I think its -18
Step-by-step explanation:
-2/9 = 4 /m
-2 ×-2 = 4
so you would do the same to the bottom
9 ×-2 = -18

Triangle DEF is dilated to create triangle DAB. What scale factor was used?
please hurry in less than 10 min
Answer:
Not sure how you would word it but the bigger triangle is 2 times larger than DEF.
Step-by-step explanation:
DE=4
AE=4
4+4=8
AD=8
Hope this helps!!
The scale factor used to create DAB from triangle DEF is 2.
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
The length of the base of the triangle DEF is 4 units and of DAB is 8 units.
The length of the height of DEF is 3 units and that of DAB is 6 units.
From this, we conclude that the scale factor is 2 as 8 is a multiple of 2×4 and 6 is a multiple of 2×3.

The seventh grade class is raising money to have a class trip at the end of the year. They began the year with $1500. They now have $1650 in the account. What is the percent of increase for the money the class has raised ?
Answer:
The percent of the increase for the money the class raised is 10 %
Step-by-step explanation:
Because if you divide 1500 by 10 you get 150 that means 150 is 10 % of 1500 and if you add 150 to 1500 you get 1650 so the increase of money the class raised is 10 %

In a survey of 3,500 people who owned a certain type of car,1,925 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer: percent of the people surveyed that were satisfied with the car= 55%
Step-by-step explanation:
Step 1
Total Number of people in the survey who owned certain type of car = 3,500
Number of people that would buy that type of car again = people surveyed that were satisfied with the car= 1,925
Step 2
Percentage of people satisfied with the car= people surveyed that were satisfied with the car/Total Number of people in the survey who owned certain type of car x 100
=1925 / 3500 x 100
=0.55 x 100
=55%

An account with an initial deposit of 3,500 earns 7.25% annual interest, compounded continuously. How much will the account be worth after 30 years? Round to the nearest cent.
Answer: $28,575.05
Step-by-step explanation:
Formula: FV = (1+r/n)^nt
FV = future value of the deposit
P = principal or amount of money deposited
r = annual interest rate (in decimal form)
n = number of times compounded per year
t = time in years.
3,500(1+7.25%)^30=28,575.05468
i need to identify the slope and the y-intercept of the line with a given equation, the given equation is y = 1/2x +5 . i need to graph it aswell.
Answer:
y-intercept: 5
slope: 1/2
Step-by-step explanation:
The equation y=1/2x+5 is an example of y-intercept form(y=mx+b). This is where b represents the y-intercept and m represents the slope. I will not graph this for you but can explain it.
First plot the y-intercept on the graph. (0.5). Then use the slope to find the next point off of the y-intercept. So for example, the next point would be (2,6).
A TV programme begins at 7:45 p.m. and ends 50 minutes later

What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
It is given that a TV programme begins at 7:45 p.m. and ends 50 minutes later.
Addition is one of the fundamental mathematical operations we utilize on a daily basis. We employ addition of numbers in a variety of contexts. Working with time or money, such as adding up bills and receipts, is one of the most frequent daily uses for adding numbers.
We have to apply the addition operation by splittiong the time as,
=7:45 p.m + 50 minute
=7:45 p.m + 15 minute + 35 minute
=8:00 pm + 35 minute
=8:35 pm
Thus, a TV programme begins at 7:45 p.m. and ends 50 minutes later.At 8:35 pm time it will finish.

[tex]\frac{a+b+c}{3}[/tex][tex]=42[/tex]
and
[tex]\frac{a+b+c+d}{4}[/tex][tex]=40[/tex]

[tex]a + b + c = 126[/tex]
[tex]\frac{126+4}{4} = 40[/tex]

Annie spent 2.5 hours doing homework. She spent 1/3 of the time on her history project. She spent 3/5 of the remaining time solving math problems. After that, Annie spent all remaining time writing an essay. How much time did Annie spend writing the essay?
Step-by-step explanation:
2.5 hours = 150 min
1/3 of 150 is 50 min, which means she spent 50 min on her history project = 100 min leftover

Answer:
19/15
Step-by-step explanation:
To solve this, we need to add 2/3 and 3/5, to do this, we need to find the LCM of 3 and 5, that is 15. We multiply 2/3 by 5/5 and 3/5 by 3/3. This gets us 10/15 + 9/15. When we add those together, we get 19/15.

yes
no
Answer:
yes
Step-by-step explanation:
y = -1/2x + 7
6 = -1/2(2) + 7
6 = -1 + 7
6 = 6
y = 8x - 10
6 = 8(2) -10
6 = 16 - 10
6 = 6
