Answer:

3. The amount of wallpaper for a wall in a bedroom

Step-by-step explanation:

1. The number of towels I can fit in a bathroom cabinet

No, sounds more like volume, since a cabinet has space inside.

2. The amount of ribbon used to decorate from one end of a room to the another

No, sounds like perimeter, since a ribbon would need to cover space in one direction.
3. The amount of wallpaper for a wall in a bedroom

Yes, wallpaper is applied in 2 directions and lays flat on a surface to cover a certain area.

9. Find the length of the arc shown in brown. Leave your answer in terms of 2 (1 point)

Nadusha1986 [10]

The length of the arc is 4π.

Step-by-step explanation:

Given,

Diameter = 24 ft
radius, r = diameter/2
r = 24/2 = 12 ft
central angle, ∅ = 60°

Arc length = ∅/360° (2πr)

⇒ 60°/360° (2π $\times$ 12)

⇒ 24π/6

⇒ 4π

∴ The length of the arc is 4π.

Which of the points given divide the line segment AB in the ratio 2:3?

alexira [117]

Answer: The correct answer is Choice D, (5, 7).

First, we need to identify the slope from A to B.
It will be -5/-5. In other words, to go from A to B, we move down 5 spaces and left 5 spaces.

If we are going to divide the segment, we are not going to move all 5 spaces in each direction.

Since we are looking for a 2:3 ratio, we are only moving 2 out of the total of 5 spaces. It is 2 over 5, because 2 + 3 makes a total of 5.

Therefore, we only move down 2 and left 2 spaces from Point A. That will put us at the point (5, 7).

Write and solve the inequality. 6 times a number plus 22 is greater than 7. Which inequality represents the solutions?

LUCKY_DIMON [66]

answer:

6x + 22 > 7

x > -2.5

step-by-step explanation:

write out the inequality
let "a number" be x

6x + 22 > 7

now solve it

6x + 22 > 7

6x > -15

x > -2.5

Here is a flower made up of yellow hexagons, red trapezoids, and green triangles. How many copies of this flower pattern could y

olganol [36]

Answer:

Part a) You could build 5 copies of the flower pattern

Part b) You would have 40 red trapezoids left over

Step-by-step explanation:

The complete question in the attached figure

Part a)

Let

x -----> the number of yellow hexagons

y ----> the number of red trapezoids

z ----> the number of green triangles

we know that

The flower pattern has the following ratios

$\frac{x}{y}=\frac{6}{2} ---->\frac{x}{y}=3 ----> \text {equation A}$

$\frac{x}{z}=\frac{6}{9} -->\frac{x}{z}=\frac{2}{3} --> \text {equation B}$

$\frac{y}{z}=\frac{2}{9} ------> \text {equation C}$

Find out how many copies of this flower pattern could you build if you had 30 yellow hexagons,50 red trapezoids, and 60 green triangles

1) For x=30

Divide 30 by 6 (remember that in one pattern there are 6 yellow hexagons)

$30/6=5\ copies$

Verify the quantity of y needed and the quantity of z needed

Find the value of y

$\frac{30}{y}=3 ---->y=30/3=10\\$

10 < 50 ----> is ok

Find the value of z

$\frac{30}{z}=\frac{2}{3} ---> z=30*3/2=45$

45<60 --->is ok

2) For y=50

Divide 50 by 2 (remember that in one pattern there are 2 red trapezoids)

$50/2=25\ copies$

Verify the quantity of x needed and the quantity of z needed

Find the value of x

$\frac{x}{50}=3 ---->x=50*3=150$

150 > 30 ----> is not ok

3) For z=60

Divide 60 by 9 (remember that in one pattern there are 9 green triangles)

60/9=6.7 copies

Round down

6 copies -----> 6(9)=54 green triangles

Verify the quantity of x needed and the quantity of y needed

Find the value of x

$\frac{x}{54}=\frac{2}{3} ---> z=54*2/3=36$

36> 30 --->is not ok

therefore

You could build 5 copies of the flower pattern

Part b)

we know that

x:y:z=6:2:9

If you build 5 copies

1) You would use 5*6=30 yellow hexagons and you would have 0 hexagons left over

2) You would use 5*2=10 red trapezoids and you would have (50-10=40) trapezoids left over

3) You would use 5*9=45 green triangles and you would have (60-45=15) triangles left over

therefore

You would have 40 red trapezoids left over
