aliina [53]3 years ago

Answer:

(-5,-8)

(2,-8)

(-3,-4)

Step-by-step explanation:

Please refer to the image attached with this answer. Please see that we are required to shift the ΔABC 8 units to the left. We just need to shift it to left. Hence the changes will occur in x coordinates only. Each of the x coordinates of the original triangle will be shifted to left by 8units. Hence we just subtract 8 from each x coordinates. It gives us a new triangle ΔA'B'C' whose coordinates will be

(-5,-8)

(2,-8)

(-3,-4)

Find the exact area of a circle with a dimeter of 5 yards. Use 3.14 for pi
kenny6666 [7]

Answer:

A = 6.25(pi)

A ~ 19.63495

Step-by-step explanation:

The formula for finding the area of a circle is;

A = (pi)r^2

Where (A) represents the area of the circle, (pi) represents the value (3.1415...) and (r) represents the radius of the circle. As per its definition, the diameter is the largest cord or line segment that can be drawn through a circle, the diameter always passes through the center of a circle. The radius ( a line segment that can be drawn from the center of the circle to any side of the circle) is always half of the diameter.

This means that the radius for the given circle is (2.5), since (5÷2=2.5)

Substitute these values into the equation and solve for the area of the circle.

A = (pi)r^2\\\\A = (pi)(2.5)^2\\\\A = (pi)6.25\\

A ~ 19.63495

The sum of two numbers is 60 and the difference is 2 what are the numbers.
oksian1 [2.3K]
Let the two numbers be x and y
Then
x + y = 60
And
x - y = 2
x = y + 2
Putting the value of x in the first equation we get
x + y = 60
y + 2 + y= 60
2y + 2 = 60
2y = 60 - 2
2y = 58
y = 58/2
y = 29
Now putting the value of y in the first equation we get
x + y = 60
x + 29 = 60
x = 60 - 29
x = 31
So the value of the two numbers comes out to be 31 and 29. I hope the procedure is clear enough for you to understand.

(a) Write 14 as a decimal.​
Yuliya22 [10]

Answer:

0.14

Step-by-step explanation:

14% describes 14 out of 100. It is written as 14 in the numerator and 100 in the denominator of a fraction. A percent is always written as the number over 100 as a fraction. “Out of 100” refers to the decimal place “hundredths.” 14% is 14 hundredths.
