Answer:
Step-by-step explanation:
4) A photograph costs $20, so the cost of x photographs is 20x.
Similarly, the cost of y prints is $25.
So the total cost is 20x+25y, and this has to be less than or equal to 400, so C.
5) just plug each pair in.
For example for the first option, x=5 and y=10, and since 20(5)+25(10)=100+250. which is less than or equal to 400, it works.

3-1 4/6?
Answer:
[tex]\frac{4}{3}[/tex] or [tex]1\frac{1}{3}[/tex] (don't worry, they are the same thing)
Step-by-step explanation:
[tex]3-1\frac{4}{6}[/tex]
[tex]3-\frac{10}{6}[/tex]
[tex]\frac{18}{6} -\frac{10}{6}[/tex] (18/6 is equivalent to 3, and 10/6 is equivalent to 1 4/6)

Can someone please help me Factor 100x2−20xy+y2
Answer:
(10x-y)^2
Step-by-step explanation:
1
Rewrite it in the form {a}^{2}-2ab+{b}^{2}a2−2ab+b2, where a=10xa=10x and b=yb=y.
{(10x)}^{2}-2(10x)(y)+{y}^{2}(10x)2−2(10x)(y)+y2
2
Use Square of Difference: {(a-b)}^{2}={a}^{2}-2ab+{b}^{2}(a−b)2=a2−2ab+b2.

Step-1: Find the missing side length using Pythagoras theorem:
115² = 69² + x²=> 13225 = 4761 + x²=> 13225 - 4761 = x²=> 8464 = x²=> x = √8464 = 92Step-2: Find the area of the rectangle:
Area of rectangle = LB=> 69 x (92 + 100)=> 69 x 192=> 13248 units²Apply Pythagorean theorem
[tex]\\ \rm\bull\rightarrowtail b^2=115^2-69^2[/tex]
[tex]\\ \rm\bull\rightarrowtail b^2=13225-4761[/tex]
[tex]\\ \rm\bull\rightarrowtail b^2=8464[/tex]
[tex]\\ \rm\bull\rightarrowtail b=92[/tex]
Now length=192Breadth=69Area=Length×Breadth

A. X=-4
B. x= -1

Step-by-step explanation:
[tex]\tt 8=2^{(x+4)}[/tex]
(First, convert both sides to the same base):-
[tex]\tt 2^3=2^{x+4}[/tex]
(Now, cancel the base of 2 on both sides):-

Answer:
1.9166666 . . . or 1 and 23/24
Step-by-step explanation:
1 foot is 12 inches, and 23 divided by 12 is 1 and 23/24
23/12 = 1.9166666 . . . . or 1 and 23/24
In basketball, Shaquille makes 40% of his free throw attempts. He goes to the free throw line to shoot one-and-one (if he makes the first shot, he gets to shoot one more). He scores 1 point per free throw. What is the expected value of the number of points he will score? 0. 064 0. 24 0. 56 0. 80.
Shaqquille's expected value is 0.56 points.
Step-by-step explanation:
Situations:
1) he makes 1st shot + he makes 2nd shot
P(A) = 0.4 · 0.4 = 0.16 ( 16 % )
2) he makes 1 st shot + he misses 2nd shot
P(B) = 0.4 · 0.6 = 0.24 ( 24 % )
3) he misses 1st shot and he has no more attempts
P (C) = 0.6 ( 60 %)
0.16 · 2 + 0.24 · 1 + 0.6 · 0 = 0.32 + 0.34 = 0.56
The expected value is 0.56 points.

The school that Lisa goes to is selling tickets to a fall musical. On the first day of ticket sales the school sold 4 adult tickets and 6 child tickets for a total of $130. The school took in $280 on the second day by selling 10 adult tickets and 12 child tickets. Find the price of an adult ticket and the price of a child ticket.
Answer:
adult $10 Children $15
Step-by-step explanation:
4A + 6C = 130
10A + 12C = 280
Multiply the first by -2 to eliminate C
-8A -12C = - 260
10A +12C = 280
ADD BOTH
2A = 20
A=10 ($10 per adult)
40+6C = 130
6C = 90
C=15 (15 per child)

The slope of an equation is how the line will move on the graph. Since we already have the fixed price of 39 dollars, that will be the y-intercept of the graph, or where we start with our line. Since each year the fee is 1.8, the line changes by 1.8 in y for every x.

Answer 23:
Lina would pay $19,600 in the four years.
Step-by-step explanation:
To find the answer of this problem, you'll first have to find how much she payed in interest.
To find the interest:
[tex]\frac{14,000}{x}[/tex]=[tex]\frac{4}{100}[/tex] (Cross Multiply)
or if you like the equation version: x=.04($14,000) = $5,600
Great! Now you've gotten the interest she has to pay. Now that you have that, add the interest and the total she borrowed from the bank.
$14,000 + $5,600 = $19,600
There you go, and that is you find the answer to Problem 23.

Solve for x. Round to the nearest tenth, if necessary.
Answer:
x=229.8
Step-by-step explanation:
We can use a trigonometric ratio to solve for x.
If we use 72 as our reference angle, we can solve for x using cosine: [tex]cos (72)=\frac{71}{x} \\\\x*cos(72)=71\\\\x=\frac{71}{cos(72)}\\ \\x=229.7608=229.8[/tex]

What is the area of the shape?
units
Answer:
56 units squared
Step-by-step explanation:
First, we want to find the area of the triangle taken out of the top. We can tell that the rectangle area that it's in is 28 units because it's 7 across and 10-6=4. To find the area of a triangle you just divide that 28 by 2 to get 14. 70-14 is 56. Ik I'm not the best at explaining things so if you have any questions feel free to ask bc I explained this weirdly.

) A comet travels at an average speed of 264,000 km/h. It takes 8 days for the comet to reach Earth. Find the distance, in km, the comet travelled.
Answer:
Distance the comet travelled: x
1 day = 24 hours
24 * 8 = 192 hours
x = 264,000 * 192 = 50,688,000 (because speed = distance/time, so distance = speed * time)
