The shape below contains a rectangle and four semi-circles. What is the perimeter of the shape above? What is the area of the sh

Colt1911 [192]

Answer:

Step-by-step explanation:

lets find out the perimeter P

P rectangle= 2*L+2*W=(2*5)+(2*13)=10+26=36

P small semi-circle ( we have 2), where the d=5, r=2.5

Circumference small circle=2*3.14*r= 2*3.14*2.5=15.70

P 2 small circles=15.70*2=31.40

but we need just half of this, because we have semicircles=15.70

Circumference big semicircle (we have 2), where d=13, r=6.5

C big circle=2*3.14*6.5=40.82

Ps big circle=2*40.82=81.64

we need half of this also, so is 40.82

P total figure=36+15.70+40.82=92.52

Area rectangle=5*13=65

Area small circle, basically the 2 semicircle = 1 circle

Area=3.14*r^2=3.14*2.5^2=19.63

Area big circle=3.14*6.5^2=132.73

Area total figure=65+19.63+132.73=217.36

Anit [1.1K]

Answer:

Each piece of ribbon lengths 2.55 feet.

Step-by-step explanation:

A 30-foot piece of ribbon that Elena has cut for a craft project. Then she cuts off 7 feet from this.

So, the remaining length of the ribbon for the craft project will be (30 - 7) = 23 feet.

Now, then she cuts the remaining piece into 9 equal lengths of feet each.

Hence, each piece of ribbon lengths $\frac{23}{9} = 2.55$ feet. (Answer)

What is .. 30% of .. is 60 ?

juin [17]

So question is 'what is x. 30% of x is 60'

remember that percent means parts out of 100 so therefor
30%=30/100=3/10
so the question is
3/10 of x is 60
'of' in math means multiply
3/10 times x=60
3x/10=60
mulitply both sides by 10 to get rid of fraction
3x=600
divide both sides by 3
x=200

.. is 200

the number is 200

Xavier is driving home. He starts 250 miles from home and his car can travel 28 miles per gallon of gasoline he uses. Xavier sto

Leona [35]

Answer:

For 100 miles he uses 3.571 gallons of gasoline.

In equation form it is y/x*100

Step-by-step explanation:

Unitary Method

He travels 28 miles per gallon of gasoline.

For 1 mile he uses 1/28 gallons

For 100 miles he uses 1/28 * 100= 100/28= 3.571 gallons of gasoline.

Let x be the miles and y be the gallons of gasoline used to travel x miles.

Then for 1 mile the gallons of gasoline used will be y/ x gallons.

For 100 miles the gallons of gasoline used will be y/x *100 gallons.

In equation form it is y/x*100 gallons for 100 miles where x is the number of miles and y is the amount of gallons.
