Answer:
The irrational numbers from the given options are :-
[tex]17\pi[/tex][tex]0.21475467.....[/tex][tex]-\frac{4}{5} + \sqrt{\frac{6}{9} }[/tex]Step-by-step explanation:
Analyse each option carefully.
1) [tex]13 + \sqrt{25}[/tex] is a rational number because :-
[tex]\sqrt{25} = 5[/tex][tex]13 + \sqrt{25} = 13 + 5 = 18[/tex] , which is a rational number.2) [tex]17\pi[/tex] is irrational because :-
Value of π has a non-terminating & non-recurring decimal value. So it is irrational number.If π is irrational , then 17π is also irrational because product of any number and an irrational number is always irrational.3) [tex]0.21475467....[/tex] is irrational because :-
It is a non-terminating & non-recurring decimal.Any non terminating & non-recurring decimal is an irrational number.4) [tex]\sqrt{\frac{9}{16} }[/tex] is rational because :-
[tex]\sqrt{\frac{9}{16} } = \frac{\sqrt{9} }{\sqrt{16} } = \frac{3}{4}[/tex].[tex]\frac{3}{4}[/tex] is a rational number.5) [tex]-\frac{4}{5} + \sqrt{\frac{6}{9} }[/tex] is irrational because :-
[tex]\sqrt{\frac{6}{9} } = \frac{\sqrt{6} }{\sqrt{9} } = \frac{\sqrt{6} }{3}[/tex] , which is irrational.If [tex]\frac{\sqrt{6} }{3}[/tex] is irrational , then [tex]-\frac{4}{5} + \sqrt{\frac{6}{9} }[/tex] is also irrational because sum of any number and an irrational number is always an irrational number.1. Calculate exactly;

What is cos45degrees? work shown please
Answer: [tex]\dfrac{1}{\sqrt{2}}[/tex]
Step-by-step explanation:
The value of [tex]\cos 45^{\circ}[/tex] is the fixed value i.e. [tex]\frac{1}{\sqrt{2}}[/tex]
The values of cosine changes from a maximum at [tex]0^{\circ}[/tex] to a minimum at [tex]180^{\circ}[/tex]
for example, [tex]\cos 0^{\circ}=1, \quad \cos 90^{\circ}=0,\quad \cos 180^{\circ}=-1[/tex]
Solve the equation for x
Answer:
B. x = -4
Step-by-step explanation:
- 7x - 35 = -7
add 35 to both sides
-7x = 28
Divde both sides by -7
x = -4
Answer: X = -4
Step-by-step explanation:
-7x - 35 = -7
-7x = -7 + 35
-7x = 28
x = -4

3x+(5)(2)+(5)(x)=4x+−7(Distribute)
3x+10+5x=4x+−7
(3x+5x)+(10)=4x−7(Combine Like Terms)
8x+10=4x−7
8x+10=4x−7
Step 2: Subtract 4x from both sides.
8x+10−4x=4x−7−4x
4x+10=−7
Step 3: Subtract 10 from both sides.
4x+10−10=−7−10
4x=−17
Step 4: Divide both sides by 4.

If you wash your car every 15 days & I wash mine every 20 days, in how many days will we be washing them on the same day?
Answer: 60 days
Step-by-step explanation:
To get the number of days that both of them will be washing the cars on thesame day, we have to find the lowest common multiple of 15 and 20. This will be:
Multiple of 15 = 15, 30, 45, 60, 75, 90
Multiples of 20 = 20, 40, 60, 80, 100
Lowest common multiple = 60
Therefore, they'll be Washing the car on thesame day on the 60th day.

Boyle's law is :

what happens to the pressure of a container if the volume is doubled and the temperature is kept the same?
- impossible to determine with the info provided
- the pressure will increase
- the pressure will decrease
- the pressure will stay the same
Answer:
- the pressure will decrease
(volume is doubled ,the pressure reduced by half).
Step-by-step explanation:
P_1 V_1=P_2 V_2
This equation shows that, as volume increases, the pressure of the gas decreases in proportion.
Similarly, as volume decreases, the pressure of the gas increases.

Step-by-step explanation:
A school pays $1,825 for 150 shirts. This includes the $25 flat-rate shipping cost.
a. What equation models the total cost as a function of the number of T-shirts
ordered?
b. What does each variable represent?
c. What are the initial value and rate of change of the function? What does each
one represent?
Answer:
a)
We know that the total cost for the 150 shirts (plus a flat-rate of $25) is $1,825.
First, let's find how much costs each shirt.
First, the total cost of the shirts alone (neglecting the flat-rate) is:
$1,825 - $25 = $1,800
Then each shirt costs equal to the quotient of the cost and the number of shirts:
$1,800/150 = $12
Each shirt costs $12.
Then if you order T shirts, the total cost will be the flat-rate of $25 plus T times $12. The equation is:
C(T) = $25 + T*$12
b) C represents the cost
T represents the number of shirts ordered.
c) The initial value is the constant value, in this case, is $25
The rate of change is the coefficient that multiplies the independent variable (T), in the equation the rate of change is $12.

The club will base its decision about whether to increase the budget for the indoor rock climbing facility on
the analysis of its usage. The decision to increase the budget will depend on whether members are using
the indoor facility at least two times a week. Use the best measure of center for both of the original data
sets to determine whether the club should increase the budget. Assume there are four weeks in a month.
If you think the data is inconclusive, explain why.
Answer:
Yes, they should increase the budget, because both 8 (Manuel) and 9 (Gretchen) are at least 8. 8 times per month is equivalent to 2 times per week.
