Tomas is a commercial real estate agent who earns a yearly salary of $82,500 and a 2.5% commission on his total sales. If Tomas sold properties that totaled $3.75 million in sales during one year, what are Tomas’s earnings for that year?
Answers
Answer:
$176,250
Step-by-step explanation:
Multiply $3.75 million by Tomas commission on his total sales.
Since you can't multiply a percentage you have to turn the commission into a decimal by moving it two spaces to the left. (Note: if it doesn't have a decimal add one add the end of the number then move it two spaces to the left)
$3,750,000 x .025 or 0.025 = $93,750
Add $93,750 to Tomas yearly salary
$93,750 + $82,500 = $176,250
So
If Tomas sold properties that totaled $3.75 million in sales during one year, his earnings for that year would be $176,250

the formula for slope is rise over run, or y1-y2 divided by x1-x2. we can choose either number as y1 or y2 but it needs to stay consistent with x

He drew a best-fit line and determined its equation.
Evaluate how many texts a 15 year old would send each day according to Keiko's trend line equation.
Answers
Answer:
67.69
Step-by-step explanation:
You have your equation, t = -1.63 a + 92.14
a = age
a = 15
if you update your equation to fill in for a you get:
= -1.63 (15) + 92.14
-1.63 x 15 = -24.45
-24.45 + 92.14 = 67.69
67.69
Answer:
67.69
Step-by-step explanation:
You have your equation, t = -1.63 a + 92.14
a = age
a = 15
if you update your equation to fill in for a you get:
= -1.63 (15) + 92.14
-1.63 x 15 = -24.45
-24.45 + 92.14 = 67.69

Step-by-step explanation:
Given equation,
→ (2/3)x + 19 = 35
Now the value of x will be,
→ (2/3)x + 19 = 35
→ (2/3)x = 35 - 19
→ (2/3)x = 16
→ x = 16 ÷ (2/3)
→ x = 16 × (3/2)
→ x = (16 × 3)/2
→ x = 48/2
→ [ x = 24 ]
Hence, the value of x is 24.

you are running a ten mile race. The function d(t) = 1-8 |t-40| represents the distance in miles you are from the water stop after t minutes. interpret the intercepts. Explain what each represents in this context
Answers
The y-intercept of the graph represents the distance in miles that you are from the water stop at time t = 0. In this case, the y-intercept is d(0) = 1 - 8|0 - 40| = 1 - 8|-40| = 1 - 8(-40) = 1 + 320 = 321. This means that at time t = 0, you are 321 miles from the water stop.
In summary, the x-intercepts represent the times at which you are exactly one mile from the water stop, and the y-intercept represents the distance in miles that you are from the water stop at time t = 0.

A community has an empty field ready for development and plans to place a playground in the center. A model of the plan for the project is shown. A large rectangle with dimensions of 21 feet by 36 feet. Inside it is a smaller rectangle with dimensions of 15 feet by 12 feet. How much area is left for development in the field outside the playground? 756 ft2 576 ft2 288 ft2 180 ft2
Answers
Answer:
576 ft²
Step-by-step explanation:
Large rectangle:
21·36=756
Smaller rectangle:
15·12=180
Find leftover area:
756-180
=576 ft²
Hope this helps! :)
Answer:
The area that is left for development in the field outside the playground is 576 ft².
Step-by-step explanation:
To calculate the area left for development in the field outside the playground, we need to subtract the area of the smaller rectangle from the area of the larger rectangle.
The area of a rectangle is the product of its width and length:
\(\boxed{\sf Area\;of\;a\;rectangle=width \times length}\)
The dimensions of the larger rectangle are:
width = 21 ftlength = 36 ftThe dimensions of the smaller rectangle are:
width = 15 ftlength = 12 ftTherefore, the development area can be calculated as follows:
\(\begin{aligned}\sf Development \;area&=\sf Area_{large\;rectangle}-Area_{small\;rectangle}\\\\&=(21 \times 36)-(15 \times 12)\\\\&=756-180\\\\&=576\; \sf ft^2\end{aligned}\)
Therefore, the area that is left for development in the field outside the playground is 576 ft².

Hey guys...I really need help on this... Compare the original figure to the enlarged figure. Which ratios can be used to find the scale factor? Check all that apply.
Please don't copy google or others websites...
I'm giving out more points again...
Answers
Answer:
A and C.
Step-by-step explanation:
Remember that to find the scale factor, we can write a ratio between each of the corresponding sides.
In other words, the scale factor k will be:
\(k=\frac{\text{Enlarged Side}}{\text{Corresponding Original Side}}\)
Most importantly, their sides must be corresponding.
So, let's go through each of the answer choices.
A)
We have:
\(k=\frac{\text{Enlarged}}{\text{Original}}=\frac{6.5}{3.25}\)
In our figures, we can see that 6.5 from our scaled figure indeed corresponds to 3.25 from our original figure. So, A is correct.
B)
We have:
\(k=\frac{\text{Enlarged}}{\text{Original}}=\frac{3.25}{6.5}\)
This is not correct because 3.25 is our original, not our enlarged. It should be flipped, like choice A. So, B is not correct.
C)
We have:
\(k=\frac{\text{Enlarged}}{\text{Original}}=\frac{3}{1.5}\)
We can see that 3 from our enlarged figure indeed corresponds with 1.5 from our original figure. So, choice C is also correct.
D)
We have:
\(k=\frac{\text{Enlarged}}{\text{Original}}=\frac{1.5}{3}\)
Similarly to B, this is not correct because our enlarged number should be in the numerator while our original number should be in the denominator. So, D is not correct.
E)
We have:
\(k=\frac{\text{Enlarged}}{\text{Original}}=\frac{1.5}{3.25}\)
This is not correct because the sides do not represent the scaled figure. Both of the given side lengths are from the original figure, and so we cannot determine the scale factor from this.
So, our final answers are A and C.
And we're done!

Answers
Answer:
3/4
Step-by-step explanation:
Since (p, r) lies on the line y = x + b,
we have,
r = p + b -----eq(1)
Since (2p, 5r) lies on the line y = 2x + b,
we have,
5r = 2(2p) + b -----eq(2)
Sub the value of r from eq(1) in eq(2),
5(p + b) = 4p + b
⇒ 5p + 5b = 4p + b
⇒ 5b - b = 4p - 5p
⇒ 4b = -p
⇒ b = -p/4
sub in eq(1)
r = p + (-p/4)
= p - p/4
= 3p/4
⇒ r = 3p/4
⇒ r/p = 3/4
Answer:
3/4
Step-by-step explanation:
We have two lines:
r = p + b eq(1)
5r = 4p + b eq(2)
eq(2) - eq(1)
4r = 3p
dividing by 4p
r/p = 3/4

The unit price of the 13 oz bottle is $0.18 per oz
The unit price of the 30 oz bottle is $0.53 per oz
The 13 oz bottle for $2.34 is a better deal.
Step-by-step explanation:
Unitary method: diving the number that you want to find out over the already known number. (just try to understand this lol) :)
13 oz = $2.34
13 oz bottle is $? per oz
\(\frac{2.34}{13}\) = 0.18
1 oz = $0.18
(double check: 0.18×13=2.34)
30 oz = $15.90
30 oz bottle is $? per oz
\(\frac{15.9}{30}\) = 0.53
1 oz = $0.53
(double check: 0.53×30=15.9)
The 13 oz bottle for $2.34 is a better deal.

Leon is scuba diving at an elevation of −72
feet when his friend signals to come higher to see a sea turtle. Leon makes 3 ascents, each an equal distance, to reach an elevation of −18
feet, where the sea turtle is located.
What was Leon's elevation after his second ascent?
Answers
Answer: -36 feet
Step-by-step explanation:
72-18 = 54 feet ascended
54 feet / 3 ascents = 18 feet per ascent
18 feet * 2 ascents = 36 feet
-72+ 36 = -36 feet
54/3= 18, 18*2=36
72-36= 36
