and the fourth term which can be done by substituting n = 1 and n = 4.
[tex]\displaystyle \large{a(1)=3(2)^1}\\\displaystyle \large{a(1)=3 \cdot 2}\\\displaystyle \large{a(1)=6}[/tex]
Then when n = 4.
[tex]\displaystyle \large{a(4) = 3(2)^4}\\\displaystyle \large{a(4) = 3 \cdot 16}\\\displaystyle \large{a(4) = 48}[/tex]
Therefore, the sum of 1st term and 4th term is:—
[tex]\displaystyle \large{a(1)+a(4) = 6+48}\\\displaystyle \large{a(1)+a(4)=54}[/tex]
