I got it correct on a quiz I did that had this question.
A store clerk is stocking the shelves. He places on the shelf a box of cereal that weighs 850 grams, a box of granola bars that weighs 385 grams, and a box of crackers that weighs 435 grams. What is the total weight in kilograms?
16.70 kilograms

Based on your data, what is the experimental probability that the family has two dogs or two cats? (Heads= dogs and tails=cats)
My table:
Heads, Heads
15
Heads, Tails
9
Tails, Heads
16
Tails, Tails
10
Total
50
Also, please explain your answer.
Answer:
Two dogs: 30%
Two cats: 20%
Two dogs OR two cats: 50%
Step-by-step explanation:
Since the total is 50, we have to multiply all the numbers by two. The total will then 100, so one unit in each category will represent one percent. For example, 15 x 2 = 30, so the chance for two dogs is 30%.
If your question meant two dogs OR two cats as a single probability - not the individual probabilities of two dogs and two cat - then it is 50%, because 30 (two dogs) + 20 (two cats) = 50 (two dogs OR cats). I hope this helps! Sorry if my explanation doesn’t make lots of sense, I’m typing this off my phone. Feel free to ask any questions!
Find the value of x and m∠HKL.
Answer:
x = 25 degrees ∠HKL = 102 degrees
Step-by-step explanation:
The whole thing equals 180, since it is a straight angle
The value of HKL is 180 - 78 = 102
So that means 4x + 2 = 102
Subtract 2 from both sides:
4x = 100
Divide both sides by 4:
x = 25
6x^2 - 18x - 240 = 0
solve for x.
Find solutions that are greatest to least.
The greatest solution will be 8 and least solution will be -5.
A polynomial equation is given which is 6x² - 18x - 240 = 0
We have to find out the solutions that are greatest to least.
What do you mean by the quadratic equation ?
Quadratic equation is a polynomial equation whose highest degree is two . It is expressed in the form of ax² + bx + c = 0.
As per the question ;
Equation is ;
6x² - 18x - 240 = 0
Let's take 6 as common ;
6 ( x² - 3x - 40 ) = 0
or
x² - 3x - 40 = 0
This can be written as ;
x² - 8x + 5x - 40 = 0
x ( x - 8 ) + 5 ( x - 8 ) = 0
or
( x + 5 ) ( x - 8 ) = 0
or
x + 5 = 0
and
x - 8 = 0
So ;
x = - 5 and 8
Thus , the greatest solution will be 8 and least solution will be -5.

Is a triangle with leg lengths of 9 in. and 9 in. and hypotenuse of length √175 in. a right triangle?
Answer:
No
Step-by-step explanation:
a^2 + b^2 = c^2
9^2 + 9^2 = c^2
81 + 81 = c^2
162 = c^2
√162 = c
If it was a right triangle, its hypotenuse would be √162 inches long.

ΔPQR has angle measurements of 80°, 50°, and 50°. What kind of triangle is ΔPQR?
Answer:
Isosceles Triangle; Acute Triangle
Step-by-step explanation:
Review your definitions of the different types of triangles:
acute triangle- a triangle that has three acute (less than 90 degrees) angles
obtuse triangle- a triangle that has an obtuse (greater than 90 degrees) angle.
right triangle- a triangle that had one right (90 degrees) angles
isosceles triangle- a triangle with two congruent sides and one unique side and angle.
equilateral triangle- a triangle with three congruent sides and three congruent angles.
scalene triangle- a triangle with no congruent sides and no congruent angles.
With these definitions, we can classify ΔPQR as an isosceles acute triangle.

What is the result when 3/8x + 2 1/5 is subtracted from 3 1/2x - 4 1/10?
Don’t put a link.
Answer:
Option 3 3 1/8x - 6 3/10
Step-by-step explanation:
(3 1/2x - 4 1/10) - (3/8x + 2 1/5)
Divide it into parts:
(3 1/2x - 3/8x) + (-4 1/10 - 2 1/5)
3 1/2x - 3/8x = 3 4/8x - 3/8x = 3 1/8x
-4 1/10 - 2 1/5 = -4 1/10 - 2 2/10 = -6 3/10
So we get:
2 1/4x - 6 3/10
