Answers
Answer:
(x + 60 + 30) * 2 = 200
(x + 90) * 2 = 200 multiply 2 inside parentheses
2x + 180 = 200 move 180 to the other side with changing it's sign
2x = 20 multiply by 2
x = 10 here is the answer
Step-by-step explanation:
Perimeter = (length + width) * 2

A scuba diver descends in the water at a rate of 2312 feet per minute for 2.6 minutes. He immediately changes course when he sees a large fish and ascends at a rate of 28 feet per minute for 2 minutes.
What is the scuba diver's position relative to sea level after the 4.6 minutes?
Enter your answer as a decimal in the box.
ft
Answers
2312 FPM for 2.6 minutes
2312 x 2.6 = 6011.2
28 FPM for 2 minutes
28 x 2 = 56
6011.2 descend
55 ascend
0-6011.2 = -6011.2

Point U on a graph is located at (4,8), Point V on the same graph is located at (12, 14).
Which point lies on Line UV?
A. ( 7 , 12 )
B. ( 10 , 14 )
C. ( 16 , 22 )
D. ( 20 , 20 )
Answers
Answer:
D
Step-by-step explanation:
gradient is change in y/change in x
gradient of UV = 14-8/12+4=3/4
use equation y=mx+c where y is the y coordinate, m is the gradient, x is the x coordinate and c is the y intercept
use one of the coordinates of U or V, I'll use (4,8)
[tex]y = mx + c[/tex]
[tex]8 = \frac{3}{4} (4) + c[/tex]
[tex] 8 = 3 + c[/tex]
c is 5
the equation for UV is
[tex]y = \frac{3}{4} x + 5[/tex]
insert each X coordinate given in the question to see if it gives the same y coordinate
when x is 20, y is also 20 so the answer is D
Bots have answered this for the past two times but I still need help. The question is below.
Answers
Answer:
a. False
b. True
c. True
d. I think it's true
e. False
Step-by-step explanation:
a. The unit rate is 19.75 gallons per minute
b. It is true because when x=0 y is also equal to 0, therefore it passes through the origin
c. 19.75 is about 20, and 20 multiplied by 5 is 100
d. Like I said before I don't know but I hope you get it correct ._.
e. When x=8 the equation would be 19.75*8 which is equal to 158 not 150

Step-by-step explanation:
Mr. Quick bought a new computer system. The regular price was $1,580, but he got a 15% discount. How much did he actually pay?
You need to turn 15% into a decimal.
Move the decimal point to the left 2 spaces.
15 ---> 1.5 ---> 0.15
Now multiply 0.15 by $1,580.
0.15 × $1,580
Which is $237.
Now subtract $1580 - $237.
Which is $1343.
Answer:
$1580*15/100=$237that is discount rate.
$1580-237=$1343 actually pay

11.50 + 1.15x = 12.65
11.50 - 11.50 + 1.15x = 12.65 - 11.50
➗ 1.15x = 1.15 ➗ what does x equal? Please explain in great detail how you figured this out also replace the = with the proper inequality sign and explain how you did that as well.
Answers
Answer: the answer is x= 1
Step-by-step explanation:
So we are dealing with 11.50 - 11.50 + 1.15x = 12.65 - 11.50
our first step is Simplify both sides of the equation so:
11.5 + -11.50 + 1.15x = 12.65 + -11.50 turns into:
(1.15x) + (11.5+ -11.5)= (12.65 + -11.5)
**we know 11.5 + -11.5 will cancel each other since they are opposite**
so it will be 1.15x= 1.15
now the very last step is to divide 1.15x on both sides which gives us 1
Explain, in detail, how you know if these are equivalent.
Answers
Answer:
they are equivalent.
Step-by-step explanation:
to find equivalent fractions, we need to multiply the numerator and denominator of the first fraction by the same number. this creates an equivalent fraction. 5 goes into 15 3 times, and 8 goes into 24 3 times. this shows that if we multiply both the numerator and denominator of the first fraction by 3, then we end up with the second fraction, proving that they are the same. hope this helps!

Two linear functions are represented in different formats.

Function 2: (image below)
Which statements are true?
Select each correct answer.
Function 1 has a greater rate of change than function 2.
Function 2 has a greater rate of change than function 1.
Function 1 has a greater y-intercept than function 2.
Function 2 has a greater y-intercept than function 1.
Answers
Answer:
Function 1 has a greater Y intercept than that of function 2
Step-by-step explanation:
Y intercept can be found by replacing x by 0 or
x = 0 0f the given function.
in this case Function 1 has a Y intercept of 5 when x =0
on the other hand, function 2 crosses the y axis once at -1 which is the y intercept.
you can now clearly see that
y = 5 > y = -1
---> 5>-1
so that's why we conclude that 1 has a greater Y intercept.
3/4c-7/12+7/24c+2/3-1/6c
simplify the expression
Answers
Explanation: separate the c terms and the non-c terms. 3/4c + 7/24c - 1/6c = 7/8c
-7/12 + 2/3= 1/12
therefore, it’s 7/8c + 1/12
The simplification of the given expression (3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c is (21/12)c + 1/12.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
A statement expressing the equality of two mathematical expressions is known as an equation.
As per the given expression,
(3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c
Combined likely terms,
⇒ (3/4)c + (7/24)c - (1/6)c - 7/12 + 2/3
⇒ (3/4 + 7/24 - 1/6)c + 2/3 - 7/12
⇒ [(18 + 28 - 4)/24]c+ (8 - 7)/12
⇒ (42/24)c + 1/12
⇒ (21/12)c + 1/12
Hence "The simplification of the given is (21/12)c + 1/12".
