Answer:
[tex]\huge\boxed{IJ = 9}[/tex]
Step-by-step explanation:
Given that J is on line segment IK.
So, it is like:
I______?_______J___6___K
|<--------------------15---------------->|
We know that:
IK = IJ + JK
Where IK = 15 and JK = 6
15 = IJ + 6
Subtracting 6 to both sides
IJ = 15 - 6
IJ = 9

Answer:
Peter walks at a rate of 13/4 miles per hour.
Step-by-step explanation:
Peter walks at a rate of 13/4 miles per hour because every hour, represented by x, he walks 3.25 hours or 13/4. y is the total miles he walked so if he walks two hours the y would equal 6.5 or 26/4 and the x would equal 2.

Answer: No it is closer to 9/11
Step-by-step explanation:
Answer: It is closer to 9/11
Step-by-step explanation: 41/50 in decimal form is 0.82.
9/11 in decimal form is 0.8181, which rounds up to 0.82
10/11 in decimal for is 0.9090, which rounds up to 0.91.
So,
41/50 = 0.82
9/11 =0.8181 OR 0.82
10/11 = 0.9090 OR 0.91

Step-by-step explanation:
If m < A = 4x + 12 and x = 15, is < A acute, obtuse, or right? Justify your answer.
Step-by-step explanation:
Angle A = 4x + 12 = 4(15) + 12 = 72°.
Acute is for angles that are less than 90°.
Obtuse is for angles that are between 90° and 180°, not inclusive.
Right is for angles that are 90°
Hence the answer is acute.
The angle is an acute angle
An acute angle is an angle that is less than 90 degrees
An obtuse angle is an angle that is greater than 90 degrees and less than 180 degrees
In order to determine which type of angle it is, solve for angle A
4x + 12
4(15) + 12
60 + 12 = 72
The angle is acute because it is less than 90 degrees

Answer:
Square root 8 over three, (square root of 4)/2, and pi/3.
Step-by-step explanation:
First of all, square the radicals to make solving this easier. Squarer root 8 over three will become 8/9, and square root 4 over 2 will now become 4/4, which is 1. Pi/3 is greater than 1, so we can now order this from least to greatest. 8/9 is the least, 1 is the second greatest value, and pi/3 is the greatest value.
Answer: 8squared/3 4squared/2 Pi/3
Step-by-step explanation:
8 squared = 2.8... = 2.8/3 (least)
4 squared = 2 = 2/2 = 1 (second least)
Pi over 3 = 3.14159.../3 = 1 .14159/3 (greatest)

What is the equation of a line with a slope of –2 that passes through the point (6, 8)?
Answer:
The answer is
y = - 2x + 20Step-by-step explanation:
To find the equation of the line given a point and slope we use the formula
[tex]y - y_{1} = m(x - x _{1})[/tex]
where
m is the slope
( x1 , y1) is the point
From the question
The point is (6, 8) and
slope - 2
The equation of the line is
[tex]y - 8 = - 2(x - 6) \\ y - 8 = - 2x + 12 \\ y = - 2x + 12 + 8[/tex]
We have the final answer as
y = - 2x + 20Hope this helps you

What is 90% of 81?
X
Answer:72.9
Step-by-step explanation:
Answer:
72.9
Step-by-step explanation:
Fractions method:
[tex]81*\frac{90}{100}[/tex] because 90/100 is the same thing as 90%
That gives us 7290/100, from 81*90/100
Simplify: =729/10 = 72.9
Decimals method:
81*9 = 729, add in decimal and that's 72.9
Cross-multiplication:
90 100
? 81
This is read as 90 to 100, (as a ratio) so how many to 81? To solve, cross-multiply - 81*90=7290, then divide by 100 to get 72.9.

Sarah is working as a truck driver. She gets paid $100 everyday and then $22 per hr driving. How many hours does sarah have to work to make $276 in one day
Answer:8
Step-by-step explanation: she makes $100 a day so you would subtract that from the total (276) then you would divide the remainder (176) by the amount she makes an hour (22) then you would end up with 8 hours
Answer:
8 hours
Step-by-step explanation:
For $22=1 hour
For $1=1/22 hours
For $176=176/22 hours=8 hours
And she gets also $100 extra
So for $276 she works 8 hours.

In a stationary store,pencils have one price and pens have another price.Two pencils and three pens cost 78 cents.However, 3 pencils and 2 pens cost 72 cents . How much does one pencil cost?
Answer:
12¢
Step-by-step explanation:
Let the unit price of a pencil be x and the unit price of a pen be y.
2x+3y=78¢
3x+2y=72¢
(2x)+3y=78¢
(3x)+2y=72¢
=2x=78¢-3y
=2x/2=78¢/2+3y/2
=x=36¢-1.5y
You then use the equation 3x+2y=72¢.
3(36¢-1.5y)+2y=72¢
=117¢-4.5y+2y=72¢
=117¢-72¢=4.5y-2y
=45¢=2.5y
=45¢/2.5=y
=18¢=y
So a pen costs 18¢.
You then use x=36¢-1.5y
x=36¢-1.5(18¢)
=x=36¢-27¢
=x=12¢
Therefore, a pencil costs 12¢.

Answer:
Frank earns $200.
His dad earns $800.
Step-by-step explanation:
Giving the following information:
His dad makes 4 times as much money as him each week. Each week their income adds up to 1.000 dollars.
We know that:
x= Franks income
4x= Dads income
y= total income
y= x + 4x
1,000= 5x
1,000/5=x
200=x
Frank earns $200.
His dad earns $800.
AG bisects ∢RAZ , and ∢RAG =. 8x+5 , and ∢ZAG = 4 x + 29 find the x .
Answer:
x = 6
Step-by-step explanation:
Given AG bisects ∠ RAZ , then
∠ RAG = ∠ ZAG , that is
8x + 5 = 4x + 29 ( subtract 4x from both sides )
4x + 5 = 29 ( subtract 5 from both sides )
4x = 24 ( divide both sides by 4 )
x = 6

What is a line segment?A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.
Given that FG = (2x) meters, GH = 1,000 meters, and FH = 1,200 meters,
The value of x will be calculated by making an equation for the line segment below:-
FG + GH = FH
2X+1000=1200
2X = 1200 - 1000
2X = 200
X = 100 meters
2X + 1000= 1200

one-half the cube of m subtracted by 4 *
Answer:
[tex]\frac{m^3}{2} - 4[/tex]
Step-by-step explanation:
Required
Determine an expression for the given statement
The expression can be rewritten as:
one-half * the cube of m subtracted by 4
Convert each statement to mathematical expressions:
One half = [tex]\frac{1}{2}[/tex]
The cube of m = [tex]m^3[/tex]
one-half * the cube of m = [tex]\frac{1}{2} * m^3[/tex]
At this stage, we have:
[tex]\frac{1}{2} * m^3[/tex] subtracted by 4
This gives:
[tex]\frac{1}{2} * m^3 - 4[/tex]
[tex]\frac{m^3}{2} - 4[/tex]
Hence, The corresponding expression is [tex]\frac{m^3}{2} - 4[/tex]
One-half the cube of m subtracted by 4 is [tex]0.5\sqrt[3]{m} -4[/tex]
Based on the information given, one-half the cube of m subtracted by 4 is expressed as:
[tex]0.5\sqrt[3]{m} -4[/tex]Note that the cube of m is expressed as [tex]\sqrt[3]{m}[/tex]The half of the cube of m will be given as [tex]0.5\sqrt[3]{m}[/tex]Subtracting 4 from the result will give the final expression as [tex]0.5\sqrt[3]{m} -4[/tex]

Answer:
180
Step-by-step explanation:
2 1/4 ft = 9/4 ft, so is a length equivalent to 9 cubes.
1 ft = 4/4 ft, so is a length equivalent to 4 cubes.
1 1/4 ft = 5/4 ft, so is a length equivalent to 5 cubes.
Then the volume of the prism is ...
