Anthony Tedesco sold his used mountain bike and accessories for $276. If he received five times as much money for the bike as he did for the accessories, find how much money he received for the bike.
Answer:
$230
Step-by-step explanation:
To find out how much he received for the bike ONLY, you have to multiply a number by 5 because it is 5 TIMES the accessories.
45x5=230<-- How much he got from the bike.
45<--How much he got from the accessories.
230+45=276<--How much he got from the bike AND accessories.

Savannah is going to invest $220 and leave it in an account for 12 years. Assuming
the interest is compounded continuously, what interest rate, to the nearest tenth of a
percent, would be required in order for Savannah to end up
with $430
Answer:
5.7%
Step-by-step explanation:
The formla for calculating compound interest is expressed as;
A = P(1+r)^t
A is the amount = $430
P is the principal = $220
r is the rate
t is the time = 12 years
Substitute and get r;
430 = 220(1+r)^12
430/220 = (1+r)^12
1.955 = (1+r)^12
1.057 = 1+r
r = 1-1.057
r = 0.057
r = 5.7%
The interest rate is 5.7%

Answer:
y = (x -1)² -16
Step-by-step explanation:
Note the location of the vertex (point A) on the graph. Its x-coordinate is readily identifiable as 1. Its y-coordinate is some value between -15 and -20, closer to -15. (If you go to the trouble of finding the vertex coordinates, you discover they are (1, -16).)
Once you have determined what the vertex is, you can compare the offered answer choices to the vertex form ...
y = (x -h)² +k
where (h, k) are the vertex coordinates. That is, you are looking for an answer choice that is something like ...
y = (x -1)² -16

Answer:
p = - 2x + 54
Step-by-step explanation:
The price-demand linear equation is
p = mx + b
which is the equation of a straight line in slope-intercept form
The parameters here are m = slope and b = y-intercept in line equation terms
x is the number of shirts sold and p is the price
Using values given, we can generate two equations which can solve for the parameters of the linear equation
To sell 10 shirts, the price has to be $34
==> 34 = m x 10 + b = 10m + b
Switch sides to get 10m + b = 34 (1)
To sell 20 shirts, the price has to be $14
==> 14 = 20m + b
Switch sides to get 20m + b = 14 (2)
Subtract (2) from (1) to eliminate the term b
(1) - (2)
==> 10m+b - (20m+b) = 34 - 14
==> 10m + b - 20m - b = 20
==> 10m - 20m = 20
==> - 10m = 20
==> m = 20/(- 10) = - 2.4
==> m = - 2.0
This term is also referred to as the elasticity of demand ie how much demand changes with respect to price change. It is negative here because as you increase the price, the demand decreases
Now that we have value for m all we have to do is plug it into one of the equations (1) or (2) and solve for b
Using equation (2),
20(- 2) + b = 14
==> - 40 + b = 14
==> 0 + b = 14 + 54(Add 48 on both sides)
==> b = 54
So the price-demand equation is

Using proportions, it is found that:
a. The equations are:
1. 24x+28(5-x)=132.4. 24(5-x)+28x=132.b. You would have saved $8 by switching the colors of the dining room and living room.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For item a, considering that 5 cans were bought, there are two options:
x cans of white paint and 5 - x cans of blue paint.5 - x cans of white paint and x cans of blue paint.Hence the equations are given by:
1. 24x+28(5-x)=132.4. 24(5-x)+28x=132.The solution for x is given by:
120 - 24x + 28x = 132
3x = 12
x = 4.
Considering the possible solution, of 4 cans of blue paint and 1 can of white paint.
Exchanging the colors, the price would be of:
4 x 24 + 1 x 28 = 124.
132 - 124 = $8.
You would have saved $8 by switching the colors of the dining room and living room.

Valerie gives her dog 12 ounces of food in the morning and 12 ounces of food at night there are 75 ounces of dog food in a bag after how many feedings will she need to buy a new bag of dog food explain how you know Valerie will need to buy a new bag of dog food after blank feedings
Answer:
Valerie will need to buy a new bag of dog food after 6 feedings because she would have 0.25 of feedings left.
Step-by-step explanation:
Total number of ounces of dog food = 75 ounces
Ounces that is fed to the dog is = 12 Ounces in the morning and 12 ounces at night.
Hence:
12 ounces = 1 feeding
75 ounces = x
Cross Multiply
12x = 75
x = 75/12
x = 6.25 feedings
Valerie will need to buy a new bag of dog food after 6 feedings because she would have 0.25 of feedings left.
consider triangle xyz. what is the approximate length of side yz? a. 13.3 units b. 38.2 units c. 15.7 units d. 47.1 units
The length of side yz is 15.7 units.
The link between the angles and sides of all kinds of triangles, including acute, obtuse, and right-angle triangles, is known as the law of sines. It asserts that for all sides and angles in a certain triangle, the ratio of a triangle's side length to the sine of an angle opposite that side is the same.
You must know two sides of an angle in a triangle or two sides and an angle across from one of them in order to employ the law of sines. You will discover the law of sines in this article, along with its definition, formula, applications, difficulties, and proof. You will also learn when to employ the rule of sines.
Law of sines is expressed as follows: x/sin X = y/sin Y = c/sin Z.
We have the following:
X = 32°
z = 24
Z = 180 - 32 - 94 = 54°
Substituting the value in x / sin X = y / sin Y = z / sin Z
We get,
x/sin (32) = 24 / sin (54)
x = sin ( 32) × (24) / sin (54)
x ≈ 15.7 units
The length of the side yz is equal to x = 15.7 units.

Stefanie bought a package of pencils for $1.75 and some erasers that cost $0.25 each. She paid a total of $4.25 for these items, before tax.
Exactly how ,any erasers did stefanie buy?
Answer:
(4.25-1.75)/0.25=10
she bought 10 erasers
Answer:
10 Erasers
Step-by-step explanation:
We can establish the following equation:
TP = NP*PP + NE*EP
Where:
TP = Total price; (4.25)
NP = Number of pencil packages; (1)
PP = Pencil Package's Price; (1.75)
NE = Number of erasers; (What we are looking for)
EP = Erasers Price; (0.25);
Then:
4.25 = 1*1.75 + NE*0.25;
4.25 - 1.75 = NE*0.25;
2.5/0.25 = NE;
10 = NE.
