Answer:
10. Let m<Y = y.
Then,
m<Y + m<X +m<Z = 180 [ Sum of angles of triangle is 180 degrees]
or, y + (6x-23) + (4x + 9) = 180
or, y + 10x -14 = 180
or, y = 194 - 10x
or, m<Y = 194 - 10x
12. Solution,
a. m<1 = 60 degrees [Each angles of equilateral triangle is equal to 60 degrees]
b. In triangle WYZ,
m<Z + m<ZWY + m<ZYW =180 [Sum of angles of triangle is 180]
or, 138 + m<ZWY +m<ZWY =180 [Base angles of isosceles triangle are equal, i.e. m<ZYW = m <ZWY]
or, 2 (m<ZWY) = 180 -138 = 42
or, m<ZWY = 21 = m<ZYW
or, m<3 = 21 = m<5
c. Solution,
m<XWY = m<2 + m<3 [Addition axiom]
or, 60 = m<2 + 21 [Each angle of equilateral triangle is 60]
or, m<2 = 39
d. Solution,
m<4 + m<5 =60 [<XYW = 60 ]
or, m<4 + 21 = 60
or, m<4 = 39

Answer:
50 degrees
Step-by-step explanation:
A triangle's angles added up together is 180 degrees. We already know that the right angle is 90 degrees, and the other angle is 40 degrees. To find the missing angle, we need to add 90+40 to get 130 degrees, and subtract the sum from 180 degrees to get our missing angle of 50 degrees.

Answer:
$16.50 for two ice cream cones!
Step-by-step explanation:
Its very simple ^w^
$8.25 + $8.25
add both of the 0.25s to get 0.50
Then add 8 + 8 to get 16!
And then add 16 and 0.50 together and get 16.50

Two pools are being filled with water. To start, the first pool had 1600 liters of water and the second pool had 1204 liters of
water. Water is being added to the first pool at a rate of 24 liters per minute. Water is being added to the second pool at a rate
of 35 liters per minute.
Let x be the number of minutes water has been added.
Answer:
Step-by-step explanation:
Given
the first pool -600 liters
The second pool -1204 liters
the first pool =24 liters per minute. the second pool = 35 liters per minute.
So
total time taken of water in first pool=600/24
=25 mintue
Total time taken of water in second pool=1024/35
=29.27 minute

Enter a range of values for x please help me
Answer:
-5 < x < 9
Step-by-step explanation:
By Hinge theorem,
"If two sides of a triangle are congruent to the two sides of another triangle, and the included angle of one triangle is larger than the included angle of the second, then the 3rd side of triangle one will be larger than the third side of the second"
23 > 21
Therefore, 42° > (3x + 15)°
42° - 15° > 3x
27 > 3x
9 > x
And (3x + 15) > 0
3x > -15
x > -5
Therefore, range for x will be,
-5 < x < 9

If MB = 6x-9, and AM = 27, find x.
Answer:
x=11
Step-by-step explanation:
M is the midpoint this means that we can set AM and BM equal to eachother, once this is done we can solve for x
9x-6=6x+27 (set equal to eachother)
9x=6x+33 (add 6)
3x=33 (subtract 6x)
x=11 (divide by 3)

The American Heart Association is about to conduct an anti-smoking campaign and wants to know the fraction of Americans over 40 who smoke.
a. Suppose a sample of 1089 Americans over 40 is drawn. Of these people, 806 don't smoke. Using the data, estimate the proportion of Americans over 40 who smoke. Enter your answer as a fraction or a decimal number rounded to three decimal places.
b. Suppose a sample of 861 Americans over 47 is drawn. Of these people, 577 don't smoke. Using the data, construct the 80% confidence interval for the population proportion of Americans over 47 who smoke. Round your answers to three decimal places.
Answer:
0.259 or 25% or 1/4
and i couldnt figure out b sorry
Step-by-step explanation:
a) The proportion of Americans over 40 who smoke will be 7.075.
b) The population proportion of Americans over 47 who smoke will be 227.2.
What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
a) A sample of 1089 Americans over 40 is drawn.
And, Of these people, 806 don't smoke.
b) A sample of 861 Americans over 47 is drawn.
And, Of these people, 577 don't smoke.
Here,
a) A sample of 1089 Americans over 40 is drawn.
And, Of these people, 806 don't smoke.
So, The proportion of Americans over 40 who smoke = 1089 - 806 / 40
= 283 / 40
= 7.075
b) A sample of 861 Americans over 47 is drawn.
And, Of these people, 577 don't smoke.
So, the 80% confidence interval for the population proportion of Americans over 47 who smoke = 80% of (861 - 577)
= 80% × 284
= 80/100 × 284
= 227.2
