Answer:

False for the first one

true for the second

true for the last

Step-by-step explanation:

The triangle with 2 angles as 90° is not possible and the statement is false

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ∠ABC

Now , the measures of the angles of the triangle are

A triangle has two 90° angles and a side 12 centimeters in length

So , ∠ABC = ∠BAC = 90°

And , For a Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

Therefore , a triangle cannot be formed with 2 angles as 90°

Hence , the statement is False

Answer:

  about 2.1

Step-by-step explanation:

The slope of the secant line is given by the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (121/100 -1)/(11/10 -1) = (21/100)/(1/10) = 2.1

The slope of the tangent is about 2.1.

_____

Additional comment

We can refine our estimate by choosing a secant line between the points (9/10, 81/100) and (11/10, 121/100). That is, points either side of x=1.

That slope is ...

  (121/100 -81/100)/(11/10 -9/10) = (40/100)/(2/10) = 2.0

We expect the slope of the tangent at x=1 to be exactly 2.0.

Answer:

5/16 Got a C

Step-by-step explanation:

A = 1/4 x 32

B = (32 - A)/2

D = 2

A = 8

B = (32 - 8)/2

B = 24/2

B = 12

D = 2

8 + 12 + 2 = 22

22/32 did not get a C

32/32 - 22/32 = 10/32

10/32 - > 5/16

Step-by-step explanation:

Problem 13)

Cancel  out in PAIRS the common factors in numerator and denominator

[tex]\frac{3m^4n^2}{2m^3n^4} =\frac{3m}{2n^2}[/tex]

which agrees with answer C

Answer:

y = 1.2x + 1.5

Step-by-step explanation:

Formula: y = mx + b

m = slope

b = y-intercept

The y-intercept is at "1.5"

slope = y/x or rise over run

r/r = 6/5 = 1.2

Slope is 1.2

Equation form....

y = 1.2x + 1.5

And the slope is positive since the line is increasing

Answer:

21.67

Step-by-step explanation:

look at the number next to 7 to determine how it will change.

The number is 3 which is under 5 so the 7 stays the same while 3 is gotten rid of

The solution is, The value of x is 8. so, the correct answer is option C.) 8.

Here, we have,

from the given diagram, we get,

In the diagram, LW is parallel to ST.

RL = 6 centimeters, LS = 3 centimeters, and WT = 4 centimeters.

as, we know that,

if, LW is parallel to ST , by property of triangle,

we get,

LW divides RT & RS proportionally.

i.e. RW: WT = RL : LS

now, here, RW = x

so, we have,

x: 4 = 6 : 3

or, x = 6 *4 / 3

or, x = 8

Hence, The value of x is 8.

Answer:

7p+7q+63

Step-by-step explanation:

Distributive property is basically just multiplying the outside number with the things that are in the parentheses. so 7*p is 7p, 7*q is 7q, and 7*9 is 63, so that makes your answer 7p+7q+63
