Find the least square number divisible by 5, 10, 15. (a) 100 (b) 625 (c) 900 (d) 225
Answer:-
900
Verification:-
[tex]\\ \sf\longmapsto \dfrac{900}{5}=180[/tex]
[tex]\\ \sf\longmapsto \dfrac{900}{10}=90[/tex]
[tex]\\ \sf\longmapsto \dfrac{900}{15}=6[/tex]
Answer:
a) 100
→ [tex]\frac{100}{5}[/tex] = 20
→ [tex]\frac{100}{10}[/tex] = 10
→ [tex]\frac{100}{15}[/tex] = 6⅔
100 is not divisible by 15
b) 625
→ [tex]\frac{625}{5}[/tex] = 125
→ [tex]\frac{625}{10}[/tex] = 62.5
→ [tex]\frac{625}{15}[/tex] = 41.6
625 is not divisible by 10 and 15.
c) 900
→ [tex]\frac{900}{5}[/tex] = 180
→ [tex]\frac{900}{10}[/tex] = 90
→ [tex]\frac{900}{15}[/tex] = 60
900 is the correct answer.
d) 225
→ [tex]\frac{225}{5}[/tex] = 45
→ [tex]\frac{225}{10}[/tex] = 22.5
→ [tex]\frac{225}{15}[/tex] = 15
225 is not divisible by 15
900 is the correct answer.
if x is the exterior angle and 70 and 50 are its opposite interior angle of a triangle find x please help me
Answer:
x = 120
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, then
x = 70 + 50 = 120
Answer:
X=120
Step-by-step explanation:
exterior angle of triangle is equal to its two opposite interior angles .
hence, X= 70 + 50
= 120
what is the circumference of a circle with an area of 20 pi
Answer:
28.1 units
Step-by-step explanation:
Area of circle= πr², where r is the radius.
Given that the area is 20π,
20π= πr²
Divide both sides by π:
20= r²
Square root both sides:
[tex]r = \sqrt{20} [/tex]
[tex]r = \sqrt{4(5)} [/tex]
[tex]r = ( \sqrt{4} )( \sqrt{5} )[/tex]
[tex]r = 2 \sqrt{5} [/tex]
Circumference of circle= 2πr
Substitute the value of r:
Circumference of the circle
[tex] = 2(\pi)( 2\sqrt{5} )[/tex]
[tex] = 4\pi \sqrt{5} [/tex]
= 28.1 units (3 s.f.)

Answer:
The measure of the angle ∠ABC is 108°
Step-by-step explanation:
An isosceles triangle has two equal sides and two equal angles
In this problem
∠BDA=∠BAD= 66° ----> the angles of the base are equals
Find the measure of the vertex angle
∠ABD = 180° - 2×66° = 48° (the sum of the internal angles of a triangle is equal to 180°)
then. Find the measure of the angle ∠CBD in the equilateral triangle we know that
The measure of the internal angle in a equilateral triangle is 60° so
∠CBD= 60°
Then find the measure of the angle ∠ABC
∠ABC=∠ABD+∠DBC
substitute the values
∠ABC= 48°+60° = 108°
The answer is 108°
The measure of the angle ∠ABC is 108°
Answer:
108 degrees
Step-by-step explanation:
Hi there!
1. Determine the measure of angle DBC
2. Determine the measure of angle ABD
3. Add them to determine the measure of angle ABC
We're given that triangle ABD is isosceles and triangle BCD is equilateral.
Because BCD is an equilateral triangle, all of its interior angles at 60 degrees.
Therefore, the measure of angle DBC is 60 degrees.
Triangle ABD is isosceles, so therefore, angle ADB is also 66 degrees.
The sum of the interior angles of a triangle is 180 degrees. Therefore, the measure of angle ABD is 180-66-66, which is 48 degrees.
To find ABC, add 60 and 48:
60+48 = 108
Therefore, angle ABC measures 108 degrees.
I hope this helps!
20% of a number is 17. Find the number.
Answer:
85
Step-by-step explanation:
20% x X = 17
20/100 x X = 17
X = 17 x 100/20
= 17 x 5
= 85
the number is 85
Answer:
17 is 20% of 85
Step-by-step explanation:
20%= 1/5 so 17 = 1/5 of that number if you multiple 17 by 5 that would equal 85.
17 is 20% of 85
David uses software to draw two triangles. He finds that he can use a rotation and a reflection to map one triangle onto the other, and he finds that the image of vertex D is vertex L, the image of vertex V is vertex C, and the image of vertex W is vertex Y. In how many different ways can David write a congruence statement for the triangles? Complete the explanation.
Use the given information to select congruence statements.
△DVW ≅ △
△DWV ≅ △
△VDW ≅ △
△VWD ≅ △
△WDV ≅ △
△WVD ≅ △
There are __ more ways with the order of the triangles reversed. There is a total of __ ways to write a congruence statement.
Transformation involves changing the position of a shape.
The complete statement is:
There are _3_ more ways with the order of the triangles reversed. There is a total of _9_ ways to write a congruence statement.
From the question, we understand that:
[tex]\mathbf{\triangle DVW \cong \triangle LCY}[/tex]
This mean that, the following 6 statements can be used as the congruent statements
[tex]\mathbf{\triangle DVW \cong \triangle LCY}[/tex]
[tex]\mathbf{\triangle DWV \cong \triangle LYC}[/tex]
[tex]\mathbf{\triangle VDW \cong \triangle CLY}[/tex]
[tex]\mathbf{\triangle VWD \cong \triangle CYL}[/tex]
[tex]\mathbf{\triangle WDV \cong \triangle YLC}[/tex]
[tex]\mathbf{\triangle WVD \cong \triangle YCL}[/tex]
A triangle has 3 sides, and there are 2 triangles in the question.
The number (n) of congruence statements is:
[tex]\mathbf{n = 3^2 = 9}[/tex]
The remaining (r) number of congruent statement is:
[tex]\mathbf{r = 9 - 6 = 3}[/tex]
So, the blanks should be completed with 3 and 9

What are the domain and range of the function f(x)=3 over 4 x+5
Answer:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values.
Step-by-step explanation:
Which answer choice shows how to find 352 ÷ 16 using partial quotients? Find the quotient and the value that goes in the box in Step 2. Step 1: Subtract (20 × 16) from 352 to get 32. Step 2: Subtract (☐ × 16) from 32 to get 0. Step 3: Add to find the quotient. A. □ = 1; 352 ÷ 16 = 21 B. □ = 1; 352 ÷ 16 = 32 C. □ = 2; 352 ÷ 16 = 22 D. □ = 2; 352 ÷ 16 = 52
Partial quotient is one of the ways of dividing expressions and numbers.
The value that goes into the box is 2.The quotient is 22.The quotient is given as:
[tex]\mathbf{352 \div 16}[/tex]
The first step is:
[tex]\mathbf{352 - (20 \times 16) = 32}[/tex]
The next step is:
[tex]\mathbf{32 - ([\ ] \times 16) = 0}[/tex]
Represent the blank with x
[tex]\mathbf{32 - (x \times 16) = 0}[/tex]
So, we have:
[tex]\mathbf{32 - 16x = 0}[/tex]
Collect like terms
[tex]\mathbf{16x = 32}[/tex]
Divide both sides by 2
[tex]\mathbf{x = 2}[/tex]
So, the value that goes into the box is 2.
The quotient is then calculated as:
[tex]\mathbf{Quotient = 20 + 2}[/tex]
[tex]\mathbf{Quotient = 22}[/tex]
Hence, the quotient is 22.
