Answer: 4 pounds of wooden blocks and 6 pounds of plastic bricks should be used.
Step-by-step explanation:
Let x = Quantity of wooden blocks.
y = Quantity of plastic bricks.
As per given , we ahve
5x+10y=80 (i)
x+y=10 (ii)
Multiply 5 on both sides of (ii), we get
5x+5y=50 (iii)
Eliminate (i) from (iii), we get
5y=30
⇒ y= 6
Put y=6 in (ii), we get
x+6=10
⇒ x= 10-6= 4
Hence, 4 pounds of wooden blocks and 6 pounds of plastic bricks should be used.
If 5, 8 are two adjacent terms in an arithmetic sequence (in that order), then the next term is
Answer:
11
Step-by-step explanation:
Given that:
Two adjacent terms of an arithmetic sequence are given as 5, 8.
To find:
The next term = ?
Solution:
First of all, let us learn about an arithmetic sequence and its property.
An Arithmetic sequence (sometimes known as Arithmetic Progression or an AP), is a sequence in which there is a common difference between every two terms.
Suppose, an arithmetic sequence is:
[tex]a, b, c, d[/tex]
Then common difference = [tex]b-a=c-b=d-c[/tex]
Let the next term in the given sequence be [tex]x[/tex].
Then as per the property of an Arithmetic sequence, we can say:
[tex]8-5=x-8\\\Rightarrow x=3+8\\\Rightarrow x =\bold{11}[/tex]
Therefore, the answer is: 11
A game board consists of 64 squares that alternate in color between black and white. The figure below shows square $P$ in the bottom row and square $Q$ in the top row. A marker is placed at $P$. A step consists of moving the marker onto one of the adjoining white squares in the row above. How many 7-step paths are there from $P$ to $Q$ ? (The figure shows a sample path.)
9514 1404 393
Answer:
A) 28
Step-by-step explanation:
Of the seven moves, 3 must be to the left, and 4 must be to the right. That is, we end up exactly one space right of where we started, so there must be exactly one more move to the right than to the left.
The number of permutations of LLLRRRR is 7!/(4!·3!) = 35. Of those, several must be eliminated, because they result in a path that goes off the right side of the board.
The discounted sequences are ...
LRRRRLLRLRRRLLRRLRRLLRRRLLLRRRRLLRLRRRLRLLRRRRLLL"With these 7 possibilities eliminated from the list, there are 35 -7 = 28 possible paths from P to Q.
Can someone show an example of Inverses of Functions
Because I do not understand that subject
Answer:
I believe you mean algebra and inverses when you change it to solve inequalities.
Step-by-step explanation:
Let's use -3 + 4 as an example. In order to change the function, you will switch the sign. (In this case, we change "+" into ")
At this same time, you must change the sign in front of the numbers. (Positive signs become negative and negative signs become positive.
So, -3 + 4 is the same thing as 3 - -4.
3 - 4 = -1
-3 + 4 = 1
Tip: When subtracting a negative number, the answer is likely to go up instead of down.

ok so ik that the answer is 22 I think but I wanted to know how to set the answer up.
Answer:
22
Step-by-step explanation:
When youre trying to find a fraction of a number, you can divide the number by the fraction.
For instance:
1/3 of 66: 1/3 × 66 = 22
1/2 of 66: 1/2 x 66 = 33

six notebooks cost 720- Find
the cost of 5 notebooks
Answer:
$600
Step-by-step explanation:
first, you need to find the unit price which is found by dividing 720 by 6.
so, 720/6 is 120
then, to find the cost of 5 notebooks, you just need to multiply 120 by 5
which would get you 600.
therefore, the total cost of 5 notebooks is $600.
i hope that helps :)
Answer:
600
Divide 720 from 6
= 120
120 x 5 = 600
the area of a face of a cube is 144cm^2 . find its volume
Step-by-step explanation:
1 face area = length x width (aka length x length since cube)
therefore 1 side = ±√144 cm = 12 cm or - 12cm (rej as length > 0cm)
volume = length x width x height = 12 x 12 x 12 = 1728cm^3

If 1/2 cup of white sugar is needed for one batch of oatmeal raisin cookies, how much white sugar is needed for 8 batches of cookies?
Answer:
4 cups
Step-by-step explanation:
For one batch of cookies you'll need 1/2 cup of sugar. 8 batches of cookies is 8 times the amount of batches of one batch of cookies. So, if the amount of batches is multiplied by 8, then we need to multiply the amount of sugar by 8 as well:
1/2 * 8 = 8/2 = 4/1 = 4
4 cups of white sugar are needed for 8 batches of cookies.

Answer:
Step-by-step explanation:
1. You have a ladder that is 10 feet tall and you place it on the ground 6 feet away from your house, which you plan to paint. How far up will the ladder reach? (Ans: 8 feet)
2. I think drawing a diagram of this is pretty self-explanitory. Just remember to lable the ladder as 10 feet, the ground as 6 feet, and the house as 8 feet.
3. There wasn't really an equation in the question, but if you draw a triangle you'll need to solve for the third side. It would be 8 feet, but if you consider the pythagoran therom:
100ft(c^2, the hypotenuse, or the ladder)- 36 ft(a^2, or the ground)= 64, the square root of 64 would give you 8. You can write it out symbolically, but I'm typing and there's not much I can do on here.

The table and equation represent different linear relationships. Which one has the greater rate of change? Explain your reasoning.
Answer:
The equation y=4x-1 has a greater rate of change
Step-by-step explanation:
to find rate of change for the table, you use [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
so, [tex]\frac{-5-(-7)}{-2-(-3)}[/tex] = [tex]\frac{2}{1}[/tex] = 2
So the rate of change for the table is 2 while the rate of change for the equation is 4. 4>2 so the equation has a greater rate of change.

Colton's Gym charges an initiation fee of
$40 plus a monthly fee of $50. Which
of the equations below shows the cost
c of joining the gym for m months?
O c = 50 + 40m
O c = 40 + 50m
C + 40 - 50m
Answer:
c = 40 + 50m
Step-by-step explanation:
40 is a constant, it is not affected by the number of months the person works out at the gym for.
There is a monthly fee of $50. So, every month Colton gets charged $50, so this is the variable.
The total cost would be represented by the equation c = 40 + 50m then.
Let's look at this using a number for m.
If Colton went to the gym for 2 months then we can set up the equation like this:
c = 40 + 50(2)
c = 40 + 100
c = 140
Therefore he spends a total of $140 for 2 months.

BRAINLIEST WILL BE MARKE FOR THE BEST ANSWER GIVEN
Answer: Yes
Step-by-step explanation:
The Vertical angle would show that 2 of the angles are exactly the same. Its also given 2 lines that are marked as congurent. Since we know that angle and the lines are congruent we can also say that angle IFJ is congruent to angle IHG meaning that they are congruent because of ASA (Angle Side Angle Theorem)
Congruent triangles have equal corresponding sides lengths and angle measures.
The triangles are congruent by ASA
From the attached figure, we have:
[tex]\mathbf{HI \cong IF}[/tex]
Lines HG and JF are parallel lines.
It means that:
Angles G and F are corresponding, and also angles at I in both triangles are vertical angles.
So, we can conclude that both triangles are congruent by ASA

A charter airline finds that on its Saturday flights from Philadelphia to London all 180 seats will be sold if the ticket price is $200. However, for each $3 increase in ticket price, the number of seats sold decreases by one. (a) Find a formula for the number of seats sold S if the ticket price is P dollars.
Answer:
[tex]S = -\dfrac{1}{3}P+\dfrac{740}{3}[/tex]
Step-by-step explanation:
Given that:
Number of seats sold is 180 with ticket price $200.
Number of seats decreases by one when the ticket price is increased by $3.
To find:
The formula for the number of seats sold (S) when the ticket price is P dollars.
Solution:
It is linear dependency of number of seats sold, S on ticket price, P.
[tex]S\propto P[/tex]
It can be written as:
[tex]S = kP+C[/tex]
Where [tex]k[/tex] is the constant of proportionality and
[tex]C[/tex] is a constant.
Now, putting the given values:
[tex]180 = 200k +C ..... (1)[/tex]
[tex]179 = 203k+C[/tex] ...... (2)
Subtracting (1) from (2):
[tex]3k = -1\\\Rightarrow k =-\dfrac{1}{3}[/tex]
Putting the value in (1):
[tex]\Rightarrow C = 180+\dfrac{200}{3} = \dfrac{740}{3}[/tex]
Therefore the equation becomes:
[tex]S = -\dfrac{1}{3}P+\dfrac{740}{3}[/tex]
