If I do my maths homework at a rate of 1.6 questions per minute, it will take me 47 minutes to complete. What rate is needed to complete it in 34 minutes?
Give your answer correct to 1 decimal place.
Answer:
Step-by-step explanation:
reqd. rate=(1.6)×47÷34≈2.2 questions per minute.
The required rate to complete the question in 34 minutes is given as 2.2 questions per minute.
What is the rate of change?Rate of change is defined as the change in value with rest to the time is called rate of change.
As mentioned in the question, in homework rate of doing questions is 1.6 questions per minute.
It took 47 minutes to complete the whole expression,
Total questions in the homework given by,
Total question = rate × time
Total question = 1.6 × 47
Total questions ≈ 75 questions
Now,
If the time to complete the question is 34 minutes, the rate required is given by,
Rate = total question/time
Rate = 75/34
rate = 2.2 questions per minute.
Thus, the required rate to complete the question in 34 minutes is given as 2.2 questions per minute.

The map below shows the locations of the houses of Maria Reese and Paul.what are the coordinates of Steve's house who lives 2 miles form Paul and 1 mile form Reese. Please help
Answer:
Coordinates of Steve's House are S (3,2)
The required coordinate of the Steves's house is (3,2).
The map below shows the locations of the houses of Maria Reese and Paul, coordinates of Steve's house who lives 2 miles from Paul and 1 mile from Reese is to be determined.
Coordinate, is represented as the values on the x-axis and y-axis of the graph
Here,
Since Steve's house lives 2 miles from Paul's, So the Y coordinate of Steve's house will raise to 2 more than the Y coordinate of Paul, So Y = 0 + 2 = 2
Now, Steve's house lives 1 mile from Reese x coordinate of Steve's house will raise to 1 more than the x coordinate of Reese, So X = 2 + 1 = 3
Thus, the required coordinate of the Steves's house is (3,2).

what is the value of x? Help asap please
Answer:
x = 30
Step-by-step explanation:
A triangle's angles add up to 180
Also, angles on a straight line add up to 180
180-100 = 80
80+70=150
180-150=30
Answer:
x = 30
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
100° is an exterior angle of the triangle, then
x + 70 = 100 ( subtract 70 from both sides )
x = 30

If the measure of angle 1 is 110° and the measure of angle 3 is (2x+10)", what is the value of x?
x=50
Step-by-step explanation:
angle 1 and 3 are corresponding angles that menas they equal the same
so set it up like this 2x+10=110 solve for x
move over the 10, subtract 10 from 110 you get 100 and divide by 2
you get 50.
=================================================
Explanation:
Angles 1 and 3 are vertical angles which are congruent.
angle 1 = angle 3
110 = 2x+10
2x+10 = 110
2x = 110-10
2x = 100
x = 100/2
x = 50

Use proportional reasoning to determine the value of a in the proportion shown below.
a=1
a=25
a=10
a=15
Answer: a = 10
Step-by-step explanation:
3/5 = a + 5/25
Multiply both sides by 25 to get rid of it:
3/5 * 25 = 25(a + 5) /25
15 = a + 5
a = 15 - 5
a = 10
. The graph below shows the amount of money spent on a homeowners insurance bill and the period of time passed. Based on the information in the graph, how much will the Jones family spend on homeowners insurance after 9 months?
Answer:
$450
Step-by-step explanation:
First, find an equation that represents the proportional relationship between number of months (x) and amount spent (y).
A proportional equation can be represented in the form, y = kx, where,
k = constant of proportionality = y/x
Using a point on the line, (1, 50),
k = 50/1 = 50.
Substitute k = 50 into y = kx
The equation would be:
y = 50x
After 9 months (x), they would pay the following:
Substitute x = 9 into y = 50x
Thus:
y = 50(9)
y = 450

What is special about y coordinate that goes with the x coordinate of 1on a proportional gragh
Answer:
The first coordinate (usually the x-coordinate) is called the domain and the second (usually the y-coordinate) is called the range. If tou remember from earlier chapters the domain contains values that correspond to the independent variable whereas the range contains values corresponding to the dependent variable.
