Answer: The width of each flag = 12 cm

The average amount of time it takes Sandra to make each flag =  20 minutes.

Step-by-step explanation:

Given: The ratio of the length to the width the official german flag is 5:3.

Let length = 5x, width = 3x

Length of each flag = 20 cm

i.e. [tex]5x=20\Rightarrow\ x=\dfrac{20}{5}=4\text{ cm}[/tex]

Then width of each flag = 3 x 4 = 12 cm

i.e. width of each flag = 12 cm

Total time to make 12 flags = 4 hours

Time taken to make 1 flag = [tex]\dfrac{4}{12}[/tex] hour

Time taken to make 1 flag = [tex]\dfrac{1}{3}[/tex] hour

1 hour = 60 minutes

Time taken to make 1 flag = [tex]\dfrac{1}{3}\times60[/tex] minutes = 20 minutes.

Hence, the average amount of time it takes Sandra to make each flag =  20 minutes.

Answer:

x=3

Step-by-step explanation:

[tex]\frac{x}{9} =\frac{8}{21+x}[/tex]

x²+21x-72=0

(x-3)(x+24)=0

x=3 or x=-24(rejected)

∴x=3

Answer: 5 miles

Step-by-step explanation:

It's a triangle so if you use the pythagorean theorem your equations should look like this. Sqroot of 4^2+3^2 which equals 5. Hope this helps. :)

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

Factors of 24 and 40

24:  1, 2, 3, 4, 6, 8, 12, 24

40:  1, 2, 4, 5, 8, 10, 20, 40

8 comes as the GCF of both

Hey there!

The answers are as follows:

7.)

m∠1 = 85

m∠2 = 95

m∠3 = 85

m∠4 = 85

8.)

m∠1 = 60

m∠2 = 120

m∠3 = 60

m∠4 = 120

9.)

they all equal 90

10.) No. Parallel lines do not cross each other, but these, if extended, would cross. You could use a protractor by measuring corresponding angles, and if they aren't equal, they aren't parallel.

Have a terrifcly amazing day!

Answer:

(3,1)

Step-by-step explanation:

If you plot both of the points on a graph you get another straight line.

When you connect the dots you get 3,1 as the midpoint of the two segments :))

Answer:

-3

Step-by-step explanation:

Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. So, in this equation, the b or y-intercept value is missing. The y-intercept is where the line crosses the y-axis. In this case, the line crosses over at the value of -3. Therefore, the missing value is -3.

Answer:

(1, No, No) (2, No, Yes) (3,  6x^2+10) (4, 2x^2-3) (5,  x^2-x) (6, -2x^4+12x+3)

Answer:

K is the independent value.

Step-by-step explanation:

For K, you can plug in any value, so it is independent, but T will always have to follow the value of K.

(The X axis is always independent, and the Y axis is always dependent.)

If you want me to do the "Complete the sentence", please tell me the options in the comments.

Answer:

t is the independantt variable and K is the dependant variable...

Answer: Inequality form : -19<x>3

interval notation:

(--19,3)

Step-by-step explanation:

Answer:

{x | x < - 35 / 2}

Step-by-step explanation:

-4x / 7 > 10

Multiply both sides by 7

-4x /7 * 7 > 10 * 7

-4x > 70

Divide both sides by - 4

-4x / - 4 > 70 / - 4

x < - 35 / 2 (inequality sign changes)

Step-by-step explanation:

By method of elimination;

- Opposite angles are congruent

Congruent means Equal

This is correct.

- Diagonals are congruent

This is incorrect.

- Diagonals bisect each angle.

This is correct.

- Diagonals are perpendicular.

This is correct.

- Opposite sides are parallel.

This is correct.

Answer:

- Opposite angles are congruent

- Diagonals bisect each angle.

- Diagonals are perpendicular.

- Opposite sides are parallel

Answer:

160000

Step-by-step explanation:

Let the cost price = x

At the end of the first price, it loses ten percent = 0.9x

At the end of the second year, it loses an extra ten = 0.9(0.9x)= 0.81x

0.81x=129600

x=160000

Answer:

86.8 m long

Step-by-step explanation:

A pole that is 2.5 m tall casts a shadow that is 1.34 m long. At the same time, a nearby building casts a shadow that is 46.5 m long. How tall is the building? Round to the nearest meter

We solve the above question using the Proportion formula:

Height of the pole/Shadow of the pole = Height of the building /Shadow of the building

Height of the pole = 2.5m

Shadow of the pole = 1.34 m

Height of the building = x

Shadow of the building = 46.5m

Hence:

2.5m/1.34m = x/46.5m

Cross Multiply

1.34m × x = 2.5m × 46.5m

x = 2.5m × 46.5m/1.34m

x = 86.753731343m

Approximately , The height of the building = 86.8 m
