Answer:
The length of the rectangle is 28 inches.
Step-by-step explanation:
We have that the width (W) of a rectangle is half of the length (L) of the rectangle:
[tex] W = \frac{1}{2}L [/tex] (1)
Also, the perimeter is 84 inches:
[tex] P = 2W + 2L = 84 in [/tex] (2)
By entering equation (1) into equation (2) we have:
[tex]2(\frac{1}{2}L) + 2L = 84 in[/tex]
[tex] L = \frac{84}{3} = 28 in [/tex]
Therefore, the length of the rectangle is 28 inches.
I hope it helps you!

Roy has $30 in a savings account. The interest rate is 10% per year and is not
compounded. How much will he have in 4 years?
Answer:
$43.92
Step-by-step explanation:
1st year:
30 x 10% = 3
30 + 3 = 33
2nd year:
33 x 10% = 3.3
33 + 3.3 = 36.3
3rd year:
36.3 x 10% = 3.63
36.3 + 3.63 = 39.93
4th year:
39.93 x 10% = 3.99
39.93 + 3.99 = 43.92
write the slope-intercept form of the equation of a line with a slope of -5/8 that passes through the point (-14, 6)
Answer:
y=-5/8x-11/4
Step-by-step explanation:
y-y1=m(x-x1)
y-6=-5/8(x-(-14))
y-6=-5/8(x+14)
y=-5/8x-70/8+6
y=-5/8x-11/4

A radioactive substance has a half-life of one month, which means that at the end of each month, the level of radioactivity is half the level that it was at the beginning of the month The substance was discovered in the soil
near a high school football field. The table shows the relationship between the radioactivity level found in the soil, r(t)and the number of months since discovery, 2.

Which statement correctly interprets the initial value?
The level of radioactivity in the soil is decreasing by a factor of 1/2 each month
find the slope of the line that goes through (-4,2) and (3,-5)
Answer:
-1
Step-by-step explanation:
m = -7 / 7 = -1 / 1 = -1
Answer:
-1
Step-by-step explanation:
To find the slope given two points, use the formula: [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]. In this case, the formula would be: [tex]\frac{-5-2}{3-(-4)}[/tex]. Solve the top first: -7. Solve the bottom next: 7. So your answer is: [tex]\frac{-7}{7}[/tex] or -1.

What is the value of the smaller zero of the function defined by 2x2 + 9x + 7?
Answer:
We can factor the quadratic function into (2x + 7)(x + 1) and this way, the terms sum to 2x^2 + 9x + 7. Looking at the 2 factors 2x+7 and x+1, the way to find the zeros is to set both of these expressions equal to 0. Therefore we have: 2x+7=0

In a bag of sweets, 6 are orange and 9 are lime. Jodi chooses a sweet at random, eats it an
then chooses a second sweet at random.
What is the probability that both sweets are the same flavour?
(3 Points)
Answer:[tex]\frac{17}{35}[/tex]
Step-by-step explanation:
Given
The bag contains 6 orange and 9 lime sweets
For both sweets of the same flavor, Jodi must either choose orange or lime
No. of ways it can be done is [tex]^6C_1\times^5C_1+^9C_1\times^8C_1[/tex]
The total no of ways of selecting two sweets out of 15 is [tex]^{15}C_1\times^{14}C_1[/tex]
The probability that both sweets are the same flavor
[tex]P=\dfrac{^6C_1\times^5C_1+^9C_1\times^8C_1}{^{15}C_1\times^{14}C_1}=\frac{102}{210}=\frac{51}{105}=\frac{17}{35}[/tex]
