round 2.36 to 1 significant figure
Rounding 2.36 to 1 significant figure results in 2, as the first non-zero digit remains unchanged when the subsequent digit is less than 5.
Explanation:To round 2.36 to 1 significant figure, you look at the first non-zero digit, which is 2. Since the digit following it (3) is less than 5, the number 2 remains unchanged, and any digits after the 3 are dropped. Therefore, the number 2.36 rounded to 1 significant figure is simply 2.
To round 2.36 to 1 significant figure, we look at the digit after the first significant figure. If this digit is less than 5, we round down. If it is 5 or greater, we round up. In this case, the digit after the first significant figure is 6, which is greater than 5, so we round up. The rounded number to 1 significant figure is 2.4.

What is the value of x in 5(2x - 7)=15x-10?
3.1 Pull out like factors :
-5x - 25 = -5 • (x + 5)
4.1 Solve : -5 = 0
This equation has no solution.
A a non-zero constant never equals zero.
4.2 Solve : x+5 = 0
Subtract 5 from both sides of the equation :
x = -5
The value of x in 5(2x - 7)=15x-10 is 5
What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
Here, the Algebraic expressions with variable in x is given :
5(2x - 7)=15x-10
which is solved using properties of multiplication and solving for value x by arranging variables and constant separately aside:
5(2x - 7)=15x-10
20x - 35 = 15x -10
20x -15x = 35-10
5x = 25
x= 5
Therefore, the value of x in 5(2x - 7)=15x-10 is 5

Janet’s car insurance payment decreases by $30 each year. which expressions represent the total change in her payment, in dollars, after 44 years?
The total change in Janet's car insurance payment after 44 years is $1320.
Explanation:To find the total change in Janet's car insurance payment after 44 years, we can use the formula:
Total change = decrease per year × number of years
In this case, the decrease per year is $30 and the number of years is 44. So the expression representing the total change in her payment would be:
Total change = $30 × 44 = $1320
Therefore, Janet's car insurance payment will decrease by $1320 after 44 years.

Explanation:The task is to express the number 0.00000765 in scientific notation. Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in standard decimal form. It is commonly used in science and mathematics.
We have to determine which of the given options correctly represents this number in scientific notation.
The number 0.00000765 can be written as 7.65 times ten to the negative sixth power. This is because there are six places to the right of the decimal point before we encounter the first non-zero digit. Therefore, the correct answer is 7.65 • 10-6.

Which is not a property of all similar triangles
The lengths of the sides of a triangle are 3x, 5x – 12, and x + 20. Find the value of x so that the triangle is isosceles. ...?
Final answer:
To find the value of x for the triangle to be isosceles, we set the lengths of any two sides equal to each other and solve for x. After testing different cases, we find that x equals 10 satisfies the condition for the triangle to be isosceles.
Explanation:
For a triangle to be isosceles, at least two sides must have equal length. We're given the side lengths as 3x, 5x - 12, and x + 20. We have two cases to consider to find the value of x for the triangle to be isosceles:
Case 1: 3x = 5x - 12
Case 2: 3x = x + 20 or 5x - 12 = x + 20
To solve for x in case 1, we equate the two expressions and solve as follows:
3x = 5x - 12
2x = 12
x = 6
However, if we substitute x = 6 into the third side (x + 20), we get a length of 26, which does not equal either of the first two sides. Therefore, x = 6 does not satisfy the condition for an isosceles triangle.
For case 2, we consider 3x = x + 20:
3x = x + 20
2x = 20
x = 10
By substituting x = 10 into 5x - 12, we get 50 - 12 = 38. We can see that two sides of the triangle are 30 and 30 (since 3x equals 3(10)), confirming that the triangle is isosceles with x equal to 10.

"In ABC, mBAC = 5x + 8, mABC = 6x + 22, and mBCA = 3x 25.
A.Find the value of x.
B.Find the measure of 3. Show your work."
Actually, the answer is 12.5
5x+8+6x+22+3x+25= 180
(5x+6x+3x)+(8+22-25)= 180
14x+5=180
14x+(5-5)=180-5
14x=175
14x/14=175/14
X=12.5
Double check:
(5*12.5)+8=70.5
(6*12.5)+22= 97
(3*12.5)-25=12.5
70.5+97+12.5=180 degrees.
So, x=12.5

A cube has side length x. One side of the cube is increased by 4 inches, and another side is doubled. The volume of the new rectangular prism is 450 cubic inches. The equation 2x3 + 8x2 = 450 can be used to find x. What was the side length of the original cube? Use a graphing calculator and a system of equations to find the answer.
4 inches
5 inches
9 inches
10 inches
The length of the side of the original cube in the given scenario is 5 inches.
A cube is a three-dimensional figure with equal sides.
Given that
The length of the edge of a cube = x
Also, one of the sides is increased by 4 inches, and another side is doubled,
so, now the new dimensions are x, x+4, 2x, and the shape is a rectangular prism.
The area of the rectangular prism = 450 sq. inches
base × height × length = 450 sq. inches
x × (x + 4) × 2x = 450
2x³ + 8x² = 450
2x³ + 8x² - 450 = 0
x³ + 4x² - 225 = 0
Substitute x=5 to see that it is a root of the equation,
5³ + 4(5)² - 225 = 125 + 100 - 225 = 0
So, x - 5 is a factor of the equation,
Now,
x³ + 4x² - 225 = (x−5)(x² + 9x + 45) = 0
The roots of the quadratic equation are imaginary as
D = 9² - 4 × 1 × 45 = 81 - 180 = -99
The discriminant is negative, therefore, the roots are not real.
So, the length of the side of the original cube is 5 inches.

A conical paper cup has dimensions as shown in the diagram. How much water can the cup hold when full?
94.2 cm divided by pi which is 3.14 equals to 30 evenly hoped this helped yall out
The volume of the conical cup is approximately 94.25 cm³. This is the amount of water it can hold when full.
To find the volume of the conical paper cup, we'll use the formula for the volume of a cone:
[tex]\[ V = \frac{1}{3} \times \pi \times r^2 \times h \][/tex]
Where:
- ( V ) is the volume of the cone
- ( pi ) is a constant (approximately 3.14159)
- ( r ) is the radius of the circular base of the cone
- ( h ) is the height of the cone
Given:
- ( r = 3 ) cm (half the diameter)
- ( h = 10 ) cm
Substituting the given values into the formula:
[tex]\[ V = \frac{1}{3} \times \pi \times (3^2) \times 10 \][/tex]
[tex]\[ V = \frac{1}{3} \times \pi \times 9 \times 10 \][/tex]
[tex]\[ V = \frac{1}{3} \times 90\pi \][/tex]
[tex]\[ V = 30\pi \][/tex]
Now, let's calculate the approximate value of [tex]\( \pi \)[/tex] which is 3.14159:
[tex]\[ V \approx 30 \times 3.14159 \][/tex]
V≈94.2477
So, the volume of the conical paper cup is approximately [tex]\( 94.2477 \, \text{cm}^3 \) or \( 94.25 \, \text{cm}^3 \)[/tex] rounded to two decimal places. This is the amount of water the cup can hold when full.
