Answer: 160°C
Step-by-step explanation:
From the question, we are informed that a particular substance was heated by 4°C every hour for 40 hours.
The total change in temperature will be gotten by multiplying the change in temperature every hour by the total number of hours used. This will be:
= 4°C × 40
= 160°C

find the angles of a cyclic quadrilateral ABCD in Angle A = (4x+20 )^0 , Angle B = (3x+5 )^0 , Angle C =(4y)^0 , Angle D = (7y-5)^0
Answer:
<A = 120degrees
<B = 80degrees
<C = 60degrees
<D = 100degrees
Step-by-step explanation:
For a cyclic quadrilateral, the sum of the adjacent angle of the quadrilateral are equal, hence;
<A + <C = 180
<B + <D = 180
Substitute the given values
4x+20+4y = 180
4x+4y =1 60
x + y = 40 ...1
Similarly;
3x+5+7y - 5 = 180
3x+7y = 180 ....2
Solving simultaneously
x + y = 40 ...1 .....* 3
3x+7y = 180 ....2 ...... *1
__________
3x + 3y = 120 ...1 .
3x+7y = 180 ....2
Subtract
3y - 7y = 120 - 180
-4y = -60
y = 15
Since x+y = 40
x + 15 = 40
x = 40 - 15
x = 25
<A = 4x+20
<A = 4(25)+20
<A = 120degrees
<C = 180 - <A
<C = 180 - 120
<C = 60degrees
<B = 3x+5
<B = 3(25)+5
<B = 80degrees
<D = 180 - <B
<D = 180 - 80
<D = 100degrees

I’m trying to bring my grade up by doing some makeup work so can someone please answer this for me please
Answer:
A and B (answer #2)
Step-by-step explanation:
right triangles: c^2 = a^2 + b^2
c is the largest side
for A: c = 5, a = 3, b = 4
5^2 = 3^2 + 4^2
25 = 25, so A is a right triangle
for B, c = 13, a = 5, b = 12
13^2 = 5^2 + 12^2
169 = 169, so B is a right triangle
for C, c = 4, a = 2, b = 3
4^2 = 2^2 + 3^2
16 ≠ 13, so C is not a right triangle
So, A and B are right triangles.

Do yall like chicken :3 also what is 2+2?
Answer:
Yes and no solution :)
Step-by-step explanation:
No explanation needed for the first part.
2 as a fraction is 2/1
So rewrite as 2/1 + 2/1
We can multiply the whole equation by lets say.... 428
Now we have 856/428 + 856/428
Now we can put 0 at the other side of the equation... because... yes
856/428+856/428 = 0
Now lets just move one of these to the other side of the equation :)
856/428 = -856/428
Now I dont know, how about we cancel out the denominators.
856=-856
now if we move the right side back to the left... we get
1712=0
This equation is not true therefor 2+2 has no solution
Riley took 5 tests in science. Each test had a different score. The mean score of the tests was 90%. The median score of the tests was 85%. Based on this information, select the two statements that must be true.
A: More than half of the scores were 85% or greater.
B: More than half of the scores were 90% or greater.
C: There were no scores less than 85%
D: There were no scores less than 90%
E: At least one score was exactly 85%
F: At least one score was exactly 90%
Answer:
A: More than half of the scores were 85% or greater.
E: At least one score was exactly 85%
Step-by-step explanation:
Here the 5 test would be taken in science so 85% would be the result of one of the test
Also 85% represent the median so it means there are 2 values more and 2 values less
So there are 3 results with 85% or greater
Hence, the option A and Option E is correc
And, the rest of the options are wrong
Answer:
A and E

A triangular prism has a height of 5m, a length of 204cm, and a height of 1293 mm. Find its volume.
The answer is 1 x 10^something i can't really see what it is. Please explain how to do this.
Answer:
In the triangular prism calculator you can easily find out the volume of that solid. A general formula is volume = length * base_area; the one parameter you always need to have given is the prism length, and there are four ways to calculate the base - triangle area. Our triangular prism calculator has all of them implemented, isn't it awesome?
The specific formulas look as follows:
Length * Triangular base area given triangle base and height
It's this well-known formula mentioned before:
volume = length * 0.5 * b * h
Length * Triangular base area given three sides (SSS)
If you know the lengths of all sides, use the Heron's formula to find the area of triangular base:
volume = length * 0.25 * √( (a + b + c) * (-a + b + c) * (a - b + c) * (a + b - c) )
Length * Triangular base area given two sides and the angle between them (SAS)
You can calculate area of a triangle easily from trigonometry:
volume = length * 0.5 * a * b * sin(γ)
Length * Triangular base area given two angles and a side between them (ASA)
You can calculate that using trigonometry:
volume = = length * a² * sin(β) * sin(γ) / (2 * sin(β + γ))

Samuel wants to attend a four-year university with an annual tuition of $16,700.He has $21,000 in savings and earned a grant for $6,00 for each year of college.how much more does samuel need to pay for the tuition for all four years?
Answer:
21,800
Step-by-step explanation:
Total costs is $16,700 x 4 years = 66,800
He saved 21,000 + receives 24,000 (6,000x4) grants for a total of 45,000 saved.
costs of 66,800 - receipts of 45,000 = 21,800 needed.

Answer:
The area of the composite figure is 189 square meters.
Step-by-step explanation:
First, partition the composite figure into 2 distinct shapes: a rectangle and a square on the top.
The formula for finding the area is: A = lw, or Area = length * width.
Area for figure number 1 (the square): 7 * 7 = 49
Area for figure number 2 (the rectangle): 20 * 7 = 140
Now, just add up both figures' areas, and find the answer:
140 + 49 = 189
I hope this somewhat helped. Have a great day!
