Step-by-step explanation:
The dashes on the sides of the triangles mean that they are equal in length.
Isosceles triangle: 2 sides of equal length
Equilateral triangle: 3 sides of equal length
Triangle a doesn't have any dashes, so all the sides are different length.
Triangle b has 2 sides that each have the same number of dashes, so these sides are equal in length → Isosceles triangle
Triangle c has 2 sides that each have the same number of dashes, so these sides are equal in length → Isosceles triangle
Triangle d has 3 sides that each have the same number of dashes, so these sides are equal in length → Equilateral triangle

A number has three digits: 1, 4, and 1.
To the nearest hundred, the number rounds to 400. What is the number?
Answers
Answer:
411
Step-by-step explanation:
Because it has a 4 , 1 , and a 1
meaning the first number can't be 1 so it is automatically a 4.
and then the only 2 numbers left is 2 one's so you have to put them in their also automatically and 4 is asking 1 to round up can it.
411 can't round up,it would round down because 1 is 4 and below so it can't go up and goes down.
so 4 1 1 can't go up the number would have to be 450 to go to 500 but because it is 411 it goes down to 400 because it is rounded to 400.

Write an exponential function y = abx whose

Answers
Answer:
[tex]2(3) {}^{x} [/tex]
Step-by-step explanation:
[tex]y = ab {}^{x} [/tex]
We know that when x=1, y=6
[tex]6 = a {b}^{1} [/tex]
x=2, y=18
[tex]18 = a {b}^{2} [/tex]
Notice that if we divide
[tex] \frac{ {ab}^{2} }{ab} = b[/tex]
So if we divide 18 and 6, that will give us our common ratio.
[tex] \frac{18}{6} = 3[/tex]
So our common ratio is 3.
So know we have
[tex]a(3) {}^{x} [/tex]
Plug in one of the points to find a.
[tex]6 = a(3)[/tex]
[tex]a = 2[/tex]
So the equation. we have

Abby earns a monthly salary of $3462 plus 2% commission. Last month, she sold
$5,250 worth of products. What was her gross pay?
Answers
Find 2% of what she sold by multiplying the amount she sold by 2%:
5250 x 2% = 5250 x 0.02 = $105
Now add that to her monthly salary:

In 1949, the inflation rate in the United States was -2%If a car cost $1500 at the beginning of the year, what did it cost at the end of the year
Answers
Based on the inflation rate in the United States in 1949, the cost of the car at the end of the year would be $1,470.
What is the cost of the car at year's end?The cost can be found by the formula:
= Cost x (1 + inflation rate)
The inflation rate is negative so solving gives:
= 1,500 x (1 - 2%)
= $1,470

Solve completely \large x^4-4=x^3+2x
Answers
Move everything to one side and factorize by grouping.
x⁴ - 4 = x³ + 2x
x⁴ - x³ - 2x - 4 = 0
(x⁴ - 4) - (x³ + 2x) = 0
(x² - 2) (x² + 2) - x (x² + 2) = 0
(x² - x - 2) (x² + 2) = 0
(x - 2) (x + 1) (x² + 2) = 0
Then
x - 2 = 0 or x + 1 = 0 or x² + 2 = 0
x = 2 or x = -1 or x² = -2
If x is real, then the third case has no solution. Then x = 2 or x = -1. Otherwise, we can solve over the complexes and include x = ± √2 i where i = √(-1).

which is like a radical to ^3 to the square root of 54 after simplifying
Answers
Answer:
The radical that is equal to ∛54 is 3∛2.
Step-by-step explanation:
Given
∛54
We need to find the radical that is similar to ∛54, we need to break down the radicand 54, into smaller numbers, therefore, take the LCM of the number,
54 = 2 x 3 x 3 x 3
As we are taking the cube root, therefore, we need numbers that are repeating thrice.
Thus, the radical can be written as,
[tex]\sqrt[3]{54} =\sqrt[3]{2x 3x 3x 3} \\\\\sqrt[3]{54} =3\sqrt[3]{2}[/tex]
Hence, the radical that is equal to ∛54 is 3∛2
Answer:
[tex]3\sqrt[3]{2}[/tex]
Step-by-step explanation:
Original expression:
[tex]\implies \sqrt[3]{54}[/tex]
Factorize 54 using prime factorization:
[tex]\implies \sqrt[3]{2 \cdot 3^3}[/tex]
Apply radical rule: [tex]\sqrt[n]{ab} =\sqrt[n]{a} \cdot \sqrt[n]{b}[/tex]
[tex]\implies \sqrt[3]{2} \cdot \sqrt[3]{3^3}[/tex]
Apply radical rule: [tex]\sqrt[n]{a^n} =a[/tex]

You have to make a variable on the both side
So.....
8a-3a = 3a+25-3a
And then solve it. So the last thing you will have is
5a = 25
If you want to the simplest form...divide 25 with 5

Answer:
113.04
Step-by-step explanation:
The area of the square is 144 which means the length of each side of the square is 12. When the length on one side is 12 the radius of the circle will be half of the whole length. In this case, it means the radius is going to be 6. When we find the radius, we can use the formula r^2pie to find the area for the circle.
6 * 6 * 3.14
= 113.04
Answer:
Area = 113.04 in²
Step-by-step explanation:
Given:
Area of the square = 144 in²Area of a square
[tex]\sf A=s^2\quad \textsf{(where s is the side length)}[/tex]
Substitute the given area of the square into the formula and solve for s:
[tex]\begin{aligned}\sf A & = \sf s^2\\\implies \sf 144 & = \sf s^2\\\sf \sqrt{144} & = \sf \sqrt{s^2}\\\sf 12 & = \sf s\\\implies \sf s & = \sf 12\:\:inches\end{aligned}[/tex]
From inspection of the given diagram, the side length of the square is equal to the diameter of the circle. Therefore, the diameter is 12 inches.
Radius of a circle
[tex]\sf r = \dfrac{1}{2}\:d\quad \textsf{(where d is the diameter)}[/tex]
Substitute the found diameter into the formula and solve for r:
[tex]\begin{aligned}\sf r & = \sf \dfrac{1}{2}\:d\\\implies \sf r & = \sf \dfrac{1}{2}(12)\\\sf r & = \sf 6\:\:inches\end{aligned}[/tex]
Area of a circle
[tex]\sf A= \pi r^2 \quad \textsf{(where r is the radius)}[/tex]
Substitute the found radius into the formula and solve for A:
[tex]\begin{aligned}\sf A & = \sf \pi r^2\\\implies \sf A & = \sf 3.14 \cdot 6^2\\& = \sf 3.14 \cdot 36\\& = \sf 113.04\:\: in^2\end{aligned}[/tex]

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.
A sum of money is divided between Laura and Joan in the ratio 2:3.
Laura’s share is $8.
Let J be the amount of Joan's share and L be the amount of Laura's share.
Then the amount of Joan's share will be
L / J = 2 / 3
8 / J = 2 / 3
By the cross multiplication, then the equation will be
2J = 8 x 3
2J = 24
J = 24 / 2
J = $12
The amount of the Joan's share will be $12.
