Zane needs 20 yards of fencing to go around his rectangular yard. What are possible dimensions for Zane's yard? Select all that apply .
Answer:
1 yard by 9 yards
2 yards by 8 yards
3 yards by 7 yards
4 yards by 6 yards
Step-by-step explanation:
the perimeter of the rectangular yard needs to be 20 yards
Perimeter of a rectangle = 2 x ( length + width)
20 = 2 x ( length + width)
( length + width) = 20 /2
( length + width) = 10
The sum of the length and width should equal 10
Possible dimensions that would equal 10 are :
1 yard by 9 yards
2 yards by 8 yards
3 yards by 7 yards
4 yards by 6 yards

HELP ASAP
What is the value of x?
Answer:
47 degrees
Step-by-step explanation:
This is a parallel line, and this sort of angle is known as an alternate angle, which is a z shaped angle (can be a Z either way). Alternate angles are equal, therefore x=47 degrees too. Hope this helps :)
There are children in a play the ratio of 1;1 the ratio of girls who csan sing to girls who cant sing is 1;1 8 girls can sing
Answer:
8 girsl can sing
8 girls cannot sing
Total number of girls = 16
Step-by-step explanation:
The ratio of girls who csan sing to girls who cant sing is 1:1
Which means the number of girls who can sing and cannot sing are equal .
IF the number of girls who can sing is 8 then the number of girls who cant sing is also 8.
8:8
Dividing both sides by 8 gives
1:1
The total number of girls would be (8+8= )16.

Step-by-step explanation:
At a high school, the probability that a student is a senior is 0.20. The probability that a student plays a sport is 0.15. The probability that a student
IS a senior and plays a sport is 0.05.
What is the probability that a randomly selected student plays a sport, given
that the student is a senior?
A. 0.33
B. 0.05
C. 0.25
D. 0.15
Answer:
Choice C
Step-by-step explanation:
Conditional Probability formula
P(B | A) = [tex]\frac{P(A and B)}{P(A)}[/tex]
P(B | A) = Probability of event B, given probability of event A
P( A and B) = Probability of event A and event B = 0.05
P(A) = Probability of event A = 0.20
P(B | A) = [tex]\frac{0.05}{0.20}[/tex]
P(B | A) = [tex]\frac{1}{4}[/tex] = 0.25

6x+3x+1+4=09x+5=09x=-5x=-5/9Lamar has a list of 600 pages to read to finish his book for his upcoming book report. He sets a goal to read half of the pages left in his book each day.
Answer:
a.) Total pages Lamar have to read the first day to meet his goal = 300
Total pages left to read after 3 days = 75
b.) Total pages he need to read on day 8 = 4.6875
Step-by-step explanation:
The exact question is as follows :
Given - Lamar has a list of 600 pages to read to finish his book for his upcoming book report. He sets a goal to read half of the pages left in his book each day.
To find -
a) How many pages will Lamar have to read the first day to meet his goal?
How many will he have left to read after 3 days?
b) How many pages will he need to read on day 8?
Solution -
Given that,
Total number of pages = 600
Now,
In Day 1 ,
He will finish half of the pages
So, he finished pages = [tex]\frac{1}{2} (600)[/tex] = 300
i.e.
In Day 1 , he Finished 300 pages.
So,
At the end of Day 1, total pages left = 600 - 300 = 300
so,
Total pages Lamar have to read the first day to meet his goal = 300
Now,
For day 2 ,
Total pages = 300
He will finish half of the pages
So, he finished pages = [tex]\frac{1}{2} (300)[/tex] = 150
i.e.
In Day 2 , he Finished 150 pages.
So,
At the end of Day 2, total pages left = 300 - 150 = 150
Now,
For day 3 ,
Total pages = 150
He will finish half of the pages
So, he finished pages = [tex]\frac{1}{2} (150)[/tex] = 75
i.e.
In Day 3 , he Finished 75 pages.
So,
At the end of Day 3, total pages left = 150 - 75 = 75
So,
Total pages left to read after 3 days = 75
Now,
For day 4 ,
Total pages = 75
He will finish half of the pages
So, he finished pages = [tex]\frac{1}{2} (75)[/tex] = 37.5
i.e.
In Day 4 , he Finished 37.5 pages.
So,
At the end of Day 4, total pages left = 75 - 37.5 = 37.5
Now,
For day 5 ,
Total pages = 37.5
He will finish half of the pages
So, he finished pages = [tex]\frac{1}{2} (37.5)[/tex] = 18.75
i.e.
In Day 5 , he Finished 18.75 pages.
So,
At the end of Day 5, total pages left = 37.5 - 18.75 = 18.75
Now,
For day 6 ,
Total pages = 18.75
He will finish half of the pages
So, he finished pages = [tex]\frac{1}{2} (18.75)[/tex] = 9.375
i.e.
In Day 6 , he Finished 9.375 pages.
So,
At the end of Day 6, total pages left = 18.75 - 9.375 = 9.375
Now,
For day 7 ,
Total pages = 9.375
He will finish half of the pages
So, he finished pages = [tex]\frac{1}{2} (9.375)[/tex] = 4.6875
i.e.
In Day 7 , he Finished 4.6875 pages.
So,
At the end of Day 7, total pages left = 9.375 - 4.6875 = 4.6875
So,
At the starting of Day 8,
Total pages = 4.6875
So,
Total pages he need to read on day 8 = 4.6875

Create a histogram of this data.
To create a histogram, hover over each age range on the x-axis. Then click and drag up to plot the data.
Answer:
Step-by-step explanation:
When we are creating a histogram it's best to create a range for the different variables that are available.
So for the sake of covering all the possible ranges from 1 - 22, we should divide it into 5 categories.
0 - 5
6 - 10
11 - 15
16 - 20
21 - 25
Now that we have a set of ranges for the different variables, we can find the frequencies.
0 - 5 : 3
6 - 10 : 2
11 - 15 : 3
16 - 20 : 1
21 - 25 : 3
Since we have this we just add it to the histogram.
It should look like the image attachted below, I hope this helps :)

Step-by-step explanation:
Melinda takes out a loan to purchase a car. The balance on her loan after x months is represented by the equation y = 10,000 – 250x and the value of the car after x months is represented by y = 8,000 – 50x. Which statement describes when Melinda’s loan will be equal to the value of the car?
After 10 months, the loan and value of the car will both be equal to $7,500.
After 12 months, the loan and value of the car will both be equal to $7,000.
After 14 months, the loan and value of the car will both be equal to $6,500.
After 16 months, the loan and value of the car will both be equal to $6,000.

What is the area of this triangle?
h = 12 in.
b = 3 in.
Answer:
answer: 18
Step-by-step explanation:
Hello to find area in triangle you just have to do...
base × height ÷ 2 = area So our base is 3 and our height is 12 so 3 × 12 = 36 then 36 ÷ 2 = 18 Hope that helps!

The scale for the diagram of the doghouse is 1 in: 3 ft.
Find the length of the actual doghouse.
Answer:
2.25 feet
Step-by-step explanation:
Alright so the scale is 1:3
(1 represents the diagram and 3 represents the actual doghouse)
In the diagram the length is 0.75ft
We can use this Information to set up this equation:
[tex]\frac{1}{3}=\frac{0.75}{x}[/tex]
Simplify: (cross multiply, if confused scroll down, I explained)
x=3(0.75)
x=2.25
Length of actual house is 2.25 feet.Hope this helps
*************************
Cross multiplying:
It's simply this:
If [tex]\frac{a}{b}=\frac{x}{y}\\[/tex]
Then we can say
a(y)=b(x)

work out the coordinates of the points of intersection of the graphs
y= 4x^2+8x+3 and y=x+5
Answer (_____,_____) and (______,______)
Step-by-step explanation:
The point of intersection occurs when the two graphs have equal values of x and y at the same time. There is only one solution, because two straight lines can only intersect once.
[tex]y =4x^2 + 8x + 3 , y = x + 5\\\\4x^2 + 8x + 3 = x +5\\\\4x^2 + 8x + 3 -x -5 = 0\\\\4x^2 +7x -2 =0\\\\4x^2 + 8x -x - 2 = 0\\\\4x(x + 2) -1(x+2) = 0\\\\(4x - 1)(x+2) =0\\\\4x -1 = 0 , x+2 =0\\\\x = \frac{1}{4}, -2[/tex]
[tex]x_1 = \frac{1}{4}, x_2 =-2[/tex]
[tex]y_1 = 4x^2 + 8x + 3 \\\\x_1 = \frac{1}{4}\\\\y_1 = 4(\frac{1}{4})^2 + 8(\frac{1}{4}) + 3 = \frac{1}{4} + 2 + 3 = \frac{1}{4} +5 = \frac{21}{4}\\\\y_2 = x+ 5\\x_2 = -2\\y_2 = -2 + 5 =3[/tex]
Answer :
[tex](x_1, y_1) = (\frac{1}{4} , \frac{21}{4})\\\\(x_2,y_2) = (-2, 3)[/tex]
Answer:
(- 2, 3 ) and ([tex]\frac{1}{4}[/tex], [tex]\frac{21}{4}[/tex] )
Step-by-step explanation:
Given the 2 equations
y = 4x² + 8x + 3 → (1)
y = x + 5 → (2)
Substitute y = 4x² + 8x + 3 into (2)
4x² + 8x + 3 = x + 5 ( subtract x + 5 from both sides )
4x² + 7x - 2 = 0 ← in standard form
(x + 2)(4x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
4x - 1 = 0 ⇒ 4x = 1 ⇒ x = [tex]\frac{1}{4}[/tex]
Substitute these values into (2) for corresponding values of y
x = - 2 : y = - 2 + 5 = 3 ⇒ (- 2, 3 )
x = [tex]\frac{1}{4}[/tex] : y = [tex]\frac{1}{4}[/tex] + 5 = [tex]\frac{21}{4}[/tex] ⇒ ([tex]\frac{1}{4}[/tex], [tex]\frac{21}{4}[/tex] )

HELPP find the area of this shape / will mark brianliest
Answer:
222 cm
Step-by-step explanation:
To find the area of the square we multiply length and height.
15x12 = 180
For the triangular part of the trapezoid we multiply height by width and divide by 2.
12x7 = 84 / 2 = 42
Add the two sums and we get 222 cm.
180 + 42 = 222
