A scale factor is usually a decimal which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x.

Answer:

2/5

Step-by-step explanation:

Since it's from a big square to a smaller square, the smaller number will be at the top. Also, use the same side to find the scale factor, but since this is a square and all sides of a square are equal, it doesn't matter but in other shapes it does so practice i guess:

Left side of big square: 5

Left side of small square: 2

So scale is 2/5

To confirm:

5 · 2/5 = 10/5 = 2, we're right

a factory manufactures a metal piece in 32 minutes now technology allowed the factory to cut the time by 8% then another Improve

aliya0001 [1]

Answer:

28 minutes

Step-by-step explanation:

First you have to find what 8% off of 32 is

If you take away 8% of 100% you have 92%

In order to find 92% of 32 you must divide 92 by 100 and multiply it by 32

.92 x 32 = 29.44

Then you have to take off another 5%

Of you take 5% off of 100% you have 95%

.95 x 29.44 =27.97

Then round to the nearest minute

28 minutes

H varies directly to the cube of c. When H = 40, C = 2. (a) Express H in terms of c.

Alecsey [184]

Answer:

H in terms of c is H = 5c³.

Step-by-step explanation:

Given that:

H = 40 and c = 2

H varies directly to the cube of c.

Which means that,

H ∝ c³

Let,

k be the proportionality constant.

H = kc³

Putting H=40 and c=2

$40=k(2)^3\\40=k(8)\\40=8k\\8k=40$

Dividing both sides by 8,

$\frac{8k}{8}=\frac{40}{8}\\k=5$

Now,

H in terms of c.

H = 5c³

Hence,

H in terms of c is H = 5c³.

Got this question for homework. I don't know how to solve it, got a few more like this so I would like to see how to do it more

elena55 [62]

Part 1

Subtracting 5 from both sides yields

$x=f(x)-5$

Part 2

When the output, f(x) is 2, we can substitute that in to obtain

$x=2-5=-3$

I am struggling with triangles missing angles with the formula if you could explain your answer step by step that would be great

Alborosie

Answer:

See below.

Step-by-step explanation:

The 3 angles of all triangles add up to 180 degrees.

An isosceles triangle has 2 of its angles equal.

So if one of the angles is 130 degrees then there cant be another one of 130 degrees as that would make 260 degrees.

So the other 2 angles are equal and their measure is (180 - 130) / 2

= 50 / 2

= 25 degrees.

The 2 equal angles are both 25 degrees.

B. Calculate the distance Kinsey jogs if she jogs'mile each day for 9 days.

yuradex [85]

Answer:

9x miles

Step-by-step explanation:

Distance covered per day = x mile per day

Number of days = 9days

Unknown:

Distance covered for 9 days = ?

Solution:

This is a simple problem.

Since Kinsey covered a distance of x mile/day, in 9 days:

x mile is covered in 1 day;

1 day, Kinsey covers x mile

9 days, she will cover 9 x (x) miles = 9x miles
