Answer:
Follows are the solution to these questions:
Step-by-step explanation:
For point a:
Let the number is = x then,
equation / mapping function:
[tex]\to (x+22.5) \times 2=y\\\\[/tex]
For point b:
Calculating the inverse function:
[tex]\to x = \frac{y}{2} -22.5\\\\[/tex]
now we change the value of x and y so, it will gives the inverse function in standard parameters:
[tex]\to y = \frac{x}{2} -22.5\\\\[/tex]
Least Value {15, 12, 21, 18, 25, 11, 17, 19, 20}
Answer:
11
Step-by-step explanation:
The number with the last value in this data set is 11. All the other numbers are greater than it in terms of numerical value. Imagine if all the numbers were represented through pennies. 11 would have the least amount of pennies.

A line that includes the point (1, 10) has a slope of 6. What is its equation in slope-intercept
form?
Answer:
y = 6x + 4Step-by-step explanation:
The point-slope form of the equation that describes the line with a slope of m and including the point (x₀, y₀) is: y - y₀ = m(x - x₀)
m = 6
(1, 10) ⇒ x₀ = 1, y₀ = 10
Therefore:
y - 10 = 6(x - 1) ← the point-slope form
y - 10 = 6x - 6 {add 10 to both sides}
y = 6x + 4 ← the slope-intercept form
What two numbers can be multiplied to make -10 and added to make -3?
-5 x 2 = -10 , -3 x 1 = -3
A scientist mixes water (containing no salt) with a solution that contains 35% salt. She wants to obtain 105 ounces of a mixture that is 15% salt. How many ounces of water and how many ounces of the 35% salt solution should she use?
Answer:
60 oz of water to add
45 oz of 35% salt solution should be used
Step-by-step explanation:
Let x = amt no. ounces in the first solution
and 105 - x = amt no. of ounces in the second solution
Ist solution contains 0% salt
2nd solution contains .35(105 - x) salt
.15(105= amt of salt in mix
So.
amt of salt in 1st solution + amt of salt in 2nd solution = amt of salt in the mix
0 + .35(105 - x) = .15(105)
Let's get rid of the fractions by multipying thru the equation by 100
35(105 - x) = 15(105)
3675 - 35x = 1575
-35x = -2100
x = 60 oz of water to add
105 - 60 = 45 oz of 35% salt solution should be used

Solve for the area using heron´s formula
9514 1404 393
Answer:
252.8 cm²
Step-by-step explanation:
The missing side of the right triangle can be found from the Pythagorean theorem:
s² = 20² -16² = 400 -256 = 144
s = 12 . . . . cm
The area of a right triangle is more easily found using the traditional area formula:
A = 1/2bh
A = 1/2(12 cm)(16 cm) = 96 cm² (left-side triangle)
The area of the triangle on the right can be found from Heron's formula. The semiperimeter is ...
s = (16 +20 +23)/2 = 29.5
The area is ...
A = √(29.5(29.5 -16)(29.5 -20)(29.5 -23)) = √(29.5·13.5·9.5·6.5)
A = √24591.9375 ≈ 156.818 . . . . . cm² (right-side triangle)
Then the total area of the figure is ...
A = 96 cm² +156.818 cm² = 252.818 cm² . . . . total area

You rent an apartment that costs $ 1400 $1400 per month during the first year, but the rent is set to go up $ 190 $190 per year. What would be the monthly rent during the 6th year of living in the apartment?
Answer:
$2540
Step-by-step explanation:
Given data
Cost per month=$1400
Increase per year=$190
Time = 6 years
Let the total rent per month be y
Hence, the expression for the monthly rent after 6 years is
y= 1400+190(6)
y= 1400+1140
y=$2540

7/52 as a mixed number
Answer:7
Step-by-step explanation:
Answer:
[see below]
Step-by-step explanation:
[tex]\frac{7}{52}[/tex] is a proper fraction. Therefore, it cannot be written as a mixed number.
If you meant [tex]\frac{52}{7}[/tex]:7 can go into 52 7 times with 3 'parts' remaining.
This means that 7 is the whole number and the fraction is 3/7.
[tex]\frac{52}{7}=7\frac{3}{7}[/tex]
Hope this helps.
Give your answer as a mixed number. 2 6/7 ÷ 2/3 =?

A cyclist cycles a distance of 44 miles in a time of 4 hours.
What is her average speed?
Answer:
11 miles an hour
Step-by-step explanation:
44 miles divided by 4 hours would equal 11 miles in one hour, meaning her average speed would be 11 miles an hour
Answer:
The average speed is 11
Step-by-step explanation:
You would have 44 on top and 4 on the bottom(44/4)
then you would divide the 4 by four and the 44 by four to get 11 miles an hour.
