Answer:

D

Step-by-step explanation:

Numbers that cannot be expressed as fractions are considered irrational numbers

π cannot be expressed as fraction therefore it is an irrational number

√64 = 8 which can be expressed as a fraction therefore √64 is not an irrational number

-\frac{7}{8} is already expressed as a fraction therefore B is not the answer

.6 can be expressed is 6/10 therefore C is not the answer

Answer:

a) P = 6x + 13//

b) i) x = 5//

ii) 9//

Step-by-step explanation:

a) P = 2(x+2) + 2(2x-1) + 3 + 8 m

= 2x+4 + 4x-2 + 3 + 8

= 6x + 13//

b) i) P = 43 m

43 = 6x + 13

43-13 = 6x

<u>3</u><u>0</u> = <u>6</u><u>x</u><u> </u>

6 6

x = 5//

ii) longest side = (2x-1) m

2 × 5 - 1

10-1 = 9//

what is the quotient (65y3 15y2 − 25y) ÷ 5y? a. 13y2 3y − 5 b. 13y3 3y2 − 5y c. 13y2 − 3y 5 d.13y2 − 3y − 5
Aneli [31]

Keywords:

<em>Division, quotient, polynomial, monomial </em>

For this case we must solve a division between a polynomial and a monomial and indicate which is the quotient.

By definition, if we have a division of the form: \frac {a} {b} = c, the quotient is given by "c".

We have the following polynomial:

65y ^ 3 + 15y ^ 2 - 25y that must be divided between monomy5y, then:

C (y) represents the quotient of the division:

C (y) = \frac {65y ^ 3 + 15y ^ 2 - 25y} {5y}

C (y) = \frac {65y ^ 3} {5y} + \frac {15y ^ 2} {5y} - \frac {25y} {5y}

C (y) = 13y ^ 2 + 3y-5

Thus, the quotient of the division between the polynomial and the monomial is given by:

C (y) = 13y ^ 2 + 3y-5

Answer:

The quotient is: C (y) = 13y ^ 2 + 3y-5

Option: A

Jaquez bought a new tablet that retails for $199. If the store is currently
natta225 [31]

Answer:

$ 158.95

Step-by-step explanation:

Reduction = 25% of 199

                = 0.25 * 199

                = $ 49.75

Price of the tablet after reduction = 199 - 49.75 = $ 149.25

Sales tax = 6.5% of 149.25

              = 0.065 * 149.25

              = $ 9.70

Total price that he need to pay = 149.25 + 9.70

                                                      = $ 158.95

What are the rounded answers to each question?
matrenka [14]

For the given triangle, m∠G° = 51°, HI = 23.3 units, and GH = 18.9 units.

Step-by-step explanation:

Step 1:

In the triangle, the given angle is 39°, the hypotenuse side's length is 30 units. Assume the opposite side's length is x units.

To determine the opposite side's length, we determine the sin of the angle. To calculate the sin of an angle, we divide the opposite side's length by the hypotenuse's length.

sin\theta= \frac{oppositeside}{hypotenuse}, sin39=\frac{x}{30}.

0.6293 = \frac{x}{30} , x = 18.879.

GH measures 18.879 units. Rounding this off, we get 18.9 units.

Step 2:

Assume the side HI measures y units. According to Pythagoras' theorem,

30^{2}= 18.879^{2} +y^{2} , y^{2}=30^{2}-18.879^{2}.

y^{2} = 543.5834, y = 23.314.

So HI measures 23.314 units. Rounding this off, we get 23.3 units.

Step 3:

GHI is a triangle and all triangles have a total angle of 180°.

\begin{aligned}&\angle G^{\circ}+\angle H^{\circ}+\angle I^{\circ}=180^{\circ},\\&\angle G^{\circ}+90^{\circ}+39^{\circ}=180^{\circ},\\&\angle G^{\circ}=180^{\circ}-129^{\circ}=51^{\circ}.\end{aligned}

So ∠G° measures 51°.
