slope form of the equation for this line?
O y- 13 = 5(%- 2)
O y + 13 = 5(x + 2)
O y- 2 = 5(x- 13)

A bran with the dimensions shown is to be painted. One gallon of pain covers 400 square feet. 23 gallons of  pain is need for the one coat of the barn. Option B is correct.

Given that,

A bran with the dimensions shown is to be painted.

One gallon of pain covers 400 square feet.

We have to find how much gallon of paint for one coat on the entire external of the bran, including the roof.

So,

We can see in the picture

1 side of the barn is rectangle with length and breath that is 24 feet and 60 feet.

1 side of the barn is square with side 40 feet.

The front upper side has a triangle with height 21 feet.

Now, We find the area of the rectangle.

Area of rectangle is length × breath

=24feet×60 feet  

=1440 square feet

1440 square feet divided by 400 square feet

1440/400=3.6

So, the bran has 2 rectangular sides so 3.6+3.6=7.2

Now, we find the area of square.

Area of square is side × side

=40 feet ×40 feet

=1600 square feet

1600 square feet divided by 400 square feet.

1600/400=4

So, the barn has 2 square side so 4+4=8

Now, we find the area of triangle.

Area of triangle is 1/2×breath ×height.

=1/2×40 feet×21 feet

=1/2×840 square feet

=420 square feet

420 square feet divided by 400 square feet.

420/400=1.05

So, the barn has 2 triangles back and front so 1.05+1.05=2.1

Now, we find the area of roof

Roof is in rectangle with breath 60 feet and height 21 feet

Area of rectangle is length × breath

=60 feet ×21 feet

=1260 square feet

1260 square feet divided by 400 square feet.

1260/400=3.15

So, the barn has 2 rectangle roof so 3.15+3.15=6.3

Now, Adding all the areas we get

=7.2+8+2.1+6.3

=23.6

Therefore, approximately 23 gallons of  pain is need for the one coat of the barn. Option B is correct.

Answer:

180° = pi radians

Step-by-step explanation:

360° = 2pi radians

90° = pi/2 radians

see image

180° is pi radians.

pi radians is equivalent to 180 degrees, option B is correct.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The radian equivalent of 180° is pi radians.

This is because a full circle is 360°, which is equivalent to 2 pi radians. Therefore, half of a circle or an angle of 180° is equivalent to half of 2 pi radians, which is pi radians.

Hence,  pi radians is equivalent to 180 degrees, option B is correct.

The mean of the set is less than the median. Option B is correct.

Given that,
Norberto received the following scores on his last five spelling tests 93, 66, 78, 85, and 98.

The mean of the values is the ratio of the total sum of values to the number of values.

Here,
Marks scored by Norberto in 5 spelling tests are 93, 66, 78, 85, and 98.
Mean of marks score = total marks scored / total spelling test
Mean of marks score = (93 + 66 + 78 + 85 + 98) / 5
Mean of marks score = 420 / 5 = 84

Now,
In order to get the median,
Arrange the marks in ascending order,
66, 78, 85, 93, 98
n = 5
median = (n + 1) / 2th term  
             = (5 + 1) / 2th term
             =  6 / 2 = 3 th term
Median = 85
Here, 85 > 84 implies the median is more than the mean.

Thus, the mean of the set is less than the median. Option B is correct.

Answer:

135 degrees.

Step-by-step explanation:

Circumference of the circle

So 3pi = (3pi / 8pi) * 360

= 3/8 * 360

= 135 degrees.

Answer:

7.722[tex]cm^2[/tex]

Step-by-step explanation:

Work out the area of the circle

By the length of the square, you know the diameter of the circle is 12 cm so the radius is 6cm. Then you can calculate the area of the circle by doing

[tex]6^{2}[/tex]π =36π [tex]cm^{2}[/tex]

Work out the area of the square

12 x 12 = 144 [tex]cm^{2}[/tex]

So the bit not occupied by the circle will be 144- 36π = 30.888 [tex]cm^2[/tex]

However, the shaded area is just 1/4 of this bit so 30.888 / 4 = 7.722 [tex]cm^2[/tex]

[tex]\frac{1}{3}x=-\frac{18*3}{1*3} +\frac{2}{3}[/tex]

[tex]\frac{1}{3}x=\frac{-54+2}{3}[/tex]

[tex]\frac{1}{3}x=\frac{-52}{3}[/tex]

Use cross multiplication to find the value of x.

[tex]\frac{1x}{3}=\frac{-52}{3}[/tex]

Answer:

Minimum: 189

Maximum: 786

Median: 572

Lower quartile: 275

Upper quartile: 653

Step-by-step explanation:

Listing the numbers in order from least to greatest, we have: 189, 274, 276, 403, 572, 649, 652, 654, 786.

From this, we can see that the smallest (minimum) value is 189, and the largest (maximum) value is 786.

We can find the the median by taking off a number from each side of the number set one by one. When done, we can see that the number in the middle is 572, so that is our median.

To find the upper and lower quartiles, split the number set in half where the median lies and find the median of those two sections.

Q1: 189, 274, 276, 403

274 + 276 = 550

550 ÷ 2 = 275

--------------------------

Q3: 649, 652, 654, 786

652 + 654 = 1306

1306 ÷ 2 = 653

So, the lower quartile range is 275, and the upper quartile range is 653.

Answer:

The answer is x= 6.2 and y= 5.7

Step-by-step explanation:

Let the two numbers be x and y.

1st condition:

x+y= 11.9 --- (1)

2nd condition:

x-y=0.5--- (2)

Solving 1 and 2

x+y= 11.9 --- (1)

x-y=0.5--- (2)                           (here +y and -y  will get cancelled)

_____________

2x= 12.4

x= 12.4/2 = 6.2

∴x= 6.2

Now, put x= 6.2 in equation (1)           ( u can put in eqn 2 also)

6.2+y= 11.9

y= 11.9-6.2= 5.7

∴y= 5.7

To recheck you can put the value of x and y in any of the eqns.  

The LHS will be equal to RHS if the values we got are correct.

By working with fractions, we will see that the amount that Rollie borrowed from his sister is $31.50.

Let's say that Rollie borrowed a quantity x.

The first month, Rollie returns one third of x + $3, so now he owes:

x - x/3 - 3 = (2/3)*x - 3

the second month returns another third of what he owes plus $3, so now he returns:

(1/3)*((2/3)*x - 3) + 3 = (2/9)*x + 2

So no he owes:

(2/3)*x - 3 - (2/9)*x - 2 = (4/9)*x - 5

Finally, on the third month he returns:

(1/3)*((4/9)*x - 5) + 3 = (4/27)*x - 5/3 + 3 = (4/27)*x + 4/3

Now he owes:

(4/9)*x - 5 -  (4/27)*x - 4/3 = (8/27)*x - 19/3

And that is equal to $3, what he owes at the end of the third month, so we need to solve:

(8/27)*x - 19/3 = 3

(8/27)*x = 3 + 19/3 = 28/3

Solving for x, we get:

x = (27/8)*(28/3) = 31.5

So Rollie borrowed $31.5 from his sister.
