Please help! This assignment was due yesterday, May the 12, but I have yet to get it done.
Answer:
x>-1
Step-by-step explanation:
So, we want to isolate the variable which is X. To do so, we must add 4 on both sides.
x-4+4>-5+4
x>-1
Next comes the graphing:
This equation means that x can be all values that are LARGER THAN -1. The line would start from -1, but it wouldn't include negative one, and stretch all the way to positive infinity (to the right).

What is 67,795 rounded to the nearest thousand?
Answer:
68 000
Step-by-step explanation:
When we round to the nearest thousand, we have to look which thousand is closer to the value. So in our case 67795 is 205 away from 68 000 and is 795 away from 67000. From this we know that 68 000 is closer, therefore if we round 67 795 to the nearest thousand we will get 68 000.

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.

A survey shows that 7 out of 8 customers are satisfied with the food served at Big Joe BBQ.
Assuming the restaurant had 176 customers yesterday, how many customers probably left unsatisfied?
Answer:
22
Step-by-step explanation:
First, we need to find 1/8 of 176, which is basically 176/8 = 22.
22 = 1/8
154 = 7/8
So 154 customers left satisfied and 22 unsatisfied.

Two angles are vertical angles. One angle is ( 8x + 15 ) and the other angle is 143. Solve for x.
Answer:
x = 16
Step-by-step explanation:
Verticle angles are always congruent, so:
(8x + 15) = 143
Now, we can solve to isolate x:
8x + 15 - 15 = 143 - 15 (subtract 15 from both sides)
8x/8 = 128/8 (divide both sides by 8)
x = 16
You can always plug in the value of x to the original equation to check your answer:
8(16) + 15 = 143
the market price of an article is rupees 1500 find the price after allowing the discount of 10%
Answer:
Step-by-step explanation:
1500 x .10= 150
1500 - 150 = 1350
=1350 is the price after following the discount of 10%
Answer:
1350
Step-by-step explanation:
Market price = 1500
Discount = 10%
Price of article after allowing discount = 1500 - (1500* 10/100)
=1500 - 150
= 1350

The coordinates of the endpoints of QR are
Q (8, 2) and R (5, 7) ).
Which measurement is closest to the length of QR

A 5.8 units
B 5 units
C 4 units
D 3.9 units
Answer: I just did the test so the answer is A. 5.8 units
Step-by-step explanation: hope this help thx for the points :D
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

7 grade math Area of compound figures with triangles, semicircles, and quarter circles
Answer:
area = 250.04 km^2
Step-by-step explanation:
In the image, we have the next figures.
One quart of a circle, with radius R = 12km
A large rectangle, with length L = 13km and width = 9 km
(to find the width of this rectangle, look at the bottom, we have a part of 5km, and then we have the small rectangle with a width of 4km, then 4km + 5km = 9km)
And finally, a smaller rectangle with length L = 5km and width W = 4km
Now, the general rules for each figure are:
The area of a circle of radius R, is
A = pi*R^2
with pi = 3.14
Here we have the fourth part of a circle with a radius R = 12km
Then the area of that part is:
area = (1/4)*3.14*(12km)^2 = 113.04 km^2
And the area of a rectangle of length L and width W is:
A = W*L
Then, the area of the larger rectangle is:
A' = 9km*13km = 117 km^2
And the area of the smaller rectangle is:
A'' = 4km*5km = 20km^2
The complete area of the figure is:
area = A + A' + A'' = 113.04 km^2 + 117 km^2 + 20km^2 = 250.04 km^2

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.

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.
