Answer:
2 and 10
Step-by-step explanation:
We will assume to numbers represented by x and y.
From the question, we can write the following :
sum = x + y
difference = x - y
product = xy or x*y
Since we have two unknowns, general rule of thumb is that we require
2 equations to solve for them.
Using the ratio, of sum: difference and sum : product,
I can form these 2 equations:
(x + y) / (x -y) = 3/2 (1)
(x + y) / (x*y) = 3/5 (2)
In (1),
we cross multiply and do some tidying we will get
x = 5y
In (2),
we have 5x + 5y = 3x*y
We can then substitute x = 5y into (2) and get the following
5*5y + 5y = 3*5y*y
30y = 15y^2
2y = y^2
y^2 - 2y = 0
After factorization,
y(y - 2) = 0
you will have to options either use y = 0 or y = 2
If we use 2, then using equation (1),
we can solve for x which is 10.
Answer:
2 , 10
Step-by-step explanation:
(x+y) / (x-y) = 3/2 ..(1)
3x-3y = 2x+2y
x = 5y
(x+y) / xy = 3/5
(5y+y) / (5y*y) = 3/5
6y/5y² = 3/5
15y² = 30y
y = 2
x = 10
check: (2+10) : (10-2) : (10*2) = 12 : 8 : 20 = 3 : 2 : 5
What is the correct answer I’m offering brainalist + 10 points don’t just say A please can you explain to me why you chose what you chose
Answer:
Answer is Complementary.
Step-by-step explanation:
This is because complementary angles add up to 90 degrees. In this example, the angles are exactly 45 degrees. Therefore, because there are two angles 45 * 2 is 90. Answer is B.
Answer:
D. vertical
Step-by-step explanation:
We can rule out A and B because they wont equal 180 or 90 they will be somewhere in between. We can rule out C because those are acute angles. So we are left with D. These angles are vertical because they are opposite angles made by two intersecting lines and they have equal values.

Answer:
B) 60.21 ft²
Step-by-step explanation:
Area of a triangle = 1/2bh
You can‘t used mixed measurements (feet and inches), so you have to convert each length to inches
8’6”=102’
14’2”=170’
Now find the area
1/2 x 102 x 170 = 8670 in²
This is one of the answers, but the quetion asks how many quart feet you need.
So, convert it back to feet.
8670 x 0.06944444444 = 60.2083333
(You could also have converted the two lengths to feet. 8’6” = 8.5 ft. 14’2” = 14.16666666. This way would probably have been faster.
1/2 x 8.5 x 14.166666 = 60.20833333)

How much force is needed to stop a 1,400 kg truck pulling up to a stop light if
the truck took 4 seconds to stop and was moving at 36 m/s? If you know the answer please include the equation, it would really help me out, thank you! This is not math is is science btw.
Hi there!
[tex]\large\boxed{-12,600 N}[/tex]
Recall that the equation to calculate force is:
F = m · a where m = mass, a = acceleration, and F = net force.
Since we are given the velocity, and time needed to stop, we can calculate the acceleration using the following kinematic equation:
vf = vi + at
The initial velocity is 36 m/s and the final velocity is 0 m/s, therefore:
0 = 36 + at
Move 36 to the other side and plug in the given time:
-36 = 4a
Divide both sides by -4 to find a:
-36/4 = a
a = -9 m/s².
Since the acceleration is -9 m/s² and the mass is 1400 kg, use the above force equation to solve:
F = -9 × 1400 = -12600 N. (negative refers to the force working in the opposite direction of the car's travel. If simply needing the magnitude of the force, it would be 12600 N)

(11+x)/2-(9x-3)/4 x=3
Answer:
(11+X)/2-(9x-3)/4 x=3
subsititute 3 into all x
(11+3)/2-(9*3)-3)/4
first solve the first diviision
2-(9 times 3)-3/4
=2-(27-3)/4
=2-(24)/4
since the "2-" is there, you have to subtract it from 24 before you dividewhich would then be
22/4=5.5(in decimal form)
DON'T forget you have another bracket waiting for you since you were given 3 brackets. bring the first bracket down
2-(9x-3)/4 was solved and we got 5.5, so basically we are "substituting 5.5 into that part of the question)
11+x/5.5
11+3/5.5
14/5.5
=2.54 which is your final answer
Sorry if I went overboard lol.
Step-by-step explanation:
yes, the answer is 2.54 I believe.

thirty percent of all seventh graders own a bracelet. explain whether the sample closely estimates the percentage of seventh graders who own a bracelet.
30 seventh graders, 3 own a bracelet
The sample of 3 seventh graders who own a bracelet out of 30 seventh graders does not closely estimate the thirty percent of all seventh graders owning bracelets.
What is a percentage?Percentages are fractions where the denominator is 100.
We have,
Number of seven grade students = 30
Number of students who own a bracelet = 3
The percentage of seven grade student who owns a bracelet:
= (3 / 30) x 100
= (1/10) x 100
= 10 %
This means that 10% of seven grade student owns a bracelet.
Thus, the sample does not closely estimate the percentage of seventh graders who owns bracelets.

There are 12 pieces of candy in a bowl. 6 are mints, 4 are Butterscotch, and 2 are Cinnamon.
What is the probability of Mr. Binder pulling
Butterscotch from the bowl, putting it back, and
then choosing mint? P(Butterscotch, then mint)
Answer:
1/6
Step-by-step explanation:
total = 12
number of butterscotch = 4
number of mint = 6
Since he replaces the mint, these events are independent events.
p(butterscotch, then mint) = p(butterscotch) * p(mint)
p(event) = (number of desired outcomes)/(total number of outcomes)
p(butterscotch) = 4/12 = 1/3
p(mint) = 6/12 = 1/2
p(butterscotch, then mint) = p(butterscotch) * p(mint)
p(butterscotch, then mint) = 1/3 * 1/2
p(butterscotch, then mint) = 1/6

Parallelogram ABCD is shown on the coordinate grid. Which
coordinates belong to a point that appears to lie on segment AB?
Answer:
[tex](-1, 3)[/tex]
Step-by-step explanation:
Given
See attachment for ABCD
Options:
[tex](-1, 3)\ \ \ (0,3)\ \ \ (1,5)\ \ \ (2,5)[/tex]
From the attachment:
[tex]A = (-6,1)[/tex]
[tex]B = (4,5)[/tex]
Required
Coordinates on AB
First, calculate the slope of AB
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{5-1}{4--6}[/tex]
[tex]m = \frac{4}{10}[/tex]
[tex]m = 0.4[/tex]
Next,, calculate the equation as:
[tex]y = m(x - x_1) + y_1[/tex]
[tex]y = 0.4(x - -6) + 1[/tex]
[tex]y = 0.4(x +6) + 1[/tex]
[tex]y = 0.4x +2.4 + 1[/tex]
[tex]y = 0.4x +3.4[/tex]
Taking the options one at a time: (-1, 3)
[tex]x = -1\ \ y =3[/tex]
Test these values in the equation
[tex]y = 0.4 * -1 + 3.4[/tex]
[tex]y = -0.4 + 3.4[/tex]
[tex]y =3[/tex]
Hence, this point lie on AB
