Q:-If the perimeter of an isosceles triangle is 83 cm. and its base is 23 cm. Find the measure of its equal sides.
Answer:- As we know that Perimeter is the sum of all sides.
Let the both side be x83 = 23 + (x + x)83 - 23 = 2x60 = 2x30 = xOther two sides are 30 cm.

198 woman to 110 men in the simplest form
Answer:
1 4/5
Step-by-step explanation:
198 woman to 110 is basically a ratio, so we should put it like this: 198:110
Now, a ratio that needs to be simplified is basically a fraction, so: 198/110
Now we divide the fraction.
First, find the GCF of both numbers.
The GCF of 198 and 110 are both 22.
Now we divide, and we get 9/5, and we turn it into a mixed number, 1 4/5.

when time in hours (t) increases, how does distance in km (d) change?
Question seems incomplete but will be explained with assumptions
Answer and explanation:
If for example, a car travels 30 km per hour, then it would travel 60km in 2 hours and 90km in 3 hours and so on
We can apply the formula for distance as such:
Distance(d)= Speed(s) × time(t)
d=st
Where d is distance travelled say 60km
S is speed= 30km/hr
Time = 2 hrs
Also to calculate speed when distance and time is given, we can make speed the subject of the formula:
s=d/t
To calculate time when distance and speed are given, we can make time the subject of the formula:
t=d/s

What is the measure of angle KLM
Answer:
In triangle KLM, the measure of angle K is 119 degrees, KL=23, and KM=20.
The measurement of the angle KLM is 64°.
What is an angle?An angle is a geometrical shape that is formed by two rays or lines, called the sides or arms of the angle, that share a common endpoint, called the vertex of the angle.
Given is a figure, we need to find the measurement of ∠KLM,
Here,
∠KLM + ∠KLJ = 180° [linear pair]
20x+4 + ∠KLJ = 180°
∠KLJ = 176-20x
Consider the triangle, KLJ,
∠KLJ + ∠KJL + ∠JKL = 180° [sum of the interior angles of a Δ)
8x+18+6x+4+176-20x = 180°
-6x = -18
x = 3
So, ∠KLM = 20(3)+4 = 64°
Hence, the measurement of the angle KLM is 64°.

A. HL
B. SSA
C. SAS
D. None, not congruent
SAS is the postulate that establishes the congruence of these two triangles.
What is meant by triangle?The three vertices of a triangle make it a three-sided polygon. The angles of the triangle are formed by the three sides' end-to-end connections at a point. 180 degrees is the sum of the triangle's three angles. According to the Angle-Side-Angle Postulate (ASA), if two angles from one triangle and its included side are congruent with two angles from another triangle and its included side, then the two triangles are congruent. Three sides and three vertices make up a triangle, which is a polygon. There is a 180 degree angle created inside the triangle. In other words, a triangle's internal angles add up to 180 degrees.To learn more about triangle, refer to:

The cost of tuition at a 2 year school is $14,000 per academic year. Todd is eligible for $6,500 in financial aid to cover tuition each year. He will save money for one year to cover the remaining cost of tuition for his two years of school.
What is the minimum amount of money he needs to save each month?
$540
$625
$675
$1,250
Answer:
$625
Step-by-step explanation:
If Todd has to pay $14,000 in tuition for his school each year and uses $6,500 in financial aid each year all for 2 years, the money he needs to save can be modeled by:
2(-$14000 + $6500) + 2(12x) = 0.
x is the minimum amount of money he needs to save in order to cover this expense without debt.
Thus 2(-$14000 + $6500) + 2(12x) = 0 →
2(-$7500) + 24x = 0 → -$15000 + 24x = 0 →
24x = $15000 → x = $625
Answer:
$625
Step-by-step explanation:
If Todd has to pay $14,000 in tuition for his school each year and uses $6,500 in financial aid each year all for 2 years, the money he needs to save can be modeled by:

Answer:
C. [tex]30\sqrt{2}[/tex]
I hope this helps!
The simplified form of expression 3 times the square root of 200 is 30√2 ( thirty times square root 2 ) .
To simplify the expression 3 times the square root of 200, we can break it down into smaller components .
First, let's simplify the square root of 200 :
√ 200 = √ ( 100 × 2 ) = √ 100 × √ 2 = 10√2
Now, we substitute this simplified value back into the original expression :
3 × √ 200 = 3 × ( 10√ 2 ) = 30√ 2
Therefore, the simplified form of 3 times the square root of 200 is 30√2 .

Four cards will be dealt off the top of a well-shuffled deck. There are two options. (i) To win $10 if the first card is club and the second is a diamond and the third is a heart and the fourth is a spade. (ii) To win $10 if the four cards are of four different suits. Compute the probability of winning $10 for each case. Which option is better
Answer:
0.0043957 ; 0.105498 ; 2nd option is better
Step-by-step explanation:
Option 1:
First card :P(club) = 13/52
Second card: P(diamond) = 13/51
Third card : P(heart) = 13 / 50
Fourth card: P(spade) = 13/49
Hence,
P(club, diamond, heart, spade) = (13/52) * (13/51) * (13/50) * (13/49) = 0.0043957
Probability of winning $10 = 0.0043957
2nd option:
P(card of different suit) [order of arrangement does not matter]
(13C1 * 13C1 * 13C1 * 13C1) / 52C4
= 28561 / 270725
= 0.105498
Probability of winning $10 = 0.105498
Because the probability of winning for the second option is higher than for the first option, then the second option is better.

Step-by-step explanation:
that's what my teacher said.
6x + 2y = 10 and -4x=-8 system of equations has the same solution as the system of equations 6x + 2y = 10 and 8x + 4y = 12
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given system of equations are
6x+2y=10..(1)
2y=10-6x...(2)
We need to find system of equation which having same solutions as above.
From equation (2)
y=5-3x
Now substitute y value in equation 1.
8x+4(5-3x)=12
8x+20-12x=12
-4x=12-20
-4x=-8
Hence, 6x + 2y = 10 and -4x=-8 system of equations has the same solution as the system of equations 6x + 2y = 10 and 8x + 4y = 12
