The ratio of the number of Baskin Robbins :Cold stone ice cream cones sold in a day is 11:9.If the number of Baskin Robbins cone sold is 44 .(a)How many cold stone cones are sold ? (b)If the number of cold stone cones on the next day is reduced to 20.what is the new ratio?
answer fast plsssssssssssssssssssssssssssssssss
Answers
Answer:
a) 36
b) 11:5
Step-by-step explanation;
a) let the number of cold stone cones be x
Since the initial ratio is 11:9
we have the ratio of the ice creams as;
11:9 = 44:x
11/9 = 44/x
11 * x = 9 * 44
x = (9 * 44)/11
x = 9 * 4 = 36
b) Now, from 36, we have a number of cold stones as 20
So the ratio now will be;
44:20
and that would be;
11:5

Answers
Answer: £122.4
Step-by-step explanation:
Given
The rate of interest is 4%
The principal invested is £1500
the time period is 2 years
Compound interest is given by
[tex]C.I.=P(1+r\%)^t-P[/tex]
put values
[tex]C.I.=1500(1+0.04)^2-1500\\C.I.=1500[1.04^2-1]\\C.I.=1500[1.0816-1]\\C.I.=1500\times 0.0816\\C.I.=122.4[/tex]
Therefore, interest earned is £122.4

The circumference of a circle is 8.44cm.
Find the length of the diameter.
Give your answer rounded to 2 DP.
Answers
Answer:
Diameter = 2.68cm
Step-by-step explanation:
Circumference of a circle = 2πr
Circumference of a circle = 8.44cm
π = 3.14
r = ?
Circumference of a circle = 2πr
8.44 = 2 * 3.14 * r
8.44 = 6.28r
r = 8.44/6.28
r = 1.3439490445859
Approximately
r = 1.34
Diameter = 2r
Diameter = 2 * 1.34
Diameter = 2.68cm

Step-by-step explanation:
A power company calculates a person's monthly bill from the number of kilowatt-hours (kWh), x, used. The function b(x) = { 0.150, s 0.10 (x – 200) + 30, x < 200 2 > 200 determines the bill. How much is the bill for a person who uses 300 kWh in a month? O A. $60 O B. $55 C. $40 D. $45
Answers
The bill for a person who uses 300 kWh in a month is $40
How to determine the bill of the person?The piecewise function of how the power company calculates the bill is given as:
b(x) = 0.150x, x < 200
b(x) = 0.10(x - 200) + 30, x >= 200
For a person who uses 300 kWh in a month, the value of x is 300.
i.e. x = 300
By comparing the domain of the piecewise function, we make use of the following function
b(x) = 0.10(x - 200) + 30, x >= 200
Remove the domain
b(x) = 0.10(x - 200) + 30
Substitute the known values in the above equation
b(300) = 0.10(300 - 200) + 30
Evaluate the difference
b(300) = 0.10(100) + 30
Evaluate the product
b(300) = 10 + 30
Evaluate the sum
b(300) = 40
Hence, the bill for a person who uses 300 kWh in a month is $40

x + y = 100 x -y = 10
Pair of Equation
Answers
lets take
x+y=100 firstly.
then x=100-y equation (i)
Now,
x-y=10
Putting value of x from equation(i)
100-y-y=10
-2y=10-100
-2y=-90
therefore, y=45
Now,
putting value of y in equation(i)
we get
x=100-45
ie x=55
hence, x=55 & y=45
Answer:
The solution is (55, 45).
Step-by-step explanation:
Solve the system of linear equations
x + y = 100
x - y = 10
through elimination by addition / subtraction.
Combining these two equations temporarily eliminates y, leaving us with 2x = 110. Then x = 55.
Substituting 55 for x in the first equation, we get:
55 + y = 100. Subtracting 55 from both sides leaves us with y = 45.
The solution is (55, 45).

There are four points here. We look at the x-values and identify {2, 1, -2, 1]. This can be reduced to {-2, 1, 2}
Unfortunately, the input '1' shows up twice and thus the relation cannot be a function; we cannot have two different y-values for the same x-value (1).
