Answer:
x = 15
Step-by-step explanation:
Angles in a triangle add up to equal 180
Hence, 3x + 5x + 4x = 180
( Note that we've just created an equation that we can use to solve for x)
We now solve for x using the equation created
3x + 5x + 4x = 180
Combine like terms
12x = 180
Divide both sides by 12
x = 15
Answer:
x = 15
Step-by-step explanation:
The sum of the angles of a triangle is 180
3x+4x+5x = 180
Combine like terms
12x = 180
Divide by 12
12x/12 =180/12
x = 15
what is the answer to -3x-5y=4?
What is the value of X in the figure below? In this diagram ∆ABD is similar to ∆CAD.
Answer:
F. 45/4Step-by-step explanation:
Corresponding sides have same ratio:
AB/AC = BD/ADFind AB:
AB = [tex]\sqrt{20^2-15^2} = 5\sqrt{7}[/tex]Find AD:
AD = √15²-x²Now the ratio:
5√7/15 = (20 - x)/√(15²-x²)√7 *√(225-x²)= 3(20 - x)7(225 - x²) = 9(20 -x)²7*225 - 7x² = 9(400 - 40x + x²)1575 - 7x² = 3600 - 360x + 9x²16x² - 360x + 2025 = 0(4x)² - 2*4x*45 + 45² = 0(4x - 45)² = 04x - 45 = 04x = 45x = 45/4Correct choice is F
Four months ago, Cynthia signed up to receive email notifications to remind her to change her contact lenses,
Cynthia's first email arrived 9 days after she set up the notifications, and her second email arrived 14 days after
the first. Emails continued to arrive every 14 days.
Assuming n is a positive integer, which function gives the number of days, c(n), after Cynthia set up the
notifications that her nth email arrived?
Answer:
I think 14n + 9
Step-by-step explanation:
since she got her first email in 9 days and got her second email 14 days later, and it continues to appear every 14 days.
so I think it must be 14n + 9
please help me answer this!!
Answer:
(x, y) = (10, 290)
Step-by-step explanation:
From the table
Total fees = fixed + variable
Fixed:
When number of times Ahmed mowed, x = 0
y = 40
When x = 2, y = 65
Rate of change = y2 - y1
= 65 - 40
= 25
y = 40 + 25x
Where,
y = total fees charged
40 = fixed fee
25x = variable fee
Total amount Ahmed will make for mowing 10 times
when x = 10
y = 40 + 25x
y = 40 + 25(10)
= 40 + 250
= 290
y = 290
(x, y) = (10, 290)

a)-3/5
b)-4/3
c)-4/5
d)-3/4
m
(2y+19)
(5x+20)
n
(4x-11)
Answer:
(5x+20)+(4x-11)=180(linear pair)
9x+9=180
9x=180-9
9x=171
x=171/9
x=19
now,
(2y+19)+(5x+20)=180(co-interior angle)
2y+19+5×19+20=180
2y+134=180
2y=180
y=180/2

a bicycle travels at a velocity of -2.33m/s and has a displacement of -58.3m how much time did it take??
Answer:
25.02 s
Step-by-step explanation:
velocity = distance/time
rearrange for time:
time = distance/velocity
time = -58.3m/-2.33 m/s
time = 25.02s

Find the area of the shaded region.
Answer:
[tex]48\pi\\\approx 150.796[/tex]
Step-by-step explanation:
1.Approach
To solve this problem, find the area of the larger circle, and the area of the smaller circle. Then subtract the area of the smaller circle from the larger circle to find the area of the shaded region.
2.Find the area of the larger circle
The formula to find the area of a circle is the following,
[tex]A=(\pi)(r^2)[/tex]
Where (r) is the radius, the distance from the center of the circle to the circumference, the outer edge of the circle. ([tex]\pi[/tex]) represents the numerical constant (3.1415...). One is given that the radius of (8), substitute this into the formula and solve for the area,
[tex]A_l=(\pi)(r^2)\\A_l=(\pi)(8^2)\\A_l=(\pi)(64)[/tex]
3.Find the area of the smaller circle
To find the area of the smaller circle, one must use a very similar technique. One is given the diameter, the distance from one end to the opposite end of a circle. Divide this by two to find the radius of the circle.
8 ÷2 = 4
Radius = 4
Substitute into the formula,
[tex]A_s=(\pi)(r^2)\\A_s=(\pi)(4^2)\\A_s=(\pi)(16)[/tex]
4.Find the area of the shaded region
Subtract the area of the smaller circle from the area of the larger circle.
[tex]A_l-A_s\\=64\pi - 16\pi\\=48\pi[/tex]
[tex]\approx150.796[/tex]

Answer:
Hello there, lol.
Adjacent = Opposite/ Tan(35)
Adjacent = 4.3
Answer:
4.28
Step-by-step explanation:
basically using the sine ratios :
a/sinA = b/sinB = c/sinC
so, let's call the known side a (3) and its opposing angle A (35 degrees).
and we know C is 90 degrees.
sin(90) = 1
b = the missing side AC.
and because the sum of all angles in a triangle is always 180 degrees, the missing angle B is
B = 180 - 90 - 35 = 55
AC/sin(55) = 3/sin(35)
AC = b = sin(55) × 3/sin(35) = 4.28
a little more practice and calculate also c that way :
3/sin(35) = c/1
c = 3/sin(35) = 5.23
(x+y,x-2y)=(4,1), find x and y
Answer:
x =3 and y =1
Step-by-step explanation:
( x+y , x-2y) = (4 , 1)
compare their corresponding elements
x+y = 4
y = 4 - x equation (i)
x-2y =1
substitute the value of x
x - 2(4 - x) =1
x - 8 + 2x =1
3x = 1 +8
x = 9/3
x = 3
Now substitute the value of x in equation (i)
y = 4 - x
y = 4 - 3
y = 1
Answer:
x = 3, y = 1
Step-by-step explanation:
Equate the x and y coordinates of the given points
x + y = 4 → (1)
x - 2y = 1 → (2)
Subtract (2) from (1) term by term to eliminate x
0 + y - (- 2y) = 4 - 1
y + 2y = 3
3y = 3 ( divide both sides by 3 )
y = 1
Substitute y = 1 into (1) for corresponding value of x
x + 1 = 4 ( subtract 1 from both sides )
x = 3
Florence invests £200 for two years at 5% compound interest paid yearly. Liam says that the interest that Florence will receive will be £20 is Liam right?
Answer:
No, Liam is wrong
Step-by-step explanation:
Amount invested by Florence = £200
Formula for compound interest = P * (1 + R / 100)^Time period
P = £200
R = 5%
Time period = 2
£200 * (1 + 5/100) ^ 2
=> £200 * 1.05^2
=>£200 * 1.1025
=> £220.5
So the interest = 220.5 - 220 = 20.5
20.5 ≠ 20
Therefore, Liam is wrong.
Hope it helps :)

Answer:
12.56 in ^2
Step-by-step explanation:
First find the area of a circle with radius 4
A = pi r^2
A = (3.14) 4^2
A =50.24
Since it is 1/4 of a circle, multiply by 1/4
1/4 ( 50.24)
12.56
Answer:
Quarter circle's area is 12.56 inches².
Step-by-step explanation:
Concept:- Firstly, we need to find the area of circle and Since, it is quarter of circle we need to multiply the area of circle by 1/4. and we get answer
✯ Solution ✯Finding area of circle
Using Formula
Area of circle = π × r ²
Where,
r ,is the radius of circleAnd we have given
Radius, r of circle is 4 in.Value of π is 3.14Substitute the value into the formula
Area of circle = 3.14 × ( 4 in. )/²
now,
Area of circle = 3.14 × 16 in ².
multiply , we get
Area of circle is 50.24 nches ²
As have to find the quarter circle's area ,
and we know that quarter is the one fourth of the circle .
Quarter circle's area = Area of circle × 1/4
Multiply , we get
Quarter circle's area = 50.24 × 1/4
Therefore, quarter circle's area is 12.56 inches².
Work out the sizes of the ANGLES
Answer:
r = 55°, s = 25°, t = 30°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Sum the 4 angles in the top quadrilateral and equate to 360
r + 100° + 110° + 95° = 360°
r + 305° = 360° ( subtract 305° from both sides )
r = 55°
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180° in the left triangle for s
s = 180° - (100 + 55)° = 180° - 155° = 25°
Similarly for the triangle on the right for t
t = 180° - 95 + 55)° = 180° - 150° = 30°
Answer:
Step-by-step explanation:
In quadrilateral ADEF
r + 95 +100 +110 = 360 {Sum of all angle of quadrilateral}
r + 305 = 360
r = 360 -305
r = 55
In triangle AEC,
r + 95 + t = 180
55 + 95 + t = 180
150 + t = 180
t = 180 -150
t = 30
In triangle ABD,
r +s + 100 = 180
55 + s + 100 = 180
s + 155 = 180
s = 180 - 155
s = 25
