Mathematics
1 answer:
g100num [7]3 years ago
6 0

Answer:

Amy can knit \frac{1}{8} 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:

\frac{4x}{5} = \frac{1}{10}

x = \frac{5}{10*4} = \frac{5}{40} = \frac{1}{8}

Amy can knit \frac{1}{8} of a scarf in 1 hour.

Aleks04 [339]

Answer: maybe 50.9

Step-by-step explanation: we can use the pythagorean theorem A^+B^=C^

36 x36 = 1,296

1,296 + 1,296 = 2,592

square root of 2,592 = 50.911688245431421756860794071549 rounded to 50.9

so your answer maybe 50.9

The measure of central angle xyz is radians. What is the area of the shaded sector? 32 85 96 256.
statuscvo [17]

If the measure of central angle is 3π /4 radians, then the area off the shaded sector is 96π square units

The radius of the circle = 16 units

The central angle of the shaded region = 3π /4 radians

The area of the sector = (θ/ 360) × πr^2

Where θ is the central angle of the sector

r is the radius of the sector

Substitute the values in the equation

The area of the sector = ((3π /4) /360) × π × 16^2

Convert the radians to the degrees

= (135/360) × 256π

Multiply the terms

= 96π square units

Hence, the area of the shaded sector is  96π square units

The complete question is

The measure of central angle XYZ is 3 pie / 4 radians. What is the area of the shaded sector?

Write an equation in slope-intercept form for the line with slope 8 and y-intercept -8.​
Fofino [41]

Answer:

y = 8x - 8

Step-by-step explanation:

y = mx + b is slope-intercept form

m - slope

b - y-intercept

so if you plug in 8 for m and -8 for b you'll get

y = 8(m)x - 8(b)

Hope this helps!!
