Answer:

Amy can knit [tex]\frac{1}{8}[/tex] of a scarf in 1 hour.

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

We have that:

1/10 of a scarf - 4/5 of an hour

x of a scarf - 1 hours.

Applying cross multiplication:

[tex]\frac{4x}{5} = \frac{1}{10}[/tex]

[tex]x = \frac{5}{10*4} = \frac{5}{40} = \frac{1}{8}[/tex]

Amy can knit [tex]\frac{1}{8}[/tex] of a scarf in 1 hour.

Answer:

by SSS axiom

hope it helps.

Answer:

Step-by-step explanation:

Yes

the two sides that are marked make 2/3 of the sides needed for SSS

The line shared by both triangles make the third side.

Answer: SSS

Answer:

192 miles

Step-by-step explanation:

This is a right triangle problem

One leg of the triangle is

50 * 3 = 150

The other leg is

40 * 3 = 120

the distance is the hypotenuse

c^2 = 150^2 + 120^2

c^2 = 22500 + 14400

c^2 = 36900

Take the square root of both sides

c = 192.093727123

c ≈ 192 miles

Answer:

30 miles apart

Step-by-step explanation:

Im not sure if this is the corect answer to this but this is what i think what i did was get 50 x 3 and 40 x 3 since they starded at the same times and finished after 3 hours so multiply your numbers by 3 so...

50 x 3=150

40 x 3=120

150-120=30 miles apart

Answer:

4

Step-by-step explanation:

The angle between the two tangents drawn from an external point to a circle and the angle subtended by the line segment joining the points of the contact at the Centre are supplymentary,

So,

15.) let the unknown angle be x

=》x + 55° = 180°

=》x = 180° - 55°

=》

[tex] \boxed{x = 125°}[/tex]

16. let the unknown angle be n

=》n + 80° = 180°

=》n = 180° - 80°

=》

[tex] \boxed{n = 100°}[/tex]

9514 1404 393

Answer:

  15)  125°

  16  100°

Step-by-step explanation:

The short arc where two tangents intersect a circle, and the angle where the tangents meet are supplementary.

__

15) ? = 180° -55° = 125°

16) ? = 180° - 80° = 100°

_____

Additional comment

The quadrilateral formed by the tangents and the radii to the points of tangency has a total interior angle measure of 360°. The angles where the radii meet the tangents are 90°, so the sum of the external angle and the central angle is 360° -90° -90° = 180°. That is, the external angle and the central angle are supplementary.

Answer:

-13-4i

Step-by-step explanation:

Answer:

The answer is C.

Step-by-step explanation:

angle 5 and 4 makes a line which is 180 and since angle 5 equals 57 , 180-57=123.

By using a z-value less than -1, we can find a price that is significantly lower than the average cost, and therefore more likely to attract customers.

Option B is the correct answer.

Standard deviation is a measure of the amount of variability or spread in a set of data.

It is calculated as the square root of the variance and is often denoted by the symbol σ (sigma) for a population and s for a sample.

We have,

The z-value formula is used to determine the number of standard deviations a data point is from the mean.

To determine the lower price of appetizers, we want to find a price that is significantly lower than the average cost.

Since the new restaurant wants to offer appetizers for a much lower price, we should use a z-value that is less than -1, which indicates a price that is more than one standard deviation below the mean.

Recall that the z-value formula is:

z = (x - μ) / σ

where x is the value of interest, μ is the mean, and σ is the standard deviation.

Thus,

By using a z-value less than -1, we can find a price that is significantly lower than the average cost, and therefore more likely to attract customers.

Answer: what are you supposed to find out?

Step-by-step explanation:

Answer:

lateral surface area of the cone = 829.0ft²

Hence the total surface area is 1,208.9ft²

Step-by-step explanation:

lateral surface area of the cone = πrl

l is the slant side = 24ft

r is the radius = 11ft

lateral surface area of the cone = π(11)(24)

lateral surface area of the cone = 3.14 * 264

lateral surface area of the cone = 828.96ft²

lateral surface area of the cone = 829.0ft²

Total surface area = πr(r+l)

r is the radius = 11ft

l is the slant side = 24ft

Total surface area = π(11)(11+24)

Total surface area = π(11)(35)

Total surface area = 3.14 * 385

Total surface area = 1,208.9ft²

Hence the total surface area is 1,208.9ft²

Answer:

1. 21, 22

2.29,30

Step-by-step explanation:

1. m+4>24

subtract both sides by 4

m>20

Two values that are greater than 20 are 21 and 22.

2. 7<x/4

multiply both sides by 4

28<x

Two values that are greater than 28 are 29 and 30.

Answer:

both 125° and the 5x+30 are congruent to eachother. therefore you can go

5x+30=125

subtract 30 from both sides.

5x=95

then divide both sides by 5
