Answer:
$0.60
Step-by-step explanation:
Given that:
The ratio of number of cookies to the cost of cookies as:
Number of cookies : Cost of cookies = 15 : 9
It means, we get 15[tex]x[/tex] number of cookies when we pay $9[tex]x[/tex].
To find:
An equivalent ratio to represent the cost of 1 cookie.
Solution:
Here, we have to find nothing but the unit price or the price of 1 cookie.
This can simply be done by dividing the total cost of cookies with the total number of cookies.
Total cost of 15[tex]x[/tex] cookies is given as $9[tex]x[/tex]
Using unitary method:
Let us divide both the sides with 15[tex]x[/tex], we get:
Total cost of [tex]\frac{15x}{15x}[/tex] cookies is given as [tex]\frac{\$9x}{15x}[/tex]
Total cost of 1 cookie is given as $0.60
I need help please!!!!!!!
Answer:
75°
Step-by-step explanation:
We can assume that the angle shown and an angle that measures 15° makes a complementary angle. A complementary angles is when two angles add up to be 90°. We can create an equation and simplify:
15 + x = 90
x = 75

A watering can dispenses water at the rate of 0.3 gallon per minute. The original volume of water in the can was 7 gallons. Which set of ordered pairs shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after the can starts dispensing water? (1 point)
{(1, 6.7), (2, 6.4), (3, 6.1)}
{(1, 7.0), (2, 6.7), (3, 6.4)}
{(6.7, 1), (6.4, 2), (6.1, 3)}
{(7.0, 1), (6.7, 2), (6.4, 3)}
Answer:
The correct ordered pairs are:
{(1, 6.7), (2, 6.4), (3, 6.1)}
Option A is correct.
Step-by-step explanation:
A watering can dispenses water at the rate = 0.3 gallon per minute
The original volume of water in the can = 7 gallons.
Which set of ordered pairs shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after the can starts dispensing water?
First making the function:
The the volume of water in the can in gallons is represented by y and time in minutes is represented by x. Initially the volume is 7 gallons, after than water dispense at rate of 0.3 gallon per minute so, the function will be:
y=7-0.3(x)
Now, putting values to find ordered pairs
So, when time is 1 minute i.e x = 1
y=7-0.3(1)
y=7-0.3
y=6.7
So, when x=1, y=6.7 the ordered pair is: (1,6.7)
when time is 2 minutes i.e x = 2
y=7-0.3(2)
y=7-0.6
y=6.4
So, when x=2, y=6.4 the ordered pair is: (2,6.4)
when time is 3 minutes i.e x = 3
y=7-0.3(3)
y=7-0.9
y=6.1
So, when x=3, y=6.1 the ordered pair is: (3,6.1)
So, the correct ordered pairs are:
{(1, 6.7), (2, 6.4), (3, 6.1)}
Option A is correct.

While taking a ride in a hot-air-balloon in Napa Valley, Francisco wonders how high he is. To find
out, he chooses a landmark on the ground that is to the east of the balloon and measures the angle of
depression to be 54°. A few minutes later, after the balloon floats horizontally 100 feet east, closer to the
landmark, the angle of depression to the same landmark is determined to be 61°. Determine the height h
of the balloon. Round your answer to the nearest tenth.
a) Find the measures of ∠1, ∠2, ∠3 and ∠4:
∠1 = ________ ∠2 = ________
∠3 = ________ ∠4 = ________
b) Solve for the height of the balloon, h. You may use any
appropriate method but must show your work!

Question 5 of 17
Which steps show how to use the distributive property to evaluate9 - 67?
O A. 9(67) = 9(70 - 3) = 9 . 70 +9-3 = 630 + 27 = 657
O B. 9(67) = 9(70
OC. 9(67) = 9(70 – 3) =9 .70 – 3 = 630 - 3 = 627
OD. 9(67) = 9(70– 3) = 9.70- 70 3 = 630 - 210 = 420
3) =9.70 -93= 630 -27 = 603

Answer:
Step-by-step explanation:
circumference C=2*3.14*r
C=2*3.14*18m=113.04 m
Answer:
113.04 meters.
