7. Find: (i) x + y +z (ii) a+b+c+d
Answer:
Q.1 360° Q.2 360°
Step-by-step explanation:
Q.1 let the third angle of the triangle be a
70°+40°+a=180(by angle sum property)
110°+a=180
a=180°-110°
a=70°
angle x=70°+x=180°(linear angle)
x=180°-70°
x=110°
angle z= 40°+z=180
z= 180°-40°
z=140°
angle y=a+y=180°
70°+y=+80°
y=180°-70°
y=110°
y+z+x=110° +110° +140°=360
Q.2 let the fourth angle of the quadrilateral be x
120°+70°+60°+ x=360° (by angle sum property)
250°+x=360°
x=360°-250°
x=110°
angle a=120°+a=180°(by linear angle)
a=180°-120°
a=60°
angle b=70°+b=180°
b=180°-70°
b=110°
angle c=x+c=180°
110° + c=180°
c=180°-110°
c=70°
angle d=60°+d=180°
d= 180° -60°
d=120°
a+b+ c+d=120°+110°+60°+70°=360°
What is the solution set for the inequality below
-3x + 15 < 18
Answer:
x > -1
Step-by-step explanation:
-3x + 15 < 18
Subtract 15 from each side
-3x + 15-15 < 18-15
-3x < 3
Divide each side by -3, remembering to flip the inequality
-3x/-3 > 3/-3
x > -1

20% of all the children in a class are left handed.
4 children are left handed.
How many children are there in the class altogether?
Answer:
There are 20 students in the class
Step-by-step explanation:
Let the total number of children in the class be = x
from the question, we know that 20% of all the children are left-handed. We also know that 20% of the total children in the class = 4.
This means that 20% of x = 4
Wherever we see the word "of" in an arithmetic problem, we should know that it infers a multiplication there.
Hence, we have
[tex]\frac{20}{100} \times x = 4[/tex]
[tex]x = \frac{4 \times 100}{20}= 20[/tex]
There are 20 children in the class altogether

a bus travels 320 miles in 6.4 hours. if the bus continues at the same rate, which proportion can be used to find m, the number of miles the bus will travel in 9 hours.
Answer:
A
Step-by-step explanation:
Ok first we need to find rate of MILES per HOUR
320/6.4=50
m= miles in 9 hours
9*50=450
Cross Multiplyis your answer
A
(6.4*9)/320m=Hours/miles
Hope this helps!
The number of miles the bus will travel in 9 hours will be 6.4 / 320 = 9 / m. Then the correct option is B.

Step-by-step explanation:
Colin buys a tv for £780.
It depreciates at a rate of 5% per year.
How much will it be worth in 6 years?
Give your answer to the nearest penny where appropriate.
Answer:
£573.40
Step-by-step explanation:
Amount = cost price - total depreciation
depreciation (1st year ) = 5% of £780
= [tex]\frac{5}{100}[/tex] x 780
= 0.05 x 780
= £39.00
depreciation (2nd year) = 5% of £741
= £37.05
depreciation (3rd year) = 5% of 703.95
= £35.1975
depreciation (4th year) = 5% of 668.7525
= £33.437625
depreciation (5th year) = 5% of 635.314875
= £31.76574375
depreciation (6th year) = 5% of 603.5491313
= £30.17745656
Total depreciation = £39.00 + £37.05 + £35.1975 + £33.437625 + £31.76574375 + £30.17745656
= £206.6283253
Total depreciation = £206.6283253
Therefore,
Amount after 6 years = £780 - £206.6283253
= £573.3716747
= £573.40
The worth of the TV after 6 years is £573.40.
