The Least Significant Digit Place, or LSD, is the digit with the least value in a string of numbers.

In 0.1030, there are 4 different significant places. 0.1030

For 0.1030, the least valuable digit place is the 0.1030. This is because this numeral appears at the end of the string, and is the least valuable.

Answer:

a. 72 cm

b. 12 cm

c. 144

Step-by-step explanation:

a. Perimeter is addition of all the sides so, 12 + 12 + 12 + 12 + 12 +12= 72.

b. Apothem is the length from the midpoint to a side so, it is 12.

c. Area is base times height so, 12 times 12 equals 144.

Answer:

possibility 1 - triplet:3, mother/father:35

possibilty 2 - triplet:1, mother/father:38

 Two possibilities for the family's ages are the (father 38, Mother 38, and triplets 1-year-old each) and the second possibility is (the father and mother 35 each and triplets 3 years old each).

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.

Given here, the father and the mother have identical age and also triplets.

let the age of mother and father be x and the triplets be y then we can form the equation is 2x+3y=79

Possibility 1)                          76   3 =79

Possibility 2)                       70    9 =79

In possibility one x=38 and y =1 and possibility 2 x=35 and y=3

Hence the two possibilities are  the (father 38, Mother 38, and triplets 1-year-old each) and the second possibility is (the father and mother 35 each and triplets 3 years old each).

Answer:

D

Step-by-step explanation:

This is a rectangular prism. The volume of a rectangular prism can be found using:

v=l*w*h

For this aquarium, the length is 36 inches, the width is 12 inches and the height is 24 inches. Substitute 36 in for l, 12 for w and 24 for h.

v=36*12*24

Multiply all the numbers together

v=10,368

Volume is always units^3, because we multiply 3 numbers together. The units are inches, so the volume of the aquarium is:

Answer:

7/11

Step-by-step explanation:

Answer:

7 : 11 = 7 /11

Solution:

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 7 and 11 is 1

Divide both terms by the GCF, 1:

7 ÷ 1 = 7

11 ÷ 1 = 11

The ratio 7 : 11 cannot be reduced further by dividing both terms by the GCF = 1 :

This ratio is already in lowest terms.

Therefore:

7 : 11 = 7 /11

x = -3/5

Step-by-step explanation:

2(3 - x) -12 + 4x = -3x -9

Distribute

6 -2x -12 +4x = -3x -9

Combine like terms

2x -6 = -3x -9

Add 3x to each side

2x+3x -6 = -3x+3x -9

Add 6 to each side

5x -6+6 = -9+6

5x = -3

Divide each side by 5

5x/5 = -3/5

x = -3/5

Answer:

x=-3/5

Answer:

A

Step-by-step explanation:

Since all of the dimensions are being expanded by a scale of 1/4 of a foot to 3, or an increase of a factor of 12, the area is being increased by 12*12=144 times, or choice A. Hope this helps!

The unit rate of area in square feet of the enlargement image per square foot of the area of the original image is 144 square feet.

The scale of 1/4 of a foot = 3 feet

So scale of a foot = 3*4 =12 feet

A scale factor is a factor by which the dimension of an object is enlarged or diminished.

So, the area of the enlarged image = 12 feet*12 feet

The area of the enlarged image =144 square feet

Hence, the unit rate of area in square feet of the enlargement image per square foot of the area of the original image is 144 square feet.

Answer:

x = 9; Option C

Step-by-step explanation:

If p ║q, we are provided with the following properties;

Same Side Interior / Exterior ∠s ⇒ supplementary,

Alternate Interior / Exterior ∠s ⇒ ≅,

Corresponding ∠s ⇒ ≅

If we are focusing on the measure of two alternate interior angles, say a and b, we can assign them as such;

a ⇒ 9x + 8, and b ⇒ 15x - 46

m∠ a = m∠ b ⇒ provided they are alternate interior ∠s,

9x + 8 = 15x - 46 ⇒ Add 46 on either side of equation,

9x + 54 = 15x ⇒ Subtract 9x from either side,

54 = 6x ⇒ Divide either side by 6,

Solution; x = 9

Step-by-step explanation:

The graph which passes through the (0,0) point is the graph of f(x) = 3 sin (2x)

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The general form of a sine function is;

y = Asin(Bx+C) +D

where;

A is the amplitude.

B is the frequency.

From f(x) = 3 sin (2x), we can say that;

A = 3

This implies that the graph has waves that has height from -3 to 3.

B = 2

This means that there are two waves between 0 and 2π with the period of the function being π.

Hence, the graph goes through the (0,0) point.
