The perimeter of an inceles triangle is 21 meters. The length of one
sade is 3 meters longer than the length of the other two sides. Find the
length of each side
Answer:
The sides are 6, 6 and 9
Step-by-step explanation:
Isosoles triangles have two sides the same length, s
Here the third side is 3 meters longer (s + 3)
therefor the perimeter is
s + s + (s + 3) = 21
Combine like terms
3s + 3 = 21
Subtract 3 from both sides
3s = 18
Divide both sides by 3
s = 6
s + 3 = 9
The sides are 6, 6 and 9
If A is the reference angle, which side is the opposite?
AB
BC
AC
Explain your thinking.
Answer:
BC
Step-by-step explanation:
it would be BC because you are basically taking the angle and drawing an arrow to the opposite side. another trick would be choosing an answer choice without the letter in it. also you didn't put what shape so I assumed it was a triangle

Step-by-step explanation:
2x – 5x + 16 = –3(x – 6)
Answer:
0
Step-by-step explanation:
2x – 5x + 16 = –3(x – 6)
2x - 5x + 16 = -3x + 18
-3x + 16 = -3x + 18
0x = 1
x = 0
Answer:
x = ∅
Step-by-step explanation:
2x - 5x + 16 = - 3 (x - 6)
combine like terms
- 3x + 16 = - 3 (x - 6)
distribute
- 3x + 16 = - 3x + 18
subtract 3x from both sides
16 = 18
The equation is false and so x = ∅

ILL MARK BRAINIEST IF YOU CAN DO THE RIGHT!!!
Answer:
5/2
Step-by-step explanation:
We first find the equation of the line. The slope-intercept form of a line is y = mx + b, where b is the y-intercept and m is the slope. We already know the y-intercept, which is (0,5). Therefore, our current equation is:
y = mx + 5.
We use (0,5) and (1,3) to find the slope. We subtract the two y-coordinates, 5 - 3 = 2. We subtract the x-coordinates, 0 - 1 = - 1. The slope is given as rise/run, which is (y-coordinate difference)/(x-coordinate difference. Thus, the slope is 2/-1, which is just -2. Now, we put -2 in place of m:
y = -2x + 5.
The x-intercept is when the y-coordinate is equal to 0. So we substitute 0 for y:
0 = -2x + 5
-5 = -2x
x = 5/2
Determine which statements are reasonable conclusions based on the data.
Choose Yes or No for each statement.
a. The point at (19, 14) is an outlier because it is outside the main cluster of data.
b. As the number of hits increases, the number of runs scored tends to decrease.
There is a positive linear association between the number of hits and the
number of runs scored.
d. There is a non-linear association between the number of hits and the
number of runs scored.
The point at (7, 13) is an outlier because it is the only game for which the
number of runs is greater than the number of hits.
f. If the trend continues, for a game when Tyler's team gets 20 hits, the number
of runs scored will most likely be greater than 10.

If Bob mowed 14x² + 12x – 3 yards total for the entire week, how many yards
did he mow during the rest of the week?
Answer:
I am going with zero yards.
Step-by-step explanation:
If Bob mowed 14x² + 12x – 3 yards total for the entire week, how many yards
did he mow during the rest of the week?
If he mowed 14x² + 12x – 3 yards for the entire 7 days of the week. He would not have anymore days to left in the week to mow, so he mowed ZERO more yards

Answer:
vertex = (3, 1 )
Step-by-step explanation:
Given a parabola in standard form

x = 180 - 99
x = 81
Answer:
x = 81°
Step-by-step explanation:
The two angles shown add up to 180° because they are supplementary because they forma straight line. So, we can write an equation to model the situation:
x° + 99° = 180°
x = 81°

First, put the values in order from least to greatest.
2, 18, 3, 2, 9, 17, 41, 22, 25, 27, 17, 5, 4 becomes
2, 2, 3, 4, 5, 9, 17, 17, 18, 22, 25, 27, 41
The mean is the sum of all the values divided by the number of values.
2 + 2 + 3 + 4 + 5 + 9 + 17 + 17 + 18 + 22 + 25 + 27 + 41 = 192. 192/13 = 14.7692308, which rounds to 14.8
The median is the number in the middle, which is 17.
The mode is 2 AND 17, because those are the numbers that appear most often.
Range is the maximum value minus the minimum value. 41 - 2 = 39 so that is the range.
Upper quartile is the median of all the numbers to the right of 17. Median of 17, 18, 22, 25, 27, 41 is 23.5 because it is the mean of the 2 numbers in the middle.
Lower quartile is the median of all the numbers to the left of 17. Median of 2, 2, 2, 3, 4, 5, 9 is 3.5 because it is the mean of the 2 numbers in the middle.

Find the exact value of tan A in simplest radical form.
Answer:
tan A = √(3)/3[tex]tan A=\frac{\sqrt{3} }{3}[/tex]
Explanation:
tan = opposite/adjacent
tan A = BC/AC
tan A = 5/√75
tan A = 5/√(25×3)
tan A = 5/5√3
tan A = 1/√3
tan A = 1/√3 × √3/√3 (rationalizing the denominator)
tan A = √(3)/3

The image of the hexagon is missing, so i have attached it.
Answer:
∠1 = 36°
Step-by-step explanation:
From the image attached, we can see that the polygon is regular and has 10 sides.
Formula for an interior angle of a regular polygon is;
θ = 180(n - 2)/n
Where n is the number of sides of the polygon.
Thus;
θ = 180(10 - 2)/10
θ = 144°
Now, ∠1 forms a straight line with one of the interior angles of the polygon.
Thus, θ + ∠1 will be equal to 180° because sum of angle on a straight line is 180°
Thus;
144° + ∠1 = 180°
∠1 = 180° - 144°
∠1 = 36°
Ted ate 3 pieces of the pizza. what is the area of the remaining pizza if the diameter of the pizza is 18 inches?
A. 95.4 square inches
B. 381.7 square inches
C. 159.0 square inches
D. 636.2 square inches.
Answer:
C. 159.0 square inches
Step-by-step explanation:
Given that
Ted ate 3 pieces of the pizza
We need to find out the area of the remaining pizza in the case when the pizza diameter is 18 inches
Since the large circular pizza is divided into 8 equal slices
Now the radius of a pizza is
= 18 ÷ 2
= 9 inches
Now the angle subtended by each pizza is
= 360 degrees ÷ 9 inches
= 45 degrees
Now the area of the each pizza is
= [tex]\theta[/tex] ÷ 360 × πr^2
= 45 ÷ 360 × 3.14 × 9^2
= 31.7925
Now the area of the remaining pizza is
= 5 × 31.7925
= 158.9625
= 159 square inches

A car used 1/ 64 of a gallon of gas to drive 1 4of a mile. At this rate, how many miles can the car travel using 1 gallon of gas?
Answer: 16 miles
Step-by-step explanation:
The car used 1/64 gallons to travel 1/4 miles. To find out how many miles the car can travel using 1 gallon, use direct proportion:
1/64 gallons : 1/4 miles
1 gallon : x miles
Cross multiply:
1/64x = 1/4
x = 1/4 ÷ 1/64
= 1/4 * 64/1
= 16 miles
On one gallon of gas, the car can travel 16 miles.
