Sharon made $45 in interest by placing $500 in a savings account with simple interest for 1 year. What was the interest rate?
Answer: The interest rate was 9%.
Step-by-step explanation:
If principal amount P is invested at the rate of r percent with simple interest(I) for t years, the formula to find rate :
[tex]R=\dfrac{I\times100}{P\times t}[/tex]
As per given,
P = $ 500, I = $45, t = 1 year
Substitute values in formula , we get
[tex]R=\dfrac{45\times100}{500\times1}\\\\\Rightarrow R=9\%[/tex]
Hence, The interest rate was 9%.

A car travels a distance of 190 miles in a time of 3.4 hours.
What is its average speed rounded to 1dp?
Answer:
55.9 mph
Step-by-step explanation:
190/3.4 = 55.88 mph rounded to one dp = 55.9 mph
A car travels a distance of [tex]190[/tex] miles in a time of [tex]3.4[/tex] hours, then its average speed will be [tex]56[/tex] miles per hour.
What is average speed ?Average speed is speed is the total distance traveled by the car in a particular time of interval.
Average speed [tex]=\frac{Total \ Distance}{Total \ Time}[/tex]
We have,
Distance [tex]=190[/tex] miles
Time[tex]= 3.4[/tex] hours
So, Using the above given formula,
Average speed [tex]=\frac{Total \ Distance}{Total \ Time}[/tex]
[tex]=\frac{190}{3.4}[/tex]
[tex]=56[/tex] miles per hour
So, the average speed of car is [tex]56[/tex] miles per hour which is find out using the above given formula.
Hence, we can say that if a car travels a distance of [tex]190[/tex] miles in a time of [tex]3.4[/tex] hours, then its average speed will be [tex]56[/tex] miles per hour.

find the size of angle X.
The size of angle x is 115.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
From the figure,
The whole complete angle is 360.
This means,
164 + 81 + x = 360
Solve for x.
164 + 81 + x = 360
245 + x = 360
x = 360 - 245
x = 115
Therefore,
The size of angle x is 115.

Three bananas and two pears cost 95p.
Five bananas and three pears cost £1.51
Find the cost of ten bananas and ten pears.
Answer:
Cost of ten bananas and ten pears is £ 3.90
Step-by-step explanation:
As three bananas and two pears cost 95 p and five bananas and three pears cost £ 1.51 or 151 p ,
subtracting former from latter, we get
two bananas and one pear cost 151 p − 95 p = 56 p
and doubling four bananas and two pear cost 56 p × 2 = 112 p
Hence, one banana costs 112 p − 95 p = 17 p .
and two bananas cost 17 p × 2 = 34 p
and hence one pear costs 56 p − 34 p = 22 p
Hence cost of ten bananas and ten pears is
10 × 17 p + 10 × 22 p = 170 p + 220 p = 390 p = £ 3.90

We have a side that is opposite our angle,
and we have the hypotenuse. Which ratio
will we use?
Answer:
Sine
Step-by-step explanation:
Using the acronym SOHCAHTOA, we can see that Sine (S) should be used.
SOH represents Sine, Opposite, Hypotenuse.
Since we are only given the opposite side and hypotenuse, the sine ratio should be used, which is opposite / hypotenuse
So, sine will be used.

Answer:
52 in.
Step-by-step explanation:
Let the width = x.
The length is x + 18.
perimeter = 2(L + W)
244 = 2(x + x + 18)
122 = 2x + 18
2x = 104
x = 52
The width is 52 in.

Find all angles, 0°< A<360°, that satisfy the equation below, to the nearest tenth
of a degree (if necessary).
3 tan A+75 = 0
Answer:
143.3 degrees and 323.3 degrees
Step-by-step explanation:
Given the equation
3tanA +√5 = 0
3tanA = -√5
tanA =-√5/3
tanA = (-0.7454)
A = arctan(-0.7453)
A = -36.699
Since tan is negative in 2nd and 4th quadrant
A = 180 - 36.699
A = 143.3 degrees
In the fourth quadrant
A = 360 - 36.699
A = 323.3degrees
Hence the value of A that satisfies the equation are 143.3 degrees and 323.3 degrees

What is the inverse function (equation) of f(x) = 6x - 5 ?
Step-by-step explanation:
Given
f(x) = 6x - 5
f^-1(x) = ?
Let
y = f(x)
y = 6x - 5
Interchanging the roles of x and y we get
x = 6y - 5
6y = x + 5
y = ( x + 5 ) / 6
So therefore f^- 1(x) = (x + 5) / 6
