Erwin Elementary decided to plant a garden. They set up a rectangle that was
20.75 meters by 15.8 meters. What is the perimeter of the garden? *
Answer:
P = 73.1 m
Step-by-step explanation:
The length of a rectangle, l = 20.75 m
The width of a rectangle, b = 15.8 m
We need to find the perimeter of the garden. The formula for the perimeter of a rectangle is given by :
P = 2(l+b)
Substitue all the values,
P = 2(20.75+15.8)
P = 2(36.55)
P = 73.1 m
So, the perimeter of the garden is 73.1 m.

(9,1 ) is the solution of 64(x-8)²+ 12y² < 144 inequality.
What is solution for inequality?A solution for an inequality in x and y are numbers such that when we substitute that number for x and y we have a true statement.
We substitute x = 9 and y = 1 in each inequality. The inequality, for which the values satisfy, has (9, 1) as the solution.

A. y = -3x - 2
B. y = 1/3x - 2
C. y = 3x - 2
D. y = 3x - 2
Answer:
Your answer will be y=3x-2
Our form of slope is y=mx+b. B=y intercept...mx=slope y=will usually stay y. The y intercept is at -2 which where the line finally touches that y axis and is why u can see at the end of the equation it says -2. 3 is the slope in the middle because if you start from the y intercept, -2 and go up 3 times and over to the right once you will meet another point. This is called rise over run...the rise is 3 and the run is 1, now we put the rise over run as a fraction, 3/1 which equals 3. Therfore the slope is 3. And if we put those two numbers together you get y=3x-2

what is 75:___= 25:8
Answer:
24
Step-by-step explanation:
75/3 is equal to 25... So, in theory, if you multiply 8 by 3, you should get 24. To check that: 75/24 = 25/8
Answer:
24
Step-by-step explanation:
Considering that 25 can go into 75 by being multiplied by 3, you'd multiply 8 by 3 to get your answer.
Brianna's parents earned $43,329 for the year. During the year they paid $9,966 in taxes. At the end of the year when taxes are calculated, they calculate that they need to pay $11,660 in total taxes. How much more will they need to pay?
Answer:
1694
Step-by-step explanation:
The $43,329 in this question is just to trick you, so don't worry about this number.
We know her parents have already payed $9,966 for this years taxes.
But they need to pay a total of $11,660 for the year.
11,660 - 9966
=1694

At 2:00 P.M., a radio announcer reported that the temperature was 25°C. From 11:00 A.M. To 2:00 P.M. The temperature had risen 4°C. From 8:00 A.M. To 11:00 A.M. The temperature had risen 3°C. What was the temperature at 8:00 A.M.?
Answer:
The temperature at 8:00 A.M. was 18º C.
Step-by-step explanation:
Given that at 2:00 P.M., a radio announcer reported that the temperature was 25 ° C, and that from 11:00 A.M. to 2:00 P.M. the temperature had risen 4 ° C, while from 8:00 A.M. to 11:00 A.M. the temperature had risen 3 ° C, to determine what was the temperature at 8:00 A.M. the following calculation must be performed:
25 - 4 - 3 = X
21 - 3 = X
18 = X
Thus, the temperature at 8:00 A.M. was 18º C.

Find an equation in standard form for the hyperbola with vertices at (0, ±10) and asymptotes at
y = ± [tex]\frac{5}{6} x[/tex]
Answer:
[tex]\frac{y^2}{100} -\frac{x^2}{144} =1[/tex]
Step-by-step explanation:
By looking at the characteristics given, it can be determined that the equation will be vertical.
Being that the center is the midpoint of the vertices, the center is (0,0).
We have determined that the equation is vertical, so the equation used to find the asymptotes is [tex]y= k+\frac{a}{b} (x-h)\\ \\y=k-\frac{a}{b} (x-h)[/tex] . ± [tex]\frac{5}{6}[/tex] x is the asymptote.
We know that a is equal to 10 because of the vertices, so a squared is equal to 100.
[tex]\frac{a}{b} =\frac{5}{6}[/tex]
[tex]\frac{5}{6} =\frac{10}{b}[/tex]
When you cross multiply, and solve for b, you should get 12. Because b is 12, b squared is 144.
Now just fill the vertical transverse axis equation.
[tex]\frac{y^2}{100} -\frac{x^2}{144} =1[/tex]
