Solve for x, rounding to the nearest hundredth.
2^4x = 36
Answer:
5/4
Step-by-step explanation:
36 is the 5tf power of 2 so we can rewrite the equation as
[tex] {2}^{4x} = {2}^{5} [/tex]
Since the expressions has same base the powers must be equal to
4x = 5 and x = 5/4

Which planet in the chart is most likely Earth? Yeah
Does somone no the answer
Answer:
Kepler-452b has a probable mass five times that of Earth, and its surface gravity is nearly twice as Earth's, though calculations of mass for exoplanets are only rough estimates. If it is a terrestrial planet, it is most likely a super-Earth with many active volcanoes due to its higher mass and density.Step-by-step explanation:

Answer:
3c = t
Step-by-step explanation:
3 cereal boxes is 3c and the total is t. so 3c = t
Answer:
3c = t
3 is the amount of boxes, c is the money, therefore, it is 3c=t, which means c times the number of boxes equals t

If 48% of the students in a certain college are female and there are 2,400 female students, how many students are male?
Answer:
2,600 male students
Step-by-step explanation:
[tex]\frac{2,400}{0.48} = 5,000[/tex]
There are 5,000 students in total.
Since 2,400 of them are female, the remaining students must be male.
5,000 - 2,400 = 2,600 male students
i have i need to use the substitution method to work out what x and y is
5y−2x=10
8x+5y=60
Answer:
pick the simplest of the 2 equations
Step-by-step explanation:
5y-2x=10
5y = 2x +10
y = 2/5x + 2
now substitute
8x + 5(2/5X +2)=60
8x + 2x + 10 = 60
10x = 50
x = 5
y = 4

What is the probability of rolling an even number on the first roll of a number cube and rolling an odd number on the second roll?
Answer:
1/4.
Step-by-step explanation:
There are 3 even numbers in the 6 numbers on a cube.
So Probability first roll is even = 3/6 = 1/2.
By the same reason Probability of odd number = 1/2.
So: Probability(First is even and second is odd) = 1/2 * 1/2 = 1/4.

Select the correct answer. One factor of the polynomial 2x^3–3 x^2 - 3x + 2 is (x- 2), which expression represents the other factor, or factors, of the polynomial?
Answer:
D
Step-by-step explanation:
The factorisation of polynomial is (2x-1)(x+1). Therefore, option C is the correct answer.
The given expressions are 2x³-3x²-3x+2 and x-2.
What are factors of polynomial?The factors are the polynomials which are multiplied to produce the original polynomial.
Here, the given polynomial can be factored as follows:
x-2 |2x³-3x²-3x+2| 2x²+x-1
2x³-4x²
(-) (+)
___________
x²-3x+2
x²-2x
(-) (+)
___________
-x+2
-x+2
(-) (+)
____________
0
2x²+x-1 can be rewritten as 2x²+2x-x-1
= 2x(x+1)-(x+1)
= (x+1)(2x-1)
The factorisation of polynomial is (2x-1)(x+1). Therefore, option C is the correct answer.

Harold is designing a patio with congruent square concrete tiles. He has 72 tiles. Use grid paper to model all the possible rectangular patios Harold could build. Label the dimensions in units. Which patio has the greatest perimeter? The least perimeter?
Answer:
(a) The possible dimensions are:
1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units
(b): Patio with greatest and the least perimeter
The dimension with the greatest perimeter is: 1 by 72
The dimension with the least perimeter is: 8 by 9
Step-by-step explanation:
Given
[tex]Tiles = 72[/tex]
Solving (a): Possible rectangular models
To do this, we simply list out the possible factor pairs of 72.
So, we have:
1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units
Solving (a): Models with the least and the greatest perimeter
Perimeter (P) is calculated using:
[tex]P = 2 * (L + W)[/tex]
So:
1 unit by 72 units;
[tex]P = 2 *(1 + 72) = 146 units[/tex]
2 units by 36 units;
[tex]P = 2 *(2 + 36) = 76 units[/tex]
3 units by 24 units;
[tex]P = 2 *(3 + 24) = 54 units[/tex]
4 units by 18 units;
[tex]P = 2 *(4 + 18) = 44 units[/tex]
6 units by 12 units;
[tex]P = 2 *(6 + 12) = 36 units[/tex]
8 units by 9 units
[tex]P = 2 *(8 + 9) = 34 units[/tex]
From the calculations above:
The dimension with the greatest perimeter is: 1 by 72
The dimension with the least perimeter is: 8 by 9
