Answer:
a) the cost of one medium drink be $3.80
b) the cost of a large popcorn be $6.25
Step-by-step explanation:
Let the cost of one medium drink be $x and the cost of a large popcorn be $y
According to question, A couple bought 2 medium drinks and a large popcorn for $13.85.
2x + y = 13.85 ..............(1)
A family bought 3 medium drinks and 2 large popcorn for a total of $23.90
3x + 2y = 23.90 ..............(2)
Using Elimination method to solve the system of equation. Multiply equation (1) by 2 , we get,
4x + 2y = 27.70 ..............(3)
Now, subtract equation (2) from (3), we get,
4x + 2y-(3x + 2y) = 27.70 - 23.90
4x + 2y-3x - 2y = 3.80
4x -3x = 3.80
x = 3.80
Substitute, x = 3.8 in (1) ,
2(3.80) + y = 13.85
7.60 +y = 13.85
y = 6.25
Therefore, the cost of one medium drink be $3.80
and the cost of a large popcorn be $6.25

The graph shows the results of tossing two coins 20 times. The two sides of the coin show heads (H) and tails (T). Based on the results, what is the probability that both coins will show heads the next time the coins are tossed? 17 20 Two Coin Toss 8 CON Frequency ONWAY 3 20 HT TH HH IT 3 10
Answers
You forgot the picture
The probability that both coins will show heads the next time the coins are tossed is 3/20.
What is probability?Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
From the graph, Total number of outcomes= 7+6+4+3=20
Outcomes for both head =6
Then, P(HH)= 6/20
=3/10
Hence, probability that both coins will show heads is 3/20.

An eagle 311 feet in the air spots its prey on the ground. The angle of depression to its prey is 15°. What is the distance between the eagle and its prey? Round to the nearest foot.
Answers
Sorry if that’s incorrect, but here’s the explanation in case you need it:
The tangent of a triangle is the opposite leg over the adjacent leg. 311 is the opposite leg, and X would be the adjacent leg. So 311 divided by x is equal to tan 15. If we rearrange this to be equal to X, X equals 311 divided by tan 15. Tan 15 is equal to 0.2679, so 311/0.2679 = 1,160.6. That amount rounds up to 1,161, giving you the answer of 1,161 feet.

cos²x - sin²x = 0,66
Answers
x = 24.35°
Step-by-step explanation:
Recall that
cos²x - sin²x = cos 2x
which means that
cos 2x = 0.66 ---> 2x = cos^-1 (0.66) = 48.7°
or x = 24.35°
Answer:
x = 24.35, 155.65, 204.35, 335.65 degrees ( for 0 < x < 360 degrees).
Step-by-step explanation:
cos²x - sin²x = 0.66
cos^2 x = 1 - sin^2 x so
1 - sin^2 x - sin^2 x = 0.66
1 - 2sin^2 x = 0.66
2sin^2 x = 1 - 0.66
sin^2x = 0.34/2 = 0.17
sin x = +/- √0.17
= +/- 0.41231
x = 24.35 degrees ( in first quadrant)
and 180 + 24.35 = 204.35 degrees in third quadrant.

Answers
Answer: c=35
D=90
E=55
Step-by-step explanation:
Since d is a right angle it is 90. Take 90 and subtract it from 180 to get 90.Set them equal to 90 so 3x+11+5x+15=90
Simplify
8x+26=90
8x=64
X=8
Now take x and plug it in for each equation
3(8)+11=35
5(8)+15=55
So measured of c is 35
Measure of e is 55
And d is 90

A wise man once said, "500 reduced by 4 times my age is 188." What is his age?
Answers
Answer:
125
Step-by-step explanation:
Answer:
He Is 78 Years Old.
Step-by-step explanation:
a = age
Solve for a in 500 - 4a = 188.
Simplify 500−4a=188.
500−4a=188
500+−4a=188
−4a+500=188
Subtract 500 from both sides.
−4a+500−500=188−500
-4a = -312
Divide both sides by -4.
[tex]\frac{-4a}{-4} =\frac{-312}{-4}[/tex]
a = 78
Answer:
He Is 78 Years Old.

Suppose you brought 8 oranges and 1 grapefruit for a total price of $4.60. Later that day, you brought 6 oranges and 3 grapefruits for a total price of $4.80.What's the price of each type of fruit.
Answers
Answer:
assuming the prices did not change during the day,
8o+g=460
6o+3g=480
18o=900
o=50
g=60
so, oranges cost $0.50, grapefruit cost $0.60
Step-by-step explanation:
do good !
Answer:
oranges $0.5 grapefruit 0.6
Step-by-step explanation:
o = oranges
g= grapefruit
8o +1 g = 4.60
6o+3g= 4.80
Multiply the first by -3
-24o -3g = -13.80
6o +3g = 4.80
ADD BOTH (3g will be cancelled)
-18o = -9.00
o = 9/18 = 0.5
8(0.5) +1g= 4.60
4.00 +g = 4.60
g = 0.60
