Can you find the base and height measurements for s triangle if you know that the area is 22 square units explain why or why not

1 answer:

8 0

Well,
area=1/2 times base times height
area=22
22=1/2 times base times height
mutily both isdes by 2/1 to clear ffraction
44=base times height

all we know that base times height =44
base could equal 1 and height culd equal 44
base could equal 11 and height equal 4

we cannot know exactly what the base and height are from the given data

Consider the equation

muminat

Answer:

A. $a=10\\ \\b\neq -8$

B. $a=10\\ \\b= -8$

Step-by-step explanation:

Consider the equation

$2(5x-4) = ax + b$

A. This equation has no solutions when the coefficients at x are the same and the free coefficients are not the same.

First, use distributive property:

$2(5x-4)=2\cdot 5x-2\cdot 4=10x-8$

So, the equation is

$10x-8=ax+b$

This equation has no solutions when

$a=10\\ \\b\neq -8$

B. The equation has infinitely many solutions when the coefficients at x are the same and the free coefficients are the same too.

So, the equation

$10x-8=ax+b$

has infinitely many solutions when

$a=10\\ \\b= -8$

In other cases, the equation has a unique solution

Will mark brainliest if correct’

mixer [17]

Answer:

-1280

Step-by-step explanation:

Given a₁ = -10, n = 8, r =2

Required to find nᵗʰ term.

From the general formula: aₙ= a₁ (r)ⁿ⁻¹

Therefore nᵗʰ = -10(2)⁸⁻¹

= -10(2)⁷

= - 10(128)

= - 1280

The means and mean absolute deviations of sidney’s and phil’s grades are shown in the table below. means and mean absolute devia

DochEvi [55]

The expression that represents the ratio of the difference of the two means to Sidney’s mean absolute deviation is given by: Option B: 4/3.28

<h3>What is mean absolute deviation?</h3>

Mean absolute deviation is the average of the absolute deviation of each observation from their mean, for a considered set of observations.

For this case, the table of mean and mean absolute deviation is given as:

$\begin{array}{ccc}&Mean&M.A.D.\\\text{Sidney}&82&3.28\\\text{Phill}&78&3.96\end{array}$

(M.A.D refers to Mean Absolute Deviation).

So, difference in their mean is 82 - 78 = 4

Absolute deviation for Sidney is 3.28

Thier ratio is: 4/3.28

Thus, the expression that represents the ratio of the difference of the two means to Sidney’s mean absolute deviation is given by: Option B: 4/3.28
