Answer:
Infinitely many solutions
Step-by-step explanation:
2(4 + x) = 8 + 2x 8 + 2x = 8 + 2xBoth sides are same, it means regardless the value of x the equation is correct. The equation has infinitely many solutions

Number line graph with open circles on 0 and 15 and shading in between.
Number line graph with closed circles on 0 and 15 and shading in between.
Number line graph with closed circle on 15 and shading to the right.
Number line graph with open circle on 15 and shading to the right.
Number line with closed circle on 15 and shading to the right. That's because 32 - 17 = 15 and since you need at least 15 more dollars the circle would be closed and shading to the right since it's at least meaning 15 or more.

Answer:
area = 73.37 cm²
Step-by-step explanation:
area of circle:
A = π5² = 78.5 cm²
area of 80° segment:
(80/360)(78.5) = 17.44 cm²
area of isosceles triangle w/ 5 cm legs and 80° angle:
sin 40° = b/5
0.6428 = b/5
b = 3.214
base = 2(3.21) = 6.43 (we only figured for one-half of the base)
cos 40° = h/5
0.7660 = h/5
height = 3.83
A = 1/2(6.43)(3.83) = 12.31 cm²
area of unshaded part:
17.44 - 12.31 = 5.13 cm²
area of total shaded part:
78.5 - 5.13 = 73.37 cm²

Compare investing $1500 at 9% compounded monthly for 11 years with investing $1500 at 14% compounded monthly for 11 years.
Answer:
Final amount after 11 years = $4021.97
Step-by-step explanation:
We will use the formula to get the final amount after t years,
Final amount = [tex]a(1+\frac{r}{n})^{nt}[/tex]
here a = Initial amount
r = Rate of interest
n = Number of compounding in a year
For Initial amount 'a' = $1500
r = 9%
t = 11 years
n = 12 [Compounded monthly]
F = [tex]1500(1+\frac{9}{12})^{12\times 11}[/tex]
= $4021.97

Leah is mixing peanut butter candy (p) that sells for $3.60 per pound with chocolate candy (c) that sells for $2.00 per pound. She needs 50 pounds of the mixture to sell in her store for $2.16 per pound. Which system of linear equations can Leah use to determine the number of pounds of each candy to use?
Answer:
45 pounds of the chocolate candy and 5 pounds of the peanut butter candy.
Step-by-step explanation:
let's define the variables:
p = pounds of peanut butter candy she uses
c = pounds of chocolate candy she uses.
We know that she wants to have a total of 50 pounds of the mixture, then we will have that:
p + c = 50
We also want that these 50 pounds sell for $2.16 per pound.
Then we must have that the price for the candies in the mixture must be equal to the desired price, we can write this as:
p*$3.60 + c*$2.00 = (50 )*($2.16 )
Then we have the system of equations:
p + c = 50
p*$3.60 + c*$2.00 = (50)*($2.16) = $108
To solve this, we first need to isolate one of the variables in one of the equations. I will isolate p in the first equation to get:
p = 50 - c
Now we can replace this in the other equation to get:
(50 - c)*$3.60 + c*$2.00 = $108
Now we can solve this for c.
$180 - c*$3.60 + c*$2.00 = $108
$180 - c*$1.60 = $108
$180 - $108 = c*$1.60
$72 = c*$1.60
$72/$1.60 = c = 45
This means that she should use 45 lb of the chocolate candy, and using the equation:
p + c = 50
p + 45 = 50
p = 50 - 45 = 5
p = 5
She should use 5 lb of the peanut butter candy.
Point B is a point of tangency. Find the radius r of OC.
Answer:
r = 16 units
Step-by-step explanation:
From the figure attached,
AB is the tangent drawn from a point A to the circle C.
BC = r [Radius of the circle]
Length of AC = (18 + r)
AB = 30
By the property of a tangent drawn to a circle,
"Radius of a circle and tangent are perpendicular to each other"
AB ⊥ BC
By applying Pythagoras theorem in ΔABC,
AB² + BC² = AC²
(30)² + r² = (r + 18)²
900 + r² = r² + 36r + 324
36r = 900 - 324
r = [tex]\frac{576}{36}[/tex]
r = 16 units
Malia and Omar want to find the shortest route from their school to a local burger
hangout. The length of Route A is 1.5 times the length of Route B and ¾ the
length of Route C. If Route C is 3 kilometers long, then Route A is how many
kilometers longer than Route B?
Answer:
Route A is 0.75 km longer than route B.
Step-by-step explanation:
Length of route A is 1.5 times the length of route B.
a = 1.5b
[tex]\frac{a}{b}=\frac{15}{10}[/tex]
[tex]\frac{a}{b}=\frac{3}{2}[/tex] --------(1)
Here, a = Length of route A
b = Length of route B
Length of route A is [tex]\frac{3}{4}[/tex] of route C.
a = [tex]\frac{3}{4}c[/tex]
[tex]\frac{a}{c}=\frac{3}{4}[/tex] ------(2)
Here, c = Length of route C
Length of route C = 3 km
Length of route A = [tex]\frac{3}{4}\times 3[/tex] [From equation (2)]
= 2.25 km
Length of route B = [tex]\frac{2}{3}\times 2.25[/tex] [From equation (1)]
= 1.5 km
Difference in route A and route B = 2.25 - 1.5
= 0.75 km
Therefore, route A is 0.75 km longer than route B.

If ∠5 = 137° and ∠7 = 100°, find the measure of ∠1. *
Answer:
m∠1 = 37°
Step-by-step explanation:
if m∠5 = 137 then m∠2 = 43 (supplementary angles)
if m∠7 = 100 then m∠3 = 100 (vertical angles)
m∠1 + m∠2 + m∠3 = 180°
m∠1 + 43 + 100 = 180°

Q : 4(5j + 8 +6j) = ???
Answer:
= 44j+32
j = -8/11
geometric figure it is called a line.
Step-by-step explanation:
Expand the following:
4 (6 j + 5 j + 8)
Grouping like terms, 5 j + 8 + 6 j = (5 j + 6 j) + 8:
4 (5 j + 6 j) + 8
5 j + 6 j = 11 j:
4 (11 j + 8)
4 (11 j + 8) = 4×8 + 4×11 j:
4×8 + 4×11 j
4×8 = 32:
32 + 4×11 j
4×11 = 44:
Answer: 32 + 44 j

Find the value of each variable. Assume it is a 45 45 90 triangle. Round to the nearest tenth.
Answer:
x = 6
y = 45 degrees
Step-by-step explanation:
Here, we want to get the measure of x and y
For a 45-45-90 triangle, the measure of each of the internal angle asides the right angle is 45 degrees
This mean y is 45
To get x, we know we have an isosceles triangle
So the length of the third ungiven leg is x too
Mathematically, the square of the hypotenuse (side facing the right angle) is equal the sum of the squares of the two other sides
(6 √2)^2 = x^2 + x^2
72 = 2x^2
x^2 = 72/2
x^2 = 36
x = √36
x = 6
Timia needs so cash in a hurry she owns her car outright and is considering a title loan. The lender told timia she could borrow 1750 for 1 month
The question is incomplete ; the fee which Timia would pay isn't given. And this is needed to compute the APR on the loan.
I would assume that the fee which Timia would pay as interest on the 1 - month loan is x
Answer:
r = x / 145.83333
Step-by-step explanation:
If interest paid, I = x
Principal, P = $1750
And period (time) of loan = 1 month = (1/12) = 0.0833333
Rate = r
Using the simple interest formula :
Interest = Principal * rate * time
x = 1750 * r * 0.833333
Make r the subject :
x = 145.83333r
Divide both sides by 145.83333
Hence, the rate value , r becomes :
r = x / 145.83333
Therefore, the student can just input the appropriate, interest value in place of x and obtain the correct and exact answer (I do not want to use an hypothetical value for x) .

After eight games the team has won two games lost five and tied one if there season is 24 games how many games will they win at this rate
Answer:
Since the games in total add up to 8, we see that 8 is a factor of 24. It goes in 3 times. Therefore, we have to multiply everything by 3 to get the answer out of 24. There will be 6 wins, 15 losses and 3 tie. That adds up to 24.

if you’re standing on the street 1,300 feet from the bottom of the building, you have to look up at a 23 degree angle to see the top. How tall is the building ? explain or show your reasoning.
Answer:
551.82feet tall
Step-by-step explanation:
WE are given the following from the question;
Distance of me from the bottom of the building = 1300feet (adjacent)
Angle of elevation = 23 degrees
Required
Height (opposite)
Using the SOH CAH TOA identity
Tan theta = opp/adj
Tan 23 = H/1300
H = 1300tan23
H = 1300(0.4245)
H = 551.82feet
Hence the building is 551.82feet tall
