. A triangle has vertices on a coordinate grid at points J(-1, 5), K(4, 5), and L(4, -2). What is the length, in units, of ?

Answers

Answer 1

Answer:

20.6

Step-by-step explanation:

Given data

J(-1, 5)

K(4, 5), and

L(4, -2)

Required

The perimeter of the traingle

Let us find the distance between the vertices

J(-1, 5) amd

K(4, 5)

The expression for the distance between two coordinates is given as

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((4+1)²+(5-5)²)

d=√5²

d= √25

d= 5

Let us find the distance between the vertices

K(4, 5), and

L(4, -2)

The expression for the distance between two coordinates is given as

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((4-4)²+(-2-5)²)

d=√-7²

d= √49

d= 7

Let us find the distance between the vertices

L(4, -2) and

J(-1, 5)

The expression for the distance between two coordinates is given as

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((-1-4)²+(5+2)²)

d=√-5²+7²

d= √25+49

d=  √74

d=8.6

Hence the total length of the triangle is

=5+7+8.6

=20.6

b) What is the power of y in 3y+2=14
c) What is the value of x such that x+7-19 is a true statement?​

Answers

3y+2=14

Subtract 2 from both sides.

3y=12

Divide 3 from both sides.

y=4

Now for the second part. We'll do the same process as the first one.

What is the question

the diameter of a baseball is approximately 3 inches. what is it's volume? round your answer to the nearest whole number. ​

Answers

Answer:

14.14in cubed

Step-by-step explanation:

formula for volume of sphere is 4/3 x pi x radius to the power of three.

Since the diameter is 3, to find the radius we need to divide 3 by 2. So the radius is 1.5.

plug 1.5 in formula:

4/3 x pi x 1.5 to the power of 3

anwser: 14.14 or in terms of pi is 4.5pi inches cubed

What’s the length of diagonal AC

A. 7.8cm

B. 10cm

C. 15.6cm

D. 3.9cm

Answers

Answer is C: 15.6

Explanation: 7.8*2

The solution is Option C.

The length of the diagonal of the rhombus is AC = 15.6 cm

What is the perimeter of Rhombus?

A Rhombus has four sides of the same length, its perimeter can be determined using the formula Perimeter = 4a, where "a" stands for the side's length.

When the two diagonals of a rhombus are known,

The perimeter = 2√p² + q²

where 'p' and 'q' are the diagonals.

Given data ,

Let the diagonal of the rhombus be represented as ABCD

Now , the diagonals of the quadrilateral bisects at the angle O , and the quadrilateral is a rhombus

Substituting the values in the equation , we get

The measure of side AC = measure of side BD

And ,

The measure of side AO = The measure of side OC

So ,

The measure of side AC = 2 ( measure of side OC )

On simplifying the equation , we get

The measure of side AC = 2 x ( 7.8 ) cm

The measure of side AC = 15.6 cm

Hence , the measure of side AC is 15.6 cm

$7,960.00

$7,960.93

$7,970.93

Answers

Answer:

The answer is $7,960.93

Step-by-step explanation: 99.9% sure (sorry for being late)

The amount is the closest to the account balance at the end of 5 years is   $175692.

What is simple interest?

Simple interest rate is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time peroid.

Simple Interest = (Principal × Rate × Time) / 100

Given;

Since the deposited amount is $5,500

The interest rate is 1.2%

And, the time period is 5 years

So, here the amount at the end of 5 years should be

= 7500 x (1+1.2%)^4

= $175692

Therefore, the answer by the given rate will be $175692

The triangle is isosceles, so you know that the bottom two angles are congruent. You can subtract the top angle from 180, so 180 - 56 = 124/2 = 62, you then find the angle of the other triangles with that information, you subtract 180 - 62 = 118, 180-118=62/2=31

X/2.7 + 3.6=4.8 solve for x

Answers

Answer:

3.24

Step-by-step explanation:

1) minus the whole number, 3.6 from both sides:  

   x/2.7 +3.6 = 4.8 -----> x/2.7 = 1.2

2) multiply both sides by 2.7 to get the x value on its own:  

   x/2.7 = 1.2 -------> x = 3.24

3) finally x is on its own with a value on the other side... x = 3.24
