Answer:
5:1
Step-by-step explanation:
So, we know that 20 fries were large, and 4 were small. So, we just set it up as 20:4 (for every 20 large fries, there are 4 small ones). However, it needs to be simplified which results in 5:1.

determine the equation of the circle if its center is (8,-6) and which passes through the points (5,-2).
Answer:
(x - 8)² + (y + 6)² = 25
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
Here (h, k ) = (8, - 6 ) , then
(x - 8)² + (y - (- 6))² = r² , that is
(x - 8)² + (y + 6)² = r²
The radius is the distance from the centre to a point on the circle
Calculate r using the distance formula
r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (8, - 6 ) and (x₂, y₂ ) = (5, - 2 )
r = [tex]\sqrt{(5-8)^2+(-2-(-6))^2}[/tex]
= [tex]\sqrt{(-3)^2+(-2+6)^2}[/tex]
= [tex]\sqrt{9+4^2}[/tex]
= [tex]\sqrt{9+16}[/tex]
= [tex]\sqrt{25}[/tex]
= 5
Then equation of circle is
(x - 8)² + (y + 6)² = 5² , that is
(x - 8)² + (y + 6)² = 25
PLS help me i am so confused and i am lazy and clueless, A boat travels 3/4 hour at 8mph and then 1/3 hour at 12mph. What distance does the boat travel? HELP MEEEEEE
The total distance travelled by the boat is 12 miles
How to find distance travelledAverage speed = distance / timeDistance = Speed × timeDistance 1 = 8 mph × 3/4 h
= (8 × 3) / 4
= 24/3
= 8 miles
Distance 2 = 12 mph × 1/3 h
= (12 × 1) / 3
= 12/3
= 4 miles
Total distance = Distance 1 + Distance 2

3C. Point D is on side BC of equilateral ▲ABC. From point D, perpendicular line segments with lengths 4 and 8 inches are drawn meeting sides AB and AC at points R and T. Find the number of inches in the height of ▲ABC. [Hint: Draw a line segment from A to D.] BRAINLEST GIVEN
Correct response:
The height of triangle ΔABC is 12 inches.Method used for finding the heightThe given parameters are;
ΔABC is an equilateral triangle;
DR = 4 inches
DT = 8 inches
Required:
The height of ΔABC
Solution:
Let θ represent the angle formed by the line from A to D towards the 4 inches side, we have;
[tex]AD = \dfrac{4}{sin(\theta)} = \mathbf{\dfrac{8}{sin(60^{\circ} - \theta)} }[/tex]4·(sin(60° - θ) = 8·sin(θ)
4·(sin60°·cos(θ) - cos(60°)·sin(θ)) = 8·sin(θ)
Dividing by sin(θ) and multiplying by 2 gives;
4·(√3·cot(θ) - 1) = 8 × 2 = 16
√3·cot(θ) - 1 = 16 ÷ 4 = 4
[tex]cot(\theta) = \dfrac{4 + 1}{\sqrt{3} } = \dfrac{5}{\sqrt{3} } [/tex]
[tex]tan(\theta) = \mathbf{ \dfrac{\sqrt{3} }{5} }[/tex]
[tex]tan(\theta) = \dfrac{DR}{AR} [/tex]
Therefore;
[tex]AR = \mathbf{\dfrac{DR}{tan(\theta)} }[/tex]
Which gives;
[tex]AR = \dfrac{4}{\dfrac{\sqrt{3} }{5} } = 4 \times \dfrac{5}{\sqrt{3} } = \mathbf{ \dfrac{20}{\sqrt{3} } }[/tex]
[tex]RB = \mathbf{\dfrac{4}{tan(60^{\circ})}} = \dfrac{4}{\sqrt{3} } [/tex]
AB = AR + RB by angle addition property
Height = AB × sin(∠B) = (AR + RB) × sin(∠B)
Therefore;
[tex]Height \ of \ \Delta ABC, \ h = \left(\dfrac{20}{\sqrt{3} } + \dfrac{4}{\sqrt{3} } \right) \times \dfrac{\sqrt{3} }{2} =\dfrac{24}{\sqrt{3} } \times \dfrac{\sqrt{3} }{2} = \mathbf{ 12}[/tex]

If the length of a rectangle is five less than three times its width and the perimeter is 105
inches, what is its width? Length?
Answer:
Mark me Brainliest please
Answer : W = 14.375 inches
L = 38.125 inches
Step-by-step explanation:
Suppose the length of the rectangle is : L
and Width of the Rectangle is : W
As per the the given question
L = 3W -− 5 ---------- (1) // Length is five less than three times its width
Given Perimeter = 105 inches
2( L + W ) = 105 ---------- (2)
Put the value of L from equation (1) to equation (2)
2( 3W -− 5 + W)= 105
6W -− 10 + 2W = 105
8W -− 10 = 105
8W = 115
W = 14.375
Put the value of W in the equation (1)
L = 3W -− 5
L = 3*∗14.375 -− 5
L = 43.125 -− 5
L = 38.125
Answer : W = 14.375 inches
L = 38.125 inches

two people who have never been there before

The probability they will choose a restaurant that only one of them has

What is Probability Selection?
We are told that both Amna and Mani are choosing a restaurant for lunch.
Now, decide to choose a restaurant at random from the first 10
search results in the neighborhood.
Each of them have been to 3 restaurants out of the 10. The 3 each have visited differ from each other.
Thus;
Probability that Amna will choose a restaurant visited before = 3/10
Probability that Mani will choose a restaurant visited before = 3/10
probability they will choose a restaurant that only one of them has
been to before = 3/10 + 3/10 = 6/10 = 0.6
