Complete question is;
Ilona is at a friends home that is several miles from her home. She starts walking at a constant rate in a straight line toward her home.
The expression -2t + 10 gives the distance, in miles, that Ilona is from her home after t hours. Select True or False for each of the following.
1. The friends home is 10 miles from Ilonas home
2. The distance Ilona has walked away from her friends home after t hours is given by the absolute value of -2t
3.The negative sign in the term indicates that Ilona is walking toward her home
4. Ilona is walking at a rate of 10 miles per hour
Answer:
Statements 1 & 2 are correct.
Step-by-step explanation:
We are told that the expression -2t + 10 gives the distance, in miles, that Ilona is from her home after t hours.
Now, we know that distance = speed x time
Now, from the expression -2t + 10
It's clear that 2t is a distance value.
This means that the speed used in going home is 2 miles/hr
This means that at t hours, she has walked 2t miles from her friends home.
Thus, statement 2 is true because an absolute value of -2t will be 2t.
Since 2t is subtracted from 10 in the expression and 2t is the distance she has walked from her friends house at Time, t. It means that 10 miles is the distance from her friends house to her house.
Thus, statement 1 is also true

Answer: m∠2 =60
60=4x+12
subtract 12 from both sides
60-12=4x+12-12
60-12=4x
48=4x
divide both sides by 4
48÷4=4x÷4
48÷4=x
x=12
Plug it into the equation
4(12)+12=
48+12=
m∠2 =60
another proof is that they are congruent

Mrs. Wally cut a 21 foot long ribbon into four equal lengths. How many feet long was each length of ribbon
the answer is:
Each equal length of ribbon is 5.25 ft
Step-by-step explanation:
21 divided by 4 is 5.25
To find the number of distributed quantities division operator is used. Each length of ribbon was 5.25 foot long.
What is division ?Division is a mathematical operation used to divide a number into equal parts. When a number is divided by another number, a quotient and remainder is obtained.
Given length of ribbon = 21 foot
Number of parts it has to be divided = 4.
So, to get the length of each part divide the total length by 4.
Thus, the length of each part is 21/4 = 5.25 foot.
Hence, the length Mrs. Wally' s each ribbon is 5.25 foot.

Find two numbers with a sum of 14 and a difference of 4:
Answer:
First number --> x
Second number --> y
x + y = 14 --> x = 14 - y
x - y = 4
so
14 - y - y = 4
14 - 2y = 4
2y = 10
y = 5
so
x = 14 -5
x = 9

Hence, the area of the trapezium is A=40cm²
Darrell is interested in getting a puppy and goes to the local animal shelter. He finds a puppy that he likes and begins the process of making the purchase. Because they want to neuter the puppy, Darrell has to sign a contract and pay for the puppy and then leave the puppy there until Monday while the puppy is in surgery. When Darrell returns on Monday, he finds out that the puppy did not survive the surgery and died over the weekend. Darrell's heart is broken, but he wants to enforce the contract. Will he win?

In this question, the given statement is true because, for the dogs, its standard neutering age is six to nine months, so long as they would be safe puppies as young as eight weeks can be neutered.
The Male dog neutralization avoids disease of the testicles or reduces the risk of other conditions like a prostatic disease. Its tangled male dog may also have less motivation to go about, which may assist with certain behavioral problems. It can decrease aggressive behavior in many dogs.Suppose that 2000 is placed in an account that pays 13% interest compounded each year. Assume that no withdrawals are made from the account. Do not do any rounding.
A:Find the amount in the account at the end of 1 year.
B: Find the amount in the account at the end of 2 years.
The amount will be $2260 in the account at the end of 1 year. The amount will be $2553.8 in the account at the end of 2 years.
What is Compound interest?Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.
A = P(1+r/100)ⁿ
Where:
A = the future value of the investment or loan
P = the principal investment or loan amount
r = the interest rate (decimal)
n = the number of compound periods
As per the question, the given data will be:
p = $2000
r = 13%
t = 1 year
To calculate the amount in the account at the end of 1 year.
A = P(1+r/100)ⁿ
Substitute the values of p,r, and t in the formula,
A = 2000(1 + 13/100)¹
A = 2000(1 + 0.13)¹
A = 2000(1.13)
A = $2260
To calculate the amount in the account at the end of 2 years.
A = 2000(1 + 13/100)²
A = 2000(1 + 0.13)²
A = 2000(1.13)²
A = $2553.8
Thus, the amount will be $2260 in the account at the end of 1 year. The amount will be $2553.8 in the account at the end of 2 years.

Based on the graph, which inequality is correct for a number that is to the left of -4?
a
−7 > −4
b
−6 −4
d
−4 < −9
Answer:
From the graph, it is clear that the left of -4 will always be lesser than the -4.
and -6 is the left of -4. so -6 will be lesser than -4.
so, [tex]-6 < -4[/tex] is the correct option.
Therefore, the option 'd' is the correct answer.
Step-by-step explanation:
Let us analyze all the given inequalities
Given the inequality
[tex]-7\:>-4[/tex]
As -7 can not be greater than -4, so [tex]-7\:>-4[/tex] is false.
Given the inequality
[tex]-8>-4[/tex]
As -8 can not be greater than -4, so [tex]-8>-4[/tex] is false.
Given the inequality
[tex]-4 < -9[/tex]
As -4 can not be lesser than -9, so [tex]-4 < -9[/tex] is false.
Given the inequality
[tex]-6 < -4[/tex]
As -4 is always greater than -6, so [tex]-6 < -4[/tex] will be true.
From the graph, it is clear that the left of -4 will always be lesser than the -4.
and -6 is the left of -4. so -6 will be lesser than -4.
so, [tex]-6 < -4[/tex] is the correct option.
Therefore, the option 'd' is the correct answer.

For the school's sports day, a group of students prepared 12 1/2 litres of lemonade. At the end of the day they had 2 5/8 litres left over. How many litres of lemonade were sold?
Given :
For the school's sports day, a group of students prepared 12 1/2 litres of lemonade. At the end of the day they had 2 5/8 litres left over.
To Find :
How many litres of lemonade were sold.
Solution :
Initial amount of lemonade, I = 12 1/2 = 25/2 litres.
Final amount of lemonade, F = 2 5/8 = 21/8 litres.
Amount of lemonade sold, A = I - F
A = 25/2 - 21/8 litres
A = 9.875 litres
Therefore, 9.875 litres of lemonade were sold.
Hence, this is the required solution.
Pedro makes a base monthly salary of $1500. As a vendor, he must sell $20000 worth of items per month. He also makes a 4% commission on all sales beyond the monthly quota. If Pedro sold $26000 worth of items this month, what is his total salary for the month including base salary and commission to the nearest dollar?
Answer:
$2540
Step-by-step explanation:
Given parameters:
Base salary of Pedro = $1500
Amount of commission on sales = 4%
Sales = $26000
Unknown:
His total salary including base salary and commission = ?
Solution:
His total salary;
Total salary = Base Salary + (percent on commission x sales)
Total salary = $1500 + ([tex]\frac{4}{100}[/tex] x $26000)
Total salary = $1500 + $1040
Total salary = $2540
