Answer:
each apple is £ 1.80
Step-by-step explanation:
i first multiplied the cost for one pear by 7, to get how much money was spent on pears out of the 12.70.
Then i took the remaining money and divided it by 2 to get how much each apple costs.
Answer:
1.80
Step-by-step explanation:
1) Price of Pears
[tex]1.30 * 7 = 9.10[/tex] formating: 1.30*7 = 9.10
2) Price of Apples
[tex]12.70 - 9.10 = 3.60[/tex] formating: 12.70-9.10 = 3.60
3) Price of Apples/Kg
[tex]\frac{3.60}{2} = 1.80[/tex] formating: 3.60/2 = 1.80

Answer:
Option D
Step-by-step explanation:
If (1, 6) is the only solution of the system of equations and one of system of equations is,
y = 2x + 4
Then solution of the system will satisfy both the equations.
Option A
y = 4x - 7
By satisfying this equation by (1, 6),
6 = 4(1) - 7
6 = -3
False.
Therefore, given equation is not the answer.
Option B
y = 2x + 8
By satisfying this equation by (1, 6),
6 = 2(1) + 8
6 = 10
False.
Therefore, given equation is not the answer.
Option C
y = -2(x + 2)
By satisfying this equation by (1, 6),
6 = -2(1 + 2)
6 = -6
False.
Therefore, given equation is not the answer.
Option D
y = 5x + 1
By satisfying this equation by (1, 6),
6 = 5(1) + 1
6 = 6
True.
Therefore, this is one of the equations of the system of equations.
Option D is the answer.
Select the correct answer.

Which figures can have the same cross section as a sphere?
Answer:
2
Step-by-step explanation:
the cross section of a sphere is a circle
only the cone can have a circle for a cross section
The figure of cone can have the same cross section as a sphere.
What are similar figures?Similar figure are zoomed in or zoomed out (or just no zoom) version of each other. They are scaled version of each other, and by scale, we mean that each of their dimension(like height, width etc linear quantities) are constant multiple of their similar figure.
For two similar figures, the pair by pair similar angles of those two similar figures are called corresponding angles. They are of same measurement.
When we slice a given object vertically (perpendicular to the ground level), then the sliced surface is called vertical cross section.
Here we can see that the cross section of a sphere is a circle and only the cone can have a circle for a cross section.
So, the answer is option 2.

Answer:
25² · 40 π in.³
Step-by-step explanation:
V = πr²h
π · 25² · 40
≈ 78539.81634
Since your question wants it in a different way, you have to know the formula.
V = πr²h
V = r² · h π in³
v = 25² · 40 π in³

Answer:
Step-by-step explanation:
5²+10²=25+100=125
13²=169
so 5²+10²≠13²
so it is not a right angled triangle.

A train travels 120 mi in 1 hour and 20 minutes. How many miles will the train go in 6 hours traveling at the same rate?
Answer: 541.32 miles
Step-by-step explanation:
First find the speed of the train in miles per hour.
1 hour 20 minutes needs to be converted to decimal:
= 1 20/60
= 80/60
= 1.33 hours
Speed is:
= Distance / Time
= 120/ 1.33
= 90.22 miles an hour
If the train is traveling 6 hours at the above speed, it will travel:
= Speed * time
= 90.22 * 6
= 541.32 miles

Answer:
Step-by-step explanation:
<2 + <1 + 20 = 180 A straight line has 180 degrees.
<2 is given as 90 degrees.
90 + <1 + 20 = 180 Combine like terms
<1 + 110 = 180 Subtract 110 from both sides
<1 = 180 - 110
<1 = 70
<1 + <2 + <3 = 180
<1 = 70
<2 = 90
70 + 90 + <3 = 180
160 + <3 = 180 Subtract 160 from both sides
<3 = 180 - 160
<3 = 20
20 + 20 + <4 = 180 Straight line theorem stated above.
40 + <4 = 180 Subtract 40 from both sides
<4 = 180 - 40
<4 = 140

A survey from summer 2019 found that the average American adult spent 2.25 hours a day in front of a computer outside of work, with a standard deviation of 0.75 hours. The survey also found that the population data is most likely normally distributed. a) What portion of adults are in front of a computer for less than 0 hours a day, outside of work? b) Medical professions recommend spending no more than 2 hours in front of a computer each day. What portion of the population is on their computer more than the recommended amount? c)What portion of adults spend between 1 and 5 hours a day in front of a compute reach day, outside of work?
Answer:
a)0.135%
b) 36.944%
c) 95.209%
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 2.25 hours
σ is the population standard deviation = 0.75 hours
a) What portion of adults are in front of a computer for less than 0 hours a day, outside of work?
x < 0 hours
Hence,
z = 0 - 2.25/0.75
= -3
Probability value from Z-Table:
P(x<0) = 0.0013499
Converting to Percentage
= 0.0013499 × 100
= 0.13499%
= 0.135%
b) Medical professions recommend spending no more than 2 hours in front of a computer each day. What portion of the population is on their computer more than the recommended amount?
No more than 2 hours
x ≤ 2 hours
x < 2 hours
Hence,
z = 2 - 2.25/0.75
= -0.33333
Probability value from Z-Table:
P(x≤ 2) = 0.36944
Converting to Percentage
= 0.36944 × 100
= 36.944%
c)What portion of adults spend between 1 and 5 hours a day in front of a compute reach day, outside of work?
For x = 1 hour
z = 1 - 2.25/0.75
= -1.66667
P-value from Z-Table:
P(x= 1) = 0.04779
z = 5 - 2.25/0.75
= 3.66667
P-value from Z-Table:
P(x = 5) = 0.99988
Hence,
0.99988 - 0.04779
= 0.95209
Converting to Percentage
= 0.95209 × 100
= 95.209%
