Answer:
The height of the tower = 24 units.
Explanation:
In the question above, we are given the following variables.
The total number of blocks used = 312 blocks
The bottom layer( base of the tower) = 13 blocks
We are to find how tall the tower is = height of the tower = unknown.
The total number of blocks used = Volume of the tower = 312 cubic units(blocks)
Area of the base = number of the blocks used in the bottoms layer = 13 square units( block).
Because blocks are used, we assume that this is a Rectangular based prism
The Volume of a Rectangular based prism = Area of the base × h
312 = 13 × h
h = 312 cubic units ÷ 13 square units.
h = 24 units.
There fore, the height of the tower = 24 units

Answer: 55.5 (A.)
Step-by-step explanation:
Since angle A = 29 and angle B = 41, angle C must be equal to 110
180 = m<A + m<B + m<C
180 = 29 +41 + m<C
180 = 70 + m<C
110 = m<C
Therefore, side c must be the longest, side b must be the second longest, and side a must be the shortest.
Since side length a, angle A, and angle B are known, one can use the law of sines to solve for side b.
Law of Sines: sinA/a = sinB/b = sinC/c
sinA/a = sinB/b
sin29/41 = sin41/b
b(sin29/41) = sin41
b = 41(sin41)/(sin29)
b = 55.48
b = 55.5

Au dépanneur, six conserves de maïs et deux boîtes de pâtes coûtent au plus 15,75 $. Indiquez le prix possible de la boîte de pâtes si une conserve de maïs coûte 0,50 $ de plus que la moitié du prix d’une boîte de pâtes.
Answer:
$ 2.55 or less
Step-by-step explanation:
We have if they buy 6 cans of corn and 2 boxes of pasta are priced at $ 15.75 or less, they also tell us that the price of a can of corn is $ 0.50 + half the price of a box of pasta. Let's formulate the equation, let "x" be the cost of the can of corn and "y" be the cost of the box of pasta.
6 * x + 2 * y <= 15.75
x = 0.5 + y / 2
replacing:
6 * (0.5 + y / 2) + 2 * y <= 15.75
3 + 3 * y + 2 * y <= 15.75
5 * and <= 15.75-3
y <= 12.75 / 5
y <= 2.55
replacing in x:
x = 0.5 + 2.55 / 2 = 1.775
Which means that the price of a can of corn is $ 1,775 and for the box of pasta it is $ 2.55 or less.
Answer:
The answer is 2.55

Math question need help
Answers and Step-by-step explanations:
(a)
We need to figure out the amount (or total cost) for each size candy given that they sell a certain number of each box. For the small box, we're given the cost is $4.70, while the large box is $7.00.
We buy x of the small box, so the total amount should be 4.70 * x, or just 4.70x. We buy y of the large box, so the total amount should be 7.00 * y, or just 7y.
So on the table, the top value should be 4.70x, and the bottom value should be 7y.
(b)
The total number of boxes sold was 45 boxes. Remember that x boxes were small and y boxes were large. Since the number of small boxes plus the number of large boxes is equal to the total of 45, we can write:
x + y = 45
(c)
The total cost was $269, so we can write this as the sum of the amounts that we found in part (a):
4.70x + 7y = 269
The product of two binomials, u(x) and v(x), is a binomial of degree 8 with a positive leading coefficient. What must be true about the sum of u(x) and v(x)?
Answer:
From the above conclusion, it can be inferred that sum of u(x) and v(x) is a binomial of degree 4 with a positive or negative leading coefficient depending on the value of the constant 'a'Step-by-step explanation:
If the product of two binomials, u(x) and v(x)has a binomial of degree 8, then the individual binomial will have a binomial of degree 4. For example, lets assume u(x) = ax⁴ + bx and v(x) ax⁴+cx. Note that they are both functions of x and contain only two terms since they are binomial.
Taking their product we have;
u(x)*v(x) = (ax⁴ + bx)*(ax⁴+cx)
u(x)*v(x) = a²x⁸+acx⁵+abx⁵+bcx²
it can be seen that the higest power of x is 8 which gives the degree of the product.
Taking their sum;
u(x)+v(x) = (ax⁴ + bx)+(ax⁴+cx)
u(x)+v(x) = ax⁴ + ax⁴+ bx +cx
u(x)+v(x) = 2ax⁴ + bx +cx
It can be seen that the digest power of x is 4 which gives the degree of the sum of the binomial.
From the above conclusion, it can be inferred that sum of u(x) and v(x) is a binomial of degree 4 with a positive or negative leading coefficient depending on the value of the constant 'a'

Which of the following functions shows the absolute value parent function, F(x) = |x|, vertically stretched?
A. G(x) = |x| + 9
B. G(x) = 3|x|
C. G(x) = |x + 14|
D. G(x) = 1/2|x|
Answer:
C, I believe!
The functions shows the absolute value parent function, F(x) = |x|, vertically stretched is C. G(x) = |x + 14|
What is the absolute value function?The absolute value function is defined by the following piecewise rule, depending on the input of the function:
|x| = x, x ≥ 0.
|x| = -x, x < 0.
This can be measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0, and has vertex(turning point) at (0,0). The range is from the y-coordinate of the vertex to positive infinity.
Vertex (2, 0), Range: {y | 0 ≤ y < ∞}
The parent absolute value function is F(x) = |x|,
If this function is stretched vertically, then the stretched function is of the form.
G(x) = |x + a|
where 0<a<1
Therefore the correct option is C. G(x) = |x + 14|

1. The theoretical possibility of spinning every number out of the 200 spins is approximately to the nearest whole number: 16 times. We found that by dividing 200 by 12 to see how many of each number could fit in 200. 200 divided by 12 equals 16.666 but we can't spin a number 16.6 times so we have to round it to the nearest whole number that stays in the range of 200.
2.
i. The experimental probability of spinning a 1 is 20/200 or 1/10.
ii. The experimental probability of spinning an 8 is 30/200 or 3/20.

In which figure is point G an orthocenter? Triangle A B C is a right triangle. Lines are drawn from each point to the opposite side and intersect at point G. Triangle F D E is shown. Lines are drawn from each point to the opposite side and intersect at point G. The lines cut each side into 2 equal parts. Triangle L M N is shown. Lines are drawn from each point to the opposite side and intersect at point G. Each angle has a different measure. Triangle H J K is shown. Lines are drawn from each point to the opposite side to form right angles and the lines intersect at point G.
Answer:
the Answer is D just got it right hope this help you
Step-by-step explanation:
The 4th figure is the correct option, i.e. triangle H J K, in which lines are drawn from each point to the opposite side to form right angles and the lines intersect at point G with G is an orthocentre.
What is orthocentre?The orthocenter denotes the intersection of all right angles extending from the vertices to the opposite sides, i.e. the altitudes. The term ortho means "right," and it is defined as the point at which three altitudes are drawn from the three vertices of a triangle intersect.
How to solve this problem?From the definition, it is clear that the lines must make right angles and intersect at G. The first three figures do not meet the criteria of orthocentre.
Therefore the 4th figure is the correct option, i.e. triangle H J K, in which lines are drawn from each point to the opposite side to form right angles and the lines intersect at point G with G is an orthocentre.

In a group of 35 pupils, 11 play the flute only. 8 play the piano only. 15 play neither instrument. A student is selected at random. What is the probability the student plays both instruments?
Answer: 1/35
Step-by-step explanation:
From the question, in a group that has 35 pupils, 11 of the pupils play flute only, 8 play the piano only and 15 play neither instrument.
The probability that a student plays both instruments will be:
Since a third instrument is not mentioned, P(a randomly selected student plays the flute and the piano)
35-15=20,
This is the total students minus the students that play neither instruments.
We then subtract those that play flute only and those that plays piano only from 20. This will be:
20-11-8 = 1
Probability (a student plays both instrument) = 1/35

Describe the symmetry of these functions
Answer:
line symmetry & rotational symmetry
Step-by-step explanation:
First given graphs of functions are symmetric about the y-axis while the second is not symmetric about any axis.
What is symmetry?If two figures look an exact shape but their size could be small or big then both figures are called similar figures.
When anything has identical pieces facing one another or revolving around an axis, it is said to be symmetrical.
For example, a square with a side of 10 cm and another with a side of 20 cm both square will be similar.
Given two graph of the any function.
If we look at first graph ;
If we fold it about the y-axis then it will be overlapped so it will be symmetric about the y-axis.
Now,
In the second graph; If we want to fold two portions of this graph such that both parts can overlap each other then it is not possible so it will not symmetric about any axis.
Hence "First given graphs of functions are symmetric about the y-axis while the second is not symmetric about any axis".

Either enter an exact answer in terms of m or use 3.14 for t and enter your answer as a decimal.
Answer:
251.2 units³ ; 80π units³
Step-by-step explanation:
Volume of a Cylinder is: [tex]V=\pi r^2 h[/tex]
'r' is the radius.
'h' is he height.
The cylinder has a base radius of 4 units and the height 5 units.
Using 3.14 for Pi:[tex]V=3.14*4^2*5\\V=3.14*16*5\\V= 50.24 * 5\\\boxed {V=251.2}[/tex]
The approximate volume is 251.2 units³.
