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.

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

Area: T = 84

Perimeter: p = 51.472

Semiperimeter: s = 25.736

Angle ∠ A = α = 69.146° = 69°8'44″ = 1.207 rad

Angle ∠ B = β = 20.854° = 20°51'16″ = 0.364 rad

Angle ∠ C = γ = 90° = 1.571 rad

Height: ha = 8

Height: hb = 21

Height: hc = 7.476

Median: ma = 13.2

Median: mb = 21.378

∠ C' = γ' = 90° = 1.571 rad

Answer:

y = -5x + 2

Step-by-step explanation:

y = -5x + b

2 = -5(0) + b

2 = 0 + b

b = 2

y = -5x + 2

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%

Answer:

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.

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:

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

Step-by-step explanation:

V = πr²h

π · 25² · 40

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
