Answer:
Yes; they should charge $3.30 for an apple and $2.00 for an orange.
Step-by-step explanation:
We can answer this question by creating some simultaneous equations.
Let [tex]x[/tex] = an apple and let [tex]y[/tex] = an orange.
With the information given, we can say that the price for an apple and an orange is equal to $5.30 while the price for an apple and 2 oranges is equal to $7.30.
Therefore:
[tex]x+y = 5.30[/tex] (1st equation)
[tex]x + 2y = 7.30[/tex] (2nd equation)
There are a couple of ways to solve these equations but I'll show you the substitution method. This is when we substitute the value of one of the equation into the other one.
So let's re-arrange one of them.
[tex]x+y=5.30[/tex] can be re-arranged into [tex]x= 5.30-y[/tex]
Now we know the value of [tex]x[/tex], we can replace the [tex]x[/tex] in the second equation.
Therefore [tex]5.30-y + 2y=7.30[/tex]. We can simplify this to give us [tex]5.30 + y = 7.30[/tex] and re-arrange to solve for y: [tex]y = 2[/tex].
Now we know the value of y, let's put it into the first equation:
[tex]x+2 =5.30[/tex]
and solving for [tex]x[/tex] we get: [tex]x = 3.30[/tex].
Therefore the price of an apple ([tex]x[/tex]) is $3.30 and the price of an orange ([tex]y[/tex]) is $2.
From the list of answers, there is only one correct option which is:
- Yes; they should charge $3.30 for an apple and $2.00 for an orange.

Question 7 of 10
These box plots show daily low temperatures for a sample of days in two
different towns.
Degrees (F)
Which statement is the most appropriate comparison of the spreads?
Answer:
A
Step-by-step explanation:
In a box plot, interquartile range (IQR) can be used to describe the spread of any given data.
IQR = Q3 - Q1
✔️IQR for Town A:
Q3 = 40
Q1 = 20
IQR = 40 - 20 = 20°
✔️IQR for Town B:
Q3 = 30
Q1 = 20
IQR = 30 - 20 = 10°
We can conclude that the IQR for town A, 20°, is greater than the IQR for town B, 10°.
what basic trigonometry identity would you use to identify that sin x cos x tan x = 1 - cos^2x
Answer:
tanx = sinx/cosx
Step-by-step explanation:
Given the expression
sin x cos x tan x = 1 - cos^2x
According to trigonometry identity
tan x = sinx/cosx
Substitute into the expression. From LHS
sin x cos x tan x
= sin x cos x (sinx/cosx)
= sin²x
Also since sin²x+cos²x = 1
Hence sin²x = 1 - cos²x (RHS)
The correct option is therefore tanx = sinx/cosx
Find the volume of a pyramid with a square base, where the perimeter of the base is 10.1\text{ ft}10.1 ft and the height of the pyramid is 13.4\text{ ft}13.4 ft. Round your answer to the nearest tenth of a cubic foot. Find the volume of a pyramid with a square base, where the side length of the base is 6.1\text{ m}6.1 m and the height of the pyramid is 4.7\text{ m}4.7 m. Round your answer to the nearest tenth of a cubic meter.
Answer:
28.5 ft^3
58.3 m^3
Step-by-step explanation:
volume of a pyramid = 1/3 x length x width x height
Perimeter of a pyramid = 4 x length
10.1 = 4 x length
length = 10.1 / 4 = 2.525
1/3 x (2.525 x 2.525 x 13.4) = 28.5 ft^3
1/3 x (6.1 x 6.1 x 4.7) = 58.3 m^3
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

Answer:
Step-by-step explanation:
vehicle one is traveling at a greater speed. from the graphs we can see that in one hour the care would travel 40 miles.
the table shows the 2nd vehicle traveling 30 miles in one hour
So car 1 is going faster :)
Answer:
Vehicle 1 is Moving Faster.
Step-by-step explanation:
For vehicle 1.
(2,80) (3,120)
∆Distance= 120-80 = 40miles
∆time = 3-2=1hr
So V=Distance/time = 40miles/1hr
V1 = 40miles per hour.
For car 2.
∆Distance=240-150 =90miles
∆time=8-5 = 3hrs
V=90/3
V=30Miles per hour.
So Car1 is Moving faster and at a velocity of 40Miles per hour.

156 divided by 3 with remaining
Answer: 52
Step-by-step explanation:
Divide 156 by 3, you get 52 with a remainder of 0.
In long division, you would write it as:
To perform the division, start by dividing 3 into the first digit of 156, which is 1.
3 ) 156 ( 52
- 15
_______
6
-6
_______
0
3 cannot go into 1, so you move to the next digit, 15. 3 can go into 15 five times (3 * 5 = 15). After subtracting 15 from 15, you have 0.
Now, you bring down the last digit, 6, to form 6. Since 3 can go into 6 two times (3 * 2 = 6), the final quotient is 52, and the remainder is 0.
In summary, 156 divided by 3 is equal to 52, with no remaining or fractional parts.

what is the value of x
Answer:
8
Step-by-step explanation:
Lines have angles that are equal to 180. Therefore, because we already have 140 of the 180 necessary, we can subtract 140 from 180 to get 40. 40 divided by 5 is 8.
Hope that this helps!
Answer:
I. x=8
Step-by-step explanation:
lines form 180° angles so
140 +5x= 180 ; subtract 140 from both sides
5x= 180-140; divide both sides by 5
x= 40/5 = 8

What is the area of this Triangle? Geometry.
======================================================
Explanation:
Refer to the diagram below. I've added point labels A,B,C to the corners of the rectangle. A in the upper left corner, B in the upper right, C in the lower right.
The area of the rectangle is
length*width = AB*BC = 6*4 = 24 square units.
We'll use this value later, so let m = 24
----------------
The area of triangle IAK is
base*height/2 = KA*AI/2 = 2*4/2 = 8/2 = 4 square units
We'll use this value later, so let n = 4
----------------
Repeat the idea of the last section, but do so for triangle KBJ
area = base*height/2
area = JB*BK/2
area = 3*4/2
area = 12/2
area = 6
Triangle KBJ is 6 square units. Let p = 6 so we can use it later.
------------------
Lastly, triangle JCI has area of...
area = base*height/2
area = IC*JC/2
area = 6*1/2
area = 3
Let q = 3
-------------------
To summarize everything so far, we have
m = 24 = area of entire rectanglen = 4 = area of triangle IAKp = 6 = area of triangle KBJq = 3 = area of triangle JCIAs you can probably guess where this is going, we'll subtract off the areas of the smaller triangles (n, p and q) from the overall larger rectangle (m) to get the area of triangle IJK.
m - n - p - q = 24 - 4 - 6 - 3 = 11
Triangle IJK has an area of 11 square units.
-------------------
An alternative method involves using this outline
Use the distance formula to find the side lengths IK, IJ, and KJThen use Heron's Formula to find the area of the triangle.Aşağıda verilen kesirlerin yüzde sembolü kullanılarak verilen gösterimlerden hangisi yanlıştır A 3/4=%75 B 2/4=%50 C 8/25=%32 D 15/75=%12

Carly buys 3 more band concert tickets than choir concert tickets. Band concert tickets cost $3.50 per ticket. What is the cost for the choir concert and band concert tickets?
Answer:
I'm not to sure, but I'll say 10.5
If you multiply 3.50 x 3 you'll get 10.5
If you add you'll get 13.5.
If it's an addition I'll recommend to go with 13.5
If it's a multiplication I'll recommend to go with 10.5

Answer:
$103
Step-by-step explanation:
Your living room is carpeted but you have allergies, and need to cover the 9 points floor with hardwood panel flooring. The panel flooring at Lowes cost $3.19 per square foot. (scale: 1m = 3.28 ft) Hint: Each unit contains 32.29 square feet. How much will it cost to purchase the flooring panels? (round to the nearest cent)
From the above question:
1 square foot = $3.19
32.29 square feet = x
Cross Mulitiply
x = 32.29 × $3.19
x = $103.0051
Approximately to the nearest cent = $103
Therefore, it will cost $103 to purchase the flooring panels

Why to solve this question
Answer:
35°, 70°, 75°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
x + 2x + 75 = 180
3x + 75 = 180 ( subtract 75 from both sides )
3x = 105 ( divide both sides by 3 )
x = 35
2x = 2 × 35 = 70°
The angles in the Δ are 35°, 70°, 75°
The three angles of the triangle are 75°, 70° and 35°.
Step-by-step explanation:
We know that,
Sum of angles of a triangle = 180°
⇢ 75° + 2 x + x = 180°
⇢ 3x = 180° - 75°
⇢ 3x = 105°
⇢ x = [tex] \frac{105}{3} [/tex]
⇢ x = 35°

determine the y intercept in the slope intercept form of an equation y=mx+b given a table x:4,6,8 y: 10,12,14
==========================================================
Explanation:
Let's use the first two rows of the table to find the slope
m = slope
m = rise/run
m = (change in y)/(change in x)
m = (y2-y1)/(x2-x1)
m = (12-10)/(6-4)
m = 2/2
m = 1
The slope is 1.
Now let's use the first row of the table, along with the slope we just found, to plug into y = mx+b. The goal is to find b.
y = mx+b
10 = 1*4+b
10 = 4+b
10-4 = b
6 = b
b = 6
The y intercept is 6.
The y = mx+b equation is y = 1x+6 which is the same as y = x+6
