Answer:

Step-by-step explanation:

according to tangent property

we get

AM=BM
AN=CN
BK=CK

Given that

AM=6
BK=4

Thus our equation is

$\rm \displaystyle 2AM + 2AN + 2BK = 34$

substitute the given values

$\rm \displaystyle 2.6+ 2AN+ 2.4 = 34$

simplify multiplication:

$\rm \displaystyle 12+ 2AN+ 8 = 34$

simplify addition:

$\rm \displaystyle 2AN+ 20= 34$

cancel 20 from both sides:

$\rm \displaystyle 2AN=14$

divide both sides by 2:

$\rm \displaystyle AN=7$

AN=CN

hence,CN=7

therefore our answer is A

2. The bottom of a ramp is placed 15 feet from the edge of a stage

Firdavs [7]

Answer:

The slope of the ramp is 1.

Step-by-step explanation:

See the diagram attached.

Here, AC = 15 ft. and ED = 5 ft. while AE = 10 ft.

Then, EC = (15 - 10) = 5 ft.

Now, considering the right triangle Δ EDC, if $\theta$ is the inclination of the ramp, then $\tan \theta = \frac{ED}{EC} = \frac{5}{5} = 1$

Hence, $\theta = 45 ^{\circ}$

Therefore, the slope of the ramp is 1. (Answer)

The cost for renting a weed trimmer varies directly with the number of hours used. A weed trimmer rented for 5 hours costs $32.5

wlad13 [49]

Let the cost for renting be y and the number of hours be x
then:
y=kx
where:
k is the constant of proportionality
k=y/x
y=$32.5 when x=5 hours
thus;
k=32.5/5
k=6.5
hence the equation is:
y=6.5x
thus the value of y when x=8 hours will be:
y=6.5(8)=$52
Answer:'

A y = $6.5x, y = $52.00

Each T-shirt sells for $8, and each long-sleeve shirt sells for $11. The swim team collected $310 for the 35 shirts that were so

Nonamiya [84]

Answer:

Number of T shirt sold = 25

Number of long-sleeve shirt sold = 10

Option A is the correct answer.

Step-by-step explanation:

Let the number of T shirt be t and long-sleeve shirt be s.

We have cost of T shirt = 8$ and cost of long-sleeve shirt = 11 $.

Total number of shirts sold = 35

t + s = 35 -----------------------Equation 1

Dollar collected = 310 by selling 35 shirts = 310 $

8 t + 11 s = 310 -----------------------Equation 2

Equation 1 x 8

8 t + 8 s = 8 x 35 = 280 -----------------------Equation 3

Equation 2 - Equation 3

8 t + 11 s - 8 t - 8 s = 310 - 280 = 30

3 s = 30

s = 10

Substituting in equation 1

t + 10 = 35

t = 25

Equations are 8t + 11s = 310 and t + s = 35

Number of T shirt sold = 25

Number of long-sleeve shirt sold = 10

Option A is the correct answer.
