Jason invests money in an account paying simple interest. He invests $160 and no money is added or removed from the investment. After one year, he has $164.80. What is the simple percent interest per year?
Answer:
The answer is 3%
Step-by-step explanation:
1.) $160 divided by $164.80 = 1.03
2.) 1.03 x 100 = 103
3.) 103 - 100 = 3
4.) 164.80 - 160 = 4.80
5.) 4.80 divided by 160 = 0.03
6.) 0.03 x 100 = 3%

A. 600-60°-60°
O B. 70°-50-70°

the angles of a triangle always equals 180 degrees, so all of them cant be the measure of the angles of a triangle except for D
Jason needs to save at least $200 by the end of the summer. He already has $40, and he has 8 weeks to save. Which inequality can he use to decide how much he needs to save each week?
Step-by-step explanation:
y=mx+b
200 = 8x + 40
Rearrange,
x = 160/8 = 20
He would need to save $20 a week
200= 20 × 8 + 40
Answer:
8x + 40 ≥ 200At least $20 each weekStep-by-step explanation:
Target amount = at least $200Jason already has = $40Time = 8 weeksSaved amount each week = xRequired inequality:

I'm assuming you're meant to multiply so I did 3(14)+2 and it gave me 44 :)
Answer:
so it should be 44
Step-by-step explanation:
So the sub for b is 14 so substitute the b to 14
Then 3(14) they are multiplying so multiply them should equal 42
Then add the 2 the answer should be 44

Step-by-step explanation:
Simply multiple the values listed
[tex]3.12 \times {10}^{5} \\ \times 6 \times {10}^{7} [/tex]
You can just multiply the values and keep it in scientific notation. No reason to multiply all if it to find the answer.
[tex]18.72 \times {10}^{12} [/tex]
Now we have to put it into scientific notation, simply move the decimal to the left by 1 and add to the exponenet by 1.

Solve the PROPORTION
3/4 = 1/2y
y=
Answer:
y=1 1/2 (fraction)
or
y=1.5 (decimal)
Step-by-step explanation:
We want to get y alone, so we need to get rid of the 1/2 in front of it. To do that we can multiply each side by 2 since 1/2 + 1/2 = 1.
3/4= 1/2y
multiply each side by 2
To multiply 3/4 by 2 you need to multiply the numerators and then multiply the denominators
2•3=6 & 4 • 1 =4
6/4
simplify
y=1 1/2
(If you need it in decimal form it would be y=1.5)

airplane a traveled 1273 miles in four hours.For airplane b y=621 x/2 represents rate of speed over the same four hours wichair plane traveled at a faster rate and by what factor?round to the nearest hundredth
Answer: Airplane A by a scale factor of 1.02
Step-by-step explanation:
Airplane A: 1273/4=318.25
Airplane B: Rate is the slope of equation, 621/2=310.5
So,
318.25/310.5=1.0249
Airplane 'a' is faster than airplane 'b' by a factor of 1.03 times.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, An airplane 'a' traveled 1273 miles in four hours.
∴ The airplane 'a' traveled (1273/4) = 318.25 miles per hour.
For airplane b y = (621x)/2 + 0b represents the rate of speed over the same four hours
∴ The rate of change per hour for airplane 'b' is (621/2) = 310.5 miles.
So, airplane 'b' is faster than airplane 'a' by a factor of (318/25/310.5) = 1.0257 = 1.03 times.

A fish is swimming at a vibrant rate toward the ocean floor. The equation y=-7x-3 can be used to represent this distinction, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming. Which statement best describes the depth of the fish,given this equation.
A.From a starting position of 7 meters below sea level, the fish is descending 3 meters per second.
B.From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second .
C.From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.
D.From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second.
Answer:
C. From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.
Answer:
C
Step-by-step explanation:
y = -7x - 3 is a linear function that follow y = mx+b. M is the slope or rate. Here m = -7 so the fish descends 7 meters per second. B is the y-intercept or starting position. Here the starting position is -3 so the fish starts 3 feet below sea level.
