If Oscar can make 5 doughnuts every 2 minutes, exactly how many minutes
would it take him to make 36 doughnuts?
Lisa and Marie are both on the track team. During practice, Lisa ran 10 laps around
the track in 18 minutes. Marie ran 8 laps around the track in 14 minutes. Who ran at a
faster rate? If each runner continues at her same pace, how long would it take each
one to run 15 laps?
Answer:
Marie ran at a faster rate. It takes 27 minutes for Lisa to run 15 laps while it takes Marie 26.25 minutes to run 15 laps.
Step-by-step explanation:
18 ÷ 10 = 1.8 (Lisa's rate)
14 ÷ 8 = 1.75 (Marie's rate)
1.8 x 15 = 27 minutes (How long it takes for Lisa to run 15 laps)
1.75 x 15 = 26.25 (How long it takes for Marie to run 15 laps)

Find the measure of the missing angles.
Answer:
angles b and c should be 153° each.
Step-by-step explanation:
We know the smaller angle is 27°. The other small angle, vertical to the 27° angle is also 27° because they are vertical angles. Along the lines, two angles should form 180°. So 180-27=153°. All together the angles should be 360°. Check your answer by doing 153+153+27+27=360. therefore the missing angles are both 153°

This rule is given triangle is reflection about origin or
Rotation clockwise or counter clock wise with 180°
Step-by-step explanation:
Explanation:-
A triangle has coordinates at X(3,7),Y(6,7) and Z(4,2)
The Rule ( x, y)→ ( - x, -y)
This rule is given triangle is reflection about origin or Rotation clockwise or counter clock wise with 180°
X( 3,7) → X¹ ( -3,-7)
Y(6,7) → Y¹ (-6,-7)
Z(4,2) → Z¹( -4 ,-2)

Solve for n: 21 K - 3n + 9 p is greater than 3 p + 12
Answer:
n > p + 1 + 7k
Step-by-step explanation:
21k - 3n + 9 > 3p + 12
21k - 3n > 3p + 12 - 9
3n > 3p + 3
3n > 3p + 3 + 21k
n > (3p + 3 + 21k)/3
n > p + 1 + 7k

Triangle A is a scaled version of triangle B. The dimensions of triangle B are twice the dimensions of triangle A. The area of
triangle B is 144 sq cm.
What is the area of triangle A?
Answer:
576 sq cm
Step-by-step explanation:
For example imagine a rectangle, the area of which is width * height = area
If you multiply the dimensions by 2 you multiply the width AND the height which is 2 * width * 2 * height = 4 * width * height
This is true for all scalings, if you times the dimensions by n, you times the area by n^2
144 * 2^2 = 576
which binomial is a factor of 8x^2y^3-18y
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
[tex]8x^2y^3-18y[/tex]
Apply exponent rule: [tex]a^{b+c}=a^ba^c[/tex]
[tex]8x^2y^3-18y=8yy^2-18y[/tex] ∵ [tex]x^2y^3=yy^2[/tex]
[tex]=4\cdot \:2yy^2+9\cdot \:2y[/tex]
Factor out common term 2y
[tex]=2y\left(4x^2y^2-9\right)[/tex]
We know that the Binomial is an expression that consists of two terms. Thus,
(4x²y²- 9) represents the binomial factor of [tex]8x^2y^3-18y[/tex]
We can further simplify by Factoring 4x²y² - 9: (2xy + 3) (2xy - 3)
[tex]=2y\left(2xy+3\right)\left(2xy-3\right)[/tex]
Here:
(2xy + 3) and (2xy -3) are the binomial factors of [tex]8x^2y^3-18y[/tex] as each of them consists of two terms.
What is the solution to this system of equations?

(3.)
no solution
infinitely many solutions
Answer:
X+2y=4
4+2y=x
2(2+y)=x
2x-2y=5
2(x-y)=5
x-y=5/2
Answer:
(x, y) = (3, 1/2)
Step-by-step explanation:
x + 2y = 4
2x - 2y = 5
There is more than one way to do this. I will do it by substitution.
From the first equation, x + 2y = 4, so x = (-2y) + 4
Now, in the second equation, I will replace x with (-2y + 4)
2(-2y + 4) - 2y = 5
-4y + 8 -2y = 5
-6y + 8 = 5
-6y = -3
6y = 3
y = 3/6
---------------------------------> y = 1/2, one part of the answer
Now I can go back to the first equation, and relpace 'y' with 1/2
x + 2(1/2) = 4
x + 1 = 4
-----------------------------------> x = 3, the other part of the answer
So now we believe the solution is (x, y) = (3, 1/2)
Now check the answer, back in the original equations!!
------> In the first equation, we would have 3 + 2(1/2) = 4.
3 + 1 = 4
That is true
-------> In the second equation, we would have 2(3) - 2(1/2) = 5
6 - 1 = 5
That is true
Our answer is found and checked.
(x, y) = (3, 1/2)
