Answer:

r = 24.41cm

Step-by-step explanation:

If you're only trying to find the radius, use the equation:

Area = \pi r^2

When rearranged to make r the subject:

r = \sqrt\frac{Area}{\pi }

When the variables are added:

r = \sqrt\frac{1872}{\pi }

r = 24.41

1) check if they given ordered pairs are solutions to the equation or not.
ziro4ka [17]
Answer: a) Yes
b) No


Explanation: Substitute the values of X and Y from the given points into the equation. I’ll use a) as an example:
Given point: (1,-3)
Equation: 4x-2y=10
Value of X: 1
Value of Y: -3
Substitute X and Y: 4(1)-2(-3)=10
4-(-6)=10
4+6=10 ✔︎

Therefore, the given ordered pair is a proper solution to the equation 4x-2y=10.

*You can use the same method for question b).*

BlackZzzverrR [31]

Answer:

<h2>Total yards of ribbon bought is 6.993yards of ribbon</h2>

Step-by-step explanation:

Total pieces of ribbon James bought for his craft project = 10pieces. If each pieces of ribbon were 2.1feet long, the total number of feet for 10ribbons is expressed as;

= 10 * 2.1\\= 21feets

Converting 21 feets to yards;

1 feet = 0.333yard

21feets = x

x = 21feet * 0.333\\= 6.993yards

Total yards of ribbon bought is 6.993yards of ribbon

In 1 hour, Antoine travels 1.75 mi by dividing 5.25 by 3. So, after lunch, he hiked 4 hours. 1.75 times 2 is 3.5 mi every hour after lunch. So, 3.5 times 4 is 14 mi. + 5.25 is 19.25 mi., or 19 1/4 miles.

What is the value of x? I don’t understand this please help
Monica [59]

Answer:

54

Step-by-step explanation:

A tangent line makes a right angle with the radius to the point of tangency. Hence this triangle is a right triangle, and x° is the complement of 36°:

x° = 90° -36° = 54°

The value of x is 54.

Clare and Noah play a game in which they earn the same number of points for each
Korvikt [17]

6x+3y=6  and 8x+9y= -22  describes the outcomes of Clare and Noah.

Step-by-step explanation:

Let,

x represents the number of points for a goal.

y represents the number of points for a penalty.

Therefore,

6 goals = 6x

3 penalties = 3y

8 goals = 8x

9 penalties = 9y

According to given statment;

6x+3y=6    Eqn 1

8x+9y= -22   Eqn 2

6x+3y=6  and 8x+9y= -22  describes the outcomes of Clare and Noah.
