Clare made an error when solving – 4x + 3 < 23.
Describe the error that she made.
- 4x + 3 =23
- 4x < 20
Step-by-step explanation:
-4x + 3 < 23
-4x < 20
x > -5
hmm,I don't think we need to put equal sign instead of (<) , for when we started calculating.
we can just keep the question as it is and calculate.
The error Clare made in solving the inequality -4x + 3 < 23 is in the last step. The correct solution should be x > -5, not x < -5.
When dividing or multiplying both sides of an inequality by a negative number, the direction of the inequality symbol should be flipped. In this case, since we are dividing by -4, which is negative, the inequality should be reversed.
The correct steps to solve the inequality are as follows:
-4x + 3 < 23
Subtract 3 from both sides:
-4x < 20
Divide both sides by -4 (remembering to flip the inequality symbol):
x > -5
Therefore, the correct solution is x > -5, indicating that x is greater than -5, not less than -5 as Clare mistakenly wrote.

I need help with biconditinal statements in geometry
[tex]\huge\underline\mathcal\pink{₳₦₴₩ɆⱤ:-}[/tex]
Biconditional statements do not use the key words 'if' and 'then.' Biconditional statements are true statements that combine the hypothesis and the conclusion with the key words 'if and only if.'
For example, the statement will take this form: (hypothesis) if and only if (conclusion). We could also write it this way: (conclusion) if and only if (hypothesis). If you figured out that both the conditional and converse statements have to be true for a biconditional statement to exist in geometry, you are correct. It's like a reversible jacket; you can wear it on both sides.
Let's rewrite our last example:
Conditional statement: If a polygon has three sides, then it is a triangle.
Converse statement: If a polygon is a triangle, then it has three sides.
Since both are statements are true, we can go ahead and make our biconditional statements:
A polygon is a triangle 'if and only if' it has three sides.
A polygon has three sides 'if and only if' it is a triangle.
Since we can write two biconditional statements, we could also define them as compound statements, since both the conditional and the converse statements have to be true. Let's practice some more.
Follow me❤The sets of numbers 3, 4, 5, and 8, 15, 17 are Pythagorean triples. Use what you know about the Pythagorean Theorem and explain or show why they are Pythagorean triples. Be sure to show your work for each set of triples!
Answer:
Pythagorean Theorom: a^2+b^2=c^2

Answer:
a=9/100 b= 7/20
Step-by-step explanation:
For a all you do is take the 9 out of the 100 in 1.
For b, all you do is take the 35/100, and then simplify it, so in this case it is 7/10 if you divide both the numerator and denominator by 5.
So a = 9/100 and b = 7/20

Oliver's Flavored Popcorn comes in cylindrical tins divided into three equal sections of caramel, cheese, and buttered flavors. If the tin is 10 inches in diameter and 15 inches tall, what is the volume to the nearest tenth of only the cheese popcorn?
Answer:
The volume of only the cheese popcorn is 392.5 cubic inches.
Step-by-step explanation:
To determine the volume of only the cheese popcorn,
First, we will determine the volume of the cylindrical tin
The volume of a cylinder is given by
V = πr²h
Where V is the volume of the cylinder
π is a constant, (Take π = 3.14)
r is the radius of the cylinder
and h is the height of the cylinder
From the question, the tin is 10 inches in diameter and 15 inches tall.
Diameter = 10 inches, therefore, we can find radius
Radius = Diameter/2 = 10/2 = 5 inches
r = 5 inches
h = 15 inches
Now, putting the values into the equation, we get
V = 3.14 × 5² × 15
V = 1177.5 cubic inches
This is the volume of the cylindrical tin.
Since the cylindrical tin is divided into three equal sections of caramel, cheese, and buttered flavors, then the volume of only the cheese popcorn will be one-third of the total volume of the cylindrical tin.
∴ The volume of only the cheese popcorn = 1/3 × 1177.5 = 392.5 cubic inches
Hence, the volume of only the cheese popcorn is 392.5 cubic inches.

If there are exactly 2.54 centimeters in 1 inch, how many inches are in 1 centimeter
Round to two decimal places.
===============================

Hannah wants to buy a $540 camera. She can save $40 each week from her paycheck. However, before Hannah can buy the camera, she must give her brother $60 that she owes him. For how many weeks will Hannah need to save before she can pay back her brother and buy the camera?
Answer:
w = 12
Step-by-step explanation:
Create formula:
540 = 40w - 60 where 540 is the cost of the camera, 40 is the amount saved, w is the number of weeks, 60 is the amount owed
Solve for w
540 = 40w - 60: subtract 60
480 = 40w: divide by 40
w = 12
what is the gradient and vertical axis intercept of the linear equation y = 5x + 30
Gradient = Slope = coefficient of x
Thus ;
Gradient = Slope = 5
_________________________________
Vertical axis = y -axis
To find the y-intercept of the equation we must put zero instead of x .
Let's do it.....
[tex]y = 5x + 30[/tex]
[tex]y = 5(0) + 30[/tex]
[tex]y = 30[/tex]
So the y-intercept is 30 .

Label the following numbers as rational or irrational
Answers:
a) rationalb) rationalc) rationald) irrationale) rationalEverything is rational but choice D
=======================================================
Explanation:
A rational number is anything in the form p/q where p and q are integers. The value of q cannot be zero.
So that's why -4/11 is rational. Here we have p = -4 and q = 11.
Any terminating decimal is rational. For choice A, we have 3.14 = 314/100
Choice C is also rational because [tex]\sqrt{\frac{4}{9}} = \frac{\sqrt{4}}{\sqrt{9}} = \frac{2}{3}[/tex]
Choice E is rational since 6 = 6/1.
In short, choices A, B, C, and E are rational.

10) if the pattern indicated below is continued, what would be the total number of cubes in the 5th stage
of the pattern?
a) 55
b) 36
c) 45
d) 30
Answer:
Option A. 55
Step-by-step explanation:
From the diagram given above, we discovered that the number of cubes in each stage is simply the addition of the squares of the number from 1 to the stage number i.e
1st Stage = 1² = 1 cube
2nd Stage = 1² + 2² = 1 + 4 = 5 cubes.
3rd Stage = 1² + 2² + 3² = 1 + 4 + 9
3rd stage = 14 cubes
With the above idea in mind, we can obtain the number of cubes in the 5th stage as illustrated below:
5th stage = 1² + 2² + 3² + 4² + 5²
5th stage = 1 + 4 + 9 + 16 + 25
5th stage = 55 cubes
Thus, there are 55 cubes in the 5th stage.
John is mixing paint so that he can update his apartment. He combines 7L of white paint with 3300 milliliters of blue paint. He uses 1 ½ L of paint to paint a hallway. a) What is the total combined paint? b) How much paint was left after painting? 4.
Answer:
(a) The total combined paint is 10.3L
(b) 8.8L paint was left after painting
Step-by-step explanation:
From the question, John combines 7L of white paint with 3300 milliliters of blue paint.
First, convert to the same unit, say liters, L.
Now, we will convert 3300 milliliters to liters (L)
{NOTE: 1000 milliliters (mL) = 1 liter (L)}
Since 1000 milliliters = 1 liter
∴ 3300 milliliters = 3300/1000 liters = 3.3 liters
Hence, 3300 milliliters = 3.3 L
Therefore, he combines 7L of white paint with 3.3L of blue paint.
(a) The total combined paint is 7L + 3.3L = 10.3L
∴ The total combined paint is 10.3L
(b) To determine how much paint was left after painting,
From the question, he uses 1 ½ L of paint to paint a hallway, that is, he uses 1.5 L of paint to paint a hallway;
The paint left will be 10.3L - 1.5L
10.3L - 1.5L = 8.8L
Hence, 8.8L paint was left after painting

the area of a circle is 144 π cm2 what is the diameter of the circle
Step-by-step explanation:
Area = pi × r²
144 pi cm² = pi × r²
144 pi ÷ pi = r 2
root 144 = r
12 cm = r
diameter = 2r = 2(12) = 24 cm
