Answer:
30° , 170°
Step-by-step explanation:
Let the remaining two angles be 3x & 17x. As it is a quadrilateral , the sum of all the angles of quadrilateral is 360°. So,
[tex]3x + 17x + 60 + 100 = 360[/tex]
[tex] = > 20x + 160 = 360[/tex]
[tex] = > 20x = 360 - 160 = 200[/tex]
[tex] = > x = \frac{200}{20} = 10[/tex]
Putting the value of x , remaining angles are
(3×10 = 30°) & (17×10 = 170°)
Step-by-step explanation:
the missing angles 3:173x+17x+60+100=360°20x+160=360°20x=360-16020x=200°divide both sides by 20X=10substitute X=10 in 3x and 17x3(10)=30°17(10)=170°Please Help ASAP!!!!!!!!!!!!

. Mark's profile picture is 4 inches tall, but his actual height is 76 inches. What is the scale factor from his profile picture to his actual height?
Scale factor =
19
72
16
38
3b. If the profile picture of Mark's sister is 3.5 inches tall, how tall is her actual height?
Her actual height is _____ inches.
70
82
59.5
66.5
Step-by-step explanation:
Answer: 19, because all you´re doing for mark is dividing his actual height from the profile picture.
Marks sister: 66.5, because you will take her height (3.5) and you will put x over 3.5 in fraction form. Then you will take marks profile picture height, and put it in fraction form (76 over 4) then you will cross multiply 3.5 and 76 which will give you 266. Then you´ll divide 266 by 4 which would give you 66.5

Answer:
1,200 cubic cm
Step-by-step explanation:
First, you separate it into two prisms, which gives you two different volume formulas.
14*20*2 = 560
20*4*8 = 640
You then add the two volumes together, which equals 1,200
Answer:
sorry wish i could help....
Step-by-step explanation:
The volume of a cylinder is 72 cm. If the radius is 3 cm, what is the height

A. 12 cm
B. 8 cm
C. 24 cm
D. 4 cm
Tell whether the triangle is right or not
Answer: Solved below...
Answer: Yes, that is a right triangle.
Step-by-step explanation:
To tell whether this is a right triangle or not you use a^2 + b^2= c^2
c is the hypotenuse the hypotenuse is the longest side of a right triangle, opposite the right angle. A and B can be either of the triangles sides.
To get this answer: 80^2+39^2 = 89^2
6400 + 1521 = 7921
7921=7921
Since they are the same this IS a right triangle. Here is a little help for if the a question asks if you have a right acute or obtuse. To tell if you have an acute triangle the sign will be a greater than sign for ex) 180 > 169. If you have a obtuse triangle the sign would be a less than sign for ex) 120 < 200.
Here is a problem like that if you do not understand:
6^2 +12^2 = 13^2 ( remember c is the hypotenuse)
36+144= 169
180 > 169

There were 45 runners sister erased in the first half of the race 2/3 of them dropped out in the second half of the race to fifth of the remaining runners chopped out how many runners finish the race
Answer:
9 runners
Step-by-step explanation:
Number of runners who started race = 45
Fraction that dropped off in the first half =. 2/3
Fraction of the remaining that dropped of in the second half = 2/5
Number of runners who dropped off in the first half :
(2/3) * 45 = (2 * 45) / 3 = 90 /3 = 30 runners
Runners left = (45 - 30) = 15
Number who dropped off in the second half :
(2/5) * 15 = (2 * 15) / 5 = 30 /5 = 6 runners
Number of runners who finished the race :
(15 - 6) = 9 runners

Paige plans to go to the fair with three of her
friends. She needs to earn at least $60 to
attend the fair. If Paige earns $7.50 per hour
babysitting, how many hours will she need to
work in order to have enough money to go to
the fair with her friends?
Answer:
how many hours will she need to work in order to have enough money to go to the fair with her friends? $60/$7.5/h = 8h
Step-by-step explanation:
Answer:
8 hours
Step-by-step explanation:
60=7.50x
60 will represent how much money she needs to earn.
x= number of hours Paige needs to work
[tex]\frac{60}{7.50} =\frac{7.50x}{7.50}[/tex]
[tex]x=8[/tex]
Paige needs to work 8 hours in order to have enough money to go to the fair with her friends.
If the original quantity is 8 and the new quantity is ,2 what is the percent decrease?
Answer: 75%
Step-by-step explanation:
75% of 8 is 6.
8 was decreased by 6 to get 2.
8 was decreased by 75% of its initial value to get 2.
Hope this helped!
Answer:
75%.
Step-by-step explanation:
8 - 100%
2 - x
[tex]\dfrac{8}{100 \%}=\dfrac{2}{x} \\\\x=\dfrac{2 \cdot 100 \%}{8} =25 \%[/tex]
100% - 25% = 75% - the percent decrease.

Answer:
∠E = ∠A = 34°; ∠AFB = ∠DFE = 107°-34° = 73°
Step-by-step explanation:
Here's where I'd go next.
73° (∠EDA) is exterior to ΔDAC, so is the sum of remote interior angles A and C. That is, ...
∠C + ∠A = 73°
∠C = 73° -∠A = 73° -39° = 34°
Triangle CBE is given as isosceles, so its base angles C and E are congruent, both 34°.
Exterior angle CDF is the sum of remote interior angles DEF and DFE, so we have ...
107° = 34° +∠DFE
∠DFE = 107° -34° = 73°
The angle we just found (∠DFE) is a vertical angle with ∠AFB, so has the same measure.
∠AFB = 73° . . . . vertical angle with ∠DFE
_____
In summary, it looks like we have added some steps to the derivation:
4. ∠A = 34° . . . . exterior angle theorem (∠A +39° = 73°)
5. ∠E = ∠A = 34° . . . . definition of isosceles triangle
6. ∠DFE = 73° . . . . exterior angle theorem (∠E +34° = 107°)
7. ∠AFB = 73° . . . . vertical angles

Additional comment
Any sort of math problem solving has you work from what you know to what you need to know by making use of previously learned relationships between the bits of information you have. Here, you really only need to know (a) angles of a linear pair total 180°; (b) angles in a triangle total 180°; (c) angles opposite congruent sides in a triangle are congruent. Everything we claim above can be concluded using these facts. The various theorems we used are simply shortcuts that allow you to bypass intermediate steps in the problem-solving process.

A charter bus travels 225 miles in
4.5 hours. Assume the
distance traveled is directly
proportional to the time spent.
Write a direct variation equation.
A) x + 50 = y
B) y + 50x = 0
C) x= - 50 y
D) y = 50x
D because y (time spent) = 50 × x (distance travelled)
225÷4.5=50
x÷y=50

Step-by-step explanation:
which is the correct graph for the equation?
Answer:
From the given graph, we can easily determine that graph A contains the y-intercept b = 3.
Thus, option A is the correct option.
The graph of the equation is also attached below.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the function
2x+5y=15
converting the equation into the slope-intercept form
5y = -2x + 15
divide both sides by 5
y = -2/5x + 3
Thus,
The slope of the line is: m = -2/5
The y-intercept of the line: b = 3
In other words, the ordered pair (0, 3) represents the y-intercept.
From the given graph, we can easily determine that graph A contains the y-intercept b = 3.
Thus, option A is the correct option.
The graph of the equation is also attached below.

Solve the following quadratic equation by rearranging and then factorising x^2 + 7x + 19 = 9
Answer:
your lucky you did have a online lessons earlll
Step-by-step explanation:
The following are the temperatures in °C for the first 14 days of January:
-6, -2.5, 2, 2.5, -0.5, 5, 10, -3, -7, 3, -1, 7, 1, 4.5
Answer:
x = -5 & x = -2
Step-by-step explanation:
x^2 + 7x +10 = 0 you takeaway 9 as quadratic equations have to equal 0
(x+5)(x+2) = 0 you find 2 numbers that go into 10 that add to make 7 and multiply to make 10
(x+5) = 0 so x =-5 & (x+2) = 0 so x =-2
James is playing a dice game. He is rolling two 6-sided dice. To win, the two dice must sum to a
number greater than 7. What is the probability that he will win?
Answer:
9/20
Step-by-step explanation:
4+4=8, 4+5=9, 4+6=10, 5+5=10, 5+6=11, and 6+6=12 are the nine possible roll combinations that have a sum greater than 7 out of the possible 20 different combinations. This makes the probability of rolling a sum greater than 7 a nine in twenty chance.
