If 13 - 3z= 15z +4, z = ?

Answers

Answer 1

Answer:

z = 1/2 or 0.5

Step-by-step explanation:

13 - 3z = 15z + 4

   +3z    +3z

  13 = 18z + 4

  -4            -4  

      9 = 18z

      z = 9/18

      z = 1/2 or 0.5

Answer:

The value of x is 15 cm

Step-by-step explanation:

#(d)

In Δ BDC

∵ ∠D is a right angle

∴ BC is the hypotenuse

∴ BD and DC are the legs of the right angle

→ By using Pythagoras Theorem

(BC)² = (BD)² + (DC)²

∵ BD = 10 cm

∵ DC = 2√11 cm

→ Substitute them in the equation above

∴ (BC)² = (10)² +(2√11)² = 100 + 44 = 144

→ Take √  for both sides

BC = 12 cm

In Δ ABC

∵ ∠B is a right angle

∴ AC is the hypotenuse

∴ AB and BC are the legs of the right angle

→ By using Pythagoras Theorem

(AC)² = (AB)² + (BC)²

∵ AB = 9 cm

∵ BC = 12 cm

AC = x

→ Substitute them in the equation above

∴ x² = (9)² +(12)² = 81 + 144 = 225

→ Take √  for both sides

x = 15 cm

The value of x is 15 cm

The coordinates of point A on a grld are (-3,-2), Point A is reflected across the y-axls to obtain point B. The coordinates of point B are
-2).

Answers

Answer:

The coordinates of the image of B(-3, -2) is B'(3, -2).

Step-by-step explanation:

We know that when a point (x, y) is reflected across the y-axis, the y-coordinate remains the same, and then the x-coordinate becomes negative.

i.e.

Thus, the image of P(x, y) is P' (-x, y).

Given the point

B(-3, -2)

Hence, the image of B(-3, -2):

(-x, y) → (-(-3), -2) = (3, -2)

Therefore, the coordinates of the image of B(-3, -2) is B'(3, -2).

Answer:

y = 4x -13

y = 4x -13Step-by-step explanation:

y= mx + b

y= mx + b m is the Slope

y= mx + b m is the Slopem = 4

y= mx + b m is the Slopem = 4Now just plug in the coordinates (5, 7) from above to solve for b

y= mx + b m is the Slopem = 4Now just plug in the coordinates (5, 7) from above to solve for b7 = 4(5) + b

y= mx + b m is the Slopem = 4Now just plug in the coordinates (5, 7) from above to solve for b7 = 4(5) + b7 = 20 + b

y= mx + b m is the Slopem = 4Now just plug in the coordinates (5, 7) from above to solve for b7 = 4(5) + b7 = 20 + bSubtract 20 from both sides of the equation

y= mx + b m is the Slopem = 4Now just plug in the coordinates (5, 7) from above to solve for b7 = 4(5) + b7 = 20 + bSubtract 20 from both sides of the equation7- 20 = b

y= mx + b m is the Slopem = 4Now just plug in the coordinates (5, 7) from above to solve for b7 = 4(5) + b7 = 20 + bSubtract 20 from both sides of the equation7- 20 = b-13 = b

y= mx + b m is the Slopem = 4Now just plug in the coordinates (5, 7) from above to solve for b7 = 4(5) + b7 = 20 + bSubtract 20 from both sides of the equation7- 20 = b-13 = bThe line in slope intercept form is

y= mx + b m is the Slopem = 4Now just plug in the coordinates (5, 7) from above to solve for b7 = 4(5) + b7 = 20 + bSubtract 20 from both sides of the equation7- 20 = b-13 = bThe line in slope intercept form isy = 4x -13

Calculate the area of both the skating area and the spectator area.

Area = L * W

L = 4x

W = 4x

Area = 4x * 4x

Area = 16x^2

Step Two.

Find the radius of the semicircle. R = radius

From the diagram

R = The full length - the length given in the red shaded area.

R = 4x - 2x

R = 2x

Step Three

Find the area of the semicircle.

Area of a full circle = pi R^2

Area of a 1/2 circle = [tex]\frac{\pi *(2x)^2}{2}[/tex]

Area of a 1/2 circle = [tex]\frac{\pi *4*x^2}{2}[/tex]

Area of a 1/2 circle = [tex]\frac{\pi *2*x^2}{}[/tex]

Notice that the 2 in the denominator cancels in part with the 4 in the numerator.

Step Four

Find the area of the shaded area

Area of the shaded Area = Whole Area - Area of the Semi Circle.

Area of the shaded Area = 16x² - [tex]\frac{\pi *2*x^2}{}[/tex]

Mr. Brown bought some books at a book sale, including 4 paperback books. 20% of all the books he bought were paperbacks. How many books did Mr. Brown buy in all?​

Answers

Answer:

20 books

Step-by-step explanation:

20% is 1/5 of 100% so the other 4/5 would be 4 times 5 which equals 20 books it total

Answer:

Mr. Brown bought 20 books.

Step-by-step explanation:

20% times 5 would be 100%. Since Mr. Brown bought 4 books, and that was 20% of all the books he bought, you would have to multiply the number of paper back books by 5 to get the answer of 100% of all books he bought, which would be 20. This problem would look like this 20(5) = 4(5), 100% = 20 books.

quentin is filling a glass that holds 1 3/4 cups of water. he is using 1/4 cup measuring cup. how many times will he have to fill the smaller measuring cup to equal 1 3/4 cups?

Answers

Answer: 7 lol

Step-by-step explanation:

The number of times he will have to fill the smaller measuring cup to equal 1 3/4 cups is 7 times.

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Glass holds = 1(3/4) cups of water

One cup holds = 1/4 cup of water

Now,

The number of 1/4 cups needed to fill the 1(3/4) cups of water glass.

1/4 x C = 1(3/4)

C/4 = 7/4

C = 7/4 x 4

C = 7

Thus,

The number of times the smaller cup fills the glass is 7.
