Answer: 1:30
Step-by-step explanation: It took two hours to fill 1,800 gallons. 1,800 x 2 = 3,600.
It would take another two hours for the pond to be full. So, 11:30 time skip to two hours is 1:30.
What is the domain and range of this function?
f(x) = logs(x - 2) + 1
OA.
domain: x > -2; range: all positive real numbers
OB.
domain: x> 2; range: all positive real numbers
OC. domain: x>-2; range: all real numbers
OD. domain: x> 2; range: all real numbers
Answer:
Domain = x > 2 , Range = {R}
Step-by-step explanation:
The given function to us is ,
[tex]\implies f(x) = log_{10} ( x - 2 ) + 1 [/tex]
Since logarithm are defined only for positive numbers therefore ,
=> (x - 2) > 0
=> x > 2
Therefore the domain of the function is x > 2 and it can have all positive real numbers .
There are three small rounds of cheddar cheese in Grace’s refrigerator. She wants to bring a small wedge of cheese in her lunch every day for the next 12 days of school. If she wants to eat the same amount of cheese every day, how much cheese should she bring for lunch each day?
Solution:
Number Model:
Answer:
The one-fourth of one round of cheddar cheese
Step-by-step explanation:
Because if we cut every round in 4 equal pieces, 4x3=12, we will have 12 equal pieces of cheddar cheese.

Find the area of the composite shape.
1,323 cm squared
1,209 cm squared
955.5 cm squared
1,029 cm squared
Answer:
4. A = 1029 cm²Steps:
A = (35×21)+(21+2×3.5)×21/2
A = 735 + (21+7)×21/2
A = 735 + 28×21/2
A = 735 + 588/2
A = 735 + 294
A = 1029 cm²Solve the simultaneous equations

HELP
Answer:
d. The relative frequency of the people that chose drama is 0.1[tex]\overline 6[/tex]
e. The relative frequency of the people that chose action is 0.2
Step-by-step explanation:
The result of the survey is expressed as follows;
C, C, R, R, D, R, H, H, C, A, A, R, A, A, A, R, R, H, H, H, C, H, A, R, D, D, D, D, H, R
Sorting the data, with Microsoft Excel, we get;
A, A, A, A, A, A, C, C, C, C, D, D, D, D, D, H, H, H, H, H, H, H, R, R, R, R, R, R, R, R
From the pivot table created with Microsoft Excel, we have
The frequency of As = 6
The frequency of Cs = 4
The frequency of Ds = 5
The frequency of Hs = 7
The frequency of Rs = 8
The sum of all frequency = 6 + 4 + 5 + 7 + 8 = 30
d. The relative frequency of the people that chose drama is given as follows;
[tex]Relative \, frequency = \dfrac{Frequency \ of \ observation}{Sum \ of \ all \ frequencies}[/tex]
The frequency of the people that chose drama = 5
The sum of all frequency = 30
[tex]Relative \, frequency \ of \ the \ people \ that \ chose \ drama = \dfrac{5}{30} = \dfrac{1}{6} = 0.1\overline 6[/tex]
The relative frequency of the people that chose drama = 0.1[tex]\overline 6[/tex]
e. The relative frequency of the people that chose action, RF action, is given as follows;
[tex]RF \ action = \dfrac{Frequency \ of \ the \ people \ that \ chose \ action}{Sum \ of \ all \ frequencies} = \dfrac{6}{30} = \dfrac{1}{5} = 0.2[/tex]
The relative frequency of the people that chose action, RF action = 0.2.
Please Help! Solve the equation for x.
1/3x-8= -12
A. x= -12
B. x= -6
C. x= 4
D x= 6
Answer:
A
Step-by-step explanation:
Given
[tex]\frac{1}{3}[/tex] x - 8 = - 12 ( multiply through by 3 to clear the fraction )
x - 24 = - 36 ( add 24 to both sides )
x = - 12 → A

help me plz 10 points
Answer:
580 cm
Step-by-step explanation:
To find the surface area you just need to find the area of every side of the box and add them together.
SO- the equation for this would be
SA (Surface Area) = 2(20 x 10) + 2(20 x 3) + 2(10 x 3)
SA = 2(200) + 2(60) + 2(30)
SA = 400 + 120 + 60
SA = 520 + 60
SA = 580

2*2=4
4*2=8
8*2= 16 so blue is correct
8*8=64 so cyan is not correct
2^8=256 so yellow is not correct
4*4=16 so red is correct
2^4 is the same as 2*2*2*2 which equals 16 so purple is also correct

Please help me with this and find x!! Thank you, only if you know!
Answer:
x = 9.8
Step-by-step explanation:
to find x, use pythagorean theorem
[tex]a^{2} = c^{2} - b^{2}[/tex]
[tex]a^{2} = 14^{2} - 10^{2}[/tex]
[tex]a^{2} = 196 - 100[/tex]
[tex]a^{2} = 96[/tex]
[tex]\sqrt{a^2} = \sqrt{96}[/tex]
[tex]a = 9.7979[/tex] ⇒ 9.8
Answer:
The value of x=4√6cm or √96cm
Step-by-step explanation:
According to Pythagoras theorem,
Hypotenuse²=Perpendicular²+Base²
H²=P²+B²
Hypotenuse given=14cm
Base=10cm
Perpendicular=x
14²=P²+10²
196=P²+100
196-100=P²
96=P²
√96=P
4√6cm=x
Okay so i need to know the area of the rectangle on the inside its 5ft on the right side its 6ft and on the bottom its 5ft please and thank you :)
Answer:
30ft^2
Step-by-step explanation:
Area of a rectangle = Length * Width
Given
Length = 6ft
Width = 5ft
Substitute
Area of the rectangle = 6ft *5ft
Area of the rectangle = 30ft^2
Hence the area of the rectangle is 30ft^2

write a quadratic equation with a double root of -5
Answer:
x^2 =5
Step-by-step explanation:
Answer:
x² + 10x + 25 = 0
Step-by-step explanation:
Given that x = - 5 is a root then (x + 5) is a factor
Since it is a double root then (x + 5)² so equation is
(x + 5)² = 0 ← expand factor using FOIL
x² + 10x + 25 = 0

An artist is painting flower pots that each require 1/32 gallon of paint. What is the maximum number of flower pots the artist can paint with 3/4 gallon of paint?
Answer:
24 flower pots
Step-by-step explanation:
Fraction of paint required per flower pot = 1/32
Number of pots that can be painted with 3/4 galoons of paint :
Total Fraction of paint had / fraction of paint required per flower pot
3/4 ÷ 1/32
3/4 * 32 / 1
(3*32) / 4
96 /4
= 24 flower pots
