Use a ruler and a protractor to determine
whether or not it is possible to draw a
triangle with a 75° angle, a 115° angle, and a
side of 4 inches between the two angles. If
so, draw the triangle. If not, explain why.
Answer:
It is not possible.
Step-by-step explanation:
The triangle is impossible to create because of the Triangle Angle Sum Therom, which states that all 3 angles in a triangle must = 180 degrees. As they haven given us 75 degrees, and 115 degrees 75+115=190 Which is more then 180, Hence it is not possible.

Jody is buying a scrapbook and sheets of designer paper. She has
$40 and needs at least $18.25 to buy the scrapbook. Each sheet of
paper costs $0.34.
How many sheets of paper can she buy?
Answer:
Step-by-step explanation:
$40 - $18.25 = $21.75
she has $21.75 to buy the paper with
21.75 divided by 0.34 is 63.971...
this means she only has enough money to buy 63 sheets of paper

What is the probability of picking a 5 and then picking a 5?
Write your answer as a fraction or whole number.
Answer:1/169 i think
Step-by-step explanation:
Because you have to get a 5 twice in a row your first probability for one would be 4/52 or 1/13 but because you have to do it twice in a row you multiply the odds together 1/13*1/13=1/169

Step-by-step explanation:
OK so AC is 18, since both of those sections are 9, and 9+9=18.
But for AG im kind of stuck. At first I thought it was 11 but then just by looking at it you can see that they aren't the same length(I mean AG and GC) so I don't know about that one.
heres what I THINK it could be
GF and GD COULD BE the same length, considering that this is a 3d shape.
So, since AGF is a right triangle, we can use pythagorem. theorem.
7^2+9^2=x^2
49+81=x^2
130=x^2
x==11.40
MAYBE AG=11.40.

How many pounds is 3/12 and 1/12?
Answer:
Step-by-step explanation:
Remark
This is just a matter of adding 2 fractions and reducing the result
Givens
f1 = 3/12
f2 = 1/12
Equation
Answer = f1 + f2
Solution
answer = 3/12 + 1/12
The denominators are the same. The answer will have the same denominator
Answer = (3 + 1)/12
Answer = 4 / 12
The answer has a common factor in both the top and bottom of the fraction (4 is the common factor).
Therefore divide the top and bottom by 4
Answer = 4/4 // 12/4
Answer = 1 / 3
please help me find DE
You can split up the length of AE into the lengths of the line segments connecting adjacent points:
AE = AB + BC + CD + DE
Plug in everything you know and solve for DE :
9 = (2 1/2) + (4 1/3) + (1 2/3) + DE
Rewrite the mixed numbers as improper fractions with a common denominator.
2 1/2 = 4/2 + 1/2 = 5/2 = 15/6
4 1/3 = 12/3 + 1/3 = 13/3 = 26/6
1 2/3 = 3/3 + 2/3 = 5/3 = 10/6
9 = 54/6
So we have
54/6 = 15/6 + 26/6 + 10/6 + DE
⇒ DE = (54 - 15 - 26 - 10)/6 = 3/6 = 1/2

XY
delta math
The length XY of the circle X is the radius of the circle
The length of XY is 9 units
How to determine the length of XY?The parameters are given as:
Length of arc, YZ = 5πCentral angle, YXZ = 100°The length of arc is calculated using:
L = Ф/360 * 2πr
Where:
L = YZ = 5πФ = YXZ = 100°Radius, r = XYSo, we have:
5π = 100/360 * 2πr
Evaluate the quotient
5π = 5/9 * πr
Divide both sides by 5π
1 = 1/9 * r
Multiply both sides by 9
r = 9
This means that
XY = r = 9
Hence, the length of XY is 9 units
