What is mZCAD? O 80° O 20° O 80° O 100° O 110°

denis23 [38]

Answer:

The angle of CAD is 100°.

Step-by-step explanation:

Given that total angles in a triangle is 180° so you will have to find the angle of CAB :

∠CAB + ∠ACB + ∠ABC = 180°

∠CAB + 80° + 20° = 180°

∠CAB + 100° = 180°

∠CAB = 180° - 100°

∠CAB = 80°

Next, you have to subtract it from 180° because straight line have a degree of 180°

∠CAD = 180° - 80°

∠CAD = 100°

0.73 recurring can be writeen as 11/15

Minchanka [31]

Answer:

yes , see explanation

Step-by-step explanation:

We require 2 equations with the recurring 3 placed after the decimal point.

let x = 0.7333.. ( multiply both sides by 10 and 100 )

10x = 7.333... → (1)

100x = 73.333.... → (2)

Subtract (1) from (2) , eliminating the recurring 3

90x = 66 ( divide both sides by 90 )

x = $\frac{66}{90}$ = $\frac{11}{15}$

A grocery stores studies how long it takes customers to get through the speed check lane. They assume that if it takes more than

Reptile [31]

The probability that a randomly selected customer takes more than 10 minutes will be 8.38%

Explanation

The average or mean $(\mu)$ is 8.56 minutes and standard deviation $(\sigma)$ is 1.04 minutes.

Formula for finding the z-score is: $z= \frac{X-\mu}{\sigma}$

So, the z-score for $X=$ 10 minutes will be.....

$z(X=10)=\frac{10-8.56}{1.04}=\frac{1.44}{1.04}=1.3846... \approx 1.38$

Now, according to the standard normal distribution table, $P(z$ . So.....

$P(X>10)=P(z>1.38)= 1-P(z$

So, the probability that a randomly selected customer takes more than 10 minutes will be 8.38%

A golfer needs to know how tall a tree is to chip a ball over the tree onto the green in a golf match. his caddie knows that he

Inga [223]

The height of the trre will be given by:
tan θ=(opposite)/(adjacent)

θ=52°
Adjacent= distance of the golfer to the tree= 10 ft
opposite = height, h, of the tree
thus
tan 52=h/10
hence solving for h we get:
h=10tan52
h=12.799~12.8 ft
