Answer: | t- 98.6 | ≤ 3
Temperatures less than 95.6 and higher than 101.6 will be considered unhealthy.
Step-by-step explanation:
Hi, to answer this question we have to write an inequality
.
| t- 98.6 | ≤ 3
Where t is the body temperature.
The absolute value inequality has 2 solutions:
1st solution
t-98.6≤ 3
t ≤ 3+98.6
t≤ 101.6
2nd solution
-(t-98.6) ≤ 3
-t+98.6 ≤ 3
98.6-3 ≤ t
95.6≤ t
Both:
95.6≤ t ≤ 101.6
Temperatures less than 95.6 and higher than 101.6 will be considered unhealthy.

Zac invests $3500 at 8% p.a. simple interest for a period of time, to produce $210 interest. For how long did he invest the money?
Please help me in the steps to finding the answer and also the solution. Thx
Answer:
9 months
Step-by-step explanation:
simple interest ( I) is calculated as
I = [tex]\frac{PRT}{100}[/tex]
P is the principal, R the rate of interest and T the time in years
Here I = 210, P = 3500 and R = 8, thus
210 = [tex]\frac{3500(8)T}{100}[/tex] = 35 × 8T = 280T ( divide both sides by 280 )
0.75 = T
Thus T = 0.75 years = 9 months
The money was invested for 9 months
Answer:
9 months
Step-by-step explanation:
investment= 3500
interest rate= 8% PA simple
time= x years
Interest= $210
---------------
3500*0.08*x=210280x=210x=210/280=3/4 year3/4 year= 3/4*12 month= 9 months

Answer:
the expression is equivalent to x^2/3
Step-by-step explanation:
[x^4/3 x^2/3]^1/3
=[x^4/3+(2/3)]^1/3
by using laws of exponent
a^m a^n=a^m+n
=[x^4/3+2/3]^1/3

2) An employee makes a job change. Her original salary was $65,000, and her salary at her new job is $54,000. What percent decrease was her salary change?
Please show your work for full credit.
Answer:
An employee makes a job change.
Her original salary was S1 = $65,000.
Her salary at her new job is S2 = $54,000.
=> The percentage of change in her salary:
C = (|S2 - S1|/S1) x 100 = (|54000 - 65000|/65000) x 100 = 16.9%
Hope this helps!
:)
Answer:
Step-by-step explanation:
Decreased amount =65,000 - 54,000 = $ 11000
[tex]Percentage=\frac{11000}{65000}*100\\\\=\frac{1100}{65}\\\\[/tex]
=16.92%

Marissa is painting her rectangular patio, with the exception of a bench that does not need to be painted: rectangle with a length of x plus 15 and width of x plus 10 with a rectangle in the bottom right corner labeled bench that has a length of 5 and width of 1
a=(x+20)(x+11)
a=(x+15)(x+10) + 5
a=(x+15)(x+10) - 5
a=(x+9)(x+10)
Answer:
C
Step-by-step explanation:
A patio=(x+15)*(x+10)
A bench=5*1=5
A painted=A patio-A bench
A painted=(x+15)*(x+10)-5
thus, the answer is C
The painted area is [tex]a=(x+15)(x+10)-5[/tex]. So, option C is correct.
Important information:
Length of rectangular patio is (x+15).Width of rectangular patio is (x+10).Length of bench is 5.Width of bench is 1.Area of rectangle:Area of a rectangle is:
[tex]A=Length \times Width[/tex]
Area of rectangular patio is:
[tex]A_1=(x+15)(x+10)[/tex]
Area of bench is:
[tex]A_2=5\times 1[/tex]
[tex]A_2=5[/tex]
The painting area is:
[tex]a=A_1-A_2[/tex]
[tex]a=(x+15)(x+10)-5[/tex]
Therefore, the correct option is C.

Which graph represents the solution set for the quadratic inequality x^2+2x+1>0?
Answer:
x > -1 (Answer D)
Step-by-step explanation:
Note that x^2 + 2x + 1 > 0 is equivalent to (x + 1)^2 > 0. This has two solutions: {-1, -1} (two real, equal roots). The solution set includes all real numbers such that x > -1 (Answer D)
If we are given x such that 25^x-9^y=18 and 5^x-3^y=3, compute 5^x+3^y.
25 = 5*5 and 9 = 3*3, which we can exploit to write
[tex]25^x-9^y=(5^2)^x-(3^2)^y=5^{2x}-3^{2y}=(5^x)^2-(3^y)^2[/tex]
so that this expression is actually a difference of squares. We can factorize this to get
[tex](5^x-3^y)(5^x+3^y)=18[/tex]
and given that [tex]5^x-3^y=3[/tex], we divide both sides by this to get
[tex]5^x+3^y=\dfrac{18}3=\boxed{6}[/tex]

2. A breakfast cereal is made of oats, nuts, and raisins. The advertisements boast that 25% of the cereal in each box is almonds. If each box contains 12 cups of cereal, how many cups of almonds are in each box?
3. A breakfast cereal is made of oats, nuts, and raisins. Each box contains 12 cups of cereal, and 4 cups are oats. What percentage of each box is oats?
Answer:
Step-by-step explanation:
1) The advertisements boast that 25% of the cereal in each box is almonds. It means that the percentage of the other cereals in the box is 100 - 25= 75%
Therefore, the portion of each box that is not almonds is 75/100 = 0.75
2) The advertisements boast that 25% of the cereal in each box is almonds. If each box contains 12 cups of cereal, then the number of cups of almonds in each box is
25/100 × 12 = 3 cups
3) if each box contains 12 cups of cereal, and 4 cups are oats, then the percentage of each box that is oats is
4/12 × 100 = 33.33%

Write the linear equation in the slope-intercept form when m=1 and b=-12
Answer:
y = x - 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Here m = 1 and b = - 12 , thus
