Answer:
Option 3 : ∠BAC = 60°
Step-by-step explanation:
Exterior angle = sum of interior opposite angles.
That is ,
2x + 3x = 150°
5x = 150°
x = 30
∠BAC = 2x = 2 × 30 = 60°
Answer:
The measure of <BAC is 60
Peter gets 1 star for every 3 correct answers he gets on khan academy. What is the minimum number of correct answers Peter must enter if he wants to get 12 stars?
For full points you need to write an equation that uses a variable and division, show what work you did to solve it, and then give me a final answer.
Answer:
Peter needs to get 36 problems correct to get 12 stars
Step-by-step explanation:
for every 3 correct answers, Peter gets 1 star
1/3
if he wants 12 stars he will have to get 'x' amount of questions correctly
considering this is constant, 1/3 will have to equal 12/x
[tex]\frac{1}{3} = \frac{12}{x} \\\\1x = 36\\[/tex]
1x = x, so you don't need to do anything to 36
therefore the answer is that you need to get 36 problems correct to get 12 stars
What is the measure of KPN?
Answer:
angle KPN=95 degree
Step-by-step explanation:
angle KPN = angle JPO (because they are vertically opposite angles)
Now,
angle JPO+angle LOP=180 degree(being co interior angles)
angle JPO + 85 =180
angle JPO =180-85
angle JPO =95
since angle JPO is equal to KPN ,angle KPN is 95 degree
From a stick 2y metres long, I cut a piece of length 4y centimetres. What fraction of the original stick remains?
Answer: [tex]\dfrac{49}{50}[/tex]
Step-by-step explanation:
Given
Length of the stick is [tex]2y\ m[/tex]
A piece of [tex]4y\ cm[/tex] is cut
We know, 1 m=100 cm
So, [tex]2y\ m[/tex] in cm is [tex]200y\ cm[/tex]
Remaining length after cut is
[tex]\Rightarrow 200y-4y=196y[/tex]
Fraction of length that is left after the cut is
[tex]\Rightarrow \dfrac{196y}{200y}\\\\\Rightarrow \dfrac{49}{50}[/tex]
Thus, [tex]\frac{49}{50}[/tex] fraction of original stick remains after cut
The reflector of a satellite dish is in the shape of a parabola with a diameter of 4 feet and a depth of 2 feet. To get the maximum reception we need to place the antenna at the focus. a. Write the equation of the parabola of the cross section of the dish, placing the vertex of the parabola at the origin. Convert the equation into standard form, if necessary. What is the defining feature of the equation that tells us it is a parabola
Answer:
[tex]x^2 = 2y[/tex] --- equation
[tex](x,y) = (0,\frac{1}{2})[/tex] --- focus
[tex]y = -\frac{1}{2}[/tex] --- directrix
[tex]Width = 2[/tex] ---- focal width
Step-by-step explanation:
Given
[tex]depth = 2[/tex]
[tex]diameter = 4[/tex]
Required
The equation of parabola
The depth represents the y-axis. So:
[tex]y = 2[/tex]
The diameter represents how the parabola is evenly distributed across the x-axis.
We have:
[tex]diameter = 4[/tex]
-2 to 2 is 4 units.
So:
[tex]x = [-2,2][/tex]
So, the coordinates of the parabola is:
[tex](-2,2)\ and\ (2,2)[/tex]
The equation of the parabola is calculated using:
[tex]x^2 = 4py[/tex]
Substitute (-2,2) for (x,y)
[tex](-2)^2 = 4p*2[/tex]
[tex]4 = 8p[/tex]
Divide by 8
[tex]p = \frac{4}{8}[/tex]
[tex]p = \frac{1}{2}[/tex]
So, the equation is:
[tex]x^2 = 4py[/tex]
[tex]x^2 = 4 * \frac{1}{2} * y[/tex]
[tex]x^2 = 2y[/tex]
The defining features
(a) Focus
The focus is located at:
[tex](x,y) = (0,p)[/tex]
[tex](x,y) = (0,\frac{1}{2})[/tex]
(b) Directrix (y)
[tex]y = -p[/tex]
[tex]y = -\frac{1}{2}[/tex]
(c) Focal width
[tex]Width = 4p[/tex]
[tex]Width = 4*\frac{1}{2}[/tex]
[tex]Width = 2[/tex]

(x+5)²=32
find the solution
justify answer
Answer:
x = -5 ±4sqrt(2)
Step-by-step explanation:
(x+5)²=32
Take the square root of each side
Sqrt((x+5)²)=±sqrt(32)
x+5 = ±sqrt(16*2)
x+5 = ±4sqrt(2)
Subtract 5 from each side
x+5-5 = -5 ±4sqrt(2)
x = -5 ±4sqrt(2)

Gillian swears her computations for the
following equations prove they do not
intersect. Her brother who just finished
learning about intersecting lines told her they
definitely intersect because the slopes are
different. Gillian remembered that logic from
class and then decided she needed to be able
to prove intersection by using algebra.
Although there are multiple strategies, how
might she prove intersection without graphing
of the following equations?
4x +3y = 6 and 6x + 2y = 10
Step-by-step explanation:
Given
Two lines are [tex]4x+3y=6[/tex] and [tex]6x+2y=10[/tex]
Two lines [tex]a_1x+b_1y=c_1[/tex] and [tex]a_2x+b_2y=c_2[/tex] will intersect when
[tex]\dfrac{a_1}{a_2}\neq \dfrac{b_1}{b_2}[/tex]
for the given lines
[tex]a_1=4,a_2=6,b_1=3,b_2=2[/tex]
[tex]\therefore \dfrac{4}{6}\neq \dfrac{3}{2}\\\\\dfrac{2}{3}\neq\dfrac{3}{2}[/tex]
Hence, lines are intersecting

The total surface area of a cube is 433.5 cm2.
Find its volume.
Answer:
Step-by-step explanation:
The area of 1 face is s^2
The area of 6 faces is 6s^2
6s^2 = 433.5 Divide by 6
s^2 = 433.5 / 6
s^2 = 72.25 Take the square root of both sides
sqrt(s^2) = sqrt(72.25)
s = 8.5
Normally you would find the volume of parallelepiped by using L * W * H
Since L W and H are all equal in a cube, the volume = s^3
S^3 = 8.5^3 = 614.125
Given csc(A) = 65/16 and that angle A is in Quadrant I, find the exact value of sec A in simplest radical form using a rational denominator . Someone please help me!
Answer:
[tex]secA = \frac{65}{63}[/tex]
Step-by-step explanation:
[tex]cosec A = \frac{65}{16}\\\\sin A = \frac{1}{cosecA} = \frac{16}{65}\\\\cos^2 A = 1 - sin^2 A[/tex]
[tex]= 1 - (\frac{16}{65})^2\\\\=\frac{4225-256}{4225}\\\\=\frac{3969}{4225}\\[/tex]
[tex]cos A = \sqrt{\frac{3696}{4225}} = \frac{63}{65}[/tex]
[tex]secA = \frac{1}{cosA} = \frac{65}{63}[/tex]
Find the equation of a line that passes through the point (3,5) and has a gradient of 2.
Leave your answer in the form
y=mx+c
Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (3, 5) into the partial equation
5 = 6 + c ⇒ c = 5 - 6 = - 1
y = 2x - 1 ← equation of line
what is the probability of rolling a number that is greater than 4 on a number cube?
a.) 1/6
b.) 1/3
c.) 1/2
d.) 2/3
=========================================================
Explanation:
E = event space = {5,6}
The event space represents the set of all things we want to happen: namely rolling a 5 or a 6, since they are larger than 4.
S = sample space = {1,2,3,4,5,6}
The sample space is the set of all possible outcomes, whether we want them to happen or not. We have 6 possible outcomes.
Divide the number of items in each set
n(E) = 2
n(S) = 6
probability = n(E)/n(S) = 2/6 = 1/3
There's a 1 in 3 chance of rolling a number greater than 4.

Answer:
Base = 7
Height = 10
Area = 35
Step-by-step explanation:
Area is 35.
7 * 10 = 70
70/2 = 35
Base = 7 (Given)
Height = 10 (Given)
Answer:
base: 7 (yd)
height: 10 (yd)
area: 35 (yd²)
Step-by-step explanation:
To find the area of a triangle, multiply the base and height, then, divide the product by 2. The quotient is the area of the triangle.
[tex]7*10=70.[/tex]
[tex]70/2=35.[/tex]
I, therefore, believe the area of this triangle is 35 yd.
