[tex]7.25 \leqslant x[/tex]
Step-by-step explanation:
you do 1.5×8 to see how much shipping cost
you get 12 then subtract 12 from 70 and you get 58, then you do 58÷8 and you get $7.25
so he needs to spend $7.25 or more on each friend. (im pretty sure)
The amount urgio needs to spend on each gift in order to receive free shipping is 7.25.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Given that urgio wants to buy gifts for 8 friends. he wants to gie the same gife to all his friends and he plans to have all the gifts wrapped in additional charge for 1.50 dollars each.
Let the cost of each gift = c
urgio is buying gifts for 8 friends = 8 gifts
Hence, the Inequality equation is written as:
(c + $1.50)× 8 ≥ $70
8c + 12 ≥ 70
8c ≥70 - 12
c ≥ 58/8
c≥ 7.25
Therefore, the amount urgio needs to spend on each gift in order to receive free shipping is 7.25

Jada wanted to construct a line perpendicular to line e
through point C. The diagram shows her construction.
What was her mistake?
Answer:
Here the mistake is that she drew a circle from the point A to intersect the line rather the drawing arcs from the point C
The next another circle was drawn from the point of the intersection of the first circle and the intersection of both circles was used to draw the perpendicular at the midpoint of the intersection of both circles.
Step-by-step explanation:
To construct a line perpendicular to another line through a point the following steps are required
1) From the point, with the compass, C draw to intersect the line at points A and B
2) From A and B with the compass made wider, draw arcs above and below the line to intersect each other
3) With the straight edge Draw a line passing through the intersections of the arcs drawn from A and B and extend the line to pass through the point C
The line constructed above is the perpendicular to the line l passing through the point C.
To undo multiplication, you
A.divide
B.mulitpy
C. add
D. subtract
Answer:
A
Step-by-step explanation:
It’s the opposite
Answer: In order to undo multiplication you must divide. For fractions multiply the reciprocal to get it to the other side in an equation.
Step-by-step explanation:
So it is given that we have to do the opposite operation of multiplication, so that is division. In an equation, if we have a fraction, then we multiply the reciprocal of the fraction to get it to the other side.

11(n-1)+35=3n what is the answer
Answer:
n = -3
Step-by-step explanation:
Original Equation:
11 (n-1) + 35 = 3n
Distributive Property:
11n + 24 = 3n
Subtract 24 from both sides:
11n + 24 - 24 = 3n - 24
Simplify:
11n = 3n - 24
Subtract 3n from both sides:
11n - 3n = 3n - 24 - 3n
Simplify:
8n = -24
Divide both sides by 8:
[tex] \frac{8n}{8} = \frac{ - 24}{8} [/tex]
Simplify:
n = -3
Answer:
n=-3

Multiply (3x)(x2 + 4x - 15).
(3 x3 + 12 x2 - 45 )
3 x + 12 x - 45 x3)
(4 x3 + 3 x + 12 x2 - 15 )
(3 x4 + 12 x3 - 45 )
Answer:
3x^3 + 12x^2 - 45x
Step-by-step explanation:
Multiply 3x with x^2 then 4x and then -15 in order
3x × x^2 = 3x^3
3x × 4x = 12x^2
3x × (-15) = -45x now add the expressions
3x^3 + 12x^2 - 45x

3. Is this relation a function? (-1,5) (-3, 6) (-2, 9) (5, 11) (-3, 6) (4, 11) (0, 10)
Answer:
Yes, it is.
Step-by-step explanation:
A function is a relation between two sets of elements, where each valid input can be mapped to exactly one output.
Indeed, the relation in this question is between two sets of elements. Each of these pairs includes exactly two elements: the input and the output.
On the other hand, does this relation maps each valid input to exactly one output? Arrange these pairs by the input in increasing order:
Input: [tex]-3[/tex]; Output: [tex]6[/tex].Input: [tex]-3[/tex]; Output: [tex]6[/tex].Input: [tex]-2[/tex]; Output: [tex]9[/tex].Input: [tex]-1[/tex]; Output: [tex]5[/tex].Input: [tex]0[/tex]; Output: [tex]10[/tex].Input: [tex]4[/tex]; Output: [tex]11[/tex].Input: [tex]5[/tex]; Output: [tex]11[/tex].Indeed, the input [tex]-3[/tex] appeared twice in the list. However, in both occurrence, this input mapped to the same output, [tex]6[/tex]. This relation is still a function.
A car rental agency charges a fee of $35 per day plus $.20 for each mile driven. How much will it cost to rent the car for 4 days and drive 730 miles? Your answer should include a $ and two decimal places, in the format $10.00
Answer:
$271.00. Remember to put it in the right format
Step-by-step explanation:
So since its 35 dollars per day, we can first do 35*4 to get 140. So just for having the car, it costs 125 dollars.
Now to find the amount of money for the miles, we can do 730*0.20=146
Now we add those two amounts so we do 125+146=271.
So $271.00
89, 74, 100, 86, 74, 67, 86, 72, 60, 93, 83, 86 what is the median?
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{84.5}}}}}[/tex]
Step-by-step explanation:
Given data :
89 , 74 , 100 , 86 , 74 , 67 , 86 , 72 , 60 , 93 , 83 , 86
Arranging the data in ascending order, we have,
60 , 67 , 72 , 74 , 74 ,83 , 86 , 86 , 86 , 89 , 93 , 100
Here, n ( total no.of observation ) = 12
Now, finding the position of media :
[tex] \boxed{ \sf{position \: of \: median = ( \frac{n + 1}{2} ) ^{th} \: item}}[/tex]
⇒[tex] \sf{ (\frac{12 + 1}{2} ) ^{th} item}[/tex]
⇒[tex] \sf{( \frac{13}{2} ) ^{th} item}[/tex]
⇒[tex] \sf{ {6.5}^{th} item}[/tex]
6.5 th item is the average of 6 th and 7 th items.
Again,
[tex] \sf{median = \frac{ {6}^{th \: item} + {7}^{th} item}{2} }[/tex]
⇒[tex] \sf{ \frac{83 + 86}{2} }[/tex]
⇒[tex] \sf{ \frac{169}{2} }[/tex]
⇒[tex] \sf{84.5}[/tex]

Christina goes to the market with $25. She buys one papaya for $4 and has the rest of the money for bananas. Each banana costs $0.55. Write an inequality for the number of bananas she can purchase.
Answer:
0.55x+4<=25
Step-by-step explanation:
It would be 0.55x because x is the number of bananas and 0.55 is the cost and the 4 represents the $4 she spent for a papaya. The 25 is the amount of money she has so it says less than or equal to because she only has so much money.

Little Johnny is fleeing from a horde of zombies. He is 4000 feet from a safe zone where a gate will be closed in 3 minutes. If Johnny is running at a rate of 22 mph, will he be able to reach the safe zone before the gate is closed? Yes or No? Explain BRIEFLY.
Answer:
Johnny will be able to reach the safe zone before the gate is closed.
Step-by-step explanation:
Given that:
Distance of Little Johnny from safe zone = 4000 feet
Time = 3 minutes
Speed = 22 mph
To find:
Will Johnny be able to reach the safe zone ?
Solution:
Johnny can only be safe if he can travel 4000 feet in 3 minutes with the given speed.
Let us try to find out, the distance that he can travel in 3 minutes at speed of 22 mph.
Let us have a look at the formula of distance traveled:
[tex]Distance = Speed \times Time[/tex]
Time = 3 minutes = [tex]\frac{3}{60}[/tex] hrs
Speed = 22 mph
[tex]Distance = 22 \times \frac{3}{60}\\\Rightarrow Distance = \dfrac{22}{20}\ miles \\\Rightarrow Distance = 1.1\ miles[/tex]
We know that 1 mile = 5280 feet
Therefore 1.1 miles = 5280 [tex]\times[/tex] 1.1 feet = 5808 feet
Distance traveled by Little Johnny is greater than 4000 feet.
Therefore Johnny will be able to reach the safe zone before the gate is closed.

A grocery clerk changes the display of oranges regularly. If the pattern indicated
below is continued, determine the number of oranges that will be displayed on
the 8th figure. Use a table to find the pattern.
Answer:
36
Step-by-step explanation:
F1 = 1
F2 = 1 + 2
F3 = 1 + 2 + 3
--> The n(th) figure has the number of oranges = the sum of the first n natural numbers, which has the general form:
F(n) = 1 + 2 + 3 + ... + n = n(n+1) / 2
So, 8th figure has:
F(8) = 8.(8+1) / 2 = 8 . 9 / 2 = 36

What is the solution to 7x + 6y if y = 10 and x = 2?
Answer: First we will substitute the numbers in place of the variables in the equation, and then we will use order of operations to solve.
7x + 6y would be equal to:
7(2) + 6(10)
Now we will perform the multiplication:
7 * 2 = 14
6 * 10 = 60
The equation now looks like:
14 + 60
This is equal to 74. Your answer is therefore 74.
Hi there! Hopefully this helps!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Answer: 74First we need to evaluate the variables into the expression.
7x + 6y = 7(2) + 6(10).
6 x 10 = 60
7 x 2 = 14.
60 + 14 = 74
The parabola y=x^2 is shifted down 2 units and is reflected. What is the new parabola?
