Answer:
The two missing angles are 20 and 30 degrees.
Step-by-step explanation:
Quadrilaterals have four interior angles that add up to 360 degrees.
So we have two angles that are 240 degrees and 70 degrees.
If 240 + 70 = 310
That means the other two angles added together must be equal 50.
Because 360 - 310 = 50
So their ratio is 2:3 which means they have five equal parts.
Which would mean 50/5 = 10
2 x 10 = 20
3 x 10 =30
This means the missing angles are 20 and 30 degrees.
Hope this helped you!

Answer:
d.
The actual price is 12.5% higher than the expected price
Step-by-step explanation:
The percent relation of the actual price and the expected price is 12.5%
What is the consumer price index?The consumer price index measures the changes in price of a basket of good. It is used to measure inflation.
Price of the cast iron today = $28.35 x (166/100) = $47.06
The percent relation of the actual price and the expected price = ($52.95/$47.06) - 1 = 12.5%

Answer:
C. An elephant walks with a speed of 15 steps a minute. How long was the elephant walking if she walked without stopping for 480 steps?
Step-by-step explanation:
C yields the equation of [tex]15x=480[/tex], because 15 stands for steps/minute, 480 for steps, so [tex]x[/tex] must stand for minutes.
For your entertainment:
A gives [tex]x = 480 \cdot 15[/tex].

Analyze the following image and state
Line of Symmetry
Coordinates of the Vertex, X - intercepts, Y - Intercepts.
Whether the graph is positive or negative.
Answer:
The x-intercept is where the graph crosses the x-axis, so in this case, the x-intercepts are (-4, 0) and (-2, 0).
The y-intercept is where the graph crosses the y-axis, so in this case, the y-intercept is (0,8).
The line of symmetry splits the graph in two equal halves, and it is x=-3.
Finally, because this graph opens up, the graph is positive.

A group of 15 people each bought both a book that cost x dollars and a bookmark that cost $1. A group of 3 people each bought both a book that cost x dollars and a backpack that cost $36. Both groups spent the same amount of money. What is the price of the book?
Answer:
$1.40
Step-by-step explanation:
Answer:
The price of the book is $7.75.
Step-by-step explanation:
Let's first establish an equation.
If I buy a book costing [tex]x[/tex] dollars and a bookmark costing 1 dollars, I will have spent [tex]x + 1[/tex] dollars. So a group of 15 people doing the same will have spent [tex]15(x+1) = 15x + 15[/tex] dollars.
Analogously, the group of 3 people has spent [tex]3(x+36) = 3x + 108[/tex] dollars.
Since we know that both groups spent the same amount of money, we can set the two expressions equal to each other:
[tex]15x+15=3x+108\\12x=93\\x=7.75[/tex]
Because [tex]x[/tex] was the price of the book, which was asked for in the question, we conclude that the answer is $7.75.
A jar contains sugar. The jar and the sugar have a total weight of 850 g. Anna uses 2/3 of the sugar. The jar and the sugar now have a total weight of 530 g. Work out the weight of the jar.
Answer:
[tex]J = 370g[/tex]
Step-by-step explanation:
Given
Represent the weight of the Jar with J and the sugar with S
Initially, we have:
[tex]J + S = 850g[/tex]
After 2/3 of sugar is removed we have:
[tex]J + S -\frac{2}{3}S= 530g[/tex]
Required
Determine the weight of the jar
[tex]J + S = 850g[/tex] --- (1)
[tex]J + S -\frac{2}{3}S= 530g[/tex] --- (2)
Simplify (2)
[tex]J + S -\frac{2S}{3}= 530g[/tex]
Take LCM
[tex]J + \frac{3S - 2S}{3}= 530g[/tex]
[tex]J + \frac{S}{3}= 530g[/tex]
Make S the subject in (1)
[tex]J + S = 850g[/tex]
[tex]S = 850g - J[/tex]
Substitute 850g - J for S in [tex]J + \frac{S}{3}= 530g[/tex]
[tex]J + \frac{850g - J}{3}= 530g[/tex]
Multiply through by 3
[tex]3 * J + 3*\frac{850g - J}{3}= 530g * 3[/tex]
[tex]3J + 850g - J= 1590g[/tex]
Collect Like Terms
[tex]3J - J= 1590g-850g[/tex]
[tex]2J= 740g[/tex]
Make J the subject
[tex]J = \frac{1}{2} * 740g[/tex]
[tex]J = 370g[/tex]
The jar weighs 370g

Answer:
x=7
Step-by-step explanation:
Let's solve your equation step-by-step.
5x+3−2x=24
Step 1: Simplify both sides of the equation.
5x+3−2x=24
5x+3+−2x=24
(5x+−2x)+(3)=24(Combine Like Terms)
3x+3=24
3x+3=24
Step 2: Subtract 3 from both sides.
3x+3−3=24−3
3x=21
Step 3: Divide both sides by 3.
Answer: x=7
Step-by-step explanation:
Given
5x + 3 - 2x = 24
Subtract both sides by 3
5x + 3 - 3 - 2x = 24 - 3
5x - 2x = 21
Simplify
3x = 21
Divide both sides by 3
3x / 3 = 21 / 3
x=7

Answer:
125°
Step-by-step explanation:
By exterior angle theorem:
(3x - 70)° = 60° + x°
(3x - 70)° - x°= 60°
(3x - 70 - x)° = 60°
(2x - 70)° = 60°
2x - 70 = 60
2x = 60 + 70
2x = 130
x = 130/2
x = 65
(3x - 70)° = (3*65 - 70)° = (195 - 70)° = 125°

5. A mountain has a base and peak that are inaccessible. At point A, the angle of elevation of the peak is
30°. One kilometer closer to the mountain, at point C, the angle of elevation of 35º. Find the height
PB of the mountain.
Answer:
1.366km
Step-by-step explanation:
The height of the mountain is [tex]3.34Km[/tex]
Right angle triangle:A diagram of right angle triangle PBA is attached below which describe the situation as given in the question.
Let us consider that H represent the height of mountain.
Angle of elevation at point A and C shown in the diagram.
Apply tan function in triangle CBP.
[tex]tan(35)=\frac{H}{x} \\\\H=xtan(35)=0.7x.........(1)[/tex]
Apply tan function in triangle ABP.
[tex]tan(30)=\frac{H}{x+1}\\ \\(x+1)tan(30)=H\\\\(x+1)=\sqrt{3}H\\ \\x=\sqrt{3}H-1........(2)[/tex]
Substituting the value of equation 2 into equation 1.
[tex]H=0.7(\sqrt{3}H-1)\\\\H=1.21H-0.7\\\\0.21H=0.7\\\\H=0.7/0.21=3.34Km[/tex]
Hence, The height of the mountain is [tex]3.34Km[/tex]

The relationship between the intensity of sound((w)/(m^(2)))and the distance from the source of sound is represented by the equation (i)=((k)/(d^(2))).If you sit only one meter away from the stage at a rock concert the intensity of sound is about 0.1(w)/(m^(2)). If vanessa does not want the sound intensity to be more than 0.001(w)/(m^(2)) how close to the stage can she sit?
Answer:
10 m
Step-by-step explanation:
We are given that the relationship between intensity of sound and distance from the source is given by
Intensity (I)=[tex]\frac{k}{d^2}[/tex]
Where I=Intensity
d=Distance of sound from the source
If distance d=1m
Intensity, I=0.1[tex]w/m^2[/tex]
We have to find how close she can to the stage if vanessa does not want the sound intensity to be more than 0.001(w)/(m^(2)).
Using the formula
[tex]0.1=\frac{k}{1}[/tex]
[tex]k=0.1[/tex]
[tex]\frac{0.1}{d^2}\leq 0.001[/tex]
[tex]\frac{0.1}{0.001d^2}\leq 1[/tex]
[tex]\frac{0.1}{0.001}\leq d^2[/tex]
[tex]100\leq d^2[/tex]
[tex]10\leq d[/tex]
[tex]d=10 m[/tex]
Hence, she can sit 10 m away from the stage.

Answer:
x = [tex]\sqrt{10}[/tex]
Step-by-step explanation:
The 2 right triangles and the outer right triangle are similar, then ratios of corresponding sides are equal, that is
[tex]\frac{x}{5}[/tex] = [tex]\frac{2}{x}[/tex] ( cross- multiply )
x² = 10 ( take the square root of both sides )
x = [tex]\sqrt{10}[/tex]
Answer:
√10
Step-by-step explanation:
taking the smallest triangle;
y as the hypotenuse, x as the adjacent side, 2 as the opposite side
then: y²=x²+2²
x²=y²-2²= y²-4
taking the other triangle;
z as the hypotenuse, x as the adjacent side, 5 as the opposite side
then: z²=x²+5²
x²=z²-5² = z²-25
take both equations,
x²= y²-4
x²= z²-25
y²-4= z²-25
y²= z²-25+4 = z²-21
taking the biggest triangle (whole triangle);
(5+2)= 7 as the hypotenuse, z as the adjacent side, y as the opposite side
then; 7²=z²+y²
z²+y²=7² =49
but y²= z²-21;
z²+y² =49
z²+ z²-21 =49
2z²-21=49
2z²=49+21= 70
z²= 70/2 = 35
take x²= z²-25
x²= 35-25 = 10

You bought a car for $5,000. Each year it depreciates in value by 8.5% which equation can be use to find the value, v, of the car x years after it was purchased?
Answer:
I believe this is the answer
V=5000(1•0.085)^x
Step-by-step explanation:
sorry if its incorrect i just wanted to help
"v = 5000 * (1-0.085)x" is the formula that is used to determine the car's worth.
What is depreciation?An asset loses value over time as a result of use, damage, or obsolescence. Depreciation is the measurement of this decline. Depreciation, or a decline in asset value, can be brought on by a variety of other variables, such as bad market conditions, etc.
Given, You bought a car for $5,000. Each year it depreciates in value by 8.5%
In this case, we have the following formula:
v = C. (1 - r)ˣ
Where C is the original value of the car, r is the depreciation rate and x is the time in years
Equation to find the value = 5000 * (1- 0.085)ˣ
Therefore, the equation that helps in calculating the value of the car is
"v = 5000 * (1- 0.085)ˣ".
