Answer:
x= 500 y= 1500
Step-by-step explanation:
Isolate x or y in the first equation
Isolating for x would be x= -y+2000
Substitute X=-y+2000 into equation 10x+20y=35000
10(-y+2000)+20y=35000
Exapnd the equation above and you should get y=1500
Same steps for finding x by isloating for y
Piano lessons with Ms. Cohen cost $30 for 3/4 of an hour. What is Ms. Cohen's hourly rate?
Answer:
$40.
Step-by-step explanation:
To find the hourly rate, we can divide the price and the time.
We know that Ms.Cohen charges $30 for 3/4 of an hour. So, we will perform:
[tex]30\div\frac{3}{4}[/tex]
We dividing fractions, we keep, change, and flip. Hence:
[tex]=30\times\frac{4}{3}[/tex]
Multiply:
[tex]=\frac{120}{3}=\$40[/tex]
Therefore, the hourly rate is $40.
And this is the hourly rate because it is $40/1 hour. We can ignore the 1, so it’s just $40 per hour.
Answer:
$40
Step-by-step explanation:
If is $30 for 3/4 then you add 1 more to get 4/4 you get $10 added to $40
Q16. Find the area of the shaded region (4 corners) with each side = 12 in.
1 3.14
12 in
Use
12 in
Answer:
D. 30.96 in²
Step-by-step explanation:
The area of the shaded region = area of the the square - area of the circle
= (s²) - (πr²)
s = 12 in
r = radius of circle = ½ of 12 in = 6 in
π = 3.14
Plug in the values into the equation
Area of the shaded region = (12²) - (3.14*6²)
= 144 - 113.04
= 30.96 in²

Does △ABC appear to be the same size and shape as △XYZ? Explain.
Right triangles A B C and X Y Z. A B C has shorter leg equal to 5 and hypotenuse equal to 13. Longer leg B C is horizontal. X Y Z has shorter leg equal to 5 and hypotenuse equal to 13. Hypotenuse X Y is horizontal.
A. Yes; △ABC maps onto △XYZ with a translation and a rotation.
B. Yes; △ABC maps onto △XYZ with a translation and a reflection.
C. Yes; △ABC maps onto △XYZ with a rotation and a reflection.
D. No; the triangles are different sizes.
Answer:
yes
Step-by-step explanation:
Yes, △ ABC appears to be the same size and shape as △ XYZ by SAS similarity, and △ ABC can be mapped by translation and rotation, so option A is correct.
What is triangle?Simple polygons with three sides and three internal angles make up triangles. One of the fundamental geometric shapes, it is represented by the symbol and consists of three connected vertices.
Given:
Right triangles ABC and XYZ. ABC has a shorter leg equal to 5 and a hypotenuse equal to 13,
The triangles ABC and XYZ are similar by SAS similarity, as,
AC = XZ = 5,
AB = YZ = 13
∠ ACB = ∠ XZY
When you translate and then rotate triangle ABC, you will get triangle XYZ.

For the past 25 days, jonathon has read for n minutes each day. His total number of minutes read is 875. Write an equation to express the number of minutes jonathon read.
Answer:
Required equation is: 25n = 875
Step-by-step explanation:
Let n be the number of minutes Jonathon read per day
Now
He read for 25 days and total 875 minutes
The equation will be:
[tex]25n = 875[/tex]
We can solve this equation to find the number of minutes each day
Using Division property of Equality
[tex]\frac{25n}{25} = \frac{875}{25}\\n = 35[/tex]
Hence,
Required equation is: 25n = 875

A survey was conducted in a class with 20 students about their favorite sport. Five students chose basketball, 8 students chose football, and 7 chose soccer. Based on this information, predict how many would NOT choose soccer if there were 460 students in the survey. 150 30b 230 • 160
Answer: 299
Step-by-step explanation:
Out of 20 students, 5 students chose basketball, 8 students chose football, and 7 chose soccer.
Students chose basketball and football=5+8=13
Fraction of students not chose soccer = [tex]\dfrac{13}{20}[/tex]
Assume that the fraction remains the same.
If there were 460 students, then the number of students not chose soccer [tex]=460\times\dfrac{13}{20}\\\\=299[/tex]
Hence, the number of students not chose soccer =299

Which value of m makes the statement true?
76 – 2m < 11 + 3m
13
11
O
8
5
Answer:
13
Step-by-step explanation:
We subtract 76 from both sides
76 - 2m - 76 < 11 + 3m - 76
-2m < 3m - 65
Subtract 3m from both sides
-2m - 2m < 3m - 65 - 3m
-5m < -65
Multiply both sides by -1 and flip the signs
(-5m)(-1) > (-65)(-1)
We get
5m > 65
Divide both sides by 5 and we get
m > 13
