Answer:
80 = x
Step-by-step explanation:
The base angles are the same if the side lengths are the same
The unmarked angle is 50 degrees
The sum of the angles is a triangle is 180 degrees
180= 50+50+x
180 = 100 +x
180 -100 = 100+x-100
80 = x
Answer:
80°
Step-by-step explanation:
In an isosceles triangle, if the two sides are the same length, then the two angles formed on the base line are equal.
The other angle on the base line is also equal to 50°.
Angles in a triangle add up to 180°.
x° + 50° + 50° = 180°
x° + 100° = 180°
x° = 180° - 100°
x° = 80°
the pressure p of a given gas in inversely proportional to the cube root of its volume, V at a constant temperature, When V is 64, p=6 . calculate (a) p when v=27 (d) v when f= 2
Answer:
see explanation
Step-by-step explanation:
Given that p is inversely proportional to [tex]\sqrt[3]{V}[/tex] then the equation relating them is
p = [tex]\frac{k}{\sqrt[3]{V} }[/tex] ← k is the constant of proportion
To find k use the condition when V = 64, p = 6 , thus
6 = [tex]\frac{k}{\sqrt[3]{64} }[/tex] = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )
24 = k
p = [tex]\frac{24}{\sqrt[3]{V} }[/tex] ← equation of proportion
(a)
When V = 27, then
p = [tex]\frac{24}{\sqrt[3]{27} }[/tex] = [tex]\frac{24}{3}[/tex] = 8
(b)
When p = 2, then
2 = [tex]\frac{24}{\sqrt[3]{V} }[/tex] ( multiply both sides by [tex]\sqrt[3]{V}[/tex] )
2[tex]\sqrt[3]{V}[/tex] = 24 ( divide both sides by 2 )
[tex]\sqrt[3]{V}[/tex] = 12 ( cube both sides )
V = 12³ = 1728

find the area of a circle
Answer:
28.26 square feet
Step-by-step explanation:
Area of a circle is: [tex]A=\pi r^2[/tex]
'r' is the radius.
We are given the diameter of 6ft. Since the diameter is twice the radius, the radius is 3 ft.
6/2 = 3
Using 3.14 for pi:
[tex]A=3.14*3^2\\\rightarrow 3^2=9\\A=3.14*9\\\boxed{A=28.26}[/tex]
The area of the circle should be 28.26 square feet.
Answer:
28.26 ft²
Step-by-step explanation:
If the diameter is 6 feet, then the radius is 3 feet since 2r=d
The area formula in this case is 3.14×r² since it says "Use 3.14 for π".
3.14×3²=
3.14×9=
28.26 ft²
At which root does the graph of f(x) = (x – 5)3(x + 2)2 touch the x-axis?
Answer:
x = -2
Step-by-step explanation:
The root will touch the axis and bounce off when the exponent is even. In that case, that means (x + 2)² is the binomial that will bounce. Therefore, the root which bounces and touches the x-axis is x = -2.
which represents the equation of the line?
Answer:
D: y= -2x -1
Step-by-step explanation:
The line crosses the y axis at -1 and using the "rise over run" phrase you can tell that the next point is 2 up and 1 over (2/1 =2) the line is also negative because it moves down from left to right. Therefore, y= -2 -1

Answer:
26.6667
Step-by-step explanation:
.15x=100
Divide each side by .15.
x=666.6667
.04(666.6667)=26.6667
Answer:
26(approx.)
Step-by-step explanation:
15/100 times x = 100
3/20 times x = 100
3x/20 = 100
3x = 2000
X= 666 2/3
So,
4/100 x 666.67
1/25 x 666.67 = 26

Answer: #4 C Domain is x such that x is greater than -1 (all real numbers greater than -1)
#5 B Points C, F & G
Step-by-step explanation: Look at the coordinate of the vertex. It is at (-1, 1) so the -1 is the lowest number in the Domain (running left to right). The attows at the right ends mean that the lines go to infinity. The symbol ∈ means "belongs to" the R (special font not available here) means "all real numbers.
The y-value, 1 is not relevant here, as the Range (up and down, like a mountain range) is infinity, and the arrows keep going forever. ∈R means all real numbers.
For the Triangle: First ,imagine a box with the boundaries matching the domain and range given, so the left side is at -2, the right side is at 6 [Domain] and the top and bottom are at 5 and -1 [Range]
Pick the points that are on the boundary lines. C is at (6,3) on the right boundary, F is at (2,-1) on the bottom boundary and G is at (-2,5) at the corner where the top and left sides meet.

I will give you brainliest :) Which of the following values are in the domain of the function graphed below? Check all that apply.
The domain is the x value of the graph. I suggest going down the choices and finding which of them is an x value of the function...
Since there are 5 ticks and the 5th tick is 10, we can tell that each tick stands for 2 units. I would label them before we start.
Okay...
-4 cannot be an option, because the x value, -4 is on the 2nd tick mark and the function only goes to the 1st tick.
0 is an option!
5 is not.
-1 is!
4 is!
-2 is!
so we have B D E F

Answer: 2:1
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations
R = M+18 (Rita(R) has 18 more Eminem CDs than Mimi(M))
M/R= 5/8 (ratio)
Solving for M (Mimi's cds) in the second equation
8M=5R
M=5/8R
Replacing M =5/8R in the first equation
R=5/8R +18
R-5/8R= 18
3/8R =18
R=18 /(3/8)
R= 48 CDS
Back in the second equation
8M =5R
8M=5(48)
8M= 240
M= 240/8
M=30 CDS
If Rita gives 22 CDs to Mimi
R=48-22=26
M=30+22=52
The new ratio of the number Eminem CDs Mimi has to the number of Eminem CDs Rita has IS:
M/R= 52/26= 26x2 /26 x1 = 2/1 =2:1

What is a system of equations for the following situation? A group of 14 people went to see a movie. The cost to go to the movie is $12 for an adult and $8 for a child. The total cost for the group was $144.
Answer:
144=12x+8y
x+y=14
Step-by-step explanation:
Answer:
12x + 8 (14 - x ) = $ 144
x + (14-x) = 14
Step-by-step explanation:
Total number of people = 14
Let the number of adults be x and the number of children be ( 14 - x)
Total cost for the group = $144
i.e., 12x + 8 ( 14-x) = 144
12x + 112 - 8x = 144
4x + 112 = 144
4x = 144-112
4x = 32
x = 32/4
x = 8
Number of adults = x = 8
Number of children = 14 - x = 14 - 8 = 6

Choose the answer based on the most efficient method as presented in the lesson.
If the first step in the solution of the equation -8 - 7x = -5x - 10 is "add 10," then what should the next step be?
add 7x
add 8
add 5x
Answer:
The answer is add 7x.
Step-by-step explanation:
When the first step is to add 10 to both sides :
[tex] - 8 - 7x = - 5x - 10[/tex]
[tex] - 8 - 7x + 10 = - 5x - 10 + 10[/tex]
[tex] - 7x + 2 = - 5x[/tex]
Next, you have to add 7x to both sides to eliminate -7x on the left side :
[tex] - 7x + 2 = - 5x[/tex]
[tex] - 7x + 2 + 7x = - 5x + 7x[/tex]
[tex]2 = 2x[/tex]
Answer:
add 7x
Step-by-step explanation:
This would be the answer because if you have already added 10 to the right side of the equation and have erased the constant, you would then need to erase the variable on the other side to make it equal. The variable on the other side is 7x, which gives you the answer.
Lowell has a credit card that uses the adjusted balance method. For the first
10 days of one of his 30-day billing cycles, his balance was $1360. He then
made a purchase for $470, so his balance jumped to $1830, and it remained
that amount for the next 10 days. Lowell then made a payment of $740, so
his balance for the last 10 days of the billing cycle was $1090. If his credit
card's APR is 28%, which of these expressions could be used to calculate the
amount Lowell was charged in interest for the billing cycle?

He squeezed StartFraction 4 over 17 EndFraction cups from the first orange, StartFraction 3 over 10 EndFraction cups from the second orange, StartFraction 9 over 20 EndFraction cups from the third orange, StartFraction 3 over 11 EndFraction cups from the fourth orange, and StartFraction 7 over 15 EndFraction cups from the fifth orange. Patel estimates that he needs 2 cups of orange juice for his family. About how much more orange juice does he need to reach his estimate? One-sixth cups Five-sixths cups 1 and two-thirds cups 1 and StartFraction 5 over 6 EndFraction cups
Answer:
3089/11220
Approximately = 0.2753
Step-by-step explanation:
Patel estimates that he needs 2 cups of Orange juice.
But let's know the amount he already has.
4/17 + 3/10 + 9/20 + 3/11 + 7/15
= 3/10 + 9/20 + 7/15 + 3/11 + 4/17
=( 18 + 27 + 28)/60 + (51+44)/187
= 73/60 + 95/187
=( 13651 + 5700)/11220
= 19351/11220
= 1(8131/11220)
So to complete it two he needs ( 11220-8131)/11220= 3089/11220
Approximately = 0.2753
