A Japanese garden has a circular koi pond in the middle that has a radius of 3 feet. A rectangle with length of 16 feet and widt
Mariulka [41]

Answer:

first, find the area of the circle cut.

r= 3 feet

π=3.14

area of a circle= πr²= 3.14×3×3= 28.26 sq.feet

Now, find the area of the rectangle and subtract it by the area of the circle.

area of rectangle = l×b

length of the rectangle= 16 feet

breadth/width of the rectangular garden= 14 feet

area=  16×14= 224 sq. feet

now, area of the garden surrounding the koi pond=  224-28.26

                                                                                     =195.74 sq. feet

Becky has been tracking the population of a town. The population was 5,340 last year and has been increasing by 1.75 times each
Scorpion4ik [409]
<span> the population grows at rate of 1.75
multiply it by this rate every year
As in year 3 it would be 5340(1.75)(1.75)(1.75) the function is 5340(1.75)^x
</span>f(x) = 5340(1.75)^x where 1.75 is the rate of growth 
so D is right answer

Blake is 7 years older than Heather. In 7 years the sum of their ages will be 55. How old is Blake now?
Andreas93 [3]

Answer:

24 years old

Step-by-step explanation:

Let the age of Blake be x and the age of Heather by y then...

x=7+y

7+x+7+y=55

Notice we are adding additional 7s because the question states "in 7 years"

Simplify the second equation...

7+x+7+y=55

14+x+y=55

Subtract 21 from both sides

x+y=41

Solve using substitution (substitute 7+y for x since x = 7+y)

7+y+y=41

Combine like terms

2y+7=41

Subtract 7 from both sides

2y=34

Divide both sides by 2

y=17

x=7+17=24

Blake is 24 years old now

Is a triangle with sides of 9in, 25in, 24in a right triangle
Veronika [31]
Try the case if the triangle was a right triangle.
Then the longest side, 25, would be c or the hypotenuse.
9^2+24^2=25^2
81+576=625
657=625
This is not a true statement so the triangle is not a right triangle.

Hope this helps :)

8+35/w=15<br>a.8<br>b.6<br>c.10<br>d.5​
RoseWind [281]

Answer:

\boxed{ \bold{ \huge{ \bold{w = 5}}}}

Option D is the correct option

Step-by-step explanation:

\sf{8 +  \frac{35}{w}  = 15}

⇒\sf{ \frac{8 \times w + 35}{w}  = 15} { w ÷ 1 = w , So, I wrote 8 × w }

⇒\sf{ \frac{8w + 35}{w}  = 15}

Apply cross product property

⇒\sf{8w + 35 = 15w}

Move 15w to left hand side and change it's sign

Similarly, Move 35 to right hand side and change it's sign

⇒\sf{8w - 15w  =  - 35}

Collect like terms

⇒\sf{ - 7 w =  - 35 }

Divide both sides of the equation by -7

⇒\sf{ \frac{ - 7w}{ - 7}  =  \frac{ - 35}{ - 7} }

Calculate

⇒\sf{w = 5}

Hope I helped!

Best regards!!
