What is 20 percent of 70 plants

2 answers:

8 0

To find the percent of a number, multiply seventy by the decimal for of the percent.

Remember, 20% = .20

.2 • 70 = 14

ANSWER: 14 plants

BONUS: If you are given two numbers, say, "What percent of 70 is 14?"
Simply divide 14 by the original number, 70.
14/70 = .2 = 20%

This is also a good way to check your answers.

Hope this helps you! (:

Given the linear equation 3x + y = 5, find the slope of its graph

umka2103 [35]

Answer:

B) -3

Step-by-step explanation:

1. First you have to write the equation in slope intercept form. To do that, you must have y be alone on one side.

2. move the 3x to the right side with the 5 by subtracting 3x from both sides. Since 3x will cancel on the left, y will be left alone. $y=-3x+5$

3. Now that you're in slope intercept form, you can find the slope easily. The slope will always be the number in front of x. In this case, the number in front of x is -3. Therefore, -3 is your slope!

Find the derivative of f(x) = 2x^2 - 4x +3

ivolga24 [154]

Explanation

$2x^2-4x+3$

When taking derivatives of polynomials, we primarily make use of the power rule.

Power rule.

$\begin{gathered} f(x)=x^n \\ \text{then} \\ f^{\prime}(x)=nx^{n-1} \end{gathered}$

also, the derivate of a sum is the sum of the derivates

hence

$\begin{gathered} g(x)=f(x)+h(x)+\ldots z(x) \\ g^{\prime}(x)=f^{\prime}(x)+h^{\prime}(x)+\ldots.z^{\prime}(x) \end{gathered}$

Step 1

apply:

$\begin{gathered} f(x)=2x^2-4x+3 \\ f^{\prime}(x)=2\cdot2x^{2-1}-4(1)x^{1-1}+ \\ f^{\prime}(x)=4x^{}-4(1)x^0+3^0 \\ f^{\prime}(x)=4x^{}-4(1)(1) \\ f^{\prime}(x)=4z-4 \end{gathered}$

therefore, the answer is

classify the following triangle. check all that apply. A: Acute B: Right C: Obtuse D: Equilateral E: Scalene F: Isosceles

Maurinko [17]

Answer:

Step-by-step explanation:

Acute : An acute triangle is one in which all the angles less than 90 degree.

Right: Any triangle whose one angle measure is 90 degrees is called Right angled triangle.

Obtuse angle: Any triangle whose one angle measures more than 90 degrees is called Obtuse angled triangle.

Equilateral : Any triangle whose all the sides are equal are called equilateral triangle. They also have all the angle equal which measures 60 degrees.

Scalene triangle : The triangle whose length of all the sides are different from each other are called scalene triangle.

Isosceles : the triangle whose two sides length are equal are called Isosceles triangle.
