Mike:251×90=22,590 15% of 22,590 is 2,259

Answer:

D) 13

Step-by-step explanation:

a² + b² = c²

5² + 12² = c²

25 + 144 = c²

169 = c²

[tex]\sqrt{c^2} =\sqrt{169}[/tex]

c = 13

Answer:

Step-by-step explanation:

QA = QC = 5.9    ⇒    PA = 27.4 - 5.9 = 21.5

PB = PA = 21.5

CR = BR = 12.2

So, the perimeter:

P = 27.4 + 5.9 + 2×12.2 + 21.5 = 79.2

The perimeter of the triangle PQR is 79.2 units.

Perimeter of a straight sided figures or objects is the total length of it's boundary.

Given a triangle PQR.

An incircle is drawn inside the triangle.

We know that the length of the tangents which are drawn from an exterior point to the circle are equal.

Using this property and the given lengths,

PQ = 27.4

PR = (27.4 - 5.9) + 12.2 = 33.7

QR = 5.9 + 12.2 = 18.1

Perimeter of the triangle = 27.4 + 33.7 + 18.1 = 79.2 units

Hence the perimeter is 79.2 units.

Answer:

x = -4 + 3√2 and x = -4 - 3√2

Step-by-step explanation:

Complete the square of x^2+8x-2=0:

Between 8x and -2, write in 4^2 - 4^2, so that we now have:

x^2 + 8x + 16 - 16 - 2 = 0, or by writing x^2 + 8x + 16 as the square of a binomial, (x + 4)^2 = 18

Taking the square root of both sides, we get:

x + 4 = √18 = ±√9√2, or ±3√2

Then x = -4 + 3√2 and x = -4 - 3√2

Answer:

$92.25

Step-by-step explanation:

If Diego spent $20.50 and Sandy spent 4.5x as much as Diego, that means that Sandy spent 20.5x4.5, which equals 92.25. Sandy spent $92.25

Answer:

B (39)

Step-by-step explanation:

Using the Pythagorean theorem (a^2+b^2=c^2) and X=BC length

15^2+36^2=x

225+1296=x

√1521=x

x=39

Answer:

B.

Step-by-step explanation:

The Pythagorean Theorem

a^2+b^2=c^2

In this case it's c^2=a^2+b^2

c^2=15^2+36^2

c^2=225+1296

c^2=1521

c= the square root of 1521

c=39

So...

the length of line segment BC is 39

Q. 3

[tex]V_{cone} =565.2\: cm^3 [/tex]

Q. 4

[tex] V_{cone} =3,014.4\: cm^3 [/tex]

Step-by-step explanation:

Q. 3

Radius of the cone (r) = 6 cm

Height of the cone (h) = 15 cm

[tex]\because V_{cone} =\frac{1}{3} \pi r^2 h[/tex]

[tex]\therefore V_{cone} =\frac{1}{3}\times 3.14 (6)^2 (15)[/tex]

[tex]\therefore V_{cone} =\frac{1}{3}\times 3.14 (36) (15)[/tex]

[tex]\therefore V_{cone} =565.2\: cm^3 [/tex]

Q. 4

Radius of the cone (r) = 12 cm

Height of the cone (h) = 20 cm

[tex]\because V_{cone} =\frac{1}{3}\pi r^2 h[/tex]

[tex]\therefore V_{cone} =\frac{1}{3}\times 3.14 (12)^2 (20)[/tex]

[tex]\therefore V_{cone} =\frac{1}{3}\times 3.14 (144) (20)[/tex]

Answer:

our inputs are 3 & 1/2

Step-by-step explanation:

the ? is the slope and the slope is equal to 1/2 so

?=1/2

the point slope formula is

(y-y1)=m(x-x1)  (x1,y1)--> a point on the line  m--> slope

so we chose (x1,y1) as (3,0)

when we plug that in we get

y-0=1/2(x-3)

so our inputs are 3 & 1/2
