Mathematics
1 answer:
Damm [24]4 years ago
5 0

Answer:

The measure of angle B is 67\°

Step-by-step explanation:

we know that

Applying the law of sines

\frac{a}{sin(A)}=\frac{b}{sin(B)}

we have

a=20\ units

b=32\ units

A=35\°

substitute the given values and solve for B

\frac{20}{sin(35\°)}=\frac{32}{sin(B)}

sin(B)=(32)sin(35\°)/20

B=arcsin((32)sin(35\°)/20)

B=67\°

What is 25% of 400 5% of 20
stiks02 [169]

Hello there!


What is 25% of 400?

\frac{25*400}{100}

= \frac{10,000}{100}

= 100

Thus,

25% of 400 is 100


What is 5% of 20?

Well, we just need to follow the previous steps.

\frac{5*20}{100}

= \frac{100}{100} = 1

Thus,

5% of 20 is 1

A company produces widgets in three factories, A, B and C. Factory A produces 20% of the widgets, factory B produces 45% of the
agasfer [191]

Answer:

1.25% widgets from factory A fail.

Step-by-step explanation:

Probability of widgets that fail = 0.05

Probability of failing widget to belong from factory A = 0.25

Probability of failing widget to belong from factory B = 0.35

Probability of failing widget to belong from factory C = 0.40

Probability of factory A widgets failing = Probability of widgets failing * probability they belonged from factory A

Probability of factory A widgets failing = 0.05 * 0.25 = 0.0125

This probability stated as percentage: 1.25%

What is the slope of the line that passes through the points (-1, 2) and (-4, 3)?
Tpy6a [65]

Answer:

Slope = -⅓

Step-by-step explanation:

The equation for the slope of a straight line is

m = (y₂ - y₁)/(x₂ - x₁)

The line passes through (-1, 2) and (-4, 3).

m = (3 - 2)/[-4 - (-1)]

    = 1/(-4 + 1)

    = -⅓

The slope of the line is -⅓.

The Figure below shows the graph of your line through (-1, 2) and (-4, 3) with a slope of -⅓.
