Sean has 9 liters of juice. He pours equal amounts of the juice into 4 pitchers. There is 0.5 of a liter of juice left. How many liters of juice are in each pitcher? Sean has 9 liters of juice. He pours equal amounts of the juice into 4 pitchers. There is 0.5 of a liter of juice left. How many liters of juice are in each pitcher?
Answer:
2.125 liters of juice
Step-by-step explanation:
Total liters of juice = 9
Total liters left = 0.5
Total liters used = Total liters of juice - Total liters left
= 9 - 0.5
= 8.5
Total liters used = 8.5 liters
He pours equal amounts of the juice into 4 pitcher
Liters per pitcher = Total liters used / number of pitchers
= 8.5 / 4
= 2.125 liters
Liters per pitcher = 2.125 liters
Each pitcher has 2.125 liters of juice
BE||CD. Find the value of x and AC.
Answer:
x = 4.8
AC = 16.8
Step-by-step explanation:
From the picture attached,
In ΔABE and ΔACD
BE║CD, and the AC and AD are the transversal lines.
∠ABE ≅ ∠ACD [Corresponding angles]
∠AEB ≅ ∠ADC [Corresponding angles]
ΔABE ~ ΔACD [By AA property of similarity of two triangles]
And by the property of similar triangles, corresponding sides of the similar triangles are always proportional.
[tex]\frac{\text{AC}}{\text{AB}}=\frac{\text{AD}}{\text{AE}}[/tex]
[tex]\frac{x+12}{12}=\frac{10+4}{10}[/tex]
[tex]\frac{x+12}{12}=\frac{14}{10}[/tex]
10(x + 12) = 12 × 14
10x + 120 = 168
10x = 168 - 120
x = 4.8
AC = x + 4.8
= 12 + 4.8
= 16.8

y=-1/2x(x-8)
Show steps to put in vertex form
Answer:
y = [tex]\frac{-1}{2}x^{2}[/tex] + 4x + 0
Step-by-step explanation:
y = -1/2x(x-8) (distributive property of equality)
y = -1/2x^2 + 4x + 0
Vertex form : y = ax2 + bx + c
There is no C so you can also represent that by putting a zero so,
y = -1/2x^2 +4x + 0,
Which is the same as,
y = [tex]\frac{-1}{2}x^{2}[/tex] + 4x + 0

less confusing lol.

When multiplying a whole number by a positive fraction smaller than 1, the answer is always smaller than the original number.
Examples:
5 · [tex]\frac{1}{2}[/tex] = 2 [tex]\frac{1}{2}[/tex] or 2.5
6 · [tex]\frac{3}{4}[/tex] = 4 [tex]\frac{1}{2}[/tex] or 4.5
14 · [tex]\frac{1}{3}[/tex] = 4 [tex]\frac{2}{3}[/tex]
When dividing a whole number by a positive fraction smaller than 1, the answer is always bigger than the original number.
Examples:
5 ÷ [tex]\frac{1}{2}[/tex] = 10
6 ÷ [tex]\frac{3}{4}[/tex] = 8
14 ÷ [tex]\frac{1}{3}[/tex] = 42

3(x+6)+6x+9=7x+8 Solve for x.*
A -19/2
B 19/2
C 2/19
D -2/19
Answer:
a) -19/2
Step-by-step explanation:
3(x+6)+6x+9=7x+8
3x + 18 + 6x + 9 = 7x + 8
3x + 6x - 7x = 8 - 18 - 9
2x = -19
2x/2 = -19/2
Therefore, x = -19/2

Divide using synthetic division, and write a summary statement in fraction form
2x^3+3x^2+4x-10/x + 1
Using synthetic division, a summary statement in fraction form of the polynomial division is; 2x² + x + 3 - (13/(x + 1))
How to use Synthetic Division?
We are given the polynomial fraction as;
(2x³ + 3x² + 4x - 10)/(x + 1)
This means that we want to divide the polynomial (2x³ + 3x² + 4x - 10) by (x + 1) using synthetic division.
For the divisor, we have x + 1, and that means x + 1 = 0, x = -1
So, we'll be using -1 for the synthetic division and we have;
-1 | 2 3 4 -10
× -2 -1 -3
-------------------------
2 1 3 -13
Now we will form the expression in the form of fraction again
2x² + 1.(x) + 3 - 13/(x + 1)

Answer:
The answer is 25z^2+2-15z
Step-by-step explanation:
The form one will often see polynomials in is called standard form. It is when the terms are ordered in highest degree to lowest degree. For example, when given the polynomial x4+2x3+x+11, it is in standard form because 4 is the highest power, then 3 and 1.
