Write the phrase as a unit rate.
$13.50 for 3.6 lb
Alb
Please help FAST
Answer:
$3.75/lb
Step-by-step explanation:
First, let's set up a proportion. The top number represents the cost, while the bottom number represents how many pounds. In order to get a unit rate, we need to figure out how much it costs for 1 pound.
[tex]\frac{13.5}{3.6} =\frac{x}{1}[/tex]
Now, cross multiply. To cross multiply, you would multiply 13.5 by 1 and 3.6 by x.
[tex]13.5 * 1 =13.5\\3.6*x=3.6x[/tex]
Set these two equal to each other.
[tex]13.5=3.6x[/tex]
Divide both sides by 3.6 to get x.
[tex]\frac{13.5}{3.6} =\frac{3.6x}{3.6}\\x=3.75[/tex]
For unit rates, you have to write your answer as per unit. To do that, put a slash next to your answer, and then your unit.
$3.75 / lb (unit)

What is the value of (–3 + 3i) + (–2 + 3i)?
–5 – 6i
–5 + 6i
5 + 6i
5 – 6i
Answer:
-5+6i
Step-by-step explanation:
We have given two complex numbers (-3+3i) and (-2+3i)
We need to simplify the given expression
(-3+3i) + (-2+3i) for simplification we will firstly open the parenthesis we will have expression as -3+3i -2+3i it will gives us the value
-5+6i
In complex numbers we add real part with real part and imaginary part with imaginary part
We have general representation of complex number as a+ib where a is real and b is real part of imaginary.
Answer:
B is your answer.

Jen can bike 12 miles in 40 minutes. How much time will she need to bike 30 miles if her speed remains the same? PLEASE HELP QUICK
Answer: 100 minutes
Step-by-step explanation:
With the given information, we can use a proportion to figure out how long it would take for Jen to bike 30 miles.
[tex]\frac{12mi}{40min} =\frac{30mi}{x} \\[/tex]

1) A 30-ft. ladder leans against a wall so that the base of the ladder
is 10 ft. from the base of the wall. What angle does the ladder
make with the ground?
A) 70.5
B) 19.5
C) 18.4
D) 33.3
Answer:
A) 70.5
Step-by-step explanation:
cos x = adjacent side/ hypotenuse
cos x = 10/ 30
cos x = 0.3
cos 70 = 0.3420
cos 71 = 0.3256
x = 70.5

Tom is 77 inches tall and shrinking at a rate of 0.75% every eyar. How tall will he be after 15 years?
Whats the exponential function
Answer:
The exponential funtion is "height(n) = 77*(0.9925)^n". After 15 years he is 68.7778 inches.
Step-by-step explanation:
Since Tom's initial height is 77 inches. After one year:
height(1) = 77*(1 - 0.0075) = 77*0.9925
After two years:
height(2) = height(1)*(0.9925) = 77*0.9925*(0.9925) = 77*(0.9925)²
After three years:
height(3) = height(2)*0.9925 = 77*(0.9925)²*0.9925 = 77*(0.9925)³
And so on, therefore the expression that represents his height is:
height(n) = 77*(0.9925)^n
Where n is the number of elapsed years. For 15 years we have:
height(15) = 77*(0.9925)^(15) = 68.7778 inches
The exponential funtion is "height(n) = 77*(0.9925)^n". After 15 years he is 68.7778 inches.

What value of x is in the solution set of 8x - 6 > 12 + 2x?
ܟ
ܢܐ ܘ ܚ ܗ
Answer:
x > 3
Step-by-step explanation:
8x - 6 > 12 + 2x
1. add 6 to both sides.
8x > 12 + 2x + 6
2. Simplify 12 +2x + 6 to 2x + 18.
8x > 2x + 18
3. Subtract 2x from both sides.
8x - 2x > 18
4. Simplify 8x - 2x to 6x.
6x > 18
5. Divide both sides by 6.
x > 18/6
6. Simplify 18/6 to 3.
x > 3
A survey will ask people if they want
more stop signs near a school. Which
group would be probably be biased
against this idea?
A students
B teachers
C driver
Answer:
I believe the answer is C. Driver.
Step-by-step explanation:
The driver is the person who has to pass by the school everyday. This means they would have to take out extra time because of the stop signs, so they would be against this.

Complete the equation of the line whose slope is -2 and y-intercept is (0,-8)
y=
Answer:
y = -2x - 8
Step-by-step explanation:
We want to find the slope-intercept form of this equation. Slope-intercept form is denoted by: y = mx + b, where m is the slope and b is the y-intercept.
We already know that the slope is -2, so that means m = -2.
We also know the y-intercept (or the point where the line crosses the y-axis) is (0, -8), which means b = -8.
Thus, our equation is: y = -2x - 8.

y=-2x-8 this should be right i had this same problem before :)
