Answer:
x=35
Step-by-step explanation:
Alright so an isosceles triangle is a triangles that has 2 angles that have the same value and those lines tell us which angles are the ones that are the same which would be angle Q and angle R. The lines are almost pointing at those angles. All of the angles will equal 180 so we set up an equation
180=2x + 40 because Q and R have the same value we multiply the 2x by 2
now we have 180=4x+40
step 1 subtract each side by 40
140=4x
step 2 divide each side by 4
35=x

Answer:
10.77
Step-by-step explanation:
by using Pythagoras theorem we can find the distance between the points,
so...
distance between the points, which is the hypotenuse will be xy
difference between the y coordinates will be dy
difference between the x coordinates will be dx
according to pythagoras theorem,
[tex]xy^{2} = dx^{2} + dy^{2} \\xy^{2} = (-6-(-2))^{2} + (-5-5)^{2}\\xy^{2} =(-4)^{2} +(-10)^{2} \\xy^{2} =16+100\\xy^{2} =116\\xy =\sqrt{116} \\xy=10.77[/tex]
what is the distance between the points?! round to the nearest tenth i need to show work
Answer:
8.6
Step-by-step explanation:
To find the distance between two points we use the formula posted below
All we need to do is figure out what the points are on the graph and plug them into the formula... we end up with
the square root of (5-(-2)^2+(2-(-3)^2 and get the answer of 8.602325267
then we round to the nearest tenth and get 8.6

x=3y-1
3x+4y=10
Answer:
y=1, x=2
Step-by-step explanation:
so first solve for y. plus x=3y-1 into the other equation.
so 3(3y-1)+4y=10.
Simplify
9y-3+4y=10 Add 3 to both sides
9y+4y=13 Add
13y=13 . Divide 13 from both sides
y=1
Plug 1 into the first equation.
x=3(1)-1
x=3-1
x=2 and y=1

A board is 48 in long. It must be divided into 4 pieces of equal length, and each cut will cause a waste of 3/16 in. How long will each piece be after the cuts are made?
Answer:
12 pieces
Step-by-step explanation:
Total length of the board = 48 in
It must be divided into 4 pieces of equal length
This means, there will be 3 cut to have 4 pieces
Each cut will cause a waste of 3/16 in.
Total waste = 3 cut × 3/16 in
= (3*3)/16
= 9/16 in
Length of board remaining = Total length of the board - Total waste
= 48 - 9/16
= (768-9)/16
= 759/16 in
How long will each piece be after the cuts are made?
Length of each piece after the cut = Length of board remaining / 4
= 759/16 ÷ 4
= 759/16 × 1/4
= 759/64
= 11.859375

Answer:
y = -2x + 12
Step-by-step explanation:
Step 1: find the slope
y = 1/2x + 5
The equation of the line is
y = mx + c
m - slope
m = 1/2
Note : if two lines are perpendicular to the other, both lines are negative reciprocal of each other
m = -2
Step 2 : using a point slope form
y - y1 = m( x - x1)
( 2 , 5)
x1 = 2
y1 = 5
y - 2 = -2( x - 5)
y - 2 = -2x + 10
y = -2x + 10 + 2
y = -2x + 12
The equation of the line is
y = -2x + 12

After examining daily receipts over the past year, it was found that the green parrot italian restaurant has been grossing over $2200 a day for about 85% of it's business days.
Complete question is;
After examining daily receipts over the past year, it was found that the green parrot italian restaurant has been grossing over $2200 a day for about 85% of it's business days. Using this as a reasonably accurate measure, find the probability that the green parrot will gross over $2200:
A. At least 5 of the next 7 business days.
B. at least 5 of the next 10 business days.
C. less than 3 of the next 5 business days.
d. Exactly 7 of the next 10 business days
e. At least 1 of the next 5 business days.
Answer:
A) P(X ≥ 5) = 0.9262
B) P(X ≥ 5) = 0.9986
C) P(X ≤ 2) = 0.0266
D) P(X = 7) = 0.1298
E) P(X ≥ 1) = 0.9999
Step-by-step explanation:
This is a binomial probability distribution problem and as such we will use the formula;
P(X = k) = C(n, k) × p^(k) × (1 - p)^(n - k)
A. At least 5 of the next 7 business days will be;
P (X ≥ 5) = P(X = 5) + P(X = 6) + P(X = 7)
P(X = 5) = C(7, 5) × 0.85^(5) × (1 - 0.85)^(7 - 5)
P(X = 5) = 0.20965
P(X = 6) = C(7, 6) × 0.85^(6) × (1 - 0.85)^(7 - 6)
P(X = 6) = 0.396
P(X = 7) = C(7, 7) × 0.85^(7) × (1 - 0.85)^(7 - 7)
P(X = 7) = 0.320577
Thus;
P(X ≥ 5) = 0.20965 + 0.396 + 0.320577
P(X ≥ 5) = 0.9262
B. Probability of at least 5 of the next 10 business days will be;
P(X ≥ 5) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)
From online binomial calculator attached, we can see that the answer is;
P(X ≥ 5) = 0.9986
C. Probability of less than 3 of the next 5 business days will be;
P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)
From online binomial calculator attached, we can see that the answer is;
P(X ≤ 2) = 0.0266
D. Probability of exactly 7 of the next 10 business days will be;
P(X = 7) = C(10, 7) × 0.85^(7) × (1 - 0.85)^(10 - 7)
P(X = 7) = 0.1298
e. Probability of at least 1 of the next 5 business days will be;
P(X ≥ 1) = P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)
From third image attached using online binomial calculator, we have;
P(X ≥ 1) = 0.9999

a. Is the relationship between number of towers and number of customers proportional? Explain. Choose the correct answer below and, if necessary, fill in the answer box to complete your choice.
A.
Yes. The ratios of towers to customers (thousands) are all equivalent to a unit rate of nothing.
B.
No. The ratios of towers to customers are not all equivalent.
Answer:
A.
Step-by-step explanation:
Divide 169 by 3.25 and you get 52.
Divide 221 by 4.25 and you get 52.
Do this for all of the rest, and they will all be 52.
Hope this helps!
Yes. The ratios of towers to customers (thousands) are all equivalent to a unit rate of nothing. Therefore, option A is the correct answer.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent.
The given table is
Cell Phone Towers Customers (thousands) Towers
3.25 169
4.25 221
5.25 273
7.25 377
Here, the ratio of Cell Phone Towers : Customers (thousands) Towers
3.25 : 169
= 325/16900
= (325÷325)/(16900÷325)
= 1/52
4.25 : 221
= 425/22100
= 1/52
5.25 : 273
= 525/27300
= 1/52
7.25 : 377
= 725/37700
= 1/52
Therefore, the ratio of given cell phone towers to customers (thousands) towers are equivalent.

In other terms, it is a mathematical statement stating that "this is equivalent to that."
Given:
The cost of the banquet hall = $500,
The cost per ticket = $15,
Total money to be raised = $1000
Write the equation of the number of tickets as shown below,
1000 = 15x

Find the area of the
regular figure below:
A) 160.5 km2
B) 166.2 km2
C) 173.8 km2
D) 182.4 km2
E) 189.1 km2
explain pls
Answer:
Option C : 173.8 km² is the correct answer.
Step-by-step explanation:
Given that:
Side length = 6 kilometers
A shape with 8 sides is called an octagon, therefore, the given figure is an octagon.
Area of octagon is given by;
Area = [tex]2(1+\sqrt{2})a^2[/tex]
Putting a=6
Area = [tex]2(1+\sqrt{2})(6)^2[/tex]
Area = [tex](2+2\sqrt{2})(36)[/tex]
Area = 173.82
Rounding off to one decimal place
Area = 173.8 km²
Hence,
Option C : 173.8 km² is the correct answer.

the circle? Use 3.14 for T.
25 in.
A. 78 square inches
B. 157 square inches
C. 491 square inches
D. 1,963 square inches
Answer:
D. 1,963 square inches
Step-by-step explanation:
Using the formula of the area of the circle A= [tex]\pi[/tex][tex]r^{2}[/tex] and assuming that the radius is 25 inches.
Then,
A = [tex]\pi[/tex](25 inches)^2
A = (3.14)(25inches)^2
