What is the length of the radius, r?

Answers

Answer 1

Answer: The length of the radius would be 18cm long

Answer 2

Answer:

Answer:

18 cm

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = 2πr ← r is the radius

Given

C = 36π, then

2πr = 36π ( divide both sides by 2π )

r = $(36\pi )/(2\pi )$ = 18

What number should be added to the expression to turn it into a perfect square trinomial x^2+2x

Answers

kinda like completing the square
if you have
ax^2+bx+c
a=1 for ease

take b and halve it then square that
then make c= that

x^2+2x+c
a=1 good
b=2
2/2=1
1^2=1
x^2+2x+1
(x+1)^2

the number 1 should be added

Solutions

A Perfect Square Trinomial is the product of two binomials. Both the binomials are same. When you multiply an algebraic expression with two terms to itself, you will get a three-term expression called a perfect square trinomial. A perfect square trinomial is one that factors into two identical factors. The general forms of perfect square trinomial are =

(ax - b)² = (ax)² - 2axb + b² and (ax + b)²= (ax)² + 2axb + b²

Calculations

αx²+βx+c

The variable α = 1 for ease

Take the variable b and half it then square that
to make c = number

x²+2x+c

variable α = 1

variable β = 2

2 ÷ 2=1

1² = 1

x²+2x+1

(x+1)²

In conclusion the number (1) should be added to the expression to turn it into a perfect square trinomial .

A recipe calls for 2 2/4 cups of raisins, but Julie only has a 1/4 cup measuring cup. How many 1/4 cups does Julie need to measure out 2 2/4 cups of raisins?

Answers

to get to cups of raisins you need 8 1/4 cups, and then to get 2/4 you need 2.

So basically you need 10 1/4 cups

10 cups because 1 is split into 4 parts and 4+4=8and 2/4is two times of 1/4 and 2+8=10

HECTOR PLANTED 185 FLOWERS IN 2 DAYS THERE WERE 5 VOLUNTEERS INCLUDING HECTOR WHO EACH PLANTED ABOUT THE SAME NUMBER OF FLOWERS ABOUT HOW MANY FLOWERS DIDTHEY PLANT SHOW YOUR WORK

possible answers:185, 400, 500, 1,000

these are the answers the problem gives me

Answers

Line up 185x5 on the paper as if you were doing any other multiplication problem. 185 on top, 5 on the bottom with the x sign to the left.5 times 5 is 25, drop the five, carry the 2, 5 times 8 is 40, plus the 2 we carried is 42, drop the two, carry the four, 5 times one is five, plus the four is 9. The answer is close to 1,000, so you'd circle the answer 1,000.

Let

x-------->number of flowers that the $5$ volunteers planted in $2$ days

we know that

$x=185*5\n x=(100+80+5)*5\n x=100*5+80*5+5*5\n x=500+400+25\n x=925$

therefore

the answer is

about $1,000$

Can someone help me with number 11 its increasing and I don't get I get how to do decreasing just not increasing

Answers

so assume that 24 is 100%

what percent is 78

24 times 3=72
get close to the number
78-72=6
find the remainder
6=1/4 of 24
figure out the fraction
3-1+1/4=2 and 1/4
2=200%, 1/4=25%
the answer is 225%

What value of x will make this proportion true? a. 7 b. 18 c. 24 d. 28 42 3 4 = 14 x 1 2

Answers

We are given proportion as 14/x = 1/2

So first step is to get rid off 2 from denominator,so we multipy both sides by 2

2(14/x) =2(1/2)

28/x =1

Next step is to get rid off x from denominator ,so we multiply both sides of the equation by x

x(28/x) =x(1)

28x/x =x

28 =x

Hence we get value of x =28

So answer is choice d) 28
