Answer:
3 more trays
Step-by-step explanation:
At 35 cookies per tray, x trays is sufficient for an output of 840 cookies. Dividing 840 cookies by 35 cookies/tray, we get 24 trays.
But Ms. Sharp already has 21 trays.
Thus, she needs 3 more to be able to bake 840 cookies.
Ms Sharp will need to bake 3 more trays of cookies to meet the requirement of 840 cookies.
To determine how many more trays of cookies Ms. Sharp needs to bake, we first calculate the total number of cookies she has already baked. She baked 21 trays with 35 cookies on each tray:
[tex]\[21 \text{ trays} \times 35 \text{ cookies per tray} = 735 \text{ cookies}\][/tex]
Ms. Sharp needs a total of 840 cookies. Therefore, we need to find out how many more cookies are required:
[tex]\[840 \text{ cookies} - 735 \text{ cookies} = 105 \text{ cookies}\][/tex]
Each tray contains 35 cookies, so we need to determine how many more trays are required to bake 105 cookies:
[tex]\[\frac{105 \text{ cookies}}{35 \text{ cookies per tray}} = 3 \text{ trays}\][/tex]
Therefore, Ms. Sharp will need to bake an additional:
[tex]\[\boxed{3}\][/tex] trays of cookies.
Mary is 21 years old. Her age is 9 years more than 3 times Henry’s age. Which equation can be used to determine x, Henry’s age in years?
Answer:4
Step-by-step explanation:
21=3x+9
12=3x
X=4
Final answer:
To find Henry's age, use the equation 21 = 3x + 9, where x represents Henry's age which is 4.
Explanation:
The question asks to find the equation to determine Henry's age. Given that Mary is 21 years old and her age is 9 years more than 3 times Henry's age, we set up the equation as follows: Let x represent Henry's age. The equation then becomes 21 = 3x + 9. This equation can be used to solve for x, Henry's age which is 12 = 3x; x = 4.
There are 36 pencils in 6 packs. Igor wants to know how many pencils are in 1 pack. Elsa wants to know how many pencils are in 3 packs l.
In 1 pack there is 6 pencils cause you need to divide 36 by 6. In 3 packs there are 18 pencils because 6 pencils times 3 packs is 18 pencils!
Hope this helped!
Answer with step-by-step explanation:
We are given that there are 36 pencils in 6 packs and we are to find out how many pencils are there in one pack and three packs.
To find the number of pencils in one pack, we need to divide the number of pencils by the number of packs.
Number of pencils on 1 pack = 36/6 = 6 pencils
To find the number of pencils in 3 packs, we will multiply the number of pencils in one pack by 3.
Number of pencils in 3 packs = 6 * 3 = 18 pencils

Sara had 207 dollars to spend on 9 books. After buying them she had 18 dollars. How much did each book cost
Answer:
21
Step-by-step explanation:
207-18=189..then divide by 9
The problem involves subtracting Sara's remaining money from her initial amount to find the total spent on books, then dividing by the number of books, giving us that each book cost 21 dollars.
Explanation:This is a basic algebra problem where we need to find the cost of each book. Sara initially has 207 dollars and after buying 9 books, she has 18 dollars left. Therefore, we can calculate the total spent on books by subtracting the final amount from the initial.
The calculation is: 207 dollars - 18 dollars = 189 dollars.
Now, to find the cost of each book, divide the total spent by the number of books. So, 189 dollars divided by 9 books results in 21 dollars per book.

what is the area of this parallelogram
h=2in b=10in
Final answer:
The area of the parallelogram is calculated as the product of its base and height, resulting in 20 square inches.
Explanation:
The area of a parallelogram is calculated using the formula: Base x Height. In this case, the base (b) is 10 inches and the height (h) is 2 inches. Therefore, the area of the parallelogram can be found by multiplying the base by the height:
Area = Base x Height
Area = 10 in x 2 in
Area = 20 square inches
This calculation gives us the total area of the parallelogram in square inches.
The area of a parallelogram given its base and height dimensions as 10 in and 2 in is 20 square inches.
The area of a parallelogram can be calculated using the formula:
Area = Base x Height
Given that the base, b, is 10 inches and the height, h, is 2 inches, the area would be:
Area = 10 inches x 2 inches = 20 square inches

Given y = 4x + 3, what effect does changing the equation to y = 4x - 3 have on the y-intercept?
Answer:
The y-intercept changes from (0, 3) to (0, -3)
Step-by-step explanation:
The y-intercept refers to the point where the graph of a function crosses or intersects with the y-axis. At this point, the value of x is usually 0.
Substitute x = 0 in both equations to determine how the y-intercept changes;
The original equation is given as y = 4x + 3,
when x = 0; y = 4(0) + 3 = 3
The y-intercept is thus (0, 3)
The new equation is given as y = 4x - 3
when x = 0; y = 4(0) - 3 = -3
The y-intercept is thus (0, -3)
Therefore, the y-intercept changes from (0, 3) to (0, -3)

For the pattern given, the number of marbles in the sixth line is 5.
Given that:
"Starting with 10, every consecutive line has a number one less than the previous line."
This is the pattern of the positions of the marbles.
The first line has 10 marbles.
The second line has 10 - 1 = 9 marbles.
The third line has 9 - 1 = 8 marbles.
The fourth line has 8 - 1 = 7 marbles
The fifth line has 7 - 1 = 6 marbles
The sixth line has 6 - 1 = 5 marbles.
The number of marbles in any line will be 10 - (n - 1) marbles for any nth line.

Two angle are supplementary angle A has a measure of 3x+12 and angle B has a measure of 4x+28, what is the measure of each angle?
Answer:
A measures 72 and B measures 108
Step-by-step explanation:
If the angles are supplementary, that means that they add up to equal 180. 3x + 12 + 4x + 28 = 180. Doing some algebra there gives you that 7x = 140 and x = 20. Sub in 20 to angle A to get 3(20) + 12 = 72, and sub in 20 to angle B to get 4(20) + 28 = 108. And of course, 108 + 72 = 180.

ANSWER
[tex]y = \sqrt{x - 2} - 3[/tex]
EXPLANATION
The given equation is
[tex]y = \sqrt{x} [/tex]
This is the parent square root function.
If we apply the transformation;
[tex]y = \sqrt{x - k} - c[/tex]
Then the parent function will shift c units down and k units to the right.
When we the given function 3 units down and 2 units right the equation becomes:
[tex]y = \sqrt{x - 2} - 3[/tex]
Let f(x) = -2x -2. The graph of g(x) = f(x) + k is shown below. Identify the value of k.
k should be 1, Check by calculating the x values for f(x) and confronting them with g(x)
The graph of g(x) is a vertical shift of the graph of f(x) by 1 unit up. Thus, the value of k is 1.
The graph of g(x) = f(x) + k is a vertical shift of the graph of f(x) by k units. We can see from the graph that the graph of g(x) is shifted up by 1 unit relative to the graph of f(x).
Therefore, the value of k is 1.
To confirm this, we can plug in a point on the graph of g(x) into the equation for g(x) and solve for k.
For example, we can see that the point (-1, 2) is on the graph of g(x). Plugging this point into the equation for g(x), we get:
2 = -2(-1) - 2 + k
2 = 0 - 2 + k
k = 2 + 2
k = 4
However, we know that this cannot be the correct answer, because the graph of g(x) is shifted up by 1 unit relative to the graph of f(x). Therefore, the only possible value of k is 1.

B 122
C
D

155
Answer:
D
Step-by-step explanation:
10x - 5 and 7x + 4 are vertical angles and congruent, hence
10x - 5 = 7x + 4 ( subtract 7x from both sides )
3x - 5 = 4 ( add 5 to both sides )
3x = 9 ( divide both sides by 3 )
x = 3
7x + 4 and y are same side interior angles and are supplementary, thus
y + 7x + 4 = 180 ← substitute x = 3
y + 21 + 4 = 180
y + 25 = 180 ( subtract 25 from both sides )
y = 155 → D

Help me find Train A's speed speed in miles per hour pleaseeeee
Answer: it should be 25.
Step-by-step explanation: this is because the slope of the line is 25. you can see that because, when finding the slope, you see that it goes up 50 and over 2. 50/2 (rise/run) is 25.
Answer:
25
Step-by-step explanation:
On the graph, you can see the train has traveled from 0 to 150 miles (the Y-axis), and it did that in 6 hours (X-axis).
That means that it traveled 150 miles in 6 hours.
A speed is a distance divided by a time (like miles/hour). So, to get the speed, we need to divide the distance traveled by the time it took to do it:
S = 150 miles / 6 hours = 25 miles per hour

Question 35
Any four vertices of a regular pentagon will form a parallelogram. This is because the internal angles and lengths are such that selecting any four vertices will always result in the formation of a closed, opposite sides being equal, and opposite angles being equal shape, which is a parallelogram.
Question 36
If two circles touch, the point of contact lies on a straight line. Hence, the correct answer is a straight line.
Question 37
The domain of the relation R where R = {(x,y): y = x + x ; x ≥ 0 and x < 9} will be as follows: we are given that y = x + x^2 and x ranges from 0 (inclusive) to 9 (exclusive). Thus, the possible values for x within these constraints are all integers from 0 to 8. Therefore, the correct domain is
{0, 1, 2, 3, 4, 5, 6, 7, 8} and correct option is d. None
Question 38
If Mary's share is Rs. 225 and it is divided between Mary and David in the ratio 3:2, we first find the portion that represents Mary’s share. Here, Mary’s share is 3 parts and David’s is 2 parts. Together, their shares add up to 5 parts. If 3 parts equate to Rs. 225, then 1 part is Rs. 75. The total amount of money, which is 5 parts, will be 5 * 75 = Rs. 375. Hence, the correct total is Rs. 375.
Question 39
The angle between the vectors 2î + 3ĵ + k and 2î - 3ĵ - k can be found using the dot product formula.
The dot product of A and B, A.B = |A| |B| cos θ. First, compute A.B:
A = 2î + 3ĵ + kB = 2î - 3ĵ - kA.B = (2)(2) + (3)(-3) + (1)(-1) = 4 - 9 - 1 = -6Next, find |A| and |B|:
|A| = √(([tex]2^2) + (3^2) + (1^2)[/tex]) = √(4 + 9 + 1) = √(14)|B| = √(([tex]2^2) + (-3^2) + (-1^2[/tex])) = √(4 + 9 + 1) = √(14)Therefore,
cos θ = A.B / (|A| |B|) = -6 / (√(14) × √(14)) = -6 / 14 = -3 / 7Taking the inverse cosine:
θ = [tex]cos^(-1) (-3 / 7)[/tex]The approximate answer to the angle is around 116 degrees. However, because most multiple-choice sets would give their answers in radians, you would need to adjust accordingly. None of the provided answers exactly match this calculated result, therefore correct option is d. None
