On a softball field, home plate is 43 feet from the pitcher's mound. A ball is hit at an angle of 27° east of the pitcher's mound. The ball travels 162 feet before it is caught by an outfielder. A triangle is drawn on a baseball field. A point is at home plate, another point is at the pitcher apostrophe s mound, and another point is at an outfielder. The distance from home plate to the pitcher is 43 feet. The distance from home plate to the outfielder is 162 feet. The angle between the 2 sides is 27 degrees. Law of cosines: How far must the outfielder throw the ball to return it to the pitcher? Round to the nearest foot. 112 feet 125 feet 145 feet 156 feet
Answer:
c = 125 f
Step-by-step explanation:
Let´s call points A ( home plate ) B (pitcher´s place ) and C ( outfielder place)
these three points form a triangle in which according to cosine law, one side of a triangle c can be calculated by the equation:
c² = a² + b² - 2a*b*cos∡a,b
a and b are the other sides of the triangle and ∡a,b is the angle between sides a and b
All distances are in feet then the distance between outfielder and pitcher (c) is in feet:
c² = (43)² + ( 162)² - 2*(43)*(162)*cos 27° cos 27° = 0,891
c² = 1849 + 26244 - 12413,4
c² = 15679,6
c = √15679,6
c = 125 f

Answer:
Yes, 4 is the constant of proportionality
Step-by-step explanation:
The constant of proportionality here is the value you multiply x by to get y. if you divide 12/3, 24/6, 36/9, 60/15, the answer to all of those is 4. Because the multiplier is the same for each one they are all proportional.

Answer:
Step-by-step explanation:
1. Eggs are sold at a price of P 105.00 per dozen.
Rate = [tex]\frac{1}{105}[/tex]
2. The carpentry job can be done by 3 carpenters in 4 days.
Rate at which each carpenter works = [tex]\frac{4}{3}[/tex] = 1[tex]\frac{1}{3}[/tex] days
This shows that each carpenter worked for an average of 1.3333 days to complete the job.
3. Five tickets are sold at P 600.00
The price for one ticket = [tex]\frac{600}{5}[/tex]
= 120
One ticket is sold for P 120.00.
4. The dollar's rate is P 52.00.
This implies that;
1 dollar = P 52.00
dollar rate = [tex]\frac{1}{52}[/tex]
5. The ratio of water to milk in the recipe is 1 to 4.
This implies that to 1 measure of water, 4 measures of milk is used in the recipe.

Bonnie's favorite game at the arcade is Can Em Down. In the game, players earn 7 points for each can they knock down. Bonnie earned 84 points in her best game. Let c represent how many cans Bonnie knocked down. Which equation models the problem?
Answer:
c = (total points earned in best game / points per can knocked down)
c = 12
Step-by-step explanation:
Given that :
Points earned per knockdown = 7
Total points earned in best game = 84
Number of cans knocked down, c
c = (total points earned in best game / points per can knocked down)
c = 84/ 7
c = 12

-3 represents the distance from a stage to the floor below. 3 represents the distance from the stage to the top of a bookcase. What dose zero represent in this situation?
Answer:
the distance from the floor below to the top of the bookcase
Step-by-step explanation:
From the question we are given the following
distance from a stage to the floor below = -3
distance from the stage to the top of a bookcase = 3
The distance from the floor below to the top of the bookcase = distance from a stage to the floor below + distance from the stage to the top of a bookcase
The distance from the floor below to the top of the bookcase = -3 + 3
The distance from the floor below to the top of the bookcase = 0
Hence zero represents the distance from the floor below to the top of the bookcase

A company offers premium cable for 39.95 per month plus a one time setup fee. The total cost of 6 months of service is 264.70. Write and solve a linear equation to find the total cost for 2 years of service
Answer:
Total cost = 983.8
Step-by-step explanation:
Monthly charge = 39.95
One time set up fee = x
Number of months = y
Total cost = x + 39.95y
The total cost of 6 months of service is 264.70.
264.70 = x + 39.95(6)
264.70 = x + 239.7
264.70 - 239.7 = x
x = 25
Total cost = 25 + 39.95y
Write and solve a linear equation to find the total cost for 2 years of service
2 years = 24 months
Total cost = 25 + 39.95y
= 25 + 39.95(24)
= 25 + 958.8
= 983.8
Total cost = 983.8

Step-by-step explanation:
write the equation of each line in slope-intercept form slope=4 y-intercept=-5
Answer:
Y=4X-5
Step-by-step explanation:
The Slope is a positive 4 so you will already have the equation Y=4X and the y-intercept is the Y when X is at the origin. Since the y-intercept is negative you have to subtract from the slope instead of adding. Then you get Y=4X-5.

Gail has $5,500 that she wants to put in a new savings account. She is
considering two banks that are very similar. One difference she notices
are the interest rates:
• Neighborhood Bank - 0.65% interest, compounded weekly
Beautiful Day Bank - 0.65% interest, compounded daily
.
Based on interest, which bank would you suggest Gail pick if she plans to
have her money in the account for 15 years?
Answer: Neighborhood Bank - 0.65% interest, compounded weekly
Step-by-step explanation:
The bank she would suggest Gail pick if she plans to have her money in the account for 15 years is Neighborhood Bank - 0.65% interest, compounded weekly.
How to find the compound interest?If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:
[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]
Given that Gail has $5,500 that she wants to put in a new savings account.
Neighborhood Bank - 0.65% interest, compounded weekly
Beautiful Day Bank - 0.65% interest, compounded daily
Thus, $5,500 x 0.65% = $35.75
$35.75 a day times 360 days = $12870
$12870 times 20 = $257,400.
$257,400 times 20 = $514800 (16.2mil)
Hence, The bank she would suggest Gail pick if she plans to have her money in the account for 15 years is Neighborhood Bank - 0.65% interest, compounded weekly.

m∠1 = m∠6 =
m∠2 = m∠7 =
m∠3 = m∠8 =
m∠4 = m∠9 =
Answer:
See below
Step-by-step explanation:
Kites have perpendicular diagonals, two pairs of congruent angles and sides.
Angles 1, 2, 3, 4 are all right angles∠6 and 37 are congruent, ∠5 and 43 are congruent, ∠7 and ∠9 congruent, ∠8 and ∠10 are congruentRequired measures:
m∠1 = 90 ° m∠6 = 37°m∠2 = 90 ° m∠7 = 90° - 37° = 53° m∠3 = 90 ° m∠8 = 90° - 43° = 47 ° m∠4 = 90 ° m∠9 = 53°m∠5 = 43 ° m∠10 = 47 °The angles are m∠1 =m∠2 =m∠3 =m∠4 = 90 degrees.
m∠9=m∠7 =m∠8= m∠10 = 53 degrees.
m∠5 = m∠6 =37 degrees
Let us find the angles.
m∠1 , m∠2, m∠3 and m∠4 are right angles.
m∠1 =m∠2 =m∠3 =m∠4 = 90 degrees.
Now let us find m∠9.
By angle sum property, the sum of three angles is 180 degrees.
m∠1 + 37 + m∠9 =180
37+90+m∠9=180
127+m∠9=180
m∠9=180-127
m∠9=53
m∠9=m∠7 = 53 degrees.
Now let us find m∠6.
53+90+m∠6=180
143+m∠6=180
m∠6=37 degrees.
m∠5 = 37 degrees as it is congruent to m∠6.
Now let us find m∠8.
m∠8 + 90+ 37=180
m∠8 +127=180
m∠8 =53 degrees.
m∠10 = 53 degrees.
