whats the least common denominator of 2/5 1/2 and 3/4?
Answer:
20
Step-by-step explanation:
Final answer:
The least common denominator for the fractions 2/5, 1/2, and 3/4 is 20, as it is the smallest number that all denominators can divide into without leaving a remainder.
Explanation:
The least common denominator (LCD) of the fractions 2/5, 1/2, and 3/4 is the smallest number that can be divided evenly by each of the denominators (5, 2, and 4, respectively). To find the LCD, we can list out the multiples of each denominator until we find a common multiple.
The multiples of 5 are 5, 10, 15, 20, 25, and so on. The multiples of 2 are 2, 4, 6, 8, 10, 12, and so on. The multiples of 4 are 4, 8, 12, 16, 20, and so on. When we look at these lists, the smallest number that appears in all three lists is 20. Therefore, 20 is the least common denominator for the fractions 2/5, 1/2, and 3/4.

? is the hypotenuse of the right triangle formed.
Using Pythagoras' identity on the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

Melissa then instructs Omkar to measure the angle between Melissa and the big rock. From his vantage point, Omkar sees an angle of 98^\circ98
∘
98, degrees between Melissa and the big rock.
What is the distance across the river from Omkar to the big rock?
Do not round during your calculations. Round your final answer to the nearest meter.
Answer:
The distance across the river from Omkar to the big rock is 72 meters.
Step-by-step explanation:
Using the given information draw as triangle as shown below.
According to angle sum property, the sum of interior angles of a triangle is 180°.
In triangle ABC,
\angle A+\angle B+\angle C=180^{\circ}
98^{\circ}+33^{\circ}+\angle C=180^{\circ}
131^{\circ}+\angle C=180^{\circ}
\angle C=180^{\circ}-131^{\circ}=49^{\circ}
The measure of angle C is 49°.
Sine formula:
\frac{a}{\sin a}=\frac{b}{\sin b}=\frac{c}{\sin c}
Using sine formula in triangle ABC, we get
\frac{AC}{\sin B}=\frac{AB}{\sin C}
\frac{AC}{\sin 33^{\circ}}=\frac{100}{\sin 49^{\circ}}
AC=\frac{100}{\sin 49^{\circ}}\times \sin 33^{\circ}
AC=\frac{100}{0.7547}\cdot0.544639
AC=72.166
AC\approx 72
Therefore the distance across the river from Omkar to the big rock is 72 meters.

What is the area of the shaded triangular section?
18 square inches
36 square inches
72 square inches
144 square inches
Answer:
The area of the shaded triangular section is 72 square inches
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The rectangular stained glass can be divided into 24 identical triangular parts
step 1
Determine the area of complete rectangle
[tex]A=(48)(36)=1,728\ in^2[/tex]
step 2
Divide the area of complete rectangle by 24
[tex]1,728/24=72\ in^2[/tex]
therefore
The area of the shaded triangular section is 72 square inches
Answer:
72 square inches
Step-by-step explanation:
The image is shown below.
The area of a rectangle is length times width.
Length is 48 and width is 36
Hence, area of whole rectangle is:
Area = 48 * 36 = 1728
Now, the whole figure is broken down into
24 congruent triangles
So, each triangle's area is:
1728/24 = 72 square inches
The shaded region is ONE of the triangles, so the shaded region area is:

A guinea pig weighs 1,130 grams.
What does the guinea pig weigh measured in kilograms?
The weight of the guinea pig measured in kilograms is A = 1.130 kg
What is unit conversion?In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.
The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.
A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.
Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.
Given data ,
Let the measurement of unit be represented as A
Now , the weight of the guinea pig = 1,130 grams
where from the unit conversion
1000 grams = 1 kg
So , weight of the guinea pig measured in kilograms A = 1,130 grams / 1000
On simplifying , we get
The weight of the guinea pig measured in kilograms A = 1.130 kilograms
Therefore , the value of A is 1.13 kg
Hence , the measurement is A = 1.13 kg

The guinea pig weight measured in kilograms is 1.13kgs.
To convert the weight of a guinea pig from grams to kilograms, you need to understand the relationship between these units:
In the metric system, 1 kilogram (kg) is equal to 1,000 grams (g).
Start with the weight of the guinea pig: 1,130 grams.
Use the conversion factor: 1,000 grams = 1 kilogram.
Divide the weight in grams by the conversion factor to find the weight in kilograms.
1,130 grams ÷ 1,000 = 1.13 kilograms.
Q3. Express 984. 6080 correct to
a. 2 decimal places _______________
b. 4 significant figures _____________
c. 3 decimal places ________________
d. the nearest hundredth___________ help
Answer:
a) 984.6080 = 984.61 to 2 decimal places
b) 984.6080 = 984.6 to 4 significant figures
c) 984.6080 = 984.608 to 3 decimal places
d) 984.6080 = 984.61 to the nearest hundredth
Step-by-step explanation:
Answers to the approximation questions above are supplied below.
First, you needs to know approximation processes:
Step 1: Keep the required number of digits in question.
Step 2: Before rounding off the remaining digits, look at the next digit to the required number of accuracy, if it is 5 or more, increase the last digit of the number you're keeping by 1, otherwise leave it as it is and round down to zero all the unwanted digits.
Similarly, there is need know the meaning of each degree of accuracy.
1. Decimal places: These are the number of digits occurring after the decimal point. E.g. a set of figures in 1 decimal place has only one digit after decimal point, i.e. 65.4. In the case of the question above,
a) 984.6080 = 984.61 to 2 decimal places
c) 984.6080 = 984.608 to 3 decimal places
2. Significant figures: Basically, these are nonzero digits in a set of figures. However, when zero is in the middle of nonzero digits, i.e, 3045, such zero is a significant figure. In the question above,
b) 984.6080 = 984.6 to 4 significant figures
3. Hundredth: Under place value system, hundredth of a set of figures is located at two digits after the decimal point. In other words, hundredth is same as two decimal places so the same approach is required for the two. Thus;
d) 984.6080 = 984.61 to the nearest hundredth
You can see that the result for both 2 decimal places and nearest hundredth are the same, that is, 984.6080 = 984.61 to 2 decimal places and to the nearest hundredth respectively.
Therefore, the answers are summarized thus:
a) 984.6080 = 984.61 to 2 decimal places
b) 984.6080 = 984.6 to 4 significant figures
c) 984.6080 = 984.608 to 3 decimal places
d) 984.6080 = 984.61 to the nearest hundredth
Answer:
984.6080
a. 2 decimal places
984.61
b. 4 significant figures
984.6
c. 3 decimal places
984.608
d. the nearest hundredth

A frog sitting on a stump 3 feet high hops off and lands on the ground.
During its leap, its height h in feet is given by h= -0.5d^2 + 2d + 3, where d
is the distance from the base of the stump. How far is the frog from the
base of the stump when it landed on the ground? *
Answer: The distance of frog from the base of the stump is 5.16 feet ( approx)
Step-by-step explanation:
Given, A frog sitting on a stump 3 feet high hops off and lands on the ground.
During its leap, its height h in feet is given by [tex]h= -0.5d^2 + 2d + 3[/tex], where [tex]d[/tex] is the distance from the base of the stump.
When the stump landed on the ground, h= 0 .
So put h=0 in the given equation , we get
[tex]0=-0.5d^2 + 2d + 3\\\\\Rightarrow\ 0.5d^2-2d-3=0[/tex]
Multiply both sides by 2 , we get
[tex]d^2-4d-6=0\\\\\Rightarrow\ d=\dfrac{-(-4)\pm\sqrt{4^2-4(1)(-6)}}{2(1)}\\\\=\dfrac{4\pm\sqrt{16+24}}{2}\\\\=\dfrac{4\pm\sqrt{40}}{2}\\\\=\dfrac{4\pm2\sqrt{10}}{2}=2\pm\sqrt{10}[/tex]
[tex]i.e.\ d=2-\sqrt{10}\ \ or\ \ d=2+\sqrt{10}\\\\\ i.e. d=2-3.1622\ \ or\ \ d=2+3.1622\\\\ i.e. d= -1.1622\ \ or\ \ d=5.1622\approx5.16[/tex]
Since , distance cannot be negative.
Hence, the distance of frog from the base of the stump is 5.16 feet ( approx).

Judy is baking a round cake for her niece's birthday and the recipe requires her to coat the bottom of the pan with flour. If the cake pan has an 8-inch diameter, what is the area that she will need to cover with flour on the bottom of the pan?
Answer:
A = 50.24
Step-by-step explanation:
Diameter = 8
8/2 = 4
4 is the radius
A = πr2
A = 3.14 x 42
4 x 4 = 16
A = 3.14 x 16
A = 50.24
