Answers
x=10; y=−5x+30
Step: Solve x=10
for x: x=10
Step: Substitute
10 for x in y=−5x+30:
y=−5x+30
y=(−5)(10)+30

Will a 11.5-inch x 18-inch rectangular tray fit in
the box shown? Explain.
Answers
Answer:
Option D
Step-by-step explanation:
From the picture attached,
In the parallelogram ABCD,
Length of diagonals AC and BD are equal.
By the property,
"If the lengths of the diagonals of a parallelogram are equal, parallelogram will be a rectangle".
Therefore ABCD is a rectangle.
That means all interior angles of the given rectangle will be 90°.
Now we apply Pythagoras theorem in right triangle ΔABC,
AC² = AB² + BC²
(22)² = (12)² + (BC)²
484 - 144 = (BC)²
BC = √340
BC = 18.44 inches
Dimensions of the given box are 12 inches by 18.44 inches.
Dimensions of the rectangular tray is 11.5 inches by 18 inches.
Since, dimensions of the box are larger than the dimensions of the tray, tray can be adjusted in the box.
Therefore, Option D will be the answer.

Step-by-step explanation:
That person added everything together that was shown which is incorrect. You shouldn't add the 12x + 3 as that should be the end result. You add 3x + 3x + 4x + 2 to get 10x + 2. You then subtract that by 12x +3 which is 2x + 1
Mark is going to an awards dinner and wants to dress appropriately. He had one blue shirt, one white dress shirt, one black dress shirt, one pair of black slacks, one pair of grey slacks, and one red tie. All six of marks possible outfits are listed below
Answers
Answer:
All the four statements are true , which are -
(A) The subset contains contains of all the outfits that have grey slacks .
(B) The subset contains contains of all the outfits that have grey slacks and red tie .
(C) The subset contains contains of all the outfits that have grey slacks and blue shirt .
(D) The subset contains contains of all the outfits that do not have black slacks .
Step-by-step explanation:
We are given with Outfit 2 , 4 and 6
Outfit 2 - Blue grey red
Outfit 4 - White grey red
Outfit 6 - Black grey red
(A) Since only 2,4, and 6 contain grey slacks, and no other outfit contains grey slacks, those are the subsets that contain grey slacks. Thus , this statement is true .
(B) Just outfits 2, 4, and 6 have grey slacks and a red tie, proving the statement. Other clothes do not include grey slacks and a red tie; they may include a red tie but not both grey slacks and a red tie. Hence , the statement is true .
(C) Since the outfit 2 has grey slacks and a blue shirt, the statement is correct; no other outfit has both grey slacks and a blue shirt. Therefore , this statement is also correct .
(D) The argument is correct since all of the subsets contain grey slacks and no black slacks.
Hence , all the options A , B , C , D are correct and describes the subset .

Zack bought a large box of microwave popcorn. The box contained 3 bags of butter-flavored popcorn for every 2 bags of plain popcorn. If the box contained 12 bags of plain popcorn, how many bags of microwave popcorn did it contain altogether?
Answers
Answer: 30
Step-by-step explanation:
Let the number of butter-flavored popcorn be represented by x.
Based on the information given in the question, we can generate an equation which will be:
3/2 = x/12
Cross multiply
2 × x = 3 × 12
2x = 36
x = 36/2
x = 18
There are 18 butter-flavored popcorn.
Therefore, the bags of microwave popcorn contain altogether will be:
= 12 + 18
= 30

A teacher calculated the mean of 27 students mark to be 62. A student who later completed the assessment got a mark of 53. What is the new mean of the class, to two decimal places?
Answers
Answer:
first of all the average score of students is 62.
and there are 27 students
so full marks scored by students are 27×62= 1674
and 1 new students added to that so his score would be 1674+ 53(his marks)= 1727
so now the mean of students are beause there are one more students so 27+1 = 28 then 28÷1727= 61.6 is the mean now

What is graph of a linear equation?The graph of a linear equation is a straight line on a Cartesian coordinate system. A linear equation can be represented in the form y = mx + b, where m is the slope of the line, and b is the y-intercept (the point where the line intersects the y-axis).
The graph of a linear equation can have different orientations and slopes, depending on the values of m and b. It can be upward-sloping (positive slope), downward-sloping (negative slope), or horizontal (slope of 0). The steepness of the line is determined by the magnitude of the slope.
Using a graphing calculator, the slope of the equation is 1 and the y-intercept is 6.

[tex]20^{\circ}[/tex]
Step-by-step explanation:
We can see here that the two unknown angles are on the straight line . So its measure will be 180° .
[tex]\implies (4x + 20^{\circ})+(x-15^{\circ}) = 180^{\circ} \\\\\implies 5x + 5^{\circ} = 180^{\circ} \\\\\implies 5x = 175^{\circ} \\\\\implies x =\dfrac{175^{\circ}}{5}\\\\\implies x = 35^{\circ} [/tex]
Now the angle F and the angle (x-15)° are vertically opposite angles . So they will be equal .
[tex]\implies x - 15^{\circ} \\\\\implies 35^{\circ} - 15^{\circ} \\\\\implies \boxed{ 20^{\circ} } [/tex]

What is the equation of a circle that has a diameter of 10 units if its center is at (3,8)?
Answers
Answer:
Step-by-step explanation:
[tex](x-3)^2+(y-8)^2 = 25[/tex]
The equation of circle: (x - 3)² + (y - 8)² = 25
What is equation of circle?An equation of circle with center (h, k) and radius 'r' is,
(x - h)² + (y - k)² = r²
For given example,
a diameter of circle = 10 units
So, the radius would be (r) = 10/2
r = 5 units
And the center (h, k) = (3, 8)
So, the equation of the circle would be,
⇒ (x - 3)² + (y - 8)² = 5²
⇒ (x - 3)² + (y - 8)² = 25
Therefore, the equation of circle: (x - 3)² + (y - 8)² = 25
