Answer:
The inequality sign is not correct because the > symbol means greater than. However, up to and including $90 can be spent so the inequality sign should be ≥ (greater than or equal to).
The best description of the error in the student's inequality is; The inequality symbol should be Greater-than-or-equal-to instead of > since up to and including $90 may be spent.
What is the representation of the inequality?We are told that;
Amount for the class to spend = $90
Cost of field trip = $2.5 per person
Number of persons on the trip = 5 persons
Inequality used by a student is;
90 > 2.5(x + 5)
The inequality sign used above is not correct because the they have $90 to spend and so the inequality sign should be ≥ (greater than or equal to).

One interior angle of a triangle is 60°. The other angle measures are x° and yº. Which of the following could be the values of
x and y? Select all that apply. X = 60, y = 60
X = 100, y = 20
X = 40, y = 80. x=50, y = 90
X = 45, y = 45
Answer:
x=60, y= 60
x=100, y= 20
x=40, y=80
Step-by-step explanation:
Triangles add up to 180 degrees. The ones above added to 60 equal 180.
60+60+60=180
100+20+60=180
40+80+60=180

A line has slope = 0 and goes through the point (1, 6). What is the equation of the line in slope-intercept form?
a) y = 1
b) y = 6
c) x = 1
d) x = 6
Answer:
y = 6.
Step- by-step explanation:
A slope of 0 means that the line is horizontal and would be of the form y = k.
As is pass through the points where y = 6 ( 1, 6) :- it is y = 6.

PLEASE EXPLAIN IT IS SUPER DUPER URGENT Explain how to find the area of a triangle if the height of the triangle is 24 ft and the base of the triangle is 8 ft. Please use complete sentences and mathematical words. Minimum of 5 sentences.
Answer:
You have to multiply 24 and 8, which will give you 192. For a triangle, you always must divide by two, and doing so on this equation will give you 96. Like everything involving area, or something with a measurement, you must use the proper measurement unit, in this case that would be feet. In all, the answer is 96 feet for the overall area of the triangle. The formula for this process is A=[tex]\frac{hb}{2}[/tex]
Step-by-step explanation:
Answer:
Step-by-step explanation:
This is how you find the area of a triangle. First, you must use the formula

f(2) = -8 +16 + 3
f(2) = 11
Maximum value is 11
Answer:
11
Step-by-step explanation:
it has a vertex at (2,11)
.
f(2) = 11
how to find the vertex;
function equation is f(x) = ax^2 + bx + c
we can find x by :-b/2a, -8/-4 = 2
and by putting the x value we get the y

Please help! A robotic vacuum cleaners can clean 2 square feet of carpet in 8 minutes. About how long does it take for it to clean a carpet covering a room with the dimensions shown below?
Answer: 6480
Step-by-step explanation: So since the dimensions are easy to calculate, just multiply 9 by 4 and 15 by 3, then you get 36 and 45. Multiply 36 by 45 and you get 1620, but since the vacuum can get 2 square ft, then divide by 2 and you get 810. Since it takes 8 minutes to clean up, multiply 810 by 8 and you get 6480. I do believe

Answer:
Area = 52√3
A
Step-by-step explanation:
Remark
This is a trapezoid. The formula for a trapezoid is Area = 1/2 (b1 + b2)* h/2
Givens
b1 = 11
b2 = 15
h = 4*√3
Solution
Area = 1/2 (15 + 11 )*4*√3
Area = 1/2(26)*4√4
Area = 13 * 4√3
Area = 52√3

Answer:
44ft
Step-by-step explanation:
The formula for circumference is 2 * π * radius and in this case we want to use 3.14 for π and so we do 2 x 3.14 x 7 because the radius is half of the diameter (14) and once you do that you end up getting 43.96 and once you round you get 44ft so you are correct.

if this is the given data 24, 12, 19, 26, 19, 20, 15, 17 what is the median
Answer:
24 i'm pretty sure sorry if i am wrong
Step-by-step explanation:
Answer:
19
Step-by-step explanation:
The median is the middle number of a data set. To find it, you need to put the numbers in order:
12, 15, 17, 19, 19, 20, 24, 26
Then I like to cross off a number from each end, then one more, working my way toward the middle. Doing this, you're left with 19 and 19 in the middle. When you have 2 numbers, you average them. In this case, you don't have to. The median is 19.

Step-by-step explanation:
[tex]x^{2}[/tex] / x - 1 - 6x - 7/ x - 1
(it's the equation shown in the picture, you might have typed it wrong on your question)
The equation has the same denominator so, it will become:

The answer is below
Step-by-step explanation:
A linear function graph can be represented by:
y = mx + b; where m is the slope and b is the y intercept, x is the independent variable and y is the dependent variable.
a) From the graph we can see the graph passes through the point (0, 100) and (20, 400). Hence we can use the following formula to find the equation:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-100=\frac{400-100}{20-0}(x-0)\\\\y-100=15x\\\\y=15x + 100[/tex]
b) An example of real life linear function is the energy consumed per day in kWh. Let us assume 5 kWh is consumed each day by the person. Since the independent variable is the days, it would be on the x axis, while the dependent variable (energy consumed) would be on the y axis.

5. A cook needs 10 pounds of flour. He wants to spend the least amount of money. A 2-
pound bag costs $1.59 and a 5-pound bag costs $2.89, which should he buy in order to spend
less money? *
Answer:
He should buy two of the 5-pound bag.
Step-by-step explanation:
The cook needs 10 pounds of flour.
He wants to spend the least amount of money.
First option is a 5-pound bag for $2.89 each.
He can get 2 of the 5-pound bag which equals 10 pounds of flour for 2 x $2.89 = $5.78
Second option is a 2-pound bag for $1.59 each.
He can get 5 of the 2-pound bag which equals 10 pounds of flour for 5 x $1.59 = $7.95.
Second option is $2.17 costlier than the first option.
So, he should go for 2 of the 5-pound bag in order to spend the least amount of money while shopping for 10 pounds of flour.

A girls feet are 4 over 6 yards from the surface of the pool a boys feet are 1 over 6 yards from the surface detemin whose feet are closer to the surface
Answer:
Boy's feet is closer
Step-by-step explanation:
Given that :
Distance from Surface of pool :
Girl's feet : 4/6 yards = 2/3 yards
Boy's feet : 1/6 yards
Comparing the two distances ;
2/3 = 0.6666
1/6 = 0.1666
Hence, 2/3 > 1/6
Therefore, distance between the boy's feet and the surface is lesser and hence closer than the girl's feet
