Answer:

10. 1/9

11. 1 1/6

12. 1/8

Step-by-step explanation:

10.

He spent 2/3 of 1/6 of the day.

In math, "of" means multiplication, so 2/3 of 1/6 means 2/3 * 1/6.

2/3 * 1/6 = 2/18 = 1/9

He spent 1/9 of the day adding mulch.

11.

He spent 2/3 of 1 3/4 hours.

In math, "of" means multiplication, so 2/3 of 1 3/4 means 2/3 * 1 3/4.

2/3 * 1 3/4 = 2/3 * 7/4 = 14/12 = 7/6 = 1 1/6

He spent 1 1/6 hours working on the project.

12.

She planted 1/6 of 3/4 of the area.

In math, "of" means multiplication, so 1/6 of 3/4 means 1/6 * 3/4.

1/6 * 3/4 = 3/24 = 1/8

She planted carrots in 1/8 of the garden.

Solve for u: u + 16 > 20 or u + 20 < 14

Hatshy [7]

u+16> 20 or u+20 < 14

first u +16>20

subtract 16 from each side

u > 4

u+20 < 14

subtract 20 from each side

u < -6

so.....

u < -6 or u > 4

A right cone with a radius of 4 inches and a square pyramid both have a slant height of 5 inches. Both solids have the same surf

Masteriza [31]

The surface area of the cone is given by:
SA=πrl
Thus the surface area of the cone will be:
SA=π×4×5
SA=20π=63.932

Surface area of the pyramid is given by:
SA=1/2×4×(b×l)
thus the base length will be:
63.932=10l
thus
l=6.3932 in

In the given question, the two sides of the given triangles are parallel, so the the two corresponding angles of the Triangles are equal to one another.

Therefore, the Triangles are similar by AA similarity criteria ~

And since they are similar, the ratio of sides of one Triangle will be equal to ratio of corresponding sides of the other Triangle.

that is ~

$\sf \dfrac{5}{7} = \dfrac{5 + 6}{y}$

$\sf y = 11 \times \dfrac{7}{5}$

$\sf y = \dfrac{77}{5}$

$\sf y = 15.4$

Hence, value of l = 15.4 units ~
