Two years ago, Jose bought $750 worth of stock in a cell phone company. Since then the value of his stock has been DECREASING at an average rate of 5 1/4 % per year. How much is the stock worth now?
Answer:
$671.25
Step-by-step explanation:
To get the amount by which the stock have reduced after 2 years, we will use the interest formula;
Interest = Principal * rate * time/100
Interest = 750*5 1/4 * 2/100
Interest = 750*21*2/400
Interest = $78.75
This means that the value of the stock has reduced by $78.75 after 2 years;
Amount that the stock worth now = $750 - $78.75
Amount that the stock worth now = $671.25

In the sixth grade 3/7 of the students are boys and 5/8 of these boys are in Miss Jones class what fraction of the entire six grade class are the boys in Miss Jones class
Answer:
Think of the entire population of 6th graders here. 3/7 are boys and 4/7 are girls. 5/8 of these boys are in Ms. Jones' class; that fraction would be (5/8)(3/7), or 15/56. This 15/56 represents the fraction of the entire sixth grade class who are in Ms. Jones' class.

x-
Solve the equation for x:
-3(x + 4) + 5x = 24
[tex]-3(x + 4) + 5x = 24\\\\-3x - 12 + 5x = 24\\\\2x - 12 = 24\\\\2x = 36\\\\x = 18[/tex]
The solution for x in this equation is 18.
Answer:
x = 18

Step-by-step explanation:
Step 1: Define
-3(x + 4) + 5x = 24
Step 2: Solve for x
Distribute -3: -3x - 12 + 5x = 24Combine like terms: 2x - 12 = 24Isolate x term: 2x = 36Isolate x: x = 18Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -3(18 + 4) + 5(18) = 24Add: -3(22) + 5(18) = 24Multiply: -66 + 90 = 24Add: 24 = 24Here we see that 24 does indeed equal 24.
∴ x = 18 is the solution to the equation.

Answer:
J.)
Step-by-step explanation:
if you make there width to their length a ratio - like for the top you would do 8/2 - then the bottom is different. They all simplify to 4/1 except the bottom.
12/3 = 4/1
2/.5 = 4/1
10/2.5 = 4/1
10/4 = 5/2
Allan can make 8 pizzas in 15 minutes at the pizza restaurant where he works. 28. __________ If the number of pizzas varies directly with minutes, how many pizzas can Allan make in 3 hours?
Answer:
96 pizzas
Step-by-step explanation:
First, we have to determine how many pizza he can make in one minute = 8/15 = 0.533
Convert 3 hours to minutes = 3 x 60 = 180 minutes
The number of pizzas he would make in 3 hours = 180 x 0.533 = 96 pizzas
Carrie usa 6 limones para hacer 24 onzas líquidas de limonada. Carrie está planeando una gran fiesta y necesita hacer 288 onzas líquidas de limonada. ¿Cuántos limones necesitará usar para mantener la receta proporcional?
Answer:
72 lemons
Step-by-step explanation:
Carrie uses 6 lemons to make 24 fluid ounces of lemonade. Carrie is planning a big party and needs to make 288 fluid ounces of lemonade. How many lemons will she need to use to keep the recipe proportional?
Hence:.
24 fluid ounces = 6 lemons
288 fluid ounces = x lemons
24 x = 288 × 6
x = 288 × 6/24
x = 72 lemons

Complete question :
A company rents out 15 food booths and 20 game booth at the country fair. The fr for a food booth is $200 plus $8 per day. The fee for a game booth is $65 plus $7 per day. The fair lasts d days and all the booths are rented for the entire time. Enter a simplified expression for the amount in dollars that the company is paid.
Answer:
4300 + 260d
Step-by-step explanation:
Given that :
Earning from Food booth cost :
Number of booth * cost
15(200 + 8d)
3000 + 120d
Earning from Game booth :
Number of booths * cost
20(65 + 7d)
1300 + 140d
Total sum :
Total earning from game booth and food booth
3000 + 120d + 1300 + 140d
3000 + 1300 + 120d + 140d
4300 + 260d

Answer:
Not Linear.
Step-by-step explanation:
Answer:
5/4 slope
-7 y intercept.
Step-by-step explanation:
The slope is the number in front of the x. The number in front of the x is 5/4. The slope is 5/4
1. The y intercept is whatever is behind the x or 0 if there is no number following the x.
2. The y intercept is also characterized by being on the same side of the equation as the x.
3. Finally it has no x in it.
In this case the y intercept is -7
Examples
y + 2 = x 2 is not the y intercept. subtract 2 from both sides. y = x - 2. Therefore -2 is the y intercept.
2y = 4x + 6 4 is not the slope. You have to divide by y = 2x+3. So 2 is the slope and 0,3 is the y intercept.
What expressions are equivalent to 6.7 - (-2.5)
Answer:
[tex]6.7-\left(-2.5\right)=9.2[/tex]
Step-by-step explanation:

A coin collection consists of dimes and nickels. If there are a total of 500 coins valued
at $39. how many dimes are there?
Answer:
There are 280 dimes
Step-by-step explanation:
A nickel is worth 5 cents while a dime is worth 10 cents
Let n be number of nickel
d the number of dimes
n + d = 39
Secondly
$39 is same as 3900 cents
So we have;
10d + 5n = 3900
From first equation;
n = 500-d
Put this in second equation;
10d + 5(500-d) = 3900
10d + 2500-5d = 3900
5d = 3900-2500
5d = 1400
d = 1400/5
d = 280
