18 divided by 4= 4.5
4.5 rounded is 5 so she will need 5 pizzas because you can't buy 4 1/2 pizzas.
10*5= 50 so she will need to spend 50$ on the pizza.

Answer:
piece of cake, she got 350ml of water left
Step-by-step explanation:
lets find out what 10% of 500 is, which is 50
so 20% is 100
we do 10% 3 times, so 50x3=150
500-150=350
it is 350

GE = 26
Step-by-step explanation:
OP = 16 + 9 = 25
PE - OG = 7
Using Pythagorean theorem,
(GE)^2 = (OP)^2 + (PE - OG)^2
=(25)^2 + (7)^2
= 625 + 49
= 674
or
GE = √674 = 25.96 or 26

Solve the system of equations
y=2/3x + 4
2x - 3y=3
A: Infinite Solutions
B: No Solution
C: (3,2)
D: (2,-3)
Answer:
B) no solution
Step-by-step explanation:
this can be solved by substitution method
y= ⅔x + 4. (equation 1)
and 2x-3y= 3. (equation 2)
substitute for y into equation 2
2x-3(2/3x + 4) = 3

Find the margin of error for the given values of c, s, and n.
c=0.95, s=2.5, n = 26
Answer:
0.9609
Step-by-step explanation:
Margin of error is expressed using the formula;
M = z * √s²/n
z is the 95% z score = 1.96
s is the standard deviation = 2.5
n is the sample size = 26
M = 1.96 * √2.5²/26
M = 1.96 * √0.2404
M = 1.96 * 0.49029
M = 0.9609
Hence the margin of error is 0.9609

If my dad is 3x my age today and he was 4x my age 10 years ago, how old will I be in 25 years from now?
Answer:
55
Step-by-step explanation:
We can use the given relations to write an equation that can be solved for my age 25 years from now.
__
Let x represent my age in 25 years. The age relationships can be summarized as ...
in 25 years -- me: xnow -- me: x-25; dad: 3(x-25) = 3x-7510 years ago -- me: x-35; dad: 3x -85We know 10 years ago my dad was 4 times my age, so we have ...
4(x -35) = 3x -85
4x -140 = 3x -85 . . . eliminate parentheses
x = 55 . . . . . . . . . . . add 140-3x
I will be 55 in 25 years from now.

10 years ago, I was 20 and my dad was 80. Now, I'm 30 and my dad is 90. In 25 years, I'll be 55.
In ΔGHI, h = 510 inches, ∠G=25° and ∠H=122°. Find the length of g, to the nearest inch.
9514 1404 393
Answer:
254 in
Step-by-step explanation:
The Law of Sines tells you ...
g/sin(G) = h/sin(H)
g = h(sin(G)/sin(H)) = 510 in(0.42262/0.84805)
g ≈ 254.15
The length of g is about 254 inches.

Answer:
( [tex]-\infty[/tex], 0) and (8, [tex]\infty[/tex])
Step-by-step explanation:
Curve is concave downward when the second derivative is negative.
y' = [tex]\frac{x^{2} }{x^{2} -x+4}[/tex] , by the Fundamental Theorem of Calculus
y'' = [tex]\frac{-x^2+8x}{\left(x^2-x+4\right)^2}[/tex] , which has a denominator that is always positive. The numerator [tex]-x^2+8x[/tex] is negative when x > 0 and when x < 8. So that is when y'' is negative, and consequently when the curve y is concave down.

Which statement best describes g(x) = cube root x + 6 - 8 and the parent function f(x) = cube root X?
Answer:
Here we can not see the options, so I will answer in a general way.
We have the equations:
g(x) = ∛(x + 6) - 8
f(x) = ∛x
First, let's describe the translations.
Vertical translation:
When we have a function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N
Such that if N is positive, the translation is upwards
If N is negative, the translation is downwards.
Horizontal translation:
When we have a function f(x), a horizontal translation of N units is written as:
g(x) = f(x + N)
If N is positive, the translation is to the left
If N is negative, the translation is to the right.
Now that we know that, we can compare the functions:
g(x) = ∛(x + 6) - 8
f(x) = ∛x
So if we start with f(x), we can have a horizontal translation of 6 units to the left:
g(x) = f(x + 6)
And then a vertical translation of 8 units down:
g(x) = f(x + 6) - 8
∛(x + 6) - 8 = f(x + 6) - 8
Then g(x) is the function that you get when you apply a horizontal translation of 6 units to the left followed of a vertical translation of 8 units down to the function f(x)

Saj has made 7 litres of curry sauce.
He wants to put the curry sauce intojas.
Each jar can be completely filled with 375 millilitres of cury sauce.
Saj wants to completely fill as many jars as possible with cury sence.
How many jars can be fill?
Answer:
18 jars can be filled completely.
Step-by-step explanation:
7L=7000ml
1 jar contain 375 ml
375ml can be filled in 1 jar
375ml=1 jar
1 ml = 1/375 jar
7000 ml = 7000× 1/375 jar
7000ml= 18.67 jar
hence 18 jars can be filled completely.
The total number of jars that can be filled with sauce is A = 18 jars
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Saj has made 7 litres of curry sauce = 7000 mL
And , each jar can be completely filled with 375 millilitres of cury sauce
So , the number of jars A = 7000 / 375
On simplifying the equation , we get
A = 18.67 jars
Hence , the number of jars is A = 18 jars
