Answer:
(-4, 1)
Step-by-step explanation:
Solve it as a system of equations:
[tex]3x-2y=-14\\3x+y=-11[/tex]
subtract the two equations
[tex]-3y = -3[/tex]
divide both sides by -3
[tex]y=1[/tex]
Plug this into the equation 3x + y = -11 to solve for x
[tex]3x + 1 = -11\\[/tex]
subtract 1 from both sides
[tex]3x = -12[/tex]
divide both sides by 3
[tex]x = -4[/tex]
So the answer is (-4, 1)

Answer:
9/16
Step-by-step explanation:
First, note that 10000 multiplied by .5625 will get rid of the decimal point. Therefore, make a fraction where the numerator is .5625 times 10000 and denominator is 10000 like this:
.5625 x 10000
10000
Next, multiply the numbers in the numerator together and keep the denominator as is. Now our fraction looks like this:
5625 /10000
The greatest common factor of 5625 and 10000 is 625, which means you can divide the numerator and denominator by 625 and keep the same value:
5625 ÷ 625 /10000 ÷ 625
And when calculating the numerator and denominator in our fraction above, we get .5625 as a fraction in the simplest form possible:
.5625 =
9 /16

A circular pen has circumference of 77.5 feet. Approximate π to 3.14 and estimate how many sheep could be safely kept in the pen if each sheep needs at least 45 square feet.
Answer:
10 sheep
Step-by-step explanation:
First, we have to determine the area of the circular pen.
Area of a circle = [tex]\pi[/tex][tex]r^{2}[/tex]
But,
Circumference of a circle = 2[tex]\pi[/tex]r
So that,
77.5 = 2 x 3.14 x r
77.5 = 6.28r
r = 12.34
Radius of the pen is 12.34 feet.
Thus,
Area of the pen = [tex]\pi[/tex][tex]r^{2}[/tex]
= 3.14 x [tex](12.34)^{2}[/tex]
= 478.15
Area of the pen = 478.15 square feet
Number of sheep that can be safely kept in the pen = [tex]\frac{478.15}{45}[/tex]
= 10.63
The number of sheep that can be safely kept in the pen is 10.
What is the area of the triangle?
10 cm
10 cm
8 cm
12 cm
32 square centimeters
48 square centimeters
96 square centimeters
60 square centimeters
Answer: 48 cm.
Step-by-step explanation: Area of a triangle is equal to (base * height) / 2. (12 * 8) / 2 = 48
The heights, in feet, of the trees for sale at two nurseries are shown below.

which statement are true regarding the measurements of center in variability of these data sets/3 choices
Answer:
The mean of tree heights at Yard Works is 8 feet. The mean of tree heights at The Grow Station is 9 feet. The mean absolute deviations of the tree heights at both yards is 2.
Answer:
The heights, in feet, of the trees for sale at two nurseries are shown below.
Yard Works: 7, 9, 7, 12, 5
The Grow Station: 9, 11, 6, 12, 7
Which statements are true regarding the measures of center and variability of these data sets? Select three choices.
________________________________________________________
1 The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
2 The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.
3 The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
4 The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.
5 The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.
Step-by-step explanation:
Yard works has...
mean=8
median=7
mode=7
range=11
because in order it is 5 7 7 9 12
(5+7+7+9+12)/5=8
5 7( 7 )9 12 is the median
and seven occurs the most
and with this logic...
THE GROWSTATION has a
mean=9
median=9
mode=n/a
range=6
_______________________________________
YEA) The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
YEA) The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.
YEA) The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.
The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.

There are 10 students in a class:7 boys and 3 girls. If the teacher picks a group of 4 at random what is the probability that everyone in the group is a boy
Answer:
Step-by-step explanation:
Probability the first pick is a girl: 7/10
Probability the second pick is a girl: 6/9
Probability the third pick is a girl: 5/8
Probability of picking 3 girls:
7/10 * 6/9 * 5/8 =
= (7 * 6 * 5)/(10 * 9 * 8)
= (7 * 1 * 1)/(2 * 3 * 4)
=7/24

What are the ratios for SIN A and COS A
Answer:
A
Step-by-step explanation:
A good trick for trigonometric functions is to remember SOHCAHTOA:
Sin=Opposite over Hypotenuse
Cos=Adjacent over Hypotenuse
Tan=Opposite over Adjacent
The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.
So in this case, the sin of angle A (opposite over hypotenuse) would be [tex]\frac{24}{26}[/tex] and cos A (adjacent over hypotenuse) would be [tex]\frac{10}{26}[/tex].
I hope this helps!

At an amusement park, 40 percent of the tickets were sold in the first hour. If 800 tickets were sold in the first hour, which equation can be used to find the total number of tickets sold for the entire day?
StartFraction 800 divided by 40 Over 40 divided by 40 EndFraction = StartFraction 20 Over 1 EndFraction
StartFraction 100 divided by 4 Over 800 divided by 4 EndFraction = StartFraction 25 Over 200 EndFraction
StartFraction 40 times 20 Over 800 times 20 EndFraction = StartFraction 800 divided by 16,000 EndFraction
StartFraction 40 times 20 Over 100 times 20 EndFraction = StartFraction 800 Over 2000 EndFraction
Answer: 2000 tickets were sold
Step-by-step explanation:
8000 divided by 40 percent is 200
If 800 tickets were sold in the first hour, the equation representing the given condition is [tex]\frac{40 \times 20}{10 \times 200}= \frac {800}{2000}[/tex]. Option D is correct.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
If 800 tickets were sold in the first hour, the equation representing the given condition is [tex]\frac{40 \times 20}{10 \times 200}= \frac {800}{2000}[/tex]. Option D s correct.
It is given that 40 percent of the tickets were sold in the first hour and 800 tickets were sold in the first hour,
Let the total ticket be x
40% of x =800 tickets
x = 800/40%
x=800×100/40
x=20×100
x=2000
As a result
40% of 2000 =800 tickets
(40/100)×2000 = 800
Rearrange the equations we get,
800/2000=(40×20)/(100×20),
Hence, if 800 tickets were sold in the first hour, the equation representing the given condition is [tex]\frac{40 \times 20}{10 \times 200}= \frac {800}{2000}[/tex]. Option D is correct.

Answer:
We have been given that a car can travel 476 miles on 14 gallons of gas and we are asked to write an equation relating the distance d to the number of gallons g.
We can set an equation as distance traveled is directly proportional to number of gallons used in travelling that distance.
Now we will find out K(number of miles traveled in one gallon of gas) by substituting our given values in this equation.
Therefore, we can see that car travels 34 miles in one gallon of gas.
Now we can use this information to find out how many gallons of gas does this car need to travel 578 miles.
Let us divide number of miles to be traveled by number of miles traveled in one gallon of gas to find out number of gallons of gas needed.
Therefore, car need 17 gallons of gas to travel 578 miles.
Step-by-step explanation:
Step-by-step explanation:
476=14
578=X
578*14/476
8092/476=17
So the answer is 17 gallons
