Answer:
£22 : £44 : £66 : £110
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 + 3 + 5 = 11 parts
Divide the amount by 11 to find the value of 1 part of the ratio
£242 ÷ 11 = £22 ← value of 1 part of the ratio, then
2 parts = 2 × £22 = £44
3 parts = 3 × £22 = £66
5 parts = 5 × £22 = £110
Then £242 in the ratio 1 : 2 : 3 : 5 is £22 : £44 : £66 : £110
Jim works in real estate sales. His annual salary is $20,000 plus 2.5% of his home sales. What was the total value of all homes he sold if his annual pay for the year was $120,000?
Answer:
$40,000
Step-by-step explanation:
2.5x+20,000=120,000
120,000-20,000=100,000
100,000/2.5=40,000
Please help me with this x+125+d=1,245
Answer:
x=1120-d
Step-by-step explanation:
Answer:
x = 1120 - d
Step-by-step explanation:
Hi there!
We can simplify this using orders of operations.
First, subtract 125 from both sides to get x + d = 1120.
To isolate x, just subtract d from both sides.
If you give me a value for d, i can solve the full problem.
I hope this helps!

Let's compare 7/9 and 5/6. First, write the fractions with the same denominator. 7/9 = 5/6= Then, use <, =, or > to compare the fractions. 7/9 5/6
Answer:
7/9 < 5/6
Step-by-step explanation:
The denominator is the common factor of the denominators
That is 54
So we have
7/9 * 6/6 = 42/54
5/6 * 9/9 = 45/54
So, the relation we have is that;
7/9 < 5/6

In 2000, the world population was 6.1 billion. In 2015, the world population was 7.3 billion. Work out the percentage increase in population. Give your answer correct to 1 decimal place.
Answer:
19.7%
Step-by-step explanation:
Given that,
In 2000, the world population was 6.1 billion.
In 2015, the world population was 7.3 billion.
We need to find the percentage increase in population. The percent increase in this case is given by :
[tex]\%=\dfrac{7.3-6.1}{6.1}\times 100\\\\=19.67\%\\\\=19.7\%[/tex]
So, the increase in population is 19.7%.

1kg petrol has density of 800kg/m3 find its volume in cm 3
Answer:
1.25*10-3m^3
Step-by-step explanation:
1kg petrol has density of 800kg/m3 find its volume in cm 3
Given data
mass m= 1kg
density = 800kg/m3
Required
The volume v
We know that
density= mass/volume
so
Volume= mass/density
substute
Volume= 1/800
volume=1.25*10-3m^3
Hence the volume is 1.25*10-3m^3
(1,9) m=-3 in point slope form

Find the increasing functions. Then arrange the increasing functions in order from least to greatest rate of change. (not all of the functions will be used)
y= 5/2x + 10
y= -1/2x + 1/2
y= 3/2x - 11/2
y= 1/2x - 2
y= 4/3x - 7/3
y=3/4x - 10
Answer:
to a function is increasing we have to find the slope of the function
the higher the slope the faster the growth
Step-by-step explanation:
slope = 5/2. which is 2.5slope 2 = -1/2 which is -0.5slope 3 = 3/2 which is 1.5slope 4 = 1/2 which is 0.5slope 5= 4/3 which is 1.33slope 6 = 3/4 which is 0.75so the function in increasing order
y= -1/2x + 1/2
y= 1/2x - 2
y=3/4x - 10
y=4/3x -7/3
y=3/2x-11/2
y=5/2x +10

In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°. Find all possible values of ∠V, to the nearest 10th of a degree.
Answer:
The possible values for ∠V is 81.2° and 98.8°
Step-by-step explanation:
In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°. Find all possible values of ∠V, to the nearest 10th of a degree.
We solve the above question using Sine rule
Sine rule
= u/sin U = v/sin V
In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°
Hence:
7.6/sin 68° = 8.1/sin V
Cross Multiply
7.6 × sin V = sin 68° × 8.1
sin V = sin 68° × 8.1/7.6
V = arc sin ( sin 68° × 8.1/7.6)
V = arc sin (0.99)
V = 81.18°
Another value for V = 180° - 81.18°
= 98.82°
Therefore, the possible values for ∠V approximately to the nearest tenth of a degree is 81.2° and 98.8°

Last week the price of apples at fifer farm was $1.50 per pound this week the price has decreased by 20% what is the price of apples this week
Answer:
1.20 per pound
Step-by-step explanation:
calculating what the percent is taken from 1.50, simply take the period out of the 150 and multiply by x .20 to get 30 from it, then subtract 30 from 150 to get 120 and from there you can add the period back in. Hope this helps !

Answer:
∠CAD = 44⁰
∠ACD = 44⁰
∠ACB = 136⁰
∠ABC = 22⁰
Step-by-step explanation:
To calculate m∠CAD;
Line AD = Line DC,
thus ∠CAD = ∠ACD = ¹/₂(180 - 92°) [sum of angles in a triangle.]
∠CAD = ¹/₂ x 88 = 44⁰
Also, ∠ACD = 44⁰
To calculate m∠ACB;
∠ACB = 180 - ∠ACD [Sum of angles on a straight line]
∠ACB = 180 - 44
∠ACB = 136⁰
To calculate m∠ABC;
Line CB = Line CA
Thus, ∠ABC = ∠CAB = ¹/₂(180 - ∠ACB) [sum of angles in a triangle.]
∠ABC = ¹/₂(180 - 136)
∠ABC = ¹/₂ x 44
∠ABC = 22⁰
