Ms. Reynold's sprinkler system has 5 stations that water all parts of her front and back lawn. Each station runs for an equal amount of time. If it takes 16 minutes for the first 2 stations to water, how long does it take to water all parts of her lawn?
Answer: 40 minutes
Step-by-step explanation:
It takes 16 minutes for the first 2 stations to water their sections which means that the time taken per station is:
= 16/2
= 8 minutes per station
Ms. Reynolds has 5 stations.
Total time taken will therefore be:
= 8 * 5
= 40 minutes

7.1 x 7.1 for the square = 50.41
7.1 divided by 2 = 3.55
3.55 x 4.75= 16.86
Normally here you would divide by 2, but you don’t need two because there is 2 triangles that are the same
Add the 50.41 and the 16.86 and you have your answer!

A robin can fly 10 miles per hour faster than a blue jay. It takes a robin 1 1/2 hours to fly 45 miles.
How many hours will it take a blue jay to fly that same distance?
Answer: [tex]2\dfrac14\text{ hours}[/tex]
Step-by-step explanation:
Given: It takes a robin [tex]1\dfrac12[/tex] hours to fly 45 miles.
[tex]1\dfrac12=\dfrac32[/tex]
Speed of robin= [tex]\dfrac{distance}{time}=\dfrac{45}{\dfrac32}[/tex]
[tex]\dfrac{45}{3}\times2= 15\times2= 30\text{ miles per hour}[/tex]
A robin can fly 10 miles per hour faster than a blue jay. It
Speed of Blue jay = Speed of robin - 10 miles per hour
= 30 miles per hour - 10 miles per hour
= 20 miles per hour
Time taken to cover 45 miles = [tex]\dfrac{45}{20}=\dfrac{9}{4}=2\dfrac14\text{ hours}[/tex]
Hence, it will take [tex]2\dfrac14\text{ hours}[/tex] by a blue jay to fly that same distance.

By taking 180° (The degree of a striaght line) and subract by the other angle (32°) you'll get the answer!!
the 4 angles of heptagon equal and each of other 3 is 20° greater the first 4.Find the angles
Answer:
interior angle of a heptagon = 900 degrees
900 = 4x + (3x + 60)
840 = 7x
840/7 = 120
X = 120
120 X 4 = 480
120 X 3 = 360
480 + 360 + 60 = 900
4 angles = 120 degrees each
3 angles = 140 degrees each
A jar contains 21 marbles: 8 white, 3 green, and 10 red. Write the described ratio in simplest form.
A. number of white marbles to number of green marbles.
Answer:
The question you posted was a bit confusing for me, but I'm assuming that you want the simplified ratio of the number of white marbles to the number of green marbles.
The answer would be 8:3.
Step-by-step explanation:
There are 8 white marbles and 3 green marbles, so you get 8:3. And since 8 and 3 are relatively prime, no simplifying is needed.
The answer is 8:3.

For the following right triangle, find the side length x.
Answer:
x = 17
Step-by-step explanation:
Since its a right triangle, you can use Pythagorean Theorem.
8² + 15² = x² (Given)
64 + 225 = x² (Simplify)
289 = x² (Add like terms)
17 = x (Square root both sides)
You are printing out information packets for your company. You will need a total of 6,400 pages to complete all of the packets. How many reams of 500 pages each will you need in order to print out all of these packets?
Answer:
13 reamsStep-by-step explanation
Given
Total number of pages to complete the packet = 6400 pages
If each ream contains 500pages, then:
Total number of reams needed = Total pages/number of pages per ream
Total number of reams needed = 6400/500
Total number of reams needed = 12.8
Hence you will need about 13 reams for all the packets

During their last game, the Miami Dolphins scored times for a total score of ͵Ͳ points. They scored points for each touchdown and ͵ points for each field goal. Write and solve the systems of equations to find the total touchdowns and field goals scored.
Answer:
The Miami Dolphins had 3 touchdowns and 3 field goals.
Step-by-step explanation:
It is given that During their last game, the Miami Dolphins scored 6 times, for a total score of 30 points. They scored 7 points for each touchdown and 3 points for each field goal.
We need to write and solve the system of equations to find the total touchdowns and field goals scored.
Let x represents the number of touchdowns.
Let y be the number of field goals.
It is given that the Miami Dolphins scored 6 times
[tex]x+y=6[/tex]
[tex]x=6-y[/tex]....(1)
They scored 7 points for each touchdown and 3 points for each field goal.
The total score is 30 points:
[tex]7x+3y=30[/tex] ...(2)
Put the value of x from equation (1) into equation (2).
[tex]7( 6-y)+3y=30[/tex]
[tex]42-7y+3y=30[/tex]
[tex]-4y=30-42[/tex]
[tex]-4y=-12[/tex]
[tex]y=3[/tex]
Put y = 3 in equation 1.
[tex]x=6-3[/tex]
[tex]x=3[/tex]
Hence, the Miami Dolphins had 3 touchdowns and 3 field goals.

Find two consecutive even integers such that the sum of the smaller and 3 times the larger is 330
I am so stuck please any one help
Answer:
The 2 numbers = 81 and 83
Step-by-step explanation:
As, one number = x
The other, because it's an even number and consecutive = x + 2
So the larger numbef here is x + 2
And they are saying 3 times x + 2 plus x = 330
So let's solve!
3 times x + 2 = 3(x+2) = 3x + 6
So we will add it to x = (3x + 6) +(x) = 4x + 6
So they are saying the sum of them will be 330
So, 4x + 6 = 330
4x = 330 - 6
4x = 324
x = 324/4
x = 81
So x is the first number = 81
And the second is x + 2 = 81 + 2 = 83
So the 2 numbers are 81, 83
Lets check!
3 times the bigger number = 83 x 3 = 249
We will add it to 81 and we will get 330
So, 249 + 81 = 330
So the answer is right

Which of these grids is shaded red and blue in the ratio 1:2?
The number of red cells are 4 and the number of blue cells are 8. Then the correct option is C.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
In the grids, there are 12 square box.
Let R be the red and B be the blue.
R + B = 12 ...1
R / B = 1/2 ...2
By solving equation 1 and 2, we have
R + 2R = 12
3R = 12
R = 4
Then
4 + B = 12
B = 8
Then the correct option is C.

Find the value of y....?
Answer:
B) 12
Step-by-step explanation:
(9y + 7)° + (7y - 19)° = 180° (interior angles in the same side of transversal)
(9y + 7 + 7y - 19)° = 180°
(16y - 12)° = 180°
16y - 12 = 180
16y = 180 + 12
16y = 192
y = 192/16
y = 12
Answer:
9y+7=7y-19
7+19=7y-9y
26=-2y
26/-2=-2y/-2
y=-13
