Make x the subject of the formula y= 2x +5
Kryger [21]

Answer:

x= (y-5)/2

Step-by-step explanation:

Isolate the x variable.

y= 2x +5

Subtract 5 from both sides.

y-5=2x

Divide both sides by 2.

(y-5)/2= x

Quadrilateral ABCD is inscribed in this circle. What is the measure of ∠A ? Enter your answer in the box. ° A quadrilateral insc
Lubov Fominskaja [6]
Answer: The measure of angle A is 59 degrees.

When you have a quadrilateral inscribed in a circle the opposite sides are always supplementary (add to 180). Given the order of the vertices of our quadrilateral, we know that A and C are opposite.

Therefore, we can write and solve the following equation.
A + C = 180
A + 121 = 180
A = 59 degrees

look at the explanation

Step-by-step explanation:

A cylindrical container has a height of 14 inches and radius of 3.2 inches. It is filled with pasta, but there is 1.5 inches of space left at the top. How many cubic inches of pasta are in the container?

1. Given

h = 14 in

r = 3.2 in

space = 1.5

V pasta = πr² (h - space)

V pasta = π(3.2)² (14 - 1.5)

V pasta = 402.12 in³

Izzie has a muffin tin that holds 12 muffin cups. Each cup is cylindrical with a diameter of 3 inches and a height of 3.5 inches. Izzie has 544.28 cubic inches of batter. How many muffins can she bake?

2. Given

h = 3.5 in

d = 3 in

V batter = 544.28

V muffin = πd²h/4

V muffin = π(3)²(3.5)/4

V muffin = 24.74 in³

# of muffin = V batter/ V muffin

# of muffin = 544.28/ 24.74 = 22

so she can bake 22 muffins

A popsicle tray has 6 cone-shaped popsicle molds. Each popsicle mold has a diameter of 5.4 cm and a height of 12.9 cm. How many cubic centimeters will one tray hold?

3. Given

d = 5.4 cm

h = 12.9 cm

6 cone-shaped popsicles per tray

V popsicle = πd²h/12

V popsicle = π(5.4)²(12.9)/12

V popsicle = 98.48cm³

V popsicle per tray = (98.48cm³) (6)

V popsicle per tray = 590.88cm³

A cone has a volume of 1,230.88 units³ and a diameter of 14 units. How many units is the height of the cone? Use 3.14 for pi.

4. Given

V cone = 1,230.88 units³

d = 14 units

V cone = πd²h/12

h = 12V cone/πd²

h = 12(1230.88)/ (3.14) (14)²

h = 24 units

A cylinder has a volume of 7,598.8 units³ and a height of 5 units. How many units is the diameter of the cylinder? Use 3.14 for pi.

5. Given

V cylinder = 7,598.8 units³

h = 5 units

V cylinder = πd²h/4

d = √4V cylinder/πh

d = √4(7598.8)/3.14(5) = √1936

d = 44 units

Jana and Haiya are each filing a witch's hat in the shape of a cone with candy. Each hat has a radius of 3.4 inches and height of 12.5 inches. How many cubic inches of candy will both hats hold?

6. Given

r = 3.4 in

h = 12.5 in

V hat = πr²h/3

V hat = π(3.4)²(12.5)/3

V hat = 151.32 in³

V two-hats = 2(151.32 in³ )

V two-hats = 302.64 in³


George has 1 ½ containers of toothpaste in the shape of a cylinder. Each container has a diameter of 4 cm and a height of 15 cm. How many cubic centimeters of toothpaste does he have?

7. Given

d = 4 cm

h = 15 cm

V container = πd²h/4

V container = π(4)²(15)/4

V container = 188.496 cm³

V toothpaste = 1.5V container = 1.5(188.496 cm³)

V toothpaste = 282.74 cm³

A cone has a diameter of 16 units and a height of 11 units. How many cubic units is the volume of the cone?

8. Given

d = 16 units

h = 11 units

V cone = πd²h/12

V cone = π(16)²(11)/12

V cone = 737.23 units³
