Given:
The two points on a coordinate plane are C(-5,-1) and D(0,3).
To find:
The distance between C and D.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, the distance between C(-5,-1) and D(0,3) is
[tex]CD=\sqrt{(0-(-5))^2+(3-(-1))^2}[/tex]
[tex]CD=\sqrt{(0+5)^2+(3+1)^2}[/tex]
[tex]CD=\sqrt{(5)^2+(4)^2}[/tex]
[tex]CD=\sqrt{25+16}[/tex]
On further simplification, we get
[tex]CD=\sqrt{41}[/tex]
[tex]CD=6.40312424[/tex]
[tex]CD\approx 6.40[/tex]
Therefore, the distance between C and D is 6.40 units.

Jonathan is putting a border around a right triangle and needs to figure out the triangle's height. If the triangle has a base length of 4 cm and a total area of 24 cm², what is the height?
Step-by-step explanation:
formula to find area of a triangle:
A=1/2 × base × height(h)
insert the values into the formula:
24=1/2 × 4 × h
solve for h :
24=2h
24/2=h
h = 12 cm ( Ans )
The height of triangle will be 12 cm.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The triangle has a base length of 4 cm.
And, A total area of 24 cm².
Now,
We know that;
Area of right triangle = 1/2 × Base × Height
⇒ 24 = 1/2 × 4 × h
⇒ 24 = 2 × h
⇒ h = 24 / 2
⇒ h = 12 cm
Thus, The height of triangle = 12 cm.

Karla rode her bicycle 135 miles in 9 weeks, riding the same distance each week. Brad rode his bicycle 102 miles in 6 weeks, riding the same distance each week. Which statement correctly compares the number of miles per week they rode?
Answer:
Karla's 15 miles per week to Brad's 17 miles per week.
Step-by-step explanation:
First, we would need find the total number of miles each individual rides per week. We do this by dividing the total miles ridden by the number of weeks it took for each individual like so...
Karla: 135 / 9 = 15 miles per week
Brad: 102 / 6 = 17 miles per week
Finally, the comparison would be
Karla's 15 miles per week to Brad's 17 miles per week.
Answer:

3/4 + (1/3 divided by 1/6) - (-1/2) = ?
Iready diagnostics.
Answer: 13/4
Step-by-step explanation:
First you have to solve the equation in the parenthesis.
1/3 divided by 1/6 = 2
3/4 + 2 = 11/4 or in decimal form: 2.75
11/4 - (-1/2) btw... the subtraction and the negative together cancel out and become addition.
11/4 + 1/2 = 13/4 or in decimal form 3.25
Answer:
13/4
Step-by-step explanation:
Q:-3/4+(1/3 ÷1/6)-(-1/2)
A:-3/4+(1/3×6/1)+1/2
=3/4+2+1/2
=3+2/4 +2
=5/4+2
=5+8/4
=13/4

what was the original weight of the ball ?
Answer:
16.5
Step-by-step explanation:
A is the correct answer
Step-by-step explanation:
If you plug y=x+10 in for the Y variable you just have to solve by multiplying.
1.) It should look like this:
2x + 3(x +10) = 40
2.) You will distribute the three which will make the equation look like this:
2x + 3x + 30 = 40
3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.
but 16.5 is the answer
