C is the answer, as wind turbines are more expensive

Answer: 112 feet

Step-by-step explanation:

The perimeter of the woods is 26 miles if each grid represents one mile in the figure.

It is defined as the space occupied by the rectangle which is planner 2-dimensional geometry.

The formula for finding the area of a rectangle is given by:

Area of rectangle = length × width

We know the perimeter of the rectangle = 2(length + width)

As we can see closely in the figure the perimeter of the wood is actually a perimeter of a rectangle if we shift vertical and horizontal lines to make it a complete rectangle.

Let's suppose each grid is expressing one mile.

So the length of the rectangle = 9 miles

The width of the rectangle = 4 miles

The perimeter of the woods  = 2(9+4) = 26 miles

Thus, the perimeter of the woods is 26 miles if each grid represents one mile in the figure.

Answer:

1 - 60

2 - 120

3 - 60

4 - 120

5 - 60

6 - 120

7 - 60

8 - 120

Step-by-step explanation:

Via supplementary angles, you can conclude that angle 5 is 60. Because of vertical angles, angle 8 is 120 and angle 7 is 60. Because of alternate exterior angles, angle 1 is congruent to angle 7 and angle 2 is congruent to angle 8, meaning angle 1 is 60 and angle 2 is 120. Because of vertical angles, angle 3 is 60 and angle 4 is 120.

Answer:

17.51

Step-by-step explanation:

this is a right triangle, so sohcahtoa applies

we want x

relative to the angle, x is opposite of it and 25 is adjacent to it (the hypotenuse is the other side)

the formula that combines opposite and adjacent is tan

tanθ = opposite/adjacent

tan(35°) = x/25

multiply both sides by 25 to isolate x

tan(35°) * 25 = x

x ≈ 17.51

Answer:

Step-by-step explanation:

x 1= 3 x 2=−4

Answer:

Account A: Decreasing at 8 % per year

Account B: Decreasing at 10.00 % per year

Account B shows the greater percentage change

Step-by-step explanation:

Part A: Percent change from exponential formula

f(x) = 9628(0.92)ˣ

The general formula for an exponential function is

y = ab^x, where

b = the base of the exponential function.

if b < 1, we have an exponential decay function.

ƒ(x) decreases as x increases.

Account A is decreasing each year.

We can rewrite the formula for an exponential decay function as:

y = a(1 – b)ˣ, where

1 – b = the decay factor

b = the percent change in decimal form

If we compare the two formulas, we find

0.92 = 1 - b

b = 1 - 0.92 = 0.08 = 8 %

The account is decreasing at an annual rate of 8 %.The account is decreasing at an annual rate of 10.00 %.

Account B recorded a greater percentage change in the amount of money over the previous year.

Answer:

35 cm^2

Step-by-step explanation:

First find the area of a square by multiplying its side lengths together: 5 * 5 = 25 cm^2.

Now find the area of the triangle by multiplying the base by the height and dividing by 2: 4 * 5 / 2 = 10 cm^2.

Therefore the total area of the figure is 25 + 10 = 35 cm^2.

Answer:

A.  How many vehicles do Boston residents have per household?

Step-by-step explanation:

A statistical question is that question, which is answered by collecting variable data. For example - “How old are the students in your neighborhood?”

So, here the question that is not statistical is How many vehicles do Boston residents have per household? As its answer can be 1 or 2 at maximum.

Whereas;

B.  How much money do Boston residents spend on transportation every day? This is statistical as you need to conduct survey for this to collect data.

C.  How many Boston residents use public transportation?  This also needs survey to collect data and data will be variable.

D.  How many times per month do Boston residents use public transportation?  This is also statistical as you have to gather data from many people.

E.  How long does it take for Boston residents to travel to work? This is also statistical as everyone will have a variable answer depending on the distance they travel.

Answer:

1/16

Step-by-step explanation:

In the starting, Corrine had 1/4 gallon of blackberries. Now, she poured the berries equally into 4 containers. Therefore, the amount of berries in each container is:1/4 : 4=1/16​

Thus, each container has 1/16 of a gallon of blackberries.

Answer:

1/16 th of a gallon in each container.

Step-by-step explanation:

That would be 1/4 divided by 4.

1/4 / 4

= 1/4 * 1/4

= 1/16.

Answer:

2.90 % rate

Step-by-step explanation:

Simple intrest (si) = $1219

Principal (p) = $4206

time (t) = 10yrs

rate (r) = ?

Now using formula,

r = ix100/p×t

r = 1219×100/4206×10

r = 2.90 ( in calculator it will show 2.898 if the third digit is more than 5 after the decimal in the second number 1 is added so it will be 2.90)

Answer:

5 meters per second.

Step-by-step explanation:

There are 60 seconds in 1 minute:

1 minute 20 seconds = 60 seconds + 20 seconds = 80 seconds.

Divide the amount of meters swam (400) with the total amount of seconds used (80) to get the average meters per second:

(400 meters)/(80 seconds) = 5 meters/second.

5 is your answer.

~

Answer:

5 MPS

Step-by-step explanation:

If Ciera can swin 400 meters in 1 minute and 20 seconds,

400 meters = 1 minute 20 seconds (1 1/3 minutes).

Divide both sides by 1 1/3.

400/ 1 1/3 = 300

Since it asks in seconds, divide by 60.

300/60=5

Area = 224 square yards

Step-by-step explanation:

Width = 3.5 squares

Multiply to yards (x4)

Width = 14 square yards

Length = 16 square yards

Area = Width*Length

Area = 14 * 16

Area = 224 square yards

Answer:

Probably 128 km/h, but maybe 98.5 km/h. See below.

Step-by-step explanation:

What does "at the same time" mean?

If it means that he covered the 240 km in the same time as he convered the 80 km, then this is how you solve it:

80 km in 1.25 hour

240 km in 1.25 hour

Total distance: 80 km + 240 km = 320 km

Total time: 1.25 hour + 1.25 hour = 2.5 hour

average speed = (total distance)/(total time) = 320 km / 2.5 hour = 128 km/h

If it means he covered the 240 km in the same time he covered the 80 km plus the rest, then this is how you solve it:

80 km in 1.25 hour

240 km in 1.25 hour + 45 min = 240 km in 1.25 houir + 0.75 hour = 240 km in 2 hour

Total distance: 80 km + 240 km = 320 km

Total time: 1.25 hour + 2 hour = 3.25 hour

average speed = (total distance)/(total time) = 320 km / 3.25 hour = 98.5 km/h

Answer:

61 cm or 0.61 m

Step-by-step explanation:

1. One meter is 100 cm, so you multiply 1.7 meters by 100 to get 170 cm.

2. Now that they are in the same units, to get their difference in height, you subtract Sheila's height from her son's (170 - 109) and get 61 cm.

3. Convert it back to meters by dividing by 100 and you get their difference in height in meters, 0.61 m.

Answer:

0.61

Step-by-step explanation:

One cenimeter is equivalent to 0.01 meter.

109cm • 0.01 = 1.09m

1.7m - 1.09m = 0.61m

Sheila is 0.61m taller than her son
