Answer: Choice A) If Amber and Jorge each sell 5 trees in one week, they will earn the same amount
The amount they earn is $200 each.
========================================================
Explanation:
Let's form the equation for the amount Amber earns.
She starts off at $150, and then we add on 10x dollars. The 10x is because she earns 10 dollars per tree, and we have x be the number of trees sold.
Overall we can say her equation is y = 150+10x
This is the same as y = 10x+150
----------
Since Jorge's equation is y = 25x + 75, we can apply substitution to solve for x
y = 10x+150
25x+75 = 10x+150 .... replace y with 25x+75
25x+75-10x = 150 ... subtract 10x from both sides
15x+75 = 150
15x = 150-75 ... subtract 75 from both sides
15x = 75
x = 75/15 .... divide both sides by 15
x = 5
If they sell 5 trees per week, then Amber and Jorge earns the same amount of money.
That amount earned is
Amber: y = 10x+150 = 10*5+150 = 50+150 = 200 dollars
Jorge: y = 25x+75 = 25*5+75 = 125+75 = 200 dollars
Both earn $200 per week from selling 5 trees for that week. This helps confirm we have the right answer.

1.8 divide by 0.72 explain
Answer:
0.40
Step-by-step explanation:
Change the divisor 1.8 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
7.2 ÷ 18 = 0.40
and therefore:
0.72 ÷ 1.8 = 0.40
Both calculated to 2 decimal places.
Solve for k, please!
2(k − 5) = 12
Answer:
k = 11
Step-by-step explanation:
Expand brackets
2k - 10 = 12
add 10 on both sides
2k = 22
divide both sides by 2
k = 11
The time a student sleeps per night has a distribution with mean 6.06 hours and a standard deviation of 0.55 hours. Find the probability that average sleeping time for a randomly selected sample of 35 students is more than 6.15 hours per night.
Answer:
The probability is 0.16602
Step-by-step explanation:
We start by calculating the z-score
We have this mathematically as;
z-score = (x-mean)/SD/√n
From the question,
we have x = 6.15
mean = 6.06 hours
standard deviation = 0.55 hours
n = 35
Substituting these values, we have
z-score = (6.15-6.06)/0.55/√35
z-score = 0.09/0.55/5.92
z-score = 0.97
So the probability we want to calculate is:
P ( z > 0.97)
we make use of the standard normal distribution table here
The value is; 0.16602
Usually Holly leaves home to school at 9:00, however today she left home 20 minutes later. In order to be at school on time she increased her usual speed by 20% and still was at school 15 minutes later than usual. What is her usual time from home to school
Answer:
Her usual time from home to school is 30 minutes
Step-by-step explanation:
At any point in time;
distance = speed * time
Here, we want to calculate the normal time she spent going from home to school
Let the normal time be x minutes
And the normal speed be t m/min
Today, she increased her speed by 20%
Her speed today will be t + 20/100 * t =
1.2t m/min
Her distance from how to school normally is
xt meters
Now what this means is that, at the increased speed, she was able to get to school 5 minutes earlier
What we are saying is although, she lost 20 minutes initially, she was able to beat down the lateness by 5 minutes
So, the time spent on her increased speed journey is;
(x-5) minutes
At any point in time, the distance will be equal;
Thus, mathematically;
xt = 1.2t(x-5)
xt = 1.2xt - 6t
6t = 1.2xt-xt
6t = 0.2xt
t cancels out
0.2x = 6
x = 6/0.2
x = 30 minutes

The areas of two similar triangles are 18cm^2 and 8cm^2. One of the sides of the first triangle is 4.5cm. What is the length of the corresponding side of the other triangle? Please answer ASAP!!! Thank you!!!
Answer:
3 cmStep-by-step explanation:
The area is the product of two dimensions, therefore the scale factor is:
A/A' = (b*r*h*r)/(b*h) = r²r² = 18/8r = √9/4 = 3/2 = 1.5The length of the corresponding side will be:
a/a' = ra' = a/ra' = 4.5 / 1.5 a' = 3 cmDescribe the motion of a particle with position (x, y) as t varies in the given interval. x = 6 sin(t), y = 4 cos(t), − ≤ t ≤ 3

If you take out a loan for $4,000 and you will owe $4,920 after 2 years, what is the rate of simple interest? Express your answer as a percentage rounded to the nearest tenth of a percent if necessary, but do not include the percent sign.
Answer:
11.5
Step-by-step explanation:
Answer:
11.5
Step-by-step explanation:
you have to use this equation to solve it [r = (1/t)(A/P - 1)] and basically just plug the numbers in to get 11.5. (you could also use one of those online calculators)
r = (1/2)((4920/4000) - 1) = 0.115
r = 0.115

XLiV represents 64 true ya false
Answer:
False
Step-by-step explanation:
Given
[tex]XLIV = 64[/tex]
Required
True or False
The above numeral can be split as follows:
[tex]XLIV = XL + IV[/tex]
X means 10 and L means 50.
But because X (10) which is smaller comes before L (50), XL is executed as:
[tex]XL = -10 + 50[/tex]
[tex]XL = 40[/tex]
In Roman numerals;
[tex]IV = 4[/tex]
Substitute 40 for XL and 4 for IV.
[tex]XLIV = 40 + 4[/tex]
[tex]XLIV = 44[/tex]
Hence;
[tex]XLIV = 64[/tex] is false

Grapes cost $2.70 per pound. You buy 2.5 pounds of grapes and give the cashier $10. How much change do you receive
Answer:
$3.25
Step-by-step explanation:
The grapes costs $2.70 per pound but you're buying 2.5 pounds so take $2.70 x 2.5 = $6.75. Now u just take $10 - $6.75 which equals $3.25 and thats ur answer.
Answer:
You receive 3.25 cash back.
Step-by-step explanation:
2.70 x 2.5 = 6.75
6.75 + ? = 10
A = 3.25

Find the specified value.
(2x +5)
a. Using the figure to the right, find the value of x.
b. Using the figure to the right find the value of y.
Answer:
a. The value of x is [tex]38^{o}[/tex].
b. The value of y is [tex]25^{o}[/tex].
Step-by-step explanation:
a. Applying the vertically opposite principle,
(2x + 5) = (3x - 33)
2x + 5 = 3x - 33
33 + 5 = 3x - 2x
38 = x
⇒ x = [tex]38^{o}[/tex]
b. Sum of angles on a straight line = [tex]180^{o}[/tex]
So that,
(4y - 1) + (3x - 33) = [tex]180^{o}[/tex]
But,
( 3x - 33) = (3x38 - 33)
= 114 - 33
= [tex]81^{o}[/tex]
(4y - 1) + [tex]81^{o}[/tex] = [tex]180^{o}[/tex]
4y - 1 = [tex]180^{o}[/tex] - [tex]81^{o}[/tex]
= [tex]99^{o}[/tex]
4y = [tex]99^{o}[/tex] + 1
= [tex]100^{o}[/tex]
y = [tex]\frac{100}{4}[/tex]
= [tex]25^{o}[/tex]
y = [tex]25^{o}[/tex]
The value of x is [tex]38^{o}[/tex], and y is [tex]25^{o}[/tex].

Your answer Shadae has 2/4 of a pizza. Robin has 3/8 of a pizza. How much pizza do the girls have altogether? Your answer Samantha drank 1/5 of a gallon of water for breakfast. She drank 3/10 vater after her afternoon workout. How much water did she drink in a
Answer:
Part A. The girls have 7/8 pizza all together.
Part B. Samantha drank 5/10 or 1/2 water that day.
Step-by-step explanation:
Part A. The answer is 7/8 because 2/4 is the same thing as 4/8.
2/4 = 4/8
4/8 + 3/8 = 7/8.
So, for the first question the answer is 7/8.
Part B. The answer is 5/10 because 1/5 = 2/10
1/5 = 2/10
2/10 + 3/10 = 5/10
Hope this helps! :)
