Hector's family traveled 7 10 of the distance to his grandmother's house on Saturday. They traveled 2 3 of the remaining distance on Sunday. What fraction of the total distance to his grandmother's house was traveled on Sunday?
Answer: 1 / 5 of the total distance.
Step-by-step explanation:
They traveled 7/10 of the distance on Saturday. This means that on Saturday, the fraction left was:
= 1 - 7/10
= 3/10 of the distance
On Sunday, they traveled 2/3 of this remaining distance. The fraction of the distance traveled is therefore:
= 2/3 * 3/10
= 6 / 30
= 1 / 5 of the total distance.
A farmer is creating a budget for planting soybeans and wheat. Planting soybeans costs $200 per acre and planting wheat costs $500 per acre. He wants to spend no more than $100,000 planting soybeans and wheat. What is the "multiplier" for soybeans?
Answer:
5 acres < soybeans < 495
2 acres < wheat < 198 acres
Step-by-step explanation:
If farmer plans to plant minimum of soybeans, it should be 5 acres of soybeans costing $1000. The remaining cost of $98,000 will be available for maximum of wheat, i.e., 198 acres of wheat.
Similarly, if we go for minimum possible planting for wheat, it should be 2 acres, and then resulting in 495 acres for soybeans
5 acres < soyabeans < 495
2 acres < wheat < 198 acres
Answer:
The multiplier for soybeans is 200, which is dollars per acre.
Step-by-step explanation:
5 acres ≤ soybeans ≤ 495 acres (constraint)
2 acres ≤ wheat ≤ 198 acres (constraint)
150w + 125s = 100,000
This would represent 150 acres of wheat and 125 acres of soybeans. The acres of wheat would add up to $75,000 because 150 x 500 = 75,000 and the acres of soybeans would add up to $25,000 because 125 x 200 = 25,000. (example of a solution, there are more possible)
show that the equation x^3 + x - 3 has a solution between 1 and 2
Answer:
see explanation
Step-by-step explanation:
Evaluate the polynomial at x = 1 and x = 2
x = 1 : 1³ + 1 - 3 = 1 + 1 - 3 = - 1
x = 2 : 2³ + 2 - 3 = 8 + 2 - 3 = 7
Then ( 1, - 1 ) → (2, 7 )
Shows the polynomial goes from y = - 1 to y = + 7
The change in sign indicates the graph crosses the x- axis between 1 and 2
Thus indicating a solution between x = 1 and x = 2

Step-by-step explanation:
Ethan invested $9,500 in an account paying an interest rate of 2 3/4% compounded monthly. Henry invested $9,500 in an account paying an interest rate of 3 3/8% compounded quarterly. After 9 years, how much more money would Henry have in his account than Ethan, to the nearest dollar?
Answer:
691
Step-by-step explanation:
Henry would have $1,005.94 more than Ethan in his account after 9 years.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
To solve this problem, we can use the formula for compound interest:
[tex]A = P(1 + r/n)^(^n^t^)[/tex]
where A is the amount after t years,
P is the principal
r is the annual interest rate,
n is the number of times the interest is compounded per year, and
t is the time in years.
For Ethan:
P = $9,500, r = 2.75% = 0.0275 (since it is compounded monthly, n = 12), and t = 9
[tex]A = 9,500(1 + 0.0275/12)^(^1^2^\times^9^)[/tex]
= $12,817.84
For Henry:
P = $9,500,
r = 3.375% = 0.03375 (since it is compounded quarterly, n = 4), and
t = 9
[tex]A = 9,500(1 + 0.03375/4)^(^4^\times^9^)[/tex]
= $13,823.78
The difference in the amounts is:
$13,823.78 - $12,817.84 = $1,005.94
Therefore, Henry would have $1,005.94 more than Ethan in his account after 9 years.

A company was able to incite staff from 100 employees to 214 employees. What was the percentage increase in staff
Answer:
114%
Step-by-step explanation:
A company was able to incite staff from 100 employees to 214 employees. What was the percentage increase in staff?
Percentage Formula is given as:
New value - Old value/Old value × 100%
New value = 214
Old value = 100
Hence:
Percentage increase = 214 - 100/100 × 100
= 114/100 × 100
= 114 %
Therefore, the percentage increase = 114%

Answer:
1. x + 5 = 12
2. 2x = 54
Step-by-step explanation:
Let
The unknown number = x
1. The sum of a number and 5 is 12.
x + 5 = 12
x = 12 - 5
x = 7
2. Twice a number is 54
2x = 54
x = 54/2
x = 27
3. Thrice a number increase by 2 is less than 50.
3x + 2 < 50
3x < 50 - 2
3x < 48
x < 48/3
x < 16
4. One half the sum of a number and 4 is less than 28.
1/2(x + 4) < 28

Mark spends $36 at a basketball game. He buys a T-shirt for $22. He then buys a bottle of water for $4 and 2 tacos. How much is each taco?
Answer:
each taco is $7.
Step-by-step explanation:
In total he spent $36. He bought a shirt for $22 and a bottle of water for $4.
22+4= 26
36-22= 14
14 divided by 2= 7
Answer:
each taco is $5.
Step-by-step explanation:
Let's think about like Mark starts off with $36. Take away $22 for that t-shirt he bought. Now he has $14. He uses $4 for water, now he has $10. The rest of his money is spent on tacos. $10/2 tacos is $5 for each taco. :)
