Answer:
f(h)=15(8)+30
8 Hours per week
Step-by-step explanation:
$30 per week means she has a start of $30, so this will be a constant.
What we want to find is how much she needs to work to earn the remaining amount, $120.
To find that we need to divide $120/15, giving us 8.
She needs to work 8 hours per week. This gives us the function
x=15(8)+30
Answer:
She will have to work 8 total hours that week.

A health club charges a $25 one-time sign-up fee and a monthly membership fee of $44 per month. Find the rate of change.
Answer:
First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.
To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.
240 = 25x + 40
subtract 40 from each side
200= 25x
divide by 25
8 = x
8 months
10 + 7r = 45
7r = 35
r = 5
5 milesStep-by-step explanation:
The rate of change is 5.
What is rate of change?The rate of change of anything is how rapidly it changes over time (ROC).
You must first create the equation
y = mx + b,
where m represents the monthly price and b represents the one-time cost. Months are represented by the number x.
We replace 240 for y and solve for x to find the total number of months at a price of 240.
40 is subtracted from either side of 240 = 25x + 40.
200 = 25x
25 divided
8 months equals 8.
10 + 7r = 45
7r = 35
r = 5
Therefore, 5 is the rate of change.

Length of QR in units = 5.83 units, which is closest to 5.8 units.
The correct option is A.
What is length of line segment?The distance between any two points is the length of the line segment joining the points.
The formula for the distance, D, between two points whose coordinates are (x₁, y₁) and (x₂, y₂)
D = √((x2 – x1)² + (y2 – y1)²)
This is called the Distance Formula.
Given,
Coordinates of points Q (8, 2) and R (5, 7)
Length of QR = Distance between point Q and point R.
D = √((x2 – x1)² + (y2 – y1)²)
D = √((5 - 8)² + (7 - 2)²)
D = √(-3² + 5²)
D = √9 + 25
D = √34
D = 5.83 units
Length of QR rounded to one decimal = 5.8 unit
Hence, 5.8 unit is closest to the length of QR = 5.83units

plz need help with this
Answer:
-4
Step-by-step explanation:
Parallel lines are lines that run across from each other but never intersect. For this to work, they must change at the same rate and have the same slant. This means parallel lines must have equal slopes; therefore, the slope of the parallel line is -4. It is also important to note that parallel lines must have different y-intercepts, or they would just be the same line.

A student would like to estimate the proportion of students at his school who have lunch during period 4. To do so,
he selects a random sample of 40 students and finds that 30% of them have period 4 lunch. Later, he goes to the
guidance office and finds that of the 380 students at this school, 25% of them have period 4 lunch. Which of the
following properly describes the number, 25%?
sample
statistic
population
parameter
Yeah
Answer:
D
As we are getting the 25% from the whole population of 380 students, therefore this is a population proportion which is a parameter. Note that we get parameter from population and statistic from the sample.
Step-by-step explanation:
The property parameter describes the number, 25% because 25% from a population of 380 students, this is a population proportion that may be used as a metric option (D) parameter is correct.
What are population and sample?It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.
We have:
Number of samples = 40
30% of them have period 4 lunch.
Total population = 380
25% of them have period 4 lunch.
Because we're collecting 25% from a population of 380 students, this is a population proportion that may be used as a metric.
We collect parameters from the population and statistics from the sample.
Thus, the property parameter describes the number, 25% because 25% from a population of 380 students, this is a population proportion that may be used as a metric option (D) parameter is correct.

Please who steps.on how to solve.
Answer:
51°
Step-by-step explanation:
An inscribed angle is half of the arc it intercepts. This means that arc QR is twice m<QTR or 78°.
Since <QSR is a central angle, it equals the arc it intercepts. This means m<QSR equals arc QR which is 78°.
We can say that QS equals to RS because they are both radii, and radii of the same circle are equal. This means triangle QSR is isosceles.
Let <QRS equal x. Because of base angle theorem, <SQR would also be equal to x. Since the angles in a triangle add up to 180, we can write an equation to model the situation:
m<QRS + m<SQR + m<QSR = 180
We can substitute the values we have:
x + x + 78 = 180
2x = 102
x = 51
Since <QRS is equal to x, it is 51°

Answer:
Number of cake Lorna decorate[if number of cake is 4] = 14 cakes
Step-by-step explanation:
Given expression;
d = 2c + 6
Find:
Number of cake Lorna decorate[if number of cake is 4]
Computation:
We know that
Number of cake = C
Number of decorate cake = d
So,
Number of cake = 4 cakes
Using given equation to find value of 'd'
d = 2c + 6
d = 2[4] + 6
d = 8 + 6
d = 14
Number of cake Lorna decorate[if number of cake is 4] = 14 cakes

a triangle has three sides 19cm 12cm and 16 cm. is it a right triangle
Answer:
Step-by-step explanation:
A right triangle has one angle of 90.
If you add up all the angles ;
19+12+16= 47
It equals 47 so this is not a right triangle.
If it it is less than 90, it is an acute angle.
Therefore this angle is an acute triangle.
