Answer:
$333.5
Step-by-step explanation:
First we have to find 45% of 230 and then add that value to 230
(we can also find 145% of 230, which is essentially the same thing)
so 45% of 230 is:
230*(45/100)= $103.5
230+103.5= $333.5

cross-multiply:
2x/5 = 4/1
2x = 20
x = 10
Derek bought his truck for $30,000. The value has dropped by $900 each year. He determined that the value of his truck (V) can be modeled by: V = 30,000 - 900x where x is the number of years since he bought his truck.
In how many years will his truck be worth $4,800?
Answer:
28 years
Step-by-step explanation:
The difference between 30,000 and 4,800 is 25200. So we divide this number by 900 to find out how many years it will take for the truck to depreciate to this value
for a function,x cannot what
a) repeat
b) multiply
Answer:
A ::repeat
Step-by-step explanation:
A function is a relation in which the members of the domain (x-values) DO NOT repeat. So, for every x-value there is only one y-value that corresponds to it. y-values can be repeated.

Answer:
The figure should be 56 units squared.
Step-by-step explanation:
The long side is 14 units long (6+6+2) and the short side is 4 units long, so 14 multiplied by 4 is 56.

Solve triangles using the law of sines
Answer:
BC = 18.7
Step-by-step explanation:
Here, we want to solve the triangle using the law of sines
According to the law, the ratio of the measure of the side of a triangle and the sine of the angle that faces the side is a constant for all sides of the triangle
Mathematically;
a/sin A = b/sin B = c/sin C
with reference to this particular triangle, we have it that;
20/sin 80 = BC/ sin 67
BC = 20 * sin 67/sin 80
BC = 18.7

Answer:
x = 4
Step-by-step explanation:
Given
[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{x^2+7x+12}[/tex] ← factor the quadratic
[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{(x+3)(x+4)}[/tex]
Multiply through by (x + 3)(x + 4) to clear the fractions
3(x+3) - (x + 4) = x + 9 ← distribute and simplify left side
3x + 9 - x - 4 = x + 9
2x + 5 = x + 9 ( subtract x from both sides )
x + 5 = 9 ( subtract 5 from both sides )
x = 4
Ann buys a dress in a sale. The normal price of the dress is £36 and it is reduced by 20%. Work out the sale price of the dress.
Reduced by 20% means it is on sale for 80% of the original price ( 100% - 20% = 80%)
Multiply the original price by 80%
36 x 0.8 = 28.80
The sale price is £28.80

Sea 2x + 5,088 números de casos Infectados en Sto. Dgo.
Entonces x + 2x + 5,088 = 43,956
x + 2x = 43,956 - 5,088

The equation g(t)=2+23.7t−4.9t2 models the height, in meters, of a pumpkin t seconds after it has been launched from a catapult. Is the pumpkin still in the air 8 seconds later? Explain or show how you know.
Answer:
The pumpkin is not in the air
Step-by-step explanation:
The equation is
[tex]g(t)=2+23.7t-4.9t^2[/tex]
Let us find when the pumpkin will reach the ground
[tex]0=2+23.7t-4.9t^2\\\Rightarrow -49t^2+237t+20=0\\\Rightarrow t=\frac{-237\pm \sqrt{237^2-4\left(-49\right)\times 20}}{2\left(-49\right)}\\\Rightarrow t=-0.08,4.91[/tex]
So, the pumpkin will reach the ground at 4.91 seconds. Hence, at 8 seconds the pumpkin will reach the ground.
ORAt [tex]t=8\ \text{s}[/tex]
[tex]g(8)=2+23.7\times 8-4.9\times 8^2\\\Rightarrow g(8)=-122\ \text{m}[/tex]
The height of the pumpkin is negative 122 m. This means it is lower than the ground. So, the pumpkin is not in the air 8 seconds later.

Suppose on April 1, a gag store sold a total of 27 widgets and wombats combined. If widgets cost
$0.75, wombats cost $1.25, and the store received a total of $27.75 for these two items, how
many of each item did the store sell?
Answer:
Widgets: 12
Wombats: 15
Step-by-step explanation:
Let x represent widgets
y represent wombats
Set up the equations
(1) x + y = 27
(2) 0.75x + 1.25y = 27.75
Solve equation (1), x + y = 27 for x
x = 27 - y
Substitute 27- y for x into equation (2)
0.75(27 - y) + 1.25y = 27.75
0.5y + 20.25 = 27.75
0.5y = 7.5
y = 15
Substitute 15 for y into equation (2)
x = 27 - 15
= 12
Ashlee was born on 12/24/2002. How many eight-digit codes could she make using the digits in her birthday?
Answer:
840
Step-by-step explanation:
Given the date:
Birth date = 12/24/2002
Number of digits = 8 = 8! = (8*7*6*5*4*3*2*1) = 40320
Repeated digits :
digit 2 = 4 times = 4! = (4 * 3 *2 * 1) = 24
digit 0 = 2 times = 2! = 2*1 = 2
Therefore the number of 8 digit codes that can be formed is :
8! / (4! * 2!)
40320 / (24 * 2)
40320 / 48
= 840
Hence, 840 8 digit codes can be formed
David had $60 to spend at the store. He bought two games that cost $7.45 each a baseball cap that cost $12.95, and two books that cost $9 each. How much money did David have left over when he finished shopping?
Answer:
Step-by-step explanation:
Total amount = 60$
Cost of two games = 7.45 x 2 = 14.9
Cost of baseball cap = 12.95
Cost of two books = 9 x 2 = 18
Total amount he spent = 14.9+12.95+18 = 45.85
Amount remaining = 60 - 45.85 = 14.15

You gotta use PEMDAS:
ParenthesisExponentMultiplicationDivisionAdditionSubtractionStep 1
x^2+50x-600=x^2 You gotta Remove parenthesis
Step 2
x^2+50x−600=x^2 subtract x^2 from sides
50x-600=0
Step 3
50x-600=0 add 600 to the sides
50x=600
Step 4
50x=600 Divide the sides by 50
So therefore, your answer is x=12

find the side length of a cube with a volume of 69 to the 3 power yds . If necessary, round your answer to the nearest tenth.
Answer:
the side length of the cube is 4.10
Step-by-step explanation:
The computation of the side length of the cube is shown below:
As we know that
The volume of the cube is side^3
So,
69^3 = s^3
Now the side length of the cube is
= ∛69
= 4.10
Hence, the side length of the cube is 4.10
