Answer:
Yes, there enough tubes for each student to make their rocket.
Step-by-step explanation:
Given - In a course of 37 students they propose to make a rocket with recycled material, in order to make the rockets, in the course there are 151 cardboard tubes that were collected in a recyclable day.
To find - If 4 cardboard tubes are needed to make a rocket, are there enough tubes for each student to make their rocket ?
Proof -
Given that,
1 rocket is made with 4 cardboard tubes
Total cardboard tubes = 151
Now,
1 student will make 1 rocket
Total students = 37
⇒Total rockets made by the course = 37
Now,
1 rocket used 4 cardboard tubes
⇒37 rocket used 37×4 cardboard tubes
⇒37 rocket used 148 cardboard tubes.
As
148 < 151
⇒There are enough tubes for each student to make their rocket.
If the line segment at right is subdivided
into equal parts, what is the length of
the marked portion of the line?
75
Answer:
50
Step-by-step explanation:
75 dived into 3 parts can also be written as 75/3. 75/3 is 25 making each part worth 25. 2 segments are included in the marked portion so its 50 or (25 + 25)
The number of bacteria can be represented by the equation A(t)=200(.75)^t, wherr A(t) is the amount of bacteria in grams and t is the number of days. a. Is this function growth or decay? b. What percent is the bacteria decreasing by each day? c. How many grams of bacteria will there be in 1 week? d. After how many days will there be half the initial amount of bacteria left?
Answer:
Step-by-step explanation:
a. This is a decay function, since the final value (A) gets smaller and smaller as the days pass by.
b. The bacteria is decreasing by 75% per day exponentially.
c. In order to calculate the amount of bacteria in a week we simply substitute the variable t for 7 (7 days in a week) and solve for A
A = 200(0.75)^7
A = 26.7 bacteria after 1 week
d. In order to calculate this we need to substitute the variable A with 100 and solve for t
100 = 200(0.75)^t ... divide both side by 200
0.5 = 0.75^t
[tex]\frac{ln(0.5)}{ln(0.75)}[/tex] = t
2.4 = t
It will be half the initial amount after 2.4 days.

Answer:
x = 0.5, 2
[or 1/2, 2 if you want in fractions)
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Answer:
x=2
X=1/2 or 0.5
Step-by-step explanation:
First of all , i transfer every thing that was in the right side to the left side of equation and put 0 instead of them , then factor the new equation out by grouping them .

A quadratic in factored form is given as (x + 5) (2x - 3) = 0, what are the solutions of this given equation?
X = and x =
Answer:
x = -5, x = 1.5
Step-by-step explanation:
If the two expressions multiplied together is 0, that means that one of the expressions would have to equal 0. This gives us two possible answers. Our two equations are now:
x + 5 = 0
2x - 3 = 0
We will first solve the first one!
To isolate x, we subtract 5 from both sides to get:
x = -5
Onto the second one!
We begin to isolate x by adding 3 to both sides.
2x = 3
Now we divide both sides by 2.
x = 3/2 or 1.5

someone please tell me how to work out this type of problem i completely forgot
Answer:
Plug the x-values into the equation to get the y values. This will give you coordinates that you can graph a line with.
Step-by-step explanation:
For x = -5: y = -3 - 2 * (-5) = 7, so the coordinates are (-5, 7)
For x = -2: y = -3 - 2 * (-2) = 1, so the coordinates are (-2, 1)
(Etc.)
Then, plot these coordinates and draw a line through them to complete the graph.

[tex]\huge\boxed{\sf tan \ 28 = x / 14}[/tex]
Step-by-step explanation:
Since opposite and adjacent is given, we will use tan as trigonometric ratio.
Hence,
opposite = x , adjacent = 14 and [tex]\theta[/tex] = 28
So,
[tex]\sf tan \theta = opposite / adjacent[/tex]
tan 28 = x / 14

Graph the following exponential function given the table of
values.
Answer:
D
Step-by-step explanation:
Here, we want to select the graph of the given exponential function values
Let us take a look at the y-intercept
At the y-intercept, the value of x is 0
The y-intercept for this particular equation is 1
This mean that the y-intercept value is 1
hence, the graph will touch the y-axis at the point y = 1
looking at the graphs , only the graph D provides this, and that should be our answer

I did test
The volume of a square pyramid with a base area of 36 and a height of 9 cm is 108 cm. The correct option is B.
What is pyramid?A pyramid is a polyhedron with triangular faces that meet at a common vertex and a polygonal base.
The name of the pyramid is determined by the shape of the base. A pyramid with a square base, for example, is called a square pyramid; a pyramid with a triangular base, a triangular pyramid; and so on.
The formula to find the volume of a square pyramid is given by:
V = (1/3) x base area x height
Substituting the given values, we get:
V = (1/3) x 36 x 9
V = 108
Thus, the correct option is B.

Which is the correct solution to the cubic equation,
3/ 3x-2=1
-3
-1

3
Answer:
x = 1
Step-by-step explanation:
[tex]\sqrt[3]{3x - 2} = 1[/tex] Cube both sides of the equation
3x - 2 = 1
3x = 3
x = 1
Check: [tex]\sqrt[3]{3(1) - 2} = \sqrt[3]{3 - 2} = \sqrt[3]{1} = 1[/tex] Since x = 1 makes the original equation true, then x = 1 is the solution.
The correct solution for the given equation is x = 1.
What is an equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given is a cubic equation, [tex]\sqrt[3]{3x-2}[/tex] = 1
Solving for x,
[tex]\sqrt[3]{3x-2}[/tex] = 1
Cubing both the sides,
([tex]\sqrt[3]{3x-2}[/tex])³ = 1
3x - 2 = 1
3x = 3
x = 1
Hence, the correct solution for the given equation is x = 1.
