- The number is at most four-fifths.
- The number is at least four-fifths.
- The number is at most negative four-fifths.
Answers
Answer:
The first one is correct.
Step-by-step explanation:
Your equation is 3n ≥ 4+8n
Simplify:
3n ≥ 4+8n
-8n -8n
-5n ≥ 4
-5 -5 Dividing by negative 5
n ≤ - 4/5 sign was flipped because you divided by a negative number.

A total of 800 advertisements were sold for a certain magazine. If 80 percent of the first 150 sold in color, 40 percent of the next 400 sold in color, and 80 percent of the next 80 were sold in color, what percent of the 800 magazines were sold in color?
Answers
Explanation:
First you have to find how many of each group were sold. To do this you multiply the number given(150, 400, or 80) by the percent as a decimal.
So for the first 150 you multiply 150 by .80
150*.8=120
The next 400 would be 400*.4=160
The next 80 would be 80*.8=64
Now you add up the totals found.
120+160+64=344
Finally divide this number by the total 800 and multiply the decimal by 100 to convert it to percent.
344/800=.43
.43*100=43
43 percent
Answer:60 %

The interest with the given principal, time period and rate of interest is $3076.
Given that, principal=$50,000, time period =6 years and rate of interest =1%.
What is the compound interest?Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
The formula used to find the compound interest is
Amount =Principal(1+r/100)^t
= 50000(1+1/100)^6
= 50000(1.01)^6
= 53076
So, interest =Amount-Principal
= $3076
Therefore, the interest with the given principal, time period and rate of interest is $3076.

Find the percent decrease. Round to the nearest percent.
From 85°F to 60°F
Answers
Answer:
Percent Decrease ≈ 30%
Step-by-step explanation:
Let's first find what part of 85 is 60
60/85 = 12/17
12/17 = 0.70588 ≈ 0.70 = 70%
Now, since 85 is 100%, and 60 is 70% of 85, the percent decrease is :
100% - 70% = 30%

BRAINLIEST!!
Answers
Answer:
m < S = 40°
Step-by-step explanation:
According to the Triangle Exterior Angle Postulate, the measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
The exterior angle is m < R = 140°. In reference to the Triangle Exterior Angle Postulate, the sum of the measures of < T and < S must equal 140°.
Given m < T = (8x + 4)°
m < S = (3x + 4)°
We can set up the following equality statement to solve for the value of x:
m < R = m < T + m < S
140° = (8x + 4)° + (3x + 4)°
Combine like terms:
140° = 11x + 8
Subtract 8 from both sides:
140° - 8 = 11x + 8 - 8
132° = 11x
Divide both sides by 11:
132°/11 = 11x/11
12 = x
Substitute the value of x into the equality statement to verify whether it is the correct value:
140° = (8x + 4)° + (3x + 4)°
140° = [8(12) + 4]° + [3(12) + 4]°
140° = (96 + 4)° + (36 + 4)°
140° = 100° + 40°
140° = 140° (True statement. Therefore, the correct value for x = 12).
Therefore, m < S = (3x + 4)° = [3(12) + 4]° = 40°

What is the slope of a line passing through two points?The slope of a line passing through points [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] is
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Given two points are [tex]A(-1, -4)[/tex] and [tex]B(2, 5)[/tex].
Therefore, the slope of a line passing through those two points is
[tex]m_{1} = \frac{5 - (-4)}{2-(-1)}[/tex]

find all the zeros of the quadratic function y=x²-9x+20
Answers
Answer:
Roots: x = 5; x = 4
Step-by-step explanation:
Given the quadratic equation, x² -9x + 20 = 0
where a = 1, b = -9, and c = 20
Determine the nature and number of solutions based on the discriminant, b² - 4ac:
b² - 4ac = (-9)² - 4(1)(20) = 1
Since b² - 4ac > 0, then it means that the equation will have two real roots.
Use the Quadratic Formula:
[tex]x = \frac{-b +/- \sqrt{b^{2} - 4ac} }{2a}[/tex]
[tex]x = \frac{-(-9) +/- \sqrt{(-9)^{2} - 4(1)(20)} }{2(1)}[/tex]
[tex]x = \frac{9 +/- \sqrt{1}}{2}[/tex]
[tex]x = \frac{9 + 1}{2}; x = \frac{9 - 1}{2}[/tex]
[tex]x = \frac{10}{2}; x = \frac{8}{2}[/tex]
x = 5; x = 4
Therefore, the roots of the quadratic equation are: x = 5; x = 4.
