Answer: 9 / 20
Step-by-step explanation:
Convert both of the fractions to decimals and then sum them up.
= 2/10 = 0.2
= 25/100 = 0.25
= 0.2 + 0.25
= 0.45
The convert this figure back to fractions.
As it is 2 digits after the decimal, it is over 100 when converted.
= 45 / 100
Take it to the lowest term:
= 45 / 100 ÷ 5
= 9 / 20

Question : In the given figure , ∆ APB and ∆ AQC are equilateral triangles. Prove that PC = BQ.
~Thanks in advance ! <3
Answer:
See Below.
Step-by-step explanation:
We are given that ΔAPB and ΔAQC are equilateral triangles.
And we want to prove that PC = BQ.
Since ΔAPB and ΔAQC are equilateral triangles, this means that:
[tex]PA\cong AB\cong BP\text{ and } QA\cong AC\cong CQ[/tex]
Likewise:
[tex]\angle P\cong \angle PAB\cong \angle ABP\cong Q\cong \angle QAC\cong\angle ACQ[/tex]
Since they all measure 60°.
Note that ∠PAC is the addition of the angles ∠PAB and ∠BAC. So:
[tex]m\angle PAC=m\angle PAB+m\angle BAC[/tex]
Likewise:
[tex]m\angle QAB=m\angle QAC+m\angle BAC[/tex]
Since ∠QAC ≅ ∠PAB:
[tex]m\angle PAC=m\angle QAC+m\angle BAC[/tex]
And by substitution:
[tex]m\angle PAC=m\angle QAB[/tex]
Thus:
[tex]\angle PAC\cong \angle QAB[/tex]
Then by SAS Congruence:
[tex]\Delta PAC\cong \Delta BAQ[/tex]
And by CPCTC:
[tex]PC\cong BQ[/tex]
Answer:
Step-by-step explanation:
To prove PC = BQ, we need to prove triangle APC and ABQ are congruent.
AP = AB as they are part of equilateral triangle APB
AC = AQ as they are part of equilateral triangle AQC
Angle PAC = Angle PAB + Angle BAC = 60 + Angle BAC
Angle BAQ = Angle QAC + Angle BAC = 60 + Angle BAC = Angle PAC
By SAS, triangle APC and ABQ are congruent and therefore
PC = BQ
The dot plot shows the number of free homework passes received by students ima. class Each dot represents 1 student
What percent of the student did not receive a free homework pass??
a 8%
b 16%
c 32%
d 68%
Answer:
C. 32%
Step-by-step explanation:
To find the denominator here, we have to count up how many dots/students there are total. Then our numerator is how many students are in the zero column.
That gives us 8/25 = 0.32. Multiply by 100 for the percentage = 32%

Jordan is 12 years older than Anna. The
sum of their ages is 50. Find the age of
each person.
Answer:
Jordan age = 31 yearsAnna age = 19 yearsStep-by-step explanation:
let Jordan age be X & Anna age be Y
so,
Jordan is 12 years older than Anna.
x = y + 12 ......... (1)
The sum of their ages is 50.
x + y = 50 ........ (2)
putting value of x from (1) into (2)
x + y = 50
(y + 12) + y = 50
2y + 12 = 50
2y = 50 - 12
2y = 38
y = 38÷2
y = 19
putting value of y in (2)
x + y = 50
x + 19 = 50
x = 50 - 19
x = 31
so,
Jordan age = 31 years
Anna age = 19 years

If sintheta = cos theta then the value of acute angle is
Answer:
45 degrees
Step-by-step explanation:
Here, we want to get the value of the acute angle
From the question, we have it that the sin of the acute angle equals its cosine
Recall;
cos A = sin (90-A)
Hence, if A is 45, then Cos A and Sine A will be the same
This means the value of theta which is the acute angle is 45 degrees

a cylinder has a height of 40 ft and a radius of 10 ft. can its volume be 10 ft? why or why not?
Answer:
Volume of cylinder = 12,560 feet³
Step-by-step explanation:
Given:
Height of cylinder = 40 ft
Radius of cylinder = 10 ft
Find:
Can its volume be 10 ft ?
Computation:
Volume of cylinder = πr²h
Volume of cylinder = (22/7)(10)²(40)
Volume of cylinder = (3.14)(10)²(40)
Volume of cylinder = (3.14)(100)(40)
Volume of cylinder = 12,560 feet³
Volume of this cylinder never be 10 feet

and how -(11 x)/4 - 5 = 0
1/4 (7 x - 12) = 1/2 (9 x + 4)
hope this helps
Answer:
X = 11/20
Step-by-step explanation:
7/4x-3=2+9/2x
We move all terms to the left:
7/4x-3-(2+9/2x)=0
Domain of the equation: 4x!=0
x!=0/4
x!=0
x∈R
Domain of the equation: 2x)!=0
x!=0/1
x!=0
x∈R
We add all the numbers together, and all the variables
7/4x-(9/2x+2)-3=0
We get rid of parentheses
7/4x-9/2x-2-3=0
We calculate fractions
14x/8x^2+(-36x)/8x^2-2-3=0
We add all the numbers together, and all the variables
14x/8x^2+(-36x)/8x^2-5=0
We multiply all the terms by the denominator
14x+(-36x)-5*8x^2=0
Wy multiply elements
-40x^2+14x+(-36x)=0
We get rid of parentheses
-40x^2+14x-36x=0
We add all the numbers together, and all the variables
-40x^2-22x=0
a = -40; b = -22; c = 0;
Δ = b2-4ac
Δ = -222-4·(-40)·0
Δ = 484
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
x1=−b−Δ√2ax2=−b+Δ√2a
Δ−−√=484−−−√=22
x1=−b−Δ√2a=−(−22)−222∗−40=0−80=0
x2=−b+Δ√2a=−(−22)+222∗−40=44−80=−11/20

Find the measure of XY. Assume that segments that appear to be tangent are tangent. Round your final answer to the nearest tenth, if necessary.
Answer:
Solution given:
7x-29=2x+16[length from the circumference of circle is equal to same point]
7x-2x=16+29
5x=45
x=45/5=9
now.
XY=2×9+16=18+16=34 is your answer
The measure of tangent XY is 34.
What is tangent on a circle?If two tangents are drawn to a circle from an external point, then they are equal in length.
This property is often used in geometry problems to find the length of a tangent segment or to solve for an unknown variable.
We have,
The two tangents in a circle are equal.
So,
2x + 16 = 7x - 29
Solve for x.
2x + 16 = 7x - 29
7x - 2x = 16 + 29
5x = 45
x = 9
Now,
XY
= 2x + 16
= 2 x 9 + 16
= 18 + 16
= 34
Thus,
The measure of XY is 34.

Neil is going to a bookstore 45 miles away. The bridge was closed on the way back, so
he had to take an alternate route and had to drive 15 mph slower, which make the trip
back take 7 minutes longer. How fast was he going on the way to the bookstore?
Answer:
35 mph
Step-by-step explanation:
As you might have learned in your physics class, the average speed of a car in mph is 50. You should write this down on some paper.
After writing it down, we need to look at what the problem is asking us, so we don't get confused. " How fast was he going on the way to the bookstore?"
This means that we need to calculate his mph speed on the way to the bookstore by subtracting something.
50 mph=Average
Alternate Route= -15
After you have written THAT down in your notes, you need to ask yourself,
"What is 50-15?"
Calculating 50-15 will make the "15 mph slower" show up and calculating that with the average will get you your answer.
50-15 is 35
