Answer:
80%
Step-by-step explanation:
4/5 as a percentage would be 8/10ths, or 80%
By multiplying the fraction to get a denominator of 10, you get 8 over 10. Therefore it would be 80 percent of 100.

Answer: 12
Step-by-step explanation:
A straight line has a measurement of 180° so these two angles added together will equal 180°.
(10x - 20)° + (6x + 8)° = 180°
10x° + 6x° + 8° - 20° = 180°
16x° -12° = 180°
16x° = 192°
x = 12
Supplementary angles
10x-20+6x+8=18016x-12=18016x=180+1216x=192x=192/16x=12Write the standard equation for the circle center (6, 7), r = 9.
Answer:
[tex](x-6)^{2} +(y-7)^{2} =81[/tex]
Step-by-step explanation:
The general equation for a circle is
[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex] where (h,k) is the center of the circle and r is the radius
Plug in the (6,7) for the center and 9 for r

If each vowel in the word COLLEGE substitutes with the next letter of the English alphabetical series and each constant is substituted with the 2nd letter preceding it. How many vowels are present in the new arrangement? Fast plsssssssssssss with steps....
Answer:
2
Step-by-step explanation:
Following the substitution rules:
O becomes P and
E becomes F
because they are vowels(a,e,i,o,u) change to next letter.
C becomes A
L becomes J
G becomes E
because constants change to the letter two before the given letter.
So COLLEGE becomes APJJFEF
so it now has 2 vowels.

Equation:
Solution: x=
Jadyn is( ) years old.
Answer:
12 years old
Step-by-step explanation:
3x+5=41
3 times a number and 5 more
'more' usually means adding
41-5 =36
36/3 =12
Answer:
Equation: 41 = 3x + 5
x = 12
Step-by-step explanation:
Hello!
Betty is 5 more than 3 times Jadyn's age. Since Jadyn's age is unknown, we'll call that unknown variable x.
Betty is 5 more than 3 times x. Betty is also 41 years old.
Equation: 41 = 3x + 5
Now we have to solve for x
Solve for x:
41 = 3x + 536 = 3xx = 12
Jadyn is 12 years old.

Devaughn is 6 years older than Sydney. The sum of their ages is 80. What is Sydney's age?
Answer:
37 and 43
Step-by-step explanation:
There are some ways to do this, but this is what I like to do. First, since there are 2 people, I divide 80 by 2, which is 40. Now I add 3 to one person and subtract 3 from one person, because the age difference is 6 years, and there are two people (if you divide them you get 3). Now you get the answer; 37 and 43.
The figure formed by (−3, 2), (−4, 1), and (−1, −5) is translated 3 units right and 5 units up. What are the coordinates of the new figure?
Translating the figure involves chaging the position of the figure
The coordinates of the new figure are (0, 7), (1 , 6), and (2, 0)
The coordinates of the new figureThe coordinates are given as:
(−3, 2), (−4, 1), and (−1, −5)
The rule of translation 3 units right and 5 units up is:
(x + 3, y + 5)
So, we have:
(−3 + 3, 2 + 5), (−4 + 5 , 1 + 5), and (−1 + 3, −5 + 5)
Evaluate the sum
(0, 7), (1 , 6), and (2, 0)
Hence, the coordinates of the new figure are (0, 7), (1 , 6), and (2, 0)

What is the length of BD?
A. 53.3 units
B. 30 units
C. 67.5 units
D. There is not enough information to determine the length of BD.
Answer: B
Step-by-step explanation:
The dimensions of a rectangular garden were 5 m by 12 m. Each dimension was increased by the same amount. The garden then had an area of 120 m2. Find the dimensions of the new garden.
if dimensions were 5 and 12, that means ratio was 5:12. if we increase wach dimension by the same amount, the ratio is the same.
so:
5x×12x=120
60x²=120
x²=120÷60
x²=2
x=√2
that means each dimension was increased by √2
so dimensions are: 5√2 and 12√2

A small bus has seats for 16 passengers. Which equation can be used to find the number of passenger seats, n, in b small
buses?
A
n = 16-b
B
b = 16n
C
b = 16+n
D
n = 16b
Answer:
D, n=16b
Step-by-step explanation:
There are 16 busses, each of which can hold 16 seats. There are n of those busses.
Therefore, 16*n = the total number of seats on the busses altogether.
Kevin is remodeling his bathroom. He needs to cut a circular hole out of a countertop to place the sink, as shown in the figure. What will be the area of the countertop once Kevin cuts the hole, to the nearest square inch? Use 3.14 as an approximation for pi.
Answer:
838 inches²
Step-by-step explanation:
Finding the area of the countertop including the hole
⇒ Area of countertop including hole: LB
⇒ Area of countertop including hole: (24)(48)
⇒ Area of countertop including hole: 1152 inches²
Finding the area of the hole (sink)
⇒ Area of hole: πr²
⇒ Area of hole: (π)(D/2)²
⇒ Area of hole: (π)(20/2)²
⇒ Area of hole: (π)(10)²
⇒ Area of hole: (π) x 100
⇒ Area of hole: 3.14 x 100 = 314 inches²
Finding the area excluding the hole
1152 - 314 = Area of countertop (excluding the hole)
838 inches² = Area of countertop (excluding the hole)
Find the slope of the line that is parallel and perpendicular to the following equation.
2x - y = 1
Answer:
Slope of the line that is parallel: 2
Slope of the line that is perpendicular: [tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
For the parallel line:
Rewrite your equation to slope-intercept form: y = mx + b
y = mx + b
m = slopeb = y-intercept (when x = 0)2x - y = 1 <== subtract 2x to both sides
-2x -2x
-y = -2x + 1 <== divide both sides by -1
/-1 /-1
y = 2x - 1
The slope of the line that is parallel to this line is 2.
For the perpendicular line:
*Perpendicular lines have negative reciprocals*
Steps:
1. Take your original slope (2)
2. Flip it (1/2)
3. Change the sign (-1/2)
For a slope of 2, the reciprocal would be: [tex]-\frac{1}{2}[/tex]
Hope this helps!
Note that.
Slopes of parallel line are equal
Slopes of perpendicular lines are negative reciprocals
So
2x-y=1y=2x-1Compare to slope intercept form
slope=m=2Slope of the parallel line=2
Slope of the perpendicular line=-1/2

Hey ! Buddy
Question : -Find the value of x .
Given : -Angle 1 = x°Angle 2 = 43°Angle 3 = 36°To Find : -We have to find the value of x .
Concept : -The concept of this question belongs to the sum of all the three interior angles of triangle i.e. sum of all the three interior angles of triangle is equal to 180° .
So Our Solution Starts From Here :As we know that sum of all the three interior angles of triangle is equal to 180° . So ,
[tex] \rightarrow \: Angle \: 1 + Angle \: 2 \: + Angle \: 3= 180°[/tex]
Now , substituting values of Angle 1 , 2 and 3 :
[tex] \longmapsto \: x° + 43° + 36° = 180° [/tex]
Now , adding 43 and 36 in right hand side :
[tex] \longmapsto \: x° + 79° = 180° [/tex]
Now , transposing 79° to right hand side :
[tex] \longmapsto \: x° = 180° - 79° [/tex]
Now , subtracting 79° from 180° :
[tex] \longmapsto \: \pink{\boxed{ { \bold{x° = 101°}}}}[/tex]
Therefore , value of angle x is 101°.#[tex] \sf{Keep \: Learning}[/tex]what is the formula of equilateral triangle .class-8
Answer:
Step-by-step explanation:
The perimeter of an equilateral triangle is:
P = 3a (where a any length of the triangle)
The area of an equilateral triangle is:
[tex]A = \frac{\sqrt{3} }{4} a^{2}[/tex] (where a is the side length)
Using the area formula we can rearrange it to get the formula of the length of the equilateral triangle:
[tex]a = \frac{2}{3} 3^{\frac{3}{4} } \sqrt{A}[/tex]
Then three important formulas are
[tex]\\ \rm\Rrightarrow Perimeter=3s[/tex](As sides are equal)
[tex]\\ \rm\Rrightarrow Area=\dfrac{\sqrt{3}}{4}s^2[/tex]
[tex]\\ \rm\Rrightarrow Height=\dfrac{\sqrt{3}s}{2}[/tex]

A graph shows the preimage and image of a shape that has undergone one transformation. If the preimage and image are not congruent what transformation was applied?
A. reflection
B. rotation
C. dilation
D. translation
Answer:
C. dialtion
Step-by-step explanation:
A dialtion either reduces or enlarges the dimensions of a shape, causing for them to no longer be congruent.
A reflection wouldn't change the congruency of the shape since it is just reflecting it across whatever axis. The dimensions stay the same.
A rotation would simply rotate/turn the shape. The dimensions would not be changed.
A translation would slide the shape elsewhere whether it be vertically, horizontally, or diagonally. The dimensions would not change.
Therefore, we can conclude that option C makes the most sense.
