geometry work help find the value of x
Answers
Answer:
110⁰!!
Step-by-step explanation:
so this is an isosceles triangle! the base angles are always equal to each other. since 35 is a vertical angle, the base angle vertical to that would be 35. and since base angles ALWAYS equal each other, they would both be 35.
35+35=70, 70 is the base angles added up
180-70=110

Hope this helps and have a great day :)Find the y-intercept of a line that passes through the point (-5,-6) and has a slope of 2.
Answers
Answer:
The y intercept is 4
Step-by-step explanation:
Given:
-Given point: (-5,-6)
-Slope of 2
1) Put the equation into point-slope form y - y1 = m(x - x1)
With the given, we can plug it all in using this formula!
-y1 = -6
-x1 = -5
m = 2
(you would change these negative numbers into positives because the equation shows them being subtracted! remember that two negatives make one positive!)
y+6= 2(x+5)
2) Simplify
y+6= 2(x+5)
y+6=2x+10
y=2x+4
With y=2x+4, set x to 0 because the y intercept is where x is equal to 0 and you get 4!

Find x and the lengths of sides JM, MN, and JN. Triangle JMN is an isosceles triangle with side JM ≅ side MN. JM = 2x - 5, MN = 3x -9, and JN = x - 2.
Answers
Answer:
x = 4
JM ≅ MN = 3
JN = 2
Step-by-step explanation:
In an isosceles triangle, two of the sides are equal. Given the lengths of sides of triangle JMN as JM, MN, and JN where JM ≅ MN
Given
JM = 2x - 5
MN = 3x -9, and
JN = x - 2.
Since JM≅ MN then;
2x - 5 = 3x-9
Collect like terms;
2x-3x = -9+5
-x = -4
multiply both sides ny -1;
-(-x) = -(-4)
x = 4
For side JM;
JM = 2x-5
JM = 2(4)-5
JM = 8-5
JM = 3
Since JM ≅ side MN, hence;
MN = 3
For side JN;
JN = x-2
JN = 4-2
JN = 2

Histogram attached
Answer and explanation:
To find the center of the distribution, we find the mean of the distribution.
Mean= sum of all values/number of values
To calculate the mean of the distribution using the histogram(attached) with given frequencies, we find the mid point of each class and multiply by its frequency to get the sum of the values(estimated) and then divide by the number of values(sum of the frequencies of the classes)
midpoint of 50-60=50+60/2=55
midpoint of 70-80=150/2= 75
midpoint of 80-90=170/2=85
midpoint of 90-100=190/2=95
midpoint of 100-110=210/2=105
Midpoint of 110-120=230/2=115
Midpoint of 120-130=250/2=125
Midpoint of 130-140=270/2=135
Midpoint of 140-150=290/2=145
Midpoint of 150-160=310/2=155
Sum of the values= 55*frequency= 55*3+75* 2+85*1+95*7+105*17+115*29+125*10+
135*2+145*3+155*3
Sum of all values =8605
Number of values= 3+2+1+7+17+29+10+2+3+3=77
Mean= 8605/77= 111.753
Therefore the center of the distribution is between 110 and 120 calories.

Answers
Answer:
Given:
A plane ticket to Barcelona costs £175 the price decreases by 6%
To find:
The new price of the plane ticket
Solution:
The ticket to Barcelona costs £ 175
The price decreases by 6%
⇒ 6% = 6/100 = 3/50
The new price of the plane ticket is decreased by the amount,
= £ 175 × 3/50
= £ 10.5
Therefore, the new price of the plane ticket is given by,
= £ 175 - £ 10.5
= £ 164.5

Answers
Answer:
Add a colon to the end of the statement
Step-by-step explanation:
Given
x = 1
while(x < 26)
print(x)
x = x + 1
Required
Spot and fix the error
Every lines of the given code segment is correct except the second line.
The syntax of a while loop is:
while(condition):
Comparing while(condition): to while(x < 26),
we'll see that while(x < 26) has a missing colon.
So, the error in the program is a missing colon and the solution is (option a) adding a colon to the end of the while statement
So, the correct code segment is:
x = 1
while(x < 26):
print(x)
x = x + 1

8.25% of 36 is 2.97
36+2.97= 38.97
Answer:
$38.97
Step-by-step explanation:
100% - 10% = 90% = 0.9
$40 × 0.9 = $36

b. y - 6 = -3(x + 1)
c. y=-3x + 3
d. 3x+y=3
Answers
Answer:
B
Step-by-step explanation:
point slope uses the form y - y1 = m(x - x1)
m stand for slope. in this case it is -3
x1 is -1 and y1 is 6
when you plug it in, you get
y - 6 = -3(x - [-1])
which simplifies to your final answer: y - 6 = -3(x + 1)

Megan bought 2 1/4 pounds of bananas for 0.80 per pound and 1 1/2 pounds of strawberries for 1.10 per pound how much more did Megan spend on bananas than on strawberries
Answers
Answer:Megan spent 0.15 pounds more on bananas than strawberries
Step-by-step explanation:
Step 1
Cost of bananas = 2 1/4 pounds of bananas for 0.80 per pound
2 1/4 x 0.80 = 1.8 pounds
Cost of strawberry= 1 1/2 pounds of strawberries for 1.10 per pounds
1 1/2 x 1.10 = 1.65.
Step 2 how much more means the difference between the cost of bananas and strawberry .
Therefore, we have Cost of bananas - cost of strawberries
1.80 pounds - 1.65 pounds=0.15
Megan spent 0.15 pounds more on bananas than strawberries
