A remote control airplane with an original price of $85 is on sale for $76.50. What is the percent of the discount?
Answer:
10% dicount
Step-by-step explanation:
76.50 / 85.00 = .9
The airplane cost 90% of its original value, meaning you have a 10% discount
10% of 85 = .1 x 85 = 8.50
85.00 - 8.50 = 76.50

Given: t is tangent at B
is diameter
If m = 110°, then m =
70
80
110
Answer:
70
Step-by-step explanation:
Given
∠PDB = 110°
PDis the tangent to the circle whose centre is E
Construction
Join points D and E.
∠DPE= 90° [Since angle in a semi circle is 90°]
Also ∠PDE = 90° [Since radius ⊥ tangent]
From the figure we have,
∠PDB=∠PDE + ∠DBE
i.e. 110° = 90° + ∠DBE
Therefore, ∠DBE =20°
Now in ΔBED, BE = ED [Radii]
So, ∠EDB = ∠EBD =20°
In ΔBPD, we have
∠DPE = 90° & ∠DBE = 20°
Therefore, ∠DPB = 70°
Answer:
70 is the correct answer

Five friends want to travel on a trip. The bus ticket price is $50 for each friend, and the rooms and meals for everyone will cost $850.
To pay for the trip, friends work in the local shop. Each of them is paid $5 per hour. If each friend works the same number of hours, how many hours must each friend work so that there will be enough money to pay for the entire cost of the trip?
Answer this pls I'm this accounts cousin help me
Answer:
Step-by-step explanation:
Okay so first you need to find out how much money it will cost in total.
$50*5
=$250
$250+$850=
$1,100
Now, $1,100 divided by 5
1,100/5
=220 hours
And there are 5 friends so divide the total amount hours by 5.
220/5
=44 hours
So you see, each friend will need to work 44 hours.
I hope this helped :)

log2 (X^2+3x+2)=1 state the universe and solve each of the following for x.
By "state the universe" I suppose you mean "domain". log₂(x ² + 3x + 2) is defined for
x ² + 3x + 2 = (x + 1) (x + 2) > 0 → x < -2 or x > -1
(To solve the inequality, consider values of x between the ones that make the expression exactly equal to 0, in this case x = -2 and x = -1. We have, for instance, for x = -3, that (-3)² + 3(-3) + 2 = 2 > 0, so x ² + 3x + 2 > 0 for all x < -2.)
Now solve the equation: Write both sides as powers of 2 to eliminate the logarithm on the left:
[tex]\log_2(x^2+3x+2)=1\implies 2^{\log_2(x^2+3x+2)}=2^1\implies x^2+3x+2=2[/tex]
Solve the remaining quadratic:
x ² + 3x + 2 = 2
x ² + 3x = 0
x (x + 3) = 0
x = 0 or x = -3
Both of these solutions are within the presribed domain (-3 < -2 and 0 > -1), so we're done.
A glassblower can produce several sets of simple glasses in about 3 hours. When the glassblower works with
an apprentice, the job takes about 2 hours. Write an equation that can be used to find the amount of time t, in
hours, it would take for the apprentice to make the same number of sets of glasses when working alone.
Using the together rate, it is found that it would take the apprentice 6 hours to make the same number of sets of glasses when working alone.
What is the together rate?The together rate is the sum of each separate rate.
In this problem, the rates are:
Glassblower: 1/3.Apprentice: 1/x.Together: 1/2.Hence, applying the equation for the together rate:
[tex]\frac{1}{2} = \frac{1}{x} + \frac{1}{3}[/tex]
[tex]\frac{x + 3}{3x} = \frac{1}{2}[/tex]
[tex]2x + 6 = 3x[/tex]
[tex]x = 6[/tex]
It would take the apprentice 6 hours to make the same number of sets of glasses when working alone.

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 5(m∠Y) −240°. Find m∠Y.
The value of m∠Y is
9514 1404 393
Answer:
∠Y = 55°
Step-by-step explanation:
Complementary angles have a sum of 90°.
∠S + ∠Y = 90°
(5∠Y -240°) +∠Y = 90°
6∠Y = 330° . . . . . . . . . . . . add 240°, collect terms

the correct values are ( 3, -2)

(3,-2)
Step-by-step explanation:
x=13/3+2/3y

line a passes through the points (3,4) and (-1,2). line b passes through the points (-12,0) and (-6,-4). at what point do the lines intersect
Answer:
The point of intersection of the two lines is;
(-9,-2)
Step-by-step explanation:
What we have to here is to get the equation of both lines, solve simultaneously and get the intersection points
For the first line;
The general form is
y = mx + b
formula for the slope is;
m = (y2-y1)/(x2-x1)
The points (3,4) and (-1,2)
m = (2-4)/(-1-3) = -2/-4 = 1/2
So the equation is;
y = 1/2x + b
To get b, let us substitute coordinates of the first point;
4 = 1/2 * 3 + b
4 = 3/2 + b
b = 4 - 3/2
b = (8-3)/2 = 5/2
So the equation is;
y = 1/2x + 5/2
For the second line;
Slope;
m = (-4-0)/(-6+12) = -4/6 = -2/3
The equation is;
y = -2x/3 + b
Let us substitute the first
0 = -2/3(-12) + b
0 = 8 + b
b = -8
The equation is;
y = -2x/3 - 8
Now , we want to get the intersection point
To do this, we have to solve both equations simultaneously;
Since we have an expression for y in both cases, let us equate both y
-2x/3-8 = 1/2x + 5/2
Multiply through by 6
-4x - 48 = 3x + 15
-4x-3x = 15 + 48
-7x = 63
x = 63/-7
x = -9
To get x;
Recall;
y = -2x/3 - 8
y = -2/3(-9) - 8
y = 6 - 8
y = -2
