Answer:
m<bec = 60
Step-by-step explanation:
3x +2x +x = 180 (combine like terms)
6x = 180 (divide 180 by 6 to get x alone on one side of the equation)
x = 30
BUT you're not done yet because it asked for m<bec which is 2x so you have to multiply 30(2) which is 60

SA= 2 pie r square + 2 pie rh, solve for h please
Answer:
[tex]\huge \boxed{h= \displaystyle \frac{SA}{2\pi r} -r}[/tex]
[tex]\rule[225]{225}{2}[/tex]
Step-by-step explanation:
[tex]SA=2\pi r^2 +2\pi rh[/tex]
Subtracting [tex]2\pi r^2[/tex] from both sides:
[tex]SA-2\pi r^2 =2\pi rh[/tex]

The product of five and a number, increased by 9 is equal to fifteen less than three times then
number. Write an equation, solve, and find the number.
Answer:
x = -12
Step-by-step explanation:
Let x be the number.
The product of 5 and x increased by 9 is equal to 15 less than 3 times x.
5x + 9 = 3x - 15.
We can isolate x, getting (5-3)x = -15-9
Then we can solve:
2x = -24
x = -12.
The required number is -12.
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.

Find the point-slope equation for
the line that passes through the
points (1,-9) and (-10, 101). Use
the first point in your equation.
y + 9 = [ ? ](x-[ ])
Answer:
Below in bold.
Step-by-step explanation:
The slope of the line = (101 - -9) / (-10 - 1)
= 110/ -11
= -10
The required equation is y + 9 = -10(x - 1)
4. A rock is placed in a graduated cylinder with 40-mL of water in it. The water level rises to 60-mL. When placed on a balance scale it takes 54 grams of gram stackers to balance the scale. What is the density of the rock?
Answer:
2.7 [tex]g/mL[/tex]
Step-by-step explanation:
The density of an object will be its mass over volume.
We know that the mass of this rock is 54 grams because it took 54 grams of gram stackers to balance the scale. If we have a balanced scale, that means the amount of weight on either side is equal. So the mass is 54 grams.
Also, we can tell that the volume of the rock is 20 mL. This is because, according to Archimedes principle, if you put an object in water, the amount of water displacement will be it's volume. So the amount of water displacement is [tex]60-40=20[/tex] mL.
Density is mass over volume, so the density is [tex]54\div20 = 2.7[/tex]. Density is measure in mass over volume, so [tex]g/mL[/tex].
So 2.7 [tex]g/mL[/tex] is the density of the rock.

What properties can be used to solve 7y-15=-29. Identity property of multiplication,addition property of equality ,distributive property,inverse property of mulplication,commutative property of addition
Answer:
Addition Property of Equality.
Inverse property of multiplication.
Step-by-step explanation:
Given the equation:
[tex]7y-15=-29[/tex]
First of all, let us use Addition Property of Equality.
According to the property, if we add a number on both sides of an equality, there is no change in the equality.
In other words, the equality will be same if we add the same number on Left Hand Side and Right Hand Side of the equality.
First of all, let us add 15 on both sides of the equality:
[tex]7y-15+15=-29+15\\\Rightarrow 7y=-14[/tex]
Now, let us Inverse property of multiplication.
i.e. Multiplication of a number with its inverse is equal to 1.
[tex]a\times \frac{1}{a} = 1[/tex]
So, let us multiply the given equation with [tex]\frac{1}7[/tex]
[tex]7y \times \dfrac{1}{7}=-14 \times \dfrac{1}{7}\\\Rightarrow 1y =-2\\\Rightarrow y=-2[/tex]
The properties used are:
Addition Property of Equality.
Inverse property of multiplication.

An object is moving at a speed of 3 kilometers per hour. Express this speed in feet per
minute. Round your answer to the nearest whole number.
The speed of the object in feet per minute to nearest whole number is 164feet/min
Speed is the ratio of the distance to the time of an object. Mathematically;
Speed = Distance/Time
Given the following
Speed = 3km/hr
Using the conversion ratio
1km = 3280.84feet
3km = x
Cross multiply
x = 3 * 3280.84
x = 9,842.52feet
Convert 1 hour to minute
1 hour = 60minutes
Get the speed in feet per minutes
Speed in feet/minutes = [tex]\frac{9,842.52}{60}[/tex]
Speed in feet/minutes = 164.042 feet/minutes
Hence the speed of the object in feet per minute to nearest whole number is 164feet/min

The speed in feet per minute is 164.
Given the following data:
Speed = 3 kilometers per hour.In this exercise, you're required to convert the value of the speed given in kilometers per hour to feet per minute.
Conversion:
1 kilometer = 3280.84 feet
3 kilometer = X feet
Cross-multiplying, we have;
X [tex]= 3280.84[/tex] × [tex]3[/tex]
X = 9842.50 feet
Since we know that one (1) hour is equal to sixty (60) minutes, we would divide the value of X by 60 in order to convert it to feet per minute.
[tex]X = \frac{9842.50}{60}[/tex]
X = 164.042 feet per minute.
To the nearest whole number;
X = 164 feet per minute
Therefore, the speed in feet per minute is 164.

Which figure represents an undefined term?
Answer: 4th figure , where XY is a line.
Step-by-step explanation:
There are 3 undefined terms : 1) point 2) line 3 ) planeFrom up to down, The first figure is representing ray( end point at X ) which is an defined term and it is defined as "A ray is a line with one end point."
The second figure is representing a line segment with 2 end-points at X and Y and it is and defined term and it is defined as "A line segment is a line with 2 end points."
The third figure is a joint of two rays and they are making an angle which is again an defined term.
The last figure is representing a line which has no endpoints and is an undefined term.
Hence, the last figure is representing an undefined term "line".
What simple interest rate would allow $6000 to grow to an amount of $14550 in 10 years?
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ \: 14.25 \: \% \: }}}}}[/tex]
Step-by-step explanation:
Given,
Principal ( P ) = $ 6000
Amount ( A ) = $ 14550
Time ( T ) = 10 years
Rate ( R ) = ?
Finding the Interest
The sum of principal and interest is called an amount.
From the definition,
[tex] \boxed{ \sf{Amount = \: Principal + Interest}}[/tex]
plug the values
⇒[tex] \sf{14550 = 6000 + Interest}[/tex]
Swap the sides of the equation
⇒[tex] \sf{6000 + Interest = 14550}[/tex]
Move 6000 to right hand side and change its sign
⇒[tex] \sf{Interest = 14550 - 6000}[/tex]
Subtract 6000 from 14550
⇒[tex] \sf{Interest = \: 8550 \: }[/tex]
Interest = $ 8550
Finding the rate
[tex] { \boxed{ \sf{Rate = \frac{Interest \times 100}{Principal \times Time}}}} [/tex]
plug the values
⇒[tex] \sf{ Rate = \frac{8550 \times 100}{6000 \times 10} }[/tex]
Calculate
