What is area of this

nata0808 [166]

Answer:

A = 20.5 sq units

Step-by-step explanation:

you have the height of 5 but need to figure out the base

we can use the Pythagorean Theorem two times to find it

1) a² + 5² = 7²

a² = 49-25

a = $\sqrt{24}$ = $\sqrt{4}$ · $\sqrt{6}$ = 2 $\sqrt{6}$

2) b² + 5² = 6²

b² = 36-25

b = $\sqrt{11}$

Base = 2 $\sqrt{6}$ + $\sqrt{11}$

A = 1/2 x 5· (2 $\sqrt{6}$ + $\sqrt{11}$ )

A = 2.5 · (2 $\sqrt{6}$ + $\sqrt{11}$ )

A = 2.5(8.2)

A = 20.5

Please help with this arc equation.

boyakko [2]

Answer:

Part 1) $arc\ AB=49^o$

Part 2) $arc\ ABC=204^o$

Part 3) $arc\ BAC=156^o$

Part 4) $arc\ ACB=311^o$

Step-by-step explanation:

Part 1) Find the measure of arc AB

we know that

$arc\ AB=m\angle AOB$ ----> by central angle

we have

$m\angle AOB=49^o$

therefore

$arc\ AB=49^o$

Part 2) Find the measure of arc ABC

we know that

The central angle of complete circle is equal to 360 degrees

$arc\ ABC=360^o-107^o-49^o=204^o$

Part 3) Find the measure of arc BAC

we know that

$arc\ BAC=arc\ BA+arc\ AC$ ----> by angle addition postulate

we have

$arc\ BA=49^o$ ---> by central angle

$arc\ AC=107^o$ ---> by central angle

$arc\ BAC=49^o+107^o=156^o$

Part 4) Find the measure of arc ACB

we know that

The central angle of complete circle is equal to 360 degrees

$arc\ ACB=360^o-arc\ AB$

substitute

$arc\ ACB=360^o-49^o=311^o$

The inside diameter of a randomly selected piston ring is a normally distributed random variable with mean 12 cm and standard de

victus00 [196]

Answer:

$x=12.07$

Step-by-step explanation:

From the question we are told that:

Mean $\=x =12cm$

Standard deviation $\sigma=0.04$

Significance level $\alpha=5\%=0.05$

Therefore

Confidence level $95\%=0.95$

From table $P(z$

Generally the equation for Z-score is mathematically given by

$z=\frac{x-\mu}{\sigma}$

$x=z\sigma+\mu$

$x=1.645*0.04+12$

$x=12.07$
