Answer:
The first store
Step-by-step explanation:
Given data
Let us find the unit cost on each sale
A price for pineapples is $5 for two pineapples
Unit cost per pineapple
=5/2
=$2.5 per pineapple
price for pineapple is $8 for four pineapples
Unit cost
=8/4
=$2 per pineapple
Hence the first store offers the lowest price per pineapple $2.5

Solve for x and y
4x+y=23
3x-y=12
Answer: y = 3, x = 5
Step-by-step explanation:
Solution by substitution method
4x+y=23
3x-y=12
Suppose,
4x+y=23→(1)
and 3x-y=12→(2)
Taking equation (1), we have
4x+y=23
⇒y= -4x+23→(3)
Putting y= -4x+23 in equation (2), we get
3x-y=12
3x-1(-4x+23)=12
⇒3x+4x-23=12
⇒7x-23=12
⇒7x=12+23
⇒7x=35
⇒x=5→(4)
Now, Putting x=5 in equation (3), we get
y=-4x+23
⇒y=-4(5)+23
⇒y=-20+23
⇒y=3
∴y=3 and x=5
Answer:
(x,y)=(5,3)Step-by-step explanation:

Answer: On interval f(x) is increasing = [tex]( -\infty, -2)[/tex]
On interval f(x) is decreasing = [tex]( -\infty, -2)[/tex]
Step-by-step explanation:
The given function: [tex]f(x)=-(x+2)^2+4[/tex]
The graph of the function is attached below
In graph , function is increasing till point (-2,4) or x=-2 and then it is decreasing.
So f(x) is increasing in [tex]( -\infty, -2)[/tex] and decreasing in [tex](-2, \infty)[/tex]
So, On interval f(x) is increasing = [tex]( -\infty, -2)[/tex]
On interval f(x) is decreasing = [tex]( -\infty, -2)[/tex]

Step-by-step explanation:
1.
3x + 7 + 10x + 17 = 180 ( property of inside angles of 2 parallel lines)
13x + 24 = 180
13x = 180 - 24 = 156
c = 156/13
x = 12.

As the triangle is a right triangle:
42.7 + N = 90
N = 90 - 42.7
= 47.3. degrees.
Answer:
for the first question it will be
Step-by-step explanation:
first make the equation from the numbers you see, (3x+7)+(10x+17)=180
the 180 comes from the lines that the equations are on both of the equations add up to 180 degrees,
then first add all like numbers [(3x+10x) + (7+17) = 180]= 13x+24=180
next subtract the non-variable number (forgot the term for it)
13x+24=180
-24 -24
13x=156
then divide the number in front of the variable
13x=156
13 13
x=12
then once you divide the answer is shown so you can put it in

You go to the outlet mall with a friend and buy a jacket for $49.00 and new Vans for $55.00. Sales tax in Texas is 8.25%. How much did you spend on these two items after tax? *
Answer:
Amount spent after sales tax = $112.58
Step-by-step explanation:
Given that:
Cost of jacket = $49.00
Cost of new Vans = $55.00
Total spent = 49.00 + 55.00 = $104.00
Sales tax = 8.25%
Amount of sales tax = [tex]\frac{8.25}{100}*104[/tex]
Amount of sales tax = $8.58
Total after sales tax = 104.00 + 8.58 = $112.58
Hence,
Amount spent after sales tax = $112.58
A right triangle has legs of length 7 and 3. What is the length of the hypotenuse?
Answer:
sqrt 58
Step-by-step explanation:
7^2+3^2=c^2
c=[tex]\sqrt{58}[/tex]
Answer:
sqrt(58)
Step-by-step explanation:
Use the Pythagorean Theorem.
a^2 + b^2 = c^2
3^2 + 7^2 = c^2
9 + 49 = c^2
58 = c^2
c = sqrt(58)
Answer: sqrt(58)
725% work in an organisation 52% of employees or post graduate and the remaining are not post graduate find the number of employees were not post graduate
Answer: 348
Step-by-step explanation:
Given : Total employees work = 725
Proportion of employees are post graduate = 52%
Proportion of employees are not post graduate = 100%-52% = 48%
The number of employees were not post graduate = 48% of 725
= 0.48 x 725
= 348
Hence, the number of employees were not post graduate = 348

Answer:
The shape is a kite and x=26
Step-by-step explanation:
The shape is a kite because the two adjacent sides at the right match and the two sides on the left match
To find x:
125+125=250
360-250=110
(3x-11)+(2x-9)=110
Combine like terms: 5x-20=110
Add 20 to both sides: 5x-20+20=110+20
5x=130
Divide both sides by 5: 5x/5=130/5
x=26
Leah took her friends for a ride in her hot air balloon. The function f models the height of the hot air balloon about the ground ( in meters) as a function of time (in minutes) after takeoff.
Question:
Leah took her friends for a ride in her hot air balloon.
The function r(t) = 210 - 15t models the height of the hot air balloon about the ground (in meters) as a function of time (in minutes) after takeoff.
Explain what r(10) means in the context of the real-world scenario, and how to find its value.
Answer:
The balloon reaches a height of 160 meters, 10 minutes after take off.
Step-by-step explanation:
Given
[tex]r(t) = 210 - 5t[/tex]
Required
Explain r(10)
First, we calculate r(10)
Substitute 10 for t in [tex]r(t) = 210 - 5t[/tex]
[tex]r(10) = 210 - 5 * 10[/tex]
[tex]r(10) = 210 - 50[/tex]
[tex]r(10) = 160[/tex]
Hence: r(10) means that the balloon reaches a height of 160 meters, 10 minutes after take off.

2 (4m-5) - (6m-11) =33
Answer:
m = 16
Step-by-step explanation:
2(4m - 5) - (6m - 11) = 33 (Given)
8m - 10 - 6m + 11 = 33 (Distribute)
2m + 1 = 33 (Combine like terms)
2m = 32 (Subtract 1 on both sides)
m = 16 (Divide 2 on both sides)
You can check by substituting your answer into the equation:
2(4(16) - 5) - (6(16) - 11) = 33
2(64 - 5) - (96 - 11) = 33
2(59) - (85) = 33
118 - 85 = 33
33 = 33
