Answer:
88/17
Step-by-step explanation:
5x · 7/8 - 3x · 3/4 = 11
35x/8 - 18x/8 = 17x/8
17x/8 = 11
17x = 88

Answer:
36 is the answer of this question
Answer:
Methods to Find LCM of 4, 9 and 12
Least Common Multiple of 4, 9 and 12 is the smallest number, which is exactly divisible by all of them without any remainder.
Multiples of 4 = 4, 8, 12, 16, 20, 24, 28, 32, 36.
Multiples of 9 = 9, 18, 27, 36.
Multiples of 12 = 12, 24, 36.
The graph shows the number of cycles of a crosswalk signal during the day and during the night.
Answer:
Step-by-step explanation:
a). Since, both the lines are passing through origin (0, 0) y-intercept of the lines are zero.
For day periods,
Let the equation is, y = mx
Since, this line passes through (2, 80),
80 = 2m
m = 40
Therefore, equation for the day periods will be,
y = 40x
For night periods,
Let the equation is, y = mx
Since, this lines passes through (3, 90),
90 = 3m
m = 30
Therefore, equation of the line is,
y = 30x
b). For x = 6 hours,
Number of cycles in the day (y) = 40 × 6 = 240
Number of cycles in the night (y) = 30 × 6 = 180
Therefore, difference in the cycles in day and night = 240 - 180 = 60
x + y = -6 The slope is and the y-intercept is

The diagram shows the position
of three towns represented by
letters A, B and C.
NA
B is 7 km from A on a bearing of 037°
C is 8 km from B on a bearing of 140°
Find the bearing of C from A.
Give your answer correct to 1 decimal place.
Answer:
Step-by-step explanation:
143º I’m not sure
The bearing of town C from town A is 93.3 degree if the B is 7 km from A on a bearing of 037° C is 8 km from B on a bearing of 140°
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
If we extend the line NA and NB
As we can see, line NA and NB are parallel and cut by transversal AB
The angle NBA and BAN' will be equal.
Angle BAN' = 180 - 37 = 143 degree = angle NBA
Angle CBA = 360 - 140 - 143
Angle CBA = 77 degree
Now, applying cos law:
b² = a² + c² - 2ac[cos B]
b² = (8)² + (7)² - 2(8 x 7 x cos77)
b = 9.37 km
To find the measure of the angle A applying sin law:
(sinA)/a = (sinB)/b
sinA = (axsinB)/b
sinA = (8xsin77)/9.37
A = 56.3⁰
Bearing of town C from town A:
α = A + 37⁰
α = 56.3⁰ + 37⁰
α = 93.3⁰
Thus, the bearing of town C from town A is 93.3 degree if the B is 7 km from A on a bearing of 037° C is 8 km from B on a bearing of 140°

A cylinder has a radius of 13 feet and a
height of 28 feet. Which statement about
the cylinder is not true?
a
The circumference is about 82 ft.
The area of one base is about 531 ft2
ОООО
The lateral area is about 2,286 ft?
The total surface area is about 2,818 ft?
Question 4 (1 nointi
Step-by-step explanation:
The radius of a cylinder, r = 13 feet
Height of the cylinder, h = 28 feet
The circumference of the cylinder is given by :
[tex]C=2\pi r\\\\=2\pi \times 13\\\\=81.68\ ft\\\\C=82\ ft[/tex]
The area of one base is given by :
[tex]A=\pi r^2\\\\=\pi \times 13^2\\\\=530.92\ ft^2\\\\=531\ ft^2[/tex]
The lateral area of the cylinder is given by :
[tex]A=2\pi r h\\\\A=2\pi\times 13\times 28\\\\A=2287.07\ ft^2[/tex]
Total surface of the cylinder is given by :
[tex]A=2\pi r h+2\pi r^2\\\\=2287.07+2\pi \times (13)^2\\\\=3348.92\ ft^2[/tex]
The total surface area of the cylinder is not matched with the given data. Hence, option (4) is not correct.
If , then what is mto the nearest degree?
Answer:
70 degrees
Step-by-step explanation:
If cosm<A = 342/1000, we are to find the value of a
Take arccos of both sides
cosm<A = 342/1000
cosm<A = .342
arccos(cosm<A) = arccos(0.342)
m<A = arccos(0.342)
m<A = 70 degrees
Hence the measure of m<A is 70 degrees
Are the two triangles similar? How do you know?
Answer:
Yes the triangles are similar.
if you look at Angle C it's 60° and F is also 60°
60 + 67 is 127
127 + 53 is 180° which is the amount a triangle is. (assuming that E is 67°)
Similar triangles may or may not be congruent triangles.
The two triangles are similar.
From the figure, we have:
[tex]\mathbf{\angle F \cong \angle C = 60}[/tex] ----- Angles F and C are corresponding
[tex]\mathbf{\angle D \cong \angle G = 53}[/tex] ----- Angles D and G are corresponding
[tex]\mathbf{\angle H \cong \angle E = 67}[/tex] ----- Angles H and E are corresponding
Add the above angles.
[tex]\mathbf{Sum = 60 + 53 + 67}[/tex]
[tex]\mathbf{Sum = 180}[/tex]
The sum of the angles equal 180 degrees,
Hence. the triangles are similar triangles.

uHhhhhHHHhHhHhHh heLp?
Answer and Step-by-step explanation:
Use the Pythagorean theorem to solve.
Plug in the value 5 for a, and 6 for b. c will stay as c.
[tex]a^{2}+ b^{2}= c^{2} \\\\\\5^{2}+6^{2}= c^{2} \\\\\\25 + 36= c^{2} \\\\\\61 = c^{2} \\\\\\\sqrt{61} = c[/tex]
5 squared is equal to 25, and 6 squared is equal to 36.We add those together to get 61.
We then square root both sides of the equation to get c by itself, resulting in the square root of 61.
The square root of 61 becomes 7.810249676
c = 7.8102
To check, you would multiply that number by itself, then you will get 61. With the rounded version, you would get close to 61.
If you got 7.08 as an answer, then multiplying it by itself results in 50.1264, which isn't close to 61.

5 donuts and 2 cups of hot Chocolate costs 24$. 2 donuts and 3 cups of hot chocolate costs 14$.How much does each donut and each cup of hot chocolate cost
Answer:cost of each donut =$4
and cost of each cup of hot chocolate =$2
Step-by-step explanation:
Step 1
Let donuts be represented as d
and cups of hot chocolate be rep as c so that
5 donuts and 2 cups of hot Chocolate costing 24$ will be expressed as
5 d+ 2 c= 24
And 2 donuts and 3 cups of hot chocolate costing 14$ will be expressed as
2d +3 c= 14
Step 2
Using elimination method,Multiply equation 1 by 3 and equation 2 by 2
15d+ 6c= 72----equation 3
4d+ 6c= 28-----equation 4
Subtracting equation 4 from equation 3 gives us
11 d=44
d= 44/11
d= 4
To find c, using equation 1
5 d+ 2 c= 24
5 x 4+ 2c=24
20+2c=24
2c=24-20
2c=4
c=4/2 =2
cost of each donut =$4
and cost of each cup of hot chocolate =$2

A runner runs at an average speed of 9 m/s for 20 seconds
How far did the runner run in metres?
Answer:
The answer would be 180 meters.
Step-by-step explanation:
We are told the runner runs at 9 m/s for 20 seconds.
Since they run 9 meters per second, all we have to do is multiply 9 by 20, which will give us 180 meters.
9 x 20 = 180

The circumference of a circle is 9.31cm. Find the length of the diameter. Give your answer rounded to 2 DP.
Answer:
2.96cm
Step-by-step explanation:
C= 2x Pi x Radius
9.31 = 2 x Pi x Radius
9.31/2 = Pi x Radius
4.655 = Pi x Radius
4.655/3.14 = Radius
1.4824840764331210191082802547771 = Radius
Now, that you have worked out the radius which is half the diameter
Radius + Radius = Diameter
1.4824840764331210191082802547771 + 1.4824840764331210191082802547771 = 2.964968153
= 2.96cm to 2 d.p
You can double check because C= 2 x Pi x Radius
9.31 = 2 x 3.14 x 1.482
