Step-by-step explanation:

by subtraction of these 2 equation,

2p = 2

p = 1

Answer:

P - Q = - 11b² + 8b - 4

Step-by-step explanation:

P - Q

= - 4b² + 6b - 9 - (7b² - 2b - 5) ← distribute parenthesis by - 1

= - 4b² + 6b - 9 - 7b² + 2b + 5 ← collect like terms

= - 11b² + 8b - 4

Answer:

second option

Step-by-step explanation:

find angle c

angle a + angle c = 110 degree (sum of two interior opposite angle is equal to the exterior angle formed )

70 + angle c = 110

angle c = 110 - 70

angle c = 40 degree

find angle b

angle a + angle b + angle c = 180 degree (sum of interior angle of a triangle)

70 + angle b + 40 = 180

angle b + 110 = 180

angle b = 180 - 110

angle b = 70 degree

when two sides are equal the triangle can be named as isosceles triangle.

Answer:

option B

Step-by-step explanation:

∠ABD + ∠ABC = 180°            [ straight line angle ]

110° + ∠ABC = 180°

∠ABC = 180 - 110 = 70°

option A : False

Option B : True,

      Since two angles are same, the given triangle is isosceles.

option C : False

        Nothing mentioned about the sides in the figure. Though it is isosceles

      it does not mention anything about sides.

            If two angles of a triangle are congruent,

          then the sides opposite those angles are congruent.

          That is , AC = BC

Option D : False, Because only B satisfies.

The increasing order of maximum number of extrema they could have is;

The extrema of a polynomial is otherwise termed it's "turning point(s)". It follows that a polynomial with a degree n would have (n-1) number of turning points. It therefore follows on this basis that the arrangement of the polynomial equations in increasing order of possible extrema they could have is;

y = 3x² + 5

y = x³ + 21x + 2

y = x⁴ − 17x² + 72

y = x5 + 4x³ − 5x

y = x6 − 6x3 + 5x

If h > 42 and h < 60, where h is in inches, then we can say 42 < h < 60.

This translates to "the person's height must be between 42 inches and 60 inches, excluding both endpoints".

So for example, if someone is h = 50 inches, then they can go on the ride. This is because 42 < 50 < 60 is true. I've simply replaced h with 50.

On the other hand, something like 42 < 70 < 60 is false, meaning that h = 70 isn't allowed as they are too tall.

The person cannot have a height of h = 42, and they can't have a height of h = 60 either since we're leaving the endpoints out.

As a final example, if the person is h = 40 inches, then they can't ride either because 42 < 40 < 60 is false. They are too short in this case.

Answer:

12 3/5 pi

Step-by-step explanation:

First find the area of the circle

A = pi r^2

A = pi ^^2

A = 36 pi

Then find the fraction of the circle that is shaded

A circle is 360 degrees

126/360 =7/20

Multiply the area by the fraction

7/20 * 36 pi

63/5 pi

12 3/5 pi

Answer:

the area of sector is

[tex] \frac{126}{360} \times \pi \times 6 {}^{2} = \frac{63}{5} \pi[/tex]

Answer:

6.5cm)

Step-by-step explanation:

13.1 cm x 13.1 cm = 171.61

11.4 cm 11.4 cm = 129.96

171.61 - 129.96 = 41.65

Find the square root of 41.65.

41.65 = 6.4536811201050 x 6.4536811201050

Round 6.4536811201050.

Step-by-step explanation:

volume of a cylinder = 4/ 3 π r² h

=> 4817 = 4/ 3 × 22/ 7 × 4² × h

=> h = (4817 × 3 × 7)/ (4 × 22 × 4²)

=> h = 71.8

Answer:

Step-by-step explanation:

I would have thought the answer would be whole numbers...

using top line....

5x-5y + 7x-15 = 180 (that is a line)

12x - 5y = 195

using bottom line

4x+ 4y +2x+ y = 180

6x + 5y =180

~~~~~~~~~~~~~~~~~~

12x - 5y = 195

6x + 5y =180

(fives cancel)

18x = 375

x = 20.83

y= 11

Answer:

x=125/6

y=11

Step-by-step explanation:

Same side interior angles have a sum of 180 if the transversal passes through a pair of parallel lines.

So we have the following two equations:

7x-15+5x-5y=180

4x+4y+2x+y=180

Let's simply(combine like terms):

12x-5y-15=180

6x+5y=180

Add 15 on both sides for first equation:

12x-5y=195

6x+5y=180

Equations are set up so we can use linear combination or elimination (adding equations together to eliminate y):

18x=375

Divide both sides by 18:

x=375/18

Simplify (reduce fraction):

x=375/18 ÷3/3=125/6

Now let's go back and find y using either equation:

6x+5y=180 with x=125/6

6(125/6)+5y=180

125+5y=180

5y=180-125

5y=55

y=11

x=125/6 and y=11

Answer: 0.43ft²

Step-by-step explanation:

You didn't really specify part A but In assuming that the question you posted is part A. Anyways in this case, area will be calculated by multiplying the length by the width.

Since the piece of wood has a length that is 2.45 feet and width that is 2.097 inches, then the area will be:

= 2.45 × 0.17475

= 0.4281375 ft²

= 0.43ft² to nearest hundredths

Note 1 foot = 12 inches

Therefore, 2.097 inches = 2.097/12 = 0.17475 feet

Answer:

✔️2 sets of corresponding angles

<D and <S

<R and <L

✔️2 sets of corresponding sides

DR and SL

RM and LT

Step-by-step explanation:

When two polygons are congruent, it implies that they have the same shape and size. Therefore, their corresponding angles and sides are congruent to each other.

When naming congruent polygons, the arrangement of the vertices are kept in a definite order of arrangement.

Therefore, Given that polygon DRMF is congruent to SLTO, the following angles and sides correspond to each other:

<D corresponds to <S

<R corresponds to <L

<M corresponds to <T

<F corresponds to <O

For the sides, we have:

DR corresponds to SL

RM corresponds to LT

MF corresponds to TO

FD corresponds to OS.

We can select any two out of these sets of corresponding angles and sides as our answer. Thus:

✔️2 sets of corresponding angles

<D and <S

<R and <L

✔️2 sets of corresponding sides

DR and SL

RM and LT
