Area of a triangle:

A = 1/2bh

Given:

b = 20

h = 14

Work:

A = 1/2bh

A = 1/2(20)(14)

A = 10(14)

A = 140

Which answer is an equation in point-slope form for the given point and slope?

Naddika [18.5K]

Answer:

B $(y-9)=5(x-1)$

Step-by-step explanation:

Formula of straight line in Point slope form

$(y-y_1)=m(x-x_1)$

Here

$m=5 \ and \ (x_1, y_1)=(1, 9)$

therefore equation of line having slope 5 and passing through point )1, 9) is given as

$(y-9)=5(x-1)$

A Bill in the U.S House of Representatives passed because at least 2/3 of the members present voted in favor of it. If the bill

otez555 [7]

Answer:

Members of the House of Representatives present for the vote were atleast 426 .

Step-by-step explanation:

As given

A Bill in the U.S House of Representatives passed because at least $\frac{2}{3}$ of the members present voted in favor of it.

If the bill received 284 votes .

Let us assume that the total members of the House of Representatives were present for the vote be x .

Than the equations becomes

$\frac{2}{3}\times Total\ number\ of\ Representatives\ present\ for\ vote \geq 284$

$\frac{2}{3}\times x \geq 284$

$2x \geq 284\times 3$

$2x \geq 852$

$x\geq \frac{852}{2}$

$x\geq 426$

Therefore members of the House of Representatives present for the vote were atleast 426 .

A circle with radius of 2cm sits inside a circle with radius of 4cm What is the area of the shaded region

Klio2033 [76]

ANSWER

$12\pi \: {cm}^{2}$

EXPLANATION

We want to find the area of the shaded region.

We find the area of the smaller circle and subtract from the area of the larger circle.

Area of smaller circle is

$a = \pi \: \times 2^{2} = 4\pi$

Area of larger circle is

$A = \pi \: \times {4}^{2} = 16\pi$

The area of the shaded region is:

$16\pi - 4\pi = 12\pi$

Can someone help answer at least one? :) ty

Vika [28.1K]

Answer:

Step-by-step explanation:

a). Ratio of OP and RT = $\frac{OP}{RT}$

= $\frac{12}{3.6}$

= $\frac{10}{3}$

b). Since ΔOPQ ~ ΔRTS, their corresponding sides will be proportional.

$\frac{OQ}{RS}=\frac{OP}{RT}$

$\frac{OQ}{4.5}=\frac{10}{3}$

OQ = $\frac{10\times 4.5}{3}$

OQ = 15 cm

c). m∠P = m∠T = 60°

d). m∠Q = m∠S

By applying angle sum theorem in ΔRST,

m∠R + m∠S + m∠T = 180°

26° + m∠S + 60° = 180°

m∠S = 180° - 86°

= 94°

Therefore, m∠Q = m∠S = 94°
