Answer:
The number= 15 or 5/2
Step-by-step explanation:
(8x-20)(2x-30)=0
16x^2-240x-40x+600=0
16x^2-280x +600 =0
divide by 8
2x^2-35x+75=0
2x^2-30x-5x+75=0
2x(x-15)-5(x-15)=0
(x-15)(2x-5)=0
x=15 OR 5/2

A realtor has been told that 43% of homeowners in a city prefer to have a finished basement. She surveys a group of 300 homeowners randomly chosen from her client list. Describe the sampling distribution model of the proportion of homeowners in this sample who prefer a finished basement. Round to the nearest tenth
The sample who prefer a finished basement is 126 homeowners
Percentages and ratiosGiven the following parameters
The total number of people surveyed = 300 homeowners
If a realtor has been told that 43% of homeowners in a city prefer to have a finished basement, the sample of owners that prefer a finished basement is expressed as:
Sample of owners = 43% of 300
Sample of owners = 0.43 * 300
Sample of owners = 126
Hence the sample who prefer a finished basement is 126 homeowners

Find the area of a circle with radius,
r
= 6.16m.
Give your answer rounded to 2 DP.
Answer ≈ 119.21m
Step-by-step explanation: Plugging the radius into the equation for the area of a circle equals 119.209618 which rounds to 119.21.

angle c and angle d are supplementary angles.if the measure of angle d is 80 degress,what is the measure of angle c
Answer:
C = 100
Step-by-step explanation:
Supplementary angles equal 180 degrees
180 - 80 = 100
Answer:
m∠C = 100°
Step-by-step explanation:
Supplementary angles are angles that add up to 180°. We are given m∠D as 80°.
This means that c + 80 = 180Step 1: Subtract 80 from both sides.
[tex]c+80-80=180-80[/tex] [tex]c=100[/tex]Therefore, the answer is 100°.

The pattern 0, 15, 30, 45, ________, follows the "add 15" rule. Use words to describe the rule and write the next term.
Answer:
The next term in the sequence can be found by adding 15 to the previous term in the sequence.
Therefore, the next term = 45 + 15 = 60
This is a arithmetic sequence having common difference d=15
If you want next term add 15to the previous one
Like
0+15=1515+15=30Next term is
45+15=60Please help, will mark brainliest :)

One leg of a 45°-45°-90° triangle measures 15/2 inches What is the length of the hypotenuse?
Answer: 7.5sqrt(2)
Step-by-step explanation:
Given f(x) = 3x-1 and g(x) = 2x-3, for which value of x does g(x)=f(2)?
Answer:
x = 4
Step-by-step explanation:
To see when g(x) = f(2)
First, find f(2)
f(2) = 3(2) - 1 = 5
Now g(x) = 2x-3 = f(2) = 5
2x - 3 = 5
Adding 3 to both sides
2x = 8
Dividing 2 on both sides
x = 4

Which function has a constant additive rate of change of –1/4?
A coordinate plane with a straight line with a negative slope. The line passes through (negative 2, 2) and (2, 1).
A coordinate plane with a curved line passing through (negative 1, 2), (0, negative 1), the minimum (2, negative 2), and (4, negative 1).
A two column table with five rows. The first column, x, has the entries, 20, 21, 22, 23. The second column, y, has the entries negative 1, negative 1.5, negative 2, negative 2.5.
A two column table with five rows. The first column, x, has the entries, negative 12, negative 11, negative 10, negative 9. The second column, y, has the entries, 7, 11, 14, 17.
Answer:
The first coordinate plane has a constant additive rate of change of -1/4
Step-by-step explanation:
Additive rate of change is determined using the slope formula:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
It must be applied to all of the coordinates given, as sometimes, answer options will have the right slope for the first few options but then change it later in the list. Remember that this is a constant rate of change; it must be the same throughout all of the coordinates.
The first coordinate plane with (-2, 2) and (2, 1) is
[tex]m=\frac{1-2}{2-(-2)} =-0.25[/tex]
so this is the answer. I encourage you to look below to see why the others are not the answer, as there are some tips throughout the rest of my response.
The second plane is a curved line, and this means that it is a function with some kind of exponent or log (judging by the shape, it is probably a quadratic function). Regardless, it will not have a constant change from point to point because of the curve. This is not the answer for those reasons.
The first table is linear (with a constant slope), so that meets the first requirement. The slope, however, is -1/2, so it is not what we are looking for. This is also not the solution.
The last table has a positive slope of 3.3, so this does not fit what we want from an answer.
Hope this helps :)

A coordinate plane with a straight line with a negative slope. The line passes through (negative 2, 2) and (2, 1).

Which of the following is equivalent to cos 32°?
a cos 58°
b cos 68°
c sin 32°
d sin 58°
Answer: Choice D
Step-by-step explanation:
cos(32) = 0.8480480962
cos(58) = 0.5299192642
cos(68) = 0.3746065934
sin(32) = 0.5299192642
sin(58) = 0.8480480962
Cos(58) = sin(32)
Cos(32) = sin(58)

There are 5 pencil-cases on the desk. Each pencil-case
contains at least 10 pencils, but not more than 14 pencils.
Which of the following could be the total number of pencils in
all 5 cases?
Answer:
Choose the numbers in the choices that are 50, 70, or any integer in between 50 and 70.
Step-by-step explanation:
Minimum number of pencils: 5 × 10 = 50
Maximum number of pencils: 5 × 14 = 70
The number of pencils ranges from 50 to 70. All integers 50, 70 and in between 50 and 70 are possible.
Choose the numbers in the choices that are 50, 70, or any integer in between 50 and 70.
