Answer:
Answer:x =6
Answer:x =6Step-by-step explanation:
Angle in a triangle is 180
75+ (7x+14) +49 =180
75+ 49+ (7x+14)= 180
124+ (7x+ 14) = 180
124+ 14 +7x= 180
138+7x = 180
7x =180- 138
7x=42
x= 6
2. Writing a set in Roster Method means you list the elements of sets inside the braces separated by commas; while writing the set using Set Builder Notation means writing the wet in words or description inside the braces. Examples are shown below: Given: Set A is a set of vowels The elements are a, e, i, o, u Roster Method A= {a, e, i, o, u Set Builder Notation A = {x / x is a vowels So, write the following sets in Roster Method and Set Builder Notation. a. Bis a set of days in the week that starts with letter S Roster Method Set Builder Notation: b. Cis a set of letters in the word PHILIPPINES Roster Method
The sets can either be presented in set builder form or roaster form. The
given sets presented in the required form are;
a. The set B is the set of days in the week that starts with letter S
Therefore;
The elements of B are; Saturday, Sunday
In roster method, we have; B = {Saturday, Sunday}
In set builder notation, we have; B = {x | x is a days in the week that starts with letter S}
b. C is the set of letters in PHILIPPINES
In roster form, we have; C = {P, H, I, L, I, P, P, I, N, E, S}
In set builder notation, we have; C = {Letters in the word PHILLIPINES}

Answer:
- The graph is decreasing over its entire domain
- The graph is symmetrical about the origin
Step-by-step explanation:
The graph has an unremovable discontinuity at X=0, therefore all continuity answers are incorrect.
The graph is neither symmetrical about the x-axis nor y-axis, but if it were to be rotated around the origin, it would be symmetric.
On both sides of the graph, the slope is decreasing.
Therefore:
- The graph is decreasing over its entire domain
- The graph is symmetrical about the origin
If the directrix is y = 4 and the focus is at
(3,0), the value of p is:
Using the equation of an parabola, it is found that the value of p is 0.5.
The equation of a parabola that is concave to the left or to the right, that is, that has directrix y = k, and vertex (h,k), is given by:
[tex](y - k)^2 = 4p(x - h)[/tex]
The focus is at: (h, k + p).
The directrix is at: y = k - p
For this problem, we have that:
Focus at (0,3), thus [tex]k + p = 3 \rightarrow k = 3 - p[/tex].Directrix at y = 4, thus [tex]k - p = 4[/tex]Since [tex]k = 3 - p[/tex]:
[tex]3 - p - p = 4[/tex]
[tex]2p = 1[/tex]
[tex]p = \frac{1}{2}[/tex]
[tex]p = 0.5[/tex]
The value of p is 0.5.

What is the area of shape b
Answer:
312.5 cm²
Step-by-step explanation:
Since the figures are similar , then
ratio of heights = a : b
ratio of areas = a² : b²
Here linear ratio = 12 : 15 = 4 : 5 , then
ratio of areas = 4² : 5² = 16 : 25
let x be the area of B , the using proportion
[tex]\frac{200}{16}[/tex] = [tex]\frac{x}{25}[/tex] ( cross- multiply )
16x = 5000 ( divide both sides by 16 )
x = 312.5
Area of shape B is 312.5 cm²

What is the ratio of the area of a circle with an 8 m diameter to a
circle with an 8 m radius?
Answer:
8d : 8r = Ratio = 1 : 4
Step-by-step explanation:
Area of 8cm diameter = 4cm radius = formula pi x 4^2
= 50.2654825
= 50.27 m^2 rounded to 2dp as meters
Area of 8cm radius = formula pi x 8^2
=201.06193
= 201.06,^2 rounded to 2dp as meters
201.06193 / 50.2654825 = 4
4 x 50.265 = 201.061
= 1 : 4
8d : 8r = Ratio = 1 : 4
The ratio of the area of circle with an 8m diameter to a circle with an 8m radius is 1:4.
What is ratio?A term that is used to compare two or more numbers and to indicate how big or small a quantity is when compared to another is called ratio.
What is area of circle?Area of a circle is the region covered or enclosed within its boundary.
What is the formula for the area of circle?The formula for the area of circle is give by
[tex]Area = \pi r^{2}[/tex]
Where,
r is the radius of the circle
According to the given question.
We have two circle.
One with the diameter 8m.
⇒ Radius, [tex]r_{1} = \frac{8}{2} =4m[/tex]
Therefore,
the area of circle with 4m radius
= [tex](4)^{2} \pi[/tex]
[tex]=16\pi[/tex]
Also, another circle with the radius 8m.
Therefore,
The area of the circle with the radius 8m
[tex]\pi (8)^{2} \\= 64\pi[/tex]
So,
the ratio of the area of circle with an 8m diameter to a circle with an 8m radius = [tex]\frac{16\pi }{64\pi } =\frac{1}{4}[/tex]
Hence, the ratio of the area of circle with an 8m diameter to a circle with an 8m radius is 1:4.

Answer:
13.896 kg
Step-by-step explanation:
Volume of Gold Bar = Area of [Trapezium x Length of Bar]
Length of Bar = 16 cm
Area of Trapezium = 2 × Area of Triangle + Area of Rectangle
Area of Triangle = 0.5 × 5 × 3 = 7.5 cm²
2 × Area of Triangle = 2 × 7.5 = 15 cm²
Area of Rectangle = 6 × 5 = 30 cm²
Area of Trapezium = 15 + 30 = 45 cm²
Volume of Gold Bar = 45 × 16 = 720 cm³
Density of Gold = 19.3 g/cm³
Mass of Gold Bar = 720 × 19.3 = 13896 g = 13.896 kg
Mass of Gold Bar = 13.896 kg
Therefore the mass of the Gold Bar is: 13.896 kg (kilograms).
Answer:
13.896kg
Step-by-step explanation:
First, find the volume of the trapezium.
Volume = area of cross-sectional area times the length (16cm)
[(a+b)/2] times height
(6+12)/2 x 5
(18/2) x 5
9 x 5
= 45 <-- area of cross section
45 x 16 = 720 cm^3 <-- volume
To find the mass, multiply volume times density
720 x 19.3 = 13 896g = 13.896kg

Answer:
[tex]\dfrac{2}{8}=25\%[/tex]
Answer: 2/8 (1/4 simplified.) 0.25(decimal form)
Step-by-step explanation:
If 6/8 are dog bones, then we subtract 8/8-6/8. We get 2/8. If the fraction needs to be simplified, then we get 1/4. If a decimal is needed, then we divide 2 by 8. We get 0.25.

- 0.2 ( 25x + 5 ) - 5 = 4
Answer:
x= -2
Step-by-step explanation:
-0.2(25x+5)-5 = 4
We move all terms to the left:
-0.2(25x+5)-5-(4) = 0
We add all the numbers together, and all the variables
-0.2(25x+5)-9 = 0
We multiply parentheses
-5x-1-9 = 0
We add all the numbers together, and all the variables
-5x-10 = 0
We move all terms containing x to the left, all other terms to the right
-5x= 10
x= 10/-5
x= -2
Answer:
x=-2
Step-by-step explanation:
step 1 -5x-1-5=4
step 2 -5x-6=4
step 3 -5x=10 cause you add 6 on both sides
step 4 and then divide both sides by -5 to get x=-2
