2x + 5y = 10
i need the slope and y-intercept
Answer:
Slope: [tex]-\frac{2}{5}[/tex]
Y-intercept: 2
Step-by-step explanation:
We have to isolate y;
2x + 5y = 10
5y = -2x + 10
y = [tex]\frac{-2x + 10}{5}[/tex]
y = [tex]-\frac{2}{5} x + 2[/tex]

The heights of the pine trees in a certain forest are normally distributed, with a mean of 86 feet and a standard deviation of 8 feet.
Approximately what percentage of the pine trees in this forest are taller than 100 feet?
Answer:
4%
Step-by-step explanation:
We solve this question using z score formula
z = (x-μ)/σ,
where
x is the raw score = 100 feet
μ is the population mean = 86 feet
σ is the population standard deviation = 8 feet
Hence,
x > 100 feet
z = (100 - 86)/8
z = 1.75
Probability value from Z-Table:
P(x<100) = 0.95994
P(x>100) = 1 - P(x<100) = 0.040059
Converting to Percentage
= 0.040059 × 100
= 4.0059%
Approximately = 4%
Therefore, the percentage of the pine trees in this forest are taller than 100 feet is 4%

question:
How many cubes with side lengths of \dfrac12 \text{ cm} 2 1 cmstart fraction, 1, divided by, 2, end fraction, start text, space, c, m, end text does it take to fill the prism?
Step-by-step explanation:
81 cubes are needed to fill the prism
Step-by-step explanation:
Volume of prism = 3 cubic units
Side lengths of cube = 1/3
Therefore the volume of the cube is,
V = a³ (a = side of the cube)
V = 1/3 × 1/3 × 1/3
= ( 1/3 )³
= 1/27 cubic units
To find the number of cubes needed to fill the prism, we need to divide the volume of cube by volume of the prism.
Number of cubes to fill the prism= Volume of prism / Volume of cube
= 3÷1/27
=3×27/1
= 81
Therefore, 81 cubes are needed to fill the prism

please help for all equations please. use the pythagorean theorem!!! i will give brainlyiest to the most helpful answer
Answer:
Do 15^2 +10^2=c^2 than put answer Into \sqrt()
Step-by-step explanation:
Step-by-step explanation:
Ok, so the pythagorean theorem is a^2 + b^2 = c^
where c is the hypotenuse and b and a are the the other 2 sides
9) 10^2 + b^2 = 15^2
100 + b = 225
-100 -100
b^2 = 125
sqrt of 125 = 5
b = 5
10) 2^2 + 5^2 = C^2
4 + 25 = c^2
sqrt of 29 = c
c = [tex]\sqrt{29\\}[/tex]
11) 42^2 + a^2 = 48^2
1764 + a^2 =2304
-1764 -1764
a^2 = 540
a = [tex]6\sqrt{15}[/tex]

211
22
266
Which equation best describes the relationship between the total cost, c(t), and the number of T-shirts, t?
ok
Answer:
12
Step-by-step explanation:
hi
Equation which describe relationship between total cost and number of t-shirt is [tex]c(t)=75.93e^{0.06t}[/tex].
Data given are ,
Number of t-shirt (t) total cost c(t)
12 156
17 211
22 266
According to above table, exponential function best describes the relationship between the total cost, c(t), and the number of T-shirts, t.
Let, [tex]c(t)=Ae^{kt}[/tex]
Substitute , t=12 and c(t) = 156
We get, [tex]156=Ae^{12k}.......(1)[/tex]
Substitute , t=17 and c(t) = 211
We get, [tex]211=Ae^{17k} ........(2)[/tex]
After solving above equations.
We get, A = 75.93 and k = 0.06
Thus, [tex]c(t)=75.93e^{0.06t}[/tex]

A map of a highway has a scale of 2 inches equals 33 miles. The length of the highway on the map is 6 inches. There are 11 rest stops equally spaced on the highway, including one at each end. You are making a new map with a scale of 1 inch equals 30 miles. How far apart are the rest stops on the new map?
(nvm)

Which value of x is the solution to the equation 4(-3x+8)= -16?
answer choices:
1. -4
2. -2
3. 2
4. 4
explain
Answer:
x = 4
Step-by-step explanation:
4(-3x + 8) = -16
Divide both sides by 4
-3x + 8 = -4
Subtract 8 from both sides
-3x = -12
Divide both sides by -3
x = 4

Will give brainliest if correct! Which of the following is not a solution to the inequality 3−(7−2x)>−8?
A) -3
B) -1
C) 0
D) 1
Answer:
-3
Step-by-step explanation:
3-(7-2x) > -8
get rid of the parentheses because there is a minus sign before them
3-7+2x > -8
replace x with all the numbers (one by one not all at once) and see if the equation is correct until you find the number that makes it incorrect.
EXAMPLE:
3-7+2(1) > -8 parentheses next to a number means multiply
3-7+2 > -8
3-7 = -4
-4 + 2 = -2
-2 is greater than -8

50
Step-by-step explanation:
Alright, so two of the points are: (0,25) (1,75)
Now we line them up:
(0,25)
(1, 75)
And, 0 to 1 has "1" as a difference.
That'll go on the bottom.
25 to 75 has a "50" difference.
That goes on top.
And then we get the slope of 50.

Answer: 1306.5 m^3
Step-by-step explanation:
1. The formula for the volume of a cylinder is: V=[tex]\pi[/tex]r^2h
2. If you substitute the values into the equation, you get
V = pi * 5.7^2 * 12.8 = 1306.5
3. 1306.5 is already to the nearest tenth, so that is the answer.
