Step-by-step explanation:
Evaluate 2 ∙ (8 + 4) using the steps of order of operations: Add 8 and 4 and multiply the sum (12) by 2 and you get 24.
Evaluate 15 + 6 ∙ 3 using the steps of order of operations: multiply 6 by 3 and add the product (18) by 15 and you get 33.
Sherry thinks 7, 7 and 12 are side lengths of a right triangle. Do you agree or disagree? Justify your reasoning. PLEASE NOW!!!! PLEASE!!!!!!
Answer:
disagree
Step-by-step explanation:
If the triangle is right, then the square of the longest side must equal the sum of the squares on the other 2 sides.
longest side = 12 ⇒ 12² = 144
7² + 7² = 49 + 49 = 98
Since 144 ≠ 98 then triangle is not right

hope this helps u!
Answer:
your answer is 45
Explanation:
The Greatest Common Factor (GCF) for 90 and 135, notation CGF(90,135), is 45.
The factors of 90 are 1,2,3,5,6,9,10,15,18,30,45,90;
The factors of 135 are 1,3,5,9,15,27,45,135.
So, as you can see, the Greatest Common Factor or Divisor is 45, because it is the greatest number that divides evenly into all of them.

The population of a city is growing at an uninhibited rate of 1.6% per year. The city's initial population was 125,000. How long will it take the population of that city to reach 175,000? Round to the nearest tenth.
a. 56.5 years
b. 21.0 years
c. 9.1 years
d. 37.8 years
Answer:
B
Step-by-step explanation:
First we find how much of 125000 is increasing. Once we do that, it is basically a slope intercept equation.
We know that 1.6 percent of 125000 is 2000.
We know have y=2000x+125000
There are two ways to solve this, either plug in the given values of a, b, c, and d into the equation and see if it equal 175000, or we we set the equation equal to 175000
If we do the second easiet option, we have
2000x+125000=175000 Use inverse operations
2000x=50000
x=25, or roughly option b.
If we plug in b, we get y=2000(21)+125000 or 167000
21.0 years will it take the population of that city to reach 175,000.
What is population growth rate?Population growth rate is the change in the number of individuals over a specific period of time. Population growth rate can be interpreted over any time period.
Given
Population of a city is growing at an uninhibited rate of 1.6% per year.
The city's initial population was 125,000.
Based on the given conditions
[tex]125000.(1+0.016)^{x} =175000[/tex]
⇒ [tex]125000.(1.016)^{x} =175000[/tex]
⇒ [tex](1.016)^{x} =\frac{175000}{125000}[/tex]
⇒ [tex](1.016)^{x} =\frac{7}{5}[/tex]
⇒ [tex]x=log_{1.016} \frac{7}{5}[/tex]
⇒ [tex]x=log_{\frac{127}{125} } \frac{7}{5}[/tex]
⇒ x = 21.0
21.0 years will it take the population of that city to reach 175,000.

Find the y-intercept of the following equation. Simplify your answer.
y = x + 4/7
Answer:
[tex]\frac{4}{7}[/tex]
Step-by-step explanation:
The y -intercept of the given line is [tex]\frac{4}{7}[/tex];
y = x + [tex]\frac{4}{7}[/tex]
The equation of any line is y = mx + c;
y and x are the coordinates
m is the slope
c is the y-intercept
y = x + [tex]\frac{4}{7}[/tex]
So [tex]\frac{4}{7}[/tex] is the y-intercept

Answer:
$132.63
Step-by-step explanation:
$49.13 - ($32.50 × 2)
$49.13 - $65 = $-15.87
$-15.87 + ($74.25 × 2)
$-15.87 + $148.50

how do you find the domain on this type of graph
Answers:
Domain: [tex]x \ge -5[/tex]
Range: [tex]y \ge -2[/tex]
========================================
Explanation:
The domain is the set of all allowed x values of a function. The point on the very left shows that x = -5 is the smallest value possible. So this means the domain consists of x values such that x = -5 or x > -5. We shorten that to [tex]x \ge -5[/tex]
------------------
The range is the set of possible y outputs. The lowest point is when y = -2 meaning that [tex]y \ge -2[/tex] is the range (so y can be -2 or larger).
