What’s the answer to 8 and 9
Answer: 4 red and 12 blue
Step-by-step explanation: Answer to 9
We know that for every red rose, he plants 3 blue flowers. The rate is 1:3. If he grows 16, there will be 4 red roses and 12 blue ones. This is because the rate is 1:3 then there are 4 flowers in all. This is 1/4 of how much he wants to grow. So multiply each type of plant by 4. 1 times 4 is 4, so there are 4 red ones. 3 times 4 is 12, so there are 12 blue ones. Hope this helps!

Which of the following equations has an axis of symmetry with the equation x = 3?
y=x² + 6x-3
y= 2x² + 6x-3
y=x² - 6x +3
y=3x² + 6x-3
The equation which has an axis of symmetry with the equation x = 3 as required in the task content is; y = x² - 6x +3.
Which equation among the given answer choices has an axis of symmetry; x = 3?It follows from the task content that the equation which has an axis of symmetry; x = 3 be determined among the answer choices.
By expressing the equation; y = x² - 6x +3 in vertex form; y = ( x - h )² + k; where the axis of symmetry is given by; x = h; we have that;
y = ( x - 3 )² - 6

Tyshawn took a taxi from his house to the airport. The taxi company charged a pick-up fee of $2.50 plus $3.50 per mile. The total fare was $79.50, not including the tip. Which equation could be used to determine mm, the number of miles in the taxi ride?
Answer: m = 22
Step-by-step explanation:
First, you subtract $2.50 from the total of $79.50 (because that is the static fee) to get $77.00. Now, because every mile is $3.50 and we want to find the number of miles, we divide $77 by $3.50 to get 22. (An easy way to do this mentally is to divide 77 by 7 and multiply by 2.) Therefore, m = 22.

Answer:
[tex] \sf \: 2x + 3 = 9, \: x = 3[/tex]
Step-by-step explanation:
Given statement,
→ Sum of 2 times a number & 3 is 9.
Let the unknown number be,
→ [tex] \sf \pink{x}[/tex]
Forming the equation,
→ (2 × x) + 3 = 9
→ 2x + 3 = 9
Now the value of x will be,

→ 2x = 9 - 3
→ 2x = 6
→ x = 6/2
→ [ x = 3 ]
Hence, the value of x is 3.
tree with root vertex d that has a left edge to f, a center edge to b, and a right edge to a. b has a left edge to i, a center edge to h, and a right edge to e. a has a center edge to c. c has a center edge to g. (a) give the order in which the vertices of the tree are visited in a post-order traversal. (b) give the order in which the vertices of the tree are visited in a pre-order traversal.
Answer:
post-order: f, i, h, e, b, g, c, a, dpre-order: d, f, b, i, h, e, a, c, gStep-by-step explanation:
You want the (a) post-order, and (b) pre-order list of visited vertices in a traversal of the tree described by {root, left, center, right}: {d, f, {b, i, h, e}, {a, {c, g}}}.
(a) Post-orderA tree is traversed in post-order by visiting the left branch, center branch, and right branch before the root. This is accomplished recursively.
For the given tree, the root 'd' has left branch 'f' which has no branches. That means node 'f' is reported first.
The middle branch goes to 'b' which has three branches. Those are reported before their root 'b'.
The right branch from root 'd' goes to 'a', which has branch 'c' going to 'g'. So, 'g' is reported, then 'c', then 'a'.
Finally, 'd' is reported.
Hence, the post-order traversal is f, i, h, e, b, g, c, a, d.
(b) Pre-orderThe pre-order traversal reports the root node, then the left, center, and right nodes, recursively. The vertices are effectively visited in the order in which we have defined the tree above: d, f, b, i, h, e, a, c, g.

What is the greatest common divisor?
the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, and y.
We have given,
Petal and Leaf florists currently have 30 roses, 36 carnations, and 54 tulips
Since it is given that there are 75 rose and 45 lily flowers. Therefore,
Factorise 30 as follows:
30 = 2 × 3 × 5
Factorise 36 as follows:
36 = 2 × 2 × 3 × 3
Factorise 54 as follows:
54 = 2 × 3 × 3 × 3
We know that HCF is the highest common factor.
Since the common factor between the numbers 30, 36, and 54 is 2×3=6.

Total bill = $159.67 x 1.10+ 175.637 or $175.64
$175.64 rounded to the nearest $10 dollars is $180 as the number in the 1s column is greater than 5. Because of this, you round up to get the nearest $10.
Total bill equals $180
