Answer: B: 8*1 = 8
Step-by-step explanation:
The identity property of multiplication says that:
There exist a number, called the identity, such that when we multiply any real number N by this identity, the result is the same number N.
The identity is 1.
then N*1 = N.
The option that is an example of that is:
8*1 = 8.
Option B

a man earns $140 in a 5 day week. what is his pay in 3 days?
Answer:
$84
Step-by-step explanation:
divide 140 by the five days and you get 28 then you multiple it by the 3 days and you get $84
His pay for 3 days would be $84.
To find the man's pay for 3 days, we can use the concept of proportionality. Since the man earns $140 in a 5-day week, we can calculate his daily earnings by dividing the weekly earnings by the number of days in the week:
Daily earnings = Weekly earnings / Number of days in the week
Daily earnings = $140 / 5 days
Now, let's calculate the daily earnings:
Daily earnings = $140 / 5 days = $28 per day
Therefore, the man's pay for 3 days would be:
Pay for 3 days = Daily earnings * Number of days
Pay for 3 days = $28 * 3 days = $84
His pay for 3 days would be $84.

The two interior angles on one lateral face of a pyramid-shaped
paperweight measure 35° each. What is the measure of the unknown
angle?
Answer:
Option (B)
Step-by-step explanation:
From the property of a triangle,
Sum of all interior angles of the triangle is 180°
By applying this property in the given triangle IHK,
m∠HIK + m∠IKH + m∠KHI = 180°
m∠HIK + 35° + 35° = 180°
m∠HIK = 180° - 70°
= 110°
Therefore, measure of the unknown angle of the given triangle is 110°.
Option (B) will be the answer.
Answer:
As eudora states: B).110 is the correct answer.
4x-1=4x+7 regroup/ divide by the number next to x
Answer:
x = ∞Step-by-step explanation:
Given the expression 4x-1 = 4x+7, we are to simplify the expression and find the value of x. To do that the following steps must be carried out.
Step 1: collect the like terms by regrouping the expression
4x-1 = 4x+7
4x - 4x = 7+1
0x = 8
Step 2: Dividing both sides by the number next to x
0x/0 = 8/0
x = ∞
Any constant dividing zero will always return infinity as a value.
In order to rescue Sela's cat, her mother propped a 19 foot long ladder against a tree at a 42° angle with the ground. How
many feet above the ground was their cat? Round your answer to the nearest tenth of a foot.
Answer:
12.7 feet
Step-by-step explanation:
To solve this question, we use the trigonometric function of Sine
sin θ = Opposite side/Hypotenuse
θ = 42°
Hypotenuse = 19 foot ladder
Opposite side = Distance of the cat from the ground(height of the tree)= unknown
sin 42° = Opposite/19 feet
Opposite = sin 42° × 19
Opposite = 12.713481521 feet
Approximately to the nearest tenth of a foot = 12.7 feet.
Therefore, the cat was 12.7 feet above the ground.

Answer:
See bolded below.
Step-by-step explanation:
Attachment 1 : The sum of all exterior angles in any regular polygon will be 360 degrees, so if an exterior angle is found to be 30 degrees, it will have 360 / 30 sides. Therefore 360 / 30 = 12 sides
Attachment 2 : This figure is a concave quadrilateral. You can tell by it's shape, but also as one interior angle, in this case ∠KLM, is greater than 180 degrees.
Attachment 3 : As you can see the missing number is simply sum of the numbers provided on the left. Therefore the missing number will be the following,
1³ + 2³ + 3³ + 4³ + 5³ = 1 + 8 + 27 + 64 + 125
= 125
Attachment 4 : This is an example of the associative property, as it allows you to re - group the numbers. Your solution will be " Associativity. "
Attachment 5 : The cube of a negative integer will always result in a negative integer. Let's take - 3 as an example,
(- 3)³ = - 3 [tex]*[/tex] - 3 [tex]*[/tex] - 3 = 9 [tex]*[/tex] - 3 = - 27

you are given the expressions 76+n and 2n + 26. What is the smallest value of n that will make each number rational?
Answer:
The smallest value of n is 5.
Step-by-step explanation:
The expressions provided are:
[tex]1. \sqrt{76+n}\\\\2. \sqrt{2n+26}[/tex]
Rational numbers are those numbers that can be expressed in ratio or fractional form, i.e. in the form of [tex]\frac{p}{q}[/tex].
The provided numbers have denominators as 1.
We need to find the minimum value of n to make both the numbers a perfect square.
Consider the first number,
[tex]\sqrt{76+n}=\sqrt{76+5}=\sqrt{81}=9[/tex]
The number [tex]\frac{9}{1}[/tex] is a rational number.
Consider the second number,
[tex]\sqrt{2n+26}=\sqrt{(2\times5)+26}=\sqrt{36}=6[/tex]
The number [tex]\frac{6}{1}[/tex] is a rational number.
Thus, the smallest value of n is 5.
Florence's Stationery sells thank-you cards in packs of 12 and birthday cards in packages of 9. Surprisingly, the store sold the same number of each type of card this month. What is the minimum number of each card type that the store must have sold?
Answer:
36
Step-by-step explanation:
The lowest number is the least common multiple of 12 and 9.
12 = 2^2 * 3
9 = 3^2
LCM = 2^2 * 3^2 = 4 * 9 = 36
Answer: 36
Write an equation in point – slope form from the line through the given point with the given slope. (-10, -1); m=-1
Answer:
y = -x - 11
Step-by-step explanation:
We know the equation must be: y = -x + c
However we do not know what "C" is. If we plug in our x and y values then we can find out the value of C.
So:
-1 = -(-10) + c
-1 = 10 + c
so c = -11
So our equation is:
y = -x - 11
(9x2 - 2x - 3) - (5x+ - X - 2)
