Answer: the length of the ladder is 40 meters.

Step-by-step explanation:

The ladder forms a right angle triangle with the wall and the ground.

The length of the ladder represents the hypotenuse of the right angle triangle.

The distance of the base of the ladder due west of the burning building represents the adjacent side of the right angle triangle.

To determine the length of the ladder, h, we would apply the cosine trigonometric ratio. It is expressed as

Cos θ = adjacent side/hypotenuse. Therefore,

Cos 51 = 25/h

h = 25/Cos 51 = 25/0.6293

h = 40 meters to the nearest meter.

IgorLugansk [536]

Answer:

y=0.2x+29

Step-by-step explanation:

Given that:

y is the total monthly of the A Fee and Fee plan.

x is the number of monthly minutes used.

  • If a customer uses 290 minutes, the monthly cost will be $87, we have the pair (290, 87)
  • If the customer uses 980 minutes, the monthly cost will be $225, this is the coordinate pair (980, 225).

We want to obtain an equation in the form: y=mx+b

First, let us determine the slope, m

Given points (290, 87) and (980, 225):

<u>Slope</u>

m=\dfrac{225-87}{980-290} =\dfrac{138}{690}=0.2

Next, we determine the y-intercept, b.

Substituting the pair (290, 87) and m=0.2 in y=mx+b, we obtain

87=0.2(290)+b

b=87-0.2(290)=29

Therefore, our equation in the form y=mx+b is:

y=0.2x+29

Kyle buys a turtle tank for Tiny, his pet turtle. The tank is 16 inches tall. The base
lions [1.4K]

The volume of the Tiny's tank will be equal to V=7760 cubic inches.

<h3>What is volume?</h3>

Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width and height of the cube and for the cone it will be radius and height.

It is given that:-

The tank is 16 inches tall.

The area of the tank is 485 square inches

So the volume of the tank will be:-

V= πr²h

V=Area x h

V= 485 x 16

V= 7760 cubic inches

Therefore the volume of the Tiny's tank will be equal to V=7760 cubic inches.

Can someone help it’s due in 40mins!!
Lorico [155]

Answer:

Step-by-step explanation:

\frac{8}{32}  =  \frac{4}{16}  =  \frac{2}{8}  =  \frac{1}{4}

\frac{27}{54}  =  \frac{9 }{18}  =  \frac{3}{6}  =  \frac{1}{2}

\frac{36}{24}  =  \frac{18}{12}  =  \frac{9}{6}  =  \frac{3}{2}

\frac{30}{60}  =  \frac{15}{30}  =  \frac{5}{10}  =  \frac{1}{2}
