School yearbooks cost $23. Fifty-six yearbooks have already been sold. How many more yearbooks x must be sold to earn at least $2001? Write your answer as an inequality.
Answer:
x [tex]\geq[/tex] 31
Step-by-step explanation:
Total number of the yearbooks is 56 + x
Total money earned is 23*(56 + x)
so 23*(56 + x) [tex]\geq[/tex] 2001
56 + x [tex]\geq[/tex] 2001/23 = 87
x [tex]\geq[/tex] 87 - 56 = 31
Answer: x [tex]\geq[/tex] 31

Really simple algebra equation!
Giving 50points!
Answer:
a=10
Step-by-step explanation:
use a^2+b^2=c^2
(a+2)^2+(a-5)^2=(a+3)^2
a^2+4a+4+a^2-10a+25=a^2+6a+9
2a^2-6a+29=a^2+6a+9
a^2-12a=-20
a^2-12a+20=0
quadratic formula→(12+/-8)/2
a=10 or 2
2 is not an option because 2-5=-3 which isn't possible in this case.
so a=10
Apply Pythagorean theorem
(a-5)²+(a+2)²=(a+3)²a²-10a+25+a²+4a+4=a²+6a+9a²-6a+29=6a+9a²-12a+20=0a²-10a-2a+20=0a(a-10)-2(a-10)=0(a-2)(a-10)=0a=2,10There is a side a-5 so 2 is not a answer
a=10

Hello i need help with my assignment thank you in advance and i know you deserve the point
Answer:
1) a = 51, 2) b = 57, 3) c = 53, 4) e = 49 d = 131, 5) f = 33, 6) g = 79, 7) h = 42 j = 47, 8) m = 59 k = 17 i = 104, 9) n = 55
Step-by-step explanation:
1.
You see that angle HJK has a total degree angle of 115, half of the angle is already stated to be 64 degrees, so you would just have to find the remainder. 115 - 64 = 51
2.
The question follows the same format, when you see the square in the corner it generally means that it is a 90-degree angle. So following the same steps as last time angle b would be 90 - 33 = 57
3.
Whenever there is a flat line given the angle is equal to 180 degrees, think of it as putting two 90 degree angles back to back. So if they equal 180 angle c would equal 180 - 127 = 53
4
This question is just a little different when you see crossing perpendicular lines angles across from each other equal the same amount, so angle d would be 131. Finding angle e is not hard either, back to question 3 for when it was just a straight line the same logic can be applied here. e would equal 180 - 131 = 49
given the information in the picture which trigonomic identity can be used to solve for the height of the blue ladder that is leaning against the building
Answer:

solve for x,y, and 15
Answer:
27
Step-by-step explanation:
x + y = 15 (gallons) (1)
0.25*x + 0.10 * y = 0.15 * 15 (2)
Multiply 100 on (2):
25x + 10y = 15
Divede by 5
5x + 2y = 3 (3)
From (1) y = 15 - x
so 5x + 10*(15 - x) = 15
5x + 150 - 10x = 15
-5x = 15 - 150 = -135
x = 135/5 = 27 (gallons)

What is the value of the expression 9 + (1/2) with a power of 4 • 48? A. 12 B. 15 C. 17 D. 18
Answer:
Option A
Step-by-step explanation:
Given the following question:
[tex]9+(\frac{1}{2})^4\times48[/tex]
In order to find this, answer we use order of operations and solve.
[tex]9+(\frac{1}{2})^4\times48[/tex]
[tex]\frac{1}{2} ^4=\frac{1}{2} \times\frac{1}{2} \times\frac{1}{2} \times\frac{1}{2} =\frac{1}{16}[/tex]
[tex]9+\frac{1}{16} \times48[/tex]
[tex]\frac{1}{16} \times48=\frac{1}{16}\times\frac{48}{1} =\frac{3}{1} =3[/tex]
[tex]9+3[/tex]
[tex]9+3=12[/tex]
[tex]=12[/tex]
Which means your answer is option A or "12."

Solve for x.
−5x−8>22
Enter your answer in the boxes to correctly state the solution.
Answer:
x < -6
Step-by-step explanation:
-5x - 8 > 22
Add 8 to both sides: -5x > 30
Divide both sides by 5: -x > 6
Divide both sides by -1 (reverse sign): x < -6
Answer:
x < -6
Step-by-step explanation:
First we want to move all terms not containing x to the right side
-5x > 22 + 8
-5x > 30
Then we want to divide
-5x/5 < 30/-5
30/-5
x < - 6
To visit the manila Zoo, 11 adults and 5 Children have to pay 270 whereas 14 adults and 9 children have to pay 370? Find the total amount a family of 2 adults and 3 children has to pay to visit the zoo.
Step-by-step explanation:
let adults be x and childrens be y
a/q
11x + 5y = 270
14x + 9y = 370
→ x = -5/11y + 270/11 ; 14x + 9y = 370
→ 14(-5/11y + 270/11) + 9y = 370
→ y = 10
→ x = -5/11 × 10 + 270/11
→ x = -50/11 + 270/11
→ x = 20
therefore, we got
x = 20, y = 10
each adult have to pay 20 and each children have to pay 10
so,
2 × 20 = 40
3 × 10 = 30
40 + 30 = 70
for a family of 2 adults and 3 children they have to pay 70.

If two cards are randomly drawn from a deck of ordinary playing cards, one at a time, with replacement, what is the probability of obtaining no aces
Answer:

Step-by-step explanation:
There are 52 cards, 4 are aces, so the probability of not getting ace is 48/52, so we square it, or multiply it by itself to get 144/169

Find a polynomial f (x) of degree 4 that has the following zeros.
0, -8 (multiplicity 2), 7
Leave your answer in factored form.
Answer:
[tex]f(x)=x(x-7)(x+8)^2[/tex]
Step-by-step explanation:
The zeros of the polynomial are all the values of [tex]x[/tex] for which the function [tex]f(x)=0[/tex]
Therefore,
[tex]x = 0[/tex]
[tex]x = -8 \implies x + 8 = 0[/tex] (twice)
[tex]x = 7 \implies x -7 = 0[/tex]
Write the polynomial as a product of its factors:
[tex]f(x)=x(x-7)(x+8)^2[/tex]

Answer:
364.46
Step-by-step explanation:
First we need the height of the cone
so we divide the cone to two equal parts that means the adjacent 5 inches will be divided into two to give 2.5
then we use get a triangle from the cone and that's how we find our height using pythagoras theorem
hypotenuse Square = opposite Square + adjacent Square
7^2 = x^2 + 2.5^2
therefore our height is 6.53
now to get the surface area of the cone we use the formula
pi×r( r + Square root of r^2 + h^2

13/x = 2/2-x
enter the value of x that makes the equation true
Answer:
26/15
Step-by-step explanation:
13/x= 2/2-x
the next step from here is to cross multiply and when we do that it's looks like this
13(2-x)=2*x
then we multiply
26-13x=2x
we then collect like terms
26=15x
therefore x= 26/15
we can leave our answer in this format or convert it to mixed fraction or decimal but its best to leave it in this format
Two or more expressions with an Equal sign is called as Equation. Value of x is 26/15 for equation 13/x=2/(2-x)
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is
13/x=2/(2-x)
Apply cross multiplication
13(2-x)=2x
Apply Distributive property on LHS side
13(2)-13x=2x
26-13x=2x
Add 13x on both sides
26-13x+13x=2x+13x
26=15x
x=26/15
Hence value of x is 26/15 for equation 13/x=2/(2-x)
