10 You are planning a party for a group of friends. The cost of
the party will be $30 to rent the room plus $5 per person.
You have a budget of $75. Which inequality gives you the
best estimate of the number of people p that you can invite
to your party?
Answer:
30+5p ≤ 75 (C)
Step-by-step explanation:
Well ”p” is amount of people and every person costs 5 dollars do 5p. 30 dollars for a single room so that s a one time fee, 30+5p
Now the budget can’t be greater than 75 and 75 is the greatest number so we use a less then or equal to sign
5p+30≤75 or (C)
the area of a rectangle whose length is twice its width
Answer:
is there anything else that gose with this question
Step-by-step explanation:
The length of a rectangle is five times its width.
If the perimeter of the rectangle is 60 cm, find its length and width.
length: 7 cm
Х
?
width: 1
cm
Answer:
The length of the rectangle is 25 cm, while the width is 5 cm.
Step-by-step explanation:
Given that the length of a rectangle is five times its width, to find its length and width, knowing that the perimeter of the rectangle is 60 cm, the following calculation must be performed:
(5X x 2) + (X x 2) = 60
10X + 2X = 60
12X = 60
X = 60/12
X = 5
5x5 = 25
Thus, the length of the rectangle is 25 cm, while the width is 5 cm.

[tex]5+x\ge3[/tex] or [tex]6x+1<-29[/tex]
Required
The solution
[tex]5+x\ge3[/tex]
Solve for x
[tex]x \ge 3 - 5[/tex]
[tex]x \ge -2[/tex]
[tex]6x+1<-29[/tex]
Solve for 6x
[tex]6x < -29 - 1[/tex]
[tex]6x < -30[/tex]
Solve for x
[tex]x < -30/6[/tex]
[tex]x < -5[/tex]
Hence, the solution is:
[tex]x \ge -2[/tex] or [tex]x < -5[/tex]

What is the factored form of x9 + 27?
A.
(x3 − 3)(x6 + 3x3 + 9)
B.
(x3 + 3)(x6 − 3x3 + 9)
C.
(x − 3)3(x6 + 3x3 + 9)
D.
(x + 3)3(x6 − 3x3 + 9)
The factored form of the expression is [tex]x^9+27=(x^3 + 3) (x^6 - 3x^3 + 9 )[/tex]
Sum of squares of variablesThe sum of squares of variable a and b is expressed as:
[tex]a^3+b^3=(a + b) (a^2 - ab + b^2 )[/tex]
Given the expression x^9 + 27, this can be written as;
(x³)³ + 3³
where a = x³ and b =3
Substitute
[tex]x^9+27=(x^3 + 3) (x^6 - 3x^3 + 9 )[/tex]

since the angle 1 and 2 both measures 90⁰
Answer: Choice 2 Adjacent and Choice 4 Supplementary
Step-by-step explanation:
Here, we are given four choices, and I will be defining each of them.
Vertical angles: two angles that are opposite to each other which was formed by two intersecting lines.Adjacent angles: two angles that share one common vertex and "arm"Complementary angles: two angles that add up to 90°Supplementary angles: two angles that add up to 180°-----------------------------------------------------------------------------------------------
We can see from the figure given
Both angles are 90°, so ∠1+∠2=90+90=180°
Which is supplementary.
We can see from the figure given
Both angles share a common arm and vertex
Which is adjacent

Mr x will retire at the age of 60 years he wishes to have an amount of 200000 in his account at the time of retirement currently he is 40years and has an amount of 25000 how much interest rate bank should offer
Answer:
Rate of interest = 10.95%
Step-by-step explanation:
Given:
Amount deposit in bank = 25,000
Number of year = 60 year - 40 year = 20 year
Future value = 200,000
Find:
Rate of interest
Computation:
A = P[1+r]ⁿ
Future value = Amount deposit in bank[1+Rate of interest]ⁿ
200,000 = 25,000[1+r]²⁰
8 = [1+r]²⁰
1.1095 = 1 + Rate of interest
Rate of interest = 0.1095
Rate of interest = 10.95%
