Find the distance between C(-5,4) and Q(2,0)
9514 1404 393
Answer:
√65 ≈ 8.06
Step-by-step explanation:
The distance formula is used for the purpose.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((2 -(-5))² +(0 -4)²) = √(7² +(-4)²) = √(49 +16)
d = √65 ≈ 8.0622577
The distance between C and Q is √65, about 8.06 units.

Karl is replacing his concrete driveway with rectangular pavers. Each paver has an area of 4.5 square feet. Karl's driveway is 21 feet long and 18 feet wide. How many pavers will he need?
Answer:
84
Step-by-step explanation:
To complete the concrete highway with pavers 84 pavers are needed.
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
From the given information each Pavel has an area of 4.5 square feet.
And the area of the driveway can be obtained by multiplying the length and width of the driveway which is,
= (21×18) sq feet.
= 378 sq feet.
Therefore, The number of pavers needed is,
= (378/4.5).
= 84 pavers.

An isosceles triangle has two congruent side lengths of 20 centimeters. The base of the triangle is 10 centimeters. Find the height of the
isosceles triangle
(Use the Pythagorean Theorem & DONT GIVE ME THE ANSWER, I JUST WANT THE EQUATION) Thx :)
Answer:
(half of base)² + (height)² = (20)²
Step-by-step explanation:
In an isosceles triangle, the angle bisector from the 3rd angle to the opposite side is a perpendicular bisector, so you split the isosceles triangle into two congruent right triangles.
This technique of 'splitting the isosceles' is used a LOT.
Add a grocery store bananas cost $.90 each and oranges cost $.80 each Ava has $15 to spend if Ava wants to buy an equal amount of bananas and oranges at most how many of each can't you buy
Answer:
9
Step-by-step explanation:
We are given that
Cost of each banana=$0.90
Cost of each orange=$0.80
Ava have total money=$15
We have to find the number of each if Ava wants to buy an equal amount of bananas and oranges at most.
Let x be the number of each.
According to question
[tex]0.9x+0.8x=15[/tex]
[tex]1.7x=15[/tex]
[tex]x=\frac{15}{1.7}[/tex]
[tex]x=8.8\approx 9[/tex]
[tex]x=9(approximately)[/tex]
Hence, number of banana bought=9
Number of oranges bought=9

Are 25 milligrams lighter or heavier than 25 centigrams
Please help it's for homework and it says explain too so please help
Answer:
25 mg. is lighter than 25 cg.
Step-by-step explanation:
Well,
The prefix "milli" means thousandth and the prefix "centi" means hundredth. So a milligram will be one-tenth of a centigram.
10 mg. = 1 cg.
25 mg. = 2.5 cg.
2.5 cg. < 25 cg.
25 mg. is lighter than 25 cg.
Answer:
25 milligrams are lighter, because 1 milligram equivales to 1 gram multiplied by 100.

11. The slope of a line is 1/5. Label the two right
triangles with dimensions that would allow the
triangles to lie on the same line.
Answer:
Step-by-step explanation:
If the slope is 1/5, we can interpret this as rise/run = 1/5. We could (if we wished to do so) find the hypotenuse by using the Pythagorean Theorem:
hypo = +sqrt( 1^2 + 5^2)
In this case we dilate the triangle defined by the slope 1/5:
2/10, 1/10/(1/2), 10/50, etc., all represent right triangles whose hypotenuses lie on the same line (the line with slope 1/5).
The two right triangles are shown in the graph
What are coordinates?The coordinates in rectangular cartesian system are of the form -
(x, y)
where -
{x} - distance along x - axis.
{y} - distance along y - axis.
Given is the slope of the line as - {m} = 1/5.
Refer to the graph attached. The line -
y = (1/5)x
is plotted. It can be seen that (0, 0) and (10, 2) lie on the line. For two right triangles to lie on the same line, draw two perpendiculars from point (10, 2) along the {x} axis and {y} axis. Refer to the triangles shown in the graph.
Therefore, two right triangles are shown in the graph.
